Ethereum Classic

Ethereum Classic is an open, decentralized, and permissionless public blockchain, that aims to fulfill the original promise of Ethereum, as a platform where smart contracts are free from third-party interference. ETC prioritizes trust-minimization, network security, and integrity. All network upgrades are non-contentious with the aim to fix critical issues or to add value with newly proposed features; never to create new tokens, or to bail out flawed smart contracts and their interest groups.

Ultimate glossary of crypto currency terms, acronyms and abbreviations

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

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants

Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants… Bonne découverte!
La guerre contre Bitcoin
Bitcoin est peut-être le meilleur outil de liberté économique de cette génération, et peut-être depuis plusieurs générations. Malheureusement, Bitcoin a été furieusement étouffé par une guerre civile brutale depuis environ cinq ans maintenant; menée par des ingénieurs sociaux professionnels de certaines des entreprises les plus puissantes des médias sociaux. Leur talent dans l'art et la science de la manipulation a permis aux "Bitcoiners" de se battre largement entre eux plutôt que de chercher à créer des modèles commerciaux innovants basés sur les données qui pourraient révolutionner l'économie mondiale via Bitcoin.
À la suite de la guerre civile de Bitcoin, trois versions concurrentes de Bitcoin ont vu le jour (BTC, BCH et BitcoinSV ), mais il en est de même pour environ 3000 autres projets et jetons de « crypto-monnaie » se faisant passer pour des entreprises légitimes, souvent jusqu'à un "exit scam" presque garanti, le fait de disparaitre du jour au lendemain avec tout l'argent des utilisateurs. Le principal bienfaiteur de la guerre civile Bitcoin a été Ethereum: une cryptomonnaie qui fonctionne comme une machine à états mondiale et permet un déploiement facile de tokens et de contrats intelligents. Mais le protocole Ethereum ne peut pas évoluer, et parmi les milliers de projets lancés, seule une poignée pourrait même être présentés comme pouvant devenir des entreprises légitimes. La plupart des autres sont des stratagèmes de Ponzi ou des émissions d'actions illégales enrichissant les développeurs et escroquant les investisseurs amateurs.
C'est dans ce contexte que les défenseurs de BTC et de BCH, les porte-parole d'Ethereum et les altcoiners (nom donné pour englober toutes les autres cryptomonnaies) de tous bords s'alignent pour attaquer sans cesse le protocole Bitcoin préservé uniquement par le réseau BSV. Une industrie composée presque entièrement de criminels, de fraudes et d'arnaqueurs s'est unie contre BSV citant - et c'est là l'ironie! - une prétendue fraude et arnaque présumée qui serait l'existence même de BSV.
Nous devons nous demander pourquoi ?
Quel est le différenciateur clé de BSV?
Pourquoi tous les arnaqueurs se sont-ils unis contre lui?
Je suis fermement convaincu que pour la plupart, la motivation est la peur de la capacité de BSV à absorber l'économie mondiale et tous les autres projets «crypto» qui vont avec. Pour les autres, ou ceux qui ne comprennent pas le pouvoir du Bitcoin, ils sont entraînés dans une guerre civile et culturelle qui les dépasse. Il est essentiel de comprendre les pouvoirs en jeu et leurs implications pour Bitcoin et l'économie mondiale.
Une histoire brève de Bitcoin
Bitcoin a été lancé avec un "livre blanc" sur la liste de diffusion de cryptographie en 2008. Le pseudonyme « Satoshi Nakamoto » a déclaré une solution au problème de la double dépense. Or il s'agit là du problème de tous les systèmes de paiement électronique précédents, et c'était le seul facteur limitant l'adoption d'une monnaie digitale fonctionnelle. Mais qu'est-ce que le problème de la double dépense ? Pour faire simple, il était impossible de prouver exactement qui possédait quelles unités d'argent sur des registres distribués, de sorte que les utilisateurs ne pouvaient pas avoir confiance dans le système, et ces projets mourraient assez vite. Bitcoin a résolu ce problème avec un concept appelé la « preuve de travail ». Il pose la question: qui a utilisé le plus de puissance de calcul pour résoudre des énigmes arbitraires ? ceci afin de rendre compte de l'état du registre d'une manière qui coûte de l'argent, de sorte qu'il y ait une incitation économique à tenir un compte honnête des avoirs de chacun des participants. Ce processus est souvent appelé « exploitation minière » car les nœuds honnêtes qui maintiennent l'état du registre sont récompensés pour leur travail avec des nouveaux Bitcoins toutes les dix minutes - un peu à la même manière d'un mineur d'or qui est récompensé par de l'or en échange de son travail.
Étant donné que Bitcoin n'avait aucune valeur lors de son lancement, il était extrêmement facile à miner et également gratuit d'envoyer des tonnes de transactions. En théorie, il s'agissait d'un vecteur d'attaque par déni de service (DoS). Une attaque DoS ou DDoS se produit lorsque les nœuds d'un réseau sont inondés de plus de données qu'ils ne peuvent en gérer et qu'ils se mettent donc à planter. Sur le jeune réseau Bitcoin, un crash comme celui-ci aurait été considéré comme un échec du réseau. Pour empêcher cela, un plafond de 1 Mo de données par chaque dix minutes de transactions a été codé en dur dans le logiciel - semant la première graine de la guerre civile Bitcoin. De 2009 à 2017, cette limite de 1 Mo sur le total des transactions était l'aspect technique le plus controversé du bitcoin et le déclencheur de la plus grande guerre civile virtuelle de l'univers de la cryptomonnaie.
Pourquoi est-ce aussi important?
Une seule transaction basique Bitcoin est relativement petite du point de vue des données, donc 1 Mo toutes les dix minutes donne environ trois à sept transactions par seconde avant que le réseau ne devienne trop encombré. Satoshi Nakamoto le créateur, a plaidé pour un nombre de transactions du niveau de Visa et bien plus, ainsi que son successeur direct en tant que développeur principal du projet, Gavin Andresen. Certains des premiers Bitcoiners influents comme Mike Hearn et Jeff Garzik ont ​​également plaidé pour plus de données par bloc pour permettre à Bitcoin de se développer et de rester le meilleur système de paiement électronique. Ils étaient pour des «gros blocs» contrairement au camp des «petits blocs» qui préconisaient une permanence de la limitation de 1 Mo des blocs.
Le camp des "petits blocs" estiment que Bitcoin n'est pas un réseau de paiement, mais plutôt qu'il s'apparente davantage à une banque décentralisée conçue pour stocker des Bitcoins qui ne bougent jamais: une sorte de coffre-fort d'or numérique. Ils voulaient que la limite de taille des blocs de 1 Mo reste permanente sous les auspices de chaque personne exécutant un «nœud complet» sans avoir à payer trop d'espace sur le disque dur. Cela signifierait qu'en période de congestion, les frais de transaction deviendraient absurdement élevés, mais cela n'aurait pas d'importance car le bitcoin ne devrait pas être utilisé pour des envois sauf en grosses quantités de toute façon, selon eux. En décembre 2017 les frais de BTC ont ainsi atteint les $50 par transaction. L'autre problème est que s'il est bon marché de rejoindre la gouvernance de Bitcoin, alors le réseau est facile à attaquer par Sybil, et je dirais que BTC est régi par des sybilles à ce jour.
Le camp des "gros-blocs" estime que tout le monde sur terre devrait être en mesure d'échanger et de faire ses affaires sur Bitcoin pour des frais infimes, de l'ordre d'un centième ou millième de centime par transaction, afin d'apporter à la population mondiale la liberté monétaire, y compris aux pays les plus pauvres qui sont gardés en dehors du système actuel car considérés comme pas assez profitables pour des entreprises comme Visa.
Les "petits-blocs" pensent que tout le monde devrait être en mesure de gérer soi-même le registre mondial chez soi, mais que seules certaines personnes très riches devraient pouvoir effectuer des transactions, ce qui est le cas quand les frais sont à $50 par transaction comme en 2017.
Après des années de querelles, en 2017, Bitcoin s'est scindé en deux chaînes distinctes, et en 2018, il s'est à nouveau divisé.
Alors quelle est la différence entre ces trois versions ?
BTC est actuellement la version qui a le prix le plus élevé, avec la plus petite taille de bloc et la plus grande puissance de calcul. On peut dire que BTC à gagné la guerre médiatique. Malheureusement, il est régi par des développeurs et des sybilles qui contrôlent le consensus grâce à une utilisation intelligente de logiciels malveillants appelés «soft-fork» qui leur permet de saper les règles du Bitcoin. Ils utilisent ce pouvoir pour changer les règles des transactions en mentant aux nœuds et en leur disant de les valider quand même. Toute la culture BTC consiste à acheter du BTC afin de le conserver jusqu'à un moment dans le futur où il serait revendu à un prix exorbitant. Le but est de spéculer au maximum. Les paiements avec BTC, particulièrement les petits paiements, ou les transactions de toute nature non-monétaires, sont méprisés.
BCH est un réseau basé sur Bitcoin qui pense que les blocs devraient être à peine légèrement plus grands, mais ils ont également des développeurs en charge des règles, tout comme BTC, et ils pensent que Bitcoin devrait être utilisé uniquement pour le commerce de détail, mais rien de plus. Le réseau change de règles tous les six mois. Les transactions non commerciales sont en général méprisées. Un nouveau scindement de BCH est prévu pour novembre 2020 suite à des conflits internes et l'incapacité à avoir un système de gouvernance dans un projet où les règles changent en permanence.
BSV est la version restaurée du protocole Bitcoin original avec tous les paramètres ouverts afin que les nœuds honnêtes puissent s'engager dans un consensus conformément au livre blanc de Bitcoin - par la preuve de travail ! Le protocole est gravé dans la pierre afin que les développeurs de logiciels ne puissent pas bricoler les règles. Cela permet aux entreprises de planifier des décennies d'utilisation du réseau et d'investir en toute confiance. Il s'agit d'apporter une réelle innovation technologique au monde plutôt que de spéculer. En tant que seul réseau bitcoin totalement sans besoin d'autorisation, le commerce de toute nature est encouragé sur BSV. Tout, allant des réseaux sociaux aux expériences de science des données météorologiques ou aux tests de disponibilité du réseau, est encouragé. Paiements de détail, tokenisation, ou tout autre type de contrat intelligent est simple à déployer sans limitations. Bitcoin SV n'a aucune limite dans son protocole sauf l'esprit humain, l'innovation et l'esprit d'entreprise. Il vise également une adoption mondiale notamment par les pays pauvres afin d'apporter la liberté monétaire et l'inclusion à l'économie mondiale de ceux que les grandes entreprises actuelles comme Visa dédaignent comme pas assez profitables pour leur accorder leur services.
Et c'est la racine de la haine envers BSV.
Les "petits-blocs" ont investi toute leur réputation et leurs moyens de subsistance sur la notion que le bitcoin est incapable de s'adapter. Pendant des années, des experts présumés ont convaincu de nombreuses personnes que les limites de taille de bloc de 2 Mo, 8 Mo ou 22 Mo casseraient littéralement Bitcoin. Ils ont furieusement mis en jeux leur réputation sur ces fausses notions. Et ensuite, BSV a eu de nombreux blocs de plus de 100 Mo. En fait, il y en a même eu quelques-uns de plus de 300 Mo! prouvant que les petits-blocs se trompaient depuis le début sur les limites du réseau. Mais cette prise de conscience est une menace pour l'hégémonie de l'histoire médiatique qui a été crée sur Bitcoin. Depuis 2015, lorsque le Dr Craig Wright est apparu sur les lieux pour expliquer que le bitcoin avait en réalité ZERO limitations, il a créé un tollé massif parmi l'intelligentsia des petits-blocs. Les leaders d'opinion de l'époque étaient payés pour prendre la parole lors de conférences où ils expliquaient à tort que Bitcoin n'était rien d'autre qu'une réserve de valeur rare sans autre utilité, et surtout pas à usage des plus pauvres. Le Dr Wright parlait de l'échelle illimitée du réseau, de son exhaustivité de Turing, de l'objectif d'inclure enfin les plus pauvres dans l'économie mondiale, et d'autres notions inconcevables (à l'époque) sur Bitcoin. Sa passion et ses connaissances se sont heurtées à des calomnies et des railleries. Ils se sont concentrés sur l'attaque de son personnage au lieu de discuter de Bitcoin!
C'est devenu l'une des principales méthodes d'attaque des petits-blocs. Lorsque de gros-blocs parlent des capacités de Bitcoin, ils sont ridiculisés en tant qu'escrocs et le sujet est toujours dirigé très loin de la discussion technique, car les petits-blocs savent bien qu'ils sortiraient perdants. Ils fouillent les dossiers personnels et cherchent des moyens de faire taire les gens du camp des grands-blocs de Bitcoin par des attaques personnelles - de la même manière que les guerriers de la justice sociale s'engagent dans la culture d'annulation contre leurs ennemis politiques.
Qui est le Dr Craig Wright et que fait-il?
Craig Wright est le scientifique en chef d'une société de recherche sur Bitcoin au Royaume-Uni appelée nChain : une société de 150 à 200 informaticiens. Craig dirige l'équipe qui étudie les possibilités de Bitcoin et de ses applications dans le monde. Il est l'un des experts en criminalité numérique les plus reconnus au monde avec les certifications SANS et GIAC ainsi que les titres GSE CISSP, CISA, CISM, CCE, GCFA, GLEG, GREM et GSPA. En outre, il est un polymathe multidisciplinaire de troisième cycle: un doctorat en informatique, économie et théologie et titulaire d'une maîtrise en statistique et en droit commercial international.
En 2015, il a également été exposé par une publication conjointe de WIRED et Gizmodo en tant que Satoshi Nakamoto, le créateur de Bitcoin. Quelques jours après cette révélation, les gens qui le soutenaient ont vu leurs clés d'accès au code de Bitcoin révoquées, et de nombreux autres ont été instantanément bannis. Craig a été mis sous enquête par le bureau des impôts australien pour ce qu'il considérait être une erreur de comptabilisation probable de ses bitcoins. Les retombées ont été agressives et rapides, avec une gigantesque armée de petits-blocs, organisée sur Reddit et d'autres forums, et nouvellement financés par l'argent de la startup pro petits-blocs appelée «Blockstream». Leur message était clair: Bitcoin doit garder de petits blocs. Le Bitcoin ne peut pas évoluer et doit rester réservé aux riches, et toute personne proche de Craig Wright sera harcelée pour se conformer à une armée de comptes Twitter anonymes et sans visage.
Voici un schéma qui retrace les financements de Blockstream et révèle comment le groupe Bilderberg, la banque centrale américaine (FED) et Mastercard on pris le contrôle du réseau BTC via Blockstream afin de le soumettre à leur propre profit: https://imgur.com/eFApDVE
Au cours des années suivantes, Ira Kleiman, frère du défunt Dave Kleiman, a poursuivi Craig Wright en justice pour sa part du prétendu «Partenariat Satoshi Nakamoto», affirmant que son frère Dave était plus impliqué qu'il ne l'était réellement, et l'affaire est en cours actuellement, jusqu'à courant 2021. Ira Kleiman pense que Craig est Satoshi et il a investi une fortune incalculable dans cette attaque et a obtenu l'argent d'investisseurs extérieurs pour poursuivre sa poursuite. Il est clair que les bailleurs de fonds d'Ira pensent que Craig est également Satoshi.
Les critiques qualifient souvent la révélation publique et le procès public de Wright de ternir énormément sa réputation, mais il convient de noter que les deux sont arrivés à Wright malgré sa volonté et qu'il ne souhaitait clairement pas être pris dans l'une ou l'autre situation.
Au lieu de cela, Craig est un défenseur passionné de la vision d'un Bitcoin avec de gros blocs, appelant à la professionnalisation, à la légalisation et à l'utilisation mondiale de Bitcoin pour une utilisation à tous les niveaux du commerce. La réponse à la passion de Craig et à ses affirmations a été d'attaquer sa réputation et d'endosser Internet avec le surnom de «Faketoshi». Lorsque de simples brimades ont échoué contre le Dr Wright, des attaques ont été intensifiées pour remettre en question ses divers diplômes, des pétitions aux universités pour enquêter sur lui pour plagiat dans divers travaux, y compris des thèses de doctorat, etc. Wright a même revendiqué des menaces contre la vie des membres de sa famille et il y a plus qu'une preuve que, selon Ian Grigg, une des légendes de la cryptographie: «des gens sont morts pour Bitcoin, croyez moi, des gens sont morts».
Les attaques en cours
Cela ne peut être assez souligné: la communauté des petits-blocs est construite autour de tactiques d'ingénierie sociale professionnelles. Gregory Maxwell, co-fondateur de la société Blockstream, a été formé à la pratique de l'ingénierie sociale et l'a utilisé de manière si subversive comme un outil de propagande pendant son mandat en tant que modérateur rémunéré de Wikipedia, qu'il a finalement été démis de ses fonctions avec les journaux d'administration citant une litanie d'infractions, notamment:
«Gmaxwell s'est engagé dans la création de faux comptes en masse…» - Alhutch 00:05, 23 janvier 2006 (UTC)
«Menaces, insultes grossières, usurpations d'identité d'un administrateur», -Husnock 03:18, 25 janvier 2006 (UTC)
«Son comportement est scandaleux. Franchement, il est hors de contrôle à ce stade. Son comportement d'intimidation doit cesser.» - FearÉIREANN 19:36, 22 janvier 2006 (UTC)
«Sa liste de contributions est hors de propos. C'est du vandalisme. C'est un comportement auquel je m'attendrais d'un éditeur en furie, et franchement, c'est ce qu'est Gmaxwell.» - Splashtalk 20h00, 22 janvier 2006 (UTC)
«Prétend être un administrateur, menaçant de bloquer les personnes qui ne sont pas d'accord avec lui, fait régulièrement des attaques personnelles» - SlimVirgin (talk) 12h22, 22 janvier 2006 (UTC)
Il passe beaucoup de temps sur Reddit et d'autres forums à semer la peur sur les dangers des gros blocs, et il a été surpris en train de faire semblant d'être plusieurs comptes à la fois en train d'avoir de très longues discussions techniques sur Reddit destinées à submerger les nouveaux arrivants avec ce qui ressemble à un débat intellectuel contre une version de Bitcoin libéré de ses limites.
Qui d'autre est attaqué?
L'autre cible commune de la machine de guerre médiatique anti-BSV est Calvin Ayre: un milliardaire à la tête de l'empire du groupe Ayre. Calvin est un entrepreneur canadien et antiguais qui a lancé un incubateur Internet à Vancouver au tout début du boom Internet. Fils d'un éleveur, Ayre est surtout connu en dehors de l'économie Bitcoin pour la création et la professionnalisation de l'industrie du jeu sur Internet. Plus particulièrement, sous la marque Bodog, Ayre a aidé à moderniser les lois financières américaines obsolètes en poussant les limites dans les marchés gris qui existent où les dollars américains sont utilisés à travers les frontières pour s'engager dans un commerce juridiquement compliqué comme le jeu d'argent. Son travail dans ce domaine lui a valu une petite fortune et un passage sur la liste des «plus recherchés» du gouvernement des USA pour blanchiment d'argent. C'est un point sur lequel les petits-blocs aiment se concentrer, mais ils le sortent complètement de son contexte. Calvin a finalement plaidé coupable à une accusation mais a été le fer de lance de la modernisation des lois américaines qui existent aujourd'hui sur les marchés. Il est respecté pour son travail dans l'industrie du jeu, des médias et de la philanthropie. Calvin est le bienvenu aux États-Unis malgré la critique souvent citée selon laquelle il serait une sorte de hors-la-loi.
Calvin Ayre
Dans l'économie Bitcoin, Ayre est une figure de proue dans la gestion de nœuds Bitcoin honnêtes depuis plusieurs années sous les marques CoinGeek et TAAL, et il est un investisseur dans nChain ainsi que plusieurs startups de l'espace BSV. Bien qu'il soit probablement le plus gros investisseur à ce jour, il n'est pas le monopole que les petits-blocs laisseraient croire. Il est important de comprendre que des segments entiers de l'écosystème BSV existent complètement en dehors de son influence.
Twetch, par exemple, est une entreprise indépendante appartenant à l'écosystème BSV, célèbre pour ses attaques contre les médias sociaux centralisés qui abusent de la censure. Ils sont même connus pour se moquer des entreprises qui acceptent l'argent d'Ayre, en plaisantant que Calvin possède tout sauf Twetch. Bien sûr, ce n'est pas vrai. Un autre excellent exemple est l'investisseur / entrepreneur indépendant Jack Liu : ancien dirigeant de Circle et OKEX. Liu possède la marque de hackathons CambrianSV ainsi que des propriétés précieuses dans l'espace BSV telles que RelayX, Streamanity, Output Capital, FloatSV et Dimely.
Les autres acteurs clés sont MatterPool Mining et leur écosystème Mattercloud: une joint-venture entre des acteurs indépendants de l'écosystème BSV, avec des connexions directes aux protocoles BoostPOW et 21e8 et des relations avec des développeurs BSV indépendants.
Bien sûr, il existe également des marques précieuses financées par Ayre. Il s'agit notamment de la propriété partielle via l'investissement dans HandCash, Centi, TonicPow et Planaria Corp de Unwriter.
Une autre mesure importante à prendre en compte est la distribution de la puissance de hachage (autre nom pour la puissance de calcul du résau). Alors qu'au tout début de BSV, les entreprises appartenant à Ayre représentaient une quantité importante de hachage sur bitcoin, afin d'assurer sa survie, BSV est aujourd'hui en grande partie exploité par des mineurs concurrents de Ayre tels que Binance, F2Pool, OKEX et ViaBTC - dont aucun n'est «ami» de BSV ou d'Ayre, mais beaucoup se déclarent les ennemis. Ces mineurs soulignent bien la nature ouverte et sans permission de BSV qui permet à quiconque de participer, notamment à ses ennemis!
Ayre est un acteur important, mais en aucun cas un contrôleur de la direction de la blockchain ou des entreprises indépendantes dans l'économie BSV.
Mais pourquoi Craig poursuit-il des gens en justice ?
Tout d'abord, et c'est crucial, le procès le plus important de Craig est l'affaire Kleiman. Les autres cas existent uniquement à cause de la diffamation publique du Dr Wright. Le hashtag #CraigWrightIsAFraud circule largement, poussé en grande partie par un mélange de personnages anonymes sur Twitter. Plus particulièrement Magnus Granath AKA «Hodlonaut» a été averti qu'une accusation publique de fraude courait à son encontre. La carrière du Dr Wright est en informatique et en criminalistique numérique, donc le déclarer publiquement une fraude sans preuve cause un préjudice financier au Dr Wright dans son domaine d'expertise commerciale. Puisque «Hodlnaut» a refusé de cesser, on lui a envoyer une requête pour être vu au tribunal afin de pouvoir apporter les preuves de ses accusations. Cela a causé le célèbre podcasteur de petits-blocs Peter McCormack à mendier d'être poursuivi aussi - en augmentant la rhétorique diffamatoire contre le Dr Wright. À la demande de McCormack, il a lui aussi été attaqué en justice pour être vu au tribunal. Le Dr Wright à depuis abandonné tous ses procès pour diffamation à l'exception de celui contre McCormack qu'il souhaite continuer pour faire exemple.
Cela a aussi engendré la campagne #DelistBSV menée en grande partie par «CZ», le PDG charismatique de Binance-Exchange. Divers autres échanges comme Shapeshift et Kraken ont publié des sondages twitter demandant s'ils devaient emboîter le pas, et des petits-blocs bien organisés ont voté en masse pour retirer BSV de leurs échanges - citant la toxicité du Dr Wright pour avoir intenté des poursuites en diffamation contre Hodlonaut et McCormack. Finalement, BSV a été retiré de Binance, ShapeShift et Kraken. Il a également été noté publiquement par Coinbase et Gemini qu'ils ne soutiendraient pas cette version de bitcoin à la suite de ce drame public. Il faut noter qu'après 2 ans, Binance a retourné sa veste et est aujourd'hui devenu un des principaux mineurs de BSV.
Au fur et à mesure que les choses progressaient, le fondateur de bitcoin .com, Roger Ver, a également réalisé une vidéo publique déclarant Wright comme arnaqueur. C'était après avoir travaillé sournoisement avec les développeurs Bitcoin ABC pour coder des points de contrôle dans le logiciel ABC de Bitcoin Cash, divisant de manière permanente le réseau Bitcoin pour la deuxième et dernière fois - un acte auquel le Dr Wright s'était opposé et pour lequel Roger est également poursuivi par d'autres parties privées en Floride. Roger Ver a été averti que s'il continuait, des poursuites juridiques similaires se présenteraient à sa porte pour avoir diffamé le Dr Wright, mais il à décidé de poursuivre les accusations publiques jusqu'à ce qu'il soit également entendu devant le tribunal pour fournir une preuve de la fraude de Wright, sous peine de sanctions pour diffamation publique. Aucune preuve n'a jamais été fournit, mais le Dr Wright a depuis abandonné ses poursuites contre Roger Ver pour se concentrer sur son procès avec Kleiman et celui avec McCormack ainsi que son travail sur Bitcoin.
Et maintenant que se passe-t-il ?
Nous avons établi l'histoire du Bitcoin, de sa guerre civile, des attaques publiques contre Wright, Ayre et BSV. Au moment d'écrire ces lignes, nous pouvons revenir sur les attaques contre Thomas Lee, Tim Draper et Jimmy Wales pour avoir eu une proximité avec BSV. Malgré la pression sociale, le rapport technique Fundstrat de Lee a rendu un examen élogieux du protocole fixe et de l'évolutivité infinie de BSV. Lee et son équipe étaient heureux de prendre la parole lors des événements précédents de CoinGeek, même après le tollé public.
Pour la conférence CoinGeek 2020 à New York, McCormack, Hodlonaut, « Arthur Van Pelt » et d'autres acteurs tels que le Dan Held de Kraken et une cacophonie de trolls anonymes sur Twitter ont mis à profit leur expérience de la culture d'annulation à la bolchevique pour faire pression sur l'orateur Gary Vaynerchuk ainsi que d'autres orateurs prévus pour cette conférence, afin de les forcer à annuler leur participation. Cette attaque sociale contre BSV, Dr. Wright, Ayre et les autres entreprises qui utilisent le réseau BSV pourrait être un gigantesque cas de fraude à la consommation. Ils trompent activement les gens en leur faisant croire que le protocole fixe et l'évolutivité infinie de Bitcoin BSV sont en quelque sorte dangereux, alors qu'en fait, le protocole et le réseau sont imperméables à toutes les attaques, à l'exception de leur ingénierie sociale.
Bitcoin SV s'est développé professionnellement avec un portefeuille de brevets de protection de niveau mondial. Il est utilisé par des entreprises indépendantes afin d'apporter des innovations technologiques et possède un groupe décentralisé de nœuds honnêtes qui se font concurrence. Le réseau est fixe, sécurisé et en croissance grâce aux investissements de petites entreprises et de gestionnaires de capitaux. Les transactions sont instantanées avec des frais de 0.0002€ par transaction en moyenne, explosant tous les records de compétitivité de l'écosystème et permettant aux plus pauvres de la planète d'enfin accéder à l'économie digitale mondiale. Les mensonges sont basés sur une campagne massive de dénigrement perpétrée par les communautés d'autres cryptomonnaies qui craignent l'adoption mondiale de BSV comme outil de commerce et ce que cela signifiera pour eux. L'histoire ne sera pas gentille avec ces manipulateurs et leurs réseaux qui sont financés par les fraudes probables des échanges de crypto-monnaies off-shore, le (très probablement) frauduleux Tether Stablecoin, et l'économie des arnaques de "pump-and-dump" qui sous-tend 95% du volume de négociation de l'ensemble de l'économie cryptomonnaie actuelle.
C'est une guerre civile. Il y aura toujours des victimes, mais alors que BTC et BCH se concentrent sur les ragots et les affaires illicites, BSV veut que le monde entier soit plus libre, plus souverain et plus capable de coopérer sur le registre mondial de la vérité afin que les entrepreneurs du monde puissent s'engager à créer des entreprises ou de simples nano-services sont rendus possibles uniquement par Bitcoin. Bitcoin est un test d'intelligence. Au fil du temps, les personnes intelligentes pourront voir à travers le brouillard de distorsion de la réalité créé pour confondre les innocents et reconnaître cela pour ce que c'est, une attaque coordonnée pour tenter de supprimer une technologie qui à un potentiel unique dans l'histoire, et qui les rendrait obsolètes.

Disperse big players and refuse to monopolize

Avoid the risk of smashing the stocks of large investors, diversify the account to reduce the risk
With the development of blockchain technology, it is no longer satisfied with only obtaining data on the chain. How to bridge the connection between the real world and the blockchain world has always been the direction of technological conquest, and the oracle plays this role. Especially with the popularity of the DeFi concept, the large-scale application of Oracle Machine (Oracle Machine) in financial derivatives trading platforms, gambling games, and prediction markets has made it a new track in the industry.
At present, the oracle project represented by EULER is operating well, continues to lead the trend of oracle development, and continues to consolidate the basic technical support for the DeFi revolution. Its already-online mining design is also refreshing.
EULER's platform pass EUCC, 90% of which is used for mining output, and the entire mining mechanism runs through the distributed oracle protocol, in which three roles are set up: data provider, data verifier, and arbitration node. And reward and punishment mechanism to ensure ecological operation.
How does EULER mine? Is it a new wealth code? What are the characteristics? With these questions, let us analyze the distribution mechanism, mining mechanism, and token value one by one.
The mining mechanism is fairer, and small and medium miners benefit more
Before talking about the mining mechanism of EUCC, we can look at the distribution of other tokens. The blockchain itself upholds fairness and justice, without permission, so that everyone in the network can participate. However, when we look at Bitcoin mining, it is now monopolized by several mining machine vendors such as Bitmain, and ordinary people cannot participate at all. If a PoW husband chain like Bitcoin has formed the head effect of mining, what about a relatively fair PoS type blockchain? Let's take Cosmos as an example. Since Binance joined its validator node, it has instantly ranked to the top with the strong financial strength and user base of the top exchange, and does not give small and medium nodes the slightest chance.
Looking back at the mining mechanism of EUCC, we can find that it is very friendly to ordinary users. Assuming that 6.3 million EUCCs are scattered to the accounts of 12 individuals, 8 of them hold 1 million, 1 person holds 99.9 million, and one person holds 5,299,800. Our income is related to the ranking. We give a flashback ranking of 12 people's currency holdings.
The staking ranking is based on the jump ranking weighting algorithm rather than the weighted average of the user staking amount. This is to avoid EUCC being controlled by a few people, avoid monopoly, and break up large users. Do your best to achieve a win-win situation in EULER's community.
Decentralized tokens create a closed loop: Euler platform currency EUCC flashback ranking reverse order weighting algorithm mechanism
The EUCC currency holding and promotion revenue is set through the reverse ranking weighting algorithm of the reverse order to achieve a small number of rows, and the best currency holding is the most ideal. Disperse large accounts, avoid the formation of monopoly, and at the same time encourage currency holding, encourage the whole network to increase the position to catch up, prevent EUCC from being controlled by a few wealthy people and market oligarchs and affect circulation, and use personal efforts to determine you to get promotion benefits while driving users Fission keeps the whole network dynamic.
Compared with other mining projects, EULER has introduced a unique flashback ranking weighting algorithm mechanism in the mining design, which provides a good mechanism guarantee for attracting more users to participate in mining, and it is also beneficial to data providers. Decentralization ensures the decentralization of the oracle system and well guarantees the positive development of the community.

Themis (MIS) Launches Pledge Mining Platform, New Opportunity Occurs to Grow Wealth

Themis (MIS) Launches Pledge Mining Platform, New Opportunity Occurs to Grow Wealth
With the development of blockchain technology, obtaining data on the chain only is no longer satisfying and how to bridge the real world and the blockchain world has always been the direction of the technological breakthrough. Under this background, Oracle Machine came to our attention. In particular, with the popularity of the DeFi concept, the industry starts to witness a boom of the application of Oracle Machine in financial derivatives, trading platforms, gambling games, and prediction markets.
At present, Oracle Machine represented by Themis is developing fast with a good momentum, leading the trend of the development of Oracle Machine and continuing to consolidate the basic technical support for the DeFi revolution. Themis’ mining system has been launched in the market, which is refreshing and appealing (see https://themisoracle.com/#/credit for details on the Themis mining).
90% of MIS, the native token of Themis, will be used for mining output. The entire mining mechanism runs through a distributed oracle protocol, which sets up three roles: data provider, data validator, and arbitration node. Reward and punishment mechanisms are applied to ensure the smooth ecological operation.
How does Themis mining work? Is it a new way to become wealthy? What are the characteristics? To answer these questions, we need to analyse the distribution mechanism, mining mechanism, and token value of Themis.
With a fairer mining mechanism, small and medium-sized miners can enjoy better benefits
One of the core values of blockchain is fairness and justice, and allowing everyone in the network to play a role in the system without permission. However, Bitcoin mining is now monopolized by several mining machine vendors such as Bitmain, leaving little space for other miners to participate. If those old PoW public chains, such as Bitcoin, has formed the head effect in mining, what about those new projects? Let's take Cosmos as an example. Since Binance joined its validator node, it has instantly ranked top with the strong financial strength and user base of the top exchange, making the small and medium nodes hard to participate.
After comparison, we can find that the mining mechanism of MIS is very friendly to ordinary users. Assuming that there are 12 mining transactions in a block, the ranking according to the MIS pledged by each transaction would be as follow:
https://preview.redd.it/1kfccgps2pg51.png?width=832&format=png&auto=webp&s=bf6c7f614c600826006bc2bf8a6026292c3b328c
The pledge ranking is based on the jump ranking weighting algorithm rather than the weighted average of the user pledge amount, which can prevent MIS from being controlled by a small number of people, avoid monopoly, creating a win-win situation in the Themis community.

https://preview.redd.it/pme9tcd62pg51.png?width=832&format=png&auto=webp&s=049f899d2a5ee3ce64007d5cc0ae3ed6167c2b3a
Compared with other mining projects, Themis has introduced a unique pledge ranking method in the mining design. Users in the best ranking area will get the most benefits, which is a good mechanism guarantee for attracting more users to participate in mining. At the same time, it can lead to the decentralization of data providers, ensuring the decentralization of the oracle system and the positive development of the community.
How can miners join in Themis mining? The answer is to become a part of the ecology by playing the role of either data provider, data validator, or arbitration node.
The data provider is mainly responsible for providing various types of data, and the data validator verifies and challenges the data offered by the data provider and provides new data. The arbitration node arbitrates the query raised by the data validator and come up with the final result.
Both the data providers and validators of Themis need to pledge MIS to obtain the qualifications, and the caller of external data also needs to pay MIS assets when accessing the data of Themis oracles. If the data has been verified as correct, data providers and validators will receive mining rewards, and the more they pledge, the more rewards they will receive.
In the mining design of Themis, miners can acquire MIS by providing verifiable random number or offering the price of in-chain assets. Whenever miners call mining contracts, the system will charge no service fee (excluding the service fee of ETH). In addition, if no mining transaction occurs within a certain period of time, the first newly-emerging block containing mining transactions will acquire all the MIS rewards. In this way, miners can be encouraged to continue mining and maintain the ecological stability of Themis.
The number of MIS mining for each mining transaction of miners is calculated as follows:
First, calculate the number of MIS mining rewards N contained in the block of the packaged mining transaction. If the height difference between the block and the previous block containing the mining transaction is y, then N = y * 20.
The MIS mining quantity of this mining transaction is M, then M=Xi/(📷)×N. Among them, X is the ranking of the MIS pledge amount in the block, and those who pledge the same amount of MIS have the same ranking.
Few official pre-mining, while 90% belongs to the community
Based on the official announcement, the distribution of MIS is:
The total amount of MIS is 1 billion, 10% is reserved for early project promotion, the remaining 90% are produced by mining, in which 75% are directly awarded to data providers, 10% to developers, and 5% as reward for arbitration nodes and ecological incentive. The production of mining will be progressively decreased and released with ETH. For some current popular VC-invested projects, institutional holdings hold more than half of blocks and unlock the block every month, which is a huge stress for ordinary pledge users. Many projects also went wrong because institutional investors do not abide by the rules. For MIS, because there is fewer official pre-mining, the selling pressure will be smaller, which is more in line with the value of the blockchain.
The release plan of developer and arbitration node and ecological incentive is as follows:

https://preview.redd.it/nld8k8gb2pg51.jpg?width=926&format=pjpg&auto=webp&s=8c2435c993cf86b2bf6b0c4d2a1935708734de97
The release plan of data provider incentive is as follows:

https://preview.redd.it/kgia5n6d2pg51.jpg?width=982&format=pjpg&auto=webp&s=ad1bfe7796fdaec58f3caede2f2a2083c0a07724
The MIS awarded per block reduces by 10% in every 4 million blocks, and the reward per block at present is 20 MIS.
We can see that the allocation of MIS follows the following principles.
First of all, as MIS is the platform certificate of Themis, it is very reasonable to reserve 10% of MIS for early project promotion.
Secondly, 90% of MIS is produced through sustainable mining. This proportion can motivate contract users and miners to conduct contract mining, truly implementing the spirit of win-win community and token economy.
Finally, among the 90% of MIS, better incentive mechanisms have been adapted, mining reward ratios are subdivided, which can attract more investors to participate in mining.
Reasonable mining mechanism highlights the project value of Themis
Themis, as a public chain that provides a mechanism to solve the problems in Oracle Machine, has a unique charm in the value of MIS.
From the perspective of the number of tokens, the total amount of MIS is 1 billion, and the total mining pool is 900 million. 90% of the tokens are generated by mining, and the mining output gradually decreases its release with the Ethereum block, showing a great potential in its future added value. The earlier you participate in mining, the more profit you can gain.
From the perspective of Themis’s ecological design, Themis is committed to the original intention of building a price oracle. The data provider pays on-chain fees and pledges a certain amount of MIS, and determines the income obtained according to the scale of the pledge; the validator can make profit from challenging the data. Also, any smart contract developer or user need to pay the corresponding fee when calling Themis, and this part of the profit will be distributed to the data provider in proportion. Through this design, a logical closed loop is completed to ensure the healthy operation of the entire ecology and achieve the goal of mutual benefit. In Themis, all parties in the ecology can work together to grow more wealth.
In all, MIS has a huge potential for future development and arbitrage, and of course, a great profit potential as well.
Today, public chains like Themis are not just a technology platform, but also a symbol of future economic operation mode which connect between the blockchain and the real world. Themis, with a fair, justice and open network through mining, is building a strong token ecology, connecting external chain data and the systems, realising data interaction between blockchain and the real world, and more importantly, creating a new mode of token economy.

Why i’m bullish on Zilliqa (long read)

Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analysed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralised and scalable in my opinion.
 
Below I post my analysis why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since end of January 2019 with daily transaction rate growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralised and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. Maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realised early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralised, secure and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in amount of nodes. More nodes = higher transaction throughput and increased decentralisation. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue disecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as:
“A peer-to-peer, append-only datastore that uses consensus to synchronise cryptographically-secure data”.
 
Next he states that: >“blockchains are fundamentally systems for managing valid state transitions”.* For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralised and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimisation on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (>66%) double spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT etc. Another thing we haven’t looked at yet is the amount of decentralisation.
 
Decentralisation
 
Currently there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralised nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching their transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public.They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers.The 5% block rewards with an annual yield of 10.03% translates to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS & shard nodes and seed nodes becoming more decentralised too, Zilliqa qualifies for the label of decentralised in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. Faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time stamped so you’ll start right away with a platform introduction, R&D roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalised: programming languages can be divided into being ‘object oriented’ or ‘functional’. Here is an ELI5 given by software development academy: > “all programmes have two basic components, data – what the programme knows – and behaviour – what the programme can do with that data. So object-oriented programming states that combining data and related behaviours in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behaviour are different things and should be separated to ensure their clarity.”
 
Scilla is on the functional side and shares similarities with OCaml: > OCaml is a general purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognised by academics and won a so called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities safety is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa for Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue:
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships  
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organisations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggest that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already taking advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, AirBnB, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are build on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”*
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They dont just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities) also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiatives (correct me if I’m wrong though). This suggest in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures & Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

A guide to Smart Contracts

A guide to Smart Contracts

https://preview.redd.it/ysi74g2vn3251.png?width=1920&format=png&auto=webp&s=63875e316556c41144ad81cf061caf5bb3f4680d
We all have heard the term Smart Contract. When Satoshi invented Blockchain, it was meant to perform transactions only. Ethereum smart contracts made it the prime choice to build Dapps over it. Smart contract enhanced Ethereum’s functionality and makes it different from the traditional blockchain (Bitcoin). This functionality was replicated by other newer Blockchains.
What are Smart Contracts?
Smart contracts can be defined as self-executing applications that run on a blockchain. It is an agreement between two or more parties in the form of a computer code that runs on a decentralized network in a blockchain. It consists of a set of defined rules which are agreed upon by the involved parties. The contract automatically gets activated whenever certain conditions are met.
This idea will remove the involvement of any trusted third-party companies (such as banks) and will be controlled by computers on a trusted network.
Ethereum is one of the most popular blockchain platforms for creating smart contracts. It supports a feature called Turing-completeness that enables the developers to build customized smart contracts. Solidity, Ethereum’s original coding language is used to develop smart contracts. Ethereum blockchain's ERC-20 and ERC-721 tokens are smart contract standards.
Who created it?
Nick Szabo, a computer scientist, and cryptographer, first described the idea of Smart contracts in the ‘90s. He worked on the concept of defining contract laws in businesses between parties by maintaining an electronic commerce protocol on the Internet.
He further designed Bit Gold, a mechanism for a decentralized digital currency in 1998. Though the idea was never implemented it created a base that led to the popularity of Bitcoin after 10 years.
Properties:
· Self-verifiable
· Self-executable
· Tamper Proof
Benefits of using Smart Contract
· The removal of third-party or middleman leads to direct and transparent communication between involving parties
· Helps in maintaining trust as the agreement rules were predefined and agreed by the parties involved
· Helps in reducing error and frauds
· Time and cost-efficient
· No single point of failure or data loss as data is distributed across the network

https://preview.redd.it/1e5ahcqxn3251.png?width=1024&format=png&auto=webp&s=f8a1ebb9b3a84dd721fb32f96fc1950899bc3015
Different objects of Smart contracts
There are three essential and main objects of Smart Contracts
· Signatories- The parties who use the smart contract.
· Agreement subject
· Terms and Condition-. Details like rules, obligations, and associated punishments, etc are mentioned as terms and conditions as appropriate.
How Smart Contract works
Ethereum has 2 types of accounts
· External accounts (user account) - Controlled by public-private key pairs
· Contract accounts - Controlled by the code stored together with the account
These accounts contain four fields:
· The nonce, which ensures that each transaction can only be processed once
· The current ether balance of the account
· The contract code of the account
· The storage of the account
Model steps
  1. External account executes a function:
a. The user initiates the process by signing the transaction using his private key corresponding to the account.
b. Local validation of the transaction happens. It is broadcasted to the network.
c. The transaction is added to the transaction pool. The mines maintains such pools.
  1. Generate EVM bytecode through compiling
  2. EVM
a. EVM is a powerful, virtual sandbox embedded within each full Ethereum node
b. The job of the EVM is to update the Ethereum state by computing valid state transitions as a result of smart contact code execution
c. The EVM should not run into any exceptions during the execution
  1. Get contract address from that transaction's receipt
  2. Trigger contract address to invoke methods of that deployed smart contract
  3. Upon receiving a newly created block, the local node executes all the transactions in the block.
The accuracy and quality of a smart contract depends on the following things
· Open and decentralized database
· The environment needs to support the use of public-key cryptography
· Quality programming is crucial.
· Data should be reliable.
· Robust rules should be used while automating the process.
Features
Smart contracts automatically support the features of underlying blockchain technology.
· Autonomy – Complete control of the involving parties. No need of middleman as in the case of traditional contractual system
· Speed – Automated computer code runs as soon as the input criteria fulfill, thereby eliminating the delays caused by manual paperwork activity
· Safety – Network encryption guarantees safety against data theft or hacking
· Savings – No doubt that the removal of middleman saves a lot of overall cost and time
· Accuracy – Since these smart contracts are automated software codes so they ensure accurate output as long as the data fed into the system as input is accurate
· Trust – Helps in building trust as the documents are encrypted in a shared ledger
· Backup – Since in Blockchain network, each node has a complete backup of data which ensures protection over data loss
Potential Use cases
Smart contracts can be used to exchange money, property, shares, or anything without any intervention of middleman. They are now gaining popularity and adaption in various sectors. Some of the main sectors are as follows:-
· Insurance Companies
· Health Systems
· Government’s administrative work.
· Business Management
I will cover each of the potential use cases in detail in my future articles separately.
Conclusion
Smart Contract is the greatest innovation built on Blockchain technology. We can say it as a cherry over the pie. It has given a new dimension to technology and is one of the biggest reasons behind the popularity of Ethereum.
We can say without any second thought that very soon we will be entering into the era where there will be no intervention of any third party. In this way, it can help us in saving a lot of money, time, and effort. Also, we don’t need to be dependent or trust anyone while taking any crucial transactions. This will surely help in reducing fraud, unnecessary delays, and the overall cost of transactions. Smart Contracts will make many transactional jobs redundant. We can be hopeful that further development in technology will open sources for many other new jobs.
