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!

The Unofficial Cardano FAQ - V3

(if you would like to add information or see mistakes, just comment below and I will credit you)
What is Cardano? Cardano is an open source and permissionless "Third Generation" blockchain project being developed by IOHK. Development and research started in 2015, with the 1.0 mainnet launching in 2017. Cardano blockchain is currently being developed into two layers. The first one is the ledger of account values, and the second one is the reason why values are transferred from one account to the other.
  1. Cardano Settlement Layer (CSL) - The CSL acts as the ledger of account or balance ledger. This is an idea created as an improvement of bitcoin blockchain. It uses a proof-of-stake consensus algorithm known as Ouroboros to generate new blocks and confirm transactions.
  2. Cardano Computation Layer (CCL) - The CCL contains the data how values are transferred. Since the computation layer is not connected to balance ledger, users of the CCL can create customized rules (smart contracts) when evaluating transactions. (https://support.bitkub.com/hc/en-us/articles/360006678892-What-are-the-two-layers-of-Cardano-)
IOHK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another development team - on the assumption that the voting infrastructure has been completed. However CEO Charles Hoskinson has stated that they will develop the project until it is completed, and they are simply financed until the end of 2020.
Cardano was the first project built on a peer-reviewed scientific development method, resulting in dozens of research papers produced by IOHK. Among these papers is Ouroboros Genesis, proving that a Proof of Stake protocol can be just as secure as Proof of Work - which was originally developed for Bitcoin, and refined for Ethereum. This PoS protocol considerably lowers the resources cost to maintain network while still maintaining security and network speed.
Cardano as a financial infrastructure is not yet completed, With significant development to be rolled out.
What were the other two generations of blockchain? Gen 1 was Bitcoin. It exists by itself and talks to nobody but Bitcoin. It is capable of peer to peer transactions without a third party in such a way that you cannot cheat the system. This was a major step forward for the E-cash concept that people have been working on for the 20 years prior.
Gen 2 was Ethereum and other smart-contract platforms that allow other coins and platforms to be built on top of their infrastructure. These coins can interact with others on the platform, but cannot interact with other platforms. Meaning it is still not truly interoperable. Most Gen 2 blockchains are also using Proof of Work likes Bitcoin, which effects scaling. Also missing is a built-in method to pay for upgrades and voting mechanics for decision making.
Gen 3 blockchains are a complete package designed to replace the current financial infrastructure of the world. Cardano is using Proof of Stake to ensure security and decentralisation(Shelley). Scaling through parallel computation (Hydra in Basho), Sidechains to allow the platform to interact with other platforms (Basho), and also include mechanisms for voting for project funding, changes to the protocol and improvement proposals (Voltaire). Finally smart contracts platform for new and established projects that are developer friendly (Goguen).
Who is the team behind Cardano? There are three organisations that are contributing to the development of Cardano. The first is the Cardano Foundation, an objective, non-profit organisation based in Switzerland. Its core responsibilities are to nurture, grow and educate Cardano users and commercial communities, to engage with authorities on regulatory and commercial matters and to act as a blockchain and cryptocurrency standards body. The second entity is IOHK, a leading cryptocurrency research and development company, which holds the contract to develop the platform until 2020. The final business partner is Emurgo, which invests in start-ups and assists commercial ventures to build on the Cardano blockchain.

What is the difference between Proof of Work and Proof of stake? Both these protocols are known as “consensus protocols” that confirm whether a transaction is valid or invalid without a middleman like Visa or your bank. Every node (active and updated copy of the blockchain) can agree that the transaction did take place legitimately. If more than half validators agree, then the ledger is updated and the transaction is now secured. Proof-of-Work (PoW) happens when a miner is elected to solve an exceptionally difficult math problem and gets credit for adding a verified block to the blockchain. Finding a solution is an arduous guessing game that takes a considerable amount of computing power to compete for the correct answer. It is like “pick a number between 1 and one trillion” and when you get it right, you get $30,000 in Bitcoin, so the more computers you have working on it, the faster you can solve it. Also the more people who are trying to solve the same block, the harder the algorithm, so it may become 1 in 20 trillion. The downside is the massive amounts of power required to run the computers that run the network, and the slow pace that blocks are solved. To “Hack” a PoW system, you need 51% of the computing power, which would allow you to deny transactions, or spend the same coin twice. At the moment there are 8 main mining operations for bitcoin, and 4 of them make up more that 51% of the mining power.
PoS instead selects a coin at random that already exists, and the person who owns that coin is elected to put the work in to validate the block. This means there is no contest and no guessing game. Some computer power is required, but only a fraction of a PoW system. The complex nature of selecting a coin that exists on the correct and longest chain and is owned by someone who can complete the block, AND in such a way that it is secure AND that computer currently running AND that person also having an incentive to complete the work, has made the development of PoS very slow. However only a few years ago it wasn’t even possible. In this method, the more of the coin (ADA) you stake, the more likely you are to be selected to close a block. Cardano also allows you to delegate your stake to someone else to validate the block so they do the work, and you share in the reward for doing so.
To “hack” a PoS blockchain you need to own 51% of the tokens, which is significantly harder than owning 51% of the computing power.
What is ADA and how is it different to Cardano? Cardano is the name of the network infrastructure, and can be thought of like a rail network. ADA is the native token that has been developed alongside Cardano to facilitate the network operation. This helps confusion and maintains distinction, compared to Ethereum being the native token of Ethereum. Similar to bitcoin or any other token, ADA can be sent peer to peer as payment, but is also the reward for running the network, and what is taken as transaction fees.
In this metaphor “Cardano” is the train tracks, that everything runs on. A stake pool would be the locomotive, facilitating transactions on the network while ADA is the coal that powers the locomotive. The train carriages are Decentralised applications (Dapps) that are also running on cardano tracks, but are not actively powering the network.
What is staking Cardano is a Proof of Stake protocol, and uses already existing coins like a marker to ensure security. The protocol chooses a coin at random and the owner of that coin is elected to validate a block of transactions. Staking is the process of adding your ADA coins to a Pool that has the resources to run the network. If the pool you have chosen to "delegate" your stake to is chosen to close/validate a block, then you get a portion of the rewards. The ADA never leaves your wallet, and you can "undelegate" whenever you like. this increases stability of the network and also gives an incentive to pool operators to invest the time and hardware required to run a pool.
What is a stake-pool and how does it work? Cardano.org FAQ on the issue goes into much more detail
A stake pool is where the computing power of the network takes place. During ITN there was 1200 registered stake pools while 300 were creating blocks. You can manage your own stake-pool or delegate your ADA to an already registered pool. Rewards are determined by the protocol, however the pool may elect to charge fee Percentages, or flat rate fee to upkeep their pool.
Can I Stake my ADA right now? The staking testnet has closed, If you participated in the Incentivised Test Net and earned rewards, instructions to check the balance are here.
However if you have just purchased some or it was held on an exchange, then you will need to wait until the Shelley mainnet launch happening at the end of July 2020.
Where do I stake my ADA? Daedalus Flight wallet, and Yoroi Wallet (as a chrome extension) are the current best options. Adalite and several other third-party wallets also exist. Coinbase will also allow staking as a custodial service, and many exchanges may offer “staking as a service” so you can leave your coins on the exchange and still earn rewards if you enjoy trading. I do not recommend leaving coins on an exchange unless you are actively trading.
What are the staking rewards now and what can I expect on a return in the future? The Incentivised Test Net (ITN) Delivered 10%-15%pa returns on average. The future of staking will most likely be lower, but will depend on the amount of ADA staked across the network and the amount of network traffic.
Check https://staking.cardano.org/en/calculato for a clearer picture.
what is a Pledge? To stop one person operating many pools, the rewards that a pool earns will vary depending on the amount of personal ADA they “pledge” to open the pool. This means that 50 pools with a 1,00ADA pledge each will be overall less profitable than 1-2 pool with the max ADA pledge (unknown but likely around 300k). Even if the 50 pools have the same over stake delegated by other users and have a better chance of being selected to close a block, the 50 pools may receive lower rewards.. (at least that is the theory)
Who is IOHK? IOHK is a for-profit software engineering company founded by CEO Charles Hoskinson and Jeremy Wood in 2015 that has taken a scientific approach to the development of blockchain. IOHK started with “first principles” and looked at questions like “what is a blockchain” and “what should a blockchain be able to do” rather than accepting the established paradigm of Bitcoin and Ethereum. IOHK was originally Input Output Hong Kong, but is now Input Output Global and is based in Wyoming USA employing over 230 staff. IOHK has established research labs in several universities in order to complete the Cardano project, and is also developing Ethereum Classic, Atala, Mantis and possibly other Blockchain related programs and infrastructure.
Who is Charles? Charles Hoskinson is an early adopter of cryptocurrencies, American entrepreneur and cryptocurrency specialist. Charles Co-founded Ethereum with Vitalik Buterin and 5-8 others, However he only worked on that project for approximately six-months. Charles is now the CEO of IOHK and the director of The Bitcoin Education Project.
Why isn’t ADA on coinbase? Cardano and coinbase have recently connected in a big way. With IOHK turning over all their ADA to the custodial services of Coinbase. This means that Cardano and Coinbase have been working together for some time and there is a strong partnership forming. Staking and cold storage will be available and trading on Coinbase will most likely become available after the release of Shelley (although no official word yet)
Why Doesn’t Cardano have a Wikipedia Page? Wikipedia has strict guidelines on what can be turned into an article. As there has been no coverage of Cardano from mainstream media or “noteworthy” sources, there is no article yet. Wikipedia will also not accept sources from IOHK as they are not considered “reliable” and must come from a third party. This will most likely change soon.
Cardano does have a dedicated community driven wiki
https://cardanowiki.info/wiki/Home
What is Atala and why do I care?*
Atala is a suite of services being developed on top of the cardano blockchain by IOHK that focusses on credential certification, for things like education, work history and degrees (Atala Prism). Product counterfeiting protection through registering products on a blockchain and create taper-proof provenance. This does not only apply to Gucci handbags, but also medication, art, and anything that can be counterfeited (Atala Scan). As well as supply chain tracking to see issues and inefficiencies with greater transparency(Atala Trace).
Im new, how much is a good investment?
Cardano is still a speculative market and although there is amazing potential here, it is still only potential. When investing in any High risk market like Crypto, only every invest what you are willing to lose. Cardano may be testing the 10c barrier now. But in March it dumped to 1.7c. And if you suddenly need your money back during the dump then you are out of luck. Do your research before you FOMO in. Start with a small amount and send it between wallets and exchanges to understand how the system works. Store your private keys offline (or online cloud service but encrypted) with a method that is unlikely to be damaged AND have multiple copies. So in the case of a house fire or a blow to the head, or the cloud service being shutdown/destroyed, you do not lose your money.

1. What is Energi

Energi is a self-funding (no ICO and no premine) cryptocurrency that has a purpose to become the world’s leading cryptocurrency with the unification of Smart Contracts, Governance and Self-funding Treasury to ensure longevity and enable rapid growth. You can read more about why we decided to self-fund and chose not to conduct an ICO here.
Energi provides a small allocation to Proof-of-Stake (PoS) rewards, takes a bulk of the coin issuance and gives it to its treasury and active Masternodes. Energi also allocates 10% on-going reward to the leadership of the Energi Backbone, which is significantly less compared to today’s ICOs’ rewarding their founders between 20–50% of the tokens distributed. Another trait that sets Energi apart from ICOs is they give an on-going 10% allocation through each block reward, rather than rewarding the founders up-front.

2. What are the Fundamentals of Energi?

  • Scalability
1 minute block times and a 2 megabyte block size limit provide Energi with a vast transaction capacity for regular on-chain transactions. This allows for plenty of space on the blockchain for extremely fast transactions with very low fees.
Energi features a powerful on-chain scaling solution with a system of incentivized full nodes called Energi Masternodes. A Masternode is a full node backed by 1,000 NRG collateral that provides level 2 scalability to the Energi Cryptocurrency. 40% of the emissions of Energi is allocated to Masternodes, providing an extremely strong incentive to grow the number of full nodes and scalability of the network.

  • Funding
A key feature of Energi is its powerful treasury system. Energi makes up to 40% of the emissions available to the treasury, to be utilized in a manner that provides maximum benefit.
Treasury allocation is decentralized, allowing for submitted proposals from anyone, to be voted on by Masternodes and paid out from the emissions.
Energi has a 14 day treasury cycle, allowing quick payments for proposal authors and contributors, as well as strategic responsiveness to effective proposals. Energi is guided by the principle that every dollar spent from its funding model should yield more than one dollar of value in return. Thanks to a 14 day treasury cycle, the Energi team is able to measure results and respond quickly to changes in strategy.

  • Governance
The Energi Treasury is a decentralized governance model designed with Masternodes as caretakers, with voting rights on how to best utilize treasury funding.
This governance model reduces risk by allowing participation from everyone who holds 1,000 NRG as a Masternode. In this way, the Energi community can work together on how to best build the strategic direction of Energi.

  • Inflation
Energi Cryptocurrency has a simple rate of inflation at 1 million coins per month with no maximum cap. This ensures consistency in funding allocation, Masternode rewards, and PoS rewards, making the economics of the cryptocurrency more understandable for everyone who chooses to participate in Energi.
No coin supply limit ensures that Energi is prepared for the long term, avoiding “bubble” economics caused by dramatic early inflation that in most coins only serves to benefit founders ahead of increased adoption.

  • Distribution
Energi conducted a fair launch on April 14, 2018 with no ICO and no premine. Prior to launch, the Energi team gave a specific time and date for the launch of its main net, which its vibrant community eagerly awaited, so that mining could begin fairly, again avoiding centralization among the coin founders (It's important to note that Energi has transitioned from Proof-of-Work consensus to a Proof-of-Stake consensus).
Energi Masternode payments were designed to begin at block 216000, which occurred on September 18, 2018, almost 160 days after launch. This ensured time to list Energi on exchanges, and to grow the community, encouraging fair and equitable distribution before the extremely powerful Masternode rewards began. It is all too common for Masternode coins to feature a premine, which has the effect of centralizing distribution among the founders and early adopters.
From 2018 to 2020, Energi distributed nearly 4 million coins to users who contributed to spreading awareness of the project with social media activities about Energi, such as tweets, follows, and subscriptions on all major social media platforms.

  • Decentralization
Decentralized governance with Masternodes helps to ensure everyone is able to participate in Energi and help guide the project to achieve the best results. The change to the requirement to run a Masternode, from 10 000 NRG to 1 000 NRG, has allowed more people to be involved and boosted decentralization for the whole project.

  • Long Term Vision
All of the above features seamlessly work together in concert, to ensure that Energi is prepared for the long term. Rather than try to closely find a niche in the market, Energi is prepared to adapt and overcome all challenges for many years to come. Energi’s use case is that of a traditional cryptocurrency, such as Bitcoin. However, Energi’s strategy is to excel by avoiding the pitfalls of previous projects, while further utilizing and improving upon the most powerful ideas in the cryptocurrency space.

3. Coin Specs

Ticker: NRG
Block time: 1 minute.
Hashing Algorithm: Dagger-Hashimoto (similar to Ethereum).
Masternode requirements: 1,000 Energi.
Treasury cycle: Every 14 days.
Approximately 1 million Energi will be released per month. The allocations can be observed easily as “10/10/40/40.”
10% will go to the Energi Backbone.
10% to the PoS participants
40% to Masternodes.
40% to the Treasury.
Thus, for every block, allocations are: 2.28 Energi to the Backbone, 2.28 Energi to the PoS participants, 9.14 Energi to the Treasury, and 9.14 Energi to Masternodes.
Since Treasury allocations are paid in two-week cycles, they are made in lump sums of approximately 184,000 Energi every 14 days.
In order to allow for widespread distribution of Energi before Masternode payments began, Masternode rewards were delayed until day 150. This was to allow the airdrop campaign to be completed and ensure a large amount of NRG is spread out through the community. Until that point, Masternode rewards were redirected to the Treasury. Thus for the first 5 months, the Treasury gained approximately 368,000 Energi every two weeks (about 800k Energi per month). The airdrop campaign was designed to release ~4 million Energi to the community.

Question: Is it possible currently or do you think it will in the future, to transact and send in fractions of a Satoshi? Can sidechains like lightning already accomplish this? Assuming hyperbitcoinization, it seems you would need a little bit more divisibility for small purchases eventually.

Cardano FAQ - V2

Cardano FAQ
What is Cardano? Cardano is an open source highly secure "Third Generation" blockchain project being developed by IOHK. Development and research started in 2015, with the 1.0 mainnet launching in 2017. Cardano blockchain is currently being developed into two layers. The first one is the ledger of account values, and the second one is the reason why values are transferred from one account to the other.
  1. Cardano Settlement Layer (CSL) - The CSL acts as the ledger of account or balance ledger. This is an idea created as an improvement of bitcoin blockchain. It uses a proof-of-stake consensus algorithm to generate new blocks and confirm transactions.
  2. Cardano Computation Layer (CCL) - The CCL contains the data how values are transferred. Since the computation layer is not connected to balance ledger, users of the CCL can create customized rules when evaluating transactions. (https://support.bitkub.com/hc/en-us/articles/360006678892-What-are-the-two-layers-of-Cardano-)
IOHK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another - on the assumption that the voting infrastructure has been completed. However CEO Charles Hoskinson has stated that they will develop the project until it is completed, and they are simply financed until the end of 2020.

What is the difference between PoS and PoW? Both these protocols are known as “consensus protocols” that confirm whether a transaction is valid or invalid without a middleman like Visa or your bank. Every node (active and updated copy of the blockchain) can agree that the transaction did take place legitimately. If more than half the network agrees, then the transaction is validated.

Can I Stake my ADA right now? If you had ADA in a Yoroi or Daedalus wallet before November 2019 then yes, you can stake. However if you have just purchased some or it was held on an exchange, then you will need to wait until August 18 (hopefully) for pools to start creating blocks, and first staking rewards will be 5 days later.
Where do I stake my ADA? Daedalus Flight wallet - Or Daedalus ITN, and Yoroi Wallet (as a chrome extension) are the current best options.
What are the staking rewards now and what can I expect on a return in the future? At the moment the Incentivised Test Net (ITN) is delivering 10%-15%pa returns on average. The future of staking will most likely be lower, but will depend on the amount of ADA staked across the network and the amount of network traffic. However it should not be completely dissimilar from the ITN, with most speculating 6%-10%pa compounding weekly….at this point there is no solid answer
what is a Pledge? To stop one person operating many pools, the rewards that a pool earns will vary depending on the amount of personal ADA they “pledge” to open the pool. This means that 100 pools with a 10,00ADA pledge will be overall less profitable than 1 pool with 1,000,000 ADA pledge. (at least that is the theory)

IOHK was originally Input Output Hong Kong, but is now Input Output Global and is based in Wyoming USA employing over 230 staff. IOHK has established research labs in several universities in order to complete the Cardano project, and is also developing Ethereum Classic, Atilia, Mantis and possibly other Blockchain related programs and infrastructure.
Who is Charles? Charles Hoskinson is an American entrepreneur and cryptocurrency specialist. Charles is often cited in the media as the Co-founder of Ethereum, but only worked on that project for approximately six-months. Charles is now the CEO of IOHK and the director of The Bitcoin Education Project.
Why isn’t ADA on coinbase? There is no official word specifically as to why Cardano is not on Coinbase, However there prevailing theory is that Coinbase requires the coins to be decentralised. and as Cardano is still being developed, it will not be added Shelley is released, or possibly never, it is totally up to coinbase. However Charles did mention in an AMA that IOG has been working with many exchanges for the Shelley rollout.
Why Doesn’t Cardano have a Wikipedia Page? Wikipedia has strict guidelines on what can be turned into an article. As there has been no coverage of Cardano from mainstream media or “noteworthy” sources, there is no article yet. Wikipedia will also not accept sources from IOHK as they are not considered “reliable” and must come from a third party. This will most likely change soon.
Cardano does have a dedicated community driven wiki

After partnering with some of the most innovative projects in crypto, we know a thing or two about cutting through noise and paying attention to exceptional projects. These projects usually impact the greater crypto community, similar to the Ethereum 2.0 piece we published a few weeks ago. Here’s why we think Polkadot will play a huge role in coming years and how Ankr is getting involved today.

What is Polkadot?

Polkadot is what we’re calling a “protocol disruptor” as it’s designed to enable seamless interoperability across blockchain networks. Polkadot is the flagship protocol and first project from the Swiss-based Web3 Foundation. Focused on R&D for promising decentralized protocols and applications, Polkadot is a fitting project that embodies Web3’s ethos.
This is achieved through multi-chain technology called “parachains.” Parachains are an application-specific data structure that is globally coherent and validatable by the validators of the Polkadot Relay Chain.
The network scales even further with parathreads that are scheduled on a dynamic basis. These threads allow parachains to share sharded slots, similar to smaller airplanes sharing a gate at an airport. In layman terms, Parathreads are essentially Polkadot’s own shards.

Why is Polkadot significant?

Polkadot have launched their mainnet recently and the DOT tokens can now be claimed. The launch and the first NPoS Validator elections have proven to be a catalyst for investor, community, and developer support. Just like Ethereum 2.0, Polkadot will be a PoS protocol. Critical differences from Ethereum 2.0 include on-chain governance, as well as proposals and chain upgrades to occur without requiring a hard fork.
We believe Polkadot andd Ethereum 2.0 to occupy over 50% of the total cryptocurrency market capitalization by the end of 2021, capturing a 135 billion USD market.

Ankr’s involvement in the Polkadot Ecosystem

Many blockchains have been launched with some form of PoS over the past years, whether it’s Vanilla or NPoS (Nominated Proof-of-Stake) in Polkadot’s case.
But the space currently lacks a de facto infrastructure for PoS protocols, like Bitmain has done for the Bitcoin network. Ankr looks to provide this for the PoS landscape. We are using our expertise in node deployment/management to provide the easiest way possible for everyone to access the multi-billion PoS market.
We seek to provide a decentralized and easy way to leverage Web3 solutions and the Polkadot ecosystem, including their Parachains. We hereby present four ways to get involved in Polkadot with Ankr.

  1. Put your DOTs to work by running a Validator! Optimize your earnings and secure the relay chain by staking DOT tokens, competing for nominations, participating in consensus with other validators and receiving block rewards for good performance. For optimized security, you can protect your Validator by hiding it behind a layer of Sentry nodes. We also provide a custom security package containing one or more Sentry nodes to protect your Validator. For inquiries on the security package, mail to [email protected]
  2. For data analytics companies and developers we provide easy access to transactions, usage data and insights on the Polkadot network with our one-click full node deployment.
    1. Ankr will contribute to the Polkadot ecosystem by deploying our own NPoS Validators, which will be available for receiving nominations later this week. Stay tuned for more information on how to easily delegate your DOTs to our Validators!
    2. We have joined the Web3 Bootcamp earlier this year and connected with many of the Polkadot Parachains developers. We have collaborated on bringing easy node deployment with the teams of Acala Network, Bifrost, ChainX, Darwinia and more to integrate their nodes on our platform. In addition, we already supported the Edgeware and the Kusama Network.

Polkadot Ecosystem projects supported by Ankr.
Both the Polkadot Validator and Full node are now available in our Node Market and we will publish the tutorials later today!

Some ETH Stacking Milestones

I just thought I’d list off some of the major milestones for ETH stacking just for a bit of fun. Feel free to reply with any more if you think I missed any major milestones.
For reference, I will be assuming that the supply of ETH will be under 125 million (125,000,000 ETH) for the foreseeable future. This is not a fixed cap, but realistically, the supply won’t be far from this number in the next few decades. This is based on this graph from ETHHub but considering a slightly later ETH 2.0 release. https://docs.ethhub.io/assets/images/issuance_graph.png
Current ETH supply: 111,071,000
0 ETH - What are you doing with your life? Buy some ETH and claim your part of the world computer, the global settlement layer or the emerging black hole of finance. Call it what you want, you can’t stop it's proliferation.
0.001 ETH - One Finney. One thousandth of an ETH is called a Finney. Named after Hal Finney
0.01633 ETH - The amount of ETH you would own if it were evenly distributed evenly between all 7.65 billion people on Earth (assuming a supply of 125 million ETH).
1 ETH - 1 whole ETH. Only around 125 million people could ever hope to own 1 ETH if it were equally distributed.
1.25 ETH - One 100 millionth of the ETH supply. (1/100,000,000)
2.7 ETH - You’re an Ethereanaire! If the total supply of Ether was evenly distributed between all of the world’s millionaires, they would each have 2.7 ETH. (Based on a 2019 Credit Suisse Report which estimated the number of millionaires worldwide at 46.8 million.)
3.14 ETH - Your slice of the Ethereum pi has an angle of 0.000009 degrees (125000000/3.14=40,000,000 360°/40,000,000=0.000009°).
3.2 ETH - 1/10th of a validator node. If ETH price goes up 1,000% or more, might 3.2ETH become the requirement for staking? (This is totally speculative and based on nothing.)
5.95 ETH - The 21 million club. This is Ethereum’s version of one Bitcoin. Only 21 million people could ever hope to own 1 Bitcoin and only 21 million people could own 5.95 ETH.
10 ETH - Double Digits! Only 12.5 million people could hope to have 10 ETH.
12.5 ETH - One 10 millionth of the total ETH supply. (1/10,000,000)
16 ETH - Half a validator node. Find a buddy or family member with another 16 ETH and you have yourselves a shared validator node!
32 ETH - Enough ETH to run an ETH 2.0 validator node!
42 ETH - The meaning of life. Blessed is your stack by the Ethereum gods.
43.5 ETH - 1 Bitcoin worth of ETH. Don’t worry, this one will get cheaper over time if you’re looking to buy 1 Bitcoin with your ETH. Not investment advice.
69 ETH - ayy lmao
100 ETH - ETH Centurion. Oowee that’s a lot of ETH! I’m sure holders of 100 ETH will be considered whales by the end of the next bullrun.
125 ETH - The one million club. (1/1,000,000) Only one million people could ever hope for 125 ETH. The Bitcoin equivalent of the 1 million club requires owning 21 Bitcoin.
320 ETH - You can run 10 32 ETH validator nodes.
324 ETH - EZPZ. For those of you who are out of the loop, a redditor by the name EZPZ was calling for $324 while we were falling down from $1,400 in 2018. Myself and I'm sure many other members or ETHTrader at the time thought that he was crazy. Oh how we were wrong
350 ETH - Tree fiddy.
420 ETH - 🎶 Smoke ETH everyday 🎶
750 ETH - Top 10,000 wallets. Congratulations, if you have 750 ETH or more in a single Ethereum wallet, you’re in the top 10,000 wallets!
1,250 ETH - One one hundred thousandth of the ETH supply. (1/100,000)
59,500 ETH - Congratulations! You’re an ETH billionaire. There are 2,100 billionaires on Earth. If the total supply of ETH were split between them evenly, each would get 59,500 ETH.
Reminder please do not share information about how many ETH you hold, especially if it is a significant amount. It is against the sub rules for your own security. Disclosing your ETH holdings makes you a target for hackers and criminals.

Polkadot Launch AMA Recap

Polkadot Launch AMA Recap

The Polkadot Telegram AMA below took place on June 10, 2020

https://preview.redd.it/4ti681okap951.png?width=4920&format=png&auto=webp&s=e21f6a9a276d35bb9cdec59f46744f23c37966ef
AMA featured:
Dieter Fishbein, Ecosystem Development Lead, Web3 Foundation
Logan Saether, Technical Education, Web3 Foundation
Will Pankiewicz, Master of Validators, Parity Technologies
Moderated by Dan Reecer, Community and Growth, Polkadot & Kusama at Web3 Foundation

Transcription compiled by Theresa Boettger, Polkadot Ambassador:

Dieter Fishbein, Ecosystem Development Lead, Web3 Foundation

Dan: Hey everyone, thanks for joining us for the Polkadot Launch AMA. We have Dieter Fishbein (Head of Ecosystem Development, our business development team), Logan Saether (Technical Education), and Will Pankiewicz (Master of Validators) joining us today.
We had some great questions submitted in advance, and we’ll start by answering those and learning a bit about each of our guests. After we go through the pre-submitted questions, then we’ll open up the chat to live Q&A and the hosts will answer as many questions as they can.
We’ll start off with Dieter and ask him a set of some business-related questions.

Dieter could you introduce yourself, your background, and your role within the Polkadot ecosystem?

Dieter: I got my start in the space as a cryptography researcher at the University of Waterloo. This is where I first learned about Bitcoin and started following the space. I spent the next four years or so on the investment team for a large asset manager where I primarily focused on emerging markets. In 2017 I decided to take the plunge and join the space full-time. I worked at a small blockchain-focused VC fund and then joined the Polkadot team just over a year ago. My role at Polkadot is mainly focused on ensuring there is a vibrant community of projects building on our technology.

Q: Adoption of Polkadot of the important factors that all projects need to focus on to become more attractive to the industry. So, what is Polkadot's plan to gain more Adoption? [sic]

A (Dieter): Polkadot is fundamentally a developer-focused product so much of our adoption strategy is focused around making Polkadot an attractive product for developers. This has many elements. Right now the path for most developers to build on Polkadot is by creating a blockchain using the Substrate framework which they will later connect to Polkadot when parachains are enabled. This means that much of our adoption strategy comes down to making Substrate an attractive tool and framework. However, it’s not just enough to make building on Substrate attractive, we must also provide an incentive to these developers to actually connect their Substrate-based chain to Polkadot. Part of this incentive is the security that the Polkadot relay chain provides but another key incentive is becoming interoperable with a rich ecosystem of other projects that connect to Polkadot. This means that a key part of our adoption strategy is outreach focused. We go out there and try to convince the best projects in the space that building on our technology will provide them with significant value-add. This is not a purely technical argument. We provide significant support to projects building in our ecosystem through grants, technical support, incubatoaccelerator programs and other structured support programs such as the Substrate Builders Program (https://www.substrate.io/builders-program). I do think we really stand out in the significant, continued support that we provide to builders in our ecosystem. You can also take a look at the over 100 Grants that we’ve given from the Web3 Foundation: https://medium.com/web3foundation/web3-foundation-grants-program-reaches-100-projects-milestone-8fd2a775fd6b

Q: On moving forward through your roadmap, what are your most important next priorities? Does the Polkadot team have enough fundamentals (Funds, Community, etc.) to achieve those milestones?

A (Dieter): I would say the top priority by far is to ensure a smooth roll-out of key Polkadot features such as parachains, XCMP and other key parts of the protocol. Our recent Proof of Authority network launch was only just the beginning, it’s crucial that we carefully and successfully deploy features that allow builders to build meaningful technology. Second to that, we want to promote adoption by making more teams aware of Polkadot and how they can leverage it to build their product. Part of this comes down to the outreach that I discussed before but a major part of it is much more community-driven and many members of the team focus on this.
We are also blessed to have an awesome community to make this process easier 🙂

Q: Where can a list of Polkadot's application-specific chains can be found?

A (Dieter): The best list right now is http://www.polkaproject.com/. This is a community-led effort and the team behind it has done a terrific job. We’re also working on providing our own resource for this and we’ll share that with the community when it’s ready.

Q: Could you explain the differences and similarities between Kusama and Polkadot?

A (Dieter): Kusama is fundamentally a less robust, faster-moving version of Polkadot with less economic backing by validators. It is less robust since we will be deploying new technology to Kusama before Polkadot so it may break more frequently. It has less economic backing than Polkadot, so a network takeover is easier on Kusama than on Polkadot, lending itself more to use cases without the need for bank-like security.
In exchange for lower security and robustness, we expect the cost of a parachain lease to be lower on Kusama than Polkadot. Polkadot will always be 100% focused on security and robustness and I expect that applications that deal with high-value transactions such as those in the DeFi space will always want a Polkadot deployment, I think there will be a market for applications that are willing to trade cheap, high throughput for lower security and robustness such as those in the gaming, content distribution or social networking sectors. Check out - https://polkadot.network/kusama-polkadot-comparing-the-cousins/ for more detailed info!

Q: and for what reasons would a developer choose one over the other?

A (Dieter): Firstly, I see some earlier stage teams who are still iterating on their technology choosing to deploy to Kusama exclusively because of its lower-stakes, faster moving environment where it will be easier for them to iterate on their technology and build their user base. These will likely encompass the above sectors I identified earlier. To these teams, Polkadot becomes an eventual upgrade path for them if, and when, they are able to perfect their product, build a larger community of users and start to need the increased stability and security that Polkadot will provide.
Secondly, I suspect many teams who have their main deployment on Polkadot will also have an additional deployment on Kusama to allow them to test new features, either their tech or changes to the network, before these are deployed to Polkadot mainnet.

Logan Saether, Technical Education, Web3 Foundation

Q: Sweet, let's move over to Logan. Logan - could you introduce yourself, your background, and your role within the Polkadot ecosystem?

A (Logan): My initial involvement in the industry was as a smart contract engineer. During this time I worked on a few projects, including a reboot of the Ethereum Alarm Clock project originally by Piper Merriam. However, I had some frustrations at the time with the limitations of the EVM environment and began to look at other tools which could help me build the projects that I envisioned. This led to me looking at Substrate and completing a bounty for Web3 Foundation, after which I applied and joined the Technical Education team. My responsibilities at the Technical Education team include maintaining the Polkadot Wiki as a source of truth on the Polkadot ecosystem, creating example applications, writing technical documentation, giving talks and workshops, as well as helping initiatives such as the Thousand Validator Programme.

Q: The first technical question submitted for you was: "When will an official Polkadot mobile wallet appear?"

A (Logan): There is already an “official” wallet from Parity Technologies called the Parity Signer. Parity Signer allows you to keep your private keys on an air-gapped mobile device and to interactively sign messages using web interfaces such as Polkadot JS Apps. If you’re looking for something that is more of an interface to the blockchain as well as a wallet, you might be interested in PolkaWallet which is a community team that is building a full mobile interface for Polkadot.
For more information on Parity Signer check out the website: https://www.parity.io/signe

Q: Great thanks...our next question is: If someone already developed an application to run on Ethereum, but wants the interoperability that Polkadot will offer, are there any advantages to rebuilding with Substrate to run as a parachain on the Polkadot network instead of just keeping it on Ethereum and using the Ethereum bridge for use with Polkadot?

A (Logan): Yes, the advantage you would get from building on Substrate is more control over how your application will interact with the greater Polkadot ecosystem, as well as a larger design canvas for future iterations of your application.
Using an Ethereum bridge will probably have more cross chain latency than using a Polkadot parachain directly. The reason for this is due to the nature of Ethereum’s separate consensus protocol from Polkadot. For parachains, messages can be sent to be included in the next block with guarantees that they will be delivered. On bridged chains, your application will need to go through more routes in order to execute on the desired destination. It must first route from your application on Ethereum to the Ethereum bridge parachain, and afterward dispatch the XCMP message from the Polkadot side of the parachain. In other words, an application on Ethereum would first need to cross the bridge then send a message, while an application as a parachain would only need to send the message without needing to route across an external bridge.

Q: DOT transfers won't go live until Web3 removes the Sudo module and token holders approve the proposal to unlock them. But when will staking rewards start to be distributed? Will it have to after token transfers unlock? Or will accounts be able to accumulate rewards (still locked) once the network transitions to NPoS?

A (Logan): Staking rewards will be distributed starting with the transition to NPoS. Transfers will still be locked during the beginning of this phase, but reward payments are technically different from the normal transfer mechanism. You can read more about the launch process and steps at http://polkadot.network/launch-roadmap

Q: Next question is: I'm interested in how Cumulus/parachain development is going. ETA for when we will see the first parachain registered working on Kusama or some other public testnet like Westend maybe?

A (Logan): Parachains and Cumulus is a current high priority development objective of the Parity team. There have already been PoC parachains running with Cumulus on local testnets for months. The current work now is making the availability and validity subprotocols production ready in the Polkadot client. The best way to stay up to date would be to follow the project boards on GitHub that have delineated all of the tasks that should be done. Ideally, we can start seeing parachains on Westend soon with the first real parachains being deployed on Kusama thereafter.
The projects board can be viewed here: https://github.com/paritytech/polkadot/projects
Dan: Also...check out Basti's tweet from yesterday on the Cumulus topic: https://twitter.com/bkchstatus/1270479898696695808?s=20

Q: In what ways does Polkadot support smart contracts?

A (Logan): The philosophy behind the Polkadot Relay Chain is to be as minimal as possible, but allow arbitrary logic at the edges in the parachains. For this reason, Polkadot does not support smart contracts natively on the Relay Chain. However, it will support smart contracts on parachains. There are already a couple major initiatives out there. One initiative is to allow EVM contracts to be deployed on parachains, this includes the Substrate EVM module, Parity’s Frontier, and projects such as Moonbeam. Another initiative is to create a completely new smart contract stack that is native to Substrate. This includes the Substrate Contracts pallet, and the ink! DSL for writing smart contracts.

Will Pankiewicz, Master of Validators, Parity Technologies


Q: (Dan) Thanks for all the answers. Now we’ll start going through some staking questions with Will related to validating and nominating on Polkadot. Will - could you introduce yourself, your background, and your role within the Polkadot ecosystem?

A (Will): Sure thing. Like many others, Bitcoin drew me in back in 2013, but it wasn't until Ethereum came that I took the deep dive into working in the space full time. It was the financial infrastructure aspects of cryptocurrencies I was initially interested in, and first worked on dexes, algorithmic trading, and crypto funds. I really liked the idea of "Generalized Mining" that CoinFund came up with, and started to explore the whacky ways the crypto funds and others can both support ecosystems and be self-sustaining at the same time. This drew me to a lot of interesting experiments in what later became DeFi, as well as running validators on Proof of Stake networks. My role in the Polkadot ecosystem as “Master of Validators” is ensuring the needs of our validator community get met.

Q: Cool thanks. Our first community question was "Is it still more profitable to nominate the validators with lesser stake?"

A (Will): It depends on their commission, but generally yes it is more profitable to nominate validators with lesser stake. When validators have lesser stake, when you nominate them this makes your nomination stake a higher percentage of total stake. This means when rewards get distributed, it will be split more favorably toward you, as rewards are split by total stake percentage. Our entire rewards scheme is that every era (6 hours in Kusama, 24 hours in Polkadot), a certain amount of rewards get distributed, where that amount of rewards is dependent on the total amount of tokens staked for the entire network (50% of all tokens staked is currently optimal). These rewards from the end of an era get distributed roughly equally to all validators active in the validator set. The reward given to each validator is then split between the validators and all their nominators, determined by the total stake that each entity contributes. So if you contribute to a higher percentage of the total stake, you will earn more rewards.

Q: What does priority ranking under nominator addresses mean? For example, what does it mean that nominator A has priority 1 and nominator B has priority 6?

A (Will): Priority ranking is just the index of the nomination that gets stored on chain. It has no effect on how stake gets distributed in Phragmen or how rewards get calculated. This is only the order that the nominator chose their validators. The way that stake from a nominator gets distributed from a nominator to validators is via Phragmen, which is an algorithm that will optimally put stake behind validators so that distribution is roughly equal to those that will get in the validator set. It will try to maximize the total amount at stake in the network and maximize the stake behind minimally staked validators.

Q: On Polkadot.js, what does it mean when there are nodes waiting on Polkadot?

**A (Will):**In Polkadot there is a fixed validator set size that is determined by governance. The way validators get in the active set is by having the highest amount of total stake relative to other validators. So if the validator set size is 100, the top 100 validators by total stake will be in the validator set. Those not active in the validator set will be considered “waiting”.

Q: Another question...Is it necessary to become a waiting validator node right now?

A (Will): It's not necessary, but highly encouraged if you actively want to validate on Polkadot. The longer you are in the waiting tab, the longer you get exposure to nominators that may nominate you.

Q: Will current validators for Kusama also validate for Polkadot? How strongly should I consider their history (with Kusama) when looking to nominate a good validator for DOTs?

A (Will): A lot of Kusama validators will also be validators for Polkadot, as KSM was initially distributed to DOT holders. The early Kusama Validators will also likely be the first Polkadot validators. Being a Kusama validator should be a strong indicator for who to nominate on Polkadot, as the chaos that has ensued with Kusama has allowed validators to battle test their infrastructure. Kusama validators by now are very familiar with tooling, block explorers, terminology, common errors, log formats, upgrades, backups, and other aspects of node operation. This gives them an edge against Polkadot validators that may be new to the ecosystem. You should strongly consider well known Kusama validators when making your choices as a nominator on Polkadot.

Q: Can you go into more details about the process for becoming a DOT validator? Is it similar as the KSM 1000 validators program?

A (Will): The Process for becoming a DOT validators is first to have DOTs. You cannot be a validator without DOTs, as DOTs are used to pay transaction fees, and the minimum amount of DOTs you need is enough to create a validate transaction. After obtaining enough DOTs, you will need to set up your validator infrastructure. Ideally you should have a validator node with specs that match what we call standard hardware, as well as one or more sentry nodes to help isolate the validator node from attacks. After the infrastructure is up and running, you should have your Polkadot accounts set up right with a stash bonded to a controller account, and then submit a validate transaction, which will tell the network your nodes are ready to be a part of the network. You should then try and build a community around your validator to let others know you are trustworthy so that they will nominate you. The 1000 validators programme for Kusama is a programme that gives a certain amount of nominations from the Web3 Foundation and Parity to help bootstrap a community and reputation for validators. There may eventually be a similar type of programme for Polkadot as well.
Dan: Thanks a lot for all the answers, Will. That’s the end of the pre-submitted questions and now we’ll open the chat up to live Q&A, and our three team members will get through as many of your questions as possible.
We will take questions related to business development, technology, validating, and staking. For those wondering about DOT:
DOT tokens do not exist yet. Allocations of Polkadot's native DOT token are technically and legally non-transferable. Hence any publicized sale of DOTs is unsanctioned by Web3 Foundation and possibly fraudulent. Any official public sale of DOTs will be announced on the Web3 Foundation website. Polkadot’s launch process started in May and full network decentralization later this year, holders of DOT allocations will determine issuance and transferability. For those who participated in previous DOT sales, you can learn how to claim your DOTs here (https://wiki.polkadot.network/docs/en/claims).


Telegram Community Follow-up Questions Addressed Below


Q: Polkadot looks good but it confuses me that there are so many other Blockchain projects. What should I pay attention in Polkadot to give it the importance it deserves? What are your planning to achieve with your project?

A (Will): Personally, what I think differentiates it is the governance process. Coordinating forkless upgrades and social coordination helps stand it apart.
A (Dieter): The wiki is awesome - https://wiki.polkadot.network/

Q: Over 10,000 ETH paid as a transaction fee , what if this happens on Polkadot? Is it possible we can go through governance to return it to the owner?

A: Anything is possible with governance including transaction reversals, if a network quorum is reached on a topic.
A (Logan): Polkadot transaction fees work differently than the fees on Ethereum so it's a bit more difficult to shoot yourself in the foot as the whale who sent this unfortunate transaction. See here for details on fees: https://w3f-research.readthedocs.io/en/latest/polkadot/Token%20Economics.html?highlight=transaction%20fees#relay-chain-transaction-fees-and-per-block-transaction-limits
However, there is a tip that the user can input themselves which they could accidentally set to a large amount. In this cases, yes, they could proposition governance to reduce the amount that was paid in the tip.

Q: What is the minimum ideal amount of DOT and KSM to have if you want to become a validator and how much technical knowledge do you need aside from following the docs?

A (Will): It depends on what the other validators in the ecosystem are staking as well as the validator set size. You just need to be in the top staking amount of the validator set size. So if its 100 validators, you need to be in the top 100 validators by stake.

Q: Will Web3 nominate validators? If yes, which criteria to be elected?

A (Will): Web 3 Foundation is running programs like the 1000 validators programme for Kusama. There's a possibility this will continue on for Polkadot as well after transfers are enabled. https://thousand-validators.kusama.network/#/
You will need to be an active validator to earn rewards. Only those active in the validator set earn rewards. I would recommend checking out parts of the wiki: https://wiki.polkadot.network/docs/en/maintain-guides-validator-payout

Q: Is it possible to implement hastables or dag with substrate?

A (Logan): Yes.

Q: Polkadot project looks very futuristic! But, could you tell us the main role of DOT Tokens in the Polkadot Ecosystem?

A (Dan): That's a good question. The short answer is Staking, Governance, Bonding. More here: http://polkadot.network/dot-token

Q: How did you manage to prove that the consensus protocol is safe and unbreakable mathematically?

A (Dieter): We have a research teams of over a dozen scientists with PhDs and post-docs in cryptography and distributed computing who do thorough theoretical analyses on all the protocols used in Polkadot

Q: What are the prospects for NFT?

A: Already being built 🙂

Q: What will be Polkadot next roadmap for 2020 ?

A (Dieter): Building. But seriously - we will continue to add many more features and upgrades to Polkadot as well as continue to strongly focus on adoption from other builders in the ecosystem 🙂

PSA, to get the full benefits of a hardware wallet, connect it to ur own full node. Only then is ur financial sovereignty complete.

"When you use the hardware wallet it is connecting to the ledgetrezor servers and telling you what you have in those addresses. You can’t actually verify what they are telling you is the truth. If you run your own node and connect that node to your wallets, you can verify the truth."
But that is not the only reason. The fact that only economic full nodes can help enforce concensus is perhaps just as important:
"Running a full node is kind of like voting where the weight of your vote is the amount of money you transact through that full node (sort of)."
In other words, when ur full node is not connected to ur actual BTC stash, u are giving up ur leverage to enforce consensus on the bitcoin network. Many don't realize that running a full node with an empty wallet does nothing for the network. It is completely redundant.
That happens a lot these days because bitcoin core's compatibility with hardware wallets is minimal. U need to run code to connect it, and even then it is cluncky, there isn't even a GUI. It also happens because folks don't know about the importance of economic nodes.
Here it is from the wiki:
As explained previously, full nodes enforce the consensus rules no matter what. However, lightweight nodes do not do this. Lightweight nodes do whatever the majority of mining power says. Therefore, if most of the miners got together to increase their block reward, for example, lightweight nodes would blindly go along with it. If this ever happened, the network would split such that lightweight nodes and full nodes would end up on separate networks, using separate currencies. People using lightweight nodes would be unable to transact with people using full nodes. If all businesses and many users are using full nodes, then this network split is not a critical problem because users of lightweight clients will quickly notice that they can't send or receive bitcoins to/from most of the people who they usually do business with, and so they'll stop using Bitcoin until the evil miners are overcome, which is the appropriate response. However, if almost everyone on the network is using lightweight nodes in this situation, then everyone would continue being able to transact with each other, and so Bitcoin could very well end up "hijacked" by evil miners.

Great video on Bitcoin protocol development & philosophy

This was a discussion between MIT Digital Currency Initiative's Neha Narula and Lightning Lab's Elizabeth Stark that happened a few days ago about Bitcoin development. I think as investors/traders it's important for us to stay up to date on what is happening in the development of the tech in order to make good trading/investing decisions.
Here are the most significant quotes, in my opinion (most from Neha):
3:12 - On protocol development
I think that there are four key areas to think about when you think about what's happening in Bitcoin core and what kinds of updates are being made. I've been listening along this morning its been a lot about bitcoin as an asset and digital currency as an asset class. Now we're going to talk about it as a technology, which id what it was originally and what it always will be and what the asset class depends on. I think the key thing to remember with Bitcoin is that they're always trying to improve four key areas: Better privacy, which makes it harder to censor transactions. Better performance which makes it easier to run a full node and therefore makes the network more decentralized. Better robustness, making it harder to attack in general. And then, functionality.
4:32 - On development philosophy
Another big part of the philosophy I think and something that's driving a lot of the new functionality changes is we really need to minimize what goes on chain. So this is in pretty stark contrast to a lot of smart contract platforms which execute every step of every smart contract on chain. It's like you take the program you want to run, you put the whole thing on the chain. Bitcoin's going for a slightly different approach, that approach is let's do as little on chain as possible. [Stark asks where this originated from, if Satoshi had some of these ideas] Yea, I think whoever designed Bitcoin script was definitely thinking a lot about this. It comes from the fact that, A blockchain is replicated across thousands of nodes, and hopefully one day millions if not billions of nodes, you can't execute everything that way you gotta be really careful you gotta think about what goes on chain. I think that's part of the ethos, and that's where we see things like Taproot/Schnorr.
5:37 - On what Taproot/Schnorr is
6:43 - On the speed of Bitcoin development
Bitcoin development is a little slow, but the reason is because there's nobody in charge..and people care a lot about robustness and they really care about doing good code review and making sure that this stuff is solid before it gets in.
7:30 - More on the philosophy of development
The base chain needs to be as simple as possible and needs to have the hooks necessary to support higher level functionality, that's the idea. [Stark comments on not having the complexity in the middle of the network]. We're building bitcoin to be around for centuries. The idea here is you put as little as possible into that base layer. You don't want to involve the base layer, you don't want to be constantly be re-writing the base layer. You want to have a base layer that is really, really robust. Something we've seen a lot is complexity is really the enemy of security. If you have a very complicated protocol, if you have really complicated functionality, guess what? That's a huge attack surface. The whole point of this technology is to be secure. We're removing the trusted third party, we're relying on cryptography and software and so that really needs to be secure, and sometimes I just think people do not take that seriously enough.
10:07 - More on the philosophy of development
We are building software that is supposed to run for a very long time. If there's anything that I can tell people about today, it's to tell them about this philosophy, this mindset of trying to build software that is super robust. And that's sort of the interesting thing that have been happening in Bitcoin development too, like one big change is removing code. They removed openSSL which is a library for a lot of cryptographic function and this was super celebrated because a third party library is a source of bugs, a source of consensus failure, people have different versions on their machine. So removing this was a huge win, actually. Makes the network more secure.
11:07 - On mainstream adoption and what that means
13:20 - On funding open-source development
15:21 - On the Lightning Network (goes until end)
Side note: In my opinion, this is one of the reasons why Bitcoin has and will continue to succeed: there are word-class developers and scientists improving the protocol. I mean, just look at these people's fucking pedigrees:
Stark previously taught at Stanford and Yale University about the future of the internet, and was a visiting fellow at Yale’s Information Society Project...She has advised startups ranging from decentralized technology to AI and was an entrepreneur-in-residence at Stanford StartX. Stark holds a J.D. from Harvard.

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!

Simplified Payment Verification (SPV) – using Bitcoin without running a full network node. By default, upon receiving a new transaction a node must validate it: in particular, verify that none of the transaction's inputs have been previously spent. To carry out that check the node needs to access the blockchain. Bitcoin Cash brings sound money to the world. Merchants and users are empowered with low fees and reliable confirmations. The future shines brightly with unrestricted growth, global adoption, permissionless innovation, and decentralized development. The Bitcoin Wiki Launched! New Bitcoin Wiki aim to provide a correct and up-to date set of information on the Bitcoin network and its features and functionality. View the Bitcoin Wiki. This website is intended for a technical audience. It presents information about the Bitcoin SV Node software implementation run by miners and other participants Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network. Special Cases. Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run Therefore this would be an appropriate term to describe a publicly connectable Full Bitcoin Node. This means many nodes can connect to it to obtain relayed transactional data and blockchain history. This may require more bandwidth and CPU than a Full Node because of all the extra work it’s doing.
