The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

Canaan's New 5-Nanometer Chips to Escalate ASIC Arms Race With Bitmain

Canaan's New 5-Nanometer Chips to Escalate ASIC Arms Race With Bitmain submitted by LindaLarsson to Bitcoin [link] [comments]

08-11 01:54 - 'Canaan's Co-Chairman was 'Out', Chinese BIG3 Bitcoin Miner Makers under Inner Wars' (self.Bitcoin) by /u/CjOnChain removed from /r/Bitcoin within 964-974min

The Bitcoin miner maker Canaan Creative (NASDAQ: CAN) lately announced that five members of their board are leaving. As told, the terms of office of two directors, namely Jianping Kong and Qifeng Sun, expired on July 31, and three of its independent directors, namely Hong Zhang, Xiaohu Yang and Mei Luo, expired on August 1.
It is noteworthy that all the departing directors are not allowed to seek appointments nor participate in the elections of the board of directors after the expiration of their terms of office.
On July 9, Canaan Creative’s Hangzhou headquarter underwent business registration record modification. Former directors Kong, Sun and Li Jiaxuan, as well as supervisor Tu Songhua withdrew from the board, and Meng Lu was added as the new supervisor. "The corporate contact person also changed from Zhang Jing to Zhang Ning.
According to the news, recently, the founder Zhang Nangeng had come with some Canaan Creative executives from Beijing to Hangzhou, dismissed a number of managers of Hangzhou headquarter, took away the official seal and business license of the company, later that day, some employees called the police.

The same as Bitmain, the first NASDAQ listed Bitcoin miner maker Canaan Creative also built the VIE structure, the main body of the company set up in the Cayman Islands. According to some sources, there has been a power struggle in Canaan Creative, between Zhang’s Beijing office and Kong’s Hangzhou office.
In response to what happened in Hangzhou, Canaan Creative said that, "after the registration modification, the company is running normally, and all subsidiaries in China are headed by Zhang as the company's executive director, general manager and legal representative”.
The power struggle in Canaan is not a single case. As the former industry dominant, BitMain technologies, who has released IPO prospectus in 2018 but with no progress, stuck in a Cayman Islands lawsuit between two founders. Its business is also badly affected.
While another rising star MicroBT’s founder suffered from the disaster behind bars. December 12, 2019, Shenzhen Nanshan Court announced that the criminal suspect Yang Zhenxing was arrested by the crime of official encroachment. Outpost OnChain confirmed the news with MicroBT at the first moment.

[link]3
Dr. Yang was graduated from Tsinghua University, had been the former miner chip design supervisor in BitMain and worked for the mysterious miner maker ‘FriedCat’. He had designed so-called BE300 chip using a "full custom methodology", the chip failed to go into mass production with the disappearance of FriedCat.
Yang disclosed the "Full Custom Methodology” to the founder of BitMain, Zhan Ketuan, which can significantly reduce the cost and power consumption of the chip. Yang worked part-time to help design the S7 miner (1385 chip) and the S9 miner (1385 chip) that made BitMain's mining dominance possible.
In 2016, Yang left BitMain and built up Shenzhen MicroBT Electronic Technology Company. Subsequently, MicroBT released a number of high-performance crypto mining products, quickly squeezed into the market, which had shaken the market dominance of BitMain. Later on, BitMain launched a patent ownership and infringement dispute lawsuit against MicroBT.
However, a source said that there are some hidden facts behind Yang's arrest. As the source acknowledged, during the end of 2019, the lawsuit between BitMain and MicroBT made significant progress, law enforcement officers from Beijing has come to Shenzhen to handle the case. Right at this point, as the chairman, general manager and the actual beneficiary of MicroBT, Yang arrested by a 100 thousands RMB worth embezzlement case. The case between BitMain suspended after that. The timeliness of the embezzlement case and the identity of the informer are worthy of considering.
Satoshi Nakamoto may not have imagined the emergence of ASIC chips when he published the Bitcoin white paper. The mining machine, a money-printing artifact, has created wealth for mining giants such as BitMain, MicroBT and Canaan Creative in just a few years. While the rapid accumulation of wealth, pathetic stories have also been staged, from the vanish of the FriedCat to the BitMain’s official seal wresting case. The road less traveled may not be the right path for everyone.

The Economics of "ASICs" for RandomX

Regarding RandomX and ASICs, people seem to mis-understand the interaction between hardware/software, the costs of development/manufacture of world class semiconductors, and the economics of ASIC mining.
These on-chip, bare metal processing units that RandomX requires are highly advanced, and required to make chips "smart." An "ASIC" takes simple dumb functions and iterates them on bare silicon, rather than as a software abstraction (a layer higher) on top of the underlying hardware.
There are a few things that RandomX didn't include, meaning that a fully optimized "ASIC" processor could eliminate some unused logic units to make room for the others particular to RandomX. At most, the designers of RandomX estimate a 2x improvement over current CPUs.
2x. That's almost nothing when you consider the economics of what it takes to make one of these things. As someone who spent 5 years as a process engineer in a world class semicon fab, I can tell you the design, testing, manufacture and turnaround time for advanced CPUs is enormous. Nothing like dumb SHA256 ASICs or simple memory chips. You better be gettting a huge return on investment to go to all that trouble.
2x is nothing. Bitcoin ASICs arose because there was something on the order of 1000x speed advantage over GPUs. That's the kind of economics you need to recoup the costs involved. Not to mention that you are still competing against the ever progressing AMD and Intel advancements (and probably ARM and RISC-V soon enough). Bitmain has very little competition. They have the patents and the process for new ASICs.
So no, it's unlikely, for years, that anyone will develop an economically viable "ASIC" (lol) for RandomX.
What we might see are CPU manufacturers use RandomX as a benchmark for their new units, since you will have the promise of a sort of "rebate" by mining Monero. In fact that could be an awesome marketing opportunity for Monero.

Epic Cash AMA Recap with CryptoDiffer Community

CryptoDiffer team Hello, everyone! We are glad to meet here: Max Freeman (@maxfreeman4), Project Lead at Epic Cash Yoga Dude (@Yogadude), PR&Marketing at Epic Cash Xenolink (@Xenolink), Advisor at Epic Cash
Max Freeman Project Lead at Epic Cash Thanks Max, we are excited to be here!
Yoga Dude PR&Marketing at Epic Cash Hello Everyone! Thank you for having us here!
Xenolink Advisor at Epic Cash Thank you to the CryptoDiffer team and CryptoDiffer community for hosting us!
CryptoDiffer team Let`s start from the first introduction question: Q1: Can you introduce yourself to the community? What is your background and how did you join Epic Cash?
Yoga Dude PR&Marketing at Epic Cash
Hello! My background is Marketing and Business Development, I’ve been in crypto since 2011 started with Bitcoin, then Monero in 2014, Ethereum in 2015 and at some point Doge for fun and profit. I joined Epic Cash team in September 2019 handling PR and Marketing.
I saw in Epic Cash what was missing in my previous cryptos — things that were missing in Bitcoin and Monero especially.
Xenolink Advisor at Epic Cash
Hello Cryptodiffer Community, I am not an original co-founder nor am I a developer for the Epic Cash project. I am however a community member that is involved in helping scale this project to higher levels. One of the many beauties of Epic Cash is that every single member in the community has the opportunity to be part of EPIC’s team, it can be from development all the way to content producing. Epic Cash is a community driven project. The true Core Team of Epic Cash is our community. I believe a community that is the Core Team is truly powerful. EPIC Cash has one of the freshest and strongest communities I have seen in quite a while. Which is one of the reasons why I became involved in this project. Epic displayed some of the most self community produced content I have seen in a project. I’m actually a doctor of medicine but in terms of my experience in crypto, I have been involved in the industry since 2012 beginning with mining Litecoin. Since then I have been doing deep dive analysis on different projects, investing, and building a network in crypto that I will utilize to help connect and scale Epic in every way I can. To give some credit to those people in my network that have been a part of helping give Epic exposure, I would like to give a special thanks to u/Tetsugan and u/Saurabhblr. Tetsugan has been doing a lot of work for the Japanese community to penetrate the Japanese market, and Japan has already developed a growing interest in Epic. Daku Sarabh the owner and creator of Crypto Daku Robinhooders, I would like to thank him and his community for giving us one of our first large AMA’s, which he has supported our project early and given us a free AMA. Many more to thank but can’t be disclosed. Also thank you to all the Epic Community leaders, developers, and Content producers!
Max Freeman Project Lead at Epic Cash
I’m Max Freeman, which stands for “Maximum Freedom for Mankind”. I started working on the ideas that would become Epic in 2018. I fell in love with Bitcoin in 2017 but realized that it needs privacy at the base layer, fungibility, better scalability in order to go to the next level.
CryptoDiffer team
Really interesting backgrounds I must admit, pleasure to see the team that clearly has one vision of the project by being completely decentralized:)
Q2: Can you briefly describe what is Epic Cash in 3–5 sentences? What technology stands behind Epic Cash and why it’s better than the existing one?
Max Freeman Project Lead at Epic Cash
I’d like to highlight the differences between Epic and the two highest-valued privacy coin projects, Monero and Zcash. XMR has always-on privacy like Epic does, but at a cost: Its blockchain is over 20x more data intensive than Epic, which limits its possibilities for scalability. Epic’s blockchain is small and light enough to run a full node on cell phones, something that is in our product road map. ZEC by comparison can’t run on low end devices because of its zero knowledge based approach, and only 1% of transactions are fully private. Epic is simply newer, more advanced technology than prior networks thanks to Mimblewimble
We will also add more algorithms to widen the range of hardware that can participate in mining. For example, cell phones and tablets based around ARM chips. Millions of people can mine Epic that can’t mine Bitcoin, and that will help grow the network rapidly.
There are some great short videos on our YouTube channel https://www.youtube.com/channel/UCQBFfksJlM97rgrplLRwNUg/videos
that explain why we believe we have created something truly special here.
Our core architecture derives from Grin, so we are fortunate to benefit on an ongoing basis from their considerable development efforts. We are focused on making our currency truly usable and widely available, beyond a store of value and becoming a true medium of exchange.
Yoga Dude PR&Marketing at Epic Cash
Well we all have our views, but in a nutshell, we offer things that were missing in the previous cryptos. We have sound fiscal emission schedule matching Bitcoin, but we are vastly more private and faster. Our blockchain is lighter than Bitcoin or Monero and our tech is more scalable. Also, we are unique in that we are mineable with CPUs and GPUs as well as ASICs, giving the broadest population the ability to mine Epic Cash. Plus, you can’t forget FUNGIBILITY 🙂 we are big on that — since you can’t have true privacy without fungibility.
Also, please understand, we have HUGE respect to all the cryptos that came before us, we learned a lot from them, and thanks to their mistakes we evolved.
Xenolink Advisor at Epic Cash
To add on, what also makes Epic Cash unique is the ability to decentralize the mining using a tri-algo model of Random X (CPU), Progpow (GPU), and Cuckoo (ASIC) for an ability to do hybrid mining. I believe this is an issue we can see today in Bitcoin having centralized mining and the average user has a costly barrier of entry.
To follow up on this one in my opinion one of the things we adopted that we have seen success for , in example Bitcoin and Monero, is a strong community driven coin. I believe having a community driven coin will provide a more organic atmosphere especially when starting with No ICO, or Premine with a fair distribution model for everyone.
CryptoDiffer team
Q3: What are the major milestones Epic Cash has achieved so far? Maybe you can share with us some exciting plans for future weeks/months?
Yoga Dude PR&Marketing at Epic Cash
Since we went live in September of 2019, we attracted a very large community of users, miners, investors and contributors from across the world. Epic Cash is a very international project with white papers translated into over 30 languages. We are very much a community driven project; this is very evident from our content and the amount of translations in our white papers and in our social media content.
We are constantly working on improving our usability, security and privacy, as well as getting our message and philosophy out into the world to achieve mass adoption. We have a lot of exciting plans for our project, the plan is to make Epic Cash into something that is More than Money.
You can tell I am the Marketing guy since my message is less about the actual tech and more about the usability and use cases for Epic Cash, I think our Team and Community have a great mix of technical, practical, social and fiscal experiences. Since we opened our YouTube channels content for community submissions, we have seen our content translated into Spanish, French, German, Polish, Chinese, Japanese, Arabic, Russian, and other languages
Max Freeman Project Lead at Epic Cash
Our future development roadmap will be published soon and includes 4 tracks:
Usability
Mining
Core Protocol
Ecosystem Development
Core Protocol
Epic Server 2.9.0 — this release improves the difficulty adjustment and is aimed at making block emission closer to the target 60 seconds, particularly reducing the incidence of extremely short and long blocks — Status: In Development (Testing) Anticipated Release: June 2020
Epic Server 3.0.0 — this completes the rebase to Grin 3.0.0 and serves as the prerequisite to some important functional building blocks for the future of the ecosystem. Specifically, sending via Tor (which eliminates the need to open ports), proof of payment (useful for certain dex applications e.g. Bisq), and our native mobile app. Status: In Development (Testing) Anticipated Release: Fall 2020
Non-Interactive Transactions — this will enhance usability by enabling “fire and forget” send-to-address functionality that users are accustomed to from most cryptocurrencies. Status: Drawing Board Anticipated Release: n/a
Scaling Options — when blocks start becoming full, how will we increase capacity? Two obvious options are increasing the block size, as well as a Lightning Network-style Layer 2 structure. Status: Drawing Board Anticipated Release: n/a
Confidential Assets — Similar to Raven, Tari, and Beam, the ability to create independently tradable assets that ride on the Epic Blockchain. Status: Drawing Board Anticipated Release: n/a
Usability
GUI Wallet 2.0 — Restore from seed words and various usability enhancements — Status: Needs Assessment Anticipated Release: Fall 2020
Mobile App — Native mobile experience for iOS and Android. Status: In Development (Testing) Anticipated Release: Winter 2020
Telegram Integration — Anonymous payments over the Telegram network, bot functionality for groups. Status: Drawing Board Anticipated Release: n/a
Mining
RandomX on ARM — Our 4th PoW algorithm, this will enable tablets, cell phones, and low power devices such as Raspberry Pi to participate in mining. Status: Needs Assessment Anticipated Release: n/a
The economics of mining Epic are extremely compelling for countries that have free or extremely cheap electricity, since anyone with an ordinary PC can mine. Individual people around the world can simply run the miner and earn meaningful money (imagine Venezuela for example), something that has not been possible since the very early days of Bitcoin.
Ecosystem Development
Atomic Swaps — Connecting Epic to other blockchains in a trustless way, starting with ETH so that Epic can trade on DeFi infrastructure such as Uniswap, Kyber, etc. Status: Drawing Board Anticipated Release: n/a
Xenolink Advisor at Epic Cash
From the Community aspect, we have been further developing our community international reach. We have been seeing an increase in interest from South America, China, Russia, Japan, Italy, and the Philippines. We are working on targeting more countries. We truly aim to be a decentralized project that is open to everyone worldwide.
CryptoDiffer team
Great, thank you for your answers, we now can move to community questions part!
Cryptodiffer Community
You have 3 mining algorithms, the question is: how do they not compete with each other? Is there any benefit of mining on the GPU and CPU if someone is mining on the ASIC?
Max Freeman Project Lead at Epic Cash
The block selection is deterministic, so that every 100 blocks, 60% are for RandomX (CPU), 38% for ProgPow (GPU), and 2% for Cuckoo (ASIC) — the policy is flexible so that we can have as many algorithms with any percentages we want. The goal is to make the most decentralized and resilient network possible, and with that in mind we are excited to work on enabling tablets and cell phones to mine, since that opens it up to millions of people that otherwise can’t take part.
Cryptodiffer Community
To Run a project smoothly, Funding is very important, From where does the Funding/revenue come from?
Xenolink Advisor at Epic Cash
Yes, early on this was realized and in order to scale a project funds are indeed needed. Epic Cash did not start with any funding and no ICO and was organically genesis mined with no pre-mine. Epic cash is also a nonprofit community driven project similar to Monero. There is no profit-driven entity in the picture. To overcome the revenue issue Epic Cash setup a development fund tax that decreases 1% every year until 2028 when Epic Cash reaches singularity with Bitcoin emissions. Currently it is at 7.77%. This will help support the scaling of the project.
Cryptodiffer Community
Hi! In your experience working also with MONERO can you please clarify which are those identified problems that EPIC CASH aims to develop and resolve? What’s the main advantage that EPIC CASH has over MONERO? Thank you!
Yoga Dude PR&Marketing at Epic Cash
First, I must admit that I am still a huge fan and HODLer of Monero. That said:
✅ our blockchain is MUCH lighter than Monero’s
✅ our transaction processing speed is much faster
✅ our address-less blockchain is more private
✅ Epic Cash can be mined with CPU (RandomX) GPU (ProgPow) and Cuckoo, whereas Monero migrated to RandomX and currently only mineable with CPU

  1. the feature ‘Cut Through’ deletes old data, how is it decided which data will be deletes, and what are the consequences of it for the platform and therefore the users?
  2. On your website I see links to download Epic wallet and mining software for Linux,Windows and MacOs, I am a user of android, is there a version for me, or does it have a release date?
Max Freeman Project Lead at Epic Cash
  1. This is one of the most exciting features of Mimblewimble, which is its extraordinary ability to compress blockchain data. In Bitcoin, the entire history of a coin must be replayed every time it is spent, and comprehensive details are permanently stored in the blockchain. Epic discards spent transaction inputs and consolidates outputs, storing neither addresses or amounts, only a tiny kernel to allow sender and receiver to prove their transaction.
  2. The Vitex mobile app is great for today, and we have a native mobile app for iOS and Android in the works as well.

$EPIC Have total Supply of 21,000,000 EPIC , is there any burning plan? Or Buyback program to maintain $EPIC price in the future?
Who is Epic Biggest competitors?
And what’s makes epic better than competitors?
Xenolink Advisor at Epic Cash
We respect the older generation coins like Bitcoin. But we have learned that the supply economics of Bitcoin is very sound. Until today we can witness how the Bitcoin is being adopted institutionally and by retail. We match the 21 million BTC supply economics because it is an inelastic fixed model which makes the long-term economics very sound. To have an elastic model of burning tokens or printing tokens will not have a solid economic future. Take for example the USD which is an inflating supply. In terms of competitors we look at everyone in crypto with respect and also learn from everyone. If we had to compare to other Mimblewimble tech coins, Grin is an inelastic forever inflating supply which in the long term is not sound economics. Beam however is an inelastic model but is formed as a corporation. The fair distribution is not there because of the permanent revenue model setup for them. Epic Cash a non-profit development tax fund model for scaling purposes that will disappear by 2028’s singularity.
Cryptodiffer Community
What your plans in place for global expansion, are you focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships?
Yoga Dude PR&Marketing at Epic Cash
Since we are a community project, we have many developers, in addition to the core team.
Our plans for Global expansion are simple — we have advocates in different regions addressing their audiences in their native languages. We are growing organically, by explaining our ideology and usability. The idea is to grow beyond needing a fiat bridge for crypto use, but to rather replace fiat with our borderless, private and fungible crypto so people can use it to get goods and services without using banks.
We are not limiting ourselves to one particular demographic — Epic Cash is a valid solution for the gamers, investors, techie and non techie people, and the unbanked.
Cryptodiffer Community
EPIC confidential coin! Did you have any problems with the regulators? And there will be no problems with listing on centralized exchanges?
Xenolink Advisor at Epic Cash
In terms of structure, we are carefully set up to minimize these concerns. Without a company or investors in the picture, and having raised no funds, there is little scope to attack in terms of securities laws. Bitcoin and Ethereum are widely acknowledged as acceptable, and we follow in their well-established footprints in that respect. Centralized exchanges already trade other privacy coins, so we don’t see this as much of an issue either. In general, decentralized p2p exchange options are more interesting than today’s centralized platforms. They are more censorship resistant, secure, and privacy-protecting. As the technology gets better, they should continue to gain market share and that’s why we’re proud to be partnered with Vitex, whose exchange and mobile app work very well.
Cryptodiffer Community
What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Max Freeman Project Lead at Epic Cash
Because our blockchain is so light (only 1.16gb currently, and grows very slowly) it is naturally well suited to become a decentralized mobile money standard because people can run a full node on their phone, guaranteeing the security of their funds. Scalability in Bitcoin requires complicated and compromised workarounds such as Lightning Network and light clients, and these problems are solved in Epic.
With our forthcoming Mobile Mining app, hundreds of millions of cell phones and tablets will be able to easily join the network. People can quickly and cheaply send money to one another, fulfilling the long-envisioned promise of P2P electronic cash.
As an investor, it’s important to ask a few key questions. Bitcoin Standard tokenomics of disinflation and a fixed supply are well proven over a decade now. We follow this model exactly, with a permanently synchronized supply from 2028, and 4 emission halvings from now until then, with our first one in about two weeks. Beyond that, we can apply some simple logical tests. What is more valuable, money that can only be used in some cases (censorable Bitcoin based on a lack of fungibility) or money that can be used universally? (fungible Epic based on always-on privacy by default). Epic is also poised to be a more decentralized and therefore resilient network because of wider participation in mining. Epic is designed to be Bitcoin++ Privacy, Fungibility, Scalability
Cryptodiffer Community
Q1. What are advantages for choosing three mining algorithms RandomX+, ProgPow and CuckAToo31+ ?
Q2. Beam and Grin use MimbleWimble protocol, so what are difference for Epic? All of you will be friends for partners or competitors?
Max Freeman Project Lead at Epic Cash
RandomX and ProgPow are designed to use the entirety of a CPU / GPU’s unique processing capabilities in a way that other types of hardware don’t work as well. You can run RandomX on a GPU but it doesn’t work nearly as well as a much cheaper CPU, for example. Cuckoo is a “memory hard” algorithm that widens the range of companies that can produce the hardware.
Grin and Beam are great projects and we’ve learned a lot from them. We inherited our first codebase from Grin’s excellent Rust design, which is a better language for community participation than C++ that Beam currently uses.
Functionally, Mimblewimble is similar across the 3 coins, with standard Confidential Transactions, CoinJoin, Dandelion++, Schnorr Signatures and other advanced features. Grin is primarily ASIC-targeted, Beam is GPU-targeted, and Epic is multi-hardware.
The biggest differences though are in tokenomics and project structure. Grin has permanent inflation of 60 coins per block with no halvings, which means steady erosion of value over time due to new supply pressure. It also lacks a steady funding model, making future development in jeopardy, particularly as the per coin price falls. Beam has a for-profit model with heavy early inflation and a high developer tax. Epic builds on the strengths of these earlier mimblewimble projects and addresses the parts that could be improved.
Cryptodiffer Community Some privacy coin has scalability issues! How Epic cash will solve scalability issues? Why you choose randomX consensus algorithem?
Xenolink Advisor at Epic Cash
Fungibility means that you can’t distinguish one unit of currency from another, in example Gold. Fungibility has recently become a hot issue as people have been noticing Bitcoins being locked up by exchanges which may of had a nefarious history which are called Tainted Coins. In example coins that have been involved in a hack, darknet market transactions, or even processing coin through a mixer. Today we can already see freshly mined Bitcoins being sold at a premium price to avoid the fungibility problem Bitcoin carries today. Bitcoin can be tracked by chainalysis and is not a fungible cryptocurrency. One of the features that Epic has is privacy with added fungibility, because of Mimblewimble technology, Epic has no addresses recorded and therefore nothing can be tracked by chainalysis. Below I provide a link of an example of what the lack of fungibility is resulting in today with Bitcoin. One of the reasons why we chose the Random X algo. is because of the easy barrier of entry and also to further decentralize the mining. Random X algo can be mined on old computers or laptops. We also have 2 other algos Progpow (GPU), and Cuckoo (ASIC) to create a wider decentralization of mining methods for Epic.
Cryptodiffer Community
I’m a newbie in crypto and blockchain so how will Epic Cash team target and educate people who don’t know about blockchain and crypto?
What is the uniqueness of Epic Cash that cannot be found in other project that´s been released so far ?
Yoga Dude Pr&Marketing at Epic Cash
Actually, while we have our white paper translated into over 30 languages, we are more focused on explaining our uses and advantages rather than cold specs. Our tech is solid, but we not get hung up on pure tech talk which most casual users do not need to or care to understand. As long as our fundamentals and tech are secure and user friendly our primary goal is to educate about use cases and market potential.
The uniqueness of Epic Cash is its amalgamation of “whats good” in other cryptos. We use Mimblewimble for privacy and anonymity. Our blockchain is much lighter than our competitors. We are the only Mimblewimble crypto to use a unique cocktail of mining algorithms allowing to be mined by casual miners with gaming rigs and laptops, while remaining friendly to GPU and CPU farmers.
The “uniqueness” is learning from the mistakes of those who came before us, we evolved and learned, which is why our privacy is better, we are faster, we are fungible, we offer diverse mining and so on. We are the best blend — thats powerful and unique
Cryptodiffer Community
Can you share EPIC’s vision for decentralized finance (DEFI)? What features do EPIC have to support DEFI?
Yoga Dude PR&Marketing at Epic Cash
We view Epic as ideally suited to be the decentralized digital reserve asset of the new Private Internet of Money that’s emerging. At a technology level, atomic swaps can be created to build liquidity bridges so that wrapped Epic tokens (like WBTC, WETH) can trade on other networks as ERC20, BEP2, NEP5, VIP180, Algorand and so on. There is more Bitcoin value locked on Ethereum than in Lightning Network, so we will similarly integrate Epic so that it can trade on networks such as Uniswap, Kyber, and so on.
Longer term, if there is market demand for it, thanks to Scriptless Script functionality our blockchain has, we can build “Confidential Assets” (which Raven, Tari, and Beam are all also working on) that enable people to create tokenized assets in a private way.

If you could choose one celebrity to promote Epic-cash, who that would be?
Max Freeman Project Lead at Epic Cash
I am a firm believer that the strength of the project lies in allowing community members to become their own celebrities, if their content is good enough the community will propel them to celebrity status. Organic celebrities with small but loyal following are vastly more beneficial than big name professional shills with inflated but non caring audiences.
I remember the early days of Apple when an enthusiastic dude named Guy Kawasaki became Apple Evangelist, he was literally going around stores that sold Apple and visited user groups and Evangelized his belief in Apple. This guy became a Legend and helped Apple become what it is today.
Epic Cash will have its OWN Celebrities

How does $EPIC solve scalability of transactions? Current blockchains face issues with scalability a lot, how does $EPIC creates a solution to it?
Xenolink Advisor at Epic Cash
Epic Cash is utilizing Mimblewimble technology. Besides the privacy & fungibility aspect of the tech. There is the scalability features of it. It is implemented into Epic by transaction cut-through. Which means it allows nodes to remove all intermediate transactions, thus significantly reducing the blockchain size without affecting its validation. Mimblewimble also does not use addresses like a BTC address, and amount of transactions are also not recorded. One problem Monero and Bitcoin are facing now is scalability. It is evident today that data is getting more expensive and that will be a problem in the long run for those coins. Epic is 90% lighter and more scalable compared to Monero and Bitcoin.
Cryptodiffer Community
what are the ways that Epic Cash generates profits/revenue to maintain your project and what is its revenue model ? How can it make benefit win-win to both invester and your project ?
Max Freeman Project Lead at Epic Cash
There is a block subsidy of 7.77% that declines 1.11% per year until 0, where it stays after that. As a nonprofit community effort, this extremely modest amount goes much further than in other projects, which often take 20, 30, even 50+ % of the coin supply. We believe that this ongoing funding model best aligns the long term incentives for all participants and balances the compromises between the ends of the centralized/decentralized spectrum of choices that any project must make.
Cryptodiffer Community
Q1 : What are your major goals to archive in the next 3–4 years?
Q2 : What are your plans to expand and gain more adoption?
Yoga Dude Pr&Marketing at Epic Cash
Max already talked about our technical plans and goals in his roadmap. Allow me to talk more about the non technical 😁
We are aiming for broader reach in the non technical more mainstream community — this is a big challenge but we believe it is doable. By offering simpler ways to mine Epic Cash (with smart phones for example), and by doing more education we will achieve the holy grail of crypto — moving past the fiat bridges and getting Epic Cash to be accepted as means of payment for goods and services. We will accomplish this by working with regional advocacy groups, community interaction, off-line promotional activities and diverse social media targeting.
Cryptodiffer Community
It seems to me that EpicCash will have its first Halving, right? Why a halving so soon?
Is a mobile version feasible?
Max Freeman Project Lead at Epic Cash
Our supply emission catches up to that of Bitcoin’s first 19 years after 8 years in Epic, so that requires more frequent halvings. Today’s block emission is 16, next up are 8, 4, 2, and then finally 0.15625. After that, the supply of Epic and that of BTC stay synchronized until maxing out at 21m coins in 2140.
Today we have a mobile wallet through the Vitex app, a native mobile wallet coming, and are working on mobile mining.
Cryptodiffer Community
What markets will you add after that?
Yoga Dude PR&Marketing at Epic Cash
Well, we are aiming to have ALL markets
Epic Cash in its final iteration will be usable by everyone everywhere regardless of their technical expertise. We are not limiting ourselves to the technocrats, one of our main goals is to help the billions of unbanked. We want everyone to be able to mine, buy, and most of all USE Epic Cash — gamers, farmers, soccer moms, students, retirees, everyone really — even bankers (well once we defeat the banking industry)
We will continue building on the multilingual diversity of our global community adding support and advocacy groups in more countries in more languages.
Epic Cash is More than Money and its for Everyone.
Cryptodiffer Community
Almost, all cryptocurrencies are decentralized & no-one knows who owns that cryptocurrencies ! then also, why Privacy is needed? hats the advantages of Private coins?
Max Freeman Project Lead at Epic Cash
With a public transparent blockchain such as Bitcoin, you are permanently posting a detailed history of your money movements open for anyone to see (not just legitimate authorities, either!) — It would be considered crazy to post your credit card or bank statements to Twitter, but that’s what is happening every time you send a transaction that is not private. This excellent video from community contributor Spencer Lambert https://www.youtube.com/watch?v=0blbfmvCq\_4 explains better than I can.
Privacy is not just for criminals, it’s for everyone. Do you want your landlord to increase the rent when he sees that you get a raise? Your insurance company to raise your healthcare costs because they see you buying too much ice cream? If you’re a business, do you want your employees to see how much money their coworkers make? Do you want your competitors to trace your supplier and customer relationships? Of course not. By privacy being default for everyone, cryptocurrency can be used in a much wider range of situations without unacceptable compromises.
Cryptodiffer Community
What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Xenolink Advisor at Epic Cash
Epic Cash can be used as a Private and Fungible store of value, medium of exchange, and unit of account. As Epic Cash grows and becomes adopted it can be compared to how Bitcoin and Monero is used and adopted as well. As Epic is adopted by the masses, it can be accepted as a medium of exchange for store owners and as fungible payments without the worry of having money that is tainted. Epic Cash as a store of value may be a good long term aspect of investment to consider. Epic Cash carries an inelastic fixed supply economic model of 21 million coins. There will be 5 halvings which this month of June will be our first halving of epic. From a block reward of 16 Epic reduced to 8. If we look at BTC’s price action and history of their halvings it has been proven and show that there has been an increase in value due to the scarcity and from halvings a reduction of # of BTC’s mined per block. An inelastic supply model like Bitcoin provides proof of the circulating supply compared to the total supply by the history of it’s Price action which is evident in long term charts since the birth of Bitcoin. EPIC Plans to have 5 halvings before the year 2028 to match the emissions of Bitcoin which we call the singularity event. Below is a chart displaying our halvings model approaching singularity. Once bitcoin and cryptocurrency becomes adopted mainstream, the fungibility problem will be more noticed by the general public. Privacy coins and the features of fungibility/scalability will most likely be sought over. Right now a majority of people believe that all cryptocurrency is fungible. However, that is not true. We can already see Chainalysis confirming that they can trace and track and even for other well-known privacy coins today such as Z-Cash.

  1. You aim to reach support from a global community, what are your plans to get spanish speakers involved into Epic Cash? And emerging markets like the african
  2. How am I secure I won’t be affected by receiving tainted money?
Max Freeman Project Lead at Epic Cash
Native speakers from our community are working to raise awareness in key markets such as mining in Argentina and Venezuela for Spanish (Roberto Navarro called Epic “the holy grail of cryptocurrency” and Ethiopia and certain North African countries that have the lowest electricity costs in the world. Remittances between USA and Latin American countries are expensive and slow, so Epic is also perfect for people to send money back home as well.

Do EPICs in 2020 focus more on research and coding, or on sales and implementation?
Yoga Dude PR&Marketing at Epic Cash
We will definitely continue to work on research and coding, with emphasis on improved accessibility (especially via smartphones) usability, security and privacy.
In terms of financial infrastructure will continuing to add exchanges both KYC and non KYC.
Big part of our plans is in ongoing Marketing and PR outreach. The idea is to make Epic Cash a viral sensation of sorts. If we can get Epic Cash adopters to spread the word and tell their family, coworkers and friends about Epic Cash — there will be no stopping us and to help that happen we have a growing army of content creators, and supporters.
Everyone with skin in the game gets the benefit of advancing the cause.
Folks also, this isn’t an answer to the question but an example of a real-world Epic Cash content —

I was watching some videos explaining how to send and receive transactions in EpicCash, which consists of ports and sending links, my question is why this is so, which, for now, looks complex?
Let’s talk about the economic model, can EpicCash comply with the concept of value reserve?
Max Freeman Project Lead at Epic Cash
In V3, which is coming later this summer, Epic can be sent over Tor, which eliminates this issue of port opening, even though using tools like ngrok.io, it’s not necessarily as painful as directly configuring the router ports. Early Lightning Network had this issue as well and it’s something we have a plan to address via research into non-interactive transactions. “Fire and Forget” payments to an address, as people are used to in Bitcoin, is coming to Epic and we’re excited to develop functionality that other advanced mimblewimble coins don’t yet have. We are committed to constant improvement in usability and utility, to make our money system the ease of use leader.
We are involved in the project (anyone can join the Freeman Family) because we believe that simply by choosing to use a form of money that better aligns with our ideals, that we can make a positive change in the world. Some of my thoughts about how I got involved are here: https://medium.com/epic-cash/the-freeman-family-e3b9c3b3f166
Max Freeman Project Lead at Epic Cash
Huge thanks to our friends Maks and Vladyslav, we welcome everyone to come say hi at one of our friendly communities. It is extremely early in this journey, our market cap is only 0.5m right now, whereas the 3 other mimblewimble coins are at $20m, $30m and $100m respectively. Epic is a historic opportunity to follow in the footsteps of legends such as Bitcoin and Monero, and we hope to become the first Top 5 privacy coin project.

The Economics of "ASICs" for RandomX

Cross posted from Monero
Regarding RandomX and ASICs, people seem to mis-understand the interaction between hardware/software, the costs of development/manufacture of world class semiconductors, and the economics of ASIC mining.
These on-chip, bare metal processing units that RandomX requires are highly advanced, and required to make chips "smart." An "ASIC" takes simple dumb functions and iterates them on bare silicon, rather than as a software abstraction (a layer higher) on top of the underlying hardware.
There are a few things that RandomX didn't include, meaning that a fully optimized "ASIC" processor could eliminate some unused logic units to make room for the others particular to RandomX. At most, the designers of RandomX estimate a 2x improvement over current CPUs.
2x. That's almost nothing when you consider the economics of what it takes to make one of these things. As someone who spent 5 years as a process engineer in a world class semicon fab, I can tell you the design, testing, manufacture and turnaround time for advanced CPUs is enormous. Nothing like dumb SHA256 ASICs or simple memory chips. You better be gettting a huge return on investment to go to all that trouble.
2x is nothing. Bitcoin ASICs arose because there was something on the order of 1000x speed advantage over GPUs. That's the kind of economics you need to recoup the costs involved. Not to mention that you are still competing against the ever progressing AMD and Intel advancements (and probably ARM and RISC-V soon enough). Bitmain has very little competition. They have the patents and the process for new ASICs.
So no, it's unlikely, for years, that anyone will develop an economically viable "ASIC" (lol) for RandomX.
What we might see are CPU manufacturers use RandomX as a benchmark for their new units, since you will have the promise of a sort of "rebate" by mining Monero. In fact that could be an awesome marketing opportunity for Monero.

Leads you to a comprehensive understanding of Forbes

https://preview.redd.it/1dra1br1xu351.png?width=740&format=png&auto=webp&s=925b38326cb8aa4f4b2863670ada61005ee72c4c
What is the hottest blockchain project in 2020?
Besides GFS, GFS is still GFS in my mind! GFS currency - the only token of Forbes cross chain blockchain!
Forbes is the latest generation of blockchain, which can be said to be a new blockchain mode, or it is not a pure blockchain project. As we all know, in the era of blockchain 1.0, the bitcoin of Nakamoto brings decentralized distributed bookkeeping book, which enables human beings to have just assets for the first time; in the era of 2.0, the Ethereum smart contract created by V God makes the blockchain have divergent applications; in the era of 3.0, innovation public chains such as EOS make the application of blockchain easier to land. It will open Forbes in the era of blockchain 4.0 and create a distributed financial era of "ten thousand chain interconnection". My feeling is that Forbes is going to overthrow the traditional Internet and the classic blockchain, and reshape a financial world built directly on the blockchain.
The most classic sentence on the Internet is: change your life, but it has nothing to do with you.
In this way, Forbes uses the philosophy of blockchain and further technology to redo blockchain and bring blockchain to a new dimension. Today's bitcoin looks like a monument and a myth, but Forbes is using its cross chain technology and financial deployment to gently reinterpret the blockchain.
Next, I will expand what you are concerned about and what I see in the form of Q & A:
1. Is it investment or speculation to participate in Forbes?
Although we do not exclude speculation, there is no doubt that participating in Forbes is one of the best investment behaviors in 2020, no less than investing in bitcoin in 2013 and Ethereum in 2016. Forbes is a pure technology project, with no messy black box operation. As Forbes early deployed the ore field to facilitate the construction of cross chain system, early users can rent the Forbes BTC miner loaded with self-developed bitcoin ASIC chips by way of mortgage, with the strongest configuration on the ground. Moreover, in the process of mining, the early nodes do not even need to pay a penny, only mortgage deposit can deploy the physical miner. The income obtained can also participate in the early stage node plan carried out by Dao organization, and part of the income can be converted into GFS through Forbes wallet.
And the deposit is not a routine, all the mortgage deposits will be locked in the chain. With the shortening of the lease term, each day will be returned to the user's wallet through the "deposit smart contract", without any centralized individual and organization participation in the whole process. In this way, it is equivalent to zero risk investment! After all, Forbes, with its cryptology and open source spirit, is inherently powerful. What Forbes wants to change is the life of centralization!
And then there's no more. Jane is not simple.
2. Why do you like Forbes?
Very simple, blockchain 4.0
First of all, let's not talk about anything. Forbes has solved a problem - mining hegemony.
In the past, blockchain seems that nodes can enter and leave freely, but in fact, it needs a huge threshold to become nodes and obtain mining rewards. Whether it's bitcoin, you need to buy very expensive and complex mining equipment (ASIC miner), or EOS, Tron and other POS projects, and you need to hold a large number of coins to be elected as nodes. All in all, most of the current blockchain systems need very high mining costs, which in essence violates the principle of zhongbencong's blockchain design.
The powerful thing about Forbes is that it creatively constructs dpoc as a consensus mechanism of trunk chain (main chain). Dpoc is a kind of common understanding of POC. There is no big deployment threshold for mining with hard disk miner. As a result of the consensus between Forbes blockchain Multi Chain Design and dpoc, all mining machines that do not have the relay chain node selected can pack the interaction information between the parallel chain and the relay chain, and can also obtain the block reward. In essence, such a design realizes Zhongben Cong's idea that everyone can dig. Let alone Forbes to build a mine pool, to build the strongest mining machine that can dig out the Forbes token GFS.
With this in mind, which blockchain product can match.
Layout of Forbes
The vision of Forbes: to build the most universal distributed financial system in the world, driven by Forbes, the most widely used cross chain system in the world.
I saw two key words: cross chain, distributed Finance
Cross chain is the most urgent problem in current blockchain ecology. In the past 10 years, various blockchain systems have been deepening in security and performance, but no progress has been made in chain and chain scalability. As you can see, the chain and the chain is an island. Can EOS players and wave players break the bond?
In the human financial life, transaction, loan, personal credit, supply chain finance, stock, commodity... They are directly full of interaction and connection. It can be said that human beings are dealing with all kinds of transactions all the time. Can the isolated blockchain really solve the problem?
Forbes is born to be a global distributed financial system and truly a financial ecosystem. Imagine what a change it would be if you could smoothly carry out blockchain financial activities with foreign small partners. This pattern is too big for me to say. But please believe that if this is done, it can be described as a complete disaster.

https://preview.redd.it/ee15vfv8xu351.png?width=1450&format=png&auto=webp&s=b36e2aa2548e0320b127d30e67d28511a666b30b
3. Is it better to mine or invite new people?
Since this is my experience interpretation, I think: invite, boldly invite new people. Every time you invite one, you add a certain amount of calculation power. It's good to mine in Buddhism, but if you can participate in the birth of a great project, you can get more profits. Why not?
Let's take a different perspective: now that you recognize Forbes, you recognize its value. Or you're not going to dig, are you! So, why can't we add more yards! Since we are trying to change our destiny, this is the highest lever. If it does, which lever can be bigger than Forbes!
So, invest money or energy, and do what you can.
4. Do I want to join the Forbes pool project?
Do you want to do it.
They all recognize the value, so they can download the application directly.
My original intention:
First of all, GFS coin is a new mining model - POC hard disk mining that "everyone can dig, everyone can benefit". It avoids pow (proof of work workload) which is a large power consumption mode. In the initial stage of the main network online, Forbes opened the mine pool plan, leasing the mine machine at zero cost, becoming the earliest node of blockchain 4.0 representing the project, and obtaining the maximum benefit. Why not? You know, GFS production is also halved in four years. To dig now is to dig bitcoin before 2013, without cost.
Secondly, in this stage, we can also increase the number of invited nodes. After the completion of the mining pool plan, we can only rely on hard indicators to increase the computing power. Now we can also rely on our efforts to get more profits. Therefore, in the face of equal opportunities for all, this is a great opportunity to take the initiative. Still hesitant?
5. Blockchain is my knowledge blind area. What can I do if I don't understand cross chain knowledge?
First of all, you have to ask you, this is the excuse you don't want to get wealth?
Not only Forbes is your knowledge blind area, but blockchain is a knowledge blind area for ordinary people. However, you should know that in 2020, the State advocates blockchain, the central bank DCEP has been put into trial operation, and blockchain has been applied in many aspects. Are you still in your blind spot?
Of course, it's not good to pull the national flag. Let's talk about something practical. Opportunity always appears in new things. Ask, what's the matter with you, a solidified model? You have money or connections. I believe that choice is more important than effort. A road, if we choose the wrong direction at the beginning, the harder we work, the farther away we are from our goal.
Therefore, the knowledge blind spot is not my problem, but whether you have a heart willing to contact new things!
Among the miners I know, there is a 67 year old elder brother who has been a soldier, a factory, a traditional businessman and a cell phone. Do you still have his blind spot?
6. Will Forbes succeed?
To be honest, I don't know. But I know that it is the blockchain project that I hope to reach the most in 2020. For details, please refer to the second question, why I like Forbes. If you really question Forbes, you can choose to only participate in the "miner Alliance Plan" and choose to mine at zero cost. No matter how the Forbes project progresses, you can get the benefit of mining without cost. Why not? Besides, when the Forbes project is really implemented, you can decide whether to invest in GFS. I'm sure you will have your own judgment at that time.
7. What is the most important thing to dig GFS?
Insist, insist, or insist.
We must make full use of our efforts in the earliest planning activities of the mine pool. After all, mining at zero cost + inviting to increase the calculation power and increase the support in the wet season. At this stage, we must dig more coins and exchange more for GFS. Maybe the reward coins you dig out in three months can't be found in a year after you try to buy hard disk mining machines for nodes.

8. There are so many people who rent mining machines first. Do I have a chance?
People die more than people, and goods are thrown away more than goods. Don't compare with others, just be yourself.
God said, I can fulfill your one wish, but I will give you twice as many neighbors.
You will choose 10 million positive choices,
Or one less arm in the dark?
Mining is like this. Those old miners are your neighbors. Dare to own 10 million good, do not think about neighbors than you 10 million. Is that right? And when there are 10000 GFS, do you still want someone to have 100 more than you?
9. How much is GFS worth?
To be honest, I don't know. The number of GFS is 21 million bitcoin, and the price of bitcoin is about 60000 yuan. The GFS main network has just been launched. In some markets, its price has increased more than 10 times in five days, far exceeding the price of bitcoin before the half reduction. The miners who rent mining machines in advance are blessed.
As for the future, with the start of the implementation of blockchain financial facilities this year, GFS must be just the beginning. Where is the top? We witnessed it together.
10. Which do I want, kusd or usdt?
For now, it doesn't matter which one you use. Although usdt has a lot of potential risks, there are still many people using it. However, we all know that it will have a thunderstorm sooner or later.
As a cross chain gold stable currency, when cross chain finance begins to integrate into public life, kusd will show its power, which is better than issuing a usdt once in a chain. Moreover, more than 95% of the value of each kusd is based on gold, which can be exchanged by major gold exchanges in the world. The stability of gold. Have you seen it clearly in this epidemic? This is beyond the dollar.

Transcript of discussion between an ASIC designer and several proof-of-work designers from #monero-pow channel on Freenode this morning

[08:07:01] lukminer contains precompiled cn/r math sequences for some blocks: https://lukminer.org/2019/03/09/oh-kay-v4r-here-we-come/
[08:07:11] try that with RandomX :P
[08:09:00] tevador: are you ready for some RandomX feedback? it looks like the CNv4 is slowly stabilizing, hashrate comes down...
[08:09:07] how does it even make sense to precompile it?
[08:09:14] mine 1% faster for 2 minutes?
[08:09:35] naturally we think the entire asic-resistance strategy is doomed to fail :) but that's a high-level thing, who knows. people may think it's great.
[08:09:49] about RandomX: looks like the cache size was chosen to make it GPU-hard
[08:09:56] looking forward to more docs
[08:11:38] after initial skimming, I would think it's possible to make a 10x asic for RandomX. But at least for us, we will only make an ASIC if there is not a total ASIC hostility there in the first place. That's better for the secret miners then.
[08:13:12] What I propose is this: we are working on an Ethash ASIC right now, and once we have that working, we would invite tevador or whoever wants to come to HK/Shenzhen and we walk you guys through how we would make a RandomX ASIC. You can then process this input in any way you like. Something like that.
[08:13:49] unless asics (or other accelerators) re-emerge on XMR faster than expected, it looks like there is a little bit of time before RandomX rollout
[08:14:22] 10x in what measure? $/hash or watt/hash?
[08:14:46] watt/hash
[08:15:19] so you can make 10 times more efficient double precisio FPU?
[08:16:02] like I said let's try to be productive. You are having me here, let's work together!
[08:16:15] continue with RandomX, publish more docs. that's always helpful.
[08:16:37] I'm trying to understand how it's possible at all. Why AMD/Intel are so inefficient at running FP calculations?
[08:18:05] midipoet ([email protected]/web/irccloud.com/x-vszshqqxwybvtsjm) has joined #monero-pow
[08:18:17] hardware development works the other way round. We start with 1) math then 2) optimization priority 3) hw/sw boundary 4) IP selection 5) physical implementation
[08:22:32] This still doesn't explain at which point you get 10x
[08:23:07] Weren't you the ones claiming "We can accelerate ProgPoW by a factor of 3x to 8x." ? I find it hard to believe too.
[08:30:20] sure
[08:30:26] so my idea: first we finish our current chip
[08:30:35] from simulation to silicon :)
[08:30:40] we love this stuff... we do it anyway
[08:30:59] now we have a communication channel, and we don't call each other names immediately anymore: big progress!
[08:31:06] you know, we russians have a saying "it was smooth on paper, but they forgot about ravines"
[08:31:12] So I need a bit more details
[08:31:16] ha ha. good!
[08:31:31] that's why I want to avoid to just make claims
[08:31:34] let's work
[08:31:40] RandomX comes in Sep/Oct, right?
[08:31:45] Maybe
[08:32:20] We need to audit it first
[08:32:31] ok
[08:32:59] we don't make chips to prove sw devs that their assumptions about hardware are wrong. especially not if these guys then promptly hardfork and move to the next wrong assumption :)
[08:33:10] from the outside, this only means that hw & sw are devaluing each other
[08:33:24] neither of us should do this
[08:33:47] we are making chips that can hopefully accelerate more crypto ops in the future
[08:33:52] signing, verifying, proving, etc.
[08:34:02] PoW is just a feature like others
[08:34:18] sech1: is it easy for you to come to Hong Kong? (visa-wise)
[08:34:20] or difficult?
[08:34:33] or are you there sometimes?
[08:34:41] It's kind of far away
[08:35:13] we are looking forward to more RandomX docs. that's the first step.
[08:35:31] I want to avoid that we have some meme "Linzhi says they can accelerate XYZ by factor x" .... "ha ha ha"
[08:35:37] right? we don't want that :)
[08:35:39] doc is almost finished
[08:35:40] What docs do you need? It's described pretty good
[08:35:41] so I better say nothing now
[08:35:50] we focus on our Ethash chip
[08:36:05] then based on that, we are happy to walk interested people through the design and what else it can do
[08:36:22] that's a better approach from my view than making claims that are laughed away (rightfully so, because no silicon...)
[08:36:37] ethash ASIC is basically a glorified memory controller
[08:36:39] sech1: tevador said something more is coming (he just did it again)
[08:37:03] yes, some parts of RandomX are not described well
[08:37:10] like dataset access logic
[08:37:37] RandomX looks like progpow for CPU
[08:37:54] yes
[08:38:03] it is designed to reflect CPU
[08:38:34] so any ASIC for it = CPU in essence
[08:39:04] of course there are still some things in regular CPU that can be thrown away for RandomX
[08:40:20] uncore parts are not used, but those will use very little power
[08:40:37] except for memory controller
[08:41:09] I'm just surprised sometimes, ok? let me ask: have you designed or taped out an asic before? isn't it risky to make assumptions about things that are largely unknown?
[08:41:23] I would worry
[08:41:31] that I get something wrong...
[08:41:44] but I also worry like crazy that CNv4 will blow up, where you guys seem to be relaxed
[08:42:06] I didn't want to bring up anything RandomX because CNv4 is such a nailbiter... :)
[08:42:15] how do you guys know you don't have asics in a week or two?
[08:42:38] we don't have experience with ASIC design, but RandomX is simply designed to exactly fit CPU capabilities, which is the best you can do anyways
[08:43:09] similar as ProgPoW did with GPUs
[08:43:14] some people say they want to do asic-resistance only until the vast majority of coins has been issued
[08:43:21] that's at least reasonable
[08:43:43] yeah but progpow totally will not work as advertised :)
[08:44:08] yeah, I've seen that comment about progpow a few times already
[08:44:11] which is no surprise if you know it's just a random sales story to sell a few more GPUs
[08:44:13] RandomX is not permanent, we are expecting to switch to ASIC friendly in a few years if possible
[08:44:18] yes
[08:44:21] that makes sense
[08:44:40] linzhi-sonia: how so? will it break or will it be asic-able with decent performance gains?
[08:44:41] are you happy with CNv4 so far?
[08:45:10] ah, long story. progpow is a masterpiece of deception, let's not get into it here.
[08:45:21] if you know chip marketing it makes more sense
[08:45:24] linzhi-sonia: So far? lol! a bit early to tell, don't you think?
[08:45:35] the diff is coming down
[08:45:41] first few hours looked scary
[08:45:43] I remain skeptical: I only see ASICs being reasonable if they are already as ubiquitous as smartphones
[08:45:46] yes, so far so good
[08:46:01] we kbew the diff would not come down ubtil affter block 75
[08:46:10] yes
[08:46:22] but first few hours it looks like only 5% hashrate left
[08:46:27] looked
[08:46:29] now it's better
[08:46:51] the next worry is: when will "unexplainable" hashrate come back?
[08:47:00] you hope 2-3 months? more?
[08:47:05] so give it another couple of days. will probably overshoot to the downside, and then rise a bit as miners get updated and return
[08:47:22] 3 months minimum turnaround, yes
[08:47:28] nah
[08:47:36] don't underestimate asicmakers :)
[08:47:54] you guys don't get #1 priority on chip fabs
[08:47:56] 3 months = 90 days. do you know what is happening in those 90 days exactly? I'm pretty sure you don't. same thing as before.
[08:48:13] we don't do any secret chips btw
[08:48:21] 3 months assumes they had a complete design ready to go, and added the last minute change in 1 day
[08:48:24] do you know who is behind the hashrate that is now bricked?
[08:48:27] innosilicon?
[08:48:34] hyc: no no, and no. :)
[08:48:44] hyc: have you designed or taped out a chip before?
[08:48:51] yes, many years ago
[08:49:10] then you should know that 90 days is not a fixed number
[08:49:35] sure, but like I said, other makers have greater demand
[08:49:35] especially not if you can prepare, if you just have to modify something, or you have more programmability in the chip than some people assume
[08:50:07] we are chipmakers, we would never dare to do what you guys are doing with CNv4 :) but maybe that just means you are cooler!
[08:50:07] and yes, programmability makes some aspect of turnaround easier
[08:50:10] all fine
[08:50:10] I hope it works!
[08:50:28] do you know who is behind the hashrate that is now bricked?
[08:50:29] inno?
[08:50:41] we suspect so, but have no evidence
[08:50:44] maybe we can try to find them, but we cannot spend too much time on this
[08:50:53] it's probably not so much of a secret
[08:51:01] why should it be, right?
[08:51:10] devs want this cat-and-mouse game? devs get it...
[08:51:35] there was one leak saying it's innosilicon
[08:51:36] so you think 3 months, ok
[08:51:43] inno is cool
[08:51:46] good team
[08:51:49] IP design house
[08:51:54] in Wuhan
[08:52:06] they send their people to conferences with fake biz cards :)
[08:52:19] pretending to be other companies?
[08:52:26] sure
[08:52:28] ha ha
[08:52:39] so when we see them, we look at whatever card they carry and laugh :)
[08:52:52] they are perfectly suited for secret mining games
[08:52:59] they made at most $6 million in 2 months of mining, so I wonder if it was worth it
[08:53:10] yeah. no way to know
[08:53:15] but it's good that you calculate!
[08:53:24] this is all about cost/benefit
[08:53:25] then you also understand - imagine the value of XMR goes up 5x, 10x
[08:53:34] that whole "asic resistance" thing will come down like a house of cards
[08:53:41] I would imagine they sell immediately
[08:53:53] the investor may fully understand the risk
[08:53:57] the buyer
[08:54:13] it's not healthy, but that's another discussion
[08:54:23] so mid-June
[08:54:27] let's see
[08:54:49] I would be susprised if CNv4 ASICs show up at all
[08:54:56] surprised*
[08:54:56] why?
[08:55:05] is only an economic question
[08:55:12] yeah should be interesting. FPGAs will be near their limits as well
[08:55:16] unless XMR goes up a lot
[08:55:19] no, not *only*. it's also a technology question
[08:55:44] you believe CNv4 is "asic resistant"? which feature?
[08:55:53] it's not
[08:55:59] cnv4 = Rabdomx ?
[08:56:03] no
[08:56:07] cnv4=cryptinight/r
[08:56:11] ah
[08:56:18] CNv4 is the one we have now, I think
[08:56:21] since yesterday
[08:56:30] it's plenty enough resistant for current XMR price
[08:56:45] that may be, yes!
[08:56:55] I look at daily payouts. XMR = ca. 100k USD / day
[08:57:03] it can hold until October, but it's not asic resistant
[08:57:23] well, last 24h only 22,442 USD :)
[08:57:32] I think 80 h/s per watt ASICs are possible for CNv4
[08:57:38] linzhi-sonia where do you produce your chips? TSMC?
[08:57:44] I'm cruious how you would expect to build a randomX ASIC that outperforms ARM cores for efficiency, or Intel cores for raw speed
[08:57:48] curious
[08:58:01] yes, tsmc
[08:58:21] Our team did the world's first bitcoin asic, Avalon
[08:58:25] and upcoming 2nd gen Ryzens (64-core EPYC) will be a blast at RandomX
[08:58:28] designed and manufactured
[08:58:53] still being marketed?
[08:59:03] linzhi-sonia: do you understand what xmr wants to achieve, community-wise?
[08:59:14] Avalon? as part of Canaan Creative, yes I think so.
[08:59:25] there's not much interesting oing on in SHA256
[08:59:29] Inge-: I would think so, but please speak
[08:59:32] hyc: yes
[09:00:28] linzhi-sonia: i am curious to hear your thoughts. I am fairly new to this space myself...
[09:00:51] oh
[09:00:56] we are grandpas, and grandmas
[09:01:36] yet I have no problem understanding why ASICS are currently reviled.
[09:01:48] xmr's main differentiators to, let's say btc, are anonymity and fungibility
[09:01:58] I find the client terribly slow btw
[09:02:21] and I think the asic-forking since last may is wrong, doesn't create value and doesn't help with the project objectives
[09:02:25] which "the client" ?
[09:02:52] Monero GUI client maybe
[09:03:12] MacOS, yes
[09:03:28] What exactly is slow?
[09:03:30] linzhi-sonia: I run my own node, and use the CLI and Monerujo. Have not had issues.
[09:03:49] staying in sync
[09:03:49] linzhi-sonia: decentralization is also a key principle
[09:03:56] one that Bitcoin has failed to maintain
[09:04:39] hmm
[09:05:00] looks fairly decentralized to me. decentralization is the result of 3 goals imo: resilient, trustless, permissionless
[09:05:28] don't ask a hardware maker about physical decentralization. that's too ideological. we focus on logical decentralization.
[09:06:11] physical decentralization is important. with bulk of bitnoin mining centered on Chinese hydroelectric dams
[09:06:19] have you thought about including block data in the PoW?
[09:06:41] yes, of course.
[09:07:39] is that already in an algo?
[09:08:10] hyc: about "centered on chinese hydro" - what is your source? the best paper I know is this: https://coinshares.co.uk/wp-content/uploads/2018/11/Mining-Whitepaper-Final.pdf
[09:09:01] linzhi-sonia: do you mine on your ASICs before you sell them?
[09:09:13] besides testing of course
[09:09:45] that paper puts Chinese btc miners at 60% max
[09:10:05] tevador: I think everybody learned that that is not healthy long-term!
[09:10:16] because it gives the chipmaker a cost advantage over its own customers
[09:10:33] and cost advantage leads to centralization (physical and logical)
[09:10:51] you guys should know who finances progpow and why :)
[09:11:05] but let's not get into this, ha ha. want to keep the channel civilized. right OhGodAGirl ? :)
[09:11:34] tevador: so the answer is no! 100% and definitely no
[09:11:54] that "self-mining" disease was one of the problems we have now with asics, and their bad reputation (rightfully so)
[09:13:08] I plan to write a nice short 2-page paper or so on our chip design process. maybe it's interesting to some people here.
[09:13:15] basically the 5 steps I mentioned before, from math to physical
[09:13:32] linzhi-sonia: the paper you linked puts 48% of bitcoin mining in Sichuan. the total in China is much more than 60%
[09:13:38] need to run it by a few people to fix bugs, will post it here when published
[09:14:06] hyc: ok! I am just sharing the "best" document I know today. it definitely may be wrong and there may be a better one now.
[09:14:18] hyc: if you see some reports, please share
[09:14:51] hey I am really curious about this: where is a PoW algo that puts block data into the PoW?
[09:15:02] the previous paper I read is from here http://hackingdistributed.com/2018/01/15/decentralization-bitcoin-ethereum/
[09:15:38] hyc: you said that already exists? (block data in PoW)
[09:15:45] it would make verification harder
[09:15:49] linzhi-sonia: https://the-eye.eu/public/Books/campdivision.com/PDF/Computers%20General/Privacy/bitcoin/meh/hashimoto.pdf
[09:15:51] but for chips it would be interesting
[09:15:52] we discussed the possibility about a year ago https://www.reddit.com/Monero/comments/8bshrx/what_we_need_to_know_about_proof_of_work_pow/
[09:16:05] oh good links! thanks! need to read...
[09:16:06] I think that paper by dryja was original
[09:17:53] since we have a nice flow - second question I'm very curious about: has anyone thought about in-protocol rewards for other functions?
[09:18:55] we've discussed micropayments for wallets to use remote nodes
[09:18:55] you know there is a lot of work in other coins about STARK provers, zero-knowledge, etc. many of those things very compute intense, or need to be outsourced to a service (zether). For chipmakers, in-protocol rewards create an economic incentive to accelerate those things.
[09:19:50] whenever there is an in-protocol reward, you may get the power of ASICs doing something you actually want to happen
[09:19:52] it would be nice if there was some economic reward for running a fullnode, but no one has come up with much more than that afaik
[09:19:54] instead of fighting them off
[09:20:29] you need to use asics, not fight them. that's an obvious thing to say for an asicmaker...
[09:20:41] in-protocol rewards can be very powerful
[09:20:50] like I said before - unless the ASICs are so useful they're embedded in every smartphone, I dont see them being a positive for decentralization
[09:21:17] if they're a separate product, the average consumer is not going to buy them
[09:21:20] now I was talking about speedup of verifying, signing, proving, etc.
[09:21:23] they won't even know what they are
[09:22:07] if anybody wants to talk about or design in-protocol rewards, please come talk to us
[09:22:08] the average consumer also doesn't use general purpose hardware to secure blockchains either
[09:22:14] not just for PoW, in fact *NOT* for PoW
[09:22:32] it requires sw/hw co-design
[09:23:10] we are in long-term discussions/collaboration over this with Ethereum, Bitcoin Cash. just talk right now.
[09:23:16] this was recently published though suggesting more uptake though I guess https://btcmanager.com/college-students-are-the-second-biggest-miners-of-cryptocurrency/
[09:23:29] I find it pretty hard to believe their numbers
[09:24:03] well
[09:24:09] sorry, original article: https://www.pcmag.com/news/366952/college-kids-are-using-campus-electricity-to-mine-crypto
[09:24:11] just talk, no? rumors
[09:24:18] college students are already more educated than the average consumer
[09:24:29] we are not seeing many such customers anymore
[09:24:30] it's data from cisco monitoring network traffic
[09:24:33] and they're always looking for free money
[09:24:48] of course anyone with "free" electricity is inclined to do it
[09:24:57] but look at the rates, cannot make much money
[09:26:06] Ethereum is a bloated collection of bugs wrapped in a UI. I suppose they need all the help they can get
[09:26:29] Bitcoin Cash ... just another get rich quick scheme
[09:26:38] hmm :)
[09:26:51] I'll give it back to you, ok? ha ha. arrogance comes before the fall...
[09:27:17] maye we should have a little fun with CNv4 mining :)
[09:27:25] ;)
[09:27:38] come on. anyone who has watched their track record... $75M lost in ETH at DAO hack
[09:27:50] every smart contract that comes along is just waiting for another hack
[09:27:58] I just wanted to throw out the "in-protocol reward" thing, maybe someone sees the idea and wants to cowork. maybe not. maybe it's a stupid idea.
[09:29:18] linzhi-sonia: any thoughts on CN-GPU?
[09:29:55] CN-GPU has one positive aspect - it wastes chip area to implement all 18 hash algorithms
[09:30:19] you will always hear roughly the same feedback from me:
[09:30:52] "This algorithm very different, it heavy use floating point operations to hurt FPGAs and general purpose CPUs"
[09:30:56] the problem is, if it's profitable for people to buy ASIC miners and mine, it's always more profitable for the manufacturer to not sell and mine themselves
[09:31:02] "hurt"
[09:31:07] what is the point of this?
[09:31:15] it totally doesn't work
[09:31:24] you are hurting noone, just demonstrating lack of ability to think
[09:31:41] what is better: algo designed for chip, or chip designed for algo?
[09:31:43] fireice does it on daily basis, CN-GPU is a joke
[09:31:53] tevador: that's not really true, especially in a market with such large price fluctuations as cryptocurrency
[09:32:12] it's far less risky to sell miners than mine with them and pray that price doesn't crash for next six months
[09:32:14] I think it's great that crypto has a nice group of asicmakers now, hw & sw will cowork well
[09:32:36] jwinterm yes, that's why they premine them and sell after
[09:32:41] PoW is about being thermodynamically and cryptographically provable
[09:32:45] premining with them is taking on that risk
[09:32:49] not "fork when we think there are asics"
[09:32:51] business is about risk minimization
[09:32:54] that's just fear-driven
[09:33:05] Inge-: that's roughly the feedback
[09:33:24] I'm not saying it hasn't happened, but I think it's not so simple as saying "it always happens"
[09:34:00] jwinterm: it has certainly happened on BTC. and also on XMR.
[09:34:19] ironically, please think about it: these kinds of algos indeed prove the limits of the chips they were designed for. but they don't prove that you cannot implement the same algo differently! cannot!
[09:34:26] Risk minimization is not starting a business at all.
[09:34:34] proof-of-gpu-limit. proof-of-cpu-limit.
[09:34:37] imagine you have a money printing machine, would you sell it?
[09:34:39] proves nothing for an ASIC :)
[09:35:05] linzhi-sonia: thanks. I dont think anyone believes you can't make a more efficient cn-gpu asic than a gpu - but that it would not be orders of magnitude faster...
[09:35:24] ok
[09:35:44] like I say. these algos are, that's really ironic, designed to prove the limitatios of a particular chip in mind of the designer
[09:35:50] exactly the wrong way round :)
[09:36:16] like the cache size in RandomX :)
[09:36:18] beautiful
[09:36:29] someone looked at GPU designs
[09:37:31] linzhi-sonia can you elaborate? Cache size in RandomX was selected to fit CPU cache
[09:37:52] yes
[09:38:03] too large for GPU
[09:38:11] as I said, we are designing the algorithm to exactly fit CPU capabilities, I do not claim an ASIC cannot be more efficient
[09:38:16] ok!
[09:38:29] when will you do the audit?
[09:38:35] will the results be published in a document or so?
[09:38:37] I claim that single-chip ASIC is not viable, though
[09:39:06] you guys are brave, noone disputes that. 3 anti-asic hardforks now!
[09:39:18] 4th one coming
[09:39:31] 3 forks were done not only for this
[09:39:38] they had scheduled updates in the first place
[09:48:10] Monero is the #1 anti-asic fighter
[09:48:25] Monero is #1 for a lot of reasons ;)
[09:48:40] It's the coin with the most hycs.
[09:48:55] mooooo
[09:59:06] sneaky integer overflow, bug squished
[10:38:00] p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has joined #monero-pow
[11:10:53] The convo here is wild
[11:12:29] it's like geo-politics at the intersection of software and hardware manufacturing for thermoeconomic value.
[11:13:05] ..and on a Sunday.
[11:15:43] midipoet: hw and sw should work together and stop silly games to devalue each other. to outsiders this is totally not attractive.
[11:16:07] I appreciate the positive energy here to try to listen, learn, understand.
[11:16:10] that's a start
[11:16:48] <-- p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has quit (Quit: Leaving)
[11:16:54] we won't do silly mining against xmr "community" wishes, but not because we couldn'd do it, but because it's the wrong direction in the long run, for both sides
[11:18:57] linzhi-sonia: I agree to some extent. Though, in reality, there will always be divergence between social worlds. Not every body has the same vision of the future. Reaching societal consensus on reality tomorrow is not always easy
[11:20:25] absolutely. especially at a time when there is so much profit to be made from divisiveness.
[11:20:37] someone will want to make that profit, for sure
[11:24:32] Yes. Money distorts.
[11:24:47] Or wealth...one of the two
[11:26:35] Too much physical money will distort rays of light passing close to it indeed.
