A word of caution about exchanges, privacy and your permanent history on the blockchain

I had an account restricted on a major exchange this year and it's not a pleasant experience. Just wanted to share my experience, since I see so many have been through something similar in several exchange-related subreddits. My case happened at Bittrex but I think it's important to note that this may happen on any exchange, not just Bittrex. People are depositing way too much trust in these exchanges and it may come back to bite them. Here's my experience as honestly as I'm able to put it. Bittrex is technically great, contrary to what many say the system just works. Works great in fact, fast and very few glitches in many many years. I think I must've been a very early customer back when things were very informal and until 2020 I had absolutely zero problems with Bittrex. I always thought they were above the pack when it came to system security design and reliability. Despite joining when it was very early, I did full KYC and had the top tier withdrawal limit even though KYC wasn't obligatory back when I joined. I did it all formally because I wanted to have a sort of bank account I could trust, I didn't want to be jumping from exchange to exchange like some crypto traders did. I never used as much as 0.01% of this withdrawal limit, I'm small fish but it was nice to know I could move tons of BTC like the whales if I ever needed to. So I sent them all my real data, work address and so forth. Then Bittrex got moved out of USA and into some country, don't know where. Which was fine by me, I thought it was the same people behind it, doing some formality. Then one day a person with a drawing for a profile pic and some strange username decides to contact me out of nowhere using the Bittrex tech support interface. They know everything about me, but I don't know anything about them. No contact info visible, nothing. This support person sends you a statement you must sign and then based on that they begin to ask for specific documents. I wanted to keep my relationship with Bittrex, so I filled signed and returned it. Then they dived into each item in the thing requesting more documents based on each. So if you said you previously worked for ACME, they'll ask to see ACME related stuff. I said I bought Bitcoin using Bank X, so they wanted to see Bank X statements. And so on. They begin to dig into each specific item you inform. Then it downed on me that maybe I was under some formal audit, in which case I'd have the right to know so I could hire an accountant or lawyer. So I politely asked. They don't tell you anything. You don't even know who the person is on the other side, there is no identification at all of who's contacting you. You're sending all your personal informations to someone who, as far as you know, could be a cat or a dog typing on a random keyboard. So I then asked them why so much detail was needed, since I'd provided lots already. They ignore and just say thank you for your cooperation and proceded to ask for more stuff. I said fine let's do this and went along. Then they asked for specific crypto addresses for the tokens I'd used in the past. Like the address of whoever sent me some XXXX token years ago. I then thought hey man this is too much, do you need me to fax or mail you my ID or something, I'd do it but whatever I enter in there could spell trouble for me. For example, if some guy whose ETH address did something nasty, but coincidentally paid me years ago using that same address, if I gave them my address from the past, in those several years it could mean this person is now a wanted criminal and it'd spell trouble for me, who knows what the person did afterwards, then my account would be forever linked to that rogue address. I began to reflect on this and thought wait, this is not good, I could put myself into a 'bad address' database for no reason. Then I told them I would not send the crypto addresses. They said thanks let's continue the process. It felt weird overall, it just keeps going and demanding more information. I then asked for someone to speak to or somewhere physical I could go to, to talk and show that I'm a real person, they never reply anything, they just ask for more. So I finally gave up and stopped replying and they apparently restricted my account or something. I'll have to go back and reopen the ticket and request account reactivation but then they'll probably restart the same process again. I'm not really that much of a fan of crypto these days, so I'm thinking maybe it's time to call it quits. The reason I'm writing this is to let everyone know that whatever you do in crypto gets forever linked to you. You begin thinking it's some informal thing and that there's some freedom but there really isn't. You may fool around with crypto but then someone is recording everything and will demand you make everything formal in the future. When I joined Bittrex everything was more informal in crypto, even shapeshift and others allowed you to trade crypto with no ID at all, 100% anonymous. Heck even faucets gave out free Bitcoin back in the day. Then all of a sudden everything you do in these exchanges will be audited and you'll need to provide formal documents for everything you did in the past 10 years. Some anonymous operator (this isn't specific to Bittrex, all of them do it that way) with no office has all your info but you know nothing about them in return. You don't even know where these exchanges are located at all. I saw a Facebook post about Binance not even having a formal country, they're "all over t he place". Sure that sounds cool but...who do you turn to when they demand legal stuff from you? Someone out there has all your financial information but you have nothing, you have no security, no legal protection, nothing and they have everything. So, be careful. This isn't all specific to Bittrex, any exchange can and probably will do the same. Point is crypto is a formal thing and will spell trouble for you in the future. Especially since blockchain analysis is way too primitive still, your addresses could somehow end up in a bad neightborhood. The pandemic kinda reminded me of blockchain transactions, you may end up infected because you have no way to know what others have been doing while you were doing everything right.

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!

Cashing out come crypto, how to pay taxes on it

I bought some bitcoin in 2017 on GDAX. Sent it to a couple other exchanges to sell for alt currencies. Two of those exchanges are completely gone and another I don't have access to. I ended up sending it all to Binance where I did a lot of day trading in 2017/2018 but I never cashed out. After it all dropped, I put all the crypto I had into a wallet and haven't touched them since. They're rebounding now and I'm thinking of cashing it out for a house down payment. I'm worried it's going to be a problem declaring it because I never declared or paid taxes on those trades in 2017/2018, I was stupid and thought I only had to pay taxes on exchanges to fiat. I also answered no to the crypto question on my 2019 return because I was holding crypto, I never actually did anything with it (question didn't ask if you had any crypto holdings). I've never received any letters related to crypto from the IRS or any exchange.
I have records of my original transfers from fiat to bitcoin, so I know exactly what the cost basis is for all my cryptos. The problem is, from that original purchase to the crypto I have now, there's hundreds of transactions, most of which no longer have any existing records. Can I just list those original bitcoin purchases from fiat in 2017 and then my sales this year when I declare long term gains or are they going to do more digging and require me to show how the bitcoin I bought turned into several alt coins?

What is MCashchain? - Introduce about Mcashchain

What is MCashchain?

Mcashchain’s vision is to gather information and store all of them in a decentralized ledger, so as to change payment processes and financial procedures towards being cheaper, more convenient and more room for automation.
Mcashchain focuses on security, lightning-speed, efficient and of highest as well as latest technology transactions; so as to create an all-in-one platform within Midas Protocol ecosystem and global finance.

Platform structure

Throughout 11 years of development, Blockchain has evolved and been upgraded step by step, generation by generation.
Blockchain 1.0: Allows storing, exchanging properties safely and securely. Bitcoin is the pioneer.
Blockchain 2.0: The term “smart contract” was coined. ETH is the pioneer.
Blockchain 3.0: Using the strengths of the previous 2 generations, aiming to employ one specific purpose in digital products, the familiar term “Dapp” was coined.
Mcash Chain: Owns all of the strong points that were developed in each generation, optimizes the algorithms and adds the technologies to guarantee a definite ability of applying to reality; especially with blockchain’s most powerful application: DeFi.
McashChain successfully employed Mainnet, launched Mcashchain even before its introduction to the community and possessed its own coin - MCASH. Obviously, Mcashchain removed the “exists only on paper” part found in most ICO in the market.

Information:

Block closing time: 3s
Can process upto 100.000 tx

Technologies:

dApps
Smart Contract
Anonymous-on-Demand
Smart staking
Others:
POS - DAV Consensus Mechanism.
Comparing MCASH
Exchange fees close to 0.
Smart-fee technology results in cheaper transactions, yet improvised to prevent spam transactions that are dangerous to Blockchain.
Smart staking
Proof-of-Stake (PoH) Consensus Mechanism ranks the chains based on “the amount of MCASH held” and “the number of transactions processed”. Consequently, staking profits (coin digging) are attractive and fair for the stakeholders. Stakeholders - those who possess a large number of coins and Dapps developers are the 2 groups that have brought MCASH success.
Anonymous coin exchange technology - Zero M
Zero M technology allows users to anonymously exchange coins, without showing the detailed amount and information of the senders and the receivers. Yet, that does not mean Mcashchain is an anonymous blockchain, as Zero M technology allows users to switch between anonymous and normal modes whenever they want.
Smartcontract
Smart Contract technology has become a vital function in automating transactions in currently popular Blockchains such as ETH, EOS, TRON, Stellar,…
MCASH of course is no exception, Mcashchain Smart Contract brings safe, automated and optimized exchange options.
The ability to create Token
Token economy is the factor that makes ETH successful, with over 98% crypto available in the market using Dapps - decentralized applicationsứng. Mcashchain Smart Contract allows to create tokens and rewards mechanisms, in cases the token chains have several transactions.
Mcashbank – Ecosystem and DEFI
Blockchain has developed from Satoshi Nakamoto’s vision to a secured properties storing and exchanging platform not under any control. It has also entered a new phase and become the platforms that are very useful in various financial fields worldwide. Hence, the needs to create an ecosystem of applications revolving one blockchain are heightened, so as to prove the feasibility of that blockchain.
Decentralized exchange platform
All currently powerful and popular blockchain platforms possess their own DEX, such as Etherdelta and IDEX of ETH, Binance DEX, Switcheo of NEO, - just amongst others. Decentralized platforms could prove the ability of blockchain. Mcashchain also develops its own platform Unidex, as a platform supports exchanging digital properties easily.

MCASH DEFI PLATFORM

Mcashchain’s vision is to develop decentralised finance products in the future. The solution is a Mcash blockchain platform and a set of tools to build DeFi products right on Mcashchain. A complete DeFi ecosystem: Lending, saving, payment applications, automated accounting system, etc.

Why Ethereum Problems Make UMI the Flagship Among the New Generation Cryptocurrencies

Why Ethereum Problems Make UMI the Flagship Among the New Generation Cryptocurrencies

https://preview.redd.it/8skuypxp9lj51.jpg?width=1023&format=pjpg&auto=webp&s=ba5a38ba592428f92dc7c1943a780ff127132875
Ethereum cryptocurrency that comes second in terms of capitalization on the crypto market is traditionally seen as fast and profitable. However, over the last few weeks it's had a rough patch. Since early August, the network has had huge queues of transactions pending processing while fees have skyrocketed and surpassed the historical high.
The main issue though is that even fees of a few dollars per transfer don't help get rid of the“traffic jams”. The cause of this is numerous DeFi projects and a huge number of financial pyramids based on the Ethereum platform. Both generate excessive load on the network.
The situation is downright unpleasant, and our users might question whether the UMI network could face a similar challenge? We'd like to assure you it could not. The UMI network is by default protected against these problems — it cannot have “traffic jams”, fees or financial pyramids. But first things first.
How has the Ethereum network ground to a halt?
In its report dated August 4, Arcane Research that provides analysis within the field of cryptocurrency stated that over the previous week the daily size of transaction fees in the Ethereum network has surged up to a record high for over two and a half years. On August 3, the median value #%D0%9F%D1%80%D0%B8%D0%BC%D0%B5%D1%80_%D0%B8%D1%81%D0%BF%D0%BE%D0%BB%D1%8C%D0%B7%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F)of the fee amounted to $0.82, with the overall amount of transaction fees totaling $2 mln. However, it only signaled the start of real problems.
Over the next week, fees continued to grow and by August 11 the median fee value almost doubled equaling $1.57. Larry Cermak, an expert at a big analytical and news-making crypto portal The Block, wrote in his August 15 tweet that over a week the total amount of transaction fees in the Ethereum network totaled $34.5 mln, having surpassed its historical high. Meanwhile, in the Bitcoin network that is seen as too expensive the fees were almost four times lower at $9 mln.
The total fee amount paid by cryptocurrency users over a week:
  • Ethereum — $34.5 mln;
  • Bitcoin — $9 mln;
  • Monero — $2,240;
  • Tezos — $1,876;
  • Cardano — $1,615;
  • XRP — $1,138;
  • BSV — $1,102;
  • Stellar — $1,059;
  • Bitcoin Cash — $1,027;
  • UMI — $0. Let's talk about it a little later.

https://preview.redd.it/z9azd9v6alj51.png?width=1600&format=png&auto=webp&s=25c365d6e14665ecda4a2b8d19b2fc57dd5cde1e
Historical Growth Chart for Ethereum Fees. Source
The existing situation shows that Ethereum is actually not as fast and profitable as commonly cited. Additionally, this could happen to almost any cryptocurrency except UMI that charges no fees whatsoever. We will tell you why.
Why have these problems emerged?
There is nothing unoriginal: the Ethereum network simply can't handle an increased load. Arcane Research analysts consider that a principal cause of this situation is the constantly increasing number of the DeFi ecosystem projects built on the Ethereum blockchain. Their number is growing all the time which causes the overload of the network. As of August 12, the total amount of funds in DeFi applications reached $4.3 billion which is 19.5% higher than that in the past week. At the time of writing this article, the amount surged to $6.21 billion. You can see the current data here. What is the most unpleasant about DeFi protocols is that a lot of them are scam projects.
Which is not the worst part though. There is also another factor that significantly slows down the Ethereum network. There are a lot of pyramid-like projects that are built on the EOS platform and use smart contracts. One of them is SmartWay Forsage, which regularly overloads the network with a large number of transactions, causes traffic jams, and, consequently, leads to increased fees (keep in mind that Ethereum miners choose transactions with a higher commission). Vitalik Buterin, the co-founder of Ethereum, revealed his disapproval of the SmartWay Forsage methodology and asked them to "leave and not pollute Ethereum ecology in the future". However, the project is slow to do this — it continues to deceive users.
This is only the tip of the iceberg of scam projects which abounds on the EOS network –– they continually emerge, work for a while, then go down as scams and are replaced with new ones. This never-ending stream of "investment projects" based on the Ponzi scheme overloads the system. This is the reason why Adam Back, a pioneer of the crypto industry and founder of the technology company Blockstream, equated Ethereum with such infamous projects as Onecoin and Bitconnect. Adam Back's solid dig at Ethereum became the subject of much debate among crypto enthusiasts.
Of course, it all doesn't mean that Ethereum is a bad cryptocurrency. On the contrary, it has a lot of advantages over other coins. But all that has happened exposes Ethereum's faults which must be eliminated. The problem is that they may not be fixable. It is far from certain that the developers will be able to get rid of all the defects as the system has huge scalability problems.
The crypto community has to admit that Ethereum, like other first-generation cryptocurrencies, has issues with capacity, fees, and scalability and is gradually becoming obsolete.
2020 is the time for young innovative cryptocurrencies such as UMI.
UMI is the flagship of new-generation cryptocurrencies.
In real fact, any cryptocurrency could face it. Each cryptocurrency charges fees which typically surge when the network is overloaded or the price is going up. Everyone will remember 2017 when in line with price growth and the network's overload Bitcoin transaction fee reached a high of around $40.
But when it comes to UMI, it works the other way round. The UMI network's advantages are high capacity, no fees, and scaling possibilities. It uses the best and fastest crypto industry solutions and excludes all inefficient methods by default. Smart optimization in combination with the Proof-of-Authority technology operating on the master node basis enables almost instant payments.
At the stage of network testing, an incredibly high capacity was achieved:
  • up to 4,369 transactions per second;
  • up to 262,140 transactions per minute;
  • up to 15,728,400 transactions per hour;
  • up to 377,481,600 transactions per day.
Ethereum processes about 20 transactions per second. It means that the UMI network can process transactions that Ethereum processes over a year in 1 to 5 days — and with no fees.
https://preview.redd.it/rwohnov3alj51.png?width=1125&format=png&auto=webp&s=4329b75c0bd8b7a22276b529f5ca433d17a0874f
The UMI network can process transactions that Ethereum processes over a year in a few days and with no fees. More details
What is more important is that less than 0.001% of the network's overall potential is used now. The UMI network has a lot of reserve capacity and can handle hundreds of thousands of times heavier load. Moreover, with scaling possibilities, UMI can keep up with the times. The UMI code ensures the safe introduction of any upgrades — the network can be easily modified and scaled with cutting edge technology solutions. In other words, traffic jams will never pose a problem for us. UMI will instantly process all transactions, with no fees. Always.

A real-time speedometer displays the number of transactions processed by the UMI network per second. Link
Additionally, unlike Ethereum and other cryptocurrencies, the UMI's staking smart contract prevents possibilities of any pyramid schemes, meaning eliminates their negative influence. Our staking is completely safe and secured against scammers. Read more about this in our article. Any UMI staking structure could work forever. In other words, you can multiply your coins at a rate of up to 40% per month for an indefinitely long period of time.
UMI doesn't inherit the disadvantages of the first-generation cryptocurrencies. This is an innovative, carefully designed network based on state-of-the-art technologies. UMI is an ambitious step toward the future. And we're making it together right now!
Sincerely yours, UMI team

08-17 08:25 - 'Is Bitcoin a virtual currency?' (self.Bitcoin) by /u/Beneficial-Guitar-77 removed from /r/Bitcoin within 6-16min

'''
I believe that you are relatively familiar with the currency, so today I will give you a chat, bitcoin is not a virtual currency?
First of all, know about it. Bitcoin is a kind of digital currency in the form of P2P, which was first proposed by Satoshi Nakamoto.
Point-to-point transmission means a decentralized payment system.
, unlike most of the currency, the currency monetary authorities don't depend on the specific issue, it is according to the specific algorithm, through a lot of calculation, the currency economic use of the P2P network composed of many nodes in a distributed database to identify and record all transactions, and the use of cryptography security currency to ensure that each link of the design.
The second is how to buy and invest bitcoin safely.
In fact, there are a lot of cheaters, there are also a lot of pits, so still need to see other people's posts, more accumulation of experience, to participate in the discussion.
You will make fewer mistakes, because the previous generation did not make fewer mistakes.
IXX Exchange is a reliable APP that is the world's first digital asset trading community. It supports Bitcoin, Cardano, OMG, Bitcoin Cash, Ethereum, Binance Coin and hundreds of other cryptocurrencies to meet the needs of all users.
Advantages are probably rapid purchase, contract trading, safe clearing, trading efficiency, first-class service;
More practical and comfortable.
Safe buy is more important, also have a lot of forum can have relevant content, hope to be able to give everybody reference.
Because of the innovation and scarcity of Bitcoin, many people are willing to invest a lot of money to dig mines or buy bitcoin directly.

CryptocurrencyCheckout.com - An alternative to 1upcoin.com / coinbase for donations that shows up with streamlabs alerts.

Hi guys, So after some digging on google, I found out about cryptocurrencycheckout.com. I do not work for them. I've constantly been looking for an alternative to 1upcoin.com because users of 1upcoin.com must go through coinbase and coinbase charges outrageous fees.
From what I have seen in their discord channel so far they seem legit and they have been rather helpful and responsive.
setup guide here: https://cryptocurrencycheckout.com/guides/twitch

Important: Once you set your bitcoin / ethereum / litecoin / cryptocurrency wallet addresses, you may NOT change them. This is a security measure. If your cryptocurrencycheckout account becomes compromised (as in someone steals it), the hacker or malicious actor in question, cannot simply change your donation address to his own BTC/LTC/ETH address and thus can no longer steal your crypto. However, this also means that if you lose access to your cryptocurrencycheckout account, you will have to set up a new one.

Customer support? https://cryptocurrencycheckout.com/contact
Also, the wallet addresses you set up with cryptocurrencycheckout belongs to the exchanges you already use (binance, kraken, kucoin, etc.). That way if you have difficulty accessing your wallet you can just contact customer support on those exchanges for your own exchange to resolve the issue quickly.
EDIT: I have tested this myself and it seems to work just fine. At least, test donations seem to work just fine.

Why i’m bullish on Zilliqa (long read)

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

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

Appear to have lost my BTC on nano ledger S, since updating my firmware from 1.3.1 to 1.6 and upgrading to Ledger Live. Anyone have the same problem or any possible solutions please?

I have not used my ledger Nano Ledger S in over a year so I had to update the firmware from 1.3.1 to 1.6 and I had to download Ledger Live to access my crypto on it as per the instructions on: https://support.ledger.com/hc/en-us/articles/360023518653-Solutions-to-most-common-issues
Although this was not a simple task, everything seemed to run smoothly. I did not need to enter my word seed, only 4 digit passcode. My ETH and XRP showed up as I left it one year ago, however I also had BTC on there which does not show up. It's also quite confusing as to why there is two Bitcoin chains (native segwit and segwit). Regardless, the Bitcoin amount does not show up on either.
I've also tried clearing the cache in Ledger Live but this did not solve it.
I was wondering wether it is is worth trying to recover the BTC by starting my Ledger Nano S as a new device and entering the word seeds. Or if there is any other method?
Unfortunately, I did not note down the public BTC address but I think I can dig it out if really needed (will have to scroll through Coinbase Pro/Binance).
Note, I have tried contacting the ledger team but have not yet had any reply.
Thanks for your help.

To 100 Principle Representatives - #8

A NanoCharts driven update for those who want to take control of their Nano and select a rep for their voting weight.
For new community members, its worth pointing towards this video to learn about the ORV consensus system that Nano uses: https://youtu.be/LZ8TZFfYDcY
Ideally you are taking your coins off Binance (as number 1 rep in terms of weight and you can’t pick a rep there) or removing weight from another larger rep/or a rep controlled by a large entity. Most wallets let you pick a representative, and are even starting to provide additional functionality; surprisingly the NWC mobile apps don’t allow for representative selection right now.
Finding a rep can be easy using two main sources:
Nanocharts is a useful view from top reps in terms of weight and below; if you scroll down around the 133K Nano mark you’ll potentially find some reps who only need a but more weight to become a RR. NanoCharts also can help you find a rep, using its ‘need a representative’ function near the top of the page.
My Nano Ninja itself is linked from NanoCharts and gives users a great source for further digging into a reps details. Its pioneered the scoring system to help users choose reps, and has even forked the ever popular NanoVault with NinjaVault (which integrates some key functions such as the scoring system).
https://arewedecentralizedyet.com also gives us a wider perspective on decentralisation against other cryptos. I think the number of nodes we have without a monetary incentive is a good stat... and the it draws on the key Nakamoto coefficient from https://repnode.org/representatives/nakamoto (how many entities could collude to form a majority on the network - this number is ideally getting bigger). Unfortunately, they don't always pull the latest stats into their main screen.
Further help on Nano decentralisation could be found in the #decentralise channel on Nano Discord.

As a general rule, personally I would consider the following when picking a rep:

Current Status

We currently have 88 Principal Representatives (RR) that help secure the network (that have over around 133K Nano voting weight) and not all of those are online right now. It would be a good milestone to have 100 RRs, and even better to have 100 RRs that are online.
Since my last update (roughly) or worth mentioning:

Notable Representatives (IMO) Not Rebroadcasting

https://mynano.ninja/account/xrb_34jodkgq6dko31s4hj7a18kf6ax8ax8n6c98eb5jqq56s9kt7bi9g4fidwbx
One I’m involved in and driven by a great little team of Nano (and Quake) enthusiasts. Setup by the indomitable jayycox (so its newness isn’t a concern for me). After a recent push, this is now only 28K Nano away from becoming a rebroadcasting rep.
Most importantly for me, this would be a good presence in South America (see https://mynano.ninja/map) if we can get this at PR status.
A newcomer to the Nano ecosystem, but their hardware seems pretty impressive and they intend to stick around the Nano ecosystem.

It would be another presence in South America.

Contribution quantifying model and prevent centralization of power

Original post: https://medium.com/iconviet/contribution-quantifying-model-and-prevent-centralization-of-power-f4d0b70a196
Solving contribution puzzle and introduction of ContributionDAO. How it could deal with the public enemy of every blockchain ecosystem: centralization of power.
It explores following topics:
I wrote with the love for ICON and many years of experience in crypto/blockchain space as well as a long exposure to political theory. You know, blockchain is a beautiful combination of economic, politic and technology. But it will become ugly if not being done properly in the first days.

Can contribution be quantified ?

This question should be started with another one: how do we define contribution ? We cannot quantify something without identifying it first.
But there are many answers, very biased ones you know. Anyway, at the end of the day, we must come to a consensus on how we could identify contribution. In my observation, the consensus is "anything help to bring value to ICON network, it could be counted as contribution"
Now here comes another question, how do we know that some activity will bring value to ICON network ( and ICX price ) ? Well, just use common sense alone, I can make a list like following
That is my list, there are many more for sure, it depends on your experience and perspective. As long as you can explain how your activity could bring value to ICON, and if community accept it, then it is contribution. Subjectivity is the nature of the game.
At this point, assume that we can identify contribution ( or we think something may be a contribution ), how to quantify them ? How to determine how big, how important, how significant that contribution is ? Again, subjectivity is still around here. There is no universal truth at all. Each ICONist probably has a subjective view on the significance of some specific contribution. It makes us hard to quantify contribution reliably, so what should we do ?

A heuristic technique to quantify contribution

So, do we must live with it ? Even ICON Foundation does not give us any strong set of rule on this quantification problem. Is it that sad ? Is it the end ?
Not really, no way we are in dead end here, we never surrender. In fact, I strongly believe that we just need to use common sense and community wisdom, combine with verifiable proof of finished contribution and one well designed DAO for overseeing them, we could come to a good enough heuristic method to quantify contribution.
Wait a minute, what does heuristic mean ?
"A heuristic technique, often called simply a heuristic, is any approach to problem solving or self-discovery that employs a practical method that is not guaranteed to be optimal, perfect or rational, but instead sufficient for reaching an immediate goal." - Wikipedia

A special DAO for overseeing contribution ( ContributionDAO )

To quantify PRep contribution, the heuristic framework could be like this
ContributionDAO does not guarantee an absolute objective quantification of contributions, but it could be a useful weak-subjective quantitative tool for community to determine the significance of contributions done by PReps. In the beginning, all ICONists have the right to evaluate and vote for the meaningful contributions, but if they keep voting blindly, irresponsibly and against majority, their CNTR holding will be burnt to zero gradually and they will lose their right eventually.
Note that, beside the initial CNTR distribution by airdrop, anyone can still buy CNTR on open market if there is seller, but that is another story I will go more deeper in ContributionDAO light paper. Just a hint, it relates to governance economic.
Yeah, governance activities could form a whole economy of their own. This game will be interesting.

Every form of centralization is disfavored in public networks

Why ?
In simplest explanation, community support is de facto force for the success of every public open projects ( public blockchain is one of them ). In order to secure community support, the project must belong to community first. By nature, centralization in all forms is against community interest, it will result in gradually decreasing of community activity and ultimately, the dead of project ( or zombie state )
If you still have a vague idea on the importance of community, please take a look at Bitcoin and Ethereum, they are the ones with strongest community support so far. Developer adoption will come naturally with huge community and decentralization. We all see the fact that no one want to build on a centralized authoritarian network.
\* If someone want to bring Binance as counter argument here, please consider the short term benefit of being listed on Binance itself, it has nothing to do with the merit of a truly open and decentralized blockchain project. You know what I mean, right ?*

The power of early adopter and contributor

There are always pioneers in every community, nothing new here. There must be first contributors and adopters who take risk and invest their time into something still being in nascent stage. Yeah, those people really deserve a huge reward.
But the problem here is, that "huge reward" is usually come in form of soft power. It means they possess a huge influence to community. Sometime, it is the hard power, especially in blockchain, if they hold a lot of token and being the owner of big business running on the network. Either accidentally or intentionally, the power is centralized in their hand.
Note that, I don't assert them to be bad actor here, absolutely no. In fact, they could be good actor and still possess a huge power somehow. Anyway, centralization of power is still centralization.

What we could do in early stages to avoid the fate of crypto-dystopia

In my opinion, the first thing we as ICONist should do is make sure we vote for the right PReps as they are the ones with immense power on ICON network. However, wisely voting alone is not enough, we must make sure power is not centralized in their hand ( even for good and ethical PReps ).
With ContributionDAO, we will soon have a single one portal which provide more comprehensive and more details data source to research about PRep contribution. The good news is that portal will be governed in a decentralized manner from the first day.
No more time consuming digging and searching for contribution detail of PReps, it will save a lot of time when there are more and more PReps joining the game.
I hope that ContributionDAO could help more ICONists to participate in ICON network governance by providing better tool and data source, as well as economic incentive. The more ICONists actively research and vote for right PReps, the better ICON network will be in long term.
It is time for wrapping everything up. We should know that ContributionDAO is just a tool, ultimately everything is up to ICONists. If ICONists choose to play selfishly for short term benefit, nothing can save ICON from destruction. But if we - all ICONists - decide to care more about ICON future, I believe ContributionDAO will be able to help us.
I am a member of ICONVIET team and also an ICONist myself. I and ICONVIET strongly believe that beside DApps building and business development, contribution in governance design and proposal is also very important. Therefore, ContributionDAO will be one of our main projects after decentralization.
** UPDATE_1, thank everyone for feedbacks :)
The purpose of ContributionDAO is make sure every contribution is showed clearly, compactly and quantitatively. It can help to avoid the vague effect of heavily-marketing-buzzword when PReps announce their contribution.
It could be used as a tool for official democratic voting provided by ICON which reflect the final decision of ICONists.
Thank you for your support :)

Investigating the $1B Bitcoins on the move from a SilkRoad related wallet

Investigating the $1B Bitcoins on the move from a SilkRoad related wallet
2 days ago, I reported that a SilkRoad related wallet containing about $1B worth of Bitcoins (111,114 $BTC and the same amount of $BCH and of other Bitcoin forks) was on the move after 4 years and 5 months of inactivity : https://www.reddit.com/Bitcoin/comments/9bfnff/near_1b_are_currently_on_the_move_from_a_silkroad/

Today, I will dig a little bit more into this wallet activity.

Below you will find a graph representation of the transactions sent over time from the original 111,114-BTC wallet to the most recent wallets which have received some of the coins. Each branch represent a sequence of transactions sent through several wallets.

Red nodes indicate the most recent transactions (< 1 month), blue nodes indicate quite recent ones (<1 year) and green nodes are the older ones ( > 1 year).

https://preview.redd.it/jjhfpb4udhj11.png?width=2233&format=png&auto=webp&s=7a369b73dfbe4601e05608f1aae36aff24a4d52e

  • Picture 2: original coins are currently transferred on Binance wallet, in fact it is a major end-point/aggregate of transactions originated from the 111,114-BTC wallet (1NDyJtNTjmwk5xPNhjgAMu4HDHigtobu1s).
https://preview.redd.it/7novcf2wdhj11.png?width=2222&format=png&auto=webp&s=d0c429674a70bf2baf32c4ecc9c4475a1d43ad7e

https://preview.redd.it/9ungmsexdhj11.png?width=1620&format=png&auto=webp&s=079fcf54605e88debe0cac297e492785b7cc73ed

  • Picture 4: funds are currently actively mixed, you can see a chain of red nodes with no other purpose than transferring n time the coins and splitting/mixing it a bit (3Ah15skNb8R1teRWs6h2Q2vRywkLJWUhhb).​
https://preview.redd.it/9lzr31n0ehj11.png?width=2227&format=png&auto=webp&s=ade9fcf046e86a595e47f8c196df3abcb28866d3

So it's now obvious that the wallet's owner :
  1. is very actively splitting his original 111,114 BTC this past month (a lot of transactions are very recent, see the amount of red nodes on the graph);
  2. some of this funds are currently being sold on Binance (picture 2 and 3);
  3. is very actively in the process of mixing, hiding and making difficult to track his coins (picture 4).
Is the owner going to sell all his coins? How do you think this can impact the market?

Update 1
Following the request of u/btc-reddit, below you will find the graph that marks with red dots the wallets which have been active in the past 24h. At least 88 BTC have been transferred in the last 24h to Binance wallet: 18afibtW5NLMqMwCZD6yt1qhkmEbrfa3QF , 1M2stLGnZGi9XhB2sqTwFfcSfxZhzYKHs6 , 15jFKpCBfHN599TopLPQYdv2aNCRZSUw2r , 1F1EWmLJtYUA1yvDGRBQ6Z6Zjp33ci9EZX , 1M2stLGnZGi9XhB2sqTwFfcSfxZhzYKHs6 ...

​Furthermore, more than 2,980 BTC have been transferred to Binance wallet in August 2018, certainly to be sold or exchanged with other currencies, which represents 3% of the original wallet.
That's more than $20M worth of bitcoin at current price, it definitely can have impacted the overall price this month.
Most of it was sold after August 12th, which corresponds to the start of an increase in Bitcoin price interestingly:

Update 2
​This address is also heavily involved in this graph: 1NyfNYAXZ76VNdvxUUVxdbhWFQGa7QDjTn. It saw 73,673 BTC go through it (only 350 BTC originated from the wallet we are studying here though), in a little bit more than a year.
https://preview.redd.it/sbkx1etviij11.png?width=2041&format=png&auto=webp&s=05d81143196dce1c33dd2d6ea6695900ddd8d0d9

Update 3
This address 3D83uPnvodCLpwedooiRrLjdQ9pcFVZF32 is part of the graph and is multiplexing a lot of coins, about 175 BTC in small chunks < 1 BTC.​

Update 4
This is a more refined and complete version of the graph (the yellow nodes indicate transactions activity < 1 month). I let you find where is Binance wallet located ;-)
Obvious, isn't it!
https://preview.redd.it/y9e8tdlodkj11.png?width=2277&format=png&auto=webp&s=386fc91353b6c67d9ce8d6970c6c4bc1b7416a1a

Update 5
$110M worth of Bitcoins ​transferred Bitfinex and Binance: https://www.reddit.com/Bitcoin/comments/9ceb5v/1b_bitcoins_on_the_move_owner_transfers_100m_to/

Update 6
$1B bitcoins on the move: MtGox vs SilkRoad origin and BTC crash discussed
MtGox vs SilkRoad origin and September 6th BTC price impact is now discussed here: https://www.reddit.com/btc/comments/9dvaj1b_bitcoins_on_the_move_mtgox_vs_silkroad_origin/

Binance airdrop / giveway scams

DISCLAIMER: this is not Binance's fault, more Google's for not filtering their news feed.
This shit just popped in my Android news feed. At first I was like - holy crap, that's insane! But then I recognized the classic scam, so I decided to dig. I found multiple scam channels that post videos like that, and some of these channels have a ridiculous number of subscribers:
1) 256K subs: https://www.youtube.com/uselongjuniovideos (only 9K views, LOL!)
2) https://www.youtube.com/channel/UCW-l49hIAqEltHb37JdQ0Ig/videos (no sub info, but 22M views) 3) https://www.youtube.com/channel/UCfhU1sCkUUxdhN6L9TnYTdQ/videos
4) 16K subs: https://www.youtube.com/usepetpiggiesuk/videos (10M views, content not related to Binance at all) 5) 1.2K subs: https://www.youtube.com/channel/UC40zaINaUvp00m6FRfRFtnQ (only 4K views!)
The video in my feed, 18K people are watching it now. It makes sense, since it somehow got into the Android news feed. Google sucks at filtering this shit.
At least it looks like nobody is falling for this scam. The address in question is 3MQaTYz7rMxukV4DfEbXmMfCWUYytc2faL.

Just spent about 12 hours figuring out my tax liabilities with bitcoin.tax. Here is how it went...

I have been reading more lately about all the US tax liabilities that can come into play in the crypto world and have started worrying about how much I would owe for 2017. I was starting to lose some sleep on the matter and finally decided to organize all of my activity once and for all. I figured I'd write this post for other people who might want to find out what I have learned in this process. I am filing in the US, but some of this might apply to people in other countries as well.
If you have just bought and HODL'd then it will probably be much simpler for you. But if you have done ICOs and any trading and are worried about this stuff, don't worry too much. Its totally possible to get yourself organized with a little bit of work.
Background
Bought my first ETH in Feb '17 from Coinbase and since then:
The Tools
The best place to get started is bitcoin.tax
Referral Link
Normal Link
I signed up for the 1 year plan for $19.95 (they also accept crypto) and believe me its worth every penny. You can use it for free, but are limited to 100 items (I ended up having > 1500). It really does almost everything for you, so you don't have to worry about figuring out the cost basis yourself. The only time USD was involved was buying via coinbase, everything else was handled as a token to token trade.
Microsoft Excel or Google Sheets is a must if you are doing any trading on the non-supported exchanges because you might have to massage the data into the correct format.
Etherscan
Unfortunately, for some trades and the ICOs, I had to go directly to Etherscan to track down the data.
DeltaBalances
This is a lifesaver for tracking trades made on ED. I wasn't able to get the export feature working, but copy/pasting the table into Excel was fine.
Html Table to CSV
If you are having trouble copy/pasting table data this comes in handy. You can just copy the raw table HTML from Chrome Dev Tools and get a nice CSV.
Exchanges
I am only going to list the exchanges I use and how I was able to get the data into bitcoin.tax. But regardless of the method, make sure you verify all the data that was imported. The system did a bad import on my Bitfinex data and I had to wipe it and reimport because it was missing a bunch of rows.
All the importing is done on the trading tab of bitcoin.tax. Some exchanges require you to download a .csv file from the exchange website, and some have direct API access. Just follow the tutorials on bitcoin.tax for each exchange.
The Easy Ones
Bitcoin.tax supports API data pulls for these exchanges: Bitfinex, Coinbase, GDAX, Kraken. For these, I still recommend going to the exchanges and downloading a copy of your history for your personal records.
You need to login to the exchange and download trade history and then use bitcoin.tax's import tool for these: Binance, Bittrex, Poloniex
The Tough Ones
Trades made on Etherdelta present a bit of a challenge. There is no direct import into bitcoin.tax so you will have to manually compile a CSV and import it to their system. They give you a template to follow with the required data and it will require a bit of "massaging" to get the ED data to the correct format. For this is it extremely helpful to use DeltaBalances. For each wallet you use you will need to check the trade history and go back a sufficient number of days to cover your trading history. Warning, it might take a long time for this process to finish and it isn't 100% reliable. When I ran it, it needed to download > 200MB worth of data for the 260 days I went back. My suggestion is to run it a few times to validate the results. You will need to run it for each wallet you use to trade on ED. Once you get the results, you can try copy/paste the table into Excel and then format the columns to match.
Liqui was the biggest pain in the ass of them all. If you traded a lot on Liqui, be prepared for some pain because they have no export and only show you the history of 1 pair at a time (and only the last 30 trades!). Liqui has over 250 trading pairs so if you forgot what you traded, you will tediously have to go through each pair to check. I couldn't bear this, so I ended up coding a custom script to query all 250 trading pairs and dump out the data for me, then I had to import that into Excel and format it to match the bitcoin.tax template.
Kucoin wasn't too bad. They don't have an export function, but you can copy paste the tables into Excel and massage the data there.
I did a few trades with OasisDEX but when I went there it didn't have any of my history, so I had to manually cobble that together from looking at Etherscan. Luckily it was only a few trades or else this would have been very tedious.
ICOs
Like I mentioned, I participated in something like 20 ICOs this last year. Unfortunately I have no records of any of them. In bitcoin.tax I handled these as just another trade. In order to track down the ICOs I participated in, I was forced to use Etherscan and go through my whole transaction history looking for them. In order to add the trades manually in bitcoin.tax you need the Date, the # of ETH you spent and the # of tokens you received. It's not super difficult, but just very tedious. One that threw me for a curve ball was RedPulse. This was a NEO ICO, but adding a trade manually doesn't yet support NEO as a currency. The workaround for this is putting it into a CSV and importing it that way. In fact, if I was to do this again, I would have built a CSV for all the ICOs and just imported it that way rather than inputting them one-by-one.
Airdrops
I treated airdrops as "Gifts/Tips" under the income tab. I had to find these through Etherscan.
Verifying the data
In order to verify that all seemed right and there are no problems, there are two things that I was working toward:
Conclusion
Overall, although there was some tedious parts, this was a really good exercise. Going through my entire history gave me some great insight on how my strategies played out (ICOs were great / I suck at trading). As far as the taxes themselves, it turned out to be a lot more than I was expecting, but considering the gains I am not too sad. Going into this next year I am going to make some changes. First of all, I will probably stop trading as much. It just wasn't that successful for me and created a lot of work and taxes on top of that. Secondly, I really want to try and stay away from exchanges that don't (or don't plan to) offer history exports. Third, I will probably hold most of my unsold ICOs for at least a year so as not to be liable for short term gains. Lastly, I will keep better records as I go along so I don't have to do so much digging for next tax season.
I hope this can help some of you guys figure this out and I would love to hear any additional tips from those of you who have gone through this.
Edit: A couple other hiccups that I just remembered. Some tokens change their symbol, this can cause some havoc, I had done some trades in MyriadCoin as MYR then it changed to something else and it got all wacky. Updating the old token symbol to the new one seemed to do the trick. Also, to add to the Liqui woes, I had bought some BCAP way back in the day, but it got delisted so there is no way I found through the UI to get that information. The only way I found out I had actually done that trade was that the script I coded iterated through every possible trading pair and only then it was uncovered.
Edit #2: I got a request for the liqui ruby script

Binance Replayed Bitcoin Cash Deposit?

So I finally got around to digging up my private keys from my old Bitcoin wallet so I could get access to my Bitcoin Cash. I deposited the Cash to Binance and sold it. Now I see they replayed the transaction for Bitcoin SV? Or does Bitcoin SV do that for all Bitcoin Cash transactions? I withdrew the SV again, because Binance doesn't allow trading with them.
I wasn't planning on doing anything with the SV coins, I was planning on just letting them sit. Of course it's better that Binance replayed the transactions and gave me access, rather than some malicious actor, but I found it really weird that Binance just did this without asking or even telling me that they did it. I didn't even get a warning, after nor before.
Is this expected behaviour?
