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!

How to Withdraw Your LBC LBRY Credits Coins From lbry.tv?

The coins you earned on lbry.tv which are actually LBC lbry credits which is a coin and native currency value of lbry platform and blockchain to transfer value and for other use cases. The lbry.tv platform offer you complete freedom of choice and doesn’t hold your funds in their wallet or servers the coins credits you can transfer directly and instantly to the wallet and you can transfer it immediately to any address of supportive LBC exchange or any other LBC blockchain wallet address.
So, therefore, there is no option of withdrawing because there is no minimum or selective day of withdrawing requirement compare to other centralized platforms. So furthermore now we need to consider how we can spend these earned coins because we cannot directly pay them to anyone and can exchange it with services and goods of value that’s why we need to exchange LBC to USD or your own region native fiat currency.

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.

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!

Introducing the IBIS Brokers affiliate program

Attn: Mods, I couldn't find anything against this type of post in the rules, but feel free to ping me and I'll amend/take down this post as per your feedback.
Hi Guys;
As brief intro, my name is Bruce, and I'm a team member at IBIS Brokers (IBISBrokers.com), which is a spin-off from ICO Launch Malta (ICOMalta.com) one of the larger Blockchain development companies in Europe. IBIS is at its core a large block OTC trading desk, however, we are days away from launching a retail product built with affiliates such as yourselves in mind.
In a nutshell we've developed a simple embeddable widget which would allow any site owner to sell cryptocurrency to users on their site via credit/debit card. All the KYC/AML, licensing, fraud checks, chargebacks etc are handled and shouldered by us, affiliates simply decide what margin they would like to add on to the user fees (Between 0-5%) and will receive their commissions in BTC at the end of every month. The beauty of this solution is that it offers real value to your audience (the convenience of purchasing crypto with credit card, rather than bank wires) whilst letting you keep the user on your site.
There are more details here: https://ibisbrokers.com/become-a-bitcoin-broke and I look forward to answering any questions you may have about the program/product.

Beginner’s Guide to BitMEX

Beginner’s Guide to BitMEX

https://preview.redd.it/fl5e0q7i3cc41.jpg?width=1024&format=pjpg&auto=webp&s=445485d722839a9adc1ae13db4c965b0ae3e67b7
Founded by HDR Global Trading Limited (which in turn was founded by former bankers Arthur Hayes, Samuel Reed and Ben Delo) in 2014, BitMEX is a trading platform operating around the world and registered in the Seychelles.
Meaning Bitcoin Mercantile Exchange, BitMEX is one of the largest Bitcoin trading platforms currently operating, with a daily trading volume of over 35,000 BTC and over 540,000 accesses monthly and a trading history of over $34 billion worth of Bitcoin since its inception.

https://preview.redd.it/coenpm4k3cc41.jpg?width=808&format=pjpg&auto=webp&s=8832dcafa5bd615b511bbeb6118ef43d73ed785e
Unlike many other trading exchanges, BitMEX only accepts deposits through Bitcoin, which can then be used to purchase a variety of other cryptocurrencies. BitMEX specialises in sophisticated financial operations such as margin trading, which is trading with leverage. Like many of the exchanges that operate through cryptocurrencies, BitMEX is currently unregulated in any jurisdiction.
Visit BitMEX

How to Sign Up to BitMEX

In order to create an account on BitMEX, users first have to register with the website. Registration only requires an email address, the email address must be a genuine address as users will receive an email to confirm registration in order to verify the account. Once users are registered, there are no trading limits. Traders must be at least 18 years of age to sign up.
https://preview.redd.it/0v13qoil3cc41.jpg?width=808&format=pjpg&auto=webp&s=e6134bc089c4e352dce10d754dc84ff11a4c7994
However, it should be noted that BitMEX does not accept any US-based traders and will use IP checks to verify that users are not in the US. While some US users have bypassed this with the use of a VPN, it is not recommended that US individuals sign up to the BitMEX service, especially given the fact that alternative exchanges are available to service US customers that function within the US legal framework.
How to Use BitMEX
BitMEX allows users to trade cryptocurrencies against a number of fiat currencies, namely the US Dollar, the Japanese Yen and the Chinese Yuan. BitMEX allows users to trade a number of different cryptocurrencies, namely Bitcoin, Bitcoin Cash, Dash, Ethereum, Ethereum Classic, Litecoin, Monero, Ripple, Tezos and Zcash.
The trading platform on BitMEX is very intuitive and easy to use for those familiar with similar markets. However, it is not for the beginner. The interface does look a little dated when compared to newer exchanges like Binance and Kucoin’s.
Once users have signed up to the platform, they should click on Trade, and all the trading instruments will be displayed beneath.
Clicking on the particular instrument opens the orderbook, recent trades, and the order slip on the left. The order book shows three columns – the bid value for the underlying asset, the quantity of the order, and the total USD value of all orders, both short and long.
The widgets on the trading platform can be changed according to the user’s viewing preferences, allowing users to have full control on what is displayed. It also has a built in feature that provides for TradingView charting. This offers a wide range of charting tool and is considered to be an improvement on many of the offering available from many of its competitors.
https://preview.redd.it/fabg1nxo3cc41.jpg?width=808&format=pjpg&auto=webp&s=6d939889c3eac15ab1e78ec37a8ccd13fc5e0573
Once trades are made, all orders can be easily viewed in the trading platform interface. There are tabs where users can select their Active Orders, see the Stops that are in place, check the Orders Filled (total or partially) and the trade history. On the Active Orders and Stops tabs, traders can cancel any order, by clicking the “Cancel” button. Users also see all currently open positions, with an analysis if it is in the black or red.
BitMEX uses a method called auto-deleveraging which BitMEX uses to ensure that liquidated positions are able to be closed even in a volatile market. Auto-deleveraging means that if a position bankrupts without available liquidity, the positive side of the position deleverages, in order of profitability and leverage, the highest leveraged position first in queue. Traders are always shown where they sit in the auto-deleveraging queue, if such is needed.
Although the BitMEX platform is optimized for mobile, it only has an Android app (which is not official). There is no iOS app available at present. However, it is recommended that users use it on the desktop if possible.
BitMEX offers a variety of order types for users:
  • Limit Order (the order is fulfilled if the given price is achieved);
  • Market Order (the order is executed at current market price);
  • Stop Limit Order (like a stop order, but allows users to set the price of the Order once the Stop Price is triggered);
  • Stop Market Order (this is a stop order that does not enter the order book, remain unseen until the market reaches the trigger);
  • Trailing Stop Order (it is similar to a Stop Market order, but here users set a trailing value that is used to place the market order);
  • Take Profit Limit Order (this can be used, similarly to a Stop Order, to set a target price on a position. In this case, it is in respect of making gains, rather than cutting losses);
  • Take Profit Market Order (same as the previous type, but in this case, the order triggered will be a market order, and not a limit one)
The exchange offers margin trading in all of the cryptocurrencies displayed on the website. It also offers to trade with futures and derivatives – swaps.

Futures and Swaps

A futures contract is an agreement to buy or sell a given asset in the future at a predetermined price. On BitMEX, users can leverage up to 100x on certain contracts.
Perpetual swaps are similar to futures, except that there is no expiry date for them and no settlement. Additionally, they trade close to the underlying reference Index Price, unlike futures, which may diverge substantially from the Index Price.
BitMEX also offers Binary series contracts, which are prediction-based contracts which can only settle at either 0 or 100. In essence, the Binary series contracts are a more complicated way of making a bet on a given event.
The only Binary series betting instrument currently available is related to the next 1mb block on the Bitcoin blockchain. Binary series contracts are traded with no leverage, a 0% maker fee, a 0.25% taker fee and 0.25% settlement fee.

Bitmex Leverage

BitMEX allows its traders to leverage their position on the platform. Leverage is the ability to place orders that are bigger than the users’ existing balance. This could lead to a higher profit in comparison when placing an order with only the wallet balance. Trading in such conditions is called “Margin Trading.”
There are two types of Margin Trading: Isolated and Cross-Margin. The former allows the user to select the amount of money in their wallet that should be used to hold their position after an order is placed. However, the latter provides that all of the money in the users’ wallet can be used to hold their position, and therefore should be treated with extreme caution.
https://preview.redd.it/eg4qk9qr3cc41.jpg?width=808&format=pjpg&auto=webp&s=c3ca8cdf654330ce53e8138d774e72155acf0e7e
The BitMEX platform allows users to set their leverage level by using the leverage slider. A maximum leverage of 1:100 is available (on Bitcoin and Bitcoin Cash). This is quite a high level of leverage for cryptocurrencies, with the average offered by other exchanges rarely exceeding 1:20.

BitMEX Fees

For traditional futures trading, BitMEX has a straightforward fee schedule. As noted, in terms of leverage offered, BitMEX offers up to 100% leverage, with the amount off leverage varying from product to product.
However, it should be noted that trading at the highest leverages is sophisticated and is intended for professional investors that are familiar with speculative trading. The fees and leverage are as follows:
https://preview.redd.it/wvhiepht3cc41.jpg?width=730&format=pjpg&auto=webp&s=0617eb894c13d3870211a01d51af98561907cb99

https://preview.redd.it/qhi8izcu3cc41.jpg?width=730&format=pjpg&auto=webp&s=09da4efe1de4214b0b5b9c7501aba5320e846b4c
However, there are additional fees for hidden / iceberg orders. A hidden order pays the taker fee until the entire hidden quantity is completely executed. Then, the order will become normal, and the user will receive the maker rebate for the non-hidden amount.

Deposits and Withdrawals

BitMEX does not charge fees on deposits or withdrawals. However, when withdrawing Bitcoin, the minimum Network fee is based on blockchain load. The only costs therefore are those of the banks or the cryptocurrency networks.
As noted previously, BitMEX only accepts deposits in Bitcoin and therefore Bitcoin serves as collateral on trading contracts, regardless of whether or not the trade involves Bitcoin.
The minimum deposit is 0.001 BTC. There are no limits on withdrawals, but withdrawals can also be in Bitcoin only. To make a withdrawal, all that users need to do is insert the amount to withdraw and the wallet address to complete the transfer.
https://preview.redd.it/xj1kbuew3cc41.jpg?width=808&format=pjpg&auto=webp&s=68056f2247001c63e89c880cfbb75b2f3616e8fe
Deposits can be made 24/7 but withdrawals are processed by hand at a recurring time once per day. The hand processed withdrawals are intended to increase the security levels of users’ funds by providing extra time (and email notice) to cancel any fraudulent withdrawal requests, as well as bypassing the use of automated systems & hot wallets which may be more prone to compromise.

Supported Currencies

BitMEX operates as a crypto to crypto exchange and makes use of a Bitcoin-in/Bitcoin-out structure. Therefore, platform users are currently unable to use fiat currencies for any payments or transfers, however, a plus side of this is that there are no limits for trading and the exchange incorporates trading pairs linked to the US Dollar (XBT), Japanese Yen (XBJ), and Chinese Yuan (XBC).
BitMEX supports the following cryptocurrencies:
  • Bitcoin (XBT)
  • Bitcoin Cash (BCH)
  • Ethereum (ETH)
  • Ethereum Classic (ETC)
  • Litecoin (LTC)
  • Ripple Token (XRP)
  • Monero (XMR)
  • Dash (DASH)
  • Zcash (ZEC)
  • Cardano (ADA)
  • Tron (TRX)
  • EOS Token (EOS)
BitMEX also offers leverage options on the following coins:
  • 5x: Zcash (ZEC)
  • 20x : Ripple (XRP),Bitcoin Cash (BCH), Cardano (ADA), EOS Token (EOS), Tron (TRX)
  • 25x: Monero (XMR)
  • 33x: Litecoin (LTC)
  • 50x: Ethereum (ETH)
  • 100x: Bitcoin (XBT), Bitcoin / Yen (XBJ), Bitcoin / Yuan (XBC)

Trading Technologies International Partnership

HDR Global Trading, the company which owns BitMEX, has recently announced a partnership with Trading Technologies International, Inc. (TT), a leading international high-performance trading software provider.
The TT platform is designed specifically for professional traders, brokers, and market-access providers, and incorporates a wide variety of trading tools and analytical indicators that allow even the most advanced traders to customize the software to suit their unique trading styles. The TT platform also provides traders with global market access and trade execution through its privately managed infrastructure and the partnership will see BitMEX users gaining access to the trading tools on all BitMEX products, including the popular XBT/USD Perpetual Swap pairing.
https://preview.redd.it/qcqunaby3cc41.png?width=672&format=png&auto=webp&s=b77b45ac2b44a9af30a4985e3d9dbafc9bbdb77c

The BitMEX Insurance Fund

The ability to trade on leverage is one of the exchange’s main selling points and offering leverage and providing the opportunity for traders to trade against each other may result in a situation where the winners do not receive all of their expected profits. As a result of the amounts of leverage involved, it’s possible that the losers may not have enough margin in their positions to pay the winners.
Traditional exchanges like the Chicago Mercantile Exchange (CME) offset this problem by utilizing multiple layers of protection and cryptocurrency trading platforms offering leverage cannot currently match the levels of protection provided to winning traders.
In addition, cryptocurrency exchanges offering leveraged trades propose a capped downside and unlimited upside on a highly volatile asset with the caveat being that on occasion, there may not be enough funds in the system to pay out the winners.
To help solve this problem, BitMEX has developed an insurance fund system, and when a trader has an open leveraged position, their position is forcefully closed or liquidated when their maintenance margin is too low.
Here, a trader’s profit and loss does not reflect the actual price their position was closed on the market, and with BitMEX when a trader is liquidated, their equity associated with the position drops down to zero.
In the following example, the trader has taken a 100x long position. In the event that the mark price of Bitcoin falls to $3,980 (by 0.5%), then the position gets liquidated with the 100 Bitcoin position needing to be sold on the market.
This means that it does not matter what price this trade executes at, namely if it’s $3,995 or $3,000, as from the view of the liquidated trader, regardless of the price, they lose all the equity they had in their position, and lose the entire one Bitcoin.
https://preview.redd.it/wel3rka04cc41.png?width=669&format=png&auto=webp&s=3f93dac2d3b40aa842d281384113d2e26f25947e
Assuming there is a fully liquid market, the bid/ask spread should be tighter than the maintenance margin. Here, liquidations manifest as contributions to the insurance fund (e.g. if the maintenance margin is 50bps, but the market is 1bp wide), and the insurance fund should rise by close to the same amount as the maintenance margin when a position is liquidated. In this scenario, as long as healthy liquid markets persist, the insurance fund should continue its steady growth.
The following graphs further illustrate the example, and in the first chart, market conditions are healthy with a narrow bid/ask spread (just $2) at the time of liquidation. Here, the closing trade occurs at a higher price than the bankruptcy price (the price where the margin balance is zero) and the insurance fund benefits.
Illustrative example of an insurance contribution – Long 100x with 1 BTC collateral
https://preview.redd.it/is89ep924cc41.png?width=699&format=png&auto=webp&s=f0419c68fe88703e594c121b5b742c963c7e2229
(Note: The above illustration is based on opening a 100x long position at $4,000 per BTC and 1 Bitcoin of collateral. The illustration is an oversimplification and ignores factors such as fees and other adjustments.
The bid and offer prices represent the state of the order book at the time of liquidation. The closing trade price is $3,978, representing $1 of slippage compared to the $3,979 bid price at the time of liquidation.)
The second chart shows a wide bid/ask spread at the time of liquidation, here, the closing trade takes place at a lower price than the bankruptcy price, and the insurance fund is used to make sure that winning traders receive their expected profits.
This works to stabilize the potential for returns as there is no guarantee that healthy market conditions can continue, especially during periods of heightened price volatility. During these periods, it’s actually possible that the insurance fund can be used up than it is built up.
Illustrative example of an insurance depletion – Long 100x with 1 BTC collateral
https://preview.redd.it/vb4mj3n54cc41.png?width=707&format=png&auto=webp&s=0c63b7c99ae1c114d8e3b947fb490e9144dfe61b
(Notes: The above illustration is based on opening a 100x long position at $4,000 per BTC and 1 Bitcoin of collateral. The illustration is an oversimplification and ignores factors such as fees and other adjustments.
The bid and offer prices represent the state of the order book at the time of liquidation. The closing trade price is $3,800, representing $20 of slippage compared to the $3,820 bid price at the time of liquidation.)
The exchange declared in February 2019, that the BitMEX insurance fund retained close to 21,000 Bitcoin (around $70 million based on Bitcoin spot prices at the time).
This figure represents just 0.007% of BitMEX’s notional annual trading volume, which has been quoted as being approximately $1 trillion. This is higher than the insurance funds as a proportion of trading volume of the CME, and therefore, winning traders on BitMEX are exposed to much larger risks than CME traders as:
  • BitMEX does not have clearing members with large balance sheets and traders are directly exposed to each other.
  • BitMEX does not demand payments from traders with negative account balances.
  • The underlying instruments on BitMEX are more volatile than the more traditional instruments available on CME.
Therefore, with the insurance fund remaining capitalized, the system effectively with participants who get liquidated paying for liquidations, or a losers pay for losers mechanism.
This system may appear controversial as first, though some may argue that there is a degree of uniformity to it. It’s also worth noting that the exchange also makes use of Auto Deleveraging which means that on occasion, leveraged positions in profit can still be reduced during certain time periods if a liquidated order cannot be executed in the market.
More adventurous traders should note that while the insurance fund holds 21,000 Bitcoin, worth approximately 0.1% of the total Bitcoin supply, BitMEX still doesn’t offer the same level of guarantees to winning traders that are provided by more traditional leveraged trading platforms.
Given the inherent volatility of the cryptocurrency market, there remains some possibility that the fund gets drained down to zero despite its current size. This may result in more successful traders lacking confidence in the platform and choosing to limit their exposure in the event of BitMEX being unable to compensate winning traders.

How suitable is BitMEX for Beginners?

BitMEX generates high Bitcoin trading levels, and also attracts good levels of volume across other crypto-to-crypto transfers. This helps to maintain a buzz around the exchange, and BitMEX also employs relatively low trading fees, and is available round the world (except to US inhabitants).
This helps to attract the attention of people new to the process of trading on leverage and when getting started on the platform there are 5 main navigation Tabs to get used to:
  • **Trade:**The trading dashboard of BitMEX. This tab allows you to select your preferred trading instrument, and choose leverage, as well as place and cancel orders. You can also see your position information and view key information in the contract details.
  • **Account:**Here, all your account information is displayed including available Bitcoin margin balances, deposits and withdrawals, and trade history.
  • **Contracts:**This tab covers further instrument information including funding history, contract sizes; leverage offered expiry, underlying reference Price Index data, and other key features.
  • **References:**This resource centre allows you to learn about futures, perpetual contracts, position marking, and liquidation.
  • **API:**From here you can set up an API connection with BitMEX, and utilize the REST API and WebSocket API.
BitMEX also employs 24/7 customer support and the team can also be contacted on their Twitter and Reddit accounts.
In addition, BitMEX provides a variety of educational resources including an FAQ section, Futures guides, Perpetual Contracts guides, and further resources in the “References” account tab.
For users looking for more in depth analysis, the BitMEX blog produces high level descriptions of a number of subjects and has garnered a good reputation among the cryptocurrency community.
Most importantly, the exchange also maintains a testnet platform, built on top of testnet Bitcoin, which allows anyone to try out programs and strategies before moving on to the live exchange.
This is crucial as despite the wealth of resources available, BitMEX is not really suitable for beginners, and margin trading, futures contracts and swaps are best left to experienced, professional or institutional traders.
Margin trading and choosing to engage in leveraged activity are risky processes and even more advanced traders can describe the process as a high risk and high reward “game”. New entrants to the sector should spend a considerable amount of time learning about margin trading and testing out strategies before considering whether to open a live account.

Is BitMEX Safe?

BitMEX is widely considered to have strong levels of security. The platform uses multi-signature deposits and withdrawal schemes which can only be used by BitMEX partners. BitMEX also utilises Amazon Web Services to protect the servers with text messages and two-factor authentication, as well as hardware tokens.
BitMEX also has a system for risk checks, which requires that the sum of all account holdings on the website must be zero. If it’s not, all trading is immediately halted. As noted previously, withdrawals are all individually hand-checked by employees, and private keys are never stored in the cloud. Deposit addresses are externally verified to make sure that they contain matching keys. If they do not, there is an immediate system shutdown.

In addition, the BitMEX trading platform is written in kdb+, a database and toolset popular amongst major banks in high frequency trading applications. The BitMEX engine appears to be faster and more reliable than some of its competitors, such as Poloniex and Bittrex.
They have email notifications, and PGP encryption is used for all communication.
The exchange hasn’t been hacked in the past.

How Secure is the platform?

As previously mentioned, BitMEX is considered to be a safe exchange and incorporates a number of security protocols that are becoming standard among the sector’s leading exchanges. In addition to making use of Amazon Web Services’ cloud security, all the exchange’s systems can only be accessed after passing through multiple forms of authentication, and individual systems are only able to communicate with each other across approved and monitored channels.
Communication is also further secured as the exchange provides optional PGP encryption for all automated emails, and users can insert their PGP public key into the form inside their accounts.
Once set up, BitMEX will encrypt and sign all the automated emails sent by you or to your account by the [[email protected]](mailto:[email protected]) email address. Users can also initiate secure conversations with the support team by using the email address and public key on the Technical Contact, and the team have made their automated system’s PGP key available for verification in their Security Section.
The platform’s trading engine is written in kdb+, a database and toolset used by leading financial institutions in high-frequency trading applications, and the speed and reliability of the engine is also used to perform a full risk check after every order placement, trade, settlement, deposit, and withdrawal.
All accounts in the system must consistently sum to zero, and if this does not happen then trading on the platform is immediately halted for all users.
With regards to wallet security, BitMEX makes use of a multisignature deposit and withdrawal scheme, and all exchange addresses are multisignature by default with all storage being kept offline. Private keys are not stored on any cloud servers and deep cold storage is used for the majority of funds.
Furthermore, all deposit addresses sent by the BitMEX system are verified by an external service that works to ensure that they contain the keys controlled by the founders, and in the event that the public keys differ, the system is immediately shut down and trading halted. The exchange’s security practices also see that every withdrawal is audited by hand by a minimum of two employees before being sent out.

BitMEX Customer Support

The trading platform has a 24/7 support on multiple channels, including email, ticket systems and social media. The typical response time from the customer support team is about one hour, and feedback on the customer support generally suggest that the customer service responses are helpful and are not restricted to automated responses.

The BitMEX also offers a knowledge base and FAQs which, although they are not necessarily always helpful, may assist and direct users towards the necessary channels to obtain assistance.
BitMEX also offers trading guides which can be accessed here

Conclusion

There would appear to be few complaints online about BitMEX, with most issues relating to technical matters or about the complexities of using the website. Older complaints also appeared to include issues relating to low liquidity, but this no longer appears to be an issue.
BitMEX is clearly not a platform that is not intended for the amateur investor. The interface is complex and therefore it can be very difficult for users to get used to the platform and to even navigate the website.
However, the platform does provide a wide range of tools and once users have experience of the platform they will appreciate the wide range of information that the platform provides.

My Ethereum Prediction From 2017. Still Think I was Wrong?

Link to the original post is at the bottom.

Ethereum made one mistake, talking about its future contributions before people could fully perceive them. for anyone that believes ethereum is undervalued it is my opinion you cannot comprehend abstract ideas or conceptualize what ehtereum and blockchain technology actually is.
cryptocurrencies as a digital asset are cool, fun to play with and not typically a bad investment as they are based off the value of bitcoin.
bitcoin as a form of currency has its place and will more than likely ( by means of Litecoin ) aquire a 50 billion dollar market share of cross border money transfer services current rates require 10%+ of the sent value. litecoin does this for about 1%-10% of that. (0.01%-1% and in actuality less in most cases ) divide 84 million coins (max available at production end) by 500 billion (yearly cross border money transfers) roughly $4500 per coin is the minimum value of each coin to cover just one year of money transfers. rest assured it will be higher.
ethereum is efficiency , it is balance, equality, cooperation, innovation, security, and accountability. Ethereum is progress in the name of the greater good of all mankind not just the elite. Ethereum is a social Democracy
all of this sounds nice .... which is what Ethereum promises. people need proof before investing. and that is why you will be just a moment to late. because once it's a sure thing everyone will be investing.
blockchain technology is the real use of digital assets. imagine the following, all media content can be easily published on the blockchain providing two advantages, instant alert to its previous creation if applicable (through the entire database being accessible for instant search and comparison of all published media ) instant encryption ensuring piracy is lessened ( future application software will not be downloadable its code will exist in the ethereum "cloud based" network) the media can be viewed, shared, or done with as is desired, but only to the limits permitted by its creator and only when accessed through a supported ethereum network affiliate using ethereums "Token" to powe rthe software allowing the creator of the content to share their creation. furthermore the creator is capable of issuing their own proprietary tokens that allow them to essentially grant access to their creation to anyone in posession of their "token"
The reason that you cannot comprehend Ethereum is the same reason your parents dont understand bitcoin, why your grandma will never comprehend the internet, why her mother doubted electricity, and her mother didnt see how coal could move a 50 ton train. that reason ? you are all just one generation behind in respect to grasping the concept, for which you have nothing to base its technology off of Ethereum is the next step in innovation. we all wondered what form the next leap in progress would take every great leap in technology is not recognized immediately but when initiated they cannot be stopped. the chain cannot be stopped it just moves forward. building on every advancement that comes before it.
whatare these apps ?.....
medical information will be on ethereum network.... the entire medical database of the world will be connected. acting as a living network updated instantaneously patients symptoms will have quantifiable values, vital statistics will be available for every patient that has ever had the symptoms that any given patient comes in with. by inputting the data of a patient the network uses event related probability to calculate a given set of all possible cases where the data matched with other patients ( millions of variables are considered in an instant.) to diagnose and treat patients according to the most succesful course of action as time goes on after years of trial and error the data will eventually reach a near 100% success rate. faster than we ever thought possible.
Television. cable will end see my remaining thoughts down below for why. netflix style content will replace it. tokens will be distributed. by movie producers meaning a handful of affiliates have access to the rights to distribute them. and netflix will require you to buy its token to have access.
pandora style radio tokens
gps tokens,
but why ?
by making specific tokens account for specific services we can prevent inflation. we also give a value to our money supply. remember when we had money backed by gold ? a dollar could be exchanged for its value in gold. well thats your answer. we have returned to a barter system where i can trade my own services for your services or a future promise that you can at any time redeem said token for my service, or trade for other services. ultimately our money can be thought of as bitcoin and the gold is all other coins. fiat or at least a hard money currency will always exist although two things will occur because of that. people will not be as likely to keep large amounts of money outside of the system as it will depreciate. in most cases over long periods of time. take 10 dollars out for a year and when you come back to buy the equivelent in bitcoin you will likely receive less than if it stayd in the system. where as hard currency versions of bitcoin will retain their value. that theory should hold until 2041 when all coins have been mined and by that time i would bet everyone has jumpedon board. and global currencies will have traded in their fiatmoney to make huge gains from the appreciation of bitcoin integration. i believe bitcoin will be more than an investment it is a replacement as well as a return to the gold standard.
if my outlook holds true then wewill all get an identity token. with that token you can vote on everything from what to spend the pto funds on to what roads need to be built in your city to whether that 150 million dollars should go towards researching the effects of mustard gas on purple monkeys or if it might be better served providing 2 and a half million children with water that hasnt been filled with biological waste. or maybe to give power to 20 million human beings that have lived their entire life without it.
we will have a global currency (bitcoin) and all goods and services will add to its overall marketcap. one services sucess adds to the value of all services. if you do roofing in the the summer your toens will be more valuable. if people cant afford your service then they can contribute to the mining of that service if you allow it. if yoou want to support a cause like funding research on autism then you can go and buy their coin. their service is to find a cure and if its important to people then they will continue to do so. if it is meaningless we as a society will not buy their coin and they will have to find a new job, or keep it as a hobby. either way its not up to a group of people that find it unnecessary it is the decision of the entire world as a collective entity.
many will read what i am about to say and it will cause everything i have said to be no longer looked at as credible. for this i am sorry that you are unable to think of anyone in this world but yourself, and it is people like you that have brought us to this point. socialism always failed in the worlds eyes as did communism. on paper the greatest civilization and its structure are ones in which people work together and do not worry about accumulating wealth in order to live in excess. the wealth is distributed equally, some positions which are harder to fill or require more skills will in the end offer higher pay for their tokens but only because there will be a supply and demand effect created due to its nature of less people being capable of supplying that service/good. on the flip side i believe that by the same token certain positions will ultimately demand a far higher pay. do you want to clean shit out of a porta potty ? probably not so when you need someone else to do it guess what you are going to pay that guy/girl exactly what it costs to have someone do it or you can do it yourself either way supply and demand dictates the value and the most agreed upon value between the provider and the consumer will prevail.
