IamA High School drop out that had a million dollar bet with his parents that if I made a million before I'm 18. I did not have to go to college! I won! AMA!
Hello Reddit! You may have seen me at the top of /technology the other day and I got a lot of messages telling me to do an IAMA about this article on CNBC so here I am! So I made a bet with my parents that if I turned 18 and was a millionaire, my parents wouldn't force me to go to college. I’m proud to say I won that bet! Thanks to some clever investments, making money from projects, and as is the case with everyone who has any kind of success (or even failure) a little bit of luck. Here’s the story of how it happened: When I was 12 years old in May 2011, my older brother showed me this technology that I fell in love with and found fascinating. The technology was called Bitcoin. At that stage in life I had a $1000 saved up, solely a gift from my Grandma to use for my scholarship fund. It did not go to my scholarship fund. I asked my brother to help me put it into Bitcoin at $12 because I knew it would be huge in someway. At that point I had about a 100 bitcoins. I continued to do ‘day trading’ buying low and selling high over the coming years as well and reinvesting the money. Fast forward to when I was 14 in high school I was not enjoying school. I was in a small town in Idaho living on a llama farm. So the quality of the school system, was let’s say, not the highest grade. I found the classes to be boring, valuable to some people, but at least for me boring and teaching me in a way that didn’t make sense to me. Lessons that did not seem applicable in my life. My teachers would constantly criticize people in the classroom. Especially me. One teacher told me to drop out and work at McDonald's because that was all I would amount to for the rest of my life. Another would force us to read other student’s grades out to the rest of the class to shame them for failing. Another roasted me (me in particular) for the full hour of class. No teaching. It was literally the “Roast of Erik Finman”. Which now seems kind of funny actually but still very bad to do. I went to a summer program to prepare me for the next year and found the best teacher ever in my life that changed my life who was from the UK. I got an A+ in advanced physics when I got a C- in basic physics the previous year. With that knowledge. Since I didn’t have access to good teachers in my small town in Idaho. I wanted to fix it. So I learned how to code and created an educational website that would allow you to connect with Tutors/Teachers/Mentors online over video chat to teach you any subject you wanted to learn. You could search for Spanish. And find someone to teach you from Ecuador. You could type in programming and you’d find a CS college student that is trying to pay tuition by doing this on the side. Or a retired expert who is a veteran in his field that just wants to impart his knowledge onto others. It became very popular in the local community! I told my teachers about it, but they did not like it because it felt like competition. Maybe they thought they might have to do better? At this point I was 15 and this got some initial traction and I was using it to teach myself. I asked my parents to let me drop out of High School to focus on this because I was miserable in school. They agreed and were supportive, but they made a bet with me that I can drop out of High School, but I have to go to college if I don’t make a million dollars by the age 18. I agreed and I dropped out of High School to work on this. A little bit after I dropped out of High School, and I had traction with my project. Bitcoin was shooting up! It was going big! $800! $900! $1000!!!! So I sold a lot of my Bitcoins which resulted in me gaining a $100,000. I used that money to put into my business so I could hire more professional programmers and I moved to Silicon Valley. I even caught the attention of Alexis Ohanian of Reddit because his book at the time Without Their Permission is what got me started. He helped me in many ways! Fast forward to early 2015. Eventually I found a buyer for the companies code & technology in January 2015. The investor offered either $100,000 or 300 bitcoin, which had dropped in value at that time to a little more than $200 a coin. I took the lower cash value bitcoin deal because I believed it was the next big thing and an official buyout would’ve been very difficult for someone under 18 and it was good tax planning to use Bitcoin. Also continuing to do day trading on a daily basis. I used some of that money in the coming years to travel the world. Going to London, Dubai, Australia, and more! I used that to start a VR company using crowdfunding and that did well. I shipped all those out. It was incredible! Now I’m doing a satellite as part of a NASA award which is launching in November out of New Zealand! I'll probably do another post about this soon because it's so cool. Elon Musk has always been hero of mine. He's such a talented guy changing the world with Tesla and SpaceX. I'm a great admirer of his and respect him immensely. He's the closest we have yet to a real life Iron Man. But who knows maybe I'll beat him one day haha ;-) After all we stand on the shoulders of giants right? haha that's a big goal though and I say it as such. It’s been a fantastic few years! I’ve used that money to learn how to do a business, invest, and learn about the world! I didn’t do investing all the time and I used that money to build things that I thought were important! I haven’t done everything perfectly, no one has! I’ve made some humbling mistakes, but had lots of exciting successes! I’ve really launched my career in exciting ways and have met mentors that help me and advise me along the whole way! Which I’m so thankful for! I’ve learned so much outside the education system and have been so much happier. Although I’m unique, I’ve met many many people that weren’t satisfied and unhappy — ranging from students with the lowest and highest GPAs. My GPA was a 2.1 in school! And I’m happy I’m not going to College! College wasn’t for me but it was the ‘life path’ you are supposed to go on and I did not want to go nor felt it would’ve helped me too much in life — especially the $250,000 in debt! Or $249,000 with my scholarship fund if I had not used it on Bitcoin and my projects ;-) I really believe the education system needs to be reformed and I think technology is the way to do that. I think it’s wonderful how society allows you to be a ‘student’ so that you can learn for many years and that’s your full time job. The infrastructure would just ideally be much better so you could do that without being in sometimes a bad environment and crippling debt. I can say today that I own 403 bitcoins which is currently valued at $1,092,678.08 with the price per Bitcoin being at $2,711.36 plus some other money invested in other things. Can’t have all your eggs in one basket! So I won the bet! If you have any questions let me know! And if you want any advice on cryptocurrency or your own educational route, or anything else let me know! Also on reddit! People have made Pepe memes of me! I feel like I've finally made it: http://imgur.com/gallery/06dWK If you want to keep updated with everything I’m doing! Follow me on twitter!

Why Verge Needs DigiShield NOW! And Why DigiByte Is SAFE!
Hello everyone, I’m back! Someone asked a question recently on what exactly happened to XVG – Verge and if this could be a problem for DGB – DigiByte - Here: DigiByte vs Verge It was a great question and there have been people stating that this cannot be a problem for us because of DigiShield etc… with not much explanation after that. I was curious and did a bit more investigating to figure out what happened and why exactly it is that we are safe. So take a read.
Some Information on Verge
Verge was founded in 2014 with code based on DogeCoin, it was initially named DogeCoinDark, it later was renamed Verge XVG in 2016. Verge has 5 mining algorithms as does DigiByte. Those being:
However, unlike DigiByte those algorithms do not run side by side. On Verge one block can only be mined by a single algorithm at any time. This means that each algorithm takes turns mining the chain.
Prior to the latest fork there was not a single line of code that forced any algo rotation. They all run in parallel but of course in the end only one block can be accepted at given height which is obvious. After the fork algo rotation is forced so only 6 blocks with the same algo out of any 10 blocks can be accepted. - srgn_
Mining Verge and The Exploit
What happened then was not a 51% attack per say, but the attacker did end up mining 99% of all new blocks so in fact he did have power of over 51% of the chain. The way that Verge is mined allowed for a timestamp exploit. Every block that is mined is dependent on the previous blocks for determining the algorithm to be used (this is part of the exploit). Also, their mining difficulty is adjusted every block (which last 30 seconds also part of the exploit). Algorithms are not picked but in fact as stated previously compete with one another. As for difficulty:
Difficulty is calculated by a version of DGW which is based on timestamps of last 12 blocks mined by the same algo. - srgn_
This kind of bug is very serious and at the foundation of Verge’s codebase. In fact, in order to fix it a fork is needed, either hard fork or soft fork! What happened was that the hacker managed to change the time stamps on his blocks. He introduced a pair of false blocks. One which showed that the scrypt mining algorithm had been previously used, about 26 mins before, and then a second block which was mined with scrypt. The chain is set up so that it goes through the 5 different algorithms. So, the first false block shows the chain that the scrypt algorithm had been used in the recent past. This tricks it into thinking that the next algorithm to be used is scrypt. In this way, he was essentially able to mine 99% of all blocks.
Pairs of blocks are used to lower the difficulty but they need to be mined in certain order so they can pass the check of median timestamp of last 11 blocks which is performed in CBlock::AcceptBlock(). There is no tricking anything into thinking that the next algo should be x because there is no algo picking. They all just run and mine blocks constantly. There is only lowering the difficulty, passing the checks so the chain is valid and accepting this chain over chains mined by other algos. - segn_
Here is a snippet of code for what the time stamps on the blocks would look like:
SetBestChain: new best=00000000049c2d3329a3 height=2009406 trust=2009407 date=04/04/18 13:50:09 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=000000000a307b54dfcf height=2009407 trust=2009408 date=04/04/18 12:16:51 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=00000000196f03f5727e height=2009408 trust=2009409 date=04/04/18 13:50:10 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=0000000010b42973b6ec height=2009409 trust=2009410 date=04/04/18 12:16:52 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=000000000e0655294c73 height=2009410 trust=2009411 date=04/04/18 12:16:53 ProcessBlock: ACCEPTED (scrypt)
Here’s the first falsified block that was introduced into the XVG chain – Verge-Blockchain.info As you can see there is the first fake block with a time stamp of 13:50:09 for example and the next is set to 12:15:51, the following two blocks are also a fraudulent pair and note that the next block is set to 12:16:52. So essentially, he was able to mine whole blocks - 1 second per block!
This exploit was brought to public attention by ocminer on the bitcointalk forums. It seems the person was a mining pool administrator and noticed the problem after miners on the pool started to complain about a potential bug. What happened next was that Verge developers pushed out a “fix” but in fact did not really fix the issue. What they did was simply diminish the time frame in which the blocks can be mined. The attack still was exploitable and the attacker even went on to try it again! “The background is that the "fix" promoted by the devs simply won't fix the problem. It will just make the timeframe smaller in which the blocks can be mined / spoofed and the attack will still work, just be a bit slower.” - ocminer Ocminer then cited DigiShield as a real fix to the issue! Stating that the fix should also stipulate that a single algo can only be used X amount of times and not be dependent on when the algo was last used. He even said that DigiByte and Myriad had the same problems and we fixed them! He cited this github repo for DigiByte:
It seems that the reason that this exploit was so lucrative was because the difficulty adjustment parameters were not enough to reduce the rewards the attacker recieved. Had the rewards per block adjusted at reasonable rate like we do in DGB then at least the rewards would have dropped significantly per block. The attacker was able to make off with around 60 million Verge which equals about 3.6 million dollars per today’s prices. The exploit used by the attacker depended on the fact that time stamps could be falsified firstly and secondly that the difficulty retargeting parameters were inadequate. Let’s cover how DigiShield works more in detail. One of the DigiByte devs gave us this post about 4 years ago now, and the topic deserves revisiting and updates! I had a hard time finding good new resources and information on the details of DigiShield so I hope you’ll appreciate this review! This is everything I found for now that I could understand hopefully I get more information later and I’ll update this post. Let’s go over some stuff on difficulty first then I’ll try giving you a way to visualise the way these systems work. First you have to understand that mining difficulty changes over time; it has to! Look at Bitcoin’s difficulty for example – Bitcoin difficulty over the past five months. As I covered in another post (An Introduction to DigiByte Difficulty in Bitcoin is readjusted every 2016 blocks which each last about 10 mins each. This can play out over a span of 2 weeks, and that’s why you see Bitcoin’s difficulty graph as a step graph. In general, the hash power in the network increases over time as more people want to mine Bitcoin and thus the difficulty must also increase so that rewards are proportional. The problem with non-dynamic difficulty adjustment is that it allows for pools of miners and or single entities to come into smaller coins and mine them continuously, they essentially get “free” or easily mined coins as the difficulty has not had time to adjust. This is not really a problem for Bitcoin or other large coins as they always have a lot of miners running on their chains but for smaller coins and a few years ago in crypto basically any coin other than Bitcoin was vulnerable. Once the miners had gotten their “free coins” they could then dump the chain and go mine something else – because the difficulty had adjusted. Often chains were left frozen or with very high fees and slow processing times as there was not enough hash power to mine the transactions. This was a big problem in the beginning with DigiByte and almost even killed DogeCoin. This is where our brilliant developers came in and created DigiShield (first known as MultiShield). These three articles are where most of my information came from for DigiShield I had to reread a the first one a few times to understand so please correct me if I make any mistakes! They are in order from most recent to oldest and also in order of relevance.
DigiShield is a system whereby the difficulty for mining DigiByte is adjusted dynamically. Every single block each at 15 seconds has difficulty adjusted for the available hashing power. This means that difficulty in DigiByte is as close as we can get to real time! There are other methods for adjusting difficulty, the first being the Bitcoin/Litecoin method (a moving average calculated every X number of blocks) then the Kimoto Gravity Well is another. The reason that DigiShield is so great is because the parameters are just right for the difficulty to be able to rise and fall in proportion to the amount of hash power available. Note that Verge used a difficulty adjustment protocol more similar to that of DigiByte than Bitcoin. Difficulty was adjusted every block at 30 seconds. So why was Verge vulnerable to this attack? As I stated before Verge had a bug that allowed for firstly the manipulation of time stamps, and secondly did not adjust difficulty ideally. You have to try to imagine that difficulty adjustment chases hashing power. This is because the hashing power on a chain can be seen as the “input” and the difficulty adjustment as the corresponding output. The adjustment or output created is thus dependent on the amount of hashing power input. DigiShield was designed so that increases in mining difficulty are slightly harder to result than decreases in mining difficulty. This asymmetrical approach allows for mining to be more stable on DigiByte than other coins who use a symmetrical approach. It is a very delicate balancing act which requires the right approach or else the system breaks! Either the chain may freeze if hash power increases and then dumps or mining rewards are too high because the difficulty is not set high enough! If you’ve ever taken any physics courses maybe one way you can understand DigiShield is if I were to define it as a dynamic asymmetrical oscillation dampener. What does this mean? Let’s cover it in simple terms, it’s difficult to understand and for me it was easier to visualise. Imagine something like this, click on it it’s a video: Caravan Weight Distribution – made easy. This is not a perfect analogy to what DigiShield does but I’ll explain my idea. The input (hashing power) and the output (difficulty adjustment) both result in oscillations of the mining reward. These two variables are what controls mining rewards! So that caravan shaking violently back and forth imagine those are mining rewards, the weights are the parameters used for difficulty adjustment and the man’s hand pushing on the system is the hashing power. Mining rewards move back and forth (up and down) depending on the weight distribution (difficulty adjustment parameters) and the strength of the push (the amount of hashing power input to the system). Here is a quote from the dev’s article. “The secret to DigiShield is an asymmetrical approach to difficulty re-targeting. With DigiShield, the difficulty is allowed to decrease in larger movements than it is allowed to increase from block to block. This keeps a blockchain from getting "stuck" i.e., not finding the next block for several hours following a major drop in the net hash of coin. It is all a balancing act. You need to allow the difficulty to increase enough between blocks to catch up to a sudden spike in net hash, but not enough to accidentally send the difficulty sky high when two miners get lucky and find blocks back to back.” AND to top it all off the solution to Verge’s time stamp manipulation bug is RIGHT HERE in DigiShield again! This was patched and in Digishield v3 problems #7 Here’s a direct quote: “Most DigiShield v3 implementations do not get data from the most recent blocks, but begin the averaging at the MTP, which is typically 6 blocks in the past. This is ostensibly done to prevent timestamp manipulation of the difficulty.” Moreover, DigiShield does not allow for one algorithm to mine more than 5 blocks in a row. If the next block comes in on the same algorithm then it would be blocked and would be handed off to the next algorithm. DigiShield is a beautiful delicate yet robust system designed to prevent abuse and allow stability in mining! Many coins have adopted out technology!
Verge Needs DigiShield NOW!
The attacker has been identified as IDCToken on the bitcointalk forums. He posted recently that there are two more exploits still available in Verge which would allow for similar attacks! He said this: “Can confirm it is still exploitable, will not abuse it futher myself but fix this problem immediately I'll give Verge some hours to solve this otherwise I'll make this public and another unpatchable problem.” - IDCToken DigiShield could have stopped the time stamp manipulation exploit, and stopped the attacker from getting unjust rewards! Maybe a look at Verge’s difficulty chart might give a good idea of what 1 single person was able to do to a coin worth about 1 billion dollars.
Edit - Made a few mistakes in understanding how Verge is mined I've updated the post and left the mistakes visible. Nothing else is changed and my point still stands Verge could stand to gain something from adopting DigiShield! Hi, I hope you’ve enjoyed my article! I tried to learn as much as I could on DigiShield because I thought it was an interesting question and to help put together our DGB paper! hopefully I made no mistakes and if I did please let me know. -Dereck de Mézquita I'm a student typing this stuff on my free time, help me pay for school?

"Bitcoin consumes more energy than [insert country here]", "Bitcoin is DESTROYING the planet", "Bitcoin could cost us our green future" A deeper look into bullshit.
As you might have noticed there has been an explosion of mainstream media article about Bitcoin's energy consumption. I won't link these crap but here are the titles:
The guardian: "Bitcoin mining consumes more electricity a year than Ireland "
Express.co.uk "SHOCK CLAIM: Bitcoin is DESTROYING the planet and uses as much energy as DENMARK"
Vice: "Bitcoin Could Consume as Much Electricity as Denmark by 2020"
Mashable: "How to fix Bitcoin's energy-consumption problem"
CBS News:"Bitcoin mining consumes more energy than 159 countries"
Newscientist : "Bitcoin mining uses more energy than Ecuador – but there’s a fix"
CNN: "Bitcoin boom may be a disaster for the environment"
Bloomberg: "Bitcoin's Exorbitant Energy Costs May Prove to Be Biggest Risk"
The list goes on...
So what is the info? Where does it come from? How did they come up with it? Is it true? What is the info Wrapped in sensationalism, the info is the following:
energy consumption of the bitcoin network, which is responsible for verifying transactions made with the cryptocurrency, is 30.14TWh a year
Where does it come from Following direct links, or going through endless source circle of newspaper quoting one another, the source for absolutely all of these news article is the following website: https://digiconomist.net/bitcoin-energy-consumption The about section contains the following:
Digiconomist is a platform that provides in-depth analysis, opinions and discussions with regard to Bitcoin and other cryptocurrencies. The goal of Digiconomist is to cover any relevant financial, economic or regulatory cryptocurrency-related topic.
Additionally a quick look at the website shows a few things: 1. The website only talks about ETH and BTC 2. Outside of the blog posts it almost only talks about energy consumption (there is an ETH obituaries) 3. Blog posts started in march 2014 4. The domain was registered the 2014-07-03 5. No address, no country, no name, no foundation, no agency... Who are they? Disregarding the fact that it comes from a no name website the, info is right there with a nice graph and even a methodology explained with a pretty infochart. It almost looks to good for a blog about cryptos. How did the Bloomberg, ars technica and the like found this website? I do not know, but when they did a ready to use report for newspaper was there waiting for them. Also, the graph as an url embedded at the bottom: "bitcoinenergyconsumption.com" which interestingly enough is a redirect for Digiconomist. Also the bottom of the page on consumption has a list of news articles referring to this website for their sensationalist claims. How did they come up with it So as I said the methodology is there, and the result of it is there too:
Bitcoin's current estimated annual electricity consumption* (TWh) 32.53
So let's dive into the methodology on a step by step process, first of all, a further detailed methodology is shown here
First, calculate the "Annualized global mining revenues (USD)", the website says: $13,487,831,695 As of this writing, on fork.lol, the reward for BTC is around r = 240 000 USD per block. r * 6 * 24 * 365 = 12 614 400 000. This is the same order of magnitude, but not good enough. Including the BCH reward as well (17 639 as we speak) gives : C = 13 541 505 840 USD. Seems about right.
Calculate the mining operating cost "Annualized estimated global mining costs" : $1,626,480,051 This is easy, it is simply 60% of the previous number C * 0.6 = 8 124 903 504 USD ??? Ok this is weird, their number is not even 60%, it is more like 12%. So where is that number coming from?? Turns out this 60% assumption is not used at all in the calculation...
Disregard the previous step
Calculate the current total hashrate on the network: 14.12 ExaHashes/s at the time of these lines
Assume the following:
Since the marginal product of mining is equal to the number of Bitcoins received per unit of mining effort, it would thus be expected that miners will either add more hashrate if the resulting revenue exceeds associated electricity costs, or reduce the hashrate once electricity costs start exceeding the revenue per hash. This also means that it is expected that the total network of Bitcoin miners is always mining at the calculate-able break-even efficiency. The break-even efficiency for Bitcoin mining can simply be calculated as: W per GH/s=(price∙BTC/day)/(price per kWh ∙ 24hrday)
In layman terms, this means that they assume that the number of miners is always the exact amount for break even. This is a fair assumption. The formula that follows it make no sense without the context it came with in that working paper. A quick look at this document shows concerning mathematical mistakes... I have tried for far too long, I cannot reproduce any of their numbers... So is it true? No These numbers are not reproducible, they make no sense and calculated using a dubious paper by some professor of "social research". I assume he is also the owner of the website because his name appears way too often in there...The university where he studies has a nice wikipedia page:
The New School is a private non-profit research university centered in Manhattan, New York City, USA, located mostly in Greenwich Village. It was founded in 1919 as an institution dedicated to academic freedom and intellectual inquiry, serving as a home for progressive thinkers.
The real estimation This is actually pretty straight forward. The maximum ever reached in hash rate was 16.5 exahashes/s according to fork.lol. This is equivalent to 1.18 million S9 ant miner at 14 TH/s. Assuming everyone suck and they all have old hardware with crappy PSU. Let's say each S9 consumes 2000W. This is a 17520000 Wh per year per miner, which yields 20.67 TWh. So peak production with very negatives assumptions yields a number 40% lower... General critic Deriving consumption from the mining revenue is purely ludicrous. No including the fees in the mining revenue calculation is also ludicrous. If your numbers are not reproducible, they are worthless.
Adoption. I keep hearing that BTC is like gold and you don't use gold for purchases but whats the point of this store of wealth if problem 1 is lingering over us?
If I do have any more questions I will update this list. please do not take this as an insult to BTC. I am truly raising these concerns to get answers and help the community. I have also not listed any coins that I own and have not shilled anything. I truly hope crypto disrupts the world banking system and I am glad you are all a part of this revolution. If you look at this way, our investment means more than just gains.

THE HEADLINE: As we reflect upon on 2017, it is probably fair to make a bold statement that it has been a phenomenal leap forward for the trio of Blockchain, Cryptocurrency and the ICO. Here is why: • Bitcoin (the most popular cryptocurrency and once defamed as a ‘hyper-coin’) hit another all-time high passing $8000. Today, Bitcoin is worth about $50 billion and has been accepted under the law and tax frameworks of Canada, Australia, and Japan. • Ethereum network (platform) and its own fuel ( coin) Ether has appreciated more than 2,800% since it was launched in 2015. • Underlying Blockchain technology is no more a hype, it is disrupting every industry through its secure public ledger • ICOs have raked in over 3.6 Billion Dollars, the largest ICO in 2017 has been Filecoin raising over 257 Million Dollars. This is the just beginning of the ICO revolution where IPOs and traditional stock exchanges are going to become a thing in the past. Let’s admit it. We either have a tribe of people who love the whole concept of decentralized and autonomous Peer to Peer network completely secure and away from the control of the regulators and bureaucrats OR you still belong to the other tribe, you think Cryptocurrencies are dark alleys and ‘good’ people should stay away lurking in these areas. We respect views on either side and we would like to just attempt to demystify few basic practical concepts here that one should know if you are new to this so called “Crypto Tribe”. EVOLUTION OF CRYPTO AND BITCOIN The first internet currency, known as DigiCash, was created by David Chaum and is said to have its origin from Netherlands. This was arguably the first attempt, but the idea failed and the company went bankrupt in 1998. Keeping up with the trend PayPal ( one of the global leaders in Payments Industry) was next to follow-up and became highly successful, but did not create an actual cryptocurrency. So history was made when the first real cryptocurrency, Bitcoin, was invented by someone went by the pseudonym Satoshi Nakamoto in 2008 and went online in 2009. There has been several failed attempts to identify this person. This ground breaking and revolutionary makes it possible to take to replace central authorities, government, watchdogs bureaucrats and politicians with the decentralized blockchain, and take power away from Wall Street. Bitcoin has already broken its own records several times since it started. The chart below will obviously blow your mind if you have not tracked Bitcoin recently. In less than 8 years Bitcoin has given over 8000% return. From 0 to 8000 USD per coin. And ofcourse there are talks of the next bubble and market for Bitcoin crashing down anytime. Really? Let’s address them a bit later in this paper. The legacy of crypto goes back to the days of World War II when cryptographic systems were devised to securely transmit messages between various parties. All has happened is the technology and evolution has progressed since with the advancement of Computer systems and underlying hardware and software. We hence now have a very powerful system on the network for anyone to harness. WHAT IS BLOCKCHAIN? A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. A blockchain can serve as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way not in citation given. For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. And that is the latest Wikipedia definition for you. However, in layman terms, what is the best way to explain it? Let’s think of a used-car for a purpose of illustration. The new buyer would like to ensure that the car is genuinely owned by the seller, that the car servicing history is fully up to date and any major issues has been picked up transparently in the car service history. In real world that may not be possible always. Let’s take another example. We go to our regular family doctor ( GP). Their computer has full history of our health records from illness, diagnosis, medicines and treatments. If we go to another city, it would be very important that the new doctor has full information as well. Sometimes things do not work that way. And this is where the power of Blockchain comes into play. Blockchain is like a decentralized and distributed computer or electronic database existing on multiple computers at the same time ( but not owned by any big company specifically atall). The database keeps growing continuously as new sets of key information, or ‘blocks’, are added to it. Each block contains a very important information - timestamp and a link to the previous block. These then actually form a chain, everyone in the network gets a copy of the whole database but the database is not managed by any particular body, person or corporation. Entire old block are preserved forever and new blocks are added to the ledger irreversibly, making it next to impossible to manipulate by faking documents, transactions and other information. And yes, hackers know this and they have no interest in this area as they cannot manipulate here. They will most likely to continue to pry on large private businesses and public sector for ransom not Blockchain for a very long time or may be forever! It is also worthwhile mentioning here that since Blockchain runs on a public network, there are concept of ‘mining’ and rewards to the ‘miners’. In simple terms, people are rewarded for allowing their computers to be used for harnessing the ‘processing power’ of Block execution. Every new transaction on a block ofcourse needs to be executed. Now that you have got a bit of history of the whole Cryptocurrency and Block chain technology mumbo-jumbo, you may be thinking what about another term ICO which everyone keeps talking at the Pub and every now and then on various websites and journals. What are ICO really? Let’s get that out of way as possible. THE DAWN OF INITIAL COIN OFFERING ( aka ICO) You are probably already familiar with the traditional stock market and the concept of Initial Public Offering ( IPO), so we will not go too deep into it. But in a nutshell, until recently businesses have raised money from the public by listing their businesses on the famous stock exchanges. Ofcourse, it is not possible for Mr. John Smith from a little village selling his home made secret strawberry jam globally until he has deep pockets. Neither he can even dream of getting his business listed on a stock exchange to raise cash from public. Hence listing businesses and raising cash has remain the forte of the big and bold with the backing of Venture Capitalist firms, Private Equity firms and the Brokers. And ofcourse there has been the means of the “Angel Investor” who would give cash by taking significant equity stake in a business started by the entrepreneur with their blood and sweat. Then emerged the concept of “Crowd Funding”. Online project funding websites like kickstarter, crowdcube, seedrs emerged. They allowed entrepreneurs to request for funds from the public. But these methods have raised limited funds, grossly regulated by the local authorities and not everyone could raise money from here. So you may ask what IPOs and Crowdfunding has anything to do with Blockchain technology and ICOs? Well what if we say that there are investors out there who believe in the disruptive nature of Blockchain Technology and are also early adopters of cryptocurrency such as bitcoin. Then there is whole liberal aspect of the unregulated market which makes the whole world shift towards a very different perspective. Now an entrepreneur could actually raise money for building their business from very early stages ( sometimes from just a concept level) and accepting the money not in traditional currency ( aka Fiat currency) but Cryptocurrency. And further, each of these new projects could even release their own version or token of an underlying cryptocurrency or digital currency. Now that’s sexy and awesome isn’t it? Well, we are not going to down the route here to inform the readers it is good or bad practice in this paper. We will leave that opinion formation to yourself. Now that you got a high level understanding of ICOs, the next thing you may want to know is that it is pretty straight forward to invest into an ICO ( we will cover more in this paper later). But you need to understand is ICOs just like an IPO are for short duration. Usually they last for few weeks (typically 4 weeks). You get bonus Tokens or the crypto coin to invest early. Once the ICO minimum target is reached ( Softcap) the coins gets listed on the CoinExchange and they start trading. Coinexchange? What are these then? Quite simple, just go back to the analogy between a traditional stock and traditional stock exchange. Very simple concept really. How you buy, sell and do the nitty-gritty just differs. Since there are no brokers or regulators involved here. The whole process is really simple and quick. It may worthwhile sharing a quick snapshot of the ICO market worldwide: It is mind boggling to see that new businesses in really concept stages are raising more money than traditional businesses in just few hours of ICOs getting listed. Obviously this is really bothering lot of people in high ranking posts. We are not here to again debate who is right or wrong here. What we essentially want you to understand is some of these ICOs are really shaping the next wave of revolution. How many of you believed that a Smart Phone with a so called ‘mobile app’ would be worth billion of dollar? Look at Uber, Alibaba, Airbnb, Facebook. Why no one complains about their valuation? May be because these businesses have backing of very large venture capitalists, Private Equity firms? But who runs these VCs and PE firms? Do you really need 70 Billion Dollars to run a Taxi mobile app? We honestly do not know. But what we know for sure is disruptive technologies and businesses built on top of them always have an edge. And then you combine the technology and handover its power to the people you create a social eco-system that is so strong and powerful that it can override and form its own status. And that is what is happening with the ICOs. People are investing into their trust and belief. Now that’s more powerful than any single bank, government or institution ! If you have followed this paper so far, you should have started to get an idea of what is really going on here about the trio – Blockchain Technology, Cryptocurrencices and ICO. However, I am sure you still have may have zillion questions about how you do certain things. Let us try give you answers to some of the most common questions asked by those who really want to get involved. FREQUENTLY ASKED QUESTIONS Question 1: I am interested in buying and investing into a Cryptocurrency. Should I buy Bitcoin? Answer: Bitcoin is one of the most popular cryptocurrency. We can not advise you anything specific as you need to do your own research. The number of cryptocurrencies available over the internet as of 6 November 2017 was over 1172 and growing. A new cryptocurrency can be created at any time. By market capitalization, Bitcoin is currently (2017-08-19) the largest blockchain network, followed by Ethereum, Bitcoin Cash, Ripple and Litecoin. Question 2: I am interested in investing into a ICO that what research and due-diligence I need to do ? Answer: We are glad that you mentioned the two magical words “research” and “due-diligence”. That is the most important golden nugget that we want you to take-away from this paper. Never-ever invest into a ICO unless you have researched it for how long it takes to build a strong opinion. Here is a good article that gives some really good tips. One quick tip from us would be ensure that Team is really strong and they are genuine people. http://mashable.com/2017/10/25/survive-ico/#CDVyGFJOiiqF Question 3: How do I find out about upcoming ICOs and useful related news and press releases? Answer: There are plenty of websites now that can give you early headsup and keep you well informed. Our favourites are ICOBENCH, COINDESK, ICOALERT. Question 4: Where can we buy and sell ICO and cryptocurrencies? Answer: If you are newbie, it may be a good idea to ask someone in your close network to guide you. There are lots of information and instructional video available on Youtube and other social media network and blogs. Sometimes too much information leads to confusion. You may also want to look into tutorials and training available at UDEMY.COM. But please steer away from self-proclaimed gurus. Do not buy any quick rich scheme related courses and scams. We have found that for beginners https://www.myetherwallet.com/ or https://parity.io/ are good starting point for Ethereum Blockchain related transactions. Question 5: When is a good time to invest in Cryptocurrency? Answer: We wish we had the crystal ball to give you the answer. If we had this crystal ball in 2009 ( when Bitcoin started), we would be very rich people right now. But with a bit of research and education, you can master this. You need to make your own decision when is the right time for you. Question 6: ICO and Cryptocurrency are all hype and dodgy? Answer: We are assuming you are a beginner, you do not know enough about Blockchain technology and how it works, you possibly have not spent enough time learning and tracking about cryptocurrencies. There is also a possibility you have never invested in a cryptocurrency or ICO. Or possibly you invested in a ICO that was a scam. You possibly could be a sophisticated investor in property, traditional shares, gold, forex and much more. But may be you do not want to know any more about Digital currencies or Technology as it is not your “comfort zone”. So the question is how much of homework you have done to assess if this whole concept for you is really interesting or completely ruled out? The decision end of the day is yours.

Of Wolves and Weasels - Day 109 - Weekly Wrapup #9
Hey all! GoodShibe here! Here's your Weekly Wrap-up of what went on in the community this week. Announcements
DOGECON SF was a great success! Put together in just over a week - which in itself is so Dogecoin that it's scary - our very first coinference has gotten us some great attention!
hfn64 made "What is Dogecoin?" - a brilliant, professional, welcome and explanation of who we are and what we do best. Use this video to help explain the concept to newbies. Try to get it used in the news! (Original Intro thread)
Did I miss something? I'm sure I did! Please let me know in the comments and I'll add it! Also of note, I've seen almost no new Dogecoin businesses coming forward in the last week. Something worth mentioning! It's 8:27AM EST and we're at 74.57% of DOGEs found. Our Global Hashrate is spiking from ~68 to 77 Gigahashes per second and our Difficulty is bouncing between ~964 and ~1305. Get out there and mine, my friends! The Halvening part 2 happens tomorrow! As always, I appreciate your support! GoodShibe
Hey all, GoodShibe here! One of the realities about cryptocurrency right now - one of the reasons I've been trying to bring back some of the original hype - is that pretty much everything is down. And not just 'down' but consistently down, over a long period of time. Sure, there's some jockeying for position in the top 10, but no one's really 'growing'. If you look past the top 10... well... pumps and dumps, in various stages, pretty much as far as the eye can see. And that's definitely part of it. But the reality is that cryptocurrency as a whole is stagnating. If you think back to a year ago, when things were really hot they were hot because Bitcoin had a lot of attention -- which meant that pretty much everything to do with Crypto had a lot of attention. And even then, it was because most people were looking for the next Bitcoin to buy into and cash out quick. But Bitcoin falling off a cliff in China put a pretty solid end to that. Which is why I don't think we'll see another rise like Bitcoin had ever again, honestly. Because that heat wasn't built off of fundamentals or anything remotely tangible. It was a perfect storm of hype - a hyperstorm - fueled by that major rush of overnight millionaires. Lots of people who'd sorta-kinda paid attention when Bitcoin was worth pennies, maybe bought or mined a few hundred or thousand and had it kicking around on an old hard drive. Everyone loves an overnight millionaire story - and Bitcoin, at it's $1000-ish-per-coin peak was churning them out by the day. People digging through the trash to find old hard drives suddenly worth millions. Overnight millionaires buying Teslas with Bitcoin. That stuff, my friends, is the creme-de-la-creme of Hype. And it's gone. And with it's departure, a good, what, 90% of the marketcap of cryptocurrency as a whole? There have been real attempts to re-create it, lots of 'Bitcoin challengers' stepping into the ring only to send people home penniless as Wolves and Weasels waded deep into the pool. cough Paycoin cough But the reality is that the folks who are paying attention to Bitcoin now are those who are heavily invested in 'real' money... and they're looking for ways to co-opt Bitcoin's tech without having to actually use Bitcoin. What I'm trying to say here is that preaching to the choir isn't going to work anymore -- most of it has packed up and gone home. Only the true diehards are left now, the people who believe, with the newbies who are arriving being mostly those who are willing to look past all the scandals and black market stuff and negative press. Dogecoin has an incredibly important part to play in the next wave of cryptocurrency by reaching out to new people, to people who've never heard of Crypto, by making it clear that it's not an 'overnight rich' thing, but an invaluable tool for positive change. And we're in an amazing position to take action: We have an active, fun community. We have some world-class, hard-working devs. We've never had any significant ties to drugs or illegal activities. Heck, the biggest strike that was ever landed against us is that we're 'silly' or a 'joke'. Well, take an honest look at the world around us right now, at the headlines, and tell me that folks couldn't use a laugh! THIS is why I'm pushing for us to get hyped again, why I want us to work on calling back our artists, why I've kept on encouraging our DOGEconomy to grow. Because it's not just about bringing new people to Dogecoin, it's about giving them things to do, giving them tools that they can use once they get here. I need you to get hyped. To believe. Because I have a plan for this summer, but I need your help. This summer, we're going to focus on bringing in a whole new bunch of Shibes. And, if we play our cards right, it's going to be awesome! What do you say, my friends, are you with me? It's 7:27AM EST and we've found 98.83% of our first 100 Billion DOGEs! Our Global Hashrate is holding at ~1190 to ~1200 Gigahashes per second and our Difficulty is up from ~15366 to ~16175. As always, I appreciate your support! GoodShibe Please take 10 seconds or so to vote for Josh Wise!
But if Bitcoin mining power spreads a bit more evenly around the globe, this threat would be diminished. Over the past couple of years, China has been quite hostile towards Bitcoin and cryptocurrencies in general, at one point shutting down all cryptocurrency exchanges in the country, and undertaking or threatening numerous other measures to stifle cryptocurrency-related activities.
