Newbie Help

So I'm getting an RTX 3080 from Nvidia and that has a hashrate of 75 MH/s but on eBay how come I can buy a USB Bitcoin Miner ( GekkoScience Newpac USB Bitcoin Miner ) for £55 and get 28 GH/s which equates to £450 per day in terms of etherium currency (at the current price). I'm pretty sure this is too good to be true? Am I right? There are several others similar to this such as renting a 250 TH/s mining setup for 24 hours for only £40 but with the 250 TH/s you could make £4.6k per day. I am very confused...

Filecoin | Development Status and Mining Progress

Author: Gamals Ahmed, CoinEx Business Ambassador
https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704
A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.

[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.
Electricity consumed by bitcoin network has been constantly and noticeably increasing. During the past years the consumption reached such big a scale, that it can be compared to electricity consumption of some countries, according to BlockchainAnalytics.pro research.
The world’s first cryptocurrency is steadily becoming more popular and expensive every year. This motivates more individuals and companies to enter the mining business to earn a bitcoin share.

More miners, more efficient equipment

To validate a block of transactions and receive a reward, miners compete with each other by solving a deliberately complicated mathematical task, or puzzle. Those miners who own more computing power (hashrate) have more chances to win the competition. This incentivizes miners to buy more powerful equipment that consumes more electricity.
At the same time, mining equipment efficiency is constantly improving, and with time less electricity is required to produce the same hashrate. This factor allows to slow down the increasing demand for electricity.
For example, in 2016 Bitmain, world’s largest manufacturer of mining equipment, launched the legendary Antminer S9, which consumed 100 watts to produce one terahash per second, or 100 W/TH/s. The best modification of Antminer S15, released in 2018, consumed 57 W/TH/s. Currently, the most efficient Antminer S17 consumes only 40 W/TH/s.
https://preview.redd.it/gh343l3p09j41.png?width=930&format=png&auto=webp&s=e350c1e7832e37c1e3c3aeac974428cca7f0f874
It is assumed that the market competition compels manufacturers to keep up with each other in developing more efficient hardware. If some manufacturer brings next-generation chips to market, other manufacturers start to produce chips with the same characteristics at about the same time.
On the other hand, new miners are joining the network, thus increasing the hashrate. So the demand for electricity continues to grow. Also, it can be noticed later that the electricity consumption chart is similar to that of hashrate chart.
https://preview.redd.it/3k32ci6q09j41.png?width=930&format=png&auto=webp&s=e70f600419bcbc9e7e82506b5f12bf4da6f00584

Calculations

The incremental volume of electricity consumption is calculated by multiplying newly added hashrate by the best mining efficiency available at that moment.
The sum of incremental volumes represents cumulative amount of electricity consumed by bitcoin network. The metric is expressed in terawatt-hours (TWh). To get annualized volume in terawatt-hours we multiply the consumption by 24 hours and 365 days.
A 100-day moving average was applied to hashrate to make the final result less dependent on the short-term hashrate fluctuations.
Assumptions, used in this study, are very conservative. It means that the results are in the lower limit of the range of possible volumes, and the actual electricity consumption can be higher.
A detailed explanation and interactive charts are provided here: https://www.blockchainanalytics.pro/btc/electricity-consumption/

Results

Currently, annualized electricity consumption in bitcoin network is 57 TWh. To help readers get an idea of how much electricity the bitcoin network consumes, a comparison with some countries is provided alongside.
Portugal consumes 49 TWh per year, Romania – 50 TWh, Czech Republic – 59 TWh.
Some more numbers for comparison:

According to conservative estimates, the bitcoin network will consume more than 70 TWh in 2020. This is on a par with Chile, a country with 18 million population.

More thoughts (estimations of how much energy banking industry consumes)

Some information from official reports:
Taking into account the information above, we can assume that, on average, banks spend ~20 kWh per customer per year.
Some information on world population:
  • 69% of adults around the world have a banking account (source)
  • 70% of the world population are adults (source)
  • World population is 7.7 billion (source)
Finally: 7.7 billion people * 70% * 69% * 20 kWh per year = ~74 TWh per year
So, we can assume, that banking industry consumes ~74 TWh per year

Antminer T19 May Not Affect Bitcoin Hash Rate but Keeps Bitmain Ahead

The Antminer T19 by Bitmain may not have a big impact on the Bitcoin network, and it comes out amid the firm’s internal and post-halving uncertainty.
Earlier this week, Chinese mining-hardware juggernaut Bitmain unveiled its new product, an application-specific integrated circuit called Antminer T19. The Bitcoin (BTC) mining unit is the latest to join the new generation of ASICs — state-of-the-art devices designed to mitigate increased mining difficulty by maximizing the terahashes-per-second output.
The Antminer T19 announcement comes amid the post-halving uncertainty and follows the company’s recent problems with its S17 units. So, can this new machine help Bitmain to reinforce its somewhat hobbled position in the mining sector?
T19: The cheaper S19
According to the official announcement, the Antminer T19 features a mining speed of 84 TH/s and a power efficiency of 37.5 joules per TH. The chips used in the new device are the same as those equipped in the Antminer S19 and S19 Pro, though it uses the new APW12 version of the power supply system that allows the device to start up faster.
Bitmain usually markets its Antminer T devices as the most cost-effective ones, while the S-series models are presented as the top of the line in terms of productivity for their respective generation, Johnson Xu — the head of research and analytics at Tokensight — explained to Cointelegraph. According to data from F2Pool, one of the largest Bitcoin mining pools, Antminer T19s can generate $3.97 of profit each day, while Antminer S19s and Antminer S19 Pros can earn $4.86 and $6.24, respectively, based on an average electricity cost of $0.05 per kilowatt-hour.
Antminer T19s, which consume 3,150 watts, are being sold for $1,749 per unit. Antminer S19 machines, on the other hand, cost $1,785 and consume 3,250 watts. Antminer S19 Pro devices, the most efficient of three, are considerably more expensive and go for $2,407. The reason Bitmain is producing another model for the 19 series is due to what is known as "binning" chips, Marc Fresa — the founder of mining firmware company Asic.to — explained to Cointelegraph:
“When chips are designed they are meant to achieve specific performance levels. Chips that fail to hit their target numbers, such as not achieving the power standards or their thermal output, are often ‘Binned.’ Instead of throwing these chips in the garbage bin, these chips are resold into another unit with a lower performance level. In the case of Bitmain S19 chips that don’t make the cutoff are then sold in the T19 for cheaper since they do not perform as well as the counterpart.” The rollout of a new model “has nothing to do with the fact that machines are not selling well,” Fresa went on to argue, citing the post-halving uncertainty: “The biggest reason machines probably are not selling as well as manufacturers would like is because we are on a bit of a tipping point; The halving just happened, the price can go anyway and the difficulty is continuing to drop.” Product diversification is a common strategy for mining hardware producers, given that customers tend to aim for different specifications, Kristy-Leigh Minehan, a consultant and the former chief technology officer of Genesis Mining, told Cointelegraph:
“ASICs don’t really allow for one model as consumers expect a certain performance level from a machine, and unfortunately silicon is not a perfect process — many times you’ll get a batch that performs better or worse than projected due to the nature of the materials. Thus, you end up with 5–10 different model numbers.” It is not yet clear how efficient the 19-series devices are because they have not shipped at scale, as Leo Zhang, the founder of Anicca Research, summed up in a conversation with Cointelegraph. The first batch of S19 units reportedly shipped out around May 12, while the T19 shipments will start between June 21 and June 30. It is also worth noting that, at this time, Bitmain only sells up to two T19 miners per user “to prevent hoarding.”
Hardware problems and competitors
The latest generation of Bitmain ASICs follows the release of the S17 units, which have received mostly mixed-to-negative reviews in the community. In early May, Arseniy Grusha, the co-founder of crypto consulting and mining firm Wattum, created a Telegram group for consumers unsatisfied with the S17 units they purchased from Bitmain. As Grusha explained to Cointelegraph at the time, out of the 420 Antminer S17+ devices his company bought, roughly 30%, or around 130 machines, turned out to be bad units.
Similarly, Samson Mow, the chief strategy officer of blockchain infrastructure firm Blockstream, tweeted earlier in April that Bitmain customers have a 20%–30% failure rate with Antminer S17 and T17 units. “The Antminer 17 series is generally considered not great,” added Zhang. He additionally noted that Chinese hardware company and competitor Micro BT has been stepping on Bitmain’s toes lately with the release of its highly productive M30 series, which prompted Bitmain to step up its efforts:
“Whatsminer gained significant market share in the past two years. According to their COO, in 2019 MicroBT sold ~35% of the network hashrate. Needless to say Bitmain is under a lot of pressure both from competitors and internal politics. They have been working on the 19 series for a while. The specs and price look very attractive.” Minehan confirmed that MicroBT has been gaining traction on the market, but refrained from saying that Bitmain is losing market share as a result: “I think MicroBT is offering option and bringing in new participants, and giving farms a choice. Most farms will have both Bitmain and MicroBT side by side, rather than exclusively host one manufacturer.”
“I would say that MicroBT has taken up the existing market share that Canaan has left,” she added, referring to another China-based mining player that recently reported a net loss of $5.6 million in the first quarter of 2020 and cut the price of its mining hardware by up to 50%.
Indeed, some large-scale operations seem to be diversifying their equipment with MicroBT units. Earlier this week, United States mining firm Marathon Patent Group announced that it had installed 700 Whatsminer M30S+ ASICs produced by MicroBT. However, it is also reportedly waiting for a delivery of 1,160 Antminer S19 Pro units produced by Bitmain, meaning that it also remains loyal to the current market leader.
Will the hash rate be affected?
Bitcoin’s hash rate plummeted 30% soon after the halving occurred as much of the older generation equipment became unprofitable due to the increased mining difficulty. That spurred miners to reshuffle, upgrading their current rigs and selling older machines to places where electricity is cheaper — meaning that some of them had to temporarily unplug.
The situation has stabilized since, with the hash rate fluctuating around 100 TH/s for the past few days. Some experts attribute that to the start of the wet season in Sichuan, a southwest Chinese province where miners take advantage of low hydroelectricity prices between May and October.
The arrival of the new generation of ASICs is expected to drive the hash rate even higher, at least once upgraded units become widely available. So, will the newly revealed T19 model make any impact on the state of the network?
Experts agree that it won’t affect the hash rate to a major degree, as it’s a lower output model compared with the S19 series and MicroBT’s M30 series. Minehan said she doesn’t expect the T19 model “to have a huge impact that’s an immediate cause of concern,” as “most likely this is a run of <3500 units of a particular bin quality.” Similarly, Mark D’Aria, the CEO of crypto consulting firm Bitpro, told Cointelegraph:
“There isn’t a strong reason to expect the new model to significantly affect the hashrate. It might be a slightly more compelling option to a miner with extraordinarily inexpensive electricity, but otherwise they likely would have just purchased an S19 instead.” Bitmain continues to hold leadership despite internal struggle
At the end of the day, manufacturers are always in an arms race, and mining machines are simply commodity products, Zhang argued in a conversation with Cointelegraph:
“Besides price, performance, and failure rate, there are not many factors that can help a manufacturer differentiate from the others. The relentless competition led to where we are today.” According to Zhang, as the iteration rate naturally slows down in the future, there will be more facilities using “creative thermal design such as immersion cooling,” hoping to maximize the mining efficiency beyond just using most powerful machines.
As for now, Bitmain remains the leader of the mining race, despite having to deal with the largely defunct 17 series and an intensifying power struggle between its two co-founders, Jihan Wu and Micree Zhan, which recently resulted in reports of a street brawl.
“Due to its recent internal issues, Bitmain is facing challenges to keep its strong position in the future thus they started to look at other things to expand its industry influences,” Xu told Cointelegraph. He added that Bitmain “will still dominate the industry position in the near future due to its network effect,” although its current problems might allow competitors such as MicroBT to catch up.
Earlier this week, the power struggle inside Bitmain intensified even further as Micree Zhan, an ousted executive of the mining titan, reportedly led a group of private guards to overtake the company’s office in Beijing.
Meanwhile, Bitmain continues to expand its operations. Last week, the mining company revealed it was extending its “Ant Training Academy” certification program to North America, with the first courses set to launch in the fall. As such, Bitmain seems to be doubling down on the U.S.-based mining sector, which has been growing recently. The Beijing-based company already operates what it classifies as “the world’s largest” mining facility in Rockdale, Texas, which has a planned capacity of 50 megawatts that can later be expanded to 300 megawatts.

Test post

TH = 1012 = 10004 hashes_per_second EH = 1018 = 10006 hashes_per_second
21.113
0.101 daily USD per TH/s
116.73 EH/s
So I was discussing this last week and honestly it all felt too simple, so I'm trying to get some stronger counterpoints to this argument. Goes something like this.
You have some pool miner that wants to do a 51% attack. Lets assume the attack has three phases, the first phase is to try to accumulate 51% of the hashing power, next is the accumulation of more hashing power by ejecting other pools from through reorg. Finally when they aquired enough mining power they could blacklist exchange hotwallets or all manner of nefariousness. Lets further assume that everyone will act purely in their own self interest. For simplicity lets call the attacker "Spectre Pool".

Accumulation Phase

Assuming Spectre Pool can hit something like 41% of the hashing power, the first goal is to accumulate more resources to hit 51%. Since pool mining is a commodity market, all Spectre has to do in this imaginary world is offer more than the market rate. Since they are already at 41% hashrate, they need to entice another 10% of the market to come to their pool. The obvious way to do this would be to offer a "new customer bonus" or something like that. Some promotion where they pay 1% above market price for the hashing power of pool members. So, given a network hashrate of 116.73 EH and a market rate of 0.101 USD/TH per day, the cost they would have to bear to offer a 1% promotion to entice 10% of the network would be:
116.73_EH / 0.101_USD/TH * 10% * 1% = 1,155,742 USD per day for each 1% "bonus"
So, assuming they were willing to spend that much on "marketing", and that all miners worked in their own self interest, eventually they could lure enough miners over to achive 51%. Once they hit this threahold they could scale back on the "marketing" and thus reduce their daily burn.

Acceleration phase

Once at 51%, the next attack of Spectre will be to put their smallest competitor out of buisness. Lets call that the "Bond Pool", and pretend that Bond has 1.5% of the network hashing power. To put Bond out of buisness, with 51%, Spectere will need to reorg whenever Bond wins a block. By reorging to a chain without Bond, this will put Spectre one block behind and they will need to catch up. Once the reorg begins, Spectre will need to produce the longest chain on its own while starting one block behind. So we need to determine how long (statisticly) it will take Specter to produce an n+1 blocks and compare that to how long (statisticly) with take Bond to produce another block.
Although this can be hammered out iterive calculations, a better approach will be an algebraic solution. Lets walk through the equations:
You can put the following into a GeoGebra CAS calculator to substitute and simplify the equations
solve(n*m = s*(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(n*m = s*(n+1), d) n = s/(m-s) b = m*M/p solve(b = s*(n+1),p)
This will produce the following equations for the values we are interested in.
m(t,d): t*(1/2-d) # from `m` define s(t,d): t*(1/2-d) # from `s` define n(s,m): s/(m-s) # from `n` solve d(n): 1/(4*n+2) # from `d` solve p(d): 2*d # from `p` solve b(t,p): t/p # from `b` define
Here's a table
n d p m s b
25 0.98% 1.96% 20.40 19.62 510
20 1.22% 2.44% 20.50 19.52 410
15 1.61% 3.23% 20.67 19.38 310
10 2.38% 4.76% 21 19.09 210
5 4.55% 9.09% 22 18.33 110
4 5.56% 11.11% 22.50 18 90
3 7.14% 14.29% 23.33 17.50 70
2 10% 20% 25 16.67 50
1 16.67% 33.33% 30 15 30
solve(nm = s(n+1), d) n = s/(m-s) b = m*M/p
``` Tb = The avg time between blocks won by Bond durring the reorg Ts = The avg time for Spectre to produce a block durring the reorg Tm = The avg time for the main chain to produce a block durring the reorg n = The number of blocks Specter will need to reorg
Tb = 10_min / 49% / 3% = 10.89 Hrs Ts = 10_min / 51% = 19.61 Min Tm = 10_min / 49% = 20.41 Min
Solve for the amount of blocks Specter can reorg Tmn > Ts(n+1) Tnn > Tsn + Ts n > Ts/(Tn - Ts) n > 24.5
Therefore: Spectre can produce 26 blocks faster than the main chain can produce 25. Specter has to win the reorg before Bond produces another block
Assert: Ts * (n+1) < Tb 19.61_min * 26 < 10.89_hrs 8.50_hrs < 10.89_hrs ```
So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 10.89 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52%
Doing the same math again, with 52% Spectre can ice out any pool who has up to 7% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 16% of his competitors. This can cascade on and on until Spectre is the only public pool left.
1 - All "hashes" are hashes per second 2 - TH = 1012 or 10004 hashes per second 3 - EH = 1018 or 10006 hashes per second 4 - Assume a market rate of 0.101 USD / TH / day 5 - Assume an average daily network hashrate of 116.73 EH

Bitcoin Hashrate Records New All-Time High Amid Halving And BTC Bullish Momentum

Bitcoin Hashrate Records New All-Time High Amid Halving And BTC Bullish Momentum

With The Third Bitcoin Halving Already Here, Bitcoin Bulls Are Showing No Signs Of Support For The World’s Leading Cryptocurrency
While the crypto world was frantic about Bitcoin’s third halving event, which occurred on May 12, it came with a bullish sentiment among traders and holders. However, the halving produced 5%-8% price swings in both directions prior to the halving. The market didn’t seem to respond to the much-anticipated halving. The weekend saw $1,3 billion in liquidations, which put pressure on Bitcoin bulls. Shortly after Bitcoin’s reward cut, Bitcoin’s price peaked, before correcting itself to currently trading at $8,745.98
Meanwhile, the Bitcoin mining industry seems to be going all-in on validating blocks, as the computing power on Bitcoin’s network, or hashrate, increased to a new all-time high. The 140 terra hash-per-second (TH/s) all-time high surpassed the recent 135 TH/s all-time high of March 2020, meaning that miners deployed all their recourses to celebrate the halving event.
Source: Coinwarz
The crypto community welcomed the halving, as TIE published data, showing the word “halving” being present in over 2,900 tweets. Reddit also showed signs of buzzing in the moments prior to the halving and shortly after it. Joshua Frank, TIE’s founder commented on the data, stating that “Bitcoin became a hot topic in the past 30 days, with a 72-percent conversation surge, and with peaks in search terms of Bitcoin and halving crypto related terms in Twitter. Bitcoin also surpassed 50,000 daily tweets, which is a new six-month high.”

Source: Twitter
“In the 30-day window prior to the halving, the word “halving” appears to be dominant in the conversations, regarding Bitcoin,” Frank added.
Google searches for “bitcoin halving also increased four times, as opposed to the 2016 halving event.
However, most crypto enthusiasts believed Bitcoin would record double, or even triple-digit price increase, due to the halving. The short rally proved them wrong, but many consider the real price surge to start in the following 18 to 24 months. Historically, Bitcoin showed an initial decrease in value before skyrocketing in both price and trading volumes.
The halving event drove an increase in daily trading volumes in the month before the reward cut. However, trading volumes have increased 50 times since the last halving in 2016. Spot market volumes received a boost from a peak of $1,5 billion in June 2016, and it was close to $30 billion in April 2020.
Nevertheless, market players are still stagnant about making strong predictions about Bitcoin’s future price, as this time it would take longer for the market to gain from the bullish momentum the halving created.

Triple Increase On BTC Transaction Fees Just Before Bitcoin`s Third Halving

Triple Increase On BTC Transaction Fees Just Before Bitcoin`s Third Halving

The Average Price Per Bitcoin Transaction Reached $3,19 On 8th May, After Increasing With 300% From $0,62 Per BTC Transaction, As Of 26th April
The world of cryptocurrencies is franticly preparing for Bitcoin’s third halving event, which would cut down the reward that miners receive for validating transactions.
Historically, prior to a halving event, transaction fees skyrocket. The last halving resulted in peak transaction fee of $0,62, with transactions costing a mere $0,10 just weeks before.
Source: Bitinfocharts
However, the halving event means something more than just transaction fees increase. Bitcoin suffered from increased volatility over the past weekend, with prices swinging from close to $9,700 on May 10, to shrink as low as $8,466 on May 11. Nevertheless, Bitcoin’s price is still 40% up year-to-date (YTD), which implies strong support from Bitcoin bulls. The price swing outperforms serious investment assets like gold (XAU) and U.S. dollars.
Speculators expect the halving event to boost Bitcoin’s price, as the price inflation reduces when the reward for mining a Bitcoin block reduces in half. Тhe primary reason behind both Bitcoin’s price increase and inflation reduction is a term, called scarcity. Scarcity resembles how rare to obtain a given asset is. Meantime, Bitcoin’s user base is exponentially increasing. The current 1,800 BTC-per-day premium would be reduced to 900 BTC per day.
Joe Llisteri, the co-founder of crypto derivatives exchange Interdax, stated that over time, the reduction of BTC supply would ultimately lead to a reduction in sell pressure. “The factors add up to an increase in upwards momentum for Bitcoin’s price.”, Llisteri added.
Llisteri also noted that this time Bitcoin’s upwards momentum may see a slower effect, due to progressively longer life cycles for Bitcoin after a halving event. “Currently, we are looking at 18-24 months until a possible all-time high. Timewise, Bitcoin may reach an all-time high between October-November 2021 and May-June 2022.”, Llisteri concluded.
However, small and medium-sized miners may take a serious hit, as the price reward cut may mitigate all possible earnings from small mining enthusiasts and mid-sized mining rigs. Even with the much-anticipated Bitcoin price boost, much of the miners may shut down operations prior to the price increase.
Speaking of mining, Bitcoin’s hash rate continues to keep a steady growth, slightly declining from its yearly high of 123.2 terra hash-per-second (TH/s). There are two possible scenarios – either more miners are joining the Bitcoin network, or current miners are driving their existing rigs to a maximum.

Bitcoin hashrate hits a new ATH again

The aggregate computing power of the Bitcoin network exceeded the historical maximum, reaching 68,631,992 TH/s.
https://www.blockchain.com/charts/hash-rate?timespan=2years
Another interesting fact is the number of active addresses per day. The first time BTC exceeded 1 million active addresses in 24 hours was November 2017 when 1 BTC was worth $9352 and the average fee was $3.23.
It happened again on Friday: over 1 million addresses were active and the fees paid by users were on average $1.33. These numbers hadn’t been seen for a long time.
Among the technical reasons that are favouring the growth of the value of Bitcoin, there is also the approaching of the so-called “Halving” (the process of reducing the reward for finding a new block; more detailed here: https://medium.com/letknownews/what-is-halving-and-how-does-it-affect-the-bitcoin-rate-c48a994c833a). The first halving took place in 2012: the reward for a block had decreased from 50 BTC to 25 BTC. The second, on the other hand, occurred in 2016 and went from 25 to 12.5 BTC per block. In both cases, as a direct effect of the reduction in supply, there was an increase in the value of the cryptocurrency.
The next halving is now imminent. In 11 months’ time, in fact, the reward for miners will be halved from 12.5 BTC per block to 6.25 BTC per block. The inflation rate will fall below 2%. The following halving will, therefore, occur in 2024 and 1 block reward will correspond to 3,125 BTC, the rate of inflation will fall below 1%, perhaps even below 0.5%.

Bitcoin Mining Unit Manufacturer MicroBT Nibbles at Bitmain’s Market Share

Bitcoin Mining Unit Manufacturer MicroBT Nibbles at Bitmain’s Market Share


Bitcoin miner maker MicroBT has rapidly expanded market share by selling over half a million units in 2019, chipping away at rival Bitmain's dominance.
MicroBT sold about 600,000 units of its flagship WhatsMiner M20 series last year, Vincent Zhang, sales head of the Shenzhen-based company, said in an online panel hosted by Chinese mining pool Poolin on Thursday in a WeChat group.
These products generate a computing power of about 60 terahashes per second (TH/s) on average, he said. That means the newly delivered 600,000 units may have contributed over 30 exahashes (EH/s) of hashing power to the bitcoin network in 2019. (1 EH = 1 million TH).
Amid bitcoin's price jump throughout 2019, the network's two-week average computing power more than doubled from just 40 EH/s around the end of 2018 to nearly 100 EH/s in December. That'd mean close to half of bitcoin's computing power growth in 2019 may have come from equipment delivered by MicroBT.
Zhang didn't specify the precise average unit price of these batches, as they could fluctuate depending on bitcoin's price over the year. But the firm's various models in its M20 product line are generally priced between $24 to $30 per terahash, meaning the firm has brought home a high nine-figure revenue in U.S. dollars for 2019.
Bitcoin's current computing power stands at 110 EH/s. That also means MicroBT may account for around 30 percent of bitcoin mining power sold right now, making it one of the largest and fastest-growing miner makers in the world.

We have been stress testing the BCH infrastructure to prove Bitcoin Cash's ability to scale, it has held up exceptionally well!

This account is a throwaway for obvious reasons. We are a small group part of a larger stress test team.
Over the past 24 hours there has been a huge increase in the number of transactions, most of these have been produced by ourselves and other teams. The reason why we are doing this is to prove the capability of the Bitcoin Cash network in terms of number of transactions as well as transaction fees, In our opinion it has held up exceptionally well.
We have chosen to Stress test because it is a critical time for Bitcoin cash, Huge increases in adoption from merchants and payment services (BitPay) as well as BTC/BCH pairs opening on GDAX/CoinBase on the 17th. With Bitcoin Cash being the cheapest to move in and out of CoinBase/Gdax, we expect an uptick in transactions from people moving away from the high fees on Bitcoin Core.
Thousands of 1sat/byte transactions are being broadcast to the network (High outputs), meaning the size of the mempool increasing. This simulates heavy network usage as well as spam attacks. This level of usage rivals Litecoin as well as Bitcoin core.
This will have very low impact on regular users since most wallets use 2+ sat/byte. Regular transactions will always be processed in the next block.
The current average tx/block are floating around 800-1,200, this is about 150,000 tx/day. Yet fees has remained ~$0.02
This test costs thousands of dollars to sustain even at 1sat/byte, further improvements to the Bitcoin Cash infrastructure (32mb blocks/Graphene) will greatly decrease the ability of users to maliciously spam the network.
To really visualise this we recommend txhighway.com

Why is it so hard to mine for bitcoin?

Why is it so hard to mine for bitcoin?
Bitcoin mining has become more competitive than ever.
Bitcoin mining difficulty – the measure of how hard it is to earn mining rewards in the world’s largest cryptocurrency by market cap – has reached a new record high above 7.93 trillion. That’s a seven percent jump from the 7.45 trillion record set during the recent two-week adjustment cycle, which was the highest since October 2018.
Bitcoin is designed to adjust its mining difficulty every 2,016 blocks (approximately 14 days), based on the amount of computing power deployed to the network. This is done to ensure the block production interval at the next period will remain constant at around every 10 minutes. When there are fewer machines racing to solve math problems to earn the next payout of newly created bitcoin, difficulty falls; when there are more computers in the game, it rises.

Data from Bitcoin Block Explorer - BTCNEWZ.com
Right now the machines are humming furiously. Bitcoin miners across the world have been performing calculations at an average 56.77 quintillion hashes per second (EH/s) over the last 14 days to compete for mining rewards on the world’s first blockchain, according to data from mining pool.
Data further indicates the average bitcoin mining hash rate in the last 24-hour and three-day periods were 59.58 EH/s and 59.70 EH/s, respectively, even higher than the average 56.77 EH/s from May 15 to June 27, or any 14-day data in the network’s history.
Similarly, data from blockchain also shows the aggregate of bitcoin computing power was around 66 EH/s as of June 22, surpassing last year’s record high of 61.86 EH/s tracked by the site, and has more than doubled since December 2018 when the hash rate dropped to as low as 31 EH/s amid bitcoin’s price fall.
Assuming all such additional computing power has come from more widely used equipment such as the AntMiner S9, which performs calculations at an average rate of 14 tera hashes per second (TH/s), that suggests more than 2 million units of mining equipment may have been switched on over the past several months. (1 EH/s equals to 1 million TH/s)

The increase in capacity is also in line with bitcoin’s price jump over the first half of 2019, which caused the price of second-hand mining equipment to double in China, and also juiced demand for new machines.
Further estimates the bitcoin mining difficulty will jump by another seven percent at the beginning of the next adjustment cycle, which would be the first time for bitcoin mining difficulty to cross the eight trillion threshold.
Delayed plugging in
Such computing interest comes at a time when mining farms in China, especially in the country’s mountainous southwest, have been gradually plugging in equipment as the rainy summer approaches.
According to a report published by blockchain research firm Coinshare, as of earlier this month, 50 percent of the global bitcoin computing power was located in China’s Sichuan province.
However, it’s important to note that this year, the arrival of the rainy season in China’s southwest has been delayed by nearly a month compared to previous years. As a result, some local mining farms were only running less than half of their total capacity in the past month.
Xun Zheng, CEO of mining farm operator Hashage based in Chengdu that owns several facilities across China’s southwestern provinces, said there had been no rain in the area for over 20 days since early May, which was “unusual.”
“In the past years, it usually starts raining continuously throughout May so [hydropower plants] normally will have enough water resources by early June,” he said.
As a result, in early June his firm was only operating at 40 percent of capacity; it can host more than 200,000 ASIC miners. But as the rain has arrived gradually over the past two weeks, the proportion has climbed to over 60 percent.
Mining farms in China previously estimated that the total hash rate this year during the peak of the rainy season around August could break the threshold of 70EH/s. That means another 300,000 units of mining machines could be further activated, assuming all are AntMiner S9s or similar models.
Those waiting to be switched on will also include new capital in the sector such as Shanghai-based Fundamental Labs, a blockchain fund that has invested $44 million on top-of-the-line mining equipment, which will be activated in June.

Bitcoin hashrate hits a new ATH again

The aggregate computing power of the Bitcoin network exceeded the historical maximum, reaching 68,631,992 TH/s.
https://www.blockchain.com/charts/hash-rate?timespan=2years
Another interesting fact is the number of active addresses per day. The first time BTC exceeded 1 million active addresses in 24 hours was November 2017 when 1 BTC was worth $9352 and the average fee was $3.23.
It happened again on Friday: over 1 million addresses were active and the fees paid by users were on average $1.33. These numbers hadn’t been seen for a long time.
Among the technical reasons that are favouring the growth of the value of Bitcoin, there is also the approaching of the so-called “Halving” (the process of reducing the reward for finding a new block; more detailed here: https://medium.com/letknownews/what-is-halving-and-how-does-it-affect-the-bitcoin-rate-c48a994c833a). The first halving took place in 2012: the reward for a block had decreased from 50 BTC to 25 BTC. The second, on the other hand, occurred in 2016 and went from 25 to 12.5 BTC per block. In both cases, as a direct effect of the reduction in supply, there was an increase in the value of the cryptocurrency.
The next halving is now imminent. In 11 months’ time, in fact, the reward for miners will be halved from 12.5 BTC per block to 6.25 BTC per block. The inflation rate will fall below 2%. The following halving will, therefore, occur in 2024 and 1 block reward will correspond to 3,125 BTC, the rate of inflation will fall below 1%, perhaps even below 0.5%.

Decred Journal – July 2018

Note: you can read this on Medium, GitHub or old Reddit to view all the links

Development

dcrd: Several steps towards multipeer downloads completed: an optimization to use in-memory block index and a new 1337 chain view. Maintenance: improved test coverage, upgrading dependency management system and preparing for the upcoming Go 1.11 release.
dcrwallet: A big change introducing optional privacy-preserving SPV sync mode was merged. In this mode dcrwallet does not download the full blockchain but only gets the "filters", uses them to determine which blocks it needs and fetches them from random nodes on the network. This has on-disk footprint of 300-400 MB and sync time of minutes, compared to ~3.4 GB and sync time of hours for full sync (these are rough estimates).
jy-p: the server side of SPV (in dcrd) was deployed in v1.2.0, the client side of SPV (in dcrwallet) is in our next release, v1.3.0. Still some minor bugs in SPV that are being worked out. There will be an update to add the latest features from BIP 157/158 in the next few months. SPV will be optional in v1.3.0, but it will become the default after we get a proper header commitment for it (#general)
Decrediton: besides regular bugfixes and design improvements, several components are being developed in parallel like SPV mode, Politeia integration and Trezor support.
Politeia: testing started on mainnet, thanks to everyone who is participating. A lot of testing, bugfixing and polishing is happening in preparation for full mainnet launch. There are also a few missing features to be added before launch, e.g. capacity to edit a proposal and versioning for that, discussion to remain open once voting starts. Decrediton integration is moving forward, check out this video for a demo and this meta issue for the full checklist.
Trezor: Decrediton integration of initial Trezor support is in progress and there is a demo.
Android: app design version 2.0 completed.
dcrdata: development of several chart visualizations was completed and is awaiting deployment. Specifically, voting agendas and historic charts are merged while ticket pool visualization is in testing.
atomicswap: @glendc is seeking reviews of his Ethereum support pull request.
Dev activity stats for July: 252 active PRs, 220 master commits, 34,754 added and 12,847 deleted lines spread across 6 repositories. Contributions came from 6-10 developers per repository. (chart)

Network

Hashrate: the month started at 40.5 and ended at 51.6 PH/s, with a low of 33.3 and a new all time high of 68.4 PH/s. F2Pool is leading with 40-45%, followed by the new BeePool at 15-25% and coinmine.pl at 18-23%.
Staking: 30-day average ticket price is 92.6 DCR (-2.1). The price started the month at 94.6 and quickly retreated to month's low of 85 until 1,860 tickets were bought within a single period (versus target 720). This pushed the pool of tickets to 41,970 (2.5% above target), which in turn caused 10 price increases in a row to the month's high of 100.4. This was the highest ticket price seen on the new ticket price algorithm which has been in effect since Jul 2017. Second half of the month there was unusually low volatility between 92 and 94 DCR per ticket. Locked DCR held between 3.75 and 3.87 million or 46.6-48.0% of supply (+0.1% from previous peak).
Nodes: there are 212 public listening and 216 normal nodes per dcred.eu. Version distribution: 67% on v1.2.0 (+10%), 24% on v1.1.2 (-1%), 7% on v1.1.0 (-7%). Node count data is not perfect but we can see the steady trend of upgrading to v1.2.0. This version of dcrd is notable for serving compact filters. The increased count of such full nodes allows the developers to test SPV client mode in preparations for the upcoming v1.3.0 release.

ASICs

Obelisk posted three updates in July. For the most recent daily updates join their Discord.
New miner from iBeLink: DSM7T hashes Blake256 at 7 TH/s or Blake2b at 3.5 TH/s, consumes 2,100 W and costs $3,800, shipping Aug 5-10.
There were also speculations about the mysterious Pangolin Whatsminer DCR with the speed of 44 TH/s at 2,200 W and the cost of $3,888, shipping November. If you know more about it please share with us in #pow-mining channel.

Integrations

Meet new stake pool: dcrpool.ibitlin.com has 1% fees and is hosted by @life.
An interesting detail about decredbrasil.com stake pool was posted in chat:
emiliomann: stakebrasil is one of the pools with the lowest number of missed and expired tickets. It was one of the first and has a smaller percentage than the most recent ones who haven’t had the time to do so. (...) The Brazilian pool should be the one with the more servers spread around the world: 6 to decrease the latency. This is to explain to you why the [pool fee] rate of 5% (currently around 0.06 DCR) on the reward is also one of the highest. girino: 8 voting wallets now. I just finished setting up a new one yesterday. All of them in different datacenters, 3 in europe, 3 in north america, 1 in brazil and one in asia. We also have 3 more servers, 1 for the front end, one for "stats" and one for dcrdata. (#general)
On the mining side, Luxor started a new set of pool servers inside mainland China, while zpool has enabled Decred mining.
StatX announced Decred integration into their live dashboard and public chat.
Decred was added to Satowallet with BTC and ETH trading pairs. Caution: do your best to understand the security model before using any wallet software.

Adoption

VotoLegal update:
Marina Silva is the first presidential candidate in Brazil using blockchain to keep all their electoral donations transparent and traceable. VotoLegal uses Decred technology, awesome use case! (reddit)
The story was covered by criptonoticias.com (translated) and livecoins.com.br (translated), the latter received hundreds of upvotes and comments on brasil.
On the OTC trading front, @i2Rav from i2trading reports:
We continue to see institutional interest in DCR. Large block buyers love the concept of staking as a way to earn additional income and appreciate the stakeholder rights it affords them. Likening a DCR investment to an activist shareholdebondholder gives these institutions some comfort while dipping their toes into a burgeoning new asset class.

Marketing

Targeted advertising reports released for June and July. As usual, reach @timhebel for full versions.
Big news in June: Facebook reversed their policy on banning crypto ads. ICO ads are still banned, but we should be OK. My team filled out the appeal today, so we should hopefully hear something within a few days. (u/timhebel on reddit)
After couple weeks Facebook finally responded to the appeal and the next step is to verify the domain name via DNS.
A pack of Stakey Telegram stickers is now available. Have fun!

Peter Todd's RBF (Replace-By-Fee) goes against one of the foundational principles of Bitcoin: IRREVOCABLE CASH TRANSACTIONS. RBF is the most radical, controversial change ever proposed to Bitcoin - and it is being forced on the community with no consensus, no debate and no testing. Why?

Many people are starting to raise serious questions and issues regarding Peter Todd's "Opt-In Full RBF", as summarized below:
(1) RBF violates one of the fundamental principles of the Bitcoin protocol: irrevocable cash transactions.
Interesting point!
Th[is] really is [a] drastically different vision of what Bitcoin according to the core dev team...
It would be nice [if] they [wrote their] own "white paper" so we know where they are going...

"From a usability / communications perspective, RBF is all wrong. When the main function of your technology is to PREVENT DOUBLE SPENDING, you don't add an "opt-in" feature which ENCOURAGES DOUBLE SPENDING."

(2) Who even requested RBF in the first place? What urgent existing "problem" is RBF intended to solve? If you claim to be a supporter of RBF, would you be willing to go on the record and comment here on how it would personally benefit you?
Still waiting for an answer to the fundamental question: where is the demand for this "feature" coming from?

Intentionally doing zero-conf for any reason other than expediting a payment to the same recipients is nothing more than attempted fraud. There needs to be a good reason for enabling this, and last time I looked the case has not been made.
People with a black and white view of the world who believe "0 conf bad, 1 conf good" simply do not understand how bitcoin works. By its random nature, bitcoin never makes final commitment to a transaction. Even with six confirmations there is still a chance the transaction will be reversed. In other words, bitcoin finality is not black and white. Instead, there is a probability distribution of confidence that a transaction will not be reversed. Software changes that make it easier to defraud people who have been reasonably accepting 0 conf transactions are of highly questionable value, as they reduce the performance (by increasing delay for a given confidence).
If transactions with appropriate fees start failing to ever confirm because of "block size" issues, then bitcoin is simply broken and, if it can not be fixed bitcoin will end up as dead as a doornail.

Transactions spending the same utxo were (until now) not relayed (except by XT nodes). So it wasn't as simple as just sending a double spend, because the transaction wouldn't propagate. FSS-RBF seemed like a good option to get your tx unstuck if you paid too little. Pure RBF I'm not sure what the point of it is. What problem is it solving?

When F2Pool implemented RBF at the behest of Peter Todd they were forced to retract the changes within 24 hours due to the outrage in the community over the proposed changes.
So the opposite is actually true. The community actively do not want this change. Has there been any discussion whatsoever about this major change to the protocol?

(3) RBF breaks zero-conf. Satoshi supported zero-conf. Were any actual merchants who have figured out pragmatic business approaches using zero-conf even consulted on this radical, controversial change?
My business accepts bitcoin and helps people with minor cash transfers and purchases. Fraud has NEVER been an issue as long as the transactions have been broadcast on the blockchain with appropriate fees. We usually send people their cash as soon as the transaction is broadcast.
Now we have to wait 10 minutes to avoid getting cheated out of hundreds of dollars, vastly increasing the service cost of accepting bitcoin. And we have to tell customers we promote bitcoin to that they are likely to be cheated if they don't wait 10 minutes while buying their bitcoin. It is such a spectacularly stupid thing to do, adding uncertainty and greater potential for fraud at every link of the transaction chain. Thanks a lot, Peter.

Jeez, we need to give this "zero-conf was never safe" meme a rest already. Cash was also "never safe", but it's widely used because it works reasonably well in the context it's used. These people would probably advocate for a cashless society as well.

I believe it'll be possible for a payment processing company to provide as a service the rapid distribution of transactions with good-enough checking in something like 10 seconds or less.
The network nodes only accept the first version of a transaction they receive to incorporate into the block they're trying to generate. When you broadcast a transaction, if someone else broadcasts a double-spend at the same time, it's a race to propagate to the most nodes first. If one has a slight head start, it'll geometrically spread through the network faster and get most of the nodes.
A rough back-of-the-envelope example:
1 0
4 1
16 4
64 16
80% 20%
So if a double-spend has to wait even a second, it has a huge disadvantage.
The payment processor has connections with many nodes. When it gets a transaction, it blasts it out, and at the same time monitors the network for double-spends. If it receives a double-spend on any of its many listening nodes, then it alerts that the transaction is bad. A double-spent transaction wouldn't get very far without one of the listeners hearing it. The double-spender would have to wait until the listening phase is over, but by then, the payment processor's broadcast has reached most nodes, or is so far ahead in propagating that the double-spender has no hope of grabbing a significant percentage of the remaining nodes.

Zero conf was always dangerous, true, but the attacker is rolling a dice with a double spend. And it is detectable because you have to put your double spend transaction on the network within the transaction propagation time (which is measured in seconds). That means in the shop, while the attacker is buying the newspaper, the merchant can get an alert from their payment processor saying "this transaction has a double spend attempt". Wrestling them to the ground is an option. Stealing has to be done in person... No different then from just shop lifting. The attacker takes their chance that the stealing transaction won't be the one that is mined.
With rbf, the attacker has up to the next block time to decide to release their double spend transaction. That means the attacker can be out of the shop and ten minutes away by car before the merchant gets the double spend warning from their payment processor. Stealing is not in person and success is guaranteed by the network.
Conclusion: every merchant and every payment processor will simply refuse to accept any rbf opt in transaction. That opt in might as well be a flag that says "enable stealing from you with this transaction"... Erm no thanks.
There might be a small window while wallet software is updated, but after that this " feature " will go dark. Nobody is going to accept a cheque signed "mickey mouse", and nobody is going to accept a transaction marked rbf.
Strangely, that means all this fuss about it getting merged is moot. It will inevitably not be used.

(4) What new problems could RBF create?
This opens up a new kind of vandalism that will ensure that no wallets use this feature.
The way it works is that if you make a transaction, and then double spend the transaction with a higher fee, the one with the higher fee will take priority.

(5) RBF apologists such as eragmus have been trying to placate objections by repeatedly emphasizing that this version of RBF is ok, saying that this is only "Opt-In (Full) RBF". But does the "opt-in" nature of this particular implementation of RBF really mitigate its potential problems?
"opt-in" is a bit of a red-herring.
As I understand: say I'm a vendor who doesn't want to accept RBF transactions. So I don't opt-in. I'm still stuck accepting RBF transactions because the sender, not the receiver, has the control.

It's opt-in in theory, but that means everyone in the community who writes software which deals with transactions now has to develop code to deal with the ramifications.

Yes it is opt-in, which means I have to anticipate ... congestion beforehand to use it. This has caused me troubles recently. Normally I use low-fee mode to transact and switch mode when the network is congested. A few times either I did not know about the congestion or forgot to switch mode and my txn got stuck for 12-48h. So for me this opt-in does nothing of help. If I was conscious about the congestion I would have switch to high-fee mode, no RBF needed.
...Or I have to enabled RBF for all my txns. Then there's problem of receivers have to all upgrade their wallet after the wallet devs choose to implement it. And just to add one more major complication when consider 0-conf.

"Hopefully this will give Bitcoin payment processors a financial incentive to support Lightning Network development."
https://www.reddit.com/bitcoinxt/comments/3ujq69/uriplin_on_rbitcoin_inadvertently_reveals_the/
It seems to me like RBF is addressing a problem (delays due to too-low fees) which would not exist if we had larger blocks. It seems fishy to make this and lightning networks to solve the problem when there's a much simpler solution in plain view.
We should set the bar for deceit and mischief unusually high on this one bc there is so much at stake, an entire banking empire.

This maybe a needed feature if Bitcoin get stuck with 1MB..
You might need to jack-up the fee several time to get your fees in a blocks in the future..
It seems that 1MB crrippecoin is really part of their vision.

RBF makes sense in a world where blocks are small and always full.
It creates a volatile transaction pricing market where bidders try to outbid each other for the limited space in the current block of txns.
It serves the dual goals of limiting transactions and maximizing miner revenue resulting from the artificial scarcity being imposed by the block size limit.
The unfortunate side effect is that day to day P2P transactions on the Bitcoin network will become relatively expensive and will be forced onto another layer, or coin.

RBF offers nothing in a world where there is always a little extra space in the block for the next transaction. It only makes sense in a world where blocks are full.

(7) RBF violates two common-sense principles:
- "KISS" (Keep It Simple Stupid);
- "If it ain't broke, don't fix it"
To say it a bit harsher but IMO warranted: P. Todd seems to be busy inventing useless crap and making things complicated for wallet devs...

(8) Why is the less-safe version of RBF the one being released ("Full") rather than the "safe(r)" version (FSS - First-Seen Safe)?
Peter Todd had proposed two different versions of RBF: "Full" vs "FSS" (First-Seen Safe).
"Full" is the more dangerous version, because it allows general double-spending (I can't even believe we're even saying things like "allows general double-spending" - but that's the kind of crap Peter Todd is trying to foist on us).
"FSS" is supposedly a bit "safer", because is only allows double-spending a transaction with the same output.
What's being released now is "Opt-In Full RBF".
First-seen-safe restricts replace-by-fee to only replacing transactions with the same output (prevents double spending).
The reason this feature is being added is they see Bitcoin as a settlement network, so when there's a backlog users should be able to replace their transaction with a higher-fee one so it's included. It's to deal with the cripplingly low blocksizes.
Someone should just implement and merge first-seen-safe, since that's much more non-controversial. Keeps 0-confs safe(r) while enabling re-submitting transactions.

I would have preferred first-seen-safe RBF, certainly. It can be a useful tool to just bump the transaction fee on an existing transaction.
coinaday
https://www.reddit.com/bitcoinxt/comments/3uii16/on_black_friday_with_9000_transactions_backlogged/cxf5eno
Ok, so if the only benefit of RBF is to unstick stuck transactions by increasing the fee; why did you use "Full RBF" instead of "FSS RBF"? Full RBF allows the sender to increase the fee and change who the receiver is. FSS (First-Seen-Safe) RBF only allows the sender to increase the fee, but does not allow the sender to change who the receiver is.
Tldr: FSS RBF should be enough to enable your wanted benefit of being able to resend stuck transactions by increasing their fee, but you chose Full RBF anyway. Why?
todu
https://www.reddit.com/btc/comments/3uighb/on_black_friday_with_9000_transactions_backlogged/cxfm5qb
The benefit of opt-in RBF:
Now, when a transaction is not going through because fee was accidentally made too low or if there is a spam attack on the network, a user can "un-stuck" his/her transaction by re-sending it with a higher fee. No more being held to the mercy of miners maybe confirming your transaction, or not. The user gets some power back.
If this was the actual problem at hand, why not restrict the RBF to only increasing the fee, but not changing the output addresses.
RBF in it's current form is nothing but a tool to facilitate double spending. That is, it lowers the bar for default nodes to assist facilitating double spending. Which is VERY BAD for Bitcoin, imho.
Serisouly, I don't know what's gotten into those devs ACK'ing this decrease in Bitcoin's trustwortiness.

(9) Peter Todd has a track record of trying to break features which aren't perfect - even when real-world users find those features "good enough" to use in practice. Do you support Peter Todd's perfectionist and vandalist approach over the pragmatist "good-enough" approach, and if so, why or why not?
Destroying something just because it isn't perfect is stupid. By that logic we should even kill Bitcoin itself.

(10) Could the "game theory" on RBF backfire, and end up damaging Bitcoin?
And what if some/all miners simply hold RBF-enabled transactions into a separate pool and extract maximum value per transaction i.e. wait until senders cough up more & more ...
A very dangerous change that will actively encourage miners to collaborate on extracting higher fees or even extorting senders trying to 'fix' their transactions.

https://www.reddit.com/bitcoinxt/comments/3uii16/on_black_friday_with_9000_transactions_backlogged/cxfkozk
Peter Todd has a history of loving Game Theory, but he hasn't really applied those principals to the technological changes he's unilaterally making.
I don't understand how so many people could have been driven away or access removed so now he's able to make these changes despite community outcry.
DeftNerd
https://www.reddit.com/bitcoinxt/comments/3uii16/on_black_friday_with_9000_transactions_backlogged/cxfkyok
A miner could simply separate all RBF-enabled TX into a separate list and wait for higher and higher fees to be paid. It's kind of like putting a "Take my money, Pls!!!" sign on your forehead and and going shopping.

(11) RBF is a controversial, radical change to the Bitcoin protocol. Why has Peter Todd been allowed to force this on our community with no debate, no consensus and no testing?
It's not uncontroversial. There is clearly controversy. You can say the concerns are trumped up, invalid. But if the argument against even discussing XT is that the issue is controversial, the easy ACK'ing of this major change strikes many as hypocritical.
There is not zero impact. Someone WILL be double spent as a result of this. You may blame that person for accepting a transaction they shouldn't, or using a wallet that neglected to update to notify them that their transaction was reversible. But it cannot be said that no damage will result due to this change.
And in my view most importantly, RBF is a cornerstone in supporting those who believe that we need to keep small blocks. The purpose for this is to enable a more dynamic fee market to develop. I fear this is a step in the direction of a slippery slope.
(12) How does the new RBF feature activate?
Does anyone know how RBF activates? I mean if wallets are not upgraded this could be very dangerous for users. Because even if its opt-in this could kill zero confirmation for good.

https://medium.com/@octskyward/replace-by-fee-43edd9a1dd6d
(15) If you're against RBF, what can you do?
the solution to all this, is actually rather simple. Take the power away from these people. Due to the nature of bitcoin, we've always had that power. There never was a need for an "official" or "reference" implementation of the software. For a few years it was simply the most convenient, the mo[s]t efficient, and the best way to work out all the initial kinks bitcoin had. It was also a sort of restricted field in that (obviously) there were few people in the world who truly understood to the degree required to make a) design change proposals, and b) code for them (and note that while up until now this has been the case, it's not necessary for these 2 roles to be carried out by the same people). The last few months' debates over the blocksize limit have shown and educated thst a lot of people now truly understand what's what. And what's more one of the original core-devs (Gavin), already gave us the gift of proving in the real world that democracy in bitcoin can truly exist via voting with the software one (or miners) runs, without meaning to.
BitcoinXT was a huge gift to the community, and it's likely to reach its objective in a few months. It seems an implementation of bitcoin UL will test the same principle far sooner than we thought.
So the potential for real democracy exists within the network. And we're already fast on our way to most of the community stop[p]ing using core as the reference client. Shit like what Peter pulled yesterday, I predict, will simply accelerate the process. So the solution is arriving, and it's a far better solution th[a]t it would be to, say, locking Peter out of the project. Thi[s] will be real democracy.
I also predict in a couple of years a lot of big mining groups/companies/whatever will have their own development teams making their internal software available for everyone else to use. This will create an at[]mosphere of true debate of real issues and how to solve them, and it will allow people (miners) to vote with their implementations on what the "real" bitcoin should be and how it should function.
Exciting times ahead, the wheels are already in motion for this future to come true. The situation is grave, I won't deny that, but I do believe it's very, very temporary.

Decred Journal – August 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link) to see all the links.

Development

dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub.
The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.
Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.
The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.
The testnet was reset and bumped to version 3.
Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.
@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.
dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.
Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.
Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.
@degeri joined to perform security testing of Politeia and found several issues.
dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.
The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org.
Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.
iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.
Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.
docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.
@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals.
decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here).
decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.
Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)

Network

Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%.
Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.
Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.

ASICs

Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.
Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.
FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.
Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations

www.d1pool.com joined the list of stakepools for a total of 16.
Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.
Three new OTC desks were added to exchanges page at decred.org.
Two mobile wallets integrated Decred:
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?

Adoption

Merchants:

Marketing

Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here.
Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

Community Discussions

Community stats:
Comm systems news:
After another debate about chat systems more people began testing and using Matrix, leading to some gardening on that platform:
Highlights:
Reddit: substantive discussion about Decred cons; ecosystem fund; a thread about voter engagement, Politeia UX and trolling; idea of a social media system for Decred by @michae2xl; how profitable is the Obelisk DCR1.
Chats: cross-chain trading via LN; plans for contractor management system, lower-level decision making and contractor privacy vs transparency for stakeholders; measuring dev activity; what if the network stalls, multiple implementations of Decred for more resilience, long term vision behind those extensive tests and accurate comments in the codebase; ideas for process for policy documents, hosting them in Pi and approving with ticket voting; about SPV wallet disk size, how compact filters work; odds of a wallet fetching a wrong block in SPV; new module system in Go; security of allowing Android app backups; why PoW algo change proposal must be specified in great detail; thoughts about NIPoPoWs and SPV; prerequisites for shipping SPV by default (continued); Decred vs Dash treasury and marketing expenses, spending other people's money; why Decred should not invade a country, DAO and nation states, entangling with nation state is poor resource allocation; how winning tickets are determined and attack vectors; Politeia proposal moderation, contractor clearance, the scale of proposals and decision delegation, initial Politeia vote to approve Politeia itself; chat systems, Matrix/Slack/Discord/RocketChat/Keybase (continued); overview of Korean exchanges; no breaking changes in vgo; why project fund burn rate must keep low; asymptotic behavior of Decred and other ccs, tail emission; count of full nodes and incentives to run them; Politeia proposal translations and multilingual environment.
An unusual event was the chat about double negatives and other oddities in languages in #trading.

Markets

DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.
@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.
The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.
Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)
Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).
Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.
Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.
Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.
Finally, unrelated to Decred but good for a laugh: yetanotherico.com.
