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!

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. 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.” 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

Zano Newcomers Introduction/FAQ - please read!

Welcome to the Zano Sticky Introduction/FAQ!

https://preview.redd.it/al1gy9t9v9q51.png?width=424&format=png&auto=webp&s=b29a60402d30576a4fd95f592b392fae202026ca
Hopefully any questions you have will be answered by the resources below, but if you have additional questions feel free to ask them in the comments. If you're quite technically-minded, the Zano whitepaper gives a thorough overview of Zano's design and its main features.
So, what is Zano? In brief, Zano is a project started by the original developers of CryptoNote. Coins with market caps totalling well over a billion dollars (Monero, Haven, Loki and countless others) run upon the codebase they created. Zano is a continuation of their efforts to create the "perfect money", and brings a wealth of enhancements to their original CryptoNote code.
Development happens at a lightning pace, as the Github activity shows, but Zano is still very much a work-in-progress. Let's cut right to it:
Here's why you should pay attention to Zano over the next 12-18 months. Quoting from a recent update:
Anton Sokolov has recently joined the Zano team. ... For the last months Anton has been working on theoretical work dedicated to log-size ring signatures. These signatures theoretically allows for a logarithmic relationship between the number of decoys and the size/performance of transactions. This means that we can set mixins at a level from up to 1000, keeping the reasonable size and processing speed of transactions. This will take Zano’s privacy to a whole new level, and we believe this technology will turn out to be groundbreaking!
If successful, this scheme will make Zano the most private, powerful and performant CryptoNote implementation on the planet. Bar none. A quantum leap in privacy with a minimal increase in resource usage. And if there's one team capable of pulling it off, it's this one.

What else makes Zano special?

You mean aside from having "the Godfather of CryptoNote" as the project lead? ;) Actually, the calibre of the developers/researchers at Zano probably is the project's single greatest strength. Drawing on years of experience, they've made careful design choices, optimizing performance with an asynchronous core architecture, and flexibility and extensibility with a modular code structure. This means that the developers are able to build and iterate fast, refining features and adding new ones at a rate that makes bigger and better-funded teams look sluggish at best.
Zano also has some unique features that set it apart from similar projects:
Privacy Firstly, if you're familiar with CryptoNote you won't be surprised that Zano transactions are private. The perfect money is fungible, and therefore must be untraceable. Bitcoin, for the most part, does little to hide your transaction data from unscrupulous observers. With Zano, privacy is the default.
The untraceability and unlinkability of Zano transactions come from its use of ring signatures and stealth addresses. What this means is that no outside observer is able to tell if two transactions were sent to the same address, and for each transaction there is a set of possible senders that make it impossible to determine who the real sender is.
Hybrid PoW-PoS consensus mechanism Zano achieves an optimal level of security by utilizing both Proof of Work and Proof of Stake for consensus. By combining the two systems, it mitigates their individual vulnerabilities (see 51% attack and "nothing at stake" problem). For an attack on Zano to have even a remote chance of success the attacker would have to obtain not only a majority of hashing power, but also a majority of the coins involved in staking. The system and its design considerations are discussed at length in the whitepaper.
Aliases Here's a stealth address: ZxDdULdxC7NRFYhCGdxkcTZoEGQoqvbZqcDHj5a7Gad8Y8wZKAGZZmVCUf9AvSPNMK68L8r8JfAfxP4z1GcFQVCS2Jb9wVzoe. I have a hard enough time remembering my phone number. Fortunately, Zano has an alias system that lets you register an address to a human-readable name. (@orsonj if you want to anonymously buy me a coffee)
Multisig
Multisignature (multisig) refers to requiring multiple keys to authorize a Zano transaction. It has a number of applications, such as dividing up responsibility for a single Zano wallet among multiple parties, or creating backups where loss of a single seed doesn't lead to loss of the wallet.
Multisig and escrow are key components of the planned Decentralized Marketplace (see below), so consideration was given to each of them from the design stages. Thus Zano's multisig, rather than being tagged on at the wallet-level as an afterthought, is part of its its core architecture being incorporated at the protocol level. This base-layer integration means months won't be spent in the future on complicated refactoring efforts in order to integrate multisig into a codebase that wasn't designed for it. Plus, it makes it far easier for third-party developers to include multisig (implemented correctly) in any Zano wallets and applications they create in the future.
(Double Deposit MAD) Escrow
With Zano's escrow service you can create fully customizable p2p contracts that are designed to, once signed by participants, enforce adherence to their conditions in such a way that no trusted third-party escrow agent is required.

The Particl project, aside from a couple of minor differences, uses an escrow scheme that works the same way, so I've borrowed the term they coined ("Double Deposit MAD Escrow") as I think it describes the scheme perfectly. The system requires participants to make additional deposits, which they will forfeit if there is any attempt to act in a way that breaches the terms of the contract. Full details can be found in the Escrow section of the whitepaper.
The usefulness of multisig and the escrow system may not seem obvious at first, but as mentioned before they'll form the backbone of Zano's Decentralized Marketplace service (described in the next section).

What does the future hold for Zano?

The planned upgrade to Zano's privacy, mentioned at the start, is obviously one of the most exciting things the team is working on, but it's not the only thing.
Zano Roadmap
Decentralized Marketplace
From the beginning, the Zano team's goal has been to create the perfect money. And money can't just be some vehicle for speculative investment, money must be used. To that end, the team have created a set of tools to make it as simple as possible for Zano to be integrated into eCommerce platforms. Zano's API’s and plugins are easy to use, allowing even those with very little coding experience to use them in their E-commerce-related ventures. The culmination of this effort will be a full Decentralized Anonymous Marketplace built on top of the Zano blockchain. Rather than being accessed via the wallet, it will act more as a service - Marketplace as a Service (MAAS) - for anyone who wishes to use it. The inclusion of a simple "snippet" of code into a website is all that's needed to become part a global decentralized, trustless and private E-commerce network.
Atomic Swaps
Just as Zano's marketplace will allow you to transact without needing to trust your counterparty, atomic swaps will let you to easily convert between Zano and other cyryptocurrencies without having to trust a third-party service such as a centralized exchange. On top of that, it will also lead to the way to Zano's inclusion in the many decentralized exchange (DEX) services that have emerged in recent years.

Where can I buy Zano?

Zano's currently listed on the following exchanges:
https://coinmarketcap.com/currencies/zano/markets/
It goes without saying, neither I nor the Zano team work for any of the exchanges or can vouch for their reliability. Use at your own risk and never leave coins on a centralized exchange for longer than necessary. Your keys, your coins!
If you have any old graphics cards lying around(both AMD & NVIDIA), then Zano is also mineable through its unique ProgPowZ algorithm. Here's a guide on how to get started.
Once you have some Zano, you can safely store it in one of the desktop or mobile wallets (available for all major platforms).

How can I support Zano?

Zano has no marketing department, which is why this post has been written by some guy and not the "Chief Growth Engineer @ Zano Enterprises". The hard part is already done: there's a team of world class developers and researchers gathered here. But, at least at the current prices, the team's funds are enough to cover the cost of development and little more. So the job of publicizing the project falls to the community. If you have any experience in community building/growth hacking at another cryptocurrency or open source project, or if you're a Zano holder who would like to ensure the project's long-term success by helping to spread the word, then send me a pm. We need to get organized.
Researchers and developers are also very welcome. Working at the cutting edge of mathematics and cryptography means Zano provides challenging and rewarding work for anyone in those fields. Please contact the project's Community Manager u/Jed_T if you're interested in joining the team.

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!

What Is Proof of Work (PoW)?

What Is Proof of Work (PoW)?
Contents

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

What is a double-spend?

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

Why is Proof of Work necessary?

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

How does PoW work?

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

Proof of Work vs. Proof of Stake

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

Closing thoughts

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

Gulden [NLG] - Constant development - In wallet Staking/Mining/Dex

Official Website / Official Slack
About Gulden:
How to setup a Witness (Staking) Gulden was founded in April 2014 based on the Litecoin codebase. In 2015 the Litecoin codebase is abandoned and Gulden switched to the Bitcoin codebase. After years of development it can be said that Gulden now has its own codebase. Gulden started with a 10% premine that was spent entirely on development. The current developments are now paid by part of the mining reward. The direction of the developments are determined by the Gulden advisory board (GAB). The GAB consists of 9 members and is elected each year from the members of the community. Anyone can stand for election. Voting for candidates is recorded and done through the Gulden blockchain. Gulden would like to become a generally accepted means of payment. To this end, the development is aimed at making the wallets as user-friendly as possible.
What makes Gulden unique:
- PoW2 - Proof of work + Witness/Staking - SegSig (Segregated Signature) - SIGMA (Semi Iterated Global Memory Argon) - Linking (Control your mobile wallet from your desktop wallet) - Wallet accounts - Unity (Unified codebase) - Delta (Difficulty Algorithm) - Sonic (Fast Sync)
Features of Gulden explained:
PoW2: Gulden does not use a standard PoW consensus model, but the in-house developed PoW2 model. This is a combination of PoW and Witness. Miners control the transactions and the Witness controls the miners. In order to get the same chance of success for a double spend as for the single transaction approval systems it is therefore necessary not to control >50% of the mining power or >50% of the number of coins in witness accounts but to own more than 71% of both systems. (0.71 * 0.71 = 0.5 so 50% chance).
Because many Gulden owners have their Gulden fixed in witness, it is difficult to get a 71% majority in witness. There are now more than 100 million Gulden in witness. In order to get a 71% majority, an attacker has to secure an additional 220 million Gulden in witness. Apart from the fact that this is almost impossible, the price of the Gulden would go up sky high if so much Gulden had to be bought by the attacker. And because the attacker has to lock the Gulden, it looks like a bank robber who is going to rob his own bank. So such an attack is theoretically possible, but not possible in reality.
Anyone can become a witness: by locking an amount of Gulden in a Witness account in the desktop wallet for a certain amount of time. Depending on the weighting of the witness account (chosen duration and amount in the account) the witness earns rewards. The advantage of this system is that the Gulden blockchain can withstand 51% attacks without relying heavily on energy-guzzling PoW miners or vulnerable standard PoS systems. Transactions can be safely accepted after one confirmation instead of the standard 3-6 confirmations.

  1. PoW2 Whitepaper simply explained PoW² explored — A post-launch look at some of the security implications How to setup a Witness
SIGMA: Since October 17, 2019, the Gulden team has implemented the Sigma algorithm and since then it is possible to mine Gulden solo without additional equipment. The algorithm is asic resistant and can be done on a normal desktop computer using it’s CPU. One can simply use this CPU mining algorithm by creating a mining account in the desktop wallet and start mining Gulden.
SegSig - Segregated Signature - Detailed article still to be published but was implemented with PoW2. Advantages of Segregated Signature: 1. 58% space saving on all transactions. More then twice the bitcoin SegWit implementation. 2. 58% increased transaction throughput. No block size or frequency changes needed. 3. Overhaul to the transaction script system which allowed us to implement PoW² and SegSig as clean as possible along with other benefits.

Please take your time and read the technicals on this coin as its truly phenomenal and seriously under valorised and recognised. Barely any effort has been made to market its potential but you can judge yourself. Read the PoW2 Whitepaper or the short version PoW2 simply explained

How does cryptocurrency works?

How does cryptocurrency works?
When we were a much smaller society, people could trade in the community pretty easily, but as the distance in our trade grew, we ended up inventing institutions such as banks, markets, stocks etc. that help us to conduct financial transactions. The currencies we are operating with nowadays are bills or coins, controlled by a centralized authority and tracked by previously mentioned financial institutions. The thing is, having a third party in our money transactions is not always what we wish for. But fortunately, today we have a tool that allows us to make fast and save financial transactions without any middlemen, it has no central authority and it is regulated by math. Sounds cool, right? Cryptocurrency is this tool. It is quite a peculiar system, so let’s take a closer look at it.
by StealthEX

Layers of a crypto-cake

Layer 1: Blockchain

First of all – any cryptocurrency is based on the blockchain. In simple words, blockchain is a kind of a database. It stores information in batches, called blocks that are linked together in a chronological way. As the blockchain is not located in one place but rather on thousands of computers around the globe, the blockchain and the transactions thus are decentralized, they have no head center. The newest blocks of transaction are continuously added on (or changed) to all the previous blocks. That’s how you get a cryptocurrency blockchain.
The technology’s name is a compound of the words “block” and “chain”, as the “blocks” of information are linked together in a “chain”. That’s how crypto security works – the information in the recently created block depends on the previous one. It means that no block can be changed without affecting the others, this system prevents a blockchain from being hacked.
There are 2 kinds of blockchain: private and public. Public, as goes by its name, is publicly available blockchain, whereas private blockchain is permissioned, which only a limited number of people have access to.

Layer 2: Transaction

In fact, everything begins with the intention of someone to complete a transaction. A transaction itself is a file that consists of the sender’s and recipient’s public keys (wallet addresses) and the amount of coins transferred. The sender begins by logging in into his cryptocurrency wallet with the private key – a unique combination of letters and numbers, something you would call a personal password in a bank. Now the transaction is signed and the first step which is called basic public key cryptography is completed.
Then the signed (encrypted) transaction is shared with everyone in the cryptocurrency network, meaning it gets to every other peer. We should mention that the transaction is firstly queued up to be added to the public ledger. Then, when it’s broadcasted to the public ledger, all the computers add a new transaction to a shared list of recent transactions, known as blocks.
Having a ledger forces everyone to “play fair” and reduce the risk of spending extra. The numbers of transactions are publicly available, but the information about senders and receivers is encrypted. Each transaction holds on to a unique set of keys. Whoever owns a set of keys, owns the amount of cryptocurrency associated with those keys (just like whoever owns a bank account owns the money in it). This is how peer-to-peer technology works.

Layer 3: Mining

Now let’s talk about mining. Once confirmed, the transaction is forever captured into the blockchain history**.** The verification of the block is done by Cryptocurrency Miners – they verify and then add blocks to the public ledger. To verify them, miners go down on the road of solving a very difficult math puzzle using powerful software, which is that the computer needs to produce the correct sequence number – “hash” – that is specific to the given block, there is not much chance of finding it. Whoever solves the puzzle first, gets the opportunity to officially add a block of transactions to the ledger and get fresh and new coins as reward. The reward is given in whatever cryptocurrency’s blockchain miners are operating into. For example, BTC originally used to reward miners in 50 BTC, but after the first halving it decreased to 25 BTC, and at present time it is 6.25 BTC. The process of miners competing against each other in order to complete the transactions on the network and get rewarded is known as the Proof-of-Work (PoW) algorithm, which is natural for BTC and many other cryptocurrencies. Also there are another consensus mechanisms: Proof-of-Stake (PoS), Delegated Proof-of-Stake (dPoS), Proof-of-Authority (PoA), Byzantine Fault Tolerance (BFT), Practical Byzantine Fault Tolerance (pBFT), Federated Byzantine Agreement (FBA) and Delegated Byzantine Fault Tolerance (dBFT). Still, all of them are used to facilitate an agreement between network participants.
The way that system works – when many computers try to verify a block – guarantees that no computer is going to monopolize a cryptocurrency market. To ensure the competition stays fair, the puzzle becomes harder as more computers join in. Summing it up, let’s say that mining is responsible for two aspects of the crypto mechanism: producing the proof and allowing more coins to enter circulation.

Types of cryptocurrency

In the virtual currency world there are a bunch of different cryptocurrency types with their own distinctive features.
The first cryptocurrency is, of course, Bitcoin. Bitcoin is the first crypto coin ever created and used. BTC is the most liquid cryptocurrency in the market and has the highest market cap among all the cryptocurrencies.

Altcoins

The term ‘altcoins’ means ‘alternatives’ of Bitcoin. The first altcoin Namecoin was created in 2011 and later on hundreds of them appeared in crypto-world, among them are Ravencoin, Dogecoin, Litecoin, Syscoin etc. Altcoins were initially launched with a purpose to overcome Bitcoin’s weak points and become upgraded substitutes of Bitcoin. Altcoins usually stand an independent blockchain and have their own miners and wallets. Some altcoins actually have boosted features yet none of them gained popularity akin to Bitcoin. More about altcoins in our article.

Tokens

Token is a unit of account that is used to represent the digital balance of an asset. Basically tokens represent an asset or utility that usually are made on another blockchain. Tokens are registered in a database based on blockchain technology, and they are accessed through special applications using electronic signature schemes.
Tokens and cryptocurrencies are not the same thing. Let’s explain it more detailed:
• First of all, unlike cryptocurrencies, tokens can be issued and managed both centralized and decentralized.
• The verification of the token transactions can be conducted both centralized and decentralized, when cryptocurrencies’ verification is only decentralized.
• Tokens do not necessarily run their own blockchain, but for cryptocurrencies having their own blockchain is compulsory.
• Tokens’ prices can be affected by a vast range of factors such as demand and supply, tokens’ additional emission, or binding to other assets. On the other hand, the price of cryptocurrencies is completely regulated by the market.
Tokens can be:
• Utility tokens – something that accesses a user to a product or service and support dApps built on the blockchain.
• Governance tokens – fuel for voting systems executed on the blockchain.
• Transactional tokens – serve as a unit of accounts and used for trading.
• Security tokens – represent legal ownership of an asset, can be used in addition to or in place of a password.
Tokens are usually created through smart contracts and are often adapted to an ICO – initial coin offering, which is a means of crowdfunding. It is much easier to create tokens, that is why they make a majority of coins in existence. Altcoin and token blockchains work on the concept of smart contracts or decentralized applications, where the programmable, self-executing code is ruling the transactions within a blockchain. By the way, the vast majority of tokens were distributed on the Ethereum platform.

Forks

Generally a fork occurs when a protocol code, on which the blockchain is operating, is being changed, modified and updated by developers or users. Due to the changes, the blockchain splits into 2 paths: an old way of doing things and a new way. These changes may happen because: a disagreement between users and creators; a major hack, as it was with Ethereum; developers’ decision to fix errors and add new functionality. The blockchain mainly splits into hard forks and soft forks. Shortly speaking, coin hard forks cannot work with older versions while soft forks still can work with older versions.
Hard fork – after a hard fork, a new version is completely separated from the previous one, there’s no connection between them anymore, although the new version keeps the data of all the previous transactions but now on, each version will have its own transaction history. In order to use the new versions, every node has to upgrade their software. A hard fork requires majority support (or consensus) from coin holders with a connection to the coin network. If enough users don’t update then you will be unable to get a clean upgrade which could lead to a break in the blockchain.
Soft fork – a protocol change, but with backward compatibility. The rules of the network have been changed, but nodes running the old software will still be able to validate transactions, but those updated nodes won’t be able to mine new blocks. So to be used and useful, soft forks require the majority of the network’s hash power. Otherwise, they risk becoming set out and anyway ending up as a hard fork.

Stablecoins

As it comes from the name, stablecoins are price-stabilized that are becoming big in the crypto world. Still enjoying most of the “typical-cryptocurrency” benefits, it is standing out as a fixed and stable coin, not volatile at all. Stablecoins’ values are stabilized by pegging them to other assets such as the US Dollar or gold.
Stablecoins include Tether (USDT), Standard (PAX), Gemini Dollar (GUSD) which are backed by the US Dollar and approved by the New York State Department of Financial Services.

Conclusion

Now that we hacked into cryptocurrency, you probably understand that it is much less mysterious than it first seemed. Nowadays, cryptocurrencies are making the revolution of the financial institution. For example, Bitcoin is currently used in 96 countries and growing, with more than 12,000 transactions per hour. More and more investors are involved, banks and governments realize that these cutting edge technologies are prone to draw their control away. Cryptocurrencies are slowly changing the world and you can choose – either stand beside and observe or become part of history in the making.

The Mining Algorithm is as follows: Step 0 - Retrieve the hash of the previous block from the network. Step 1 - Gather a list of potential transactions known as a "block". This list of transactions comes from the peer-to-peer bitcoin network. Step 2 - Calculate a hash for a block of potential transactions along with a random number. Bitcoin is based on Proof of Work (PoW) algorithm, which is a computer language used to make complex calculations. Computers solving these calculations are awarded tokens as a result of their efforts, with the activity commonly known as mining. Miners get batches of BTC (abbreviation of bitcoin) through constant mining. When mining bitcoin, the hashcash algorithm repeatedly hashes the block header while incrementing the counter & extraNonce fields. Incrementing the extraNonce field entails recomputing the merkle tree, as the coinbase transaction is the left most leaf node. The block is also occasionally updated as you are working on it. Bitcoin mining is done by specialized computers. The role of miners is to secure the network and to process every Bitcoin transaction. Miners achieve this by solving a computational problem which allows them to chain together blocks of transactions (hence Bitcoin’s famous “blockchain”).. For this service, miners are rewarded with newly-created Bitcoins and transaction fees. Bitcoin mining is the process of creating new bitcoin by solving a computational puzzle.
