Block hashing algorithm - Bitcoin Wiki

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

I posted this on /cryptotechnology . It attracted quite a bit of upvotes but not many potential contributors. Someone mentioned I should try this sub. I read the rules and it seems to fit within them. Hope this kind of post is alright here...
EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors.
TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [email protected] . Thanks in advance!
Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.
The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract.
The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data.
The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block.
To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block.
I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors.
The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract.
There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive).
The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only.
I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport.
When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software.
The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create:
A logistic and transportation company
A delivery company
A company that buy and sell real estate options
A company that manage real estate
A software development company
A world-wide fiat money transfer company
A payment processor company
We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money exchanges.
We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche.
I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper.
If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [email protected] .
If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed.
Thanks all in advance!
P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

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!

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

I originally posted this on /cryptocurrency. I just thought you guys might be able to help as well so I posted it as well. I didn't link to the original post because the bot here keeps deleting my post, even if I use the np link. Hope that's ok...
EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors.
TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [[email protected]](mailto:[email protected]) . Thanks in advance!
Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.
The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract.
The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data.
The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block.
To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block.
I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors.
The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract.
There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive).
The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only.
I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport.
When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software.
The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create:
  1. A logistic and transportation company
  2. A delivery company
  3. A company that buy and sell real estate options
  4. A company that manage real estate
  5. A software development company
  6. A world-wide fiat money transfer company
  7. A payment processor company
We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money.
We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche.
I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper.
If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [[email protected]](mailto:[email protected]) .
If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed.
Thanks all in advance!
P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

When is the difficulty adjustment algorithm going to be fixed?

When it comes to Bitcoin Cash's difficulty adjustment algorithm, it is having many issues. We've come across situations in which several consecutive blocks are mined in a few minutes, which can be bad for security, and the overall credibility of Bitcoin Cash. I've looked at the block explorer as well, and there are times when the antminer pool gets 5-6 blocks in 10 minutes. Though the average is still at the proper 10 minutes, I can foresee this causing many issues, and making Bitcoin Cash potentially fail. If this DAA isn't fixed, a big mining pool that is opposed to Bitcoin Cash can easily increase (and switch over hashrate from BTC to BCH), causing the difficulty to increase, and then leave the pool almost immediately so the pool of smaller hashrate will take SIGNIFICANTLY longer to solve that block. I have seen this at points where Bitcoin Cash blocks have gotten extremely long (ex. ~2 hours after the reward halving), and that's an issue that needs solving. I saw a video on youtube by u/jtoomim that explained this pretty well. This isn't the first time I've heard of this problem. I saw a thread that discussed how miners can "game" the DAA. Is there going to be a change in this adjustment algorithm anytime soon?

Generation of Coinbase Transaction

Hello Again,
I'm researching solo mining, but I need help in finding information on how the Coinbase Transaction is Generated:
It should be explained within the 'getblocktemplate' page on the Bitcoin Wiki (https://en.bitcoin.it), but this only explains how to build a coinbase transaction with the help of "coinbasetxn"; and it's my understanding that "coinbasetxn" is only supported within Mining Pools, not the Bitcoin Wallet - remember, I'm researching solo mining.
What's also making things complicated is "Segregated Witness" (Segwit): With Segwit, all transactions now have a 'txid' and a 'hash'; sometimes, the 'txid' and 'hash' will match, but most of the time (including in some Coinbase Transactions) they don't. And I can't find anything online on how to generate a Coinbase Transaction while accounting for Segwit.
Can anyone find an example algorithm that can build a Coinbase Transaction in a solo mining environment while also accounting for Segwit?
You can share it in any code you like, but I'd prefer Python.

If you missed the AMA

AMA AT DETECTIVE ID (25/06/2020)
Before welcoming any questions, I would like to briefly introduce STATERA PROJECT. Statera is a smart contract deflationary token pegged to a cryptocurrency index fund. By including STA in an index fund with Link, BTC, ETH, and SNX you can buy one token and access the price action of four of the leading cryptocurrencies. You can also invest directly in the index fund (balancer pool) and receive the benefits of fees and BAL tokens paid to you while also having an automatically balanced fund. Lastly the deflationary mechanics of STA increases the chance for positive price action while decreasing beta (volatility). This is all found in a smart contract that is fully decentralized, the founders can no longer augment the contract in any way and this has been confirmed by a third party code audit through Hacken.
Q1 : please explain in more detail about Statera, what is the background of this project? and when was it established?
The dev of this project had previously created another deflationary token BURN. When the Balancer Labs released the Balancer Protocol, he had an idea to combine the two, deflationary token and a pool of tokens, making the first deflationary index fund. It started in the end of May and on the 3rd iteration, May 29th - a trustless version was launched that we see today. As briefly explained earlier, STATERA or STA is an Index Deflationary Token built on Ethereum blockchain; Index: Contains a token suite of world class leading crypto assests BTC, ETH, LINK, SNX with STA. Deflationary: On every transaction of STA 1% of the transacted amount is sent to 0x address on ethereum, burned forever, thus reducing the circulating supply of STA Index+Deflationary: STA is mixed with BTC, ETH, LINK SNX in a portfolio, backed by liquidity on a protocol known as balancer (balancer.finance) This platform serves as a market maker for the token suit. The Index suite is of equal rate of 20%, that is 20% of BTC, ETH, SNX LINK and STA, Thus, anytime there is an increase in value of any of those coins or tokens, balancer automatically trade them for STA in order to keep the token suit ratio balanced. And anytime there is an increase in the value of STA, the same process applies. while doing this trade, it enables further burning on every transaction, thus facilitating more token scarcity. In addition to this, Statera was deployed with contract finalised, that is, the index suite can not be altered, It is completely out of Dev's control.
Q2 : What are the achievements that have been obtained by Statera in 2020? And what goals do you want to achieve in 2020?
By this we assume the questionnaire is asking for a roadmap! First, the project is barely a month old, and within just a month, our liquidity has grown from $50,000 to over $400,000 currently above $300,000. Among the things we have accomplished so far is the creation of market value for STA's Balancer liquidity pool token BPT, which is currently over $1000 per one BPT. Regarding what we set to achieve: The future is filled with many opportunities and potentials, currently, we are working on a massive campaign to introduce our product to the outside world. We have already made contact with different and reputable forums and channels regarding marketing and advertisement offers, some which we are currently negotiating, some which we are awaiting response. All we can say for now is that the Team is working hard to make this the Investment opportunity every crypto enthusiast has been waiting for. Statera has the goal of putting cryptocurrency into every portfolio. We believe we have a product that increases the returns of investing in cryptocurrencies and makes it easier to diversify in this space. We have done so much in June: articles, how to videos, completed the audit, tech upgrades like one token liquidity additions, and beginning our many social communities. We have been hard at work behind the scenes but things like sponsorships, features, and media take time, content makers need days if not weeks to develop content, especially the best of the best. We are working tirelessly, we will not disappoint. We have plans for 2020-2025 and will release those in the next month. They are big and bold, you’re going to be impressed by the scale of our vision, when we say “Cryptocurrency in every portfolio” we mean it. In 2020 more specifically we are focused on more media, videos, product offerings, and exchanges.
Q3 : What is the purpose of STA token? How can we get STA? The purpose of STA is an investment in the first deflationary index fund. The whole index's value rises from these aspects: 1. The index funds (WBTC,WETH,SNX,LINK) appreciate in value 2. When the index tokens are traded, the pool receives transaction fees - 1% 3. STA burns on transactions, so it's deflationary nature increases its value as the total supply drops 4. Balancer rewards Index holders with BAL token airdrops every week You can invest via the 'Trade' links in stateraproject.com website. Easiest way is to do it using ETH. The monetary policy of our token is set in stone and constantly deflationary. This negative supply pressure is a powerful mechanism in economics and price discovery. Through the lowering of supply we can decrease your beta (volatility) and increase your alpha (gains). Our token is currently only top 40 in liquidity on Balancer, however our volume is top 10! You want to know why? Because Statera works. Statera increases arbitrage, volume, fees, BAL rewards, and liquidity. Our liquidity miners in our Balancer pool are already making some of the highest BAL rewards on the platform, one user we spoke with made 18% in June, that’s over 150% APY! Our product is working, 100% (or you could say 150%), and when people start to see that, and realize the value, the sky's the limit.
Q4 : can we as a user do STA mining? The supply of STA doesn't increase anymore, it only decreases due to the burn feature. So there is no way to mine anymore STA. Only way to acquire the tokens is via an exchange. The monetary policy of our token is set in stone and constantly deflationary. This negative supply pressure is a powerful mechanism in economics and price discovery. Through the lowering of supply we can decrease your beta (volatility) and increase your alpha (gains). Our token is currently only top 40 in liquidity on Balancer, however our volume is top 10! You want to know why? Because Statera works. Statera increases arbitrage, volume, fees, BAL rewards, and liquidity. Our liquidity miners in our Balancer pool are already making some of the highest BAL rewards on the platform, one user we spoke with made 18% in June, that’s over 150% APY! Our product is working, 100% (or you could say 150%), and when people start to see that, and realize the value, the sky's the limit.
Q5 : The ecosystem of a public chain has a lot to do with the level of engagement and participation of third-party developers. How does Statera support the developers?
Not really. Our project is focusing on investment opportunities for the cryptocurrencies. The cryptocurrency tokens that are not used and are just sitting in a wallet can work for you by being added to an index fund and appreciate in value over time. First off, what we have created is a new asset class, I’ll repeat that, a new asset class. This asset has never existed: “Deflationary Index Fund,” what does that mean for finance? What will developers do with this? It’s hard to give a finite answer. We hope there are future economic papers on our token and what it means to be a deflationary index fund. With the addition of synthetic assets and oracles you can put any asset into the DeFi space: Gold, Nikkei 225, USD, etc. STA can be combined with any assets and bring the benefits of it’s ecosystem and deflationary mechanism to that asset. STA, the token itself, also gives you access to the price action of any asset it is paired with. Put simply STA’s balancer pool(s) give you a benefit in holding them, and STA’s price will reflect it’s inclusion in Balancer Pool(s) (and possibly future financial instruments), so STA is a bet on DeFi as a whole. When we say as whole, we mean as whole: what happens if you include STA in a crypto loan, or package it with a synthetic S&P 500 token, or use it as fee payment in a DeFi platform? Being fully decentralized it is up to our community to make this happen, social engagement and community are key. We are constantly bringing community members onto our team and rewarding those that benefit the ecosystem. in addition, Statera is a fully community project now. Paul who is the current team leader was an ordinary member of the community weeks ago, due to his interest and support for the project, he started dedicating his time to the project. Quite a number of community members are also in the same position, while Statera was developed by an individual, it is being built by the entire Statera community
Community Questions (Twitter):
Q1 From: @KazimKara35 The project tells us that the acquisition and sale of data between participants is protected by code of conduct and how safe is deployed on the blockchain, but how do you handle regulations while operating on a global scale?
Statera is decentralized token, similar to other utility crypto tokens and same regulations apply to it as others. his is actually a benefit of our decentralized nature. This isn’t legal advice, however in the past regulating bodies have ruled that the more decentralized a project is, especially from launch, the less likely they are to be deemed a security (see: Ethereum). This means they can be traded more freely and be available on more platforms. We are as decentralized as you can be. The data itself is all secured through the blockchain which has been shown to be a highly secure medium. We do not store any of your data and as long as you follow best practices in blockchain security there are no added security risks of using Statera. We don’t, and literally can’t, hold anymore personal information than is made available in any blockchain transaction. and that "personal information" is more likely than not just your ethereum wallet address, no "real world" data is included in transactions
Q2 from: @Michael_NGT353 What is Mechanism you use On your Project sir? Are you Use PoS,PoW or other Mechanism Can you explain why you use it and what is Make it Different?
Our token is an ERC-20 token and it's running on the Ethereum blockchain. The Ethereum's POW mechanism is currently supporting the Statera token We run on Ethereum, so we are currently PoW. With ETH 2.0 we will hopefully be PoS this year (hopefully). We use it because ETH has over 100 million addresses and around a million daily transactions. We are currently at about 1,900 token holders, we are just touching the edge of what is possible in this market. We chose the biggest and the best network available right now to launch our product. We think the upside is huge because of this choice. Being the biggest network it is also one of the most secure, no high risk vulnerabilities have been found in Ethereum or in our code (we've had our code audited by a third party, Hacken, and you can read their audit on our Medium page), so we also have security on our side
Q3 From : @Ryaaan_Nguyen Can you list some of Statera outstanding features for everyone here to know about? What are the products that Statera is focusing on developing?
As mentioned earlier by GC, First off, what we have created is a new asset class, I’ll repeat that, a new asset class. This asset has never existed: “Deflationary Index Fund,” what does that mean for finance? What will developers do with this? It’s hard to give a finite answer. We hope there are future economic papers on our token and what it means to be a deflationary index fund. With the addition of synthetic assets and oracles you can put any asset into the DeFi space: Gold, Nikkei 225, USD, etc. STA can be combined with any assets and bring the benefits of it’s ecosystem and deflationary mechanism to that asset. STA, the token itself, also gives you access to the price action of any asset it is paired with. Put simply STA’s balancer pool(s) give you a benefit in holding them, and STA’s price will reflect it’s inclusion in Balancer Pool(s) (and possibly future financial instruments), so STA is a bet on DeFi as a whole. When we say as whole, we mean as whole: what happens if you include STA in a crypto loan, or package it with a synthetic S&P 500 token, or use it as fee payment in a DeFi platform? We touched on this a bit in the question on what makes us special compared to other exchanges. We have created a product that synergizes with Balancer Pools creating a symbiotic relationship that improves the outcomes for users (our product can also synergize with future DeFi products). By including STA in an index fund with Link, BTC, ETH, and SNX you can buy one token and access the price action of four of the leading cryptocurrencies. You can also invest directly in the index fund (balancer pool) and receive the benefits of fees and BAL tokens paid to you while also having an automatically balanced portfolio (like an index fund with dividends). Lastly, the deflationary mechanics of STA increases the chance for positive price action while decreasing beta. We want to package Statera with assets across the whole cryptocurrency space, with an emphasis on DeFi. We also want everyday people to be able to invest quickly in crypto while also feeling reassured their investment is set up to succeed. We are focused on developing a name brand that people go to first and foremost when investing in crypto: cryptocurrency in every portfolio. This is all found in a smart contract that is fully decentralized, the founders can no longer augment the contract in any way and this has been confirmed by the third party code audit. This is a feature in and of itself, some argue that Bitcoin’s true value is in it’s network effect, first mover advantage, and immutability. Statera is modeled on all three of those and has those features in spades. The community now owns our token, the power in that, giving finance and power to the people, is why we are here.
Q4 From : @futcek What do you think about the possibility of creating new use cases in DeFi space for existing real world assets by using crypto technology? What role do you see in this creation for Statera?
I think my answer above actually answers this perfectly, Statera in and of itself is a “new use case”, a “deflationary index fund” has never existed, I’ll copy and paste the other relevant part: “With the addition of synthetic assets and oracles you can put any asset into the DeFi space: Gold, Nikkei 225, USD, etc. STA can be combined with any assets and bring the benefits of it’s ecosystem and deflationary mechanism to that asset. STA, the token itself, also gives you access to the price action of any asset it is paired with.

Being fully decentralized it is up to our community to make this happen, social engagement and community are key. We are constantly bringing community members onto our team and rewarding those that benefit the ecosystem.” Statera is a way to make your investment more successful, and owning Statera let's you benefit from other people using it to make their investments more successful (a self feeding cycle).
Q5 From : @Carmenzamorag Statera's deflationary system is based in that with every transaction 1% of the amount is destroyed, would this lead to lack of supply and liquidity in the long term future? How would that be fixed?
The curve of supply is asymptote, meaning that it will never reach zero. The idea is that the deflationary process will slowly decrease the supply of STA, which – combined with a fixed or increaseing demand – will result in STA appreciating in value. Evidently, as the STA token increases in value, the amounts of STA being traded will slowly decrease: The typical investor might buy 10.000 STA at the current rate, but in the future (proportional to an increase in the valueation of STA) this number will tend to decrease, hence the future investor might only buy 1000 STA. This of course results in less STA being burned. Additionally, STA is divisible to the 18th decimal, why – even if the supply was to reach 1 STA – there would be a sufficient supply. Well this would be a question for a Mathematician, and luckily we’re loaded with them (as seen above)! I’ll try to illustrate with an example. 1% of 100 million is 1 million, 1% of 10 million is 100,000. As we go down in supply the burn is less by volume. What also happens at lower supply is higher prices (supply and demand economics). So those 1 million tokens burned may be worth $20,000, but by the time overall supply is at 10 million those 100,000 tokens may also be worth $20,000 or even more. This means you transact “less”, if you want to buy 1 Ether now with Statera you need 8,900 STA which would burn 89 tokens. If Statera is worth $100 you only need 2.32 statera (.023 tokens burned). Along with this proportional and relative burn decrease, tokens are 18 decimals long, so even when we get to 1 token left (which mathematically would take decades if not centuries, but that is wholly dependent on usage), you are still left with 10 to the 18th power, or one quintillion “tokens”. So it’s going to take us a while to have supply issues :)
Nuked Phase (3rd Part)
Q) What is your VISION and Mission?
Our working mission and vision: Mission: Provide every investor with simple and effective ways to invest in cryptocurrency. Decrease volatility and increase positive price pressure in cryptocurrency investments. Lower the barrier to entry for more advanced investment tools. Be a community focused and community driven cryptocurrency, fully decentralized by every meaning of the word. Vision: We aspire to put “cryptocurrency in every portfolio”. We envision a world where finance is given back to the people and wealth building strategies withheld only for affluent individuals are given to all. We also strive to create an investment environment based on sound monetary policy and all the power that comes with a sound asset.
Q) What are the benefits of STA for its investors in long term? Does STA have Afrika as an important area for its expansion?
We have ties to Africa and see Statera as a way for anyone and everyone to invest in cryptocurrency. The small marketcap of statera makes it's price low and it's upside massive. Right now if you wanted to be exposed to the price action of four cryptocurrencies (BTC, ETH, Link, SNX) Statera is a way to gain that exposure in a way that has a huge upside, compared to the other four assets, there are risks in investing in any small cap but with those risk come outsized rewards (not investment advice and all answers are solely my opinions 😊)
Q) In the long run, why should we trust and follow STATERA? How do you raise awareness and elimination of the doubts of investors / partners / customers?.
You're really asking "How do I trust myself and other crypto investors" The project is FULLY decentralized, it is now in the hands of the community. We would venture a guess that the community wants their investment to succeed and be worth more in the future, so you are betting on people. wanting to make themselves money on their own investment. This is a pretty sure bet. The community being active and engaged is key, and we have short term and long term plans to ensure this happens
Q) No one can doubt the strength of #Statera. But can you tell us some of the challenges and difficulties you're presently facing? How can you possibly overcome them?
We're swinging outside our weightclass, we don't see litecoin or SNX, or any other crypto product as our competition. Our competition is NASDAQ, Fidelity, etc. We want to provide world class financial instruments that only the wealthy have access to in the traditional world to everyone. Providing liquidity, risk parity, being paid to provide liquidity, unique value propositions, are all things we want to bring to everyone. However we are coming up in a hectic space, everyday their is fud and defamation on the web, but that is the sandbox we chose to play in and we aren't grabbing our ball and going home. We can tell you that we will not disappoint and fighting all the fud that comes along with being a small and upstart project only fuel our fire. Building legitimacy is our largest challenge and looking at our audit, financial report, and some things you will see in the coming weeks, we hope you see we are facing those challenges head on.
Q) What is the actual uniqueness of #Statera.??? Can you guys please explain tha advantages of #Statera over other projects.??
When we launched there were no other products like ours. There are now copies, and we wish them the best, but we have the best product, hands down. Over the next couple weeks this will become apparent, if it hasn't already, also a lot of the AMA answers dug deeper into our unique value proposition, especially the benefits we provide to Balancer Pools which shows the benefits we would provide for any index fund. We are a tool to improve cryptocurrency investing
Q) Fragmentation, layering and cross-chain are three future solutions for high-performance blockchains. Where is Statera currently? What are the main reasons for taking this direction?
We operate on the Ethereum chain, as it upgrades our services and usability will upgrade. We are working on UI and more user friendly systems to onboard people into our ecosystem
Q) How STATERA plan to make room and make this project known in the world of crypto, full of technology and full of new projects very good in today's market?
We think we have a truly innovative product, which - when first understood - appeals to most investors. Whether you want a high-volatility/medium-risk token like STA or whether you are more conservative and simply just plan on adding to the Statera pool BPT (which is not nearly as volatile but still offers great returns). We plan on making Statera known to the crypto world through a marketing campaign which slowly will be unravelled in the comming days and weeks. If interested, you can check out an analysis of the different investment options in the Statera ecosystem in our first financial report: https://medium.com/@stateraproject/statera-financial-reports-b47defb58a18
Q) Hello, cryptocurrencies are very volatile and follow bitcoin ... and does this apply to Statera? or is there some other logic present in some way? is statera token different from a current token? Are you working on listings on other exchanges?
Currently uniswap is somewhat uncomfortable for fees. We are also on bamboo relay, saturn network, and mesa. Statera will be volatile like all cryptocurrency, this is a small and nascent space. But with the deflationary mechanic and balancer pool, over time, as marketcap grows it will become less volatile and more positively reactive to price.
Q) Security is one of the most essential characteristics for a project to get reputation. How can #Statera Team assure to their community that users assets and investments will stay safe from unwanted agents?
We have been third party audited by the same company that worked with VeChain to audit their code. Our code has been shown to be bulletproof. Unless Ethereum comes up with a fatal security flaw there is nothing that can happen to our contract (there is no backdoor, no way for anyone to edit or adjust the smart contract).
Q) Many investors see the project from the price of the coin. Can you give us advantages why Statera is so suitable for long-term investment? and what makes Statera different from other similar projects?
Sometimes the simplest solutions are the most effective. A question you can ask is “What if this fails”? But you can also ask, “What if this succeeds”? Cryptocurrency is filled with asymmetric risks, we think if you look into the value proposition you will find that there is a huge asymmetric risk/reward in Statera, and we will make that even clearer in our soon to be released litepaper. You are on the ground floor of a simple but highly effective solution to onboarding people into defi, cryptocurrencies, and investing. Our product reduces volatility and increases gains (decreases beta and increases alpha in investor terms), which is highly attractive in any investment. The down side is there but the upside outweighs it exponentially (asymmetric risk)
Q) What your plans in place for global expansion, are Statera focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships? Can you explain this?
We have reached out to influencers in other countries and things are in the works. We have also translated documents and are working on having them in at least 4 languages by the end of July. We were founded globally, our team is global, and we are focused on reaching all 7 billion people.
Q) Now in the cryptofield everyday there are new projects joining in the Blockchain space. They are upgraded, Well-established and coming up with innovative technology. How Statera going to compete with them? What do you think, one day Statera will become useless And will be lost into the abyss of time for not bringing any new technology?
We are the first of our kind, no one had a deflationary index fund before us. Index funds will be the future of crypto (look at the popularity of etfs and indexes in the traditional markets). We are a tool to make your index function better and pay you more. As long as people care about crypto index funds they will care about the value STA brings to that. We have an involved and long term plan to reach dominance over a 5 year span, this is not a flash in the pan, big things coming
Q1. You say that the weight and proportions of your tokens are constant. So how have you managed to prevent market price speculation from generating hypervolability in your token price? Do you consider yourselves a kind of stablecoin? Q2. How many jurisdictions allow the use of Stratera products and services? Are they available for Latin America? @joloroeowo The balancer ensures an equal ratio of 20% amongst the five tokens included in our fund. This, however, does not imply that the tokens are stable. Rather, the Balancer protocol helps mitigating price fluctuations.
Q) How can I as a Statera participant participate in liquidity mining, and receive BAL as reward? What are the use cases of $STA token, and how are users motivated to buy and hold long term?
The easiest way is to go to stateratoken.com and click trade then BPT. You can also buy all five tokens and click on portfolio then add liquidity. Balancer is working on a simpler interface to add liquidity with one token, we are waiting on them. I think we explained the use cases above
Q) What do you plan have for global expansion, is Statera currently focused solely on the market? Or is it focused on building and developing or acquiring customer and user or partnership relationships? Can you explain it?
We are currently working on promoting the project and further develope our product, making it lucrative for more new investors to join our pool and invest in the STA token.
Q1) Statera have 2 types of tokens, so can you tell me the differences between STA and STAC ? What are their uses cases? Is possible Swap between them? Q2) Currently the only possible Swap or "exchange" possible is Uniswap, so you do have plans to list the STA token into a more Exchanges?
STAC is obsolete, we only have STA and BPT (go to our website and click on trade) stateratoken.com BPT gives you more diversification and less risk, STA gives you more volatility and more chance for big gains. Q2 we are on multiple exchanges (4), bamboo relay, saturn, and mesa we do have plans for future exchanges but the big ones have processes and hoops to jump through that can't be done so quickly
Q) What business scenarios can STATERA support now? In which industries can we see the mass adoption of STATERA technology in the near future?
Statera increases the effectiveness of your cryptocurrency investments. Specifically it makes cryptocurrency index funds function better, netting you higher returns, which we have already seen in just one month of implementation. Right now, today, you can buy our BPT token and increase the functionality of holding a crypto index fund. In the future we want every single web user to see and use our product
Q) Do you plan to migrate to other platforms like Tron, BinanceChain, EOS, etc. if it is feasible??
Migrating our current contract is not. Starting new offerings on those other chains could be possible, they aren't on our radar currently but if the community requests them we are driven by our community
Q) ETH Blockchain is a Blockchain have many token based in it, i have used ETH blockchain long time and i see it have big fee and need much time to make a transcation so Why you choose to based STA in ETH blockchain not other like Bep2 or Trc20 ?
Simply: 100 million addresses, 1 million transactions a day. The more users we have the more we will benefit our community. We hope ETH 2.0 scaling will fix the problems you mention.
Q) No one achieve anything of value on its own, please can you share about Statera present and future partnerships that will drive you to success in this highly congested crypto space?
We have a unique product that no one else has (there are people who have copied us). We can't announce our current and future partnerships yet, but they will be released soon. Our future hopes of partnerships are big and will be key to our future, know we are focused on making big partnerships, some you may not even be thinking about.
Q) According to the fact that your algorithm causes 1% of each transaction to be destroyed, I would like to know, then, how you plan to finance yourself as a project in the long term?
The project is now in the hands of the community and we are a team of passionate people volunteering to help promote and develope the Statera ecosystem. But then, how do we afford running a promo campaign? We have lots of great community members donating funds that goes to promoting the project. In other words, the community helps financing the project. And so far, we have created a fantastic community consisting of passionate and well-educated people!
Q) There are many cryptocurrency startups were established by talent teams, but they got problem in raising capital via token sales due to many factors as bear market, bankrupt etc. This leaded their potential startups fail. So how will Statera break these barriers and attract more funds from outside crypto space?
We are community focused and community ran. When you look at centralized cryptocurrencies you can see the negative of them (Tron, ADA, etc.) We believe being fully decentralized is the true power position. You the owner of statera can affect our future and must affect our future. This direct ownership means people need to mobilize and organize to push us forward, and it is in their best self interest to do so. It's a bet on our community, we're excited about that bet
Q) What business scenarios can STATERA support now? In which industries can we see the mass adoption of STATERA technology in the near future?
Statera increases the effectiveness of your cryptocurrency investments. Specifically it makes cryptocurrency index funds function better, netting you higher returns, which we have already seen in just one month of implementation. Right now, today, you can buy our BPT token and increase the functionality of holding a crypto index fund. In the future we want every single web user to see and use our product
Q) Why being a hybrid of a liquidity pool and an index fund? What are the main benefits about this?
By being a liquidity pool the exchange side of the pool (balancer also functions as an exchange) gives you added liquidity for more effortless, effective, and cheaper rebalancing. You also benefit from getting paid the fee when people use the exchange AND getting paid BAL tokens that are worth $15-20 USD. These are not benefits you get with an index fund, meanwhile the liquidity pool rebalances just like an index fund would
Q) Which specific about technology and strategy of #STA that make you believe it will be successful and what does #STA plan do to attract more users in the upcoming time?
I think the idea behind Statera is truly ingenious. We have made an index fund, which investors are highly(!) incentivised to invest in, namely because the ROI, so far, has been huge. An increase in the pool liquidity (index fund) indirectly translates into an increase in the price of STA, why we think the STA token - combined with its deflationary nature - will increase in the long run. The mechanism behind this is somewhat complex, but to better get an understanding of it, I suggest you visit our medium page and read more about the project: https://medium.com/@stateraproject

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

I originally posted this on cryptocurrency. I just thought you guys might be able to help as well so I posted it as well. I didn't link to the original post because the bot here keeps deleting my post, even if I use the np link. Hope that's ok...
EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors.
TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [[email protected]](mailto:[email protected]) . Thanks in advance!
Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.
The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract.
The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data.
The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block.
To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block.
I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors.
The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract.
There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive).
The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only.
I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport.
When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software.
The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create:
  1. A logistic and transportation company
  2. A delivery company
  3. A company that buy and sell real estate options
  4. A company that manage real estate
  5. A software development company
  6. A world-wide fiat money transfer company
  7. A payment processor company
We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money.
We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche.
I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper.
If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [[email protected]](mailto:[email protected]) .
If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed.
Thanks all in advance!
P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

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!

Ethereum 2.0: Why, How And Then?

Ethereum 2.0: Why, How And Then?
Why update Ethereum? One problem of the Ethereum network that the update should solve is scalability. At the moment, its blockchain can perform to 15 transactions per second, which is over two times more than that of bitcoin. However, this speed is still not enough for a large number of users. For example, the Visa payment system can perform up to 24 thousand transactions per second.
Adding an Optimistic Rollup technology will help to solve the scalability problem. According to Vitalik Buterin, the creator of Ethereum, its implementation will occur after the network’s update and will increase its throughput to 1000 transactions per second.
by StealthEX
Another solution to this problem is a change in the algorithm. Currently, Ethereum runs on the same protocol as Bitcoin, Proof-of-Work, confirmation of transactions in the cryptocurrency network occurs using the computing power of processors.
Using the Proof-of-Work algorithm limits the growth of the Ethereum network bandwidth. To withstand a large load, more miners are needed, but the growth of their number slows down since it becomes more difficult to mine cryptocurrency and, consequently, less profitable.
This is the reason the Ethereum development team is planning to switch to the Proof-of-Stake algorithm. Unlike the PoW, it does not require the use of computing power to confirm blocks. Instead of miners, transactions will be confirmed by validators. To become a validator, the user should have 32 ETH and install a special client. From a technical point of view, this is easier than buying mining devices and maintaining their functionality, as well as looking for access to cheap electricity. Thus, the system will no longer need expensive hardware.
The main solution to the scalability problem will be to implement sharding. Current Ethereum network is a unified database. After the update, the blockchain will be divided into autonomous, interacting blocks — shards, each of which will process particular transactions and smart contracts, which, however, will be recognized by the entire Ethereum blockchain. Nodes that form the shard process information separately, this allows maintaining the principle of decentralization. This is important since the risk of centralization is another big problem of the old algorithm.
Since the complexity of mining has increased over time, and now this process requires having expensive equipment and access to cheap electricity, small participants can not afford to stay in the game. In such conditions, big pools of miners that can provide higher productivity have a decisive advantage. For example, in April, more than 50% of the computing power of the Ethereum network was provided by only two mining pools. This creates a significant risk of centralization and “51% attacks”.
Validators will confirm transactions and get rewards in the form of passive income. According to the project’s roadmap, this amount will vary from 1.81% to 18.1%. The profitability of the stacking will depend on the number of validators. The more of them, the smaller the amount they get. However, there will be some costs. In the same Ethereum 2.0 roadmap, developers mentioned that the cost of validating transactions, based on rough calculations, will be about $180 per year. One of the developers of the project, Justin Drake, predicts that on average the validator will receive an income of 5% per year.

What is the estimated Ethereum 2.0 release date?

The launch of Ethereum 2.0 will take place gradually, in six stages, the “zero” of which is expected this summer. However, it is worth noting that due to finding vulnerabilities, the dates have already been shifted several times–initially, the transition to the new version was planned in 2019.
One of the developers of the project, Afri Schoedon, said that the launch could be postponed to 2021. According to him, under favourable circumstances, the main network can be presented in November of this year, but there are certain difficulties in this.
Schoedon explained that before launching ETH 2.0, all of its clients must be brought to the same specifications. After that, the developer’s team needs to open a unified deposit contract so that users can transfer their assets from the old chain to the new one. Between these stages, developers also need additional time, so they could test all aspects of the new system.
As it usually happens, there’s going to be two parallel blockchains as a result of the hard fork. The first one, ETH1, will continue to work using an old protocol, while the update will be implemented on ETH2. Users will be able to transfer their coins from the old blockchain to the new one, but not vice versa. The appearance of sharding will allow developers to move to phase 1.5 — during this phase, ETH1 will merge with ETH2, becoming one of the 64 “shards” of the updated blockchain. In the second phase, smart contracts become available on ETH2, which can be considered the full start of its economic activity.

And what are expectations?

Updating the Ethereum network will increase its technical capabilities, namely, it will speed up and reduce the cost of transactions, as well as make the blockchain less vulnerable for centralization process.
Currently, the absolute majority of decentralized finance projects are developed using the Ethereum platform. The Ethereum 2.0 release will probably attract even more partners who will use the blockchain for their projects.
Ryan Watkins, Messari Analysis company’s researcher, highly values the importance of updating.
“ETH 2.0 is a much stronger catalyst than the Bitcoin halving simply because it’s an uncertain and fundamental change.” — Ryan Watkins wrote on his Twitter account
And the part about uncertainty is hard to disagree with. Of course, there are some concerns about the bright Ethereum future. The coming hard fork carries with it potential negative consequences. For example, after switching to the PoS algorithm, the US Securities and Exchange Commission (SEC) may well admit Ethereum as a security, which will lead to legal complications similar to those faced by Pavel Durov when trying to launch his TON blockchain platform.
For now, ETH is the most popular coin for mining at home, and most of these miners will probably just leave the network.
There is also a risk that the price of Ethereum may fall. To receive passive income for storing ETH, the user will not only need to have 32 coins but also block them through a special transaction. They will not be able to withdraw these blocked funds immediately. As stated in the project roadmap, the cryptocurrency withdrawal process will take at least 18 hours. This could take even more time if many users request the return of tokens at the same time. Thus, if ETH falls in price, it will be impossible to sell it immediately, and there is a risk of losing some capital and all the income received from stacking.
Nevertheless, investors are mostly optimistic — the volume of Ethereum options on the Deribit exchange has grown to a historical high, which indicates confidence in the future of Ethereum project. The ETH price is also growing, having overcome the consequences of the March collapse of cryptocurrencies.
Most experts agree that Ethereum price will grow after the update. On the one hand, the altcoin will become more expensive, as it will become a more attractive investment. On the other hand, the offer will decrease, as users will start transferring coins from the first version of the network to the second, to block them for passive income.
