Blockchain, the amazing solution for almost nothing
Article from Jesse Frederik at the Correspondent Highlights: At its core, blockchain is a glorified spreadsheet (think: Excel with one table). In other words, a new way to store data. In traditional databases there’s usually one person who’s in charge, who decides who can access and input data, who can edit and remove it. That’s different in a blockchain. Nobody’s in charge, and you can’t change or delete anything, only view and input data. Nakamoto thought that everyone would be able to work equally hard to solve the puzzles. But some companies have exclusive access to specialised hardware, cheap electricity and space, which makes them much better able to fulfil this role. What was envisioned as decentralised has become centralised again, because of the advantages of scale. Out of over 86,000 blockchain projects that had been launched, 92% had been abandoned by the end of 2017, according to consultancy firm Deloitte. Firstly: the technology is at loggerheads with European privacy legislation, specifically the right to be forgotten. Once something is in the blockchain, it cannot be removed. For instance, hundreds of links to child abuse material and revenge porn were placed in the bitcoin blockchain by malicious users. It’s impossible to remove those. The presumed hackers of Hillary Clinton’s email were caught, for instance, because their identity could be linked to bitcoin transactions. A number of researchers from Qatar University were able to ascertain the identities of tens of thousands of bitcoin users fairly easily through social networking sites. Other researchers showed how you can de-anonymise many more people through trackers on shopping websites. The fact that no one is in charge and nothing can be modified also means that mistakes cannot be corrected. A bank can reverse a payment request. This is impossible for bitcoin and other cryptocurrencies. So anything that has been stolen will stay stolen. There is a continuous stream of hackers targeting bitcoin exchanges and users, and fraudsters launching investment vehicles that are in fact pyramid schemes. According to estimates, nearly 15% of all bitcoin has been stolen at some point. Solving all those complex puzzles requires a huge amount of energy. So much energy that the two biggest blockchains in the world – bitcoin and Ethereum – are now using up the same amount of electricity as the whole of Austria. Carrying out a payment with Visa requires about 0.002 kilowatt-hours; the same payment with bitcoin uses up 906 kilowatt-hours, more than half a million times as much, and enough to power a two-person household for about three months. OK, so with bitcoin, banks can’t just remove money from your account at their own discretion. But does this really happen? I have never heard of a bank simply taking money from someone’s account. If a bank did something like that, they would be hauled into court in no time and lose their license. Technically it’s possible; legally, it’s a death sentence. Of course scammers are active everywhere. People lie and cheat. But the biggest problem is scams by data suppliers. (for instance: someone secretly registers a hunk of horse meat as beef), not by data administrators (for instance: a bank makes money disappear). A blockchain is a database – it’s not a self-regulating system that checks all data for correctness, let alone one that calls a halt to unauthorised building works. The same rules apply for blockchain as for any database: if people put garbage into it, what comes out is also garbage. Or as Bloomberg columnist Matt Levine wrote: “My immutable unforgeable cryptographically secure blockchain record proving that I have 10,000 pounds of aluminium in a warehouse is not much use to a bank if I then smuggle the aluminium out of the warehouse through the back door.” Data should reflect reality, but sometimes reality changes and the data stays the same. That’s why we have notaries, supervisors, lawyers – actually, all those boring people that blockchain thinks it can do without. But wasn’t that the whole point of blockchain, that you could do without these trusted third parties? So what are they doing here? If you ask me, they’re building a completely normal, run-of-the-mill database, but extremely inefficiently. Once you’ve cut through all the jargon, the report turns out to be a boring account of database architecture. They write about a distributed ledger (that’s a shared database), about smart contracts (that’s an algorithm) and about proof of authority (that’s the right to veto whatever is entered in the database). “I work with code, so people see me as a magician,” he said proudly. It was always rather surprising to him – a magician? He spends half his time yelling at his screen in frustration, while he programmes strips of duct tape to repair creaky PHP script from years and years ago. What Tim meant was that ICT is like the rest of the world – a big old mess. And that’s something that we – outsiders, laypeople, non-tech geeks – simply refuse to accept. Councillors and managers think that problems – however large and fundamental they are – evaporate instantaneously thanks to technology they’ve heard about in a fancy PowerPoint presentation. How will it work? Who cares! Don’t try to understand it, just reap the benefits! According to a recent survey carried out by consultancy firm Deloitte, 70% of business executives said they had a lot of expertise in the field of blockchain. The greatest advantage of blockchain, according to them, is its speed. That's a bit stupid, because even fanatics see speed as a problem, not a feature. This is the market for magic, and that market is big. Whether it’s about blockchain, big data, cloud computing, AI or other buzzwords.
Nendly, the Notion-Friendly Forum is a social media site that offers a novel approach to Internet communities.
Social media today is a poor avenue for Internet conversations. Everyone can have their say, but only in their particular echochamber. While I've written more about it in an essay, go to cc and you'll see the main crux. The things you can talk about here won't fly so well there. Now why is that? It's because on Reddit, we have a downvote button. And since what you see is based on vote scores, it's essentially a censorship button. If you don't hold a 51% opinion, those in the majority will vote you down, and you'll leave to join another where the electorate is more favorable. And so we get a million insulated communities, each so sure that the others are wrong and needlessly hostile. But it doesn't have to be this way! Nendly uses a state-of-the-art voting algorithm that enables discussions wherein many competing ideas are possible. Instead of the upvote and downvote buttons being directly tied to what users see, Nendly performs viewpoint analysis to find the best content among a range of diverse beliefs. And since it uses game-theory, there's no possibility for an cc style take-over. You can read more about it here, but basically I've solved the cc problem, as seen in Nendly's much friendlier n/crypto community. Now there's a lot more to the site, including huge usability improvements and features Reddit doesn't have, but I'll have to leave it for a video I'll put out tomorrow. Ask me any questions and I'll address them then. (I need to sleep, it's been a wild day).
Ok but why is this a big deal for nano? The benefits are many.
Nano is exclusively integrated site-wide. Instead of Reddit "awards", we have nano-based gifts that mostly go to the end user. That's right, you can get paid to use social media. Forget Reddit's ETH integration, we've beet 'em to it, guys!
When someone awards your post or comment with nano, you get a helpful message from the system user, who gives you information about nano, the foundation, wallets, etc. so you can adopt it yourself.
The user base will be primarily non-crypto people, since I've intentionally built the site for a general-purpose audience. And since nano is the only crypto fully-integrated, we'll be actively getting people to join Nano. They won't just see it on a list with 50 other coins and bitcoin at the top. We are talking REAL ADOPTION.
With scale comes power. Imagine if we had complete control over the code for this subreddit. If someone had an idea requiring scale, we could actually fulfill it. We wouldn't have the "okay but where will you get your users" problem. If someone had an idea like ads that pay you nano to view them, we'd be able to break down that barrier. Well here's the thing, we've got Nendly, and with it we can solve the scale problem once and for all. Not just with n/crypto, but with the entire site if we like. As Nendly grows, so too does our launchpad.
There's more too for nano I'll put in the video. Again, ask me questions and I'll answer them when I'm not so tired :)
There's a lot of features that I'll be releasing over the coming days and weeks that are close to being done. For now, so I could meet the August deadline I set for myself, it's a Desktop-only experience with mobile coming very soon (we've also got a public API that's mostly done, PM me if you want to build an App or something). So hey, try my site out! You'll find updates coming out very fast since most of the cool stuff is ~90% done. I plan on a major update happening once a week, so it'll be a quick-moving experience if you join our community. Please bare with me since it's just now public. There's bound to be funny bugs we'll run into, and I already know some email providers are dropping my mail since they've never heard of nendly.com. And who knows, maybe the servers will explode. Also, I want to say thanks for all the support these past 2 months. I really wanted to give you something you could use before August ended, and thankfully we made it just hours before September! Edit ok, here’s the video!
Stakenet (XSN) - A DEX with interchain capabilities (BTC-ETH), Huge Potential [Full Writeup]
Preface Full disclosure here; I am heavily invested in this. I have picked up some real gems from here and was only in the position to buy so much of this because of you guys so I thought it was time to give back. I only invest in Utility Coins. These are coins that actually DO something, and provide new/build upon the crypto infrastructure to work towards the end goal that Bitcoin itself set out to achieve(financial independence from the fiat banking system). This way, I avoid 99% of the scams in crypto that are functionless vapourware, and if you only invest in things that have strong fundamentals in the long term you are much more likely to make money. Introduction
Stakenet is a Lightning Network-ready open-source platform for decentralized applications with its native cryptocurrency – XSN. It is powered by a Proof of Stake blockchain with trustless cold staking and Masternodes. Its use case is to provide a highly secure cross-chain infrastructure for these decentralized applications, where individuals can easily operate with any blockchain simply by using Stakenet and its native currency XSN.
Ok... but what does it actually do and solve? The moonshot here is the DEX (Decentralised Exchange) that they are building. This is a lightning-network DEX with interchain capabilities. That means you could trade BTC directly for ETH; securely, instantly, cheaply and privately. Right now, most crypto is traded to and from Centralised Exchanges like Binance. To buy and sell on these exchanges, you have to send your crypto wallets on that exchange. That means the exchanges have your private keys, and they have control over your funds. When you use a centralised exchange, you are no longer in control of your assets, and depend on the trustworthiness of middlemen. We have in the past of course seen infamous exit scams by centralised exchanges like Mt. Gox. The alternative? Decentralised Exchanges. DEX's have no central authority and most importantly, your private keys(your crypto) never leavesYOUR possession and are never in anyone else's possession. So you can trade peer-to-peer without any of the drawbacks of Centralised Exchanges. The problem is that this technology has not been perfected yet, and the DEX's that we have available to us now are not providing cheap, private, quick trading on a decentralised medium because of their technological inadequacies. Take Uniswap for example. This DEX accounts for over 60% of all DEX volume and facilitates trading of ERC-20 tokens, over the Ethereum blockchain. The problem? Because of the huge amount of transaction that are occurring over the Ethereum network, this has lead to congestion(too many transaction for the network to handle at one time) so the fees have increased dramatically. Another big problem? It's only for Ethereum. You cant for example, Buy LINK with BTC. You must use ETH. The solution? Layer 2 protocols. These are layers built ON TOP of existing blockchains, that are designed to solve the transaction and scaling difficulties that crypto as a whole is facing today(and ultimately stopping mass adoption) The developers at Stakenet have seen the big picture, and have decided to implement the lightning network(a layer 2 protocol) into its DEX from the ground up. This will facilitate the functionalities of a DEX without any of the drawbacks of the CEX's and the DEX's we have today. Heres someone much more qualified than me, Andreas Antonopoulos, to explain this https://streamable.com/kzpimj 'Once we have efficient, well designed DEX's on layer 2, there wont even be any DEX's on layer 1' Progress The Stakenet team were the first to envision this grand solution and have been working on it since its conception in June 2019. They have been making steady progress ever since and right now, the DEX is in an open beta stage where rigorous testing is constant by themselves and the public. For a project of this scale, stress testing is paramount. If the product were to launch with any bugs/errors that would result in the loss of a users funds, this would obviously be very damaging to Stakenet's reputation. So I believe that the developers conservative approach is wise. As of now the only pairs tradeable on the DEX are XSN/BTC and LTC/BTC. The DEX has only just launched as a public beta and is not in its full public release stage yet. As development moves forward more lightning network and atomic swap compatible coins will be added to the DEX, and of course, the team are hard at work on Raiden Integration - this will allow ETH and tokens on the Ethereum blockchain to be traded on the DEX between separate blockchains(instantly, cheaply, privately) This is where Stakenet enters top 50 territory on CMC if successful and is the true value here. Raiden Integration is well underway is being tested in a closed public group on Linux. The full public DEX with Raiden Integration is expected to release by the end of the year. Given the state of development so far and the rate of progress, this seems realistic. Tokenomics 2.6 Metrics overview (from whitepaper)
Ticker: XSN. Currency type: Coin.
Consensus: Minting Proof of Stake, Trustless Proof of Stake.
XSN is slightly inflationary, much like ETH as this is necessary for the economy to be adopted and work in the long term. There is however a deflationary mechanism in place - all trading fees on the DEX get converted to XSN and 10% of these fees are burned. This puts constant buying pressure on XSN and acts as a deflationary mechanism. XSN has inherent value because it makes up the infrastructure that the DEX will run off and as such Masternode operators and Stakers will see the fee's from the DEX. Conclusion We can clearly see that a layer 2 DEX is the future of crypto currency trading. It will facilitate secure, cheap, instant and private trading across all coins with lightning capabilities, thus solving the scaling and transaction issues that are holding back crypto today. I dont need to tell you the implications of this, and what it means for crypto as a whole. If Stakenet can launch a layer 2 DEX with Raiden Integration, It will become the primary DEX in terms of volume. Stakenet DEX will most likely be the first layer 2 DEX(first mover advantage) and its blockchain is the infrastructure that will host this DEX and subsequently receive it's trading fee's. It is not difficult to envision a time in the next year when Stakenet DEX is functional and hosting hundreds of millions of dollars worth of trading every single day. At $30 million market cap, I cant see any other potential investment right now with this much potential upside. This post has merely served as in introduction and a heads up for this project, there is MUCH more to cover like vortex liquidity, masternodes, TOR integration... for now, here is some additional reading.

A minimum amount of resources is obviously required to prevent easy attacks, but we are making sure that being active part of the IOTA network can be possible without crazy investments. we are building our solution in such a way that the protocol is fair and lightweight. 📷 Hans Moog [IF]어제 오후 11:24 IOTA is not "free to use" but it's - fee-less you have tokens? you can send them around for free 📷 Hans Moog [IF]어제 오후 11:25 you have no tokens? you have to pay to use the network 📷 lekanovic어제 오후 11:25 I think it is a smart way to avoid the spamming network problem 📷 Hans Moog [IF]어제 오후 11:26 owning tokens is essentially like owning a share of the actual network and the throughput it can process 📷 Hans Moog [IF]어제 오후 11:26**** if you don't need all of that yourself, you can rent it out to people and earn money 📷 Hans Moog [IF]어제 오후 11:27 mana = tokens * time since you own them simplified 📷 Hans Moog [IF]어제 오후 11:27 the longer you hold your tokens and the more you have, the more mana you have but every now and then you have to move them to "realize" that mana 📷 lekanovic어제 오후 11:28 Is there any other project that is using a Mana solution to the network fee problem ? 📷 Hans Moog [IF]어제 오후 11:28 nah the problem with current protocol is that they are leader based 📷 Hans Moog [IF]어제 오후 11:29 you need absolute consensus on who the current leaders are and what their influence in the network is that's how blockchains works 📷 Hans Moog [IF]어제 오후 11:29 if two block producers produce 2 blocks at the same time, then you have to choose which one wins and where everybody attaches their next block to IOTA works differently and doesn't need to choose a single leader we therefore have a much bigger flexibility of designing our sybil protection mechanisms in a way, mana is also supposed to solve the problem of "rewarding" the infrastructure instead of the validators in blockchain only the miners get all the money running a node and even if it's one that is used by a lot of people will only cost you won't get anything back no fees, nothing the miners get it all 📷 Hans Moog [IF]어제 오후 11:31 in IOTA, the node operators receive the mana which gives them a share of the network throughput 📷 Hans Moog [IF]어제 오후 11:32 because in blockchain you need to decide whose txs become part of the blocks and it's not really based on networking protocols like AIMD 📷 lekanovic어제 오후 11:33 And the more Mana your node have, the more trust your node has and you have more to say in the FPC, is that correct? 📷 Hans Moog [IF]어제 오후 11:33 yeah a node that has processed a lot of txs of its users will have more mana than other nodes and therefore a bigger say in deciding conflicts its a direct measure of "trust" by its users 📷 lekanovic어제 오후 11:34 And choosing committee for dRNG would be done on L1 protocol level? Everything regarding Mana will be L1 level, right? 📷 Hans Moog [IF]어제 오후 11:35 Yeah Mana is layer1, but will also be used as weight in L2 solutions like smart contracts 📷 lekanovic어제 오후 11:35 And you are not dependant on using SC to implement this 📷 Hans Moog [IF]어제 오후 11:35 No, you don't need smart contracts That's all the base layer 📷 Hans Moog [IF]어제 오후 11:37 'Time' actually takes into account things like decay So it doesn't just increase forever It's close to "Demurrage" in monetary theory 📷 lekanovic어제 오후 11:36 For projects to be able to connect to Polkadot or Cosmos, you need to get the state of the ledger. Will it be possible to get the Tangle state? If this would be possible, then I think it would be SUPER good for IOTA 📷 Hans Moog [IF]어제 오후 11:38 Yeah but polkadot is not connecting other dlts Just inhouse stuff 📷 Hyperware어제 오후 11:39 Is there still a cap on mana so that the rich don't get richer? 📷 Hans Moog [IF]어제 오후 11:39 Yes mana is capped 📷 TangleAccountant어제 오후 11:39 u/HansMoog [IF] My first thought is thatthe evolution of this renting system will lead to several big mana renting companies that pool together tons of token holders mana. That way businesses looking to rent mana just need to deal with a reliable mana renting company for years instead of a new individualevery couple of months (because life happens and you don't know if that individual will need to sell their IOTAs due to personal reasons). Any thoughts on this? 📷 Hans Moog [IF]어제 오후 11:41 u/TangleAccountantyes that is likely - but also not a bad thing - token holders will have a place to get their monthly payout and the companies that want to use the tangle without having tokens have a place to pay 📷 TangleAccountant어제 오후 11:42 Oh I completely agree.That's really cool. I'll take a stab at creating one of those companies in the US. 📷 Hans Moog [IF]어제 오후 11:42 And everybody who wants to run a node themselves or has tokens and wants use the tangle for free can do so But "leachers" that would want to use the network for free won't be able to do so I mean ultimately there will always be "fees", as there is no "free lunch". You have a certain amount of resources that a network can process and you have a certain demand. And that will naturally result in fees based on supply / demand what you can do however is to build a system where the actual users of that system that legitimately want to use it can do so for free, just because they already "invest" enough by having tokens or running infrastructure they are already contributing to the well-being of the network through these two aspects alone it would be stupid to ask those guys for additional fees and mana essentially tries to be such a measure of honesty among the users 📷 Hyperware어제 오후 11:47 It's interesting from an investment perspective that having tokens/mana is like owning a portion of the network. 📷 Hans Moog [IF]어제 오후 11:48 Yeah, you are owning a certain % of the throughput and whatever the price will ultimately be to execute on this network - you will earn proportionally but you have to keep in mind that we are trying to build the most efficient DLT that you could possibly ever build 📷 semibaron어제 오후 11:48 The whole mana (tokens) = share of network throuput sounds very much like EOS tbh Just that EOS uses DPoS 📷 Hans Moog [IF]어제 오후 11:50 yeah i mean there is really not too many new things under the sun - you can just tweak a few things here and there, when it comes to distributing resources DPoS is simply not very nice from a centralization aspect 📷 Hans Moog [IF]어제 오후 11:50 at least not the way EOS does it delegating weights is 1 thing but assuming that the weight will always be in a way that 21 "identities" run the whole network is bad in the current world you see a centralization of power but ultimately we want to build a future where the wealth is more evenly distributed and the same goes for voting power 📷 Hans Moog [IF]어제 오후 11:52 blockchain needs leader selection it only works with such a centralizing component IOTA doesn't need that it's delusional to say that IOTA wouldn't have any such centralization but maybe we get better than just a handselected nodes📷 📷 Phantom3D어제 오후 11:52 How would this affect a regular hodler without a node. Should i keep my tokens elsewere to generate mana and put the tokens to use? 📷 Hans Moog [IF]어제 오후 11:53 you can do whatever you want with your mana just make an account at a node you regularly use and use it to build up a reputation with that node to be able to use your funds for free or run a node yourself or rent it out to companies if you just hodl 📷 semibaron어제 오후 11:54 Will there be a build-in function into the node software / wallet to delegate ("sell") my mana? 📷 Hans Moog [IF]어제 오후 11:55 u/semibaronnot from the start - that would happen on a 2nd layer ------------------------------------------------------------------------------------------------------------ 📷 dom어제 오후 9:49

It's still possible to send transactions even without mana - mana is only used in times of congestion to give the people that have more mana more priority
u/HansMoog [IF] Im sorry Hans, but this is false in the current congestion control algorithm. No mana = no transactions. To be honest, we havent really tried to make it work so that you can sent transactions with no mana during ties with no congestion, but I dont see how you can enable this and still maintain the sybil protection required. u/LuigiVigneri [IF] What do you think?📷

Let's sidebar this discussion and return when we have agreement. Dave has the right idea
Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses. Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes. First, some background. Here is a summary of how custodians make us more secure: Previously, we might give Alice our crypto assets to hold. There were risks:
Alice might take the assets and disappear.
Alice might spend the assets and pretend that she still has them (fractional model).
Alice might store the assets insecurely and they'll get stolen.
Alice might give the assets to someone else by mistake or by force.
Alice might lose access to the assets.
But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
Alice can't take the assets and disappear (unless she asks Bob or never gives them to Bob).
Alice can't spend the assets and pretend that she still has them. (Unless she didn't give them to Bob or asks him for them.)
Alice can't store the assets insecurely so they get stolen. (After all - she doesn't have any control over the withdrawal process from any of Bob's systems, right?)
Alice can't give the assets to someone else by mistake or by force. (Bob will stop her, right Bob?)
Alice can't lose access to the funds. (She'll always be present, sane, and remember all secrets, right?)
See - all problems are solved! All we have to worry about now is:
Bob might take the assets and disappear.
Bob might spend the assets and pretend that he still has them (fractional model).
Bob might store the assets insecurely and they'll get stolen.
Bob might give the assets to someone else by mistake or by force.
Bob might lose access to the assets.
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are! "On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid". "Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since." "As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!" "Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?" "Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party." "Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!" "What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven." "Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!" "We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies. And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often". How many holes have to exist for your funds to get stolen? Just one. Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so? If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security. The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle. And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet? Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds. So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
ANY CERTAINTY BALANCES WEREN'T EXCLUDED. Quadriga's largest account was $70m. 80% of funds are in 20% of accounts (Pareto principle). All it takes is excluding a few really large accounts - and nobody's the wiser. A fractional platform can easily pass any audit this way.
ANY VISIBILITY WHATSOEVER INTO THE CUSTODIANS. BitBuy put out their report before moving all the funds to their custodian and ShakePay apparently can't even tell us who the custodian is. That's pretty important considering that basically all of the funds are now stored there.
ANY IDEA ABOUT THE OTHER EXCHANGES. In order for this to be effective, it has to be the norm. It needs to be "unusual" not to know. If obscurity is the norm, then it's super easy for people like Gerald Cotten and Dave Smilie to blend right in.
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
First report within 1 month of launching, another within 3 months, and further reports at minimum every 6 months thereafter.
No auditor can be repeated within a 12 month period.
All reports must be public, identifying the auditor and the full methodology used.
All auditors must be independent of the firm being audited with no conflict of interest.
Reports must include the percentage of each asset backed, and how it's backed.
The auditor publishes a hash list, which lists a hash of each customer's information and balances that were included. Hash is one-way encryption so privacy is fully preserved. Every customer can use this to have 100% confidence they were included.
If we want more extensive requirements on audits, these should scale upward based on the total assets at risk on the platform, and whether the platform has loaned their assets out.
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever. Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see. It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation. A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7. History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance. Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.) Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive. Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today. Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well. Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do. Facts/background/sources (skip if you like):
The inspiration for the paragraph about splitting wallets was an actual quote from a Canadian company providing custodial services in response to the OSC consultation paper: "We believe that it will be in the in best interests of investors to prohibit pooled crypto assets or ‘floats’. Most Platforms pool assets, citing reasons of practicality and expense. The recent hack of the world’s largest Platform – Binance – demonstrates the vulnerability of participants’ assets when such concessions are made. In this instance, the Platform’s entire hot wallet of Bitcoins, worth over $40 million, was stolen, facilitated in part by the pooling of client crypto assets." "the maintenance of participants (and Platform) crypto assets across multiple wallets distributes the related risk and responsibility of security - reducing the amount of insurance coverage required and making insurance coverage more readily obtainable". For the record, their reply also said nothing whatsoever about multi-sig or offline storage.
In addition to the fact that the $40m hack represented only one "hot wallet" of Binance, and they actually had the vast majority of assets in other wallets (including mostly cold wallets), multiple real cases have clearly demonstrated that risk is still present with multiple wallets. Bitfinex, VinDAX, Bithumb, Altsbit, BitPoint, Cryptopia, and just recently KuCoin all had multiple wallets breached all at the same time, and may represent a significantly larger impact on customers than the Binance breach which was fully covered by Binance. To represent that simply having multiple separate wallets under the same security scheme is a comprehensive way to reduce risk is just not true.
Private insurance has historically never covered a single loss in the cryptocurrency space (at least, not one that I was able to find), and there are notable cases where massive losses were not covered by insurance. Bitpay in 2015 and Yapizon in 2017 both had insurance policies that didn't pay out during the breach, even after a lengthly court process. The same insurance that ShakePay is presently using (and announced to much fanfare) was describe by their CEO himself as covering “physical theft of the media where the private keys are held,” which is something that has never historically happened. As was said with regard to the same policy in 2018 - “I don’t find it surprising that Lloyd’s is in this space,” said Johnson, adding that to his mind the challenge for everybody is figuring out how to structure these policies so that they are actually protective. “You can create an insurance policy that protects no one – you know there are so many caveats to the policy that it’s not super protective.”
The most profitable policy for a private insurance company is one with the most expensive premiums that they never have to pay a claim on. They have no inherent incentive to take care of people who lost funds. It's "cheaper" to take the reputational hit and fight the claim in court. The more money at stake, the more the insurance provider is incentivized to avoid payout. They're not going to insure the assets unless they have reasonable certainty to make a profit by doing so, and they're not going to pay out a massive sum unless it's legally forced. Private insurance is always structured to be maximally profitable to the insurance provider.
The circumvention of multi-sig was a key factor in the massive Bitfinex hack of over $60m of bitcoin, which today still sits being slowly used and is worth over $3b. While Bitfinex used a qualified custodian Bitgo, which was and still is active and one of the industry leaders of custodians, and they set up 2 of 3 multi-sig wallets, the entire system was routed through Bitfinex, such that Bitfinex customers could initiate the withdrawals in a "hot" fashion. This feature was also a hit with the hacker. The multi-sig was fully circumvented.
Bitpay in 2015 was another example of a breach that stole 5,000 bitcoins. This happened not through the exploit of any system in Bitpay, but because the CEO of a company they worked with got their computer hacked and the hackers were able to request multiple bitcoin purchases, which Bitpay honoured because they came from the customer's computer legitimately. Impersonation is a very common tactic used by fraudsters, and methods get more extreme all the time.
A notable case in Canada was the Canadian Bitcoins exploit. Funds were stored on a server in a Rogers Data Center, and the attendee was successfully convinced to reboot the server "in safe mode" with a simple phone call, thus bypassing the extensive security and enabling the theft.
The very nature of custodians circumvents multi-sig. This is because custodians are not just having to secure the assets against some sort of physical breach but against any form of social engineering, modification of orders, fraudulent withdrawal attempts, etc... If the security practices of signatories in a multi-sig arrangement are such that the breach risk of one signatory is 1 in 100, the requirement of 3 independent signatures makes the risk of theft 1 in 1,000,000. Since hackers tend to exploit the weakest link, a comparable custodian has to make the entry and exit points of their platform 10,000 times more secure than one of those signatories to provide equivalent protection. And if the signatories beef up their security by only 10x, the risk is now 1 in 1,000,000,000. The custodian has to be 1,000,000 times more secure. The larger and more complex a system is, the more potential vulnerabilities exist in it, and the fewer people can understand how the system works when performing upgrades. Even if a system is completely secure today, one has to also consider how that system might evolve over time or work with different members.
By contrast, offline multi-signature solutions have an extremely solid record, and in the entire history of cryptocurrency exchange incidents which I've studied (listed here), there has only been one incident (796 exchange in 2015) involving an offline multi-signature wallet. It happened because the customer's bitcoin address was modified by hackers, and the amount that was stolen ($230k) was immediately covered by the exchange operators. Basically, the platform operators were tricked into sending a legitimate withdrawal request to the wrong address because hackers exploited their platform to change that address. Such an issue would not be prevented in any way by the use of a custodian, as that custodian has no oversight whatsoever to the exchange platform. It's practical for all exchange operators to test large withdrawal transactions as a general policy, regardless of what model is used, and general best practice is to diagnose and fix such an exploit as soon as it occurs.
False promises on the backing of funds played a huge role in the downfall of Quadriga, and it's been exposed over and over again (MyCoin, PlusToken, Bitsane, Bitmarket, EZBTC, IDAX). Even today, customers have extremely limited certainty on whether their funds in exchanges are actually being backed or how they're being backed. While this issue is not unique to cryptocurrency exchanges, the complexity of the technology and the lack of any regulation or standards makes problems more widespread, and there is no "central bank" to come to the rescue as in the 2008 financial crisis or during the great depression when "9,000 banks failed".
In addition to fraudulent operations, the industry is full of cases where operators have suffered breaches and not reported them. Most recently, Einstein was the largest case in Canada, where ongoing breaches and fraud were perpetrated against the platform for multiple years and nobody found out until the platform collapsed completely. While fraud and breaches suck to deal with, they suck even more when not dealt with. Lack of visibility played a role in the largest downfalls of Mt. Gox, Cryptsy, and Bitgrail. In some cases, platforms are alleged to have suffered a hack and keep operating without admitting it at all, such as CoinBene.
It surprises some to learn that a cryptographic solution has already existed since 2013, and gained widespread support in 2014 after Mt. Gox. Proof of Reserves is a full cryptographic proof that allows any customer using an exchange to have complete certainty that their crypto-assets are fully backed by the platform in real-time. This is accomplished by proving that assets exist on the blockchain, are spendable, and fully cover customer deposits. It does not prove safety of assets or backing of fiat assets.
If we didn't care about privacy at all, a platform could publish their wallet addresses, sign a partial transaction, and put the full list of customer information and balances out publicly. Customers can each check that they are on the list, that the balances are accurate, that the total adds up, and that it's backed and spendable on the blockchain. Platforms who exclude any customer take a risk because that customer can easily check and see they were excluded. So together with all customers checking, this forms a full proof of backing of all crypto assets.
However, obviously customers care about their private information being published. Therefore, a hash of the information can be provided instead. Hash is one-way encryption. The hash allows the customer to validate inclusion (by hashing their own known information), while anyone looking at the list of hashes cannot determine the private information of any other user. All other parts of the scheme remain fully intact. A model like this is in use on the exchange CoinFloor in the UK.
A Merkle tree can provide even greater privacy. Instead of a list of balances, the balances are arranged into a binary tree. A customer starts from their node, and works their way to the top of the tree. For example, they know they have 5 BTC, they plus 1 other customer hold 7 BTC, they plus 2-3 other customers hold 17 BTC, etc... until they reach the root where all the BTC are represented. Thus, there is no way to find the balances of other individual customers aside from one unidentified customer in this case.
Proposals such as this had the backing of leaders in the community including Nic Carter, Greg Maxwell, and Zak Wilcox. Substantial and significant effort started back in 2013, with massive popularity in 2014. But what became of that effort? Very little. Exchange operators continue to refuse to give visibility. Despite the fact this information can often be obtained through trivial blockchain analysis, no Canadian platform has ever provided any wallet addresses publicly. As described by the CEO of Newton "For us to implement some kind of realtime Proof of Reserves solution, which I'm not opposed to, it would have to ... Preserve our users' privacy, as well as our own. Some kind of zero-knowledge proof". Kraken describes here in more detail why they haven't implemented such a scheme. According to professor Eli Ben-Sasson, when he spoke with exchanges, none were interested in implementing Proof of Reserves.
And yet, Kraken's places their reasoning on a page called "Proof of Reserves". More recently, both BitBuy and ShakePay have released reports titled "Proof of Reserves and Security Audit". Both reports contain disclaimers against being audits. Both reports trust the customer list provided by the platform, leaving the open possibility that multiple large accounts could have been excluded from the process. Proof of Reserves is a blockchain validation where customers see the wallets on the blockchain. The report from Kraken is 5 years old, but they leave it described as though it was just done a few weeks ago. And look at what they expect customers to do for validation. When firms represent something being "Proof of Reserve" when it's not, this is like a farmer growing fruit with pesticides and selling it in a farmers market as organic produce - except that these are people's hard-earned life savings at risk here. Platforms are misrepresenting the level of visibility in place and deceiving the public by their misuse of this term. They haven't proven anything.
Fraud isn't a problem that is unique to cryptocurrency. Fraud happens all the time. Enron, WorldCom, Nortel, Bear Stearns, Wells Fargo, Moser Baer, Wirecard, Bre-X, and Nicola are just some of the cases where frauds became large enough to become a big deal (and there are so many countless others). These all happened on 100% reversible assets despite regulations being in place. In many of these cases, the problems happened due to the over-complexity of the financial instruments. For example, Enron had "complex financial statements [which] were confusing to shareholders and analysts", creating "off-balance-sheet vehicles, complex financing structures, and deals so bewildering that few people could understand them". In cryptocurrency, we are often combining complex financial products with complex technologies and verification processes. We are naïve if we think problems like this won't happen. It is awkward and uncomfortable for many people to admit that they don't know how something works. If we want "money of the people" to work, the solutions have to be simple enough that "the people" can understand them, not so confusing that financial professionals and technology experts struggle to use or understand them.
For those who question the extent to which an organization can fool their way into a security consultancy role, HB Gary should be a great example to look at. Prior to trying to out anonymous, HB Gary was being actively hired by multiple US government agencies and others in the private sector (with glowing testimonials). The published articles and hosted professional security conferences. One should also look at this list of data breaches from the past 2 years. Many of them are large corporations, government entities, and technology companies. These are the ones we know about. Undoubtedly, there are many more that we do not know about. If HB Gary hadn't been "outted" by anonymous, would we have known they were insecure? If the same breach had happened outside of the public spotlight, would it even have been reported? Or would HB Gary have just deleted the Twitter posts, brought their site back up, done a couple patches, and kept on operating as though nothing had happened?
In the case of Quadriga, the facts are clear. Despite past experience with platforms such as MapleChange in Canada and others around the world, no guidance or even the most basic of a framework was put in place by regulators. By not clarifying any sort of legal framework, regulators enabled a situation where a platform could be run by former criminal Mike Dhanini/Omar Patryn, and where funds could be held fully unchecked by one person. At the same time, the lack of regulation deterred legitimate entities from running competing platforms and Quadriga was granted a money services business license for multiple years of operation, which gave the firm the appearance of legitimacy. Regulators did little to protect Canadians despite Quadriga failing to file taxes from 2016 onward. The entire administrative team had resigned and this was public knowledge. Many people had suspicions of what was going on, including Ryan Mueller, who forwarded complaints to the authorities. These were ignored, giving Gerald Cotten the opportunity to escape without justice.
There are multiple issues with the SOC II model including the prohibitive cost (you have to find a third party accounting firm and the prices are not even listed publicly on any sites), the requirement of operating for a year (impossible for new platforms), and lack of any public visibility (SOC II are private reports that aren't shared outside the people in suits).
Securities frameworks are expensive. Sarbanes-Oxley is estimated to cost $5.1 million USD/yr for the average Fortune 500 company in the United States. Since "Fortune 500" represents the top 500 companies, that means well over $2.55 billion USD (~$3.4 billion CAD) is going to people in suits. Isn't the problem of trust and verification the exact problem that the blockchain is supposed to solve?
To use Quadriga as justification for why custodians or SOC II or other advanced schemes are needed for platforms is rather silly, when any framework or visibility at all, or even the most basic of storage policies, would have prevented the whole thing. It's just an embarrassment.
We are now seeing regulators take strong action. CoinSquare in Canada with multi-million dollar fines. BitMex from the US, criminal charges and arrests. OkEx, with full disregard of withdrawals and no communication. Who's next?
We have a unique window today where we can solve these problems, and not permanently destroy innovation with unreasonable expectations, but we need to act quickly. This is a unique historic time that will never come again.

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain. The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.
The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions. When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved. This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency. Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
1.1 OVERVIEW ABOUT ARYACOIN
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community. Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details. Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda. Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified. Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin. Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim. Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details. Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time. According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public. In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks. AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.
1.1.1 ARYACOIN HISTORY
Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team. Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin. “We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said. Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC. Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees. “We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.” “One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”. “So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.” “We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.”
1.1.2 ARYACOIN’S MAIN GOAL
Aryacoin’s main goal is to educate people and give them the freedom to use cryptocurrency in any way they want. Aryacoin empowers the users to transfer, pay, trade cryptocurrency from any country around the globe. Platforms that have been created by Aryacoin Team, as well as those that will go live in future, operate on the same principle and exclude absolutely no one.
1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE
Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur. Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.
1.1.4 BENEFITS OF USING ARYACOIN
Aryacoin solution offers the following benefits:
Real-time update: whether you’re going on a holiday or a business trip, no problem. You can access your coins all over the world.

1.1.5 ARYACOIN FEATURES
1. Anonymity The coin provides decent level of anonymity for all its users. The users can send their transactions to any of the public nodes to be broadcasted , the transaction sent to the nodes should be signed by the private key of the sender address . This allows the users to use the coin anywhere any time , sending transactions directly to the node allows users from any place and country . 2. Real Life Usage aryacoin’s team is continuously developing new and innovative ways to use the coins , they are currently developing exchanges where the users can exchange the coins without any fees and any restrictions . They also are currently developing other innovative technologies, which would allow users to spend our coins everywhere and anywhere. 3. Offline Exchanges They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future! 4. Transactions When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending. 5. Business Partner with Simplex Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries. In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020. Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.
1.1.6 WHY CHOOSE ARYACOIN?
If you want to use a cryptocurrency that allows you to keep your privacy online even when buying and selling the coins, the Aryacoin team claims that AYA is the way to go. Aryacoin is putting in the work: with more ways to buy and sell, and fixing the issues that were present in the original Bitcoin, plus pushing the boundaries with innovative solutions in cryptocurrencies. You can get started using Aryacoin (AYA) payments simply by having a CoinPayments account!
1.1.7 ARYANA CENTRALIZED EXCHANGE
Aryana, the first Iranian exchange is a unique platform with the following features:
The first real international Persian exchange that obtains international licenses and is listed in CoinMarketCap.
The first Iranian exchange that has been cooperating with a legal and European exchange for 3 years.
The possibility of trading in Tomans (available currency in Iran) at the user’s desired price and getting rid of the transaction prices imposed by domestic sites inside Iran.
There is an internal fee payment plan by Iranian domestic banks for depositing and withdrawing Tomans for Aryacoin holders in Aryana Exchange.
The number that you see on the monitor and in your account will be equal to the number that is transferred to your bank account without a difference of one Rial.
The last but not least, noting the fact that there is a trading in Tomans possibility in Aryana exchange.
Aryana Exchange is using the most powerful, fastest, and most expensive server in the world, Google Cloud Platform (GCP), which is currently the highest quality server for an Iranian site, so that professional traders do not lag behind the market even for a second. The feature of Smart Trading Robots is one of the most powerful features for digital currency traders. Digital cryptocurrency traders are well aware of how much they will benefit from smart trading robots. In the Aryana exchange, it is possible to connect exchange user accounts to intelligent trading bots and trade even when they are offline. The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.
1.1.8 HOW DOES ARYACOIN WORK?
Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.
2. ARYACOIN TECHNOLOGY
They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash. For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it. The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.
The steps to run the network are as follows:
New transactions are broadcast to all nodes.
Each node collects new transactions into a block.
Each node works on finding a difficult proof-of-work for its block.
When a node finds a proof-of-work, it broadcasts the block to all nodes.
Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.
2.3 AYAPAY PAYMENT SERVICES GATEWAY:
According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world. This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee. In other similar systems or even systems such as PayPal, money is stored in the user account.
2.4 CONSENSUS ALGORITHM IN ARYACOIN
The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.
2.5 DOUBLE-SPEND PROBLEM AND SOLUTION
One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.

How DAO users can truly control their voting rights
https://blockchaintopbuzz.medium.com/how-dao-users-can-truly-control-their-voting-rights-f945c9c6b65e Aelf proposed a solution that gives the control of the voting rights back to users by classifying token permissions. As of today, there are still few complete businesses. In addition to mining and building trading platforms, it is difficult to create a complete business model. Moreover, various trading platforms have gradually grown into enterprises with comprehensive products in the blockchain industry, including wallets, nodes, lending, mining pools, etc. At the same time, cloud services can reduce the cost of building small exchanges, but they can also lead to big trading platforms monopolizing data. For example, some Internet companies provide free cloud services in order to collect more valuable data. Currently, Ethereum, which has the richest DeFi ecosystem, is gradually upgrading to V2.0, and its consensus protocol will also be upgraded to PoS. Governance voting can be regarded as the most important feature in the PoS ecosystem. This year, Yearn.Finance rose to sudden prominence. But due to the governance problem, its community members initiated a hard fork, resulting in YFII. Another DeFi project, YAM, had a unfixable rebase function error. The founding team apologized for the error and announced a ‘Migration Plan’, which will turn the project over to the community. For a while, governance voting became all the rage. However, the increasingly bigger trading platforms have been criticized by users in governance voting. Is there a proper solution to handling the relationship between the trading platform and governance voting?
What will we lose when trading platforms monopolize the blockchain industry?
In June 2018, during the BP node election before the EOS mainnet launch, node voting began to have a crisis of confidence between token holders and the trading platform. it is widely believed that the top 20 holders of trading platform wallets held about 40% of all the EOS in circulation. Since then, many trading platforms have enabled the “User Authorization” interface. EOS holders can authorize the token voting rights to the trading platform, who will vote on behalf of the users. The rule caused a backlash from users, forcing these trading platforms to change the rule immediately so that EOS holders could vote on their preferred BP nodes. After the EOS BP node votes, whether the trading platform has the token voting right has been occasionally discussed, but fewhave noticed it. Two years later, Justin Sun, founder of TRON, made a commercial acquisition of Steemit, a decentralized social networking platform. After the acquisition was announced, the Steemit community launched a soft fork to resist the project being controlled by TRON. However, Justin Sun voted with the support of trading platforms such as Binance, Huobi and Poloniex to prevent a soft fork. After being questioned by users, Binance and Huobi said that they would no longer interfere in the voting of the Steemit community. However, hkdev 404 of the Steem community again reveived votes from Huobi accounts. It is said that nearly 40 million votes were cast during the incident, accounting for about 10% of the total circulation of STEEM tokens. There is no doubt that when the trading platform monopolizes the industry, we will lose our voting right. How do we defend our voting rights The fact that the ownership of the tokens belongs to the holders is indisputable, but what about the voting rights of the tokens deposited on the trading platform? How can we defend our voting rights after trading platforms have monopolized the industry?
Trading Platform Model
Traditional centralized trading platforms will assign to each user a separate deposit address. After depositing, the depositedamount will be added into the cold wallet and hot wallet. When users want to withdraw their tokens, the trading platform will transfer the tokens out of the hot wallet. If there is insufficient balance in the hot wallet, then the tokens will be transferred from the cold wallet to the hot wallet, and then be withdrawn. Under the traditional centralized trading platform model, once users transfer their tokens into a trading platform, it means thetoken ownership (including voting rights) is also transferred to that trading platform. The aelf solution: classify token permissions and claim back voting rights For the issue of “voting rights” between token holders and centralized trading platforms, aelf, a decentralized cloud computing blockchain network, has proposed a solution: to establish an aelf Centre Asset Management Contract on the chain. The contract can limit the funds entering the exchange and define different permissions to control the assets. The main feature of the aelf Centre Asset Management Contract is to create the “Main Virtual Address of the Trading Platform”. Each exchange has a main virtual address, which can only be used for transfer operation, but not for voting, trading and other operations. As a result, the exchange cannot misappropriate users’ assets for voting. At the same time, the assets of the primary virtual address are publicly available on the chain, which makes it more difficult for the exchange to misappropriate assets. At the same time, the aelf Centre Asset Management Contract also has the function of “address definition”. The exchange can open different permissions to different addresses, such as opening different permissions according to the amount, transactions exceeding a certain amount can only be given the greenlight by using multiple signatures, and the assets can be frozen through the contract when the assets of the trading platform are stolen, etc. For the users of the trading platform, the access of the trading platform to the aelf Center Asset Management Contract function will not undermine user experience. The virtual system address of the aelf Center Asset Management Contract will assign a virtual address to each user, which offers the same user experience as the traditional mode. For the trading platform, each deposit address constructed by the virtual address system is generated by the algorithm and does not need to be carried out on the blockchain. This means that the trading platform does not need to manage a large number of private keys, and there is no risk that the private keys will be lost. On the most important “voting rights” issue, the aelf Center Asset Management Contract will assign to each user a separate virtual address for voting: Voting address = Hash (Exchange Main Address + Token + “VOTE”) Voting process: the tokens are transferred from the main virtual address of the exchange to the special “voting address” for voting, and are then voted. After voting, the tokens are withdrawn from the voting address back to the main virtual address. We can see that the aelf Centre Asset Management Contract proposed by aelf can improve the efficiency of the trading platform without affecting user experience. In addition, it solves the problem that users would lose their voting rights. According to the data on Crypto Mode, the market value of PoS tokens has exceeded $33 billion without counting Ethereum. In the field of crypto, it is the biggest ecosystem next to Bitcoin. The most important function of PoS is vote staking. faced with bigtrading platforms, if the status quo continues, retail investors will gradually lose their “voting rights” that belong to them. Comparison of Market Value of PoS tokens (Source: Crypto Mode) The emergence of DAO offers an alternative to trading platforms who misappropriate users’ tokens, but it still can not change this situation. Of course, DAO will not die out. Small communities will still use DAO for community governance. The idea behind the design of aelf is to start from the underlying trading platform and solve this issue at the source. Whether the solution can work still takes time. However, as a member of the crypto industry, we should understand the importance of “voting rights”, and cannot allow the exchange to seize our rights at will. Recently, aelf has also announced its DeFi plan, which includes a new blockchain 3.0 project with a large number of new technical features, such as cross chain function, virtual address and cloud services. Aelf also proposed a set of interoperability solutions with ERC-20 tokens. It can directly access the ETH ecosystem, allow ETH-based applications and wallets to directly access it, and maintain the interoperability with ETH. And aelf will provide a high-performance smart contract operation platform and cloud services that can support cross chain interaction. Users on major cloud servers can easily run aelf’s services and adjust the scale of cloud according to their own business needs. The implementation of a slew of tools, cloud services and interoperability solutions developed by aelf means that centralized transactions can be directly connected to the aelf network, realizing one-click adaptation to the DeFi ecosystem. With aelf, CeFi and DeFi are able to learn from and complement each other.
