I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!
I posted this on /cryptotechnology . It attracted quite a bit of upvotes but not many potential contributors. Someone mentioned I should try this sub. I read the rules and it seems to fit within them. Hope this kind of post is alright here... EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors. TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [email protected] . Thanks in advance! Hi guys, For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction. The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract. The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data. The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block. To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block. I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors. The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract. There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive). The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only. I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport. When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software. The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create: A logistic and transportation company A delivery company A company that buy and sell real estate options A company that manage real estate A software development company A world-wide fiat money transfer company A payment processor company We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money exchanges. We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche. I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper. If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [email protected] . If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed. Thanks all in advance! P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members. Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.
Maybe it's time to discuss bitcoin's history again. Credit to u/singularity87 for the original post over 3 years ago. People should get the full story of bitcoin because it is probably one of the strangest of all reddit subs. bitcoin, the main sub for the bitcoin community is held and run by a person who goes by the pseudonym u/theymos. Theymos not only controls bitcoin, but also bitcoin.org and bitcointalk.com. These are top three communication channels for the bitcoin community, all controlled by just one person. For most of bitcoin's history this did not create a problem (at least not an obvious one anyway) until around mid 2015. This happened to be around the time a new player appeared on the scene, a for-profit company called Blockstream. Blockstream was made up of/hired many (but not all) of the main bitcoin developers. (To be clear, Blockstream was founded before mid 2015 but did not become publicly active until then). A lot of people, including myself, tried to point out there we're some very serious potential conflicts of interest that could arise when one single company controls most of the main developers for the biggest decentralised and distributed cryptocurrency. There were a lot of unknowns but people seemed to give them the benefit of the doubt because they were apparently about to release some new software called "sidechains" that could offer some benefits to the network. Not long after Blockstream came on the scene the issue of bitcoin's scalability once again came to forefront of the community. This issue came within the community a number of times since bitcoins inception. Bitcoin, as dictated in the code, cannot handle any more than around 3 transactions per second at the moment. To put that in perspective Paypal handles around 15 transactions per second on average and VISA handles something like 2000 transactions per second. The discussion in the community has been around how best to allow bitcoin to scale to allow a higher number of transactions in a given amount of time. I suggest that if anyone is interested in learning more about this problem from a technical angle, they go to btc and do a search. It's a complex issue but for many who have followed bitcoin for many years, the possible solutions seem relatively obvious. Essentially, currently the limit is put in place in just a few lines of code. This was not originally present when bitcoin was first released. It was in fact put in place afterwards as a measure to stop a bloating attack on the network. Because all bitcoin transactions have to be stored forever on the bitcoin network, someone could theoretically simply transmit a large number of transactions which would have to be stored by the entire network forever. When bitcoin was released, transactions were actually for free as the only people running the network were enthusiasts. In fact a single bitcoin did not even have any specific value so it would be impossible set a fee value. This meant that a malicious person could make the size of the bitcoin ledger grow very rapidly without much/any cost which would stop people from wanting to join the network due to the resource requirements needed to store it, which at the time would have been for very little gain. Towards the end of the summer last year, this bitcoin scaling debate surfaced again as it was becoming clear that the transaction limit for bitcoin was semi regularly being reached and that it would not be long until it would be regularly hit and the network would become congested. This was a very serious issue for a currency. Bitcoin had made progress over the years to the point of retailers starting to offer it as a payment option. Bitcoin companies like, Microsoft, Paypal, Steam and many more had began to adopt it. If the transaction limit would be constantly maxed out, the network would become unreliable and slow for users. Users and businesses would not be able to make a reliable estimate when their transaction would be confirmed by the network. Users, developers and businesses (which at the time was pretty much the only real bitcoin subreddit) started to discuss how we should solve the problem bitcoin. There was significant support from the users and businesses behind a simple solution put forward by the developer Gavin Andreesen. Gavin was the lead developer after Satoshi Nakamoto left bitcoin and he left it in his hands. Gavin initially proposed a very simple solution of increasing the limit which was to change the few lines of code to increase the maximum number of transactions that are allowed. For most of bitcoin's history the transaction limit had been set far far higher than the number of transactions that could potentially happen on the network. The concept of increasing the limit one time was based on the fact that history had proven that no issue had been cause by this in the past. A certain group of bitcoin developers decided that increasing the limit by this amount was too much and that it was dangerous. They said that the increased use of resources that the network would use would create centralisation pressures which could destroy the network. The theory was that a miner of the network with more resources could publish many more transactions than a competing small miner could handle and therefore the network would tend towards few large miners rather than many small miners. The group of developers who supported this theory were all developers who worked for the company Blockstream. The argument from people in support of increasing the transaction capacity by this amount was that there are always inherent centralisation pressure with bitcoin mining. For example miners who can access the cheapest electricity will tend to succeed and that bigger miners will be able to find this cheaper electricity easier. Miners who have access to the most efficient computer chips will tend to succeed and that larger miners are more likely to be able to afford the development of them. The argument from Gavin and other who supported increasing the transaction capacity by this method are essentially there are economies of scale in mining and that these economies have far bigger centralisation pressures than increased resource cost for a larger number of transactions (up to the new limit proposed). For example, at the time the total size of the blockchain was around 50GB. Even for the cost of a 500GB SSD is only $150 and would last a number of years. This is in-comparison to the $100,000's in revenue per day a miner would be making. Various developers put forth various other proposals, including Gavin Andresen who put forth a more conservative increase that would then continue to increase over time inline with technological improvements. Some of the employees of blockstream also put forth some proposals, but all were so conservative, it would take bitcoin many decades before it could reach a scale of VISA. Even though there was significant support from the community behind Gavin's simple proposal of increasing the limit it was becoming clear certain members of the bitcoin community who were part of Blockstream were starting to become increasingly vitriolic and divisive. Gavin then teamed up with one of the other main bitcoin developers Mike Hearn and released a coded (i.e. working) version of the bitcoin software that would only activate if it was supported by a significant majority of the network. What happened next was where things really started to get weird. After this free and open source software was released, Theymos, the person who controls all the main communication channels for the bitcoin community implemented a new moderation policy that disallowed any discussion of this new software. Specifically, if people were to discuss this software, their comments would be deleted and ultimately they would be banned temporarily or permanently. This caused chaos within the community as there was very clear support for this software at the time and it seemed our best hope for finally solving the problem and moving on. Instead a censorship campaign was started. At first it 'all' they were doing was banning and removing discussions but after a while it turned into actively manipulating the discussion. For example, if a thread was created where there was positive sentiment for increasing the transaction capacity or being negative about the moderation policies or negative about the actions of certain bitcoin developers, the mods of bitcoin would selectively change the sorting order of threads to 'controversial' so that the most support opinions would be sorted to the bottom of the thread and the most vitriolic would be sorted to the top of the thread. This was initially very transparent as it was possible to see that the most downvoted comments were at the top and some of the most upvoted were at the bottom. So they then implemented hiding the voting scores next to the users name. This made impossible to work out the sentiment of the community and when combined with selectively setting the sorting order to controversial it was possible control what information users were seeing. Also, due to the very very large number of removed comments and users it was becoming obvious the scale of censorship going on. To hide this they implemented code in their CSS for the sub that completely hid comments that they had removed so that the censorship itself was hidden. Anyone in support of scaling bitcoin were removed from the main communication channels. Theymos even proudly announced that he didn't care if he had to remove 90% of the users. He also later acknowledged that he knew he had the ability to block support of this software using the control he had over the communication channels. While this was all going on, Blockstream and it's employees started lobbying the community by paying for conferences about scaling bitcoin, but with the very very strange rule that no decisions could be made and no complete solutions could be proposed. These conferences were likely strategically (and successfully) created to stunt support for the scaling software Gavin and Mike had released by forcing the community to take a "lets wait and see what comes from the conferences" kind of approach. Since no final solutions were allowed at these conferences, they only served to hinder and splinter the communities efforts to find a solution. As the software Gavin and Mike released called BitcoinXT gained support it started to be attacked. Users of the software were attack by DDOS. Employees of Blockstream were recommending attacks against the software, such as faking support for it, to only then drop support at the last moment to put the network in disarray. Blockstream employees were also publicly talking about suing Gavin and Mike from various different angles simply for releasing this open source software that no one was forced to run. In the end Mike Hearn decided to leave due to the way many members of the bitcoin community had treated him. This was due to the massive disinformation campaign against him on bitcoin. One of the many tactics that are used against anyone who does not support Blockstream and the bitcoin developers who work for them is that you will be targeted in a smear campaign. This has happened to a number of individuals and companies who showed support for scaling bitcoin. Theymos has threatened companies that he will ban any discussion of them on the communication channels he controls (i.e. all the main ones) for simply running software that he disagrees with (i.e. any software that scales bitcoin). As time passed, more and more proposals were offered, all against the backdrop of ever increasing censorship in the main bitcoin communication channels. It finally come down the smallest and most conservative solution. This solution was much smaller than even the employees of Blockstream had proposed months earlier. As usual there was enormous attacks from all sides and the most vocal opponents were the employees of Blockstream. These attacks still are ongoing today. As this software started to gain support, Blockstream organised more meetings, especially with the biggest bitcoin miners and made a pact with them. They promised that they would release code that would offer an on-chain scaling solution hardfork within about 4 months, but if the miners wanted this they would have to commit to running their software and only their software. The miners agreed and the ended up not running the most conservative proposal possible. This was in February last year. There is no hardfork proposal in sight from the people who agreed to this pact and bitcoin is still stuck with the exact same transaction limit it has had since the limit was put in place about 6 years ago. Gavin has also been publicly smeared by the developers at Blockstream and a plot was made against him to have him removed from the development team. Gavin has now been, for all intents an purposes, expelled from bitcoin development. This has meant that all control of bitcoin development is in the hands of the developers working at Blockstream. There is a new proposal that offers a market based approach to scaling bitcoin. This essentially lets the market decide. Of course, as usual there has been attacks against it, and verbal attacks from the employees of Blockstream. This has the biggest chance of gaining wide support and solving the problem for good. To give you an idea of Blockstream; It has hired most of the main and active bitcoin developers and is now synonymous with the "Core" bitcoin development team. They AFAIK no products at all. They have received around $75m in funding. Every single thing they do is supported by theymos. They have started implementing an entirely new economic system for bitcoin against the will of it's users and have blocked any and all attempts to scaling the network in line with the original vision. Although this comment is ridiculously long, it really only covers the tip of the iceberg. You could write a book on the last two years of bitcoin. The things that have been going on have been mind blowing. One last thing that I think is worth talking about is the u/bashco's claim of vote manipulation. The users that the video talks about have very very large numbers of downvotes mostly due to them having a very very high chance of being astroturfers. Around about the same time last year when Blockstream came active on the scene every single bitcoin troll disappeared, and I mean literally every single one. In the years before that there were a large number of active anti-bitcoin trolls. They even have an active sub buttcoin. Up until last year you could go down to the bottom of pretty much any thread in bitcoin and see many of the usual trolls who were heavily downvoted for saying something along the lines of "bitcoin is shit", "You guys and your tulips" etc. But suddenly last year they all disappeared. Instead a new type of bitcoin user appeared. Someone who said they were fully in support of bitcoin but they just so happened to support every single thing Blockstream and its employees said and did. They had the exact same tone as the trolls who had disappeared. Their way to talking to people was aggressive, they'd call people names, they had a relatively poor understanding of how bitcoin fundamentally worked. They were extremely argumentative. These users are the majority of the list of that video. When the 10's of thousands of users were censored and expelled from bitcoin they ended up congregating in btc. The strange thing was that the users listed in that video also moved over to btc and spend all day everyday posting troll-like comments and misinformation. Naturally they get heavily downvoted by the real users in btc. They spend their time constantly causing as much drama as possible. At every opportunity they scream about "censorship" in btc while they are happy about the censorship in bitcoin. These people are astroturfers. What someone somewhere worked out, is that all you have to do to take down a community is say that you are on their side. It is an astoundingly effective form of psychological attack.
Three suggestions for better boundaries between Monero and Tari
I write this as a multi-year Monero contributor to the subreddit, the CCS, and minor commits to both the CLI and GUI. However, my Reddit account is newish since I regularly delete my Reddit account every six months or so out of privacy concerns, so let my words in this post act as proof of my grasp of Monero and our community's values. I have been increasingly confused by how intermingled the goals of Monero have become with Tari. Naturally, I could care less if someone wants to merge-mine with Monero. But last week we had dEBRUYNE, longtime excellent mod of this subreddit, break the subreddit's own rules to announce Tari's testnet. So naturally it feels like the Monero community is being invited to align itself with Tari, both alongside Tari's development and its eventual goals. Yet I don't feel like the Monero community is fully aware of how this conflation has the potential to degrade the purity of our community, so that's why I am writing this post today. On the one hand you have Monero, perhaps the only pure cryptocurrency project left in the entire space. Bitcoin development has declined to a crawl. Yes, regular commits to its code happen all the time, but fundamentally they have become a traceable surveillance coin, and make no major efforts to change this. Greg Maxwell's Confidential Transactions are just sitting there on the shelf, waiting to be implemented. It's sad, really. Thankfully, there is us. There is Monero. We have all of the benefits of Bitcoin in that we were fairly launched (no premine, founder's share, etc), are decentralized, PoW, and open source. Further our culture reflects the culture of Bitcoin's origins. There is no price talk in Monero. No memes. (Bitcoin's subreddit is overwhelmed with price memes, a harbinger of a dying coin.) Indeed, Monero's community is first passionate about the technology inside it. Some of the most upvoted posts in this sub are actual gd pull requests. So wonderful. I think back to how painfully long it took us to complete the GUI. So many of us were so focused on getting the CLI right that the GUI was delayed for (I think) almost two years. There are precious few coins like that these days. Namecoin is a wonderful exception. Jeremy Rand's recent presentation on how Namecoin has been implented in the Tor-browser is perhaps the most exciting news in cryptoland all year. Unlike 95% of the burning crypto dumpster fire, people may soon actually use Namecoin, typing something like Monero.bit instead of a long difficult aasldkfasdlkfjadlkfj.onion address. And then you have everybody else. 95% of the crypto garbage out there is fundamentally useless if not a straight up scam. Most of the stuff falls into 2 different camps of crap: (Crap 1) useless slick coins with massive marketing budgets, and (Crap 2) reskinned forks. 95% of the garbage out there cares first and foremost about how it appears on the surface, because: the first goal for most cryptos is not making something useful, it's making money. You can have a coin like Dash that "innovates" a PoW by stringing a bunch of hash functions together to make it's X11 algo, but since the wallet software itself impresses people, they don't care. Who cares if there is fundamental collision potential in X11 that could break the coin in a single block? Everything looks sliiick. In short, you can tell if a cryptocurrency is healthy or not if its first goal is making money or making something useful. Thankfully Tari does not seem to be as bad as 95% of the stuff out there. A cursory glance at their repo makes it seem like Fluffypony found talented devs who know their stuff. Further, I think the idea of merge-mining alongside Monero is quite smart. I am a huge fan of Tevador and hyc and the work they did on RandomX, so anything that champions their creation is welcome to me! My hope is we have dozens of merge-mined RandomX coins in the coming decades. Our hash rate will only increase, and the security of our chain will improve. Furthermore, I think Fluffypony himself is a guy with a lot of integrity, so I actually feel a degree of trust towards Tari that I wouldn't naturally feel. The issue is Tari's goals. I say this dispassionately: I am uncertain if Tari's central goal is to make something useful or to make money. Here's an article in Blockchain News announcing Tari. In it, they describe what Tari's software will hopefully do:
in our digital world, these restrictions are unduly limiting for both businesses and consumers, making it costly, difficult, or impossible for digital assets to be resold or transferred,” the announcement stated. “For businesses, this means missing out on the tens of billions of dollars generated each year from secondary resale and trading of the digital goods they issue. For consumers, this means never having true ownership of their digital assets, despite having earned or paid for them.”
Sounds ok. Who wouldn't want the ability to trade scarce digital assets with programmed rules? I certainly would. However, farther down the page you have this:
... those involved with the project include John Pleasants, the former CEO of Ticketmaster and the venture firms Redpoint, Trinity Ventures, Canaan Partners, Slow Ventures, Aspect Ventures, DRW Ventures, Blockchain Capital, Pantera, and Multicoin Capital.
Here is where things get a little hairy, and why I am nervous about the pump-culture of crypto leaking into the tech-culture of Monero. Redpoint is a backer of the scammy gambling website Draft Kings. Blockchain Capital is a backer of Coinbase and Ripple. Pantera put up some of the cash that made ZCash happen. I don't know about you, but it makes me squirm a bit to see Tari's logo alongside ZCash and Ripple. Naturally, the terms of their VC investments are somewhere in black and white, yet there is nothing anywhere on the Tari website about the emission schedule of the coin. In fact, unlike most VC backed crypto out there, Tari doesn't even list their investors. They used to list it in their FAQ as seen on archive.org, but have since removed it. Monero is one of the most hopeful things in the world right now, and it has this special status for me because it cares first and foremost about the technology it is innovating. Decentralized private open-sourced cash. It's an incredible wonderful future that we're all making together. Nothing like Monero has ever existed. But it is more fragile than people realize. It can be slowly killed. This community can eventually become like Bitcoin, stuck in price-memes, if the culture gets sucked away from technology and into profit making. Is it possible for Tari to accept VC money and be solely focused on the technology of a product? Theoretically, yes. But it's not easy. I've had to work with a few small Silicon Valley companies who also accepted VC cash, and returns to their shareholders were a constant source of pressure on them. Will it be for Tari? Monero needed many years to be awkward and small in order to strengthen itself to be the sizable functional coin it is today. Does Tari have this same patience, or will the VCs need payouts sooner than that? If Fluffypony's main goal in Tari is to help people trade digital assets then why didn't he simply launch Tari like Monero, free and open source (FOSS)? Namecoin is FOSS and merge-mined; it has no VC backers. As a worst-case scenario, how long will it be before Tari is "given back to the community", as so many VC-inspired coins have done? Dead code repos all over the corners of cryptoland, discarded after the venture capital firms dumped their premine and took off. There are a lot of unanswered questions here. In closing, I have three suggestions:
Fluffypony should publish the emission schedule as soon as he can, so Tari’s fans can know if there is a premine/founders-share/etc. And perhaps be transparent about how their venture capital investors are being compensated.
People here should think critically before they get involved Tari. It has a different ethos than Monero.
Despite the Fluffypony connection, Rule #4 should be enforced, disallowing posts promoting merge-mined coins like Tari from this forum. If Tari is allowed in this forum, we need our moderators to be honest about whether or not they are investors in Tari and have a conflict of interest. That said, most mods are anonymous, so it's actually impossible to enforce this disclosure. So I guess just enforce Rule #4.
The team’s overall technical background is good, and the CTO and CEO of the project have rich experience in related industries;
The current business scope of CoinEx has been expanded, and the development of the public chain has a decisive role in promoting the development of the exchange business;
The project operation information is transparent, and the development process is consistent with the road map;
The unlocking schedule is clear, and the token held by the team will be unlocked continuously in the next five years;
The project uses POS consensus mechanism. At present, it has been launched on the main network, and the block time is stable, between 2–3 seconds.
It is not clear enough yet whether the trichain operation planning can achieve the project’s development goals;
There is limited information on implementation details about cross-chain and other related technologies, and the development status needs to be assessed based on the later project development disclosure information;
The team currently hold a large share of the token, hence the distribution of tokens is relatively concentrated;
There are few application scenarios for project tokens, and more ecosystem scenarios need to be developed;
As a deflationary token, CET needs to be balanced by dealing with the contradiction between public chain users and token holders.
The development of CoinEx Chain contributes to the future development of CoinEx’s centralized and decentralized exchanges; the concept of trichain operation simplifies the functions of each chain, improving their performance. At present, there are few exchanges working on the public chain, and no fierce competition has occurred.
Considering the status and development prospects of the project, TokenInsight gives CoinEx a rating of BB with a stable outlook.
1. Multidimensional evaluation
2. Project analysis
CoinEx (CoinEx Technology Limited) was established in December 2017 and is headquartered in Hong Kong, China. It is a sub-brand of the ViaBTC mining pool. At present, CoinEx’s business scope includes CoinEx exchange, CoinEx public chain, and CoinEx decentralized exchange. The current development focus of the CoinEx platform are public chain and exchange. The main purpose of the public chain is to build a decentralized exchange (DEX) infrastructure and an ecosystem around DEX. CoinEx business structure，Source: CoinEx; TokenInsight
“ CoinEx Chain uses the parallel operation of three chains which are DEX, Smart, and Privacy, as well as cross-chain technologies to create a rich decentralized exchange ecosystem and blockchain financial infrastructure. The core of CoinEx’s early business was the exchange, consisted of two major categories which were spot and derivatives trading. Currently, there are 123 trading currencies online, covering 302 trading pairs. On June 28, 2019, CoinEx released the CoinEx Chain public chain white paper, aiming to build a decentralized trading system (CoinEx DEX) with community-based operations and transparent transaction rules, and providing user-controlled asset trading scenario by the highest technical standards in the industry; CoinEx Chain has become another development focus of CoinEx. CoinEx Token (CET), which was originally a native token of the CoinEx exchange, will also be developed mainly as a built-in token of the public chain. CoinEx Chain is a public chain based on the Tendermint consensus protocol and Cosmos SDK, and it uses POS mechanism. CoinEx Chain plans to support 42 nodes when the project starts, and any entity in the ecosystem can participate in the validator’s campaign by staking CET. CoinEx Chain will use the new block reward and the transaction fee contained in the block as the reward for running the node. CoinEx Chain has developed three public chains with different positioning and different functions in order to meet the needs of blockchain transactions for transaction performance, smart contracts, and privacy protection at the same time. They operate in parallel and collaborate with each other through cross-chain technology. At present, the block time of the public chain is between 2–3 seconds. According to the observation of TokenInsight, the block time is stable, but the number of transactions through the CoinEx public chain is still low at present, the number of transactions in 24 hours is about 30,000; The TPS on public chain disclosed by CoinEx can reach up to 1500 per second. CoinEx Chain uses a trichain parallel model to build a more vibrant ecosystem around DEX. The three chains are DEX public chain, Smart public chain, and Privacy public chain, respectively responsible for decentralized transactions, smart contracts, and on-chain privacy protection. CETs that need to participate in complex financial contracts can be transferred to the Smart public chain through the DEX public chain, then moved back to the DEX public chain after that. CET tokens that need to participate in token confusion can also be carried out through the privacy transaction of the Privacy public chain, and can eventually be returned to the DEX public chain. The three public chains are responsible for their respective duties, and they are interconnected through the cross-chain technology through the relay mechanism. In addition to ensuring their respective transaction processing speed and functional attributes, they can also jointly provide richer and safer functions, and synergistically constitute the CoinEx decentralized public chain ecosystem. In addition, CoinEx Chain also supports any participant to issue new tokens on the chain and create new trading pairs for the issued tokens. CoinEx Chain guarantees the circulation of new tokens by establishing a trading pair between the new token and CET.
2.2 Component architecture
“ Tendermint Core and Cosmos SDK have improved the performance and operation capability of the blockchain. The SDK packaging reduces the consideration of non-related logic, hence reducing the development complexity. CoinEx Chain is based on Tendermint Core and Cosmos SDK, both of which have brought a big boost to the development of CoinEx public chain performance. Cosmos-SDK will implement the application logic of the blockchain. Together with the Tendermint consensus engine, it implements the three-layer architecture of the CoinEx public chain: the application layer, the consensus layer, and the network layer. Tendermint Tendermint is based on the state machine replication technology and is suitable for blockchain ledger storage. It is a list of transactions making consensus with Byzantine fault tolerance, the transactions are executed in the same order, and eventually the same state is obtained. Tendermint can be used to build various distributed applications. Cosmos SDK Cosmos-SDK is a blockchain framework that supports the construction of multiple assets with a consensus mechanism of POS (Proof of Stake) or POA (Proof of Authority). The goal of the Cosmos SDK is to allow developers to easily build custom blockchains from 0, while enabling the interaction with other blockchains. Cosmos-SDK is a blockchain framework that supports the construction of multiple assets with a consensus mechanism of POS (Proof of Stake) or POA (Proof of Authority). The goal of the Cosmos SDK is to allow developers to easily build custom blockchains from 0, while enabling the interaction with other blockchains. The blockchain development framework Cosmos SDK implements general functions such as account management, community governance, and staking in a modular form. Therefore, using the Cosmos SDK to build a public chain can simplify development procedures and facilitate operation. Tendermint is a fixed protocol in a partially synchronized environment, which can achieve throughput within a delay range of the network and each process itself. The CoinEx public chain is developed based on both, improving the performance and operability of the blockchain. The SDK packaging further reduces considerations of non-related logic and reduces the complexity of developers creating. The two components of Tendermint and Cosmos SDK are connected and interacted through the Application Blockchain Interface. Cosmos SDK and Tendermint interworking structure，Source:CoinEx; TokenInsight
2.3 Project public chain planning
The development plan of the CoinEx public chain is to create a series of public chains with specific application directions, including:
DEX public chain: solve the problems of lack of security and opacity that are widely criticized by centralized exchanges at present; aim to build a transparent, safe, and permission-free financial platform; restore the experience of central exchanges to the greatest extent；
Smart public chain: a public chain that specifically supports smart contracts and provides a platform for building complex financial applications;
Privacy public chain: mainly provides transaction amount, account balance, and information protection and the hiding of both parties to the transaction.
In order to achieve the performance of each specific application public chain, each public chain in the CoinEx public chain focuses on the development of a certain function. For example, in order to improve the transaction processing speed of the DEX public chain, the DEX public chain only supports the necessary functions and does not support smart contracts. To achieve the smart contract function support, cross-chain connection between the DEX public chain and the Smart public chain is required.
2.4 Operation analysis
“ The CoinEx platform publishes monthly ecosystem reports with high transparency; but the monthly reports are limited to contents about transactions and development, and lack progress in ecosystem and community construction, making them relatively simple. 2.4.1 Disclosure of ecosystem information Operational risks have a direct impact on platform users. Whether platform operations are smooth and whether there is transparency are issues that platform users care about. The CoinEx platform was established in 2017 and has around 3 years of development. It is also one of the platforms that has been developing for a long time in the exchange industry. It has obtained a digital currency trading license issued by the Estonian Financial Intelligence Unit (FIU), and the platform’s compliance is guaranteed to some degree. The actual operation of the CoinEx platform will be displayed in the form of ecosystem monthly reports. The monthly report contains various types of content such as online currencies, new activities, plans for the next month, and ecosystem dynamics. It involves multiple business dimensions including the CoinEx exchange, CoinEx Public Chain, and CET token. https://preview.redd.it/4mt0999ere551.png?width=631&format=png&auto=webp&s=cba27a7c90275f4c033bdd2445a72e6f294265e8 Snippet of a CoinEx ecosystem monthly report，Source: CoinEx; TokenInsight 2.4.2 Roadmap CoinEx Chain released its development roadmap for the four quarters of 2020 in January 2020. The roadmap shows that CoinEx Chain will undergo major updates on smart contracts and DEX hard fork upgrades. The project roadmap is basically planned on a monthly basis, with a clear plan and a clear direction of development. CoinEx Public Chain 2020 Development Roadmap，Source: CoinEx; TokenInsight In addition to the development route planned in the roadmap, CoinEx public chain also discloses its goals for next month in its monthly ecological report. The project’s main net was launched online in November 2019. According to TokenInsight’s review of the development of CoinEx public chain from January to April and the disclosure of the project’s ecosystem monthly report, the project’s plan about development of the smart contract Demo in February failed to be completed as planned; the project completed launching of the new version of the blockchain browser and the Asian Atlantis upgrade; the smart contract virtual machine development was planned to be completed in April, but the progress related to supporting cross-chain agreements was not disclosed yet. Overall, the project’s development route planning is clear, and the project’s development schedule is consistent with the plan, but there are still some discrepancies. Operation and development information is disclosed every month, and information transparency is high.
3. Industry & Competitors
The earliest origin of the exchange layout in the public chain field began in early 2018 when Binance released an announcement to start the development of the Binance Public Chain officially. In June of the same year, Huobi announced at its brand upgrade conference that it will combine the technical capabilities of the Huobi technical team and the community developers to develop the Huobi public chain called “Huobi Chain”. In December of the same year, OK Group announced the launch of its self-developed public chain OKchain, dedicating to provide underlying technical support and services for startups stationed in B-Labs. The successful launch of the public chain brings huge strategic significance to the exchange, which can not only improve the performance of the existing business of the exchange but also achieve further expansion of its influence. As one of the most important blockchain infrastructures, the public chain can benefit the exchanges behind it. As a platform for developing public chain technology exchanges, CoinEx’s main competitors in the field of public chain development include Binance, Huobi, and OKEx. Although they are all exchange platforms for deploying public chains, the above four are different in terms of specific functions, economic models, and critical points of the public chain.
3.1 Development progress comparison
In 2019, Binance became the first exchange to launch a public chain among all digital asset exchanges, and its main product is Binance exchange (DEX). In April 2020, Binance announced the launch of a second smart contract chain, using Ethereum’s virtual machine, so that developers can build decentralized applications without affecting the performance and functionality of their original chain. OKEx launched OKChain’s testnet in February 2020 and completed open source two months later. OKChain is designed as the basis of large-scale blockchain-driven business applications, with the characteristics of source code decentralization, point-to-point, irreversibility, and efficient autonomy. Huobi released Huobi Chain for the first time in July 2019, the code is open source, and the testnet was released in February 2020. As a “regulator-friendly financial blockchain”, Huobi Chain focuses on providing compliance services for companies and financial institutions. The CoinEx public chain officially completed the main online launch in November 2019 and completed the new block browser’s launch in March 2020. On April 3, 2020, CoinEx DEX uploaded the underlying code to Github to achieve open source. The CoinEx public chain is more inclined to build a full DEX ecosystem to achieve a one-stop solution for issuing, listing, storing, and trading. The long-term goal is to create a blockchain financial infrastructure.
3.2 Comparison of economic models
At present, the exchange is more inclined to use its existing platform currency as the native token of the public chain in the construction of public chain ecology. CoinEx’s CET, Binance’s BNB, and Huobi’s HT all fall into this category. OKEx is the only exchange that issues new tokens for its OKChain, which means OKT is the only ‘inflation token’ in the exchange’s public chain, while CET, HT, and BNB are all deflationary.
3.3 Decentralization of public chain
The initial number of CoinEx public chain verification nodes is 42, which is currently the most decentralized among all exchange public chains, and able to take both efficiency and decentralization into account; OKChain also currently has a relatively high degree of decentralization in the exchange public chain (21 verification nodes), its nodes have a high degree of autonomy; by contrast, Binance still firmly controls the operation of nodes and transactions; In terms of encourages cooperation between regulators and the private financial aspects, Huobi provides a lesser degree of decentralization. Huobi Chain uses a variant of the DPoS consensus algorithm to provide functions such as “supervision nodes”, allowing regulators to become validators.

4. Token Economy
CoinEx Token (CET) is a native token of the CoinEx ecosystem. It was issued in January 2018. Token holders can enjoy some user value-added services within the ecosystem. Currently, it is mainly used as a native token on the CoinEx Chain. As of 11 am on April 23, 2020, the current circulation of CET tokens in the market is 3,215,354,906.31, with a total of 5,842,177,609.53. CET tokens will not be further issued or inflated. Currently, daily repurchase and quarterly destruction are carried out. The repurchase destruction dynamics can now be tracked real-time on the CET repurchase system on the platform.
4.1 Token Distribution
The CET token used to be based on the ERC-20 token developed by Ethereum. Since the CoinEx Chain mainnet was launched in November 2019, some ERC-20 CET tokens have been mapped to the mainnet CET, and the rest of the CET will be mapped before November 10, 2020. CET holders need to deposit ERC-20 CET to the COinEX exchange, and the exchange will conduct the main network mapping. At present, CET is mainly circulated in the form of mainnet tokens, and only a small portion of ERC-20 CET has not been mapped. The distribution of token holdings currently circulating on the mainnet can be seen in the figure below. At present, the number of tokens held by the top ten holders accounts for about 60.44% of all mainnet CET tokens. Distribution of CET token holding addresses，Source: Etherscan; TokenInsight The following figure shows the initial distribution of tokens after the mainnet mapping preset by CoinEx. From the initial distribution map of CET, it shows that, after mapping, a large portion of CET remains concentrated in the hands of the team (31%), and the actual number of CET circulating in the market only accounts for 49% of the total. The initial distribution of CET token，Source: CoinEx; TokenInsight After the main net mapping, the 31% of the total CET (1.8 billion) held by the team will be gradually unlocked in the five years from 2020 to 2024, and 360 million CET will be unlocked each year. By 2024, the CET held by the team will be completely unlocked. From the current CET dynamics, the CET share held by some teams has been used for destruction purposes to achieve the purpose of CET austerity. If the frozen 1.8 billion CET held by the team are used for similar purposes, the development of CET and its platform can benefit from it. Team’s CET unlocking plan，Source: CoinEx; TokenInsight
4.2 Token economic model
4.2.1 Deflation mechanism Since the CET token went online in January 2018, CoinEx has increased the circulation of CET through airdrops, transaction fee refunds, operation promotion, and team unlocking. As one of the existing platform coins with long development time, the deflation mechanism of CET token has undergone a series of changes with the development of the industry. In 2018, when the concept of coin-based mining prevailed, CET used transaction mining, stake mining, and pending order mining, which were cancelled in October, December and, April respectively of the following year. The repurchase and destruction model currently used by CET was updated by CoinEx on April 11, 2020. The original CET quarterly repurchase and destruction policy of the platform will be adjusted to daily repurchase and quarterly destruction. After the implementation of the daily repurchase policy, CoinEx will take out 50% of the daily fee income for CET repurchase in the secondary market and implement quarterly destruction until the total remaining circulation is 3 billion (currently about 5.8 billion). At the same time that CoinEx updated the repurchase and destruction plan on April 11, the platform also launched a page dedicated to displaying CET repurchase information, so that users can clearly understand the progress of CET repurchase and destruction. As of April 23, 2020, the platform has destroyed 4,157,822,390.46 CET tokens, accounting for 41.6% of the initial total issuance. At the end of January 2019, it had destroyed 4 billion CETs (single destruction volume peak) at the end of this quarter. The number of CETs to be destroyed is 3,422,983.56. CET historical destruction data，Source: CoinEx; TokenInsight 4.2.2 Application scenarios The current usage scenarios of CET are discounted platform transaction fees, VIP services, special activities rights and interests, CoinEx Chain internal circulation fuel, and use of external scenarios. Deduction and discount of platform transaction fees CoinEx platform users can use CET to deduct transaction fees when conducting transactions within the platform. At the same time, using CET to pay transaction fees can enjoy the exclusive preferential rates provided by the platform. CET fee discount amount，Source：CoinEx; TokenInsight VIP service Holding a certain number of CETs can make a user become a platform VIP user. Users can also use CET to purchase platform VIPs to obtain corresponding privileges such as discounted rates, accelerated withdrawals, and exclusive customers. Special activity rights CET holders can enjoy special rights and interests in platform marketing activities, such as participating in the airdrop of tokens on the platform or accelerating opportunities for high-quality projects. CoinEx Chain built-in token CET will serve as a native token of CoinEx Chain, circulate and serve as fuel in CoinEx Chain, and users can also use CET to invest or trade other digital assets. In addition, CET can also serve as transaction fees and function fees (issuing Token, creating new trading pairs, account activation), etc. in the platform, and users can also participate in the campaign of validators by staking CET tokens. CET is currently used as a circulation token as well for CoinEx DEX to issue tokens, create orders, Bancor, address activation, set address aliases, and other application scenarios. In general, the types of application scenarios of CET are not plenty enough. In order to better develop the internal ecosystem of the platform, it is necessary to design and develop more CET usage scenarios and incentive mechanisms to increase the retention rate of users while adding new users. 4.2.3 Token incentive As the native token of the CoinEx public chain, CET will be used as a block incentive to increase community participation after the mainnet of the public chain launched. The 315 million CET held by the foundation in the total CET issuance will be used to incentivize initial verification nodes and Staking participants.

CoinEx’s investment is led by Bitmain and its main partners include Matrixport, Bitcoin.com, CoinBull, Consensus Lab, BTC.com, BTC.top, Hoo Exchange, Wa Yi, ChainFor.com, etc. Investment institutions and major partners have rich experience in the industry, which can promote the development of projects to a certain extent. However, the current industry involved by the partners is not wide enough, and it will have a limited role in promoting the future of CoinEx’s enriching business lines and increasing ecosystem functions. https://preview.redd.it/zjgzvv6ise551.png?width=533&format=png&auto=webp&s=a3f7fe3abb2c2d522e289213ae6fbc4e899825e0
6. Community Analysis
According to TokenInsight’s research of the CoinEx platform community, as of April 23, 2020, its official Twitter has 19,800 followers and 932 tweets; the official Telegram has 45 official groups, 3 in Chinese and English, and the other is Korean, Arabic, Vietnamese, Indian and other small language groups, with a total number of 56088 people; the current number of followers on Facebook accounts is 3,107. The overall community followers still have a lot of room for improvement, and community activeness needs to be improved. Number of followers on the CoinEx social platform，Source:TokenInsight At present, the project’s search popularity and official website visits are both top-notch, and monthly visits have slowly returned to their previous visit levels after experiencing a significant decline in December 2019.

"The Network Effect is King" - What I have learned after 3 years in crypto (Part 3)
This post is the third post of mine on things I've learned in the 3 years I have been in crypto. So far I have only posted them in the EthFinance daily since I didn't think they were worthy of dedicated posts but I have since figured I may as well post one here and see what you all think. Links to the first two posts are at the bottom. Here’s part 3 of my thoughts and what I have learned after 3 years in the crypto space. Enough with the embarrassing stories for now. Today I’m going to talk about one of the most fundamental rules in emerging technologies. It is very simple and goes as follows.
The network effect is king.
I cannot emphasise this enough. Coming into the crypto space I was already aware of the network effect. Just incase anyone here is unaware of the network effect, some dictionary app built into my MacBook defines the network effect as a phenomenon whereby a product or service gains additional value as more people use it. It’s why everyone uses Facebook Messenger or WhatsApp despite the incredibly invasive data tracking and despite the existence of private, secure, end to end encrypted alternatives such as Signal or Wire which are just as easy to use. Nobody wants to be “that guy” who makes their friends sign up to a new service just to stay in touch with each other (for the sake of helping people take online privacy more seriously, please be “that guy”, I will love you long time). The fact that you can join and have all of your friends already there in the app ready to interact with gives these platforms more value than other platforms which are fundamentally better. Unsurprisingly, crypto is no different. It’s why Bitcoin is still #1. The vast majority of people in crypto have a Bitcoin wallet and most people on the street have heard of Bitcoin even if they don’t know what it is. So if your store wants to accept Bitcoin or your website wants to accept donations, Bitcoin is the most obvious go to since most people will recognise the Bitcoin logo and anyone who owns crypto will almost certainly own some Bitcoin. However, if you display an ETH address, only those who truly delved deep into crypto and understand the advantages of Ethereum will have an Ethereum wallet. Just like how only the more privacy conscious individuals will have heard of or use Signal or Wire for messaging apps. Now here is where the network effect is important for us. As everyone in this sub should know, Ethereum is a turing complete ‘world computer’ whereas Bitcoin is strictly a payment network or digital store of value depending on who you ask. This clearly indicates that Ethereum’s potential market is much larger that Bitcoin’s since it can do what Bitcoin does and has dozens of other use cases like being a global settlement layer, tokenisation of digital and real world assets, insurance, supply chain tracking etc etc. The list goes on. Most importantly, in the field of this ‘world computer’ ultimate use case for blockchain which Ethereum is chasing after, Ethereum has by far the largest network effect.
At the time of writing this, Ethereum’s market cap ($26B) is more than 10x larger than its next largest competitor, EOS ($2.5B).
So what will it take for one of the many Ethereum killers to flip Ethereum? If you ask me, Ethereum’s head start is so large that even if the Ethereum ecosystem were to tear itself apart over a contentious hard fork I still wouldn’t be betting on a competitor to flip Ethereum’s largest fork unless we start to see some real adoption and infrastructure such as DeFi on these ETH killer chains. Ethereum being flipped seems about as plausible as Signal flipping WhatsApp. It’s pretty much a pipe dream. But what about Bitcoin then? Does this mean that Ethereum will never flip Bitcoin either? No, of course not. In fact, Ethereum has already flipped Bitcoin in terms of daily value transfer on the network thanks to stablecoins. As previously mentioned, Ethereum has a larger market to fill, so assuming the success of both Bitcoin and Ethereum, the flippening is almost inevitable. Like smart phones flipping basic mobile phones, it may take a while bit it will happen. It will take more time than many of us expected back in 2017. As mentioned at the beginning, this is part 3 of a series of posts I will be making. You can find part one and part two here.
Is All Cryptocurrency Mining Harmful to Our Environment?
https://preview.redd.it/bl0g74xrwm651.png?width=1400&format=png&auto=webp&s=13a69a7971ef9dc39dd3c571687331f77c6b52c1 Blockchain technology is now widely adopted in many fields, including banking, finance, administration, legal affairs, and investments. It can also be used for health and environment, and it shows its potential as it is utilized more and more worldwide. In the case of FLETA, we have developed a blockchain-based eCRF system, a clinical trial data collection tool, that helps people manage clinical trial data and contribute to the healthcare industry. However, at the same time, blockchain technology is blamed for its harmful influence on the environment. The reason for it is cryptocurrency mining. It is known that Bitcoin and many other cryptocurrencies are not entirely eco-friendly. The only way to create Bitcoins, since there is no central bank that issues the digital asset, is through miners. The miners solve cryptographic problems by using software specially designed for mining. Of course, energy is used when miners use the software to mine those cryptocurrencies. In the case of Bitcoin, only the fastest miner who solves the mathematical problem gets the mining reward, and miners compete to be the one. As the price of Bitcoin has increased, more people have participated in mining. This phenomenon caused severe competition among the miners, and the problems miners have to solve became much more complicated. As a result, miners need high-performance mining equipment that requires more energy than before to win the competition. Moreover, an increased number of miners and difficulty of problems also provoke a large amount of electricity consumption. Cryptocurrency miners are responsible for solving provided math problems, which is obtained using software specially designed to solve cryptographic problems. Of course, energy is used when miners use software for mining those cryptocurrencies. In the case of Bitcoin, only the fastest miner who solves the mathematical problem gets the mining reward, and miners compete to be the one. As the price of Bitcoin has increased, more people have participated in mining. This phenomenon caused severe competition among the miners, and the problems miners have to solve became much more complicated. As a result, miners need high-performance mining equipment that requires more energy than before to win the competition. Moreover, an increased number of miners and difficulty of problems also provoke a large amount of electricity consumption.
How much electricity is used for Bitcoin mining?
According to Digiconomist, it estimates that currently, the electricity expenditure in Bitcoin mining exceeds that of countries such as Denmark, Bulgaria, and Belarus, and accounts for more than 25% of Holland’s energy consumption, 15% of Australia or 10% of the United Kingdom. For example, according to the International Energy Agency (IEA), cryptocurrency is positioned as one of the businesses that consume the most electricity worldwide. If these cryptocurrencies were a country, they would be ranked 41st nation that consumes much power annually, according to Digiconomist.
So How Can We Use The Technology to Solve Our Problem?
As mentioned, cryptocurrency mining consumes a lot of energy, which inevitably harms the environment. Then, how can we prevent this problem from the blockchain industry? One of the solutions is choosing one of the many alternatives to the traditional Proof of Work consensus protocol. Proof of Stake, for instance, is far more eco-friendly since mining equipment is unnecessary.
How is FLETA Contributing to Saving the Planet
FLETA is a platform created for the deployment of decentralized applications. FLETA does not use a proof of work consensus algorithm as it has created its own. Proof of Formulation (PoF) is a new consensus model that replaces the traditional PoW. This new consensus protocol eliminates the possibility of unnecessary forks and allows blocks to be generated in a designated order. This consensus algorithm does not require a lot of electricity, similar to Proof of Stake that is eco-friendly. FLETA is not only infinitely scalable but also offers a high transaction processing speed using its original block design. The ability to infinitely scale is achieved through a multi sub-chain system. Whenever a DApp is created on top of FLETA, a new sub-chain is also deployed, which means that every single dApp can be operated independently and without affecting other DApps.
FLETA also has created an eco-friendly consensus algorithm Proof of Formulation that allows the platform to be more scalable and efficient. Developers can easily build their DApps on top of FLETA and enjoy all the benefits of the platform like higher transaction speed, scalability, and being able to operate independently.
https://preview.redd.it/jcgmn1wf4o251.png?width=1400&format=png&auto=webp&s=55aa66f3a02fb3aefbbd2cc0fec1468645ab24cd What is double-spending? To understand what double-spending means, we must first understand how a blockchain network works. All cryptocurrencies use what is known as a blockchain. It is essentially a chain of blocks where each block is made up of digital information about transactions. Bitcoin and other cryptocurrencies cannot be forged because the blockchain is public and immutable. Because of a consensus algorithm each chain has, it is almost impossible for someone to form a transaction or block. Picture this, James sends Kate 4 Bitcoin. This transaction is made public, and everyone receives information about it. Also, the transaction has to be verified. If James doesn’t have 4 Bitcoin, the verification will fail, and Kate will not receive any Bitcoin. The verification process happens through the consensus algorithm.
Can Double-Spending Really Happen?
Double-spending happens when an attacker spends the same funds twice. For example, if James sends 4 Bitcoin to Kate and also to Alex at the same time, only one of the transactions will be confirmed. This problem is easier to solve on centralized systems; if there is a central institute like a bank, it can take charge of the problem. However, since blockchain is decentralized, there is no specific one responsible for the double-spending attack. Even though the consensus algorithm partly prevents double-spending, unfortunately, this cannot be the final solution as the problem can still occur. Theoretically, if someone were able to hold more than 50% of the mining power available, he or she would have the ability to overturn network transactions and may make double-spending valid. Although this might seem unlikely, it can happen for real. In 2014, the mining pool Ghash.io obtained 51% of Bitcoin’s hashing power but capped their power at 39.99% to increase the trust in the network. However, this event raised significant concerns about the safety of the network, as most mining power seems to be in control of a few parties only. Other cryptocurrencies have suffered 51% attacks, Bitcoin Gold, for example, was hit by a 51% attack in 2018 and just recently in 2020.
The Final Solution for Double-Spending, FLETA
FLETA is a blockchain-based platform for the creation of decentralized applications. FLETA employes an innovative sharding model where each shard operates individually and independently. Each DApp on the FLETA network operates independently and doesn’t rely on other DApps as it has its own sub-chain. Because each chain operates independently in a parallel structure, data is not shared between the chains, and chains are not affected by each other. For this reason, double spending is not feasible and provides a high transaction speed. Also, FLETA’s consensus algorithm, PoF(Proof-of-Formulation), prevents the double-spending problem. Its mining node, Observer Node, confirms a generated block real-time, and confirmation of 3 out of 5 observer nodes is necessary. This system eliminates the possibility of double-spending.
Although the initial consensus mechanism works, it is not entirely secure against double-spending attacks. A 51% attack has been shown to be achievable even in cryptocurrencies. FLETA has been able to create an innovative sharding model that allows each chain to operate independently. Moreover, its PoF consensus algorithm confirms a block systematically in real-time. Thanks to them, FLETA is free from the double-spending issue.
I’ve been losing sleep. I don’t think I’m particularly special in that regard, I think everyone has been losing sleep these days. A global pandemic tends to do that to people. Yet the thing that has been keeping me awake isn’t the virus. I’ve been losing sleep over an old couch I once crossed paths with. It’s been eight years, I want to believe that I’ve put the past behind me, but being locked in a house for a couple of weeks has made it impossible to not dwell on the past. The memory of the couch started off as a fleeting thought over my morning coffee, but as days have turned into weeks that memory has grown into a distinct vision of madness. What I saw during those three drunken nights in December of 2012 has become an unavoidable part of reality. I can’t rest until I process it. So since we have a nice little Internet campfire going here I figured I would tell you guys a story. Hopefully it will let me put this whole part of my past to rest and maybe it will take your mind off of what is happening outside. So kick back and let me tell you a tale of love and loss, of broken teenage hearts, of surviving in a crumbling world. Let me tell you a story about the couch that tried to seduce me. I was nineteen, hung-over and heartbroken. I was also stuck in a foreign country. Well, to call Estonia a foreign country would be a bit of a long shot, I had lived there for a good five years of my life. It was in Estonia that I lived out most of my teenage years. This was where I had smoked my first cigarette, had my first drink, fell in love for the first time. I was dragged in when I was thirteen by my parents; they had business in Tallinn and wherever they went I went. At eighteen, when my parent’s contracts ran out, I was forced back home. Their business with Estonia was done. Mine was not. By nineteen I was back. As soon as I got off the plane I turned my phone on and checked my messages. She didn’t write to me. My soul, positioned somewhere slightly above my abdomen, twitched in discomfort. It was a familiar twitch, I had felt it in the bus to the airport, I had felt it in the security check, I had felt it when I boarded the flight to Tallinn and as soon as I got off the plane the twitch was back with a vengeance. The discomfort I was feeling in my chest was a realization. It was the realization that I had emptied out most of my already slim bank account on a one-way ticket halfway across the continent to see my old high-school sweetheart who wasn’t interested in seeing me. It was the realization that as much as I consciously knew the trip was a bad idea, I couldn’t resist going. I dragged my feet towards the arrivals hall. When it became obvious that Saale was dodging my messages I panicked. There was no place for me to crash, I had no money for a flight, hell, I had no money for food. As I boarded the plane to Estonia I sent off a panicked text message to my old band-mate: ‘Made horrible mistake. Landing in Tallinn in three hours. Can I crash at yours?’ Within two minutes there was a reply: ‘OK. Will come with Maarja. See you soon.’ Karl wasn’t very chatty, but he was always there when needed. The two of them were waiting for me as soon as I walked out into the arrival hall. They barely changed. Karl was still a giant of man. His long hair had gotten longer and the beard he had rocked since seventeen had gotten thicker, the guy looked like Jesus on steroids if Jesus was really into heavy metal and wore glasses. Next to Karl stood Maarja, she wore a garish yellow coat. The pink streak in her hair she’d been so proud of back in middle school was pinker than ever. “JAAMEEES! YOU’RE BACK!” Maarja yelled in her high-pitched faux-English accent before nearly tackling me to the ground. “It’s been too long honey! Too long!” She hadn’t changed a bit since I left the country. Maarja was still a pint-sized bolt of energy. The two of them made for an odd couple. “Welcome back, Friend,” Karl said after Maarja was done squeezing me. He wasn’t one for physical contact, Karl settled on a simple pat on the shoulder that challenged my entire skeletal structure. The three of us made our way outside to catch a bus to the center. Even after living in Estonia for five years I still wasn’t used to the winters. As soon as we walked out into the sub-zero temperature I felt decidedly like a foreigner. We caught up on the small things while we waited for the bus. Karl and Maarja had officially moved in together, the band that Karl and me started up in high-school had broken up, Maarja was in the process of getting a bachelors degree of psychology and Karl was really into some crypto-currency stuff that went completely over my head. I couldn’t get much out of me; the cold was taking a real toll on my system. Whenever I opened my mouth to talk about my miserable little life I simply ended up chattering my teeth. As soon as we got on the bus I threw myself at the nearest heating vent. “So, James,” Maarja said as soon as we got on the bus, “You still talk to Saale?” When I turned away from the heater to face her she froze, “I mean, we don’t have to talk about, forget I asked.” “Do I look that bad?” While Maarja searched for a diplomatic answer Karl stepped in with his special brand of honesty, “You look very tired and unhappy.” “Well, I am happy to see you guys and I am excited to be here, but, yeah,” I decided to get the conversation out of the way, “We tried two months of long-distance, but Skype only gets you so far. Broke up in late July. After we split we agreed to not talk for a couple of months, to give each other some time to clear the system and all that. Keeping radio silence was hard at first but after a couple of weeks I started to get used to it. I was learning to live without her. Things were starting to straighten up, I even took a stab at dating but when the holidays rolled around the loneliness came back. On Christmas I figured I’d throw Saale a holiday message. She wrote back. We started chatting on a daily basis.” The bus bounced through my old neighborhood. Memories of my drunken youth jumped at me from every corner, most of those memories involved Saale. “Last night we got pretty drunk,” I continued, “Things got flirty. We started talking about what we would do if we weren’t half a continent away from each other. She mentioned her parents were out of town until the end of January on some sort of an anniversary trip. I offered to fly in. She told me I should. Now I’m here.” “She changed her mind?” Karl asked. “She didn’t think I was serious about flying over. Didn’t exactly check with her before I bought the ticket. She flipped out when I got it, told me to get a refund and then hung up on me when I insisted on meeting up. She hasn’t answered any of my messages since.” A part of me felt good to get the story out of my system but saying it out loud just added to the absurdity. I could have not bought the ticket, I could have gotten a refund, I could have not gotten on that plane. Everything could have been avoided, but nineteen year old me leaped at the opportunity for a grand romantic gesture like a hungry animal. “Very strange,” Karl finally said after considering my story. He shot a look over to Maarja, as if she was the ambassador to all women-kind, “Very strange, right?” Maarja shrugged. Maarja’s house was the crown jewel of my high-school social life. It was a three-apartment unit that was built at some point before the world wars. This place was old, as you would walk around the little apartment it would creak, but it made for a perfect party place. Maarja had inherited the apartment from her grandma at sixteen; the Estonians saw child rearing as a fairly independent process. If she couldn’t survive on her own at sixteen she probably couldn’t make it at thirty, a bit of responsibility would prepare her for the frigid world outside. Maarja used her newly found independence to throw the biggest house parties that the neighborhood had ever seen. Maarja’s place was perfect for booze filled gatherings. It was spacious enough to hold any drinking game we could dream up, there was a nice terrace for smoking and the neighbors were either deaf, completely apathetic about teenage drinking or both. As soon as the front door opened I was assaulted by memories. Visions of drunken nights on the floor of the living room, of hung-over mornings of the kitchen; the old apartment breathed with the past. For a split second a wave of gratitude for a youth well spent washed over me, but then I remembered that each of those fond memories had an element I wanted to block out. Most of the fun I had in the apartment had been with Saale by my side. Maarja and Karl still slept on an old mattress on the floor, the walls were still covered with cut outs of boy-bands that Maarja had stuck to the wall in her tweens. The only thing that changed about their bedroom was the addition of a massive computer rig on the table. There were strange ventilators and cooling tubes and blinking lights, the machine looked like something straight out of a sci-fi flick. “That’s my mining rig,” Karl said proudly. I nodded as if I understood what he was talking about. “Where are the rats?” I asked, noticing the empty cage on Maarja’s wardrobe. Back in the day Maarja had two rats, Fritz and The Duchess. She would keep them in the cage most of the time, but whenever the night reached a certain point of drunkenness Maarja would sneak over to her bedroom and come out with the two animals. If you saw Maarja with two rats running up and down her body you knew the night was really going to become a rager. “The Duchess died last week,” Maarja said with a glint of sorrow, “Fritz wasn’t taking it well. Think the little guy was depressed being in the cage all alone, so I’m letting him roam around the house for the time being. Hopefully a bit of freedom will cheer him up.” As if he had heard his name, Fritz peeked out from behind the wardrobe. The albino rat raised his snout in the air, sniffed for a bit and then lumbered off to the living room. The years had taken their toll on Fritz, he no longer moved with the youthful energy I was used to, but the one part of him that I remembered had not changed. Fritz still had balls that were disproportionately giant to his body. As he moved away from us he dragged them behind him with Sisyphean effort. “So, which hostel are you crashing at?” Maarja asked. A lump manifested in my throat. I looked around the cramped apartment. Outside of the mattress there was nowhere for me to sleep. I didn’t have any money for a hostel. “Ah, I’m just kidding. You’re crashing here. We owe you anyway,” Maarja said with good cheer. “For what?” I asked, relieved that I wasn’t homeless. “Financing the booze and cigarettes back in the day, might have ended up a nun if it weren’t for you,” she said with a grin. It was true, throughout high school I had been the main financier of our misadventures, my parents had foreign money and that money went pretty far by Estonian standards. More importantly though; when everyone was sixteen I looked twelve. According to the law of teen streets, the late bloomer provides the dough for those who can buy stuff without ID. “You’ll sleep on the couch, we just haven’t had the time to get it out of the garage. How about you and Karl drag it in while I make some tea?” Even though it was a bright winter day outside the garage was in near darkness. The only thing that illuminated the cramped musty room was a single ray of light shining in through a cracked skylight. The garage was covered in flimsy shelves that buckled beneath the weight of greasy machine parts. In the center of the garage lay a couch shaped object covered with a large, stained cloth. Karl grabbed ahold the cloth and was about to pull it away, but a thought struck him. “James, if I tell you something will you not tell Maarja?” He asked, letting the cloth drop back down to the floor. He looked straight at me; his small eyes were probing me for trustworthiness. “Well, depends on what it is,” I said, “Don’t need help burying a body, right?” “No,” Karl’s intensity broke into a smile, “It is nothing illegal. Just a secret.” He strode towards one of the rickety shelves and plunged his hand deep into its depths. After a moment of rustling he pulled out a small box. He opened it. Even though the garage was dark, and even though the diamond was tiny, you could see a little glimmer. Karl’s eyes shone twice as bright. “Wow man,” I said, realizing how quickly the world was moving on, “Congratulations!” Maarja and Karl would get married and I would be at their wedding alone. As I stood in that garage the thought that I would always be alone gushed dread through my veins. We used to joke about how Saale and me would get hitched before the two of them did. Those jokes felt cruel now. Maarja and Karl would get married and one day Saale would get married too. She would get married to someone who wasn’t me. “I’m really happy for you.” “I want to ask her father soon. He does not like me much, but I think I can show him that I can provide for his daughter. This Bitcoin thing will be big soon James, in a couple of years me and Maarja will be rich.” Karl put the box back into its hiding place. “Promise not to tell her, yes?” “Promise,” I said with as much candor as I could muster, but my mind was elsewhere. My mind was floating disembodied in a bright church, watching my would-be-wife get married to someone else. “James,” Karl’s paw on my shoulder brought me back into reality, “You will be okay. I know you are worried about Saale, but you still have us. We will drink this away.” He smiled. I tried to smile back. “Let’s get this couch, shall we?” He pulled away at the cloth that covered the couch. Enough dust flew off into the air to send us both into a coughing fit. The room danced with dirty particles. Yet from behind the veil of powder I could see it. I could see the couch. The thing was ancient, a couch straight out of the early days of the Soviet Union. Its flowery upholstery was covered in stains that just screamed history. It was as if the piece of furniture had been used for barricades in the defense of Stalingrad and lived to talk about it. Filth filled its rumpled cloth, it stood on firm wooden legs that seemed to have survived multiple generations of being clawed at, it was as if the thing was simply biding its time until its true masters came back to retrieve it. The couch was old, but somehow in that dark garage, in that gust of earthly smoke, there was something alluring about it. It looked ratty but comfortable, even inviting. For a split second I was sure that the couch had winked at me with its cushioning. Then the dust settled and it was just a piece of furniture. Karl grabbed one side of the couch, I grabbed the other and we started to haul the thing towards the living room. We had left the garage, but there was still tension in the air. I was still thinking about Saale getting married to someone who wasn’t me. It was still as if Karl and me were meant to have a serious discussion. Neither of us were comfortable. “I lost my virginity on this couch,” I shared, hoping to relax the situation. Karl grinned, accepting the levity, “Gross.” We dragged the couch to the living room and then joined Maarja in the kitchen. Back in the day her kitchen table was the go-to place to gather before drinking and after drinking. We would sit around and shoot the shit and wait for someone to drop off the booze for the evening or the hung-over pizza for the morning. Yet as we sat there, trying to make small talk, one of the chairs was empty and it made all the difference. I couldn’t focus on anything that was being said around me, all I could think about was how Saale used to sit next to me. All I could think about were her long legs on my lap, her long fiery hair, her laughter. “How about we sweeten the evening with a bit of moonshine?” Maarja asked, as she fished a clear bottle out of the kitchen counter, “Karl and me are going to lunch with my parents tomorrow though, so no hangovers.” Karl cheered on the promise of alcohol, but not even drink could lift my spirits. My eyes shifted from Saale’s empty seat to the couch. All I wanted to do was lie down and fall asleep for a thousand years. “Guys, I appreciate the hospitality but I’m really tired. How about we drink tomorrow?” I said. Karl and Maarja looked concerned, this was the first time they had ever seen me refuse booze. “Are you sure you’re okay honey? We can talk about it if you want to,” Maarja suggested. I insisted I was fine; I just needed to get some rest. That didn’t convince her, but she yielded, “Well, we’ll be in my room if you need us.” Her and Karl shuffled off to her bedroom. I laid down on the couch. From the other room I could hear them talk. Maarja talked in concerned whispers whilst Karl spoke at full volume, it didn’t make much of a difference, even after five years of being in the country I still couldn’t understand Estonian. I could hear my name being mentioned though. They were concerned about the emotional wreck that was crashing on their couch. I dragged my friends into my mess. It was all so humiliating; I was far from home, broke and broken. I wanted to die. ‘Easy there Tiger, don’t think like that,’ a faint voice emerged from the back of my head, ‘Things might not seem great right now, but look on the bright side, at least you’re on a comfortable couch.’ The voice was right; the couch was indeed comfortable. ‘All you need is a bit of a distraction to forget about your broken heart. Some booze, some dope, maybe a bit of love and you’ll be good as new.’ It was as if the suave voice turned a switch in my mind. Suddenly the tightness in my chest eased, a burst of joy started to bubble in my abdomen. My fingers started to trace the sides of the upholstery. The voice giggled, ‘That’s the spirit Tiger, just relax, you’re fine as long as you’re here with me.’ The universe felt lighter, my feelings of dread faded away and were replaced with an electric anticipation. I needed a drink to celebrate. I opened the door to Maarja’s bedroom. She was lounging on the mattress reading a psych textbook. Karl was watching bar graphs on the computer. “Hey guys,” I peeked in, “I feel a bit better now, how about those drinks?” They both grinned. We drank. In the moment I didn’t give much thought to the voice in my head, my internal monologue was turned up a notch since the break-up anyway. I was used to hearing thoughts that I consciously didn’t want to consider; the silky voice that was telling me that things would be okay was a welcome distraction. I sunk into the couch and I let the night carry me away. ‘See Tiger? Isn’t it nice to be here? Isn’t life just swell on this little old couch?’ it would say. I nodded along. We drank more. All thoughts of avoiding hangovers were let go; the liquor poured freely. At some point Maarja emerged out of her room with Fritz on her shoulder. We celebrated the tradition of our youth but the rat was sluggish, far too old to crawl around on her body. After a couple of minutes Maarja gave up on playing with the rat. She put him on the ground. Fritz simply walked around the room dragging his testacles behind him like a ball and chain. We drank more. Karl lumbered up to his feet and went to fetch his guitar. Maarja was out having a cigarette. I was far too comfortable on the couch. Having a moment to myself I watched the rat. Fritz had spent the past couple of minutes roaming the living room and sniffing at my backpack. Yet suddenly something caught his attention, he sniffed at the air, his whiskers bouncing in curiosity. Then he looked towards the couch. The old rat sprung to his hind legs and turned towards me. It was as if his beady eyes were locked to the piece of furniture. ‘Oh Tiger, don’t think about the stupid rat. Look, here comes Karl, let’s stop thinking about stupid things and listen to him play.’ Oh and how he could play. To say that Karl lacked warmth would be an understatement, communicating with the guy often felt like having a conversation with a pile of awkwardly stacked encyclopedias, but as soon as he would bring out the guitar he would ooze personality. Somehow, with those hulking fingers of his, Karl had managed to make the strings sing the gentlest of tones. Maarja and me sang along out of key as the night went on. ‘Just like the good old days, Tiger, you’re here and you’re happy. Focus on the positives, focus on the present,’ the voice told me. I followed the advice, until I couldn’t. It was as if a spell had been broken. As soon as I heard those opening chords, as soon as I realized what Karl was playing my stomach sank. It was that Rolling Stones song. Saale and me had danced to it once upon a time. Memories of our first night together came rushing into my mind. The Saale shaped hole in my heart throbbed with pain. I got up to splash some water on my face. Karl shifted his performance into a serenade for Maarja. The tiles in the bathroom were freezing but I was willing to withstand the pain if it meant I could get further away from the song. I stood there, willing to wait it out, but the memories just kept on floating back. I was standing in the same bathroom I stood in the night that I met Saale. I could see traces of a sixteen-year old in my face. The music kept on building. Saale’s lily perfume filled my nostrils. I could remember the fullness of her lips before our first kiss. The images were cascading on top of each other, ripping away at my sanity, ready to plunge me into a panic attack. But then they stopped. The music stopped. I peeked out of the door. Karl had chucked his guitar over to the side. His serenade had given way to a heavy make out session. Him and Maarja were all over each other. “Guys, I’m going to go out for a cigarette,” I announced. The two of them looked up at me dazed and drunk. “Take the keys honey, I think we’re going to bed.” I hoped that the dial tone would block out Maarja’s moans but it didn’t. Not only did I have to listen to a loving couple have sex, I also had to listen to world’s quietest dial tone as I was reminded that Saale did not want to talk to me. I stood out there in the freezing cold smoking one cigarette after another. It was just me, the starless sky and Maarja’s moans. Karl lasted for a quarter a pack before their bedroom quieted down. I tried calling Saale one more time and then went back inside. By the time I stumbled to the couch I could already hear snoring coming from the bedroom. But there was another sound in the apartment, something much quieter, something I almost didn’t notice. Scratching. Luckily I managed to prop myself up against the couch before I sat on him. As I tried to regain my balance I realized just how drunk I was. Fritz was on the couch, furiously scratching into its upholstery. He looked up at the drunken figure hovering over him for a split second and then went back to work. Those little claws scratched with the ferocity of a pup. It was as if Fritz was two years younger. I picked him up by his scruff and tried taking him off the couch. When I lifted him off the ground the rat seemed confused for just a split second before- ‘Aiiieee’ Fritz screamed the world’s tiniest scream and then bit me in the finger. He dropped to the ground and ran beneath a nearby wardrobe. He hid beneath it and watched me. I was too drunk and tired to care. I laid down on the couch and exhaled. ‘Welcome back Tiger, you look tired. Let me keep you company. Yes, life is hard, but if you really appreciate the moment it can be pretty enjoyable. Lie down here, let me keep you hold you. Let’s get to know each other better.’ I could smell floral perfume. I closed my eyes and drifted off to a deep sleep. (Next part)
The Intellectual Foundation of Bitcoin比特幣的智識基礎. By Chapman Chen, HKBNews

For instance, The 1776 First Amendment separates church and state, and contemporary American liberation psychologist Nozomi Hayase (2020) argues that money and state should similarly be separated. Just as Isaac Newton’s study of alchemy gave rise to the international gold standard, so has the anonymous creator Satoshi Nakamoto's desire for a “modernized gold standard” given rise to Bitcoin. Indeed, Bloomberg's 2020 report confirms Bitcoin to be gold 2.0. Montesquieu (1774) asserted that laws that secure inalienable rights can only be found in Nature, and the natural laws employed in Bitcoin include its consensus algorithm and the three natural laws of economics (self-interest, competition, and supply and demand). J.S. Mill (1859) preferred free markets to those controlled by governments. Ludwig von Mises (1951) argued against the hazards of fiat currency, urging for a return to the gold standard. Friedrich Hayek (1984) suggested people to invent a sly way to take money back from the hands of the government. Milton Friedman (1994) called for FED to be replaced by an automatic system and predicted the coming of a reliable e-cash. James Buchanan (1988) advocated a monetary constitution to constrain the governmental power of money creation. Tim May (1997) the cypherpunk proclaimed that restricting digital cash impinges on free speech, and envisioned a stateless digital form of money that is uncensorable. The Tofflers (2006) pictured a non-monetary economy. In 2016, UCLA Professor of Finance Bhagwan Chowdhry even nominated Satoshi for a Nobel Prize. Full Text: Separation between money and state The 1791 First Amendment to the U.S. Constitution enshrines free speech and separates church and state, but not money and state. "Under the First Amendment, individuals’ right to create, choose their own money and transact freely was not recognized as a part of freedom of expression that needs to be protected," Japanese-American liberation psychologist Nozomi Hayase (2020) points out (1). The government, banks and corporations collude together to encroach upon people's liberties by metamorphosing their inalienable rights into a permissioned from of legal rights. Fiat currencies function as a medium of manipulation, indulging big business to generate market monopolies. "Freedom of expression has become further stifled through economic censorship and financial blockage enacted by payment processing companies like Visa and MasterCard," to borrow Hayase's (2020) words. Satoshi is a Modern Newton Although most famous for discovering the law of gravity, Isaac Newton was also a practising alchemist. He never managed to turn lead into gold, but he did find a way to transmute silver into gold. In 1717, Newton announced in a report that, based on his studies, one gold guinea coin weighed 21 shillings. Just as Isaac Newton’s study of alchemy gave rise to the international gold standard, so has the desire for a “modernized gold standard” given rise to Bitcoin. "In a way, Satoshi is a modern Newton. They both believed trust is best placed in the unchangeable facets of our economy. Beneath this belief is the assumption that each individual is their own best master," as put by Jon Creasy (2019) (2). J.S. Mill: free markets preferable to those controlled by governments John Stuart Mill (1806-1873) the great English philosopher would be a Bitcoiner were he still around today. In On Liberty (1859), Mill concludes that free markets are preferable to those controlled by governments. He argues that economies function best when left to their own devices. Therefore, government intervention, though theoretically permissible, would be counterproductive. Bitcoin is precisely decentralized or uncontrolled by the government, unconfiscatable, permissonless, and disinflationary. Bitcoin regulates itself spontaneously via the ordinary operations of the system. "Rules are enforced without applying any external pressure," in Hayase's (2020) words. Ludwig von Mises (1958): Liberty is always Freedom from the Government In The Free Market and its Enemies, theoretical Austrian School economist Ludwig von Mises (1951) argues against the hazards of fiat currency, urging for a return to the gold standard. “A fiat money system cannot go on forever and must one day come to an end,” Von Mises states. The solution is a return to the gold standard, "the only standard which makes the determination of the purchasing power of money independent of the changing ideas of political parties, governments, and pressure groups" under present conditions. Interestingly, this is also one of the key structural attributes of Bitcoin, the world’s first, global, peer-to-peer, decentralized value transfer network. Actually, Bloomberg's 2020 report on Bitcoin confirms that it is gold 2.0. (3) Von Mises prefers the price of gold to be determined according to the contemporaneous market conditions. The bitcoin price is, of course, determined across the various global online exchanges, in real-time. There is no central authority setting a spot price for gold after the which the market value is settled on among the traders during the day. Hayek: Monopoly on Currency should End Austrian-British Nobel laureate Friedrich Hayek’s theory in his 1976 work, Denationalization of Money, was that not only would the currency monopoly be taken away from the government, but that the monopoly on currency itself should end with multiple alternative currencies competing for acceptance by consumers, in order "to prevent the bouts of acute inflation and deflation which have played the world for the past 60 years." He forcefully argues that if there is no free competition between different currencies within any nation, then there will be no free market. Bitcoin is, again, decentralized, and many other cryptocurrencies have tried to compete with it, though in vain. In a recently rediscovered video clip from 1984, Hayek actually suggested people to invent a cunning way to take money out of the hands of the government:- “I don’t believe we shall ever have a good money again before we take the thing out of the hands of government, that is, we can’t take them violently out of the hands of government, all we can do is by some sly roundabout way introduce something they can’t stop” (4). Reviewing those words 36 years hence and it is difficult not to interpret them in the light of Bitcoin. Milton Friedman Called for FED to be Replaced by an Automatic System Nobel laureate economist Milton Friedman (1994) was critical of the Federal Reserve due to its poor performance and felt it should be abolished (5). Friedman (1999) believed that the Federal Reserve System should ultimately be replaced with a computer program, which makes us think of the computer code governing Bitcoin (6).[\](https://en.wikipedia.org/wiki/Criticism_of_the_Federal_Reserve#cite_note-:2-12) He (1970) favored a system that would automatically buy and sell securities in response to changes in the money supply. This, he argued, would put a lid on inflation, setting spending and investment decisions on a surer footing (7). Bitcoin is exactly disflationary as its maximum possible supply is 21 million and its block reward or production rate is halved every four years. Friedman passed away before the coming of bitcoin, but he lived long enough to see the Internet’s spectacular rise throughout the 1990s. “I think that the Internet is going to be one of the major forces for reducing the role of government," said Friedman in a 1999 interview with NTU/F. On the same occasion, he sort of predicted the emergence of Bitcoin, "The one thing that’s missing, but that will soon be developed, is a reliable e-cash, a method whereby on the Internet you can transfer funds from A to B, without A knowing B or B knowing A." (8) “Of course, Friedman didn’t predict the block chain,” summed up American libertarian economist Jeffery Tucker (2014). “But he was hoping for a trustless system. He saw the need.” (9). Bitcoin Computer Code as Constitution in the Buchananian Sense American economist cum Nobel laureate James Buchanan (1988) advocates constitutional constraints on the governmental power to create money (10). Buchanan distinguishes a managed monetary system—a system “that embodies the instrumental use of price-level predictability as a norm of policy”—from an automatic monetary system, “which does not, at any stage, involve the absolute price level” (Buchanan 1962, 164–65). Leaning toward the latter, Buchanan argues that automatic systems are characterized by an organization “of the institutions of private decision-making in such a way that the desired monetary predictability will emerge spontaneously from the ordinary operations of the system” (Buchanan 1962, 164). Again, "Bitcoin regulates itself through the spontaneous force of nature, flourishing healthy price discovery and competition in the best interest of everyone" (Hayase 2020). Shruti Rajagopalan (2018) argues that the computer code governing how the sundry nodes/computers within the Bitcoin network interact with one another is a kind of monetary constitution in the Buchananian sense. One of Buchanan's greatest inputs is to differentiate the choice of rules from the choice within rule (Buchanan 1990). One may regard the Bitcoin code as a sort of constitution and "the Bitcoin network engaging in both the choice of rules and choice within rules" (Rajagopalan 2018) (11). Tim May: Restricting Digital Cash may Impinge on Free Speech Cypherpunks are activists who since the 1980s have advocated global use of strong cryptography and privacy-enhancing technologies as a route to social and political liberation. Tim May (Timothy C. May [1951-2018]), one of the influential cypherpunks published The Crypto Anarchist Manifesto in September 1992, which foretold the coming of Bitcoin (12). Cypherpunks began envisioning a stateless digital form of money that cannot be censored and their collaborative pursuit created a movement akin to the 18th Enlightenment. At The 7th Conference on Computers, Freedom, and Privacy, Burlingame, CA. in 1997, Tim May equated money with speech, and argued that restricting digital cash may impinge on free speech, for spending money is often a matter of communicating orders to others, to transfer funds, to release funds, etc. In fact, most financial instruments are contracts or orders, instead of physical specie or banknotes (13). Montesquieu: Laws that secure inalienable rightscan only be found in Nature In his influential work The Spirit of Laws (1748), Montesquieu wrote, “Laws ... are derived from the nature of things … Law, like mathematics, has its objective structure, which no arbitrary whim can alter". Similarly, once a block is added to the end of the Bitcoin blockchain, it is almost impossible to go back and alter the contents of the block, unless every single block after it on the blockchain is altered, too. Cypherpunks knew that whereas alienable rights that are bestowed by law can be deprived by legislation, inalienable rights are not to be created but can be discovered by reason. Thus, laws that secure inalienable rights cannot be created by humankind but can be found in nature. The natural laws employed in Bitcoin to enshrine the inalienable monetary right of every human being include its consensus algorithm, and the three natural laws of economics (self-interest, competition, and supply and demand) as identified by Adam Smith, father of modern economics. Regarding mathematics, bitcoin mining is performed by high-powered computers that solve complex computational math problems. When computers solve these complex math problems on the Bitcoin network, they produce new bitcoin. And by solving computational math problems, bitcoin miners make the Bitcoin payment network trustworthy and secure, by verifying its transaction information. Regarding economic laws, in accordance with the principle of game theory to generate fairness, miners take part in an open competition. Lining up self-interests of all in a network, with a vigilant balance of risk and rewards, rules are put in force sans the application of any exterior pressure. "Bitcoin regulates itself through the spontaneous force of nature, flourishing healthy price discovery and competition in the best interest of everyone," to borrow the words of Hayase (2020). A Non-monetary Economy as Visualized by the Tofflers In their book, Revolutionary Wealth (2006), futurists Alvin Toffler and his wife Heidi Toffler toy with the concept of a world sans money, raising a third kind of economic transaction that is neither one-on-one barter nor monetary exchange. In the end, they settle on the idea that the newer non-monetary economy will exist shoulder-to-shoulder with the monetary sector in the short term, although the latter may eventually be eclipsed by the former in the long run. What both the Tofflers' The Third Wave (1980) and Revolutionary Wealth bring into question is the very premise of monetary exchange. The vacuum left over by cash in such a non-monetary economy may be filled up by Bitcoin as a cryptocurrency. Satoshi Nakamoto Nominated for Nobel Prize by UCLA Finance Prof. UCLA Anderson School Professor of Finance Bhagwan Chowdhry nominated Satoshi Nakamoto for the 2016 Nobel Prize in Economics on the following grounds:- It is secure, relying on almost unbreakable cryptographic code, can be divided into millions of smaller sub-units, and can be transferred securely and nearly instantaneously from one person to any other person in the world with access to internet bypassing governments, central banks and financial intermediaries such as Visa, Mastercard, Paypal or commercial banks eliminating time delays and transactions costs.... Satoshi Nakamoto’s Bitcoin Protocol has spawned exciting innovations in the FinTech space by showing how many financial contracts — not just currencies — can be digitized, securely verified and stored, and transferred instantaneously from one party to another (14).

Both of these are actually under test and contained in a forked Bitcoin client called Bitcoin Ultimate. There is also an interesting whitepaper proposal called sub-chains. Again the idea is to Bitcoin’s intense consolidation phase may soon draw to a close, as multiple technical patterns are now suggesting that some massive volatility is The new blockchain will work with the use of sub chains, explains the press release. even during periods of enormous strain like live broadcasts and eSports tournaments. The cost of transactions within Level Up Chain will be minimal, and the team at Play2Live estimates that the fees will be maintained at $0.01 per transaction. However, the sub-chains use Proof of Machine for validation purposes, as the white paper explains: Sub-chain is independent from each other, and the number of sub-chain can be extended when necessary. Prime-chain is decentralized and distributed network that is immutable transparent to the public. Many large mining pools in Bitcoin actually provide the service of helping you merge mine many compatible coins at once. So for example, the largest Bitcoin mining pool, GHash.IO or Gigahash.IO allows you to simultaneously mine on Bitcoin, Namecoin, IXCoin, and Devcoin. So these become the most popular Bitcoin compatible merge mined altcoins.
