What is required to build your own Bitcoin Exchange ...
Ultimate glossary of crypto currency terms, acronyms and abbreviations
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:
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.
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.
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.
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!
UYT Main-Net pre-launching AMA successfully completed with a blast
7 pm, 29th September 2020 Beijing time the UYT Main-Net pre-launching AMA successfully completed with a blast! Here is a full record of the AMA: Host: Hello everyone, it’s a great honor to host the first AMA of UYT network in China. Today, we have invited the person in charge of UYT Dao. Let’s ask Mr. Woo to introduce himself Woo: Hello, I’m Ben. I’ve met you in the previous global live broadcast. I’m the director of UYT Dao and the founder of IGNISVC. At present, I’m the CEO of the TKNT foundation and have been engaged in the blockchain industry. Q1. At present, different types of blockchains have emerged, but cross-chain interaction is still suffering a lot. In your opinion, what is the necessity and significance of cross-chain? Answer: The full name of UYT is to unite all your tokens, which is to integrate all public chains and increase the liquidity of the whole industry. Our purpose is not to create another public chain, but to become a platform for the exchange of value, technology, and resources of all public chains. What we need to solve is that each individual chain can circulate with each other. The full name of UYT is to unite all your tokens, which is to integrate all public chains and increase the liquidity of the whole industry. Our purpose is not to create another public chain, but to become a platform for the exchange of value, technology, and resources of all public chains. What we need to solve is that each individual chain can circulate with each other. Q2. The founder of Ethereum, V Shen, once wrote a cross-chain operation report for bank alliance chain R3, which mentioned three cross-chain methods. Which one does UYT belong to? Can you briefly introduce the cross-chain solution of UYT? Answer: In Vitalik’s cross-chain report, there are three main cross-chain methods. The first is that both parties do not know that they are crossing the chain, or that they cannot “read” each other, such as the centralized exchange. The second way is that one of the links can read other chains, such as side-chain / relay chain. That is, a can read B, and B cannot read a; The third is that both a and B can read each other’s, which can achieve the value and information exchange between a, B, and the platform. UYT belongs to the third kind. Our new official website will be online soon. Here are a few simple points: first of all, the architecture of UYT includes relay chain, parachain, parathreads, and bridges. In terms of ductility, it has exceeded almost all the public chains currently online. In the UYT network, there are four kinds of consensus participants, namely collector, fisherman, nominator, and validator. The characteristics of this model are: first, all people can participate without loss. Secondly, as long as anyone makes more contribution to the ecology, he will get more rewards, otherwise, he will receive corresponding punishment. The underlying layer of UYT is the substrate, which uses the rust programming language. Rust is committed to becoming a programming language that can solve the problems of high concurrency and high-security systems elegantly. This is also a great advantage that we are different from other blockchain projects in technology. Q3. What are the roles in the UYT network? What are their respective functions? Answer: After the main network of UYT is online, there will be four roles: collector, fisherman, nominator, and validator, which is totally different from the current system of the test network. The collector, in short, is responsible for collecting all kinds of information in the parallel chain and packaging the information to the verifier. Fishermen, to put it bluntly, is fishing law enforcement, which specifically checks out malicious acts and gets rewards after being checked out. The nominator, in fact, is a group of rights and interests. The verifier is its representative, and they entrust the deposit to the verifier. Verifier, package new blocks in the network. It must mortgage enough deposits and run a relay chain client on a highly available and high bandwidth machine. It can be understood as a mining pool. It can also be understood as the node in the current UYT DAPP. Q4. What is the mining mechanism of the UYT network? The only way to obtain UYT after its issuance is to participate in mining activities. In the initial stage, the daily constant output times of UYT are set to 1440000, and the cycle of bitcoin is halved. Mining rewards can be obtained in the following five ways: 1) Asset pledge mapping mining 2) Become the intermediate chain node of uyt network 3) Recommendation and reward mechanism 4) Voting reward 5) UYT network Dao will take out 10% of gas revenue from block packaging for community construction and reward of excellent community personnel Q5. The rise and fall of the blockchain are very fast. In order to give investors confidence, is there a detailed development plan, implementation steps, and application direction of UYT network in the next few months? Answer: UYT Network test network has been running stably for a year. After the main network is launched, all mechanisms will undergo major changes. The relationship between the UYT test network and the main network can be understood as the relationship between KSM (dot test network) and dot the main network, and the feasibility of the technology can be reflected more quickly by the UYT test network because of its faster timeliness and all future technology updates Some will move to the main network after the stable operation of the test network. In order to give users a better experience and give more rewards to excellent nodes, all Dao organizers are working hard for it. The development team has completed the cross-chain of bitcoin and some high-quality Ethereum based tokens in the early stage, and now the code has all been open source. For other mainstream currencies, community members can apply for funds to develop. In order to develop the ecology and make a better technical reserve, we will set up a special ecological development fund when the main network goes online. The transfer bridge is our key funding direction. The maximum application amount of a team is as high as 100000 US dollars. In addition, if other public chains want to connect to UYT, they will get technical support. In order to encourage developers to participate in ecological construction, Dao also launched a series of grants to support development. Developers can directly pull the better applications on Eth and EOS directly, or develop new products according to their own advantages. These directions are now the focus of funding. Due to the early online testing time of uyt network, it is based on the earlier version of substrate1.0. The on-chain governance mode can only be realized after the upgrade of 2.0 is completed. At present, the upgrading work is going on steadily, and the on-chain governance will be implemented in the main network with the launch of the uyt main network. As a heterogeneous cross-chain solution with high scalability and scalability, UYT network can perfectly bridge the parallel encryption system and its encryption assets in theory, and its wide applicability in the future can be expected. Therefore, we do not limit the areas where UYT network will play its advantages and roles. But in the general direction, there will be mainly DEFI and DEX ecological plates. From the industry, it can cover a wide range of fields, not only finance but also games, entertainment, shopping malls, real estate, and so on. Q6、How can UYT help DEFI? Answer: UYT network can not only link different public chains but also make parallel chains independent and interlinked. Just like the ACALA project some time ago, it has successfully obtained Pantera capital’s $7 million saft agreement. Although the concept of DEFI is very popular now, all DEFI products are still in the ecology of each public chain, and the cross-chain DEFI ecology has not been developed. UYT is to achieve cross-chain communication, value exchange, and develop truly decentralized financial services and products. For example, cross-chain decentralized flash cash, cross-chain asset support, cross-chain decentralized lending, Oracle machine, and other products. At present, our technical team is also speeding up the construction of infrastructure suitable for the landing of more DEFI products and services and is committed to creating a real cross-chain DEFI ecology, which is only a small step of UYT’s future plan. Q7、TKNT should be one of the hottest projects in the UYT ecosystem recently. Please give us a brief introduction to the TKNT project and the value of TKNT in the UYT ecosystem. Why can TKNT increase 400 times in 7 days? And what is the cooperative relationship between UTC and TKNT? Answer: I will answer each project from the technical and resource aspects. Let’s first introduce UTC. UTC is the token of Copernican network and the first project of UYT game entertainment ecology. In the future, it will be responsible for linking. Due to the high-quality public chain in the entertainment industry, because of the limited slots of UYT, each field will seek a high-quality partner and help the partner become the secondary relay chain of UYT. After the main network of UYT goes online, many chains will want to access UYT Greater value circulation, due to the limited external slots of UYT, the cost is also very high. At this time, you can choose to connect to UTC first, and then connect UTC to UYT. With more and more links with UYT, it will gradually evolve into a secondary relay chain of UYT network. UTC’s resources, online and offline, offline payment and offline entity applications, also have a very large community base. The ecological partners have very good operation experience in the game industry. They will use blockchain technology to change the whole game entertainment industry to make it more transparent and fair. At the same time, there are enough entity consumption scenarios. This is also UYT Because of the reason why the network chose to cooperate with it, the UTC project has been supported by the UYT ecological fund. The support fund includes that after the main network is launched, it will also be the first ecological cooperation project supported by UYT. Because of the online time of the main network of UYT, UTC can’t directly form a chain at present and will give priority to issuing on Ethereum. TKNT is a new concept project TKN.com TKN is the largest online centralized guessing game platform in the world at present. TKNT mixes bet mining and DEFI, so it can carry out fixed mining through platform games, build a system that can realize game participation and in application payment in all Dapps based on ERC20, and combine with various financial services. The reason why TKNT has created a myth of 400 times in 7 days is that the TkN platform has a buyback plan. As we all know, the online quiz game entertainment platform has an amazing profit. Every quarter, the profit will be used to buyback. The strong profit support has led to the huge increase of token. In the future, all users can use UTC to participate in TkN games. Therefore, the main network of UYT is that Line is also of great significance to TKNT. With the maturity of UYT ecology and technology, TKNT can have a more powerful performance. If TKNT wants to link more public chains, it needs to access UYT network, and realize a bigger vision with cross-chain interaction of UYT. After TKNT was launched on the exchange, the highest price has risen to $14, and now it has dropped to about $2.50. You will see that it will once again set a record high and create greater miracles. You will also see that $3 will be the best buying point for TKNT, because there will be several major moves in TKNT, and the global MLM plan will be launched on October 7 in Korea, China, and other countries There will be many marketing teams in Europe to promote TKNT, including DAPP.com As a shareholder of TkN, TKNT will also make every effort to promote TKNT. Secondly, TKNT will be launched next month on the largest digital currency exchange in South Korea, and Chinese users will see the shadow of TKNT on Binance in November. Of course, the decentralized trading platform of UYT will also be launched in the future. Q8. What is the significance of the launch of UYT’s main network for the industry and ecology? Answer: UYT is one of the few cross-chain platform projects in the industry at present. There are many public chains and coin issuing projects. Why? Because of less work, more money. However, there are very high technical and capital requirements for cross-chain and platform. This barrier is very high, so almost no project side is willing to do this. But once this is done, it will be of great significance to the whole industry of digital currency and blockchain. Because it will subvert the current situation of the whole currency circle and chain circle acting on their own, and the painting land is king. Let each independent ecosystem achieve a truly decentralized and trust-free cooperative relationship. This huge change will promote the whole industry to develop into a healthy and virtuous circle macro ecosystem. Q9. The slogan of many project supporters is that UYT should surpass Ethereum. What is the difference in technology between UYT network and Ethereum? Answer: Thank you so much for supporting UYT. In fact, the correct understanding is that UYT is the next era of Ethereum. First of all, UYT has a different vision from Ethereum. Before the emergence of UYT, Ethereum, and EOS, no matter how well they developed, belonged to the era of a single chain. The popular metaphor is a LAN. However, UYT can realize the interoperability of each chain and bring the blockchain into the Internet era. Secondly, UYT is far superior to Ethereum in technology. It mainly includes three aspects: shared security, heterogeneous cross-chain, and no fork upgrade. In the case that Ethereum 2.0 has not been implemented, UYT is the most friendly bottom layer for the DFI projects and other Dapps on Ethereum. Now, the hair chain architecture substrate of UYT is compatible with Ethereum smart contract language solidity, so eth developers can easily migrate their smart contracts to UYT. Up to now, there is no good solution to the congestion problem of Ethereum, while UYT network not only solves the network congestion problem. What’s more, UYT can easily realize one-click online upgrade, instead of having to redeploy a set of contracts on Ethereum for each version upgraded and then require users to follow them to migrate the original assets from the old contract to the new contract. Developers can quickly and flexibly iterate their own protocols to change their application solutions according to the situation, so as to serve more users and solve more problems. At the same time, they can also repair the loopholes in the contract very quickly. In the case of hacker attacks, they can also solve the hacker stealing money and a series of other problems through parallel chain management. We can find that for Ethereum, UYT not only solves the congestion problem we see in front of us but also provides the most important infrastructure for the future applications such as DFI on Ethereum to truly mature into an open financial application that can serve all people. It also opens the Web 3.0 era of the blockchain industry. In terms of market value, Ethereum currently has a strong ecological construction, with a market value of US $40 billion. UYT will also focus on the development of this aspect after the main network goes online. No matter in terms of market value or ecological construction, I have enough confidence in UYT, after all, we are fully prepared. Q10. What is the progress of the ecological construction of UYT? What opportunities do current ecological partners see in UYT or what changes may be brought about by UYT ecology? Answer: After the main network of UYT goes online, there will be a series of ecological construction actions, and more attention will be paid to establishing contact with traditional partners. Cross-chain decentralized flash cash, cross-chain asset support, cross-chain decentralized lending, Oracle machine, and other products will also be the key cooperation direction of UYT. UYT will give priority to the game and entertainment industry because this industry is most easily subverted by blockchain. As the ecological construction of UYT gets bigger and bigger, the future slots will become more and more expensive. The earlier you join UYT ecology, you will get more support from the ecological fund because the ecological fund is also limited. From the perspective of token value-added, all the project parties will cooperate with the project side in the future, and the project side needs to pledge a certain number of UYT to bid for slots, except for ecological rewards, others need to be purchased from market transactions. The difference between the pledge here and the pledge we understand is that the UYT of the ecological partner participating in the auction pledge cannot enjoy the computing power for mining. UYT main network has several opportunities for Eco partners to look forward to, the first point is bitcoin, bitcoin will be later than other assets late, but eventually, all the bubble and value will return to BTC, after the wave of DeFi bubble elimination, the focus will be very much in the bitcoin. UYT ecology can provide a more mature bottom layer for defi. In addition, now Ethereum’s DEFI is that of Ethereum and ERC 20 tokens, and the outbreak point of bitcoin has not yet arrived. Therefore, the DEFI of UYT ecology may be the next opportunity, which is a good opportunity for everyone. The second opportunity is that after the main network goes online, the future UYT ecological projects will compete to bid for slots. In fact, the original intention of UYT is to realize the interconnection of all chains. The chain outside the UYT ecology also needs to communicate. The third is cross-fi. The BIFI is hatched on Ethereum, and the def on UYT can realize multi-chain operation. For example, TkN games or future UTC game platform users can call bitcoin on the UYT chain. This form only belongs to the decentralized finance in the cross-chain era of UYT, which can be called cross-fi. Q11. Which exchanges will UYT go online next? What is the online strategy like? Answer: As the founder of ignisvc and as UYT As the head of the Dao organization, we have always had good cooperative relations with major exchanges all over the world. TKNT will appear in several exchanges one after another. Hitbtc exchange in the United Kingdom, Upbit and Bithumb Exchange in South Korea, Bitfinex exchange in the United States, Binance exchange in China, BKEX exchange, and Kucoin exchange in China are all our partners, and they have been paying close attention to UYT Development, UYT is the public chain with the largest user base and the highest community participation in the cross-chain field, so the future value is immeasurable. If we have to go to the exchange, then we will choose one of the above exchanges to launch. But the vision of UYT is to create a fairer, safer, and transparent circulation in the field of digital currency, and users can master all the assets by themselves, Therefore, in the beginning, there is a simple DEX on the UYT wallet, which is a simple matchmaking transaction and is also an on-chain transaction. After the completion of the UYT DEX, more transactions may occur in the UYT DEX. However, after the main network of UYT is online, centralized exchanges can directly access the block data synchronization of UYT, and it is not ruled out that some exchanges will directly go online for UYT trading. Such exchanges will not enjoy the support of the ecological support fund of UYT. The network project is a community-led project. Each cooperation plan of the exchange will be carried out in the way shared by the community in the future. Dao organization can only implement it according to the voting results. Q12. What are the plans for the promotion of ecological development and market by the launch of UYT main network? Answer: The launch of the main network will be completed around October 15. On the offline side, due to the epidemic situation, we will jointly organize corresponding market activities with nodes in different countries. At present, there are three large-scale offline meetups that have been identified. We will also start a global roadshow when the epidemic is over. On the online side, we have opened online Wechat, Kakao, Twitter, Reddit, and telegram communities. We will carry out AMA activities in various countries and promote them all over the world in various ways. Of course, we will launch MLM plans and cooperate with more marketing teams.

It can be transferred through the network with zero-fees, reflecting the best features of today's cash. What is Private DeFi? Privacy should be fundamental in financial transactions. However, many existing DeFi platforms, such as Ethereum for example, fail to fulfil this criterion – either partly or completely. The Autobahn Network is one of the first of its kind to truly support private DeFi. What is DeFi about the Autobahn Network? The Autobahn Network will initially focus on the areas of asset tokenisation and providing a second-layer platform for existing assets on other chains. This will provide the foundation for offering further DeFi use cases in the future. The current focus is on the launch of Alphanet, which will be the first production release of the Autobahn Network. The Autobahn Network is a decentralized next-generation, second-layer solution for digital assets. It provides the ability to use any cryptocurrency, including Bitcoin, as an efficient & effective means of world payment. The Autobahn Network employs the most sophisticated technologies to have emerged from the blockchain world over recent years to build a decentralized network, tailored for payments. Bitcoin, and other digital assets, can be sent to the Autobahn Network. Once they are in the network they can then be transferred quickly, privately and with low transaction fees. HOW DOES IT WORK? • Send BTC to the Autobahn Network Gateway • The decentralized nodes hold your BTC via a Threshold Signature Scheme (TSS) • Transfer BTC within the network as often as you like • Withdraw BTC to the main blockchain, if you plan to hold it there • The decentralized nodes release your BTC via TSS To fully appreciate high-speed, you have to experience it yourself. They have developed a fully working Testnet especially for this purpose: https://autobahn.network/testnet The Autobahn Network is developed by the non-profit company - Tixl gGmbH, based in Hamburg (Germany). Tixl raised seed capital of USD $1,250,000 in early 2019 by selling the Tixl Token (MTXLT) to retail investors. Tech behind the Autobahn https://medium.com/tixlcurrency/the-technology-behind-the-autobahn-network-81fdecf41c20 Most of the time the bottleneck is the consensus. Tixl use their own implementation of the Stellar Consensus Protocol (SCP). Since SCP is known to establish consensus within a few seconds, even if there are some more conflicting transactions, nodes will still be able to reach consensus quickly. It’s also known that SCP can deal with high transaction volumes. Although there is no verified statement from the Stellar foundation, there are rumors that SCP can handle 10,000 transactions per second in certain network constellations Project milestones and key links

Find more details on these events in the medium article released today https://link.medium.com/qXfp3zjM57 WHY TIXL? A number of different concepts for improving Bitcoin and the transfer of digital assets in general have been developed, with the ultimate goal of achieving fast and cheap transactions, or to provide privacy. The Tixl Token on the Autobahn Network provides a perfect combination of them all. REVENUE STREAMS Transaction Fees Transactions in the Autobahn Network will be cheap but not completely free. Fees will be paid using in the currency of the asset being transfered. The revenue will then be used to purchase MTXLT on the open market. As a result, fees are indirectly paid in MTXLT. Listing Fees As soon as the Autobahn Network gains adoption, it will become a sought-after platform for other assets. A (monthly) listing fee, to be paid in MTXLT, will also serve to increase the public demand for MTXLT. Additional Services Besides the obvious sources of revenue, other features - like the purchase of nicknames - can also be used to generate revenue. Social media buzz Ivan on Tech about Tixl in "TOP ALTCOINS 2020 - Programmer explains" https://youtu.be/ynyvwZetb8s Something different? Tixl global reserve has been developed to provide extra confidence to investors. Read more here: https://medium.com/tixlcurrency/tixl-global-reserve-tgr-update-c59bee09c66d Other questions Do I need TXL to send and receive BTC and other third-party assets? To ensure the greatest usability, they decided against using TXL directly as "fuel" because it would provide an obstacle to use if you had to buy TXL before you are able to transfer BTC, or other digital assets. The same issue has attracted criticism from users of other networks that support different assets. As a solution, they settled on the idea of allowing transaction fees for certain assets (for example, BTC) to be paid in their native currency. One can send BTC through the Autobahn Network without having to purchase TXL and pay much lower fees than you would on the Bitcoin blockchain itself. How is Autobahn Network secured by Bitcoin? To increase the decentralization of Autobahn Network, a hash representing the current state of the Autobahn Network ledger will be written onto the Bitcoin blockchain regularly. In doing so, the Autobahn Network will increase its trust level by leveraging the most secure and immutable blockchain in the world.
How To End The Cryptocurrency Exchange "Wild West" Without Crippling Innovation
In case you haven't noticed the consultation paper, staff notice, and report on Quadriga, regulators are now clamping down on Canadian cryptocurrency exchanges. The OSC and other regulatory bodies are still interested in industry feedback. They have not put forward any official regulation yet. Below are some ideas/insights and a proposed framework.
Typical securities frameworks will cost Canadians millions of dollars (ie Sarbanes-Oxley estimated at $5m USD/yr per firm). Implementation costs of this proposal are significantly cheaper.
Canadians can maintain a diverse set of exchanges, multiple viable business models are still fully supported, and innovation is encouraged while keeping Canadians safe.
Many of you have limited time to read the full proposal, so here are the highlights:
Effective standards to prevent both internal and external theft. Exchange operators are trained and certified, and have a legal responsibility to users.
Regular Transparent Audits
Provides visibility to Canadians that their funds are fully backed on the exchange, while protecting privacy and sensitive platform information.
Establishment of basic insurance standards/strategy, to expand over time. Removing risk to exchange users of any hot wallet theft.
Background and Justifications
Cold Storage Custody/Management After reviewing close to 100 cases, all thefts tend to break down into more or less the same set of problems: • Funds stored online or in a smart contract, • Access controlled by one person or one system, • 51% attacks (rare), • Funds sent to the wrong address (also rare), or • Some combination of the above. For the first two cases, practical solutions exist and are widely implemented on exchanges already. Offline multi-signature solutions are already industry standard. No cases studied found an external theft or exit scam involving an offline multi-signature wallet implementation. Security can be further improved through minimum numbers of signatories, background checks, providing autonomy and legal protections to each signatory, establishing best practices, and a training/certification program. The last two transaction risks occur more rarely, and have never resulted in a loss affecting the actual users of the exchange. In all cases to date where operators made the mistake, they've been fully covered by the exchange platforms. • 51% attacks generally only occur on blockchains with less security. The most prominent cases have been Bitcoin Gold and Ethereum Classic. The simple solution is to enforce deposit limits and block delays such that a 51% attack is not cost-effective. • The risk of transactions to incorrect addresses can be eliminated by a simple test transaction policy on large transactions. By sending a small amount of funds prior to any large withdrawals/transfers as a standard practice, the accuracy of the wallet address can be validated. The proposal covers all loss cases and goes beyond, while avoiding significant additional costs, risks, and limitations which may be associated with other frameworks like SOC II. On The Subject of Third Party Custodians Many Canadian platforms are currently experimenting with third party custody. From the standpoint of the exchange operator, they can liberate themselves from some responsibility of custody, passing that off to someone else. For regulators, it puts crypto in similar categorization to oil, gold, and other commodities, with some common standards. Platform users would likely feel greater confidence if the custodian was a brand they recognized. If the custodian was knowledgeable and had a decent team that employed multi-sig, they could keep assets safe from internal theft. With the right protections in place, this could be a great solution for many exchanges, particularly those that lack the relevant experience or human resources for their own custody systems. However, this system is vulnerable to anyone able to impersonate the exchange operators. You may have a situation where different employees who don't know each other that well are interacting between different companies (both the custodian and all their customers which presumably isn't just one exchange). A case study of what can go wrong in this type of environment might be Bitpay, where the CEO was tricked out of 5000 bitcoins over 3 separate payments by a series of emails sent legitimately from a breached computer of another company CEO. It's also still vulnerable to the platform being compromised, as in the really large $70M Bitfinex hack, where the third party Bitgo held one key in a multi-sig wallet. The hacker simply authorized the withdrawal using the same credentials as Bitfinex (requesting Bitgo to sign multiple withdrawal transactions). This succeeded even with the use of multi-sig and two heavily security-focused companies, due to the lack of human oversight (basically, hot wallet). Of course, you can learn from these cases and improve the security, but so can hackers improve their deception and at the end of the day, both of these would have been stopped by the much simpler solution of a qualified team who knew each other and employed multi-sig with properly protected keys. It's pretty hard to beat a human being who knows the business and the typical customer behaviour (or even knows their customers personally) at spotting fraud, and the proposed multi-sig means any hacker has to get through the scrutiny of 3 (or more) separate people, all of whom would have proper training including historical case studies. There are strong arguments both for and against using use of third party custodians. The proposal sets mandatory minimum custody standards would apply regardless if the cold wallet signatories are exchange operators, independent custodians, or a mix of both. On The Subject Of Insurance ShakePay has taken the first steps into this new realm (congratulations). There is no question that crypto users could be better protected by the right insurance policies, and it certainly feels better to transact with insured platforms. The steps required to obtain insurance generally place attention in valuable security areas, and in this case included a review from CipherTrace. One of the key solutions in traditional finance comes from insurance from entities such as the CDIC. However, historically, there wasn't found any actual insurance payout to any cryptocurrency exchange, and there are notable cases where insurance has not paid. With Bitpay, for example, the insurance agent refused because the issue happened to the third party CEO's computer instead of anything to do with Bitpay itself. With the Youbit exchange in South Korea, their insurance claim was denied, and the exchange ultimately ended up instead going bankrupt with all user's funds lost. To quote Matt Johnson in the original Lloyd's article: “You can create an insurance policy that protects no one – you know there are so many caveats to the policy that it’s not super protective.” ShakePay's insurance was only reported to cover their cold storage, and “physical theft of the media where the private keys are held”. Physical theft has never, in the history of cryptocurrency exchange cases reviewed, been reported as the cause of loss. From the limited information of the article, ShakePay made it clear their funds are in the hands of a single US custodian, and at least part of their security strategy is to "decline to confirm the custodian’s name on the record". While this prevents scrutiny of the custodian, it's pretty silly to speculate that a reasonably competent hacking group couldn't determine who the custodian is. A far more common infiltration strategy historically would be social engineering, which has succeeded repeatedly. A hacker could trick their way into ShakePay's systems and request a fraudulent withdrawal, impersonate ShakePay and request the custodian to move funds, or socially engineer their way into the custodian to initiate the withdrawal of multiple accounts (a payout much larger than ShakePay) exploiting the standard procedures (for example, fraudulently initiating or override the wallet addresses of a real transfer). In each case, nothing was physically stolen and the loss is therefore not covered by insurance. In order for any insurance to be effective, clear policies have to be established about what needs to be covered. Anything short of that gives Canadians false confidence that they are protected when they aren't in any meaningful way. At this time, the third party insurance market does not appear to provide adequate options or coverage, and effort is necessary to standardize custody standards, which is a likely first step in ultimately setting up an insurance framework. A better solution compared to third party insurance providers might be for Canadian exchange operators to create their own collective insurance fund, or a specific federal organization similar to the CDIC. Such an organization would have a greater interest or obligation in paying out actual cases, and that would be it's purpose rather than maximizing it's own profit. This would be similar to the SAFU which Binance has launched, except it would cover multiple exchanges. There is little question whether the SAFU would pay out given a breach of Binance, and a similar argument could be made for a insurance fund managed by a collective of exchange operators or a government organization. While a third party insurance provider has the strong market incentive to provide the absolute minimum coverage and no market incentive to payout, an entity managed by exchange operators would have incentive to protect the reputation of exchange operators/the industry, and the government should have the interest of protecting Canadians. On The Subject of Fractional Reserve There is a long history of fractional reserve failures, from the first banks in ancient times, through the great depression (where hundreds of fractional reserve banks failed), right through to the 2008 banking collapse referenced in the first bitcoin block. The fractional reserve system allows banks to multiply the money supply far beyond the actual cash (or other assets) in existence, backed only by a system of debt obligations of others. Safely supporting a fractional reserve system is a topic of far greater complexity than can be addressed by a simple policy, and when it comes to cryptocurrency, there is presently no entity reasonably able to bail anyone out in the event of failure. Therefore, this framework is addressed around entities that aim to maintain 100% backing of funds. There may be some firms that desire but have failed to maintain 100% backing. In this case, there are multiple solutions, including outside investment, merging with other exchanges, or enforcing a gradual restoration plan. All of these solutions are typically far better than shutting down the exchange, and there are multiple cases where they've been used successfully in the past. Proof of Reserves/Transparency/Accountability Canadians need to have visibility into the backing on an ongoing basis. The best solution for crypto-assets is a Proof of Reserve. Such ideas go back all the way to 2013, before even Mt. Gox. However, no Canadian exchange has yet implemented such a system, and only a few international exchanges (CoinFloor in the UK being an example) have. Many firms like Kraken, BitBuy, and now ShakePay use the Proof of Reserve term to refer to lesser proofs which do not actually cryptographically prove the full backing of all user assets on the blockchain. In order for a Proof of Reserve to be effective, it must actually be a complete proof, and it needs to be understood by the public that is expected to use it. Many firms have expressed reservations about the level of transparency required in a complete Proof of Reserve (for example Kraken here). While a complete Proof of Reserves should be encouraged, and there are some solutions in the works (ie TxQuick), this is unlikely to be suitable universally for all exchange operators and users. Given the limitations, and that firms also manage fiat assets, a more traditional audit process makes more sense. Some Canadian exchanges (CoinSquare, CoinBerry) have already subjected themselves to annual audits. However, these results are not presently shared publicly, and there is no guarantee over the process including all user assets or the integrity and independence of the auditor. The auditor has been typically not known, and in some cases, the identity of the auditor is protected by a NDA. Only in one case (BitBuy) was an actual report generated and publicly shared. There has been no attempt made to validate that user accounts provided during these audits have been complete or accurate. A fraudulent fractional exchange, or one which had suffered a breach they were unwilling to publicly accept (see CoinBene), could easily maintain a second set of books for auditors or simply exclude key accounts to pass an individual audit. The proposed solution would see a reporting standard which includes at a minimum - percentage of backing for each asset relative to account balances and the nature of how those assets are stored, with ownership proven by the auditor. The auditor would also publicly provide a "hash list", which they independently generate from the accounts provided by the exchange. Every exchange user can then check their information against this public "hash list". A hash is a one-way form of encryption, which fully protects the private information, yet allows anyone who knows that information already to validate that it was included. Less experienced users can take advantage of public tools to calculate the hash from their information (provided by the exchange), and thus have certainty that the auditor received their full balance information. Easy instructions can be provided. Auditors should be impartial, their identities and process public, and they should be rotated so that the same auditor is never used twice in a row. Balancing the cost of auditing against the needs for regular updates, a 6 month cycle likely makes the most sense. Hot Wallet Management The best solution for hot wallets is not to use them. CoinBerry reportedly uses multi-sig on all withdrawals, and Bitmex is an international example known for their structure devoid of hot wallets. However, many platforms and customers desire fast withdrawal processes, and human validation has a cost of time and delay in this process. A model of self-insurance or separate funds for hot wallets may be used in these cases. Under this model, a platform still has 100% of their client balance in cold storage and holds additional funds in hot wallets for quick withdrawal. Thus, the risk of those hot wallets is 100% on exchange operators and not affecting the exchange users. Since most platforms typically only have 1%-5% in hot wallets at any given time, it shouldn't be unreasonable to build/maintain these additional reserves over time using exchange fees or additional investment. Larger withdrawals would still be handled at regular intervals from the cold storage. Hot wallet risks have historically posed a large risk and there is no established standard to guarantee secure hot wallets. When the government of South Korea dispatched security inspections to multiple exchanges, the results were still that 3 of them got hacked after the inspections. If standards develop such that an organization in the market is willing to insure the hot wallets, this could provide an acceptable alternative. Another option may be for multiple exchange operators to pool funds aside for a hot wallet insurance fund. Comprehensive coverage standards must be established and maintained for all hot wallet balances to make sure Canadians are adequately protected.
Current Draft Proposal
(1) Proper multi-signature cold wallet storage. (a) Each private key is the personal and legal responsibility of one person - the “signatory”. Signatories have special rights and responsibilities to protect user assets. Signatories are trained and certified through a course covering (1) past hacking and fraud cases, (2) proper and secure key generation, and (3) proper safekeeping of private keys. All private keys must be generated and stored 100% offline by the signatory. If even one private keys is ever breached or suspected to be breached, the wallet must be regenerated and all funds relocated to a new wallet. (b) All signatories must be separate background-checked individuals free of past criminal conviction. Canadians should have a right to know who holds their funds. All signing of transactions must take place with all signatories on Canadian soil or on the soil of a country with a solid legal system which agrees to uphold and support these rules (from an established white-list of countries which expands over time). (c) 3-5 independent signatures are required for any withdrawal. There must be 1-3 spare signatories, and a maximum of 7 total signatories. The following are all valid combinations: 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7. (d) A security audit should be conducted to validate the cold wallet is set up correctly and provide any additional pertinent information. The primary purpose is to ensure that all signatories are acting independently and using best practices for private key storage. A report summarizing all steps taken and who did the audit will be made public. Canadians must be able to validate the right measures are in place to protect their funds. (e) There is a simple approval process if signatories wish to visit any country outside Canada, with a potential whitelist of exempt countries. At most 2 signatories can be outside of aligned jurisdiction at any given time. All exchanges would be required to keep a compliant cold wallet for Canadian funds and have a Canadian office if they wish to serve Canadian customers. (2) Regular and transparent solvency audits. (a) An audit must be conducted at founding, after 3 months of operation, and at least once every 6 months to compare customer balances against all stored cryptocurrency and fiat balances. The auditor must be known, independent, and never the same twice in a row. (b) An audit report will be published featuring the steps conducted in a readable format. This should be made available to all Canadians on the exchange website and on a government website. The report must include what percentage of each customer asset is backed on the exchange, and how those funds are stored. (c) The auditor will independently produce a hash of each customer's identifying information and balance as they perform the audit. This will be made publicly available on the exchange and government website, along with simplified instructions that each customer can use to verify that their balance was included in the audit process. (d) The audit needs to include a proof of ownership for any cryptocurrency wallets included. A satoshi test (spending a small amount) or partially signed transaction both qualify. (e) Any platform without 100% reserves should be assessed on a regular basis by a government or industry watchdog. This entity should work to prevent any further drop, support any private investor to come in, or facilitate a merger so that 100% backing can be obtained as soon as possible. (3) Protections for hot wallets and transactions. (a) A standardized list of approved coins and procedures will be established to constitute valid cold storage wallets. Where a multi-sig process is not natively available, efforts will be undertaken to establish a suitable and stable smart contract standard. This list will be expanded and improved over time. Coins and procedures not on the list are considered hot wallets. (b) Hot wallets can be backed by additional funds in cold storage or an acceptable third-party insurance provider with a comprehensive coverage policy. (c) Exchanges are required to cover the full balance of all user funds as denominated in the same currency, or double the balance as denominated in bitcoin or CAD using an established trading rate. If the balance is ever insufficient due to market movements, the firm must rectify this within 24 hours by moving assets to cold storage or increasing insurance coverage. (d) Any large transactions (above a set threshold) from cold storage to any new wallet addresses (not previously transacted with) must be tested with a smaller transaction first. Deposits of cryptocurrency must be limited to prevent economic 51% attacks. Any issues are to be covered by the exchange. (e) Exchange platforms must provide suitable authentication for users, including making available approved forms of two-factor authentication. SMS-based authentication is not to be supported. Withdrawals must be blocked for 48 hours in the event of any account password change. Disputes on the negligence of exchanges should be governed by case law.
Continued review of existing OSC feedback is still underway. More feedback and opinions on the framework and ideas as presented here are extremely valuable. The above is a draft and not finalized. The process of further developing and bringing a suitable framework to protect Canadians will require the support of exchange operators, legal experts, and many others in the community. The costs of not doing such are tremendous. A large and convoluted framework, one based on flawed ideas or implementation, or one which fails to properly safeguard Canadians is not just extremely expensive and risky for all Canadians, severely limiting to the credibility and reputation of the industry, but an existential risk to many exchanges. The responsibility falls to all of us to provide our insight and make our opinions heard on this critical matter. Please take the time to give your thoughts.
In this research report, we present a study on Kyber Network. Kyber Network is a decentralized, on-chain liquidity protocol designed to make trading tokens simple, efficient, robust and secure. Kyber design allows any party to contribute to an aggregated pool of liquidity within each blockchain while providing a single endpoint for takers to execute trades using the best rates available. We envision a connected liquidity network that facilitates seamless, decentralized cross-chain token swaps across Kyber based networks on different chains. Kyber is a fully on-chain liquidity protocol that enables decentralized exchange of cryptocurrencies in any application. Liquidity providers (Reserves) are integrated into one single endpoint for takers and users. When a user requests a trade, the protocol will scan the entire network to find the reserve with the best price and take liquidity from that particular reserve.
DeFi applications all need access to good liquidity sources, which is a critical component to provide good services. Currently, decentralized liquidity is comprised of various sources including DEXes (Uniswap, OasisDEX, Bancor), decentralized funds and other financial apps. The more scattered the sources, the harder it becomes for anyone to either find the best rate for their trade or to even find enough liquidity for their need. Kyber is a blockchain-based liquidity protocol that aggregates liquidity from a wide range of reserves, powering instant and secure token exchange in any decentralized application. The protocol allows for a wide range of implementation possibilities for liquidity providers, allowing a wide range of entities to contribute liquidity, including end users, decentralized exchanges and other decentralized protocols. On the taker side, end users, cryptocurrency wallets, and smart contracts are able to perform instant and trustless token trades at the best rates available amongst the sources. The Kyber Network is project based on the Ethereum protocol that seeks to completely decentralize the exchange of crypto currencies and make exchange trustless by keeping everything on the blockchain. Through the Kyber Network, users should be able to instantly convert or exchange any crypto currency.
1.1 OVERVIEW ABOUT KYBER NETWORK PROTOCOL
The Kyber Network is a decentralized way to exchange ETH and different ERC20 tokens instantly — no waiting and no registration needed. Using this protocol, developers can build innovative payment flows and applications, including instant token swap services, ERC20 payments, and financial DApps — helping to build a world where any token is usable anywhere. Kyber’s fully on-chain design allows for full transparency and verifiability in the matching engine, as well as seamless composability with DApps, not all of which are possible with off-chain or hybrid approaches. The integration of a large variety of liquidity providers also makes Kyber uniquely capable of supporting sophisticated schemes and catering to the needs of DeFi DApps and financial institutions. Hence, many developers leverage Kyber’s liquidity pool to build innovative financial applications, and not surprisingly, Kyber is the most used DeFi protocol in the world. The Kyber Network is quite an established project that is trying to change the way we think of decentralised crypto currency exchange. The Kyber Network has seen very rapid development. After being announced in May 2017 the testnet for the Kyber Network went live in August 2017. An ICO followed in September 2017, with the company raising 200,000 ETH valued at $60 million in just one day. The live main net was released in February 2018 to whitelisted participants, and on March 19, 2018, the Kyber Network opened the main net as a public beta. Since then the network has seen increasing growth, with network volumes growing more than 500% in the first half of 2019. Although there was a modest decrease in August 2019 that can be attributed to the price of ETH dropping by 50%, impacting the overall total volumes being traded and processed globally. They are developing a decentralised exchange protocol that will allow developers to build payment flows and financial apps. This is indeed quite a competitive market as a number of other such protocols have been launched. In Brief - Kyber Network is a tool that allows anyone to swap tokens instantly without having to use exchanges. - It allows vendors to accept different types of cryptocurrency while still being paid in their preferred crypto of choice. - It’s built primarily for Ethereum, but any smart-contract based blockchain can incorporate it. At its core, Kyber is a decentralized way to exchange ETH and different ERC20 tokens instantly–no waiting and no registration needed. To do this Kyber uses a diverse set of liquidity pools, or pools of different crypto assets called “reserves” that any project can tap into or integrate with. A typical use case would be if a vendor allowed customers to pay in whatever currency they wish, but receive the payment in their preferred token. Another example would be for Dapp users. At present, if you are not a token holder of a certain Dapp you can’t use it. With Kyber, you could use your existing tokens, instantly swap them for the Dapp specific token and away you go. All this swapping happens directly on the Ethereum blockchain, meaning every transaction is completely transparent.
1.1.1 WHY BUILD THE KYBER NETWORK?
While crypto currencies were built to be decentralized, many of the exchanges for trading crypto currencies have become centralized affairs. This has led to security vulnerabilities, with many exchanges becoming the victims of hacking and theft. It has also led to increased fees and costs, and the centralized exchanges often come with slow transfer times as well. In some cases, wallets have been locked and users are unable to withdraw their coins. Decentralized exchanges have popped up recently to address the flaws in the centralized exchanges, but they have their own flaws, most notably a lack of liquidity, and often times high costs to modify trades in their on-chain order books. Some of the Integrations with Kyber Protocol The Kyber Network was formed to provide users with a decentralized exchange that keeps everything right on the blockchain, and uses a reserve system rather than an order book to provide high liquidity at all times. This will allow for the exchange and transfer of any cryptocurrency, even cross exchanges, and costs will be kept at a minimum as well. The Kyber Network has three guiding design philosophies since the start:
To be most useful the network needs to be platform-agnostic, which allows any protocol or application the ability to take advantage of the liquidity provided by the Kyber Network without any impact on innovation.
The network was designed to make real-world commerce and decentralized financial products not only possible but also feasible. It does this by allowing for instant token exchange across a wide range of tokens, and without any settlement risk.
The Kyber Network was created with ease of integration as a priority, which is why everything runs fully on-chain and fully transparent. Kyber is not only developer-friendly, but is also compatible with a wide variety of systems.
1.1.2 WHO INVENTED KYBER?
Kyber’s founders are Loi Luu, Victor Tran, Yaron Velner — CEO, CTO, and advisor to the Kyber Network.
1.1.3 WHAT DISTINGUISHES KYBER?
Kyber’s mission has always been to integrate with other protocols so they’ve focused on being developer-friendly by providing architecture to allow anyone to incorporate the technology onto any smart-contract powered blockchain. As a result, a variety of different dapps, vendors, and wallets use Kyber’s infrastructure including Set Protocol, bZx, InstaDApp, and Coinbase wallet. Besides, dapps, vendors, and wallets, Kyber also integrates with other exchanges such as Uniswap — sharing liquidity pools between the two protocols. A typical use case would be if a vendor allowed customers to pay in whatever currency they wish, but receive the payment in their preferred token. Another example would be for Dapp users. At present, if you are not a token holder of a certain Dapp you can’t use it. With Kyber, you could use your existing tokens, instantly swap them for the Dapp specific token and away you go. Limit orders on Kyber allow users to set a specific price in which they would like to exchange a token instead of accepting whatever price currently exists at the time of trading. However, unlike with other exchanges, users never lose custody of their crypto assets during limit orders on Kyber. The Kyber protocol works by using pools of crypto funds called “reserves”, which currently support over 70 different ERC20 tokens. Reserves are essentially smart contracts with a pool of funds. Different parties with different prices and levels of funding control all reserves. Instead of using order books to match buyers and sellers to return the best price, the Kyber protocol looks at all the reserves and returns the best price among the different reserves. Reserves make money on the “spread” or differences between the buying and selling prices. The Kyber wants any token holder to easily convert one token to another with a minimum of fuss.
1.2 KYBER PROTOCOL
The protocol smart contracts offer a single interface for the best available token exchange rates to be taken from an aggregated liquidity pool across diverse sources. ● Aggregated liquidity pool. The protocol aggregates various liquidity sources into one liquidity pool, making it easy for takers to find the best rates offered with one function call. ● Diverse sources of liquidity. The protocol allows different types of liquidity sources to be plugged into. Liquidity providers may employ different strategies and different implementations to contribute liquidity to the protocol. ● Permissionless. The protocol is designed to be permissionless where any developer can set up various types of reserves, and any end user can contribute liquidity. Implementations need to take into consideration various security vectors, such as reserve spamming, but can be mitigated through a staking mechanism. We can expect implementations to be permissioned initially until the maintainers are confident about these considerations. The core feature that the Kyber protocol facilitates is the token swap between taker and liquidity sources. The protocol aims to provide the following properties for token trades: ● Instant Settlement. Takers do not have to wait for their orders to be fulfilled, since trade matching and settlement occurs in a single blockchain transaction. This enables trades to be part of a series of actions happening in a single smart contract function. ● Atomicity. When takers make a trade request, their trade either gets fully executed, or is reverted. This “all or nothing” aspect means that takers are not exposed to the risk of partial trade execution. ● Public rate verification. Anyone can verify the rates that are being offered by reserves and have their trades instantly settled just by querying from the smart contracts. ● Ease of integration. Trustless and atomic token trades can be directly and easily integrated into other smart contracts, thereby enabling multiple trades to be performed in a smart contract function. How each actor works is specified in Section Network Actors. 1. Takers refer to anyone who can directly call the smart contract functions to trade tokens, such as end-users, DApps, and wallets. 2. Reserves refer to anyone who wishes to provide liquidity. They have to implement the smart contract functions defined in the reserve interface in order to be registered and have their token pairs listed. 3. Registered reserves refer to those that will be cycled through for matching taker requests. 4. Maintainers refer to anyone who has permission to access the functions for the adding/removing of reserves and token pairs, such as a DAO or the team behind the protocol implementation. 5. In all, they comprise of the network, which refers to all the actors involved in any given implementation of the protocol. The protocol implementation needs to have the following: 1. Functions for takers to check rates and execute the trades 2. Functions for the maintainers to registeremove reserves and token pairs 3. Reserve interface that defines the functions reserves needs to implement https://preview.redd.it/d2tcxc7wdcg51.png?width=700&format=png&auto=webp&s=b2afde388a77054e6731772b9115ee53f09b6a4a
1.3 KYBER CORE SMART CONTRACTS
Kyber Core smart contracts is an implementation of the protocol that has major protocol functions to allow actors to join and interact with the network. For example, the Kyber Core smart contracts provide functions for the listing and delisting of reserves and trading pairs by having clear interfaces for the reserves to comply to be able to register to the network and adding support for new trading pairs. In addition, the Kyber Core smart contracts also provide a function for takers to query the best rate among all the registered reserves, and perform the trades with the corresponding rate and reserve. A trading pair consists of a quote token and any other token that the reserve wishes to support. The quote token is the token that is either traded from or to for all trades. For example, the Ethereum implementation of the Kyber protocol uses Ether as the quote token. In order to search for the best rate, all reserves supporting the requested token pair will be iterated through. Hence, the Kyber Core smart contracts need to have this search algorithm implemented. The key functions implemented in the Kyber Core Smart Contracts are listed in Figure 2 below. We will visit and explain the implementation details and security considerations of each function in the Specification Section.
1.4 HOW KYBER’S ON-CHAIN PROTOCOL WORKS?
Kyber is the liquidity infrastructure for decentralized finance. Kyber aggregates liquidity from diverse sources into a pool, which provides the best rates for takers such as DApps, Wallets, DEXs, and End users.
1.4.1 PROVIDING LIQUIDITY AS A RESERVE
Anyone can operate a Kyber Reserve to market make for profit and make their tokens available for DApps in the ecosystem. Through an open reserve architecture, individuals, token teams and professional market makers can contribute token assets to Kyber’s liquidity pool and earn from the spread in every trade. These tokens become available at the best rates across DApps that tap into the network, making them instantly more liquid and useful. MAIN RESERVE TYPES Kyber currently has over 45 reserves in its network providing liquidity. There are 3 main types of reserves that allow different liquidity contribution options to suit the unique needs of different providers. 1. Automated Price Reserves (APR) — Allows token teams and users with large token holdings to have an automated yet customized pricing system with low maintenance costs. Synthetix and Melon are examples of teams that run APRs. 2. Fed Price Reserves (FPR) — Operated by professional market makers that require custom and advanced pricing strategies tailored to their specific needs. Kyber alongside reserves such as OneBit, runs FPRs. 3. Bridge Reserves (BR) — These are specialized reserves meant to bring liquidity from other on-chain liquidity providers like Uniswap, Oasis, DutchX, and Bancor into the network.
1.5 KYBER NETWORK ROLES
There Kyber Network functions through coordination between several different roles and functions as explained below: - Users — This entity uses the Kyber Network to send and receive tokens. A user can be an individual, a merchant, and even a smart contract account. - Reserve Entities — This role is used to add liquidity to the platform through the dynamic reserve pool. Some reserve entities are internal to the Kyber Network, but others may be registered third parties. Reserve entities may be public if the public contributes to the reserves they hold, otherwise they are considered private. By allowing third parties as reserve entities the network adds diversity, which prevents monopolization and keeps exchange rates competitive. Allowing third party reserve entities also allows for the listing of less popular coins with lower volumes. - Reserve Contributors — Where reserve entities are classified as public, the reserve contributor is the entity providing reserve funds. Their incentive for doing so is a profit share from the reserve. - The Reserve Manager — Maintains the reserve, calculates exchange rates and enters them into the network. The reserve manager profits from exchange spreads set by them on their reserves. They can also benefit from increasing volume by accessing the entire Kyber Network. - The Kyber Network Operator — Currently the Kyber Network team is filling the role of the network operator, which has a function to adds/remove Reserve Entities as well as controlling the listing of tokens. Eventually, this role will revert to a proper decentralized governance.
1.6 BASIC TOKEN TRADE
A basic token trade is one that has the quote token as either the source or destination token of the trade request. The execution flow of a basic token trade is depicted in the diagram below, where a taker would like to exchange BAT tokens for ETH as an example. The trade happens in a single blockchain transaction. 1. Taker sends 1 ETH to the protocol contract, and would like to receive BAT in return. 2. Protocol contract queries the first reserve for its ETH to BAT exchange rate. 3. Reserve 1 offers an exchange rate of 1 ETH for 800 BAT. 4. Protocol contract queries the second reserve for its ETH to BAT exchange rate. 5. Reserve 2 offers an exchange rate of 1 ETH for 820 BAT. 6. This process goes on for the other reserves. After the iteration, reserve 2 is discovered to have offered the best ETH to BAT exchange rate. 7. Protocol contract sends 1 ETH to reserve 2. 8. The reserve sends 820 BAT to the taker.
1.7 TOKEN-TO-TOKEN TRADE
A token-to-token trade is one where the quote token is neither the source nor the destination token of the trade request. The exchange flow of a token to token trade is depicted in the diagram below, where a taker would like to exchange BAT tokens for DAI as an example. The trade happens in a single blockchain transaction. 1. Taker sends 50 BAT to the protocol contract, and would like to receive DAI in return. 2. Protocol contract sends 50 BAT to the reserve offering the best BAT to ETH rate. 3. Protocol contract receives 1 ETH in return. 4. Protocol contract sends 1 ETH to the reserve offering the best ETH to DAI rate. 5. Protocol contract receives 30 DAI in return. 6. Protocol contract sends 30 DAI to the user.
2.KYBER NETWORK CRYSTAL (KNC) TOKEN
Kyber Network Crystal (KNC) is an ERC-20 utility token and an integral part of Kyber Network. KNC is the first deflationary staking token where staking rewards and token burns are generated from actual network usage and growth in DeFi. The Kyber Network Crystal (KNC) is the backbone of the Kyber Network. It works to connect liquidity providers and those who need liquidity and serves three distinct purposes. The first of these is to collect transaction fees, and a portion of every fee collected is burned, which keeps KNC deflationary. Kyber Network Crystals (KNC), are named after the crystals in Star Wars used to power light sabers. The KNC also ensures the smooth operation of the reserve system in the Kyber liquidity since entities must use third-party tokens to buy the KNC that pays for their operations in the network. KNC allows token holders to play a critical role in determining the incentive system, building a wide base of stakeholders, and facilitating economic flow in the network. A small fee is charged each time a token exchange happens on the network, and KNC holders get to vote on this fee model and distribution, as well as other important decisions. Over time, as more trades are executed, additional fees will be generated for staking rewards and reserve rebates, while more KNC will be burned. - Participation rewards — KNC holders can stake KNC in the KyberDAO and vote on key parameters. Voters will earn staking rewards (in ETH) - Burning — Some of the network fees will be burned to reduce KNC supply permanently, providing long-term value accrual from decreasing supply. - Reserve incentives — KNC holders determine the portion of network fees that are used as rebates for selected liquidity providers (reserves) based on their volume performance. Finally, the KNC token is the connection between the Kyber Network and the exchanges, wallets, and dApps that leverage the liquidity network. This is a virtuous system since entities are rewarded with referral fees for directing more users to the Kyber Network, which helps increase adoption for Kyber and for the entities using the Network. And of course there will soon be a fourth and fifth uses for the KNC, which will be as a staking token used to generate passive income, as well as a governance token used to vote on key parameters of the network. The Kyber Network Crystal (KNC) was released in a September 2017 ICO at a price around $1. There were 226,000,000 KNC minted for the ICO, with 61% sold to the public. The remaining 39% are controlled 50/50 by the company and the founders/advisors, with a 1 year lockup period and 2 year vesting period. Currently, just over 180 million coins are in circulation, and the total supply has been reduced to 210.94 million after the company burned 1 millionth KNC token in May 2019 and then its second millionth KNC token just three months later. That means that while it took 15 months to burn the first million KNC, it took just 10 weeks to burn the second million KNC. That shows how rapidly adoption has been growing recently for Kyber, with July 2019 USD trading volumes on the Kyber Network nearly reaching $60 million. This volume has continued growing, and on march 13, 2020 the network experienced its highest daily trading activity of $33.7 million in a 24-hour period. Currently KNC is required by Reserve Managers to operate on the network, which ensures a minimum amount of demand for the token. Combined with future plans for burning coins, price is expected to maintain an upward bias, although it has suffered along with the broader market in 2018 and more recently during the summer of 2019. It was unfortunate in 2020 that a beginning rally was cut short by the coronavirus pandemic, although the token has stabilized as of April 2020, and there are hopes the rally could resume in the summer of 2020.
2.1 HOW ARE KNC TOKENS PRODUCED?
The native token of Kyber is called Kyber Network Crystals (KNC). All reserves are required to pay fees in KNC for the right to manage reserves. The KNC collected as fees are either burned and taken out of the total supply or awarded to integrated dapps as an incentive to help them grow.
2.2 HOW DO YOU GET HOLD OF KNC TOKENS?
Kyber Swap can be used to buy ETH directly using a credit card, which can then be used to swap for KNC. Besides Kyber itself, exchanges such as Binance, Huobi, and OKex trade KNC.
2.3 WHAT CAN YOU DO WITH KYBER?
The most direct and basic function of Kyber is for instantly swapping tokens without registering an account, which anyone can do using an Etheruem wallet such as MetaMask. Users can also create their own reserves and contribute funds to a reserve, but that process is still fairly technical one–something Kyber is working on making easier for users in the future.
2.4 THE GOAL OF KYBER THE FUTURE
The goal of Kyber in the coming years is to solidify its position as a one-stop solution for powering liquidity and token swapping on Ethereum. Kyber plans on a major protocol upgrade called Katalyst, which will create new incentives and growth opportunities for all stakeholders in their ecosystem, especially KNC holders. The upgrade will mean more use cases for KNC including to use KNC to vote on governance decisions through a decentralized organization (DAO) called the KyberDAO. With our upcoming Katalyst protocol upgrade and new KNC model, Kyber will provide even more benefits for stakeholders. For instance, reserves will no longer need to hold a KNC balance for fees, removing a major friction point, and there will be rebates for top performing reserves. KNC holders can also stake their KNC to participate in governance and receive rewards.
2.5 BUYING & STORING KNC
Those interested in buying KNC tokens can do so at a number of exchanges. Perhaps your best bet between the complete list is the likes of Coinbase Pro and Binance. The former is based in the USA whereas the latter is an offshore exchange. The trading volume is well spread out at these exchanges, which means that the liquidity is not concentrated and dependent on any one exchange. You also have decent liquidity on each of the exchange books. For example, the Binance BTC / KNC books are wide and there is decent turnover. This means easier order execution. KNC is an ERC20 token and can be stored in any wallet with ERC20 support, such as MyEtherWallet or MetaMask. One interesting alternative is the KyberSwap Android mobile app that was released in August 2019. It allows for instant swapping of tokens and has support for over 70 different altcoins. It also allows users to set price alerts and limit orders and works as a full-featured Ethereum wallet.
2.6 KYBER KATALYST UPGRADE
Kyber has announced their intention to become the de facto liquidity layer for the Decentralized Finance space, aiming to have Kyber as the single on-chain endpoint used by the majority of liquidity providers and dApp developers. In order to achieve this goal the Kyber Network team is looking to create an open ecosystem that garners trust from the decentralized finance space. They believe this is the path that will lead the majority of projects, developers, and users to choose Kyber for liquidity needs. With that in mind they have recently announced the launch of a protocol upgrade to Kyber which is being called Katalyst. The Katalyst upgrade will create a stronger ecosystem by creating strong alignments towards a common goal, while also strengthening the incentives for stakeholders to participate in the ecosystem. The primary beneficiaries of the Katalyst upgrade will be the three major Kyber stakeholders: 1. Reserve managers who provide network liquidity; 2. dApps that connect takers to Kyber; 3. KNC holders. These stakeholders can expect to see benefits as highlighted below: Reserve Managers will see two new benefits to providing liquidity for the network. The first of these benefits will be incentives for providing reserves. Once Katalyst is implemented part of the fees collected will go to the reserve managers as an incentive for providing liquidity. This mechanism is similar to rebates in traditional finance, and is expected to drive the creation of additional reserves and market making, which in turn will lead to greater liquidity and platform reach. Katalyst will also do away with the need for reserve managers to maintain a KNC balance for use as network fees. Instead fees will be automatically collected and used as incentives or burned as appropriate. This should remove a great deal of friction for reserves to connect with Kyber without affecting the competitive exchange rates that takers in the system enjoy. dApp Integrators will now be able to set their own spread, which will give them full control over their own business model. This means the current fee sharing program that shares 30% of the 0.25% fee with dApp developers will go away and developers will determine their own spread. It’s believed this will increase dApp development within Kyber as developers will now be in control of fees. KNC Holders, often thought of as the core of the Kyber Network, will be able to take advantage of a new staking mechanism that will allow them to receive a portion of network fees by staking their KNC and participating in the KyberDAO.
2.7 COMING KYBERDAO
With the implementation of the Katalyst protocol the KNC holders will be put right at the heart of Kyber. Holders of KNC tokens will now have a critical role to play in determining the future economic flow of the network, including its incentive systems. The primary way this will be achieved is through KyberDAO, a way in which on-chain and off-chain governance will align to streamline cooperation between the Kyber team, KNC holders, and market participants. The Kyber Network team has identified 3 key areas of consideration for the KyberDAO: 1. Broad representation, transparent governance and network stability 2. Strong incentives for KNC holders to maintain their stake and be highly involved in governance 3. Maximizing participation with a wide range of options for voting delegation Interaction between KNC Holders & Kyber This means KNC holders have been empowered to determine the network fee and how to allocate the fees to ensure maximum network growth. KNC holders will now have three fee allocation options to vote on: - Voting Rewards: Immediate value creation. Holders who stake and participate in the KyberDAO get their share of the fees designated for rewards. - Burning: Long term value accrual. The decreasing supply of KNC will improve the token appreciation over time and benefit those who did not participate. - Reserve Incentives:Value creation via network growth. By rewarding Kyber reserve managers based on their performance, it helps to drive greater volume, value, and network fees.
2.8 TRANSPARENCY AND STABILITY
The design of the KyberDAO is meant to allow for the greatest network stability, as well as maximum transparency and the ability to quickly recover in emergency situations. Initally the Kyber team will remain as maintainers of the KyberDAO. The system is being developed to be as verifiable as possible, while still maintaining maximum transparency regarding the role of the maintainer in the DAO. Part of this transparency means that all data and processes are stored on-chain if feasible. Voting regarding network fees and allocations will be done on-chain and will be immutable. In situations where on-chain storage or execution is not feasible there will be a set of off-chain governance processes developed to ensure all decisions are followed through on.
2.9 KNC STAKING AND DELEGATION
Staking will be a new addition and both staking and voting will be done in fixed periods of times called “epochs”. These epochs will be measured in Ethereum block times, and each KyberDAO epoch will last roughly 2 weeks. This is a relatively rapid epoch and it is beneficial in that it gives more rapid DAO conclusion and decision-making, while also conferring faster reward distribution. On the downside it means there needs to be a new voting campaign every two weeks, which requires more frequent participation from KNC stakeholders, as well as more work from the Kyber team. Delegation will be part of the protocol, allowing stakers to delegate their voting rights to third-party pools or other entities. The pools receiving the delegation rights will be free to determine their own fee structure and voting decisions. Because the pools will share in rewards, and because their voting decisions will be clearly visible on-chain, it is expected that they will continue to work to the benefit of the network.
After the September 2017 ICO, KNC settled into a trading price that hovered around $1.00 (decreasing in BTC value) until December. The token has followed the trend of most other altcoins — rising in price through December and sharply declining toward the beginning of January 2018. The KNC price fell throughout all of 2018 with one exception during April. From April 6th to April 28th, the price rose over 200 percent. This run-up coincided with a blog post outlining plans to bring Bitcoin to the Ethereum blockchain. Since then, however, the price has steadily fallen, currently resting on what looks like a $0.15 (~0.000045 BTC) floor. With the number of partners using the Kyber Network, the price may rise as they begin to fully use the network. The development team has consistently hit the milestones they’ve set out to achieve, so make note of any release announcements on the horizon.
The 0x project is the biggest competitor to Kyber Network. Both teams are attempting to enter the decentralized exchange market. The primary difference between the two is that Kyber performs the entire exchange process on-chain while 0x keeps the order book and matching off-chain. As a crypto swap exchange, the platform also competes with ShapeShift and Changelly.
