The History of Bitcoin - 12 Key Dates [2020]

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.
Bitcoin:
The very first, and the highest ever valued, mass-market open source and decentralized cryptocurrency and digital payment system that runs on a worldwide peer to peer network. It operates independently of any centralized authorities
Bitconnect:

He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.
Bull market:
A market that Cryptos are going up.

Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.

Introduction
Proof of Work (commonly abbreviated to PoW) is a mechanism for preventing double-spends. Most major cryptocurrencies use this as their consensus algorithm. That’s just what we call a method for securing the cryptocurrency’s ledger.
Proof of Work was the first consensus algorithm to surface, and, to date, remains the dominant one. It was introduced by Satoshi Nakamoto in the 2008 Bitcoin white paper, but the technology itself was conceived long before then.
Adam Back’s HashCash is an early example of a Proof of Work algorithm in the pre-cryptocurrency days. By requiring senders to perform a small amount of computing before sending an email, receivers could mitigate spam. This computation would cost virtually nothing to a legitimate sender, but quickly add up for someone sending emails en masse.

What is a double-spend?

A double-spend occurs when the same funds are spent more than once. The term is used almost exclusively in the context of digital money — after all, you’d have a hard time spending the same physical cash twice. When you pay for a coffee today, you hand cash over to a cashier who probably locks it in a register. You can’t go to the coffee shop across the road and pay for another coffee with the same bill.
In digital cash schemes, there’s the possibility that you could. You’ve surely duplicated a computer file before — you just copy and paste it. You can email the same file to ten, twenty, fifty people.
Since digital money is just data, you need to prevent people from copying and spending the same units in different places. Otherwise, your currency will collapse in no time.
For a more in-depth look at double-spending, check out Double Spending Explained.

Why is Proof of Work necessary?

If you’ve read our guide to blockchain technology, you’ll know that users broadcast transactions to the network. Those transactions aren’t immediately considered valid, though. That only happens when they get added to the blockchain.
The blockchain is a big database that every user can see, so they can check if funds have been spent before. Picture it like this: you and three friends have a notepad. Anytime one of you wants to make a transfer of whatever units you’re using, you write it down — Alice pays Bob five units, Bob pays Carol two units, etc.
There’s another intricacy here — each time you make a transaction, you refer to the transaction where the funds came from. So, if Bob was paying Carol with two units, the entry would actually look like the following: Bob pays Carol two units from this earlier transaction with Alice.
Now, we have a way to track the units. If Bob tries to make another transaction using the same units he just sent to Carol, everyone will know immediately. The group won’t allow the transaction to be added to the notepad.
Now, this might work well in a small group. Everyone knows each other, so they’ll probably agree on which of the friends should add transactions to the notepad. What if we want a group of 10,000 participants? The notepad idea doesn’t scale well, because nobody wants to trust a stranger to manage it.
This is where Proof of Work comes in. It ensures that users aren’t spending money that they don’t have the right to spend. By using a combination of game theory and cryptography, a PoW algorithm enables anyone to update the blockchain according to the rules of the system.

How does PoW work?

Our notepad above is the blockchain. But we don’t add transactions one by one — instead, we lump them into blocks. We announce the transactions to the network, then users creating a block will include them in a candidate block. The transactions will only be considered valid once their candidate block becomes a confirmed block, meaning that it has been added to the blockchain.
Appending a block isn’t cheap, however. Proof of Work requires that a miner (the user creating the block) uses up some of their own resources for the privilege. That resource is computing power, which is used to hash the block’s data until a solution to a puzzle is found.
Hashing the block’s data means that you pass it through a hashing function to generate a block hash. The block hash works like a “fingerprint” — it’s an identity for your input data and is unique to each block.
It’s virtually impossible to reverse a block hash to get the input data. Knowing an input, however, it’s trivial for you to confirm that the hash is correct. You just have to submit the input through the function and check if the output is the same.
In Proof of Work, you must provide data whose hash matches certain conditions. But you don’t know how to get there. Your only option is to pass your data through a hash function and to check if it matches the conditions. If it doesn’t, you’ll have to change your data slightly to get a different hash. Changing even one character in your data will result in a totally different result, so there’s no way of predicting what an output might be.
As a result, if you want to create a block, you’re playing a guessing game. You typically take information on all of the transactions that you want to add and some other important data, then hash it all together. But since your dataset won’t change, you need to add a piece of information that is variable. Otherwise, you would always get the same hash as output. This variable data is what we call a nonce. It’s a number that you’ll change with every attempt, so you’re getting a different hash every time. And this is what we call mining.
Summing up, mining is the process of gathering blockchain data and hashing it along with a nonce until you find a particular hash. If you find a hash that satisfies the conditions set out by the protocol, you get the right to broadcast the new block to the network. At this point, the other participants of the network update their blockchains to include the new block.
For major cryptocurrencies today, the conditions are incredibly challenging to satisfy. The higher the hash rate on the network, the more difficult it is to find a valid hash. This is done to ensure that blocks aren’t found too quickly.
As you can imagine, trying to guess massive amounts of hashes can be costly on your computer. You’re wasting computational cycles and electricity. But the protocol will reward you with cryptocurrency if you find a valid hash.
Let’s recap what we know so far:
  • It’s expensive for you to mine.
  • You’re rewarded if you produce a valid block.
  • Knowing an input, a user can easily check its hash — non-mining users can verify that a block is valid without expending much computational power.
So far, so good. But what if you try to cheat? What’s to stop you from putting a bunch of fraudulent transactions into the block and producing a valid hash?
That’s where public-key cryptography comes in. We won’t go into depth in this article, but check out What is Public-Key Cryptography? for a comprehensive look at it. In short, we use some neat cryptographic tricks that allow any user to verify whether someone has a right to move the funds they’re attempting to spend.
When you create a transaction, you sign it. Anyone on the network can compare your signature with your public key, and check whether they match. They’ll also check if you can actually spend your funds and that the sum of your inputs is higher than the sum of your outputs (i.e., that you’re not spending more than you have).
Any block that includes an invalid transaction will be automatically rejected by the network. It’s expensive for you to even attempt to cheat. You’ll waste your own resources without any reward.
Therein lies the beauty of Proof of Work: it makes it expensive to cheat, but profitable to act honestly. Any rational miner will be seeking ROI, so they can be expected to behave in a way that guarantees revenue.

Proof of Work vs. Proof of Stake

There are many consensus algorithms, but one of the most highly-anticipated ones is Proof of Stake (PoS). The concept dates back to 2011, and has been implemented in some smaller protocols. But it has yet to see adoption in any of the big blockchains.
In Proof of Stake systems, miners are replaced with validators. There’s no mining involved and no race to guess hashes. Instead, users are randomly selected — if they’re picked, they must propose (or “forge”) a block. If the block is valid, they’ll receive a reward made up of the fees from the block’s transactions.
Not just any user can be selected, though — the protocol chooses them based on a number of factors. To be eligible, participants must lock up a stake, which is a predetermined amount of the blockchain’s native currency. The stake works like bail: just as defendants put up a large sum of money to disincentivize them from skipping trial, validators lock up a stake to disincentivize cheating. If they act dishonestly, their stake (or a portion of it) will be taken.
Proof of Stake does have some benefits over Proof of Work. The most notable one is the smaller carbon footprint — since there’s no need for high-powered mining farms in PoS, the electricity consumed is only a fraction of that consumed in PoW.
That said, it has nowhere near the track record of PoW. Although it could be perceived as wasteful, mining is the only consensus algorithm that’s proven itself at scale. In just over a decade, it has secured trillions of dollars worth of transactions. To say with certainty whether PoS can rival its security, staking needs to be properly tested in the wild.

Closing thoughts

Proof of Work was the original solution to the double-spend problem and has proven to be reliable and secure. Bitcoin proved that we don’t need centralized entities to prevent the same funds from being spent twice. With clever use of cryptography, hash functions, and game theory, participants in a decentralized environment can agree on the state of a financial database.

Craig Steven Wright is Satoshi Nakamoto

A couple of years ago in the early months of the 2017, I published a piece called Abundance Via Cryptocurrencies (https://www.reddit.com/C\_S\_T/comments/69d12a/abundance\_via\_cryptocurrencies/) in which I kind of foresaw the crypto boom that had bitcoin go from $1k to $21k and the alt-coin economy swell up to have more than 60% of the bitcoin market capitalisation. At the time, I spoke of coming out from “the Pit” of conspiracy research and that I was a bit suss on bitcoin’s inception story. At the time I really didn’t see the scaling solution being put forward as being satisfactory and the progress on bitcoin seemed stifled by the politics of the social consensus on an open source protocol so I was looking into alt coins that I thought could perhaps improve upon the shortcomings of bitcoin. In the thread I made someone recommended to have a look at 4chan’s business and finance board. I did end up taking a look at it just as the bull market started to really surge. I found myself in a sea of anonymous posters who threw out all kinds of info and memes about the hundreds, thousands, tens of thousands of different shitcoins and why they’re all going to have lambos on the moon. I got right in to it, I loved the idea of filtering through all the shitposts and finding the nuggest of truth amongst it all and was deeply immersed in it all as the price of bitcoin surged 20x and alt coins surged 5-10 times against bitcoin themselves. This meant there were many people who chucked in a few grand and bought a stash of alt coins that they thought were gonna be the next big thing and some people ended up with “portfolios” 100-1000x times their initial investment.
To explain what it’s like to be on an anonymous business and finance board populated with incel neets, nazis, capitalist shit posters, autistic geniuses and whoever the hell else was using the board for shilling their coins during a 100x run up is impossible. It’s hilarious, dark, absurd, exciting and ultimately addictive as fuck. You have this app called blockfolio that you check every couple of minutes to see the little green percentages and the neat graphs of your value in dollars or bitcoin over day, week, month or year. Despite my years in the pit researching conspiracy, and my being suss on bitcoin in general I wasn’t anywhere near as distrustful as I should have been of an anonymous business and finance board and although I do genuinely think there are good people out there who are sharing information with one another in good faith and feel very grateful to the anons that have taken their time to write up quality content to educate people they don’t know, I wasn’t really prepared for the level of organisation and sophistication of the efforts groups would go to to deceive in this space.
Over the course of my time in there I watched my portfolio grow to ridiculous numbers relative to what I put in but I could never really bring myself to sell at the top of a pump as I always felt I had done my research on a coin and wanted to hold it for a long time so why would I sell? After some time though I would read about something new or I would find out of dodgy relationships of a coin I had and would want to exit my position and then I would rebalance my portfolio in to a coin I thought was either technologically superior or didn’t have the nefarious connections to people I had come across doing conspiracy research. Because I had been right in to the conspiracy and the decentralisation tropes I guess I always carried a bit of an antiauthoritarian/anarchist bias and despite participating in a ridiculously capitalistic market, was kind of against capitalism and looking to a blockchain protocol to support something along the lines of an open source anarchosyndicalist cryptocommune. I told myself I was investing in the tech and believed in the collective endeavour of the open source project and ultimately had faith some mysterious “they” would develop a protocol that would emancipate us from this debt slavery complex.
As I became more and more aware of how to spot artificial discussion on the chans, I began to seek out further some of the radical projects like vtorrent and skycoin and I guess became a bit carried away from being amidst such ridiculous overt shilling as on the boards so that if you look in my post history you can even see me promoting some of these coins to communities I thought might be sympathetic to their use case. I didn’t see it at the time because I always thought I was holding the coins with the best tech and wanted to ride them up as an investor who believed in them, but this kind of promotion is ultimately just part of a mentality that’s pervasive to the cryptocurrency “community” that insists because it is a decentralised project you have to in a way volunteer to inform people about the coin since the more decentralised ones without premines or DAO structures don’t have marketing budgets, or don’t have marketing teams. In the guise of cultivating a community, groups form together on social media platforms like slack, discord, telegram, twitter and ‘vote’ for different proposals, donate funds to various boards/foundations that are set up to give a “roadmap” for the coins path to greatness and organise marketing efforts on places like reddit, the chans, twitter. That’s for the more grass roots ones at least, there are many that were started as a fork of another coin, or a ICO, airdrop or all these different ways of disseminating a new cryptocurrency or raising funding for promising to develop one. Imagine the operations that can be run by a team that raised millions, hundreds of millions or even billions of dollars on their ICOs, especially if they are working in conjunction with a new niche of cryptocurrency media that’s all nepotistic and incestuous.
About a year and a half ago I published another piece called “Bitcoin is about to be dethroned” (https://www.reddit.com/C\_S\_T/comments/7ewmuu/bitcoin\_is\_about\_to\_be\_dethroned/) where I felt I had come to realise the scaling debate had been corrupted by a company called Blockstream and they had been paying for social media operations in a fashion not to dissimilar to correct the record or such to control the narrative around the scaling debate and then through deceit and manipulation curated an apparent consensus around their narrative and hijacked the bitcoin name and ticker (BTC). I read the post again just before posting this and decided to refer to it to to add some kind of continuity to my story and hopefully save me writing so much out. Looking back on something you wrote is always a bit cringey especially because I can see that although I had made it a premise post, I was acting pretty confident that I was right and my tongue was acidic because of so much combating of shills on /biz/ but despite the fact I was wrong about the timing I stand by much of what I wrote then and want to expand upon it a bit more now.
The fork of the bitcoin protocol in to bitcoin core (BTC) and bitcoin cash (BCH) is the biggest value fork of the many that have occurred. There were a few others that forked off from the core chain that haven’t had any kind of attention put on them, positive or negative and I guess just keep chugging away as their own implementation. The bitcoin cash chain was supposed to be the camp that backed on chain scaling in the debate, but it turned out not everyone was entirely on board with that and some players/hashpower felt it was better to do a layer two type solution themselves although with bigger blocks servicing the second layer. Throughout what was now emerging as a debate within the BCH camp, Craig Wright and Calvin Ayre of Coin Geek said they were going to support massive on chain scaling, do a node implementation that would aim to restore bitcoin back to the 0.1.0 release which had all kinds of functionality included in it that had later been stripped by Core developers over the years and plan to bankrupt the people from Core who changed their mind on agreeing with on-chain scaling. This lead to a fork off the BCH chain in to bitcoin satoshis vision (BSV) and bitcoin cash ABC.

The premise for this post is that Craig S Wright was Satoshi Nakamoto. It’s an interesting premise because depending upon your frame of reference the premise may either be a fact or to some too outrageous to even believe as a premise. Yesterday it was announced via CoinGeek that Craig Steven Wright has been granted the copyright claim for both the bitcoin white-paper under the pen name Satoshi Nakamoto and the original 0.1.0 bitcoin software (both of which were marked (c) copyright of satoshi nakamoto. The reactions to the news can kind of be classified in to four different reactions. Those who heard it and rejected it, those who heard it but remained undecided, those who heard it and accepted it, and those who already believed he was. Apparently to many the price was unexpected and such a revelation wasn’t exactly priced in to the market with the price immediately pumping nearly 100% upon the news breaking. However, to some others it was a vindication of something they already believed. This is an interesting phenomena to observe. For many years now I have always occupied a somewhat positively contrarian position to the default narrative put forward to things so it’s not entirely surprising that I find myself in a camp that holds the minority opinion. As you can see in the bitcoin dethroned piece I called Craig fake satoshi, but over the last year and bit I investigated the story around Craig and came to my conclusion that I believed him to be at least a major part of a team of people who worked on the protocol I have to admit that through reading his articles, I have kind of been brought full circle to where my contrarian opinion has me becoming somewhat of an advocate for “the system’.
https://coingeek.com/bitcoin-creator-craig-s-wright-satoshi-nakamoto-granted-us-copyright-registrations-for-bitcoin-white-paper-and-code/

When the news dropped, many took to social media to see what everyone was saying about it. On /biz/ a barrage of threads popped up discussing it with many celebrating and many rejecting the significance of such a copyright claim being granted. Immediately in nearly every thread there was a posting of an image of a person from twitter claiming that registering for copyright is an easy process that’s granted automatically unless challenged and so it doesn’t mean anything. This was enough for many to convince them of the insignificance of the revelation because of the comment from a person who claimed to have authority on twitter. Others chimed in to add that in fact there was a review of the copyright registration especially in high profile instances and these reviewers were satisfied with the evidence provided by Craig for the claim. At the moment Craig is being sued by Ira Kleiman for an amount of bitcoin that he believes he is entitled to because of Craig and Ira’s brother Dave working together on bitcoin. He is also engaged in suing a number of people from the cryptocurrency community for libel and defamation after they continued to use their social media/influencer positions to call him a fraud and a liar. He also has a number of patents lodged through his company nChain that are related to blockchain technologies. This has many people up in arms because in their mind Satoshi was part of a cypherpunk movement, wanted anonymity, endorsed what they believed to be an anti state and open source technologies and would use cryptography rather than court to prove his identity and would have no interest in patents.

If you listen to Craig with an open mind, what cannot be denied is the man is bloody smart. Whether he is honest or not is up to you to decide, but personally I try to give everyone the benefit of the doubt and then cut them off if i find them to be dishonest. What I haven’t really been able to do with my investigation of craig is cut him off. There have been many moments where I disagree with what he has had to say but I don’t think people having an opinion about something that I believe to be incorrect is the same as being a dishonest person. It’s very important to distinguish the two and if you are unable to do so there is a very real risk of you projecting expectations or ideals upon someone based off your ideas of who they are. Many times if someone is telling the truth but you don’t understand it, instead of acknowledging you don’t understand it, you label them as being stupid or dishonest. I think that has happened to an extreme extent with Craig. Let’s take for example the moment when someone in the slack channel asked Craig if he had had his IQ tested and what it was. Craig replied with 179. The vast majority of people on the internet have heard someone quote their IQ before in an argument or the IQ of others and to hear someone say such a score that is actually 6 standard deviations away from the mean score (so probably something like 1/100 000) immediately makes them reject it on the grounds of probability. Craig admits that he’s not the best with people and having worked with/taught many high functioning people (sometimes on the spectrum perhaps) on complex anatomical and physiological systems I have seen some that also share the same difficulties in relating to people and reconciling their genius and understandings with more average intelligences. Before rejecting his claim outright because we don’t understand much of what he says, it would be prudent to first check is there any evidence that may lend support to his claim of a one in a million intelligence quotient.

Craig has mentioned on a number of occasions that he holds a number of different degrees and certifications in relation to law, cryptography, statistics, mathematics, economics, theology, computer science, information technology/security. I guess that does sound like something someone with an extremely high intelligence could achieve. Now I haven’t validated all of them but from a simple check on Charles Sturt’s alumni portal using his birthday of 23rd of October 1970 we can see that he does in fact have 3 Masters and a PhD from Charles Sturt. Other pictures I have seen from his office at nChain have degrees in frames on the wall and a developer published a video titled Craig Wright is a Genius with 17 degrees where he went and validated at least 8 of them I believe. He is recently publishing his Doctorate of Theology through an on-chain social media page that you have to pay a little bit for access to sections of his thesis. It’s titled the gnarled roots of creation. He has also mentioned on a number of occasions his vast industry experience as both a security contractor and business owner. An archive from his LinkedIn can be seen below as well.

In fact here is an on chain collection of articles and videos relating to Craig called the library of craig - https://www.bitpaste.app/tx/94b361b205196560d1bd09e4e3b3ec7ad6bea478af204cabfe243efd8fc944dd


So there is a guy with 17 degrees, a self professed one in a hundred thousand IQ, who’s worked for Australian Federal Police, ASIO, NSA, NASA, ASX. He’s been in Royal Australian Air Force, operated a number of businesses in Australia, published half a dozen academic papers on networks, cryptography, security, taught machine learning and digital forensics at a number of universities and then another few hundred short articles on medium about his work in these various domains, has filed allegedly 700 patents on blockchain related technology that he is going to release on bitcoin sv, copyrighted the name so that he may prevent other competing protocols from using the brand name, that is telling you he is the guy that invented the technology that he has a whole host of other circumstantial evidence to support that, but people won’t believe that because they saw something that a talking head on twitter posted or that a Core Developer said, or a random document that appears online with a C S Wright signature on it that lists access to an address that is actually related to Roger Ver, that’s enough to write him off as a scam. Even then when he publishes a photo of the paper copy which appears to supersede the scanned one, people still don’t readjust their positions on the matter and resort back to “all he has to do is move the coins or sign a tx”.

Yes Craig was on the Cypherpunk mailing list back in the day, but that doesn’t mean that he was or is an anarchist. Or that he shares the same ideas that Code Is Law that many from the crypto community like to espouse. I myself have definitely been someone to parrot the phrase myself before reading lots of Craig’s articles and trying to understand where he is coming from. What I have come to learn from listening and reading the man, is that although I might be fed up with the systems we have in place, they still exist to perform important functions within society and because of that the tools we develop to serve us have to exist within that preexisting legal and social framework in order for them to have any chance at achieving global success in replacing fiat money with the first mathematically provably scarce commodity. He says he designed bitcoin to be an immutable data ledger where everyone is forced to be honest, and economically disincentivised to perform attacks within the network because of the logs kept in a Write Once Read Many (WORM) ledger with hierarchical cryptographic keys. In doing so you eliminate 99% of cyber crime, create transparent DAO type organisations that can be audited and fully compliant with legislature that’s developed by policy that comes from direct democratic voting software. Everyone who wants anonymous coins wants to have them so they can do dishonest things, illegal things, buy drugs, launder money, avoid taxes.

Now this triggers me a fair bit as someone who has bought drugs online, who probably hasn’t paid enough tax, who has done illegal things contemplating what it means to have that kind of an evidence ledger, and contemplate a reality where there are anonymous cryptocurrencies, where massive corporations continue to be able to avoid taxes, or where methamphetamine can be sold by the tonne, or where people can be bought and sold. This is the reality of creating technologies that can enable and empower criminals. I know some criminals and regard them as very good friends, but I know there are some criminals that I do not wish to know at all. I know there are people that do horrific things in the world and I know that something that makes it easier for them is having access to funds or the ability to move money around without being detected. I know arms, drugs and people are some of the biggest markets in the world, I know there is more than $50 trillion dollars siphoned in to off shore tax havens from the value generated as the product of human creativity in the economy and how much human charity is squandered through the NGO apparatus. I could go on and on about the crappy things happening in the world but I can also imagine them getting a lot worse with an anonymous cryptocurrency. Not to say that I don’t think there shouldn’t be an anonymous cryptocurrency. If someone makes one that works, they make one that works. Maybe they get to exist for a little while as a honeypot or if they can operate outside the law successfully longer, but bitcoin itself shouldn’t be one. There should be something a level playing field for honest people to interact with sound money. And if they operate within the law, then they will have more than adequate privacy, just they will leave immutable evidence for every transaction that can be used as evidence to build a case against you committing a crime.

His claim is that all the people that are protesting the loudest about him being Satoshi are all the people that are engaged in dishonest business or that have a vested interest in there not being one singular global ledger but rather a whole myriad of alternative currencies that can be pumped and dumped against one another, have all kinds of financial instruments applied to them like futures and then have these exchanges and custodial services not doing any Know Your Customer (KYC) or Anti Money Laundering (AML) processes. Bitcoin SV was delisted by a number of exchanges recently after Craig launched legal action at some twitter crypto influencetalking heads who had continued to call him a fraud and then didn’t back down when the CEO of one of the biggest crypto exchanges told him to drop the case or he would delist his coin. The trolls of twitter all chimed in in support of those who have now been served with papers for defamation and libel and Craig even put out a bitcoin reward for a DOX on one of the people who had been particularly abusive to him on twitter. A big european exchange then conducted a twitter poll to determine whether or not BSV should be delisted as either (yes, it’s toxic or no) and when a few hundred votes were in favour of delisting it (which can be bought for a couple of bucks/100 votes). Shortly after Craig was delisted, news began to break of a US dollar stable coin called USDT potentially not being fully solvent for it’s apparent 1:1 backing of the token to dollars in the bank. Binance suffered an alleged exchange hack with 7000 BTC “stolen” and the site suspending withdrawals and deposits for a week. Binance holds 800m USDT for their US dollar markets and immediately once the deposits and withdrawals were suspended there was a massive pump for BTC in the USDT markets as people sought to exit their potentially not 1:1 backed token for bitcoin. The CEO of this exchange has the business registered out of Malta, no physical premises, the CEO stays hotel room to hotel room around the world, has all kind of trading competitions and the binance launchpad, uses an unregistered security to collect fees ($450m during the bear market) from the trading of the hundreds of coins that it lists on its exchange and has no regard for AML and KYC laws. Craig said he himself was able to create 100 gmail accounts in a day and create binance accounts with each of those gmail accounts and from the same wallet, deposit and withdraw 1 bitcoin into each of those in one day ($8000 x 100) without facing any restrictions or triggering any alerts or such.
This post could ramble on for ever and ever exposing the complexities of the rabbit hole but I wanted to offer some perspective on what’s been happening in the space. What is being built on the bitcoin SV blockchain is something that I can only partially comprehend but even from my limited understanding of what it is to become, I can see that the entirety of the crypto community is extremely threatened as it renders all the various alt coins and alt coin exchanges obsolete. It makes criminals play by the rules, it removes any power from the developer groups and turns the blockchain and the miners in to economies of scale where the blockchain acts as a serverless database, the miners provide computational resources/storage/RAM and you interact with a virtual machine through a monitor and keyboard plugged in to an ethernet port. It will be like something that takes us from a type 0 to a type 1 civilisation. There are many that like to keep us in the quagmire of corruption and criminality as it lines their pockets. Much much more can be read about the Cartel in crypto in the archive below. Is it possible this cartel has the resources to mount such a successful psychological operation on the cryptocurrency community that they manage to convince everyone that Craig is the bad guy, when he’s the only one calling for regulation, the application of the law, the storage of immutable records onchain to comply with banking secrecy laws, for Global Sound Money?

https://archive.fo/lk1lH#selection-3671.46-3671.55

Please note, where possible, images were uploaded onto the bitcoin sv blockchain through bitstagram paying about 10c a pop. If I wished I could then use an application etch and archive this post to the chain to be immutably stored. If this publishing forum was on chain too it would mean that when I do the archive the images that are in the bitstragram links (but stored in the bitcoin blockchain/database already) could be referenced in the archive by their txid so that they don’t have to be stored again and thus bringing the cost of the archive down to only the html and css.

The Exhaustive EOS FAQ

The Exhaustive EOS FAQ

 
With the large number of new readers coming to this sub we need to make information easy to access so those readers can make informed decisions. We all know there is an unusually large amount of Fear, Uncertainty and Doubt (FUD) surrounding EOS. Frankly, when clear evidence is provided it’s not that difficult to see EOS for the extremely valuable project it is. This post hopes to begin to put an end to all the misinformation by doing the following:  
  • Giving a clear and concise answer to the most frequently asked questions in regards to EOS.
  • Giving a more in-depth answer for those who want to read more.
  • Allowing readers to make informed decisions by making credible information easy to access.
 
As EOS climbs the ranks we need to recognise there are going to be a lot of skeptical readers coming over and posting their questions. Sometimes they will be irrational, hostile and often just looking for a reaction. We should make it our responsibility to welcome everyone and refrain from responding emotionally to provocative posts, instead providing factual and rational answers.
I will add to this post as and when I can, if you have any ideas or spot any mistakes let me know and I'll get them fixed ASAP. Im planning to add a bit on the team, centralisation and DPOS, governance and EOS VC shortly but please let me hear your suggestions!
 

FAQ

1. How do you registeclaim your EOS tokens before June 2018?

 
Answer courtesy of endless. If you have not done so, you will need to create a new pair of EOS public and private keys and register them with an Ethereum address. This only needs to be done once.
On or around June 1, 2018 all EOS Tokens will become frozen and non-transferable on the Ethereum blockchain. Not long after, I suspect that EOS community members will create a snapshot of token balances that carry over onto a new community generated and selected EOS blockchain. block.one will not be launching EOS blockchains or operating any of their nodes. Additionally, this is a community subreddit unaffiliated in an official capacity with block.one

Did you buy your EOS tokens on an exchange? (Courtesy of IQOptionCoin)
REMEMBER YOU ONLY NEED TO REGISTER YOUR TOKENS IF YOU BOUGHT THEM ON AN EXCHANGE. YOU DON'T NEED TO CLAIM THEM.
  1. Go to the EOS website https://eos.io
  2. Scroll down and select "GET EOS"
  3. Tick all the required boxes and click "Continue"
  4. Scroll down and click "Register"
  5. Select Metamask, MyEtherWallet, or Ethereum Wallet
  6. Follow the guide.
  7. Remember that the reason you need to register your Ethereum ERC-20 address is to include your EOS tokens in order for the balance of your EOS Tokens to be included in the Snapshot if a Snapshot is created, you must register your Ethereum address with an EOS public key. The EOS snapshot will take place prior to the 1 June 2018. After this point your ERC-20 EOS tokens will be frozen. And you will be issued EOS tokens on the EOS blockchain.
So PLEASE REGISTER your Ethereum address NOW, don't forget about it, or plan on doing it some time in the near future.
There are a lot of submissions about this in /eos, so rather than making a new one please reply to this thread with any questions you may have. Don't forget to join the EOS mailing list: https://eos.io/#subscribe and join the EOS community on your platform(s) of choice: Telegram, Discord and/or Facebook.
And remember, if anyone instructs you to transfer ETH to an EOS contract address that doesn't match the address found on https://eos.io you are being scammed.

2. How will the token the ERC-20 EOS tokens be transferred to the native blockchain?

 

Quick answer:

There isn't one! Read the long answer then read it again, registering your Ethereum wallet is mandatory!
 

Long answer:

Within 23 hours after the end of the final period on June 1, 2018 at 22:59:59 UTC, all EOS Tokens will become fixed (ie. frozen) and will become non-transferrable on the Ethereum blockchain.
In order to ensure your tokens are transferred over to the native blockchain you must register your Ethereum address with an EOS public key, if you do not you will lose all your tokens! I am not going to link any tutorials as there are many that can be found by searching Google and YouTube.
block.one is helping with the development of snapshot software that can be used to capture the EOS token balance and registered EOS public key of wallets on the Ethereum blockchain. It is then down to the community to create the snapshot. This snapshot can be used when generating a genesis block for a blockchain implementing eos.io software. block.one will not be launching EOS blockchains or operating any of their nodes.
 
Exchange Support
Some exchanges have announced that they will support the token swap. Although using this method will undoubtedly be much simpler than registering the tokens yourself it also comes with its pitfalls.
  • It is highly likely there are going to be multiple networks running on the eos.io software that use the snapshot. It is highly unlikely that exchanges will support them all.
  • It is highly likely that exchanges will not support airdrops that use the snapshot.
Exchanges that have announced support for the token swap include:

3. What does EOS aim to achieve?

 

Quick answer:

EOS.IO software is aiming to provide a decentralized operating system which can support thousands of industrial scale DApps by enabling vertical and horizontal scaling.
 

Long answer:

EOS.IO is software that introduces a blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. This is achieved through an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across multiple CPU cores and/or clusters. The resulting technology is a blockchain architecture that has the potential to scale to millions of transactions per second, eliminates user fees and allows for quick and easy deployment of decentralized applications.

6. Which consensus mechanism does EOS use and what are Block Producers?

 

Quick answer:

Delegated Proof of Stake (DPOS) with Byzantine Fault Tolerance. Block Producers (BPs) produce the blocks of the blockchain and are elected by token holders that vote for them. BPs will earn block rewards for their service, these block rewards come in the form of EOS tokens produced by token inflation.
 

Long answer:

Taken from the EOS.IO Technical White Paper v2:
“EOS.IO software utilizes the only known decentralized consensus algorithm proven capable of meeting the performance requirements of applications on the blockchain, Delegated Proof of Stake (DPOS). Under this algorithm, those who hold tokens on a blockchain adopting the EOS.IO software may select block producers through a continuous approval voting system. Anyone may choose to participate in block production and will be given an opportunity to produce blocks, provided they can persuade token holders to vote for them.
The EOS.IO software enables blocks to be produced exactly every 0.5 second and exactly one producer is authorized to produce a block at any given point in time. If the block is not produced at the scheduled time, then the block for that time slot is skipped. When one or more blocks are skipped, there is a 0.5 or more second gap in the blockchain.
Using the EOS.IO software, blocks are produced in rounds of 126 (6 blocks each, times 21 producers). At the start of each round 21 unique block producers are chosen by preference of votes cast by token holders. The selected producers are scheduled in an order agreed upon by 15 or more producers.
Byzantine Fault Tolerance is added to traditional DPOS by allowing all producers to sign all blocks so long as no producer signs two blocks with the same timestamp or the same block height. Once 15 producers have signed a block the block is deemed irreversible. Any byzantine producer would have to generate cryptographic evidence of their treason by signing two blocks with the same timestamp or blockheight. Under this model a irreversible consensus should be reachable within 1 second."
 

7. How does the voting process work?

 
The voting process will begin once the Block Producer community releases a joint statement ensuring that it is safe to import private keys and vote.
Broadly speaking there will be two methods of voting:
  1. Command Line Interface (CLI) tools
  2. Web portals
EOS Canada has created eosc, a CLI tool that supports Block Producer voting. Other Block Producer candidates such as LibertyBlock are a releasing web portal that will be ready for main net launch. There will be many more options over the coming weeks, please make sure you are always using a service from a trusted entity.
Remember: Do not import your private key until you have seen a joint statement released from at least five Block Producers that you trust which states when it is safe to do so. Ignoring this warning could result in tokens lost.
 

8. What makes EOS a good investment?

 
  • Team - EOS is spearheaded by the visionary that brought us the hugely successful Bitshares and Steem - arguably with two projects already under his belt there is no one more accomplished in the space.
  • Funding - EOS is one of the best funded projects in the space. The block.one team has committed $1B to investing in funds that grow the EOS echo system. EOS VC funds are managed by venture leaders distributed around the world to insure founders in all markets have the ability to work directly with local investors. Incentives such as the EOS hackathon are also in place with $1,500,000 USD in Prizes Across 4 Events.
  • Community Focus - The team is aware that the a projects success depends almost entirely on its adoption. For this reason there has been a huge push to develop a strong world wide community. There is already a surplus number of block producers that have registered their interest and started to ready themselves for the launch and incentives the EOS hackathon are being used to grow the community. A index of projects using EOS can be found at https://eosindex.io/posts.
  • Technical Advantages - See point 9!
 

9. What are the unique selling points of EOS?

 
  • Scaleability
    • Potential to scale to millions of transactions per second
    • Inter-blockchain communication
    • Separates authentication from execution
  • Flexibility
    • Freeze and fix broken applications
    • Generalised role based permissions
    • Web Assembly
  • Usability
    • Elimination of transaction fees
    • True user accounts with usernames, passwords and account recovery (no more having to remember long cryptographic keys)
    • Web toolkit for interface development

EOS Whitepaper
 

10. Is there currently a working product?

 

Quick answer:

This depends entirely on your definition of working product. If a fully featured developer release meets your definition then yes!. Otherwise the public release will be June 2018.
 

Long answer:

EOS differs from other projects in that it aims to deliver a fully featured version of the software on launch. The Dawn 3.0 RC1 feature complete pre-release became available on April 5th. This version has all the features of the final release that is due June 2018. Further development will involve preparing the final system contract which implements all of the staking, voting, and governance mechanics. The common notion that there is no viewable code published is wrong and the initial Dawn 1.0 release has been available from September 14th 2017.
 
EOSIO V1 - June 2nd 2018
Dawn 3.0 RC1 - April 5th 2018
Dawn 3.0 Alpha - January 23rd 2018
Dawn 2.0 - December 4th 2017

11. EOS is an ERC-20 token, how can it possibly be a competitor to other platforms?

 

Quick answer:

The ERC-20 token is used only for raising funds during the token distribution; all tokens will be transferred to the native blockchain once launched.
 

Long answer:

EOS team has clearly stated their reason for choosing the Ethereum network when they described the rationale behind the ICO model. Specifically, the ICO should be a fair and auditable process, with as little trust required as possible. If you believe that an ICO should be fair, auditable, and trustless, you have no choice but to use a decentralized smart contract blockchain to run the ICO, the largest, and by-far most popular of which is Ethereum. Since EOS is intended to be a major competitor for Ethereum, some have seen this as a hypocritical choice. - Stolen from trogdor on Steam (I couldn’t word it any better myself).

12. Why do the eos.io T&C’s say the ERC-20 token has no value?

 
The EOS T&C’s famously state:
"The EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied, including, without limitation, any uses, purpose, attributes, functionalities or features on the EOS Platform."
 

Quick answer:

This is legal wording to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Most notably Tezos (links below).
 

Long answer:

This all comes down to legal issues. Anyone who’s been into crypto for 5 minuets knows that government bodies such as the Securities and Exchange Commission (SEC) are now paying attention to crypto in a big way. This legal wording is to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Many token creators that launched ICOs are now in deep water for selling unregistered securities.
 
A filing from the Tezos lawsuit:
"In sum, Defendants capitalized on the recent enthusiasm for blockchain technology and cryptocurrencies to raise funds through the ICO, illegally sold unqualified and unregistered securities, used a Swiss-based entity in an unsuccessful attempt to evade U.S. securities laws, and are now admittedly engaged in the conversion, selling, and possible dissipation of the proceeds that they collected from the Class through their unregistered offering."
 
To ensure EOS tokens are not classed as a unregistered security block.one has made it clear that they are creating the EOS software only and won’t launching a public blockchain themselves. This task is left down to the community, or more precisely, the Block Producers (BPs). The following disclaimer is seen after posts from block.one:
 
"block.one is a software company and is producing the EOS.IO software as free, open source software. This software may enable those who deploy it to launch a blockchain or decentralized applications with the features described above. block.one will not be launching a public blockchain based on the EOS.IO software. It will be the sole responsibility of third parties and the community and those who wish to become block producers to implement the features and/or provide the services described above as they see fit. block.one does not guarantee that anyone will implement such features or provide such services or that the EOS.IO software will be adopted and deployed in any way.”
 
It is expected that many blockchains using eos.io software will emerge. To ensure DAPPs are created on an ecosystem that aligns with the interests of block.one a $1bn fund will be has been created to incentivise projects to use this blockchain.

13. Why is the token distribution one year long?

 
Official statement from block.one:
“A lot of token distributions only allow a small amount of people to participate. The EOS Token distribution structure was created to provide a sufficient period of time for people to participate if they so choose, as well as give people the opportunity to see the development of the EOS.IO Software prior to making a decision to purchase EOS Tokens.”
 
It is also worth noting that block.one had no knowledge how much the the token distribution would raise as it is determined by the free market and the length of the token distribution is coded into the Ethereum smart contract, which cannot be changed.

EOS.io FAQ
 

14. Where is the money going from the token distribution?

 

Quick answer:

Funding for the project was raised before EOS was announced, the additional money raised from the token distribution is largely going to fund projects on EOS.
 

Long answer:

A large portion of the money raised is getting put back into the community to incentivise projects using eos.io software. block.one raised all the money they needed to develop the software before the ERC-20 tokens went on sale. There are some conspiracies that block.one are pumping the price of EOS using the funds raised. The good thing about blockchain is you can trace all the transactions, which show nothing of the sort. Not only this but the EOS team are going to have an independent audit after the funding is complete for piece of mind.
 
From eos.io FAQ:
“block.one intends to engage an independent third party auditor who will release an independent audit report providing further assurances that block.one has not purchased EOS Tokens during the EOS Token distribution period or traded EOS Tokens (including using proceeds from the EOS Token distribution for these purposes). This report will be made available to the public on the eos.io website.”

15. Who's using EOS?

 
With 2 months from launch left there is a vibrant community forming around EOS. Some of the most notable projects that EOS software will support are:
A more complete list of EOS projects can be found at eosindex.io.
 

16. Dan left his previous projects, will he leave EOS?

 

Quick answer:

When EOS has been created Dan will move onto creating projects for EOS with block.one.
 

Long answer:

When a blockchain project has gained momentum and a strong community has formed the project takes on a life of its own and the communities often have ideas that differ from the creators. As we have seen with the Bitcoin and Ethereum hark forks you cant pivot a community too much in a different direction, especially if its changing the fundamentals of the blockchain. Instead of acting like a tyrant Dan has let the communities do what they want and gone a different way. Both the Bitshares and Steem were left in a great position and with Dans help turned out to be two of the most successful blockchain projects to date. Some would argue the most successful projects that are actually useable and have a real use case.
What Dan does best is build the architecture and show whats possible. Anyone can then go on to do the upgrades. He is creating EOS to build his future projects upon it. He has stated he loves working at block.one with Brendan and the team and there is far too much momentum behind EOS for him to possibly leave.

17. Is EOS susceptible to DDoS attacks?

 
No one could have better knowledge on this subject than our Block Producer candidates, I have chosen to look to EOS New York for this answer:
"DDoS'ing a block producing is not as simple as knowing their IP address and hitting "go". We have distributed systems engineers in each of our candidate groups that have worked to defend DDoS systems in their careers. Infrastructure can be built in a way to minimize the exposure of the Block Producing node itself and to prevent a DDoS attack. We haven't published our full architecture yet but let's take a look at fellow candidate EOSphere to see what we mean. As for the launch of the network, we are assuming there will be attacks on the network as we launch. It is being built into the network launch plans. I will reach out to our engineers to get a more detailed answer for you. What also must be considered is that there will be 121 total producing and non-producing nodes on the network. To DDoS all 121 which are located all around the world with different security configurations at the exact same time would be a monumental achievement."

18. If block producers can alter code how do we know they will not do so maliciously?

 

Quick answer:

  • Block producers are voted in by stake holders.
  • Changes to the protocol, constitution or other updates are proposed to the community by block producers.
  • Changes takes 2 to 3 months due to the fact block producers must maintain 15/21 approval for a set amount of time while for changes to be processed.
  • To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation.
 

Long answer:

For this question we must understand the following.
  • Governance and why it is used.
  • The process of upgrading the protocol, constitution & other updates.
  • Dan’s view on open-entry systems built around anonymous participation.
 
Governance
Cryptography can only be used to prove logical consistency. It cannot be used to make subjective judgment calls, determine right or wrong, or even identify truth or falsehood (outside of consistency). We need humans to perform these tasks and therefore we need governance!
Governance is the process by which people in a community:
  1. Reach consensus on subjective matters of collective action that cannot be captured entirely by software algorithms;
  2. Carry out the decisions they reach; and
  3. Alter the governance rules themselves via Constitutional amendments.
Embedded into the EOS.IO software is the election of block producers. Before any change can be made to the blockchain these block producers must approve it. If the block producers refuse to make changes desired by the token holders then they can be voted out. If the block producers make changes without permission of the token holders then all other non-producing full-node validators (exchanges, etc) will reject the change.
 
Upgrade process
The EOS.IO software defines the following process by which the protocol, as defined by the canonical source code and its constitution, can be updated:
  1. Block producers propose a change to the constitution and obtains 15/21 approval.
  2. Block producers maintain 15/21 approval of the new constitution for 30 consecutive days.
  3. All users are required to indicate acceptance of the new constitution as a condition of future transactions being processed.
  4. Block producers adopt changes to the source code to reflect the change in the constitution and propose it to the blockchain using the hash of the new constitution.
  5. Block producers maintain 15/21 approval of the new code for 30 consecutive days.
  6. Changes to the code take effect 7 days later, giving all non-producing full nodes 1 week to upgrade after ratification of the source code.
  7. All nodes that do not upgrade to the new code shut down automatically.
By default, configuration of the EOS.IO software, the process of updating the blockchain to add new features takes 2 to 3 months, while updates to fix non-critical bugs that do not require changes to the constitution can take 1 to 2 months.
 
Open-entry systems built around anonymous participation
To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation.
Dan's quote:
"The only way to maintain the integrity of a community is for the community to have control over its own composition. This means that open-entry systems built around anonymous participation will have no means expelling bad actors and will eventually succumb to profit-driven corruption. You cannot use stake as a proxy for goodness whether that stake is held in a bond or a shareholder’s vote. Goodness is subjective and it is up to each community to define what values they hold as good and to actively expel people they hold has bad.
The community I want to participate in will expel the rent-seeking vote-buyers and reward those who use their elected broadcasting power for the benefit of all community members rather than special interest groups (such as vote-buyers). I have faith that such a community will be far more competitive in a market competition for mindshare than one that elects vote buyers."

19. What is the most secure way to generate EOS key pairs?

 
Block producer candidates EOS Cafe and EOS New York have come forward to help the community with this topic.
The block producer candidate eosnewyork has kindly posted a tutorial on steemit detailing the steps that need to be taken to generate key pairs using the official code on the EOS.IO Github.
The block producer candidate eoscafe has gone a step further and released an Offline EOS Key Generator application complete with GUI for Windows, Linux & Mac. Not only can this application generate key pairs but it can also validate key pairs and resolve public keys from private keys. This application has also been vouched for by EOS New York

LIVE Beijing Conference June 22, 2017: English Translation

Me and my partner are going to do English play by play here. Tickets were around 570 each, so if you found this helpful , please donate.
2:10 Checked in. Around 100 guests attending so far. Conference should officially start in 20 mins.
2:30 Conference started. Currently in the Microsoft Beijing Office Lobby. Just introductions so far. The video trailer they played before the conference was quite impressive and in English.
2:32 srikanth Raju is speaking in English. You guys are good for this part. Big point: Microsoft believes in a heterogeneous Blockchain environment for Azure. Mentioned​ Ethereum specifically coexisting with antshares.
2:41 Skipped Jiang Li, Microsoft senior consultant's section for some reason.
2:45 Feng han is talking about the rise of alipay and transactions becoming electronic. Believes that full automation is the next step. Alibaba is still only half automated in their logistics. Huawei is interested in building smart cities, and will need blockchain. Note: they aren't announcing a partnership. Just talking about it.
2:51 Feng han talking about current internet infrastructure not being safe for the futures smart infrastructure. Then talked about a class offered by a genius cryptography professor, wangxiaoyun at tsinghua. Made a joke about 300x returns since ICO.
2:57 Hongfei Da. Talking about bitcoin and history of crypto. Now talking about founding of Antshares. Discussing dBFT and consensus briefly. Now talking about ICO. State of AntShares: 432 nodes, 1058300 blocks, main env running for 150 days. 352 stars on GitHub. LOL talking about this subreddit specifically now. Coinmarketcap ranking.
All assets will be digitized. Two categories: 1. Proof of existence is on the blockchain. 2. Off chain physical assets like IDs, bikeshare locks, intellectual property.
Spirit of blockchain isn't decentralization. It is transparency and fairness via publicly agreed upon rules and data.
Mantra: digital asset + digital ID + smart contract = smart economy.
REBRANDING: NEO smart economy. Green logo
Neo contracts with C#, Java/kotlin, python, go
NeoX is like an interledger protocol
NeoQ is quantum safe encryption
NeoFS is a new database layer
Emphasized ecosystem partnership with bancor agrello matchpool
Missed some points because too fast. Will go back later.
3:28 innospace CEO talking. Selected AntShares to join a pool of 10 companies out of 800 applicants. Best companies get 100x growth. Talked about Neo contracts active dev community and emphasized fintrch fundamental paper.
3:35 Alex norta from agrello. English speaking. Introducing the agrello platform currently. Announced new white paper finished today and ICO occurring now.
3:43 Adam from Coindash. Marketing Coindash as a onestop crypto portfolio that enables social trading and facilitates ICOs. Gives test runs for ICOs and let's you gauge interest. Announcing foray into China with close partnership with NEST partnership.
3:59 they made a reference to the matrix where they all pushed buttons and the screen said, WAKE UP NEO
4:00 break for 30 mins
4:31 restarting. CTO of AntShares speaking. Explaining smart contracts. Telling a story about Coke vending machine software executing a smart contract, except it ate his money because of a malicious party blocking the coin entry. Blockchain is necessary to allow smart contracts to be executed fairly.
Neo is different from Eth and fabric because it has static contract calls, deterministic blockchain network calls, and uses oracle's instead of internet API calls. Example, different nodes will have different Google search results based off of IP location.
NeoVM vs EthVM vs Docker Dyanmic sharding for NeoVM makes parallel processing scale better than EVM which has static sharding. Variables in NeoVM are determined beforehand and then the sharding is done before computation as opposed to EVM which divides work inflexibly.
EVM has high coupling (bad). NVM has low coupling like docker. Execution of contracts depends too much on the nodes and blockchain. This point wasn't too clear. Coupling seems to be a concept that people don't talk about often. Sounds like he was saying that you need to run eth smart contracts on a test blockchain environment while NeoVM allows you to test and run code independent of blockchain.
Microsoft offers IDE plugins and compilers to help people develop on the Neo platform.
Digital certificate issuance and asset digitization are supported in Neo but not inherently in Eth.
Storage layer for contracts is built into Neo. You can give authorization for others to read or write your contract storage space. Also, if your contract has a bug, you can take the data and migrate it to a patched contract. Lastly, allows rental of storage space for contracts. No support for any of the three points above in EVM.
Giving example of locking an account for a period of time. Showing decentralized domains. Sounds a lot like Eth name service.
5:21 bijie tech CEO. Talking about Binance ICO. Introducing the Binance team. Binance is a coin to coin centralized exchange. Made a joke about not wanting to ICO but did it after seeing everyone elses valuations.
5:35 fangzhou charity entrepreneur. Became a multimillionaire after getting some ANS.
Money is freedom. Now wants to give charity loans to kids that need an operation but parents don't have the money. Because of new Chinese laws only 113 out of 500 NGOs can receive donation money. Therefore the market for charity is undersupplied by organizations that can use the money.
5:46 xiaobai medical founder
No fixed location, employees or resources. Wants to make a medical system where people record their illnesses and compare outcomes with other patients to determine what is the best treatment. Can also match patients with doctors. Sounds like a combo of ZocDoc and patientory.
5:55 nest smart fund founder
Problems of most funds are lack of liquidity, inability to participate in the invested company, and high management cost.
DAO on ethereum was hacked, but NEST wants to do what DAO does but more safely and more transparently. They choose C# ( made a joke about being at Microsoft and using C#).
Going to make a nest coin that is redeemable for some of the coins that the project backs.
.................................
Questions:
what's going to happen to ANS?
AntShares will retire and get redistributed as NEO in the new wallet software. You don't have to do anything. No reissue so investors don't get screwed. Exchanges will get contacted automatically.
How many devs do you have now?
2 full time devs. They are going to offer NEO bounties on code and hire more.
New exchange announcement?
Binance

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency

As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin.
Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin.
We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.

Community Terminology

Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin.
HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market.
TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down.
FUD: Fear. Uncertainty. Doubt.
FOMO: Fear of missing out.
Bull Run: Financial term used to describe a rising market.
Bear Run: Financial term used to describe a falling market.

What Is Bitcoin?

Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream.
Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.

A Brief History

Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began.
I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).

What Is Blockchain?

Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions.
The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain.
For more information regarding blockchain I’ve provided more resouces below:

What is Bitcoin Mining

Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info).
Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.

How do you Purchase Bitcoin?

The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin.
Popular exchanges include:
  • Coinbase
  • Kraken
  • Cex
  • Gemini
There’s tons of different exchanges. Just make sure you find one that supports your national currency.

Volatility

Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.

Transaction & Network Fees

Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward.
Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.

Security

In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.

Two-Factor Authentication (2FA)

Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.

SMS Authentication

The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.

Authenticator

The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator.
If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device.
Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).

Hardware Wallets

A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage).
Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor.
Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box.
I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.

Technical Aspects of Bitcoin

TL;DR
  • Address: What you send Bitcoin to.
  • Wallet: Where you store your Bitcoin
  • Max Supply: 21 million
  • Block Time: ~10 minutes
  • Block Size: 1-2 MB
  • Block Reward: BTC reward received from mining.

What is a Bitcoin Address?

A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.

What is a Bitcoin Wallet?

As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack).
My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion.
After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.

What is Bitcoins Max Supply?

The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).

What is Bitcoins Block Time?

The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of.
Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds.
For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.

What is Bitcoins Block Size?

There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB.
There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction.
Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB.
On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.

What is Block Reward?

Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.

Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain.
For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.

What is a Fork?

A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.

Soft Fork vs Hard Fork

The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain.
During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain.
Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain.
Examples of Bitcoin hard forks include:
  • Bitcoin Cash
  • Bitcoin Gold
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.

A Case For Bitcoin in a World of Centralization

Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.

Final Conclusions

Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally.
Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions.
Thanks for reading!

My Intern Experience

My Intern Experience
Shreemoon Rajbhandari
My Intern Experience
During my time as an undergraduate, one of the key experiences recommended is to do an internship. Gaining work experience as an intern overseas will improve a skill set in my area of interest. Working somewhere as culturally different and economically significant as China is a talking point in any interviews. There are many reasons that made me choose to do an internship in China. Definitively the best part of the experience has been living out of your comfort zone. Encountering new situations and experiences, that increase my self awareness, my capabilities and also to discover my weaknesses.
Over the past 2 years, we have seen many digital currencies/cryptocurrencies being introduced globally.These have added the aspect of using this financial ecosystem to eventually solve social issues. This could be the application of Blockchain technology in areas like logistics/supply chain to food security. Eventually, there would be many more areas where blockchain and related technology developers would be needed. It's emerging to change the way we solve the many roadblocks that we face.
Blockchain is considered to be one of the most trending topics. This is the right time for me to learn about the technology and start implementing. Blockchain is a notion that can be implemented directly or indirectly to any sector as such. Only two months prior, I had a minimal amount of knowledge about blockchain innovation, and my insight into blockchain comprised distinctly of an obscure comprehension of bitcoin and cryptographic money all in all.
During my internship, I was given investigation material to help assemble my base comprehension of Loopring and the blockchain innovation that it depends on. In the wake of beginning at Loopring, I have been given significantly more prominent chance to learn. While my comprehension of blockchain is still new, it has improved extensively since my first day at the organisation.
In this post, I would like to talk about two cryptographic methods aiming to give privacy to blockchain technology ; the zk-SNARKS and zk-STARKS protocols are two significant examples. We will look into their advantages and disadvantages, comparison between two protocols, and conclusion.
ZK-SNARKS vs ZK-STARKS
Along with the countless benefits of the Internet from which we can benefit, when we use it for social media or business company purposes, privacy is at greater risk. Approximately 90 million of Facebook users information were damaged by Cambridge Analytical data. The Wall Street stated that “ this is just the beginning, and the results are expected to grow”. The Equifax data breach revealed information on social media channels from private users. Thus, birth dates were exposed to the majority of the populations. Due to the Uber hack, data from over 55 million customers were also shared and exposed.
Privacy has consistently been seen as a valuable element within the cryptocurrency community. There is always a growing focus on improving privacy within the cryptocurrency space. Bitcoin, Ethereum, Litecoin and many other cryptocurrencies are all actively searching for the most convenient approaches to increase their security. It is the antecedent to fungibility, which is vital for a broadly used form of money. Additionally, most crypto-asset holders do not want their transaction history to be completely public to the world. Among the different cryptographic methods aiming to give privacy to blockchain technology; the zk-SNARK and zk-STARKS protocols are two main significant examples.
Two leading technologies today offer their cryptocurrencies - Monero and zcash— and strive to address protection issues. Monero uses the technology of Ring Confidential Signature. By contrast, Z-Cash uses zk-SNARK( Zero-Knowledge transparent knowledge argument), a technology that provides the ability to conduct anonymous transactions.
In recent years, zk-SNARKS has exploded as the most promising technology to solve blockchain privacy. It is a technology derived from proofs of zero-knowledge, a type of proof that anyone with a verification key can check this “proof” without disclosing the information itself. If the statement holds, a verifier will be convinced by a correct proof. If the statement is false, it is true that no prover can convince a verified statement.
zk-SNARK stands for :
- Zero-knowledge : if the statement is true, there is nothing the verifier learns beyond the fact that the statement is true.
- Succinct : The proof size needs to be small enough in a few milliseconds to be verified.
- Non-interactive :Only one set of information is sent to the verifier for verification, therefore there is no back and forth communication between the prover and verifier.
- Argument of Knowledge : A computationally soundproof: soundness runs counter to a prover leveraging polynomial-time, i.e. limited computing. Also, Without access to the witness (the private input needed to prove the statement), the evidence can not be constructed.
zk-SNARKS aims to provide fast, scalable solutions to ensure financial security. Therefore, transaction encryption is possible.When zk-SNARK is applied to a cryptocurrency, it implies you can conceal the majority of the transaction data information. This incorporates the sender address, collector address, just as the transaction sum amount. zk-SNARKS enables us to shroud the majority of this data information, while likewise enabling the system to affirm and verify the transactions. It amplifies security while maintaining consensus. In the realm of blockchain, it is one of the most exceptional blockchain level protection innovation being used.
With the launch of version 3.0, Loopring’s decentralised protocol solution struck a noteworthy milestone in early May- adding off-chain scaling and fee optimisation using zk-SNARKs. Low fees, liquidity, transparency and security are the key goal of the loopring solution. Loopring says the new Loopring 3.0 based zk-SNARK will increase trade speeds and on-chain activity efficiency tenfold. The data previously stored on-chain in Loopring 3.0 is now stored off-chain in a Merkle tree and then used as required in zk-SNARKS, updating the tree.
Be that as it may, there are a few issues with zk-SNARKS. The main problem has been the need for a trusted setup. zk-SNARKS rely on a permission private key. This essentially undermines the entire purpose of decentralised public blockchain. By introducing the need to trust a person rather than code, you threaten the entire concept of trustlessness. In theory, a prover with sufficient computational power could create fake proofs, and this is one of the reasons why many consider quantum computers as a threat to zk-SNARKs (and blockchain systems).
Last year zk-SNARKS were incorporated on a MIT Tech Review list of the top 10 Breakthrough Technologies of 2018 among AI advancements. zk-SNARKS allows both a tremendous speedup in verifying the correctness of a computation while at the same time it hides the private details from prying eyes. Some of the potential uses citied in MIT article were verifying you’re over 18 without having to share your date of birth, and providing you have a enough money in your back account as collateral without having to give away account details like your exact balance. It establishes trust which you need to interact on the blockchain. Zk-SNARK proofs are as of now being used on Zcash, on JP Morgan Pursue's blockchain-based payment system, and as an approach to safely validate customers to servers.
The more developed version of zk-SNARKS is called zk-STARKS which stands for :
Zero-Knowledge
Scalable
Transparent
Argument of Knowledge
zk-STARKS verifications are currently being touted as the better than ever form of the convention, tending to a considerable lot of the past disadvantages of zk-SNARKs. It has demonstrated an approach to accomplish a similar degree of privacy as zk-SNARKS without the requirement for the trusted setup. Starks are practically superior to Snarks as they require weaker crypto suppositions, they don't require a trusted setup and are post-quantum resistant. zk-SNARKs are based on Elliptic-Curve Cryptography, which is susceptible to advances in Quantum-Computers. zk-STARKs, on the other hand are Post-Quantum system meaning that even if Quantum-computers become powerful and ubiquitous they will not have an advantage, compared to classical computers, in breaking zk-STARKs. Anyway they have a noteworthy downside, as in the proof being too enormous. Their problem is their storage requirements. STARKs are doubly scalable, which means the proof verification is exponentially faster than the original computation’s time but the drawback is the size of the proof they create being too large, possibly 2 or 3 orders of magnitude more than those produced by zk-SNARKs. One example : StarkWare solves the inherent problems of scalability and privacy of blockchains. Using STARK technology, they generate a full proof-stack to produce and verify computer integrity tests. They utilise STARKs to batch transactions into a single proof that is verified on Ethereum. Matt Taylor states that the present iteration of StarkDEX demonstrates the viability of using STARKs for the scalability of Layer-2 by showing a substantial rise in the amount of blockchain transaction.
The idea of zk-STARKS was proposed by Eli-Ben Sasson, a professor at the Technion-Israel institute of Technology. zk-STARKS provide proofs that can be verified a lot quicker than zk-SNARKS. At the present time, Z-cash and Ethereum are on the whole considering to utilize zk-STARKS. zk-STARKS have solved the trusted setup issue. They have totally expel the requirement for multiple parties to create the private key required for the string. Rather everything needed to produce the proofs is public and the verifications are generated from arbitrary numbers. zk-STARKS actually removed the necessity in zk-SNARKS for unbalanced cryptography and rather utilizes the hash fuctions like those found in Bitcoin mining. In addition, they ought to have longer timeframe of realistic usability as far as their crytographic resilience than zk-SNARKS. However, there are some impediment of zk-STARKS, the main issue with zk-STARKS is their size. The verifications it uses are basically too enormous to use in many blockchains as they stand. As indicated by Vitalik Buterin, zk-STARKS will result in proofs of a couple of hundreds kilobytes versus the 288 bytes seen in zk-SNARKS.

The Difference Between zk-STARKS and zk-SNARKS.

The complexity of communication : With the computation’s expanded complexity, the zk-SNARKS communication complexity also increases linearly, whereas zk-STARKs develops in the opposite direction and grows slowly as the computation size grows.The graph above shows that the communication required by the zk-STARKs to complete the calculation rises much slower than zk-snarks as the underlying evidence increases in complexity.

Source : The Medium - Coinmonks
The complexity of the verifier : zk-STARKs slightly widening with the development in computation size. On the other side, for confirmation evidence, zk-SNARKs requires less time than zk-STARKs. zk-STARKs, for instance need up to 100 ms to verify and zk-SNARKs need only up to 10ms. The graph above illustrates the the time taken by the zk-STARK to verify an evidence rises very slowly compared to the zk-SNARK as the underlying evidence increases in complexity.

Overall these two protocols have excellent potential in the cryptocurrency globe and can be a breakthrough avenue for mainstream implementation. Both conventions are truly needed steps to protect our privacy.

All About Zcoin

All About Zcoin

https://preview.redd.it/hixbz9f3lxm31.jpg?width=1200&format=pjpg&auto=webp&s=43896de84a3693d840c84057c0314af71718f0a3
What is Zcoin?
Zcoin, also referred to as XZC or Zerocoin, is an open source decentralized cryptocurrency that provides privacy and anonymity for its users when making transactions.
To achieve its privacy and anonymity, Zcoin uses zero-knowledge proofs via the Zerocoin protocol, which is at this moment in time one of the most cited cryptography papers.
According to Wikipedia, in cryptography, a zero-knowledge proof or zero-knowledge protocol is a method in which one party proves to another party (the verifier) that a given statement is actually true.
In other words, in a transaction with Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default, leaving you vulnerable. All it takes is one link to your personal information or IP to find out the origin of the coins.
However, when you trade with Zcoin’s Zercoin feature, your transaction history is not linked to the actual coins. Only the receiver and sender know that the funds have actually been exchanged.

How Does Zcoin Work?

Zcoin works on the Zerocoin protocol by enforcing Zero-knowledge proofs. Here are the components of Zcoin to explain how it works.
Mint: When sending a private transaction with Zcoin, all you need to do is select the number of coins you want to mint. Post that your normal Zcoin balance would reduce automatically and you will be credited with new coins and no transaction history. In essence, your old coins are burned cryptographically, which prevents anyone else from using them again and being directed to your transaction history. You get credited with new coins with no history, while the total supply is maintained.
For now, you can only mint in denominations of 1, 10, 25, 50 and 100. If you choose ‘100’ coins to be minted, for instance, you will instantly be credited with 100 new Zcoins with no history attached to them.
  • Spend: When you want to make a private transaction, you will be required to use these ‘100’ newly minted coins. From this pool of funds, you can now send any amount in any denomination to anyone anonymously because no history is attached to it.
  • Repeat: You can ‘mint’ and ‘send’ Zcoins any number of times at anytime with your privacy intact.

Zcoin’s Vision

Zcoin seeks to improve things that Bitcoin hasn’t been able to so far, some of which include fungibility, privacy and miner’s centralization.
Users of Zcoin can enjoy full fungibility and privacy along with demolishing miner’s centralization by implementing a better proof of work algorithm called MTP.
Total Zcoin supply
Only 21 million units of Zcoin will ever be produced. Currently, there are about 3.4 million units in circulation, with the rest yet to be mined.
But the total supply has increased by 388450 XZC units after a Zcoin code bug, which the team refused to roll back due to economic reasons, which is why the total supply stands at approximately 21.4 million.
Every 10 minutes, a Zcoin block is mined and 50 coins are generated, making 72,000 Zcoins per day.
Market cap of Zcoin
According to CoinMarketCap, the total circulating supply of Zcoin is 5,757,841 XZC and the current unit price is $9.6. That makes the market cap approximately $55 million*.*

Zcash:
Zcash is a decentralized and open-source peer-to-peer cryptocurrency that provides strong privacy protections. It was created as a fork of Bitcoin and, like bitcoin, it also has a hard limit of 21 million coins. Unlike bitcoin, however, Zcash offers total privacy for its users maintaining the absolute anonymity behind each transaction along with the parties and the amounts involved in it.
PIVX:
PIVX, which stands for Private Instant Verified Transaction, is an open-source, decentralized form of digital online money that uses blockchain technology. This makes it easy to transfer all around the world in an instant with low transaction fees with market leading security & privacy. PIVX focuses on privacy, security, anonymity, and instant transactions.
Monero:
Monero is a fast, private, secure and untraceable digital currency system that uses a special kind of cryptography to keep all its transactions 100% unlinkable and untraceable. With Monero, you are your own bank. You can spend safely, knowing that others cannot see your balances or track your activity.
Some Zcoin misconceptions
There are some misconceptions regarding Zcoin:
  • Some believe that, since Zcoin has a trusted setup that allows indefinite minting of coins, it is not safe. This is untrue. Of course, to start with they had to use a trusted setup because they have an auditable total coin supply that prevents any form of cheating. This downside however, is being taken care of by removing this trusted setup in the near future and when that happens, Zcoin will be one of the serious coins to count on for privacy.
  • Zcoin has been considered as Zcash’s fork but that is also not true because Zcash is based on the Zerocash protocol whereas Zcoin was started from scratch by applying Zerocoin tech.
Now that some of the Zcoin’s misconceptions have been cleared, here’s a look into its future.

Zcoin’s Future & Roadmap

Zcoin’s future is quite promising and worth watching based on these interesting milestones on their roadmap:
  • Zcoin is the first coin to implement MTP proof of work, which makes it possible for general masses to mine Zcoin with GPUs and CPUs. MTP doesn’t allow costly ASIC-like miners to mine XZC coins.
  • Zcoin is also implementing Znodes to make their cryptocurrency more decentralized and anonymous. These Znodes will be like masternodes and facilitate anonymous transactions as making an anonymous transaction single-handedly is quite computational.
  • Znodes will be incentivized by reducing some portion of the founder’s reward. Also, the surplus funds that get generated from the founder’s reward reduction would be used for hiring new developers and increased marketing efforts.
  • Another agenda on their roadmap is to bring inbuilt Tor or some IP obfuscation mechanism that will make it completely anonymous.
  • Apart from these, some innovative and exciting things like sigma protocol, decentralized anonymous voting and Zcoin Labs are on their roadmap, making this project worth checking out.
  • Last but not least, its recent price is a good indicator of its healthy market sentiment and shows that there are people who understand this project’s worth. Just to put things into perspective – a unit of Zcoin was priced $2 in March 2017 and now it is $37*.*

Zcoin Team & Progress

Zerocoin is a cryptocurrency proposed by professor Matthew D. Green, a professor of Johns Hopkins University, and graduate students Ian Miers and Christina Garman. It was proposed as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions.
Zerocoin was first implemented into a fully functional cryptocurrency and released to the public by Poramin Insom, the lead developer, as Zcoin in September 2016.
Some of the notable dev members of the team are listed below.
Poramin Insom
Founder and Core Developer
Poramin Insom created what was the world's 4th most valuable cryptocurrency in February 2014. He is also the world's first person to implement stealth addresses in QT-Wallets, improving cryptocurrency anonymity. He earned a master’s degree in Information Security from Johns Hopkins University, where he wrote a paper on a proposed practical implementation of the Zerocoin protocol.
Alexander N.
Developer
Alexander N. aka Aizensou is a full-stack developer who has experience in many programming languages (C++, C#, Python, Perl, Java etc.) and has been involved in the cryptocurrency space since 2013. He has a broad development portfolio from low level APIs in Python and C++ to Android native applications in Java. In addition to his involvement in cryptocurrencies, Alexander was doing his P.h.D. in machine learning at a German university from 2012 to 2016.
Saran Siriphantnon
Developer
Saran Siriphantnon is the CTO of Satang.co/Satoshift, a fintech company focusing on creating an open financial system for Southeast Asia. He served as President of the Computer System Administrator Group at King Mongkut's Institute of Technology Ladkrabang.
Tadhg Riordan
Solidity Developer
Tadhg Riordan is a 24 year old Software Developer from Wexford, Ireland. He recently completed his MSc from Trinity College Dublin, where he worked with Blockchain privacy mechanisms, focusing particularly on Zero-Knowledge Proofs and the Ethereum platform. He is a strong advocate for the adoption of cryptocurrency and for complete financial privacy.
Apart from these, their team comprises of other developers, community managers, support personnel and advisors who maintain the required balance.

Advisors:

Aram Jivanyan (Cryptography Advisor): Co-Founder at Skycryptor & KMSchai
Torphop Korgtadam (It Security Consultant): Senior Vice President, Head Of Internal Audit Strategy, Innovation and Decision Science at United Overseas Bank Limited
Alexander N. aka Aizensou (Advisor)

Unique/Key Features Against Its Competitors:

  • Anonymous transactions. The project establishes a notably higher level of anonymity and seeks to bypass current analysis techniques which governments use to reveal the identity of users.
  • Not subject to transaction graph analysis. Zcoin has an anonymity set that encompasses all minted coins in a particular RSA accumulator that can scale to many thousands.
  • Innovative process. Tokens are burned cryptographically and replaced with new coins without a transaction history. This actively prevents anyone else from using the tokens again and stops the public from being directed to a user's transaction history.
  • Transparency focused. Zcoin's main advantage is its auditable money supply.
