ABSTRACTIn 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.
1.INTRODUCTIONDeFi 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 PROTOCOLThe 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:
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 PROTOCOLThe 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
1.3 KYBER CORE SMART CONTRACTSKyber 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 RESERVEAnyone 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 ROLESThere 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 TRADEA 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 TRADEA 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) TOKENKyber 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 FUTUREThe 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 KNCThose 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 UPGRADEKyber 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 KYBERDAOWith 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 STABILITYThe 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 DELEGATIONStaking 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.
3. TRADINGAfter 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.
4. COMPETITIONThe 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.

This is Part 1 of the serialized articles aimed to explain the Tendermint consensus protocol in detail.
Part 1. Preliminary of the consensus protocol: security model and PBFT protocol
Part 2. Tendermint consensus protocol illustrated: two-phase voting protocol and the locking and unlocking mechanism
Part 3. Weighted round-robin proposer selection algorithm used in Tendermint project
Any consensus agreement that is ultimately reached is the General Agreement, that is, the majority opinion. The consensus protocol on which the blockchain system operates is no exception. As a distributed system, the blockchain system aims to maintain the validity of the system. Intuitively, the validity of the blockchain system has two meanings: firstly, there is no ambiguity, and secondly, it can process requests to update its status. The former corresponds to the safety requirements of distributed systems, while the latter to the requirements of liveness. The validity of distributed systems is mainly maintained by consensus protocols, considering the multiple nodes and network communication involved in such systems may be unstable, which has brought huge challenges to the design of consensus protocols.
The semi-synchronous network model and Byzantine fault toleranceResearchers of distributed systems characterize these problems that may occur in nodes and network communications using node failure models and network models. The fail-stop failure in node failure models refers to the situation where the node itself stops running due to configuration errors or other reasons, thus unable to go on with the consensus protocol. This type of failure will not cause side effects on other parts of the distributed system except that the node itself stops running. However, for such distributed systems as the public blockchain, when designing a consensus protocol, we still need to consider the evildoing intended by nodes besides their failure. These incidents are all included in the Byzantine Failure model, which covers all unexpected situations that may occur on the node, for example, passive downtime failures and any deviation intended by the nodes from the consensus protocol. For a better explanation, downtime failures refer to nodes’ passive running halt, and the Byzantine failure to any arbitrary deviation of nodes from the consensus protocol.
Compared with the node failure model which can be roughly divided into the passive and active models, the modeling of network communication is more difficult. The network itself suffers problems of instability and communication delay. Moreover, since all network communication is ultimately completed by the node which may have a downtime failure or a Byzantine failure in itself, it is usually difficult to define whether such failure arises from the node or the network itself when a node does not receive another node's network message. Although the network communication may be affected by many factors, the researchers found that the network model can be classified by the communication delay. For example, the node may fail to send data packages due to the fail-stop failure, and as a result, the corresponding communication delay is unknown and can be any value. According to the concept of communication delay, the network communication model can be divided into the following three categories:
The design and selection of consensus protocols for public chain networks that allow nodes to dynamically join and leave need to consider possible Byzantine failures. Therefore, the consensus protocol of a public chain network is designed to guarantee the security and liveness of the network under the semi-synchronous network model on the premise of possible Byzantine failure. Researchers of distributed systems point out that to ensure the security and liveness of the system, the consensus protocol itself needs to meet three requirements:
The CAP theorem and Byzantine Generals ProblemIn a semi-synchronous network, is it possible to design a Byzantine fault-tolerant consensus protocol that satisfies validity, agreement, and termination? How many Byzantine nodes can a system tolerance? The CAP theorem and Byzantine Generals Problem provide an answer for these two questions and have thus become the basic guidelines for the design of Byzantine fault-tolerant consensus protocols.
Lamport, Shostak, and Pease abstracted the design of the consensus mechanism in the distributed system in 1982 as the Byzantine Generals Problem, which refers to such a situation as described below: several generals each lead the army to fight in the war, and their troops are stationed in different places. The generals must formulate a unified action plan for the victory. However, since the camps are far away from each other, they can only communicate with each other through the communication soldiers, or, in other words, they cannot appear on the same occasion at the same time to reach a consensus. Unfortunately, among the generals, there is a traitor or two who intend to undermine the unified actions of the loyal generals by sending the wrong information, and the communication soldiers cannot send the message to the destination by themselves. It is assumed that each communication soldier can prove the information he has brought comes from a certain general, just as in the case of a real BFT consensus protocol, each node has its public and private keys to establish an encrypted communication channel for each other to ensure that its messages will not be tampered with in the network communication, and the message receiver can also verify the sender of the message based thereon. As already mentioned, any consensus agreement ultimately reached represents the consensus of the majority. In the process of generals communicating with each other for an offensive or retreat, a general also makes decisions based on the majority opinion from the information collected by himself.
According to the research of Lamport et al, if there are 1/3 or more traitors in the node, the generals cannot reach a unified decision. For example, in the following figure, assume there are 3 generals and only 1 traitor. In the figure on the left, suppose that General C is the traitor, and A and B are loyal. If A wants to launch an attack and informs B and C of such intention, yet the traitor C sends a message to B, suggesting what he has received from A is a retreat. In this case, B can't decide as he doesn't know who the traitor is, and the information received is insufficient for him to decide. If A is a traitor, he can send different messages to B and C. Then C faithfully reports to B the information he received. At this moment as B receives conflicting information, he cannot make any decisions. In both cases, even if B had received consistent information, it would be impossible for him to spot the traitor between A and C. Therefore, it is obvious that in both situations shown in the figure below, the honest General B cannot make a choice.
According to this conclusion, when there are $n$ generals with at most $f$ traitors (n≤3f), the generals cannot reach a consensus if $n \leq 3f$; and with $n > 3f$, a consensus can be reached. This conclusion also suggests that when the number of Byzantine failures $f$ exceeds 1/3 of the total number of nodes $n$ in the system $f \ge n/3$ , no consensus will be reached on any consensus protocol among all honest nodes. Only when $f < n/3$, such condition is likely to happen, without loss of generality, and for the subsequent discussion on the consensus protocol, $ n \ge 3f + 1$ by default.
The conclusion reached by Lamport et al. on the Byzantine Generals Problem draws a line between the possible and the impossible in the design of the Byzantine fault tolerance consensus protocol. Within the possible range, how will the consensus protocol be designed? Can both the security and liveness of distributed systems be fully guaranteed? Brewer provided the answer in his CAP theorem in 2000. It indicated that a distributed system requires the following three basic attributes, but any distributed system can only meet two of the three at the same time.
A distributed system aims to provide consistent services. Therefore, the consistency attribute requires that the two nodes in the system cannot provide conflicting status information or expired information, which can ensure the security of the distributed system. The availability attribute is to ensure that the system can continuously update its status and guarantee the availability of distributed systems. The partition tolerance attribute is related to the network communication delay, and, under the semi-synchronous network model, it can be the status before GST when the network is in an asynchronous status with an unknown delay in the network communication. In this condition, communicating nodes may not receive information from each other, and the network is thus considered to be in a partitioned status. Partition tolerance requires the distributed system to function normally even in network partitions.
The proof of the CAP theorem can be demonstrated with the following diagram. The curve represents the network partition, and each network has four nodes, distinguished by the numbers 1, 2, 3, and 4. The distributed system stores color information, and all the status information stored by all nodes is blue at first.
The discovery of the CAP theorem seems to declare that the aforementioned goals of the consensus protocol is impossible. However, if you’re careful enough, you may find from the above that those are all extreme cases, such as network partitions that cause the failure of information transmission, which could be rare, especially in P2P network. In the second case, the system rarely returns the same information with node 2, and the general practice is to query other nodes and return the latest status as believed after a while, regardless of whether it has received the request information of other nodes. Therefore, although the CAP theorem points out that any distributed system cannot satisfy the three attributes at the same time, it is not a binary choice, as the designer of the consensus protocol can weigh up all the three attributes according to the needs of the distributed system. However, as the communication delay is always involved in the distributed system, one always needs to choose between availability and consistency while ensuring a certain degree of partition tolerance. Specifically, in the second case, it is about the value that node 2 returns: a probably outdated value or no value. Returning the possibly outdated value may violate consistency but guarantees availability; yet returning no value deprives the system of availability but guarantees its consistency. Tendermint consensus protocol to be introduced is consistent in this trade-off. In other words, it will lose availability in some cases.
The genius of Satoshi Nakamoto is that with constraints of the CAP theorem, he managed to reach a reliable Byzantine consensus in a distributed network by combining PoW mechanism, Satoshi Nakamoto consensus, and economic incentives with appropriate parameter configuration. Whether Bitcoin's mechanism design solves the Byzantine Generals Problem has remained a dispute among academicians. Garay, Kiayias, and Leonardos analyzed the link between Bitcoin mechanism design and the Byzantine consensus in detail in their paper The Bitcoin Backbone Protocol: Analysis and Applications. In simple terms, the Satoshi Consensus is a probabilistic Byzantine fault-tolerant consensus protocol that depends on such conditions as the network communication environment and the proportion of malicious nodes' hashrate. When the proportion of malicious nodes’ hashrate does not exceed 1/2 in a good network communication environment, the Satoshi Consensus can reliably solve the Byzantine consensus problem in a distributed environment. However, when the environment turns bad, even with the proportion within 1/2, the Satoshi Consensus may still fail to reach a reliable conclusion on the Byzantine consensus problem. It is worth noting that the quality of the network environment is relative to Bitcoin's block interval. The 10-minute block generation interval of the Bitcoin can ensure that the system is in a good network communication environment in most cases, given the fact that the broadcast time of a block in the distributed network is usually just several seconds. In addition, economic incentives can motivate most nodes to actively comply with the agreement. It is thus considered that with the current Bitcoin network parameter configuration and mechanism design, the Bitcoin mechanism design has reliably solved the Byzantine Consensus problem in the current network environment.
Practical Byzantine Fault Tolerance, PBFTIt is not an easy task to design the Byzantine fault-tolerant consensus protocol in a semi-synchronous network. The first practically usable Byzantine fault-tolerant consensus protocol is the Practical Byzantine Fault Tolerance (PBFT) designed by Castro and Liskov in 1999, the first of its kind with polynomial complexity. For a distributed system with $n$ nodes, the communication complexity is $O(n2$.) Castro and Liskov showed in the paper that by transforming centralized file system into a distributed one using the PBFT protocol, the overwall performance was only slowed down by 3%. In this section we will briefly introduce the PBFT protocol, paving the way for further detailed explanations of the Tendermint protocol and the improvements of the Tendermint protocol.
The PBFT protocol that includes $n=3f+1$ nodes can tolerate up to $f$ Byzantine nodes. In the original paper of PBFT, full connection is required among all the $n$ nodes, that is, any two of the n nodes must be connected. All the nodes of the network jointly maintain the system status through network communication. In the Bitcoin network, a node can participate in or exit the consensus process through hashrate mining at any time, which is managed by the administrator, and the PFBT protocol needs to determine all the participating nodes before the protocol starts. All nodes in the PBFT protocol are divided into two categories, master nodes, and slave nodes. There is only one master node at any time, and all nodes take turns to be the master node. All nodes run in a rotation process called View, in each of which the master node will be reelected. The master node selection algorithm in PBFT is very simple: all nodes become the master node in turn by the index number. In each view, all nodes try to reach a consensus on the system status. It is worth mentioning that in the PBFT protocol, each node has its own digital signature key pair. All sent messages (including request messages from the client) need to be signed to ensure the integrity of the message in the network and the traceability of the message itself. (You can determine who sent a message based on the digital signature).
The following figure shows the basic flow of the PBFT consensus protocol. Assume that the current view’s master node is node 0. Client C initiates a request to the master node 0. After the master node receives the request, it broadcasts the request to all slave nodes that process the request of client C and return the result to the client. After the client receives f+1 identical results from different nodes (based on the signature value), the result can be taken as the final result of the entire operation. Since the system can have at most f Byzantine nodes, at least one of the f+1 results received by the client comes from an honest node, and the security of the consensus protocol guarantees that all honest nodes will reach consensus on the same status. So, the feedback from 1 honest node is enough to confirm that the corresponding request has been processed by the system.
For the status synchronization of all honest nodes, the PBFT protocol has two constraints on each node: on one hand, all nodes must start from the same status, and on the other, the status transition of all nodes must be definite, that is, given the same status and request, the results after the operation must be the same. Under these two constraints, as long as the entire system agrees on the processing order of all transactions, the status of all honest nodes will be consistent. This is also the main purpose of the PBFT protocol: to reach a consensus on the order of transactions between all nodes, thereby ensuring the security of the entire distributed system. In terms of availability, the PBFT consensus protocol relies on a timeout mechanism to find anomalies in the consensus process and start the View Change protocol in time to try to reach a consensus again.
The figure above shows a simplified workflow of the PBFT protocol. Where C is the client, 0, 1, 2, and 3 represent 4 nodes respectively. Specifically, 0 is the master node of the current view, 1, 2, 3 are slave nodes, and node 3 is faulty. Under normal circumstances, the PBFT consensus protocol reaches consensus on the order of transactions between nodes through a three-phase protocol. These three phases are respectively: Pre-Prepare, Prepare, and Commit:
In the three-phase protocol execution of the PBFT protocol, in addition to maintaining the status information of the distributed system, the node itself also needs to log all kinds of consensus information it receives. The gradual accumulation of logs will consume considerable system resources. Therefore, the PBFT protocol additionally defines checkpoints to help the node deal with garbage collection. You can set a checkpoint every 100 or 1000 sequence numbers according to the request sequence number. After the client request at the checkpoint is executed, the node broadcasts
The three-phase protocol of the PBFT protocol can ensure the consistency of the processing order of the client request, and the checkpoint mechanism is set to help nodes perform garbage collection and further ensures the status consistency of the distributed system, both of which can guarantee the security of the distributed system aforementioned. How is the availability of the distributed system guaranteed? In the semi-synchronous network model, a timeout mechanism is usually introduced, which is related to delays in the network environment. It is assumed that the network delay has a known upper bound after GST. In such condition, an initial value is usually set according to the network condition of the system deployed. In case of a timeout event, besides the corresponding processing flow triggered, additional mechanisms will be activated to readjust the waiting time. For example, an algorithm like TCP's exponential back off can be adopted to adjust the waiting time after a timeout event.
To ensure the availability of the system in the PBFT protocol, a timeout mechanism is also introduced. In addition, due to the potential the Byzantine failure in the master node itself, the PBFT protocol also needs to ensure the security and availability of the system in this case. When the Byzantine failure occurs in the master node, for example, when the slave node does not receive the PRE-PREPARE message or the PRE-PREPARE message sent by the master node from the master node within the time window and is thus determined to be illegitimate, the slave node can broadcast
VIEWCHANGE contains a lot of information. For example, C contains 2f+1 signature information, P contains several signature sets, and each set has 2f+1 signature. At least 2f+1 nodes need to send a VIEWCHANGE message before prompting the system to enter the next new view, and that means, in addition to the complex logic of constructing the information of VIEWCHANGE and NEW-VIEW, the communication complexity of the view conversion protocol is $O(n2$.) Such complexity also limits the PBFT protocol to support only a few nodes, and when there are 100 nodes, it is usually too complex to practically deploy PBFT. It is worth noting that in some materials the communication complexity of the PBFT protocol is inappropriately attributed to the full connection between n nodes. By changing the fully connected network topology to the P2P network topology based on distributed hash tables commonly used in blockchain projects, high communication complexity caused by full connection can be conveniently solved, yet still, it is difficult to improve the communication complexity during the view conversion process. In recent years, researchers have proposed to reduce the amount of communication in this step by adopting aggregate signature scheme. With this technology, 2f+1 signature information can be compressed into one, thereby reducing the communication volume during view change.

Introduction / SummaryThe Quadriga Initiative is an independent process where affected users and businesses in the community work together to recover losses from QuadrigaCX. An exchange (the primary exchange) will verify claims and distribute free tokens representing losses. Tokens will be accepted at the primary exchange and by participating businesses at face value. There is a white paper here with more detail:
If you wish to participate in the Quadriga Initiative and receive free tokens representing your loss, there is a pre-claim process now open. A pre-claim uses your QCX client ID, first name as registered on the QCX platform, and a valid email address to copy your balance information and associate it with your email address.
Although a personal email will work, it is recommended for privacy and security to set up a new "forwarder" email account that doesn't personally identify you, with a unique password. Make sure that whatever email process you set up is one which still works to reach you in a few months time.
Background on the InitiativeMy name is Matt. I’ve lived in Calgary my whole life, and been running businesses and programming since I was 10 years old. I’m a recent graduate of the University of Calgary in a business and computer science double major, and I currently manage the software team (6 students) at a small Calgary IoT startup. My past business experiences include running a window cleaning franchise across 6 communities, a popular concession stand, and a free web hosting service with over 10,000 clients.
I first got involved with cryptocurrency in 2017, when we had the big run up. Prior to that, I’d done a ton of research but never actually invested. While my losses in Quadriga are significant, they’re nowhere near some of the losses I’ve been hearing about. I’m fortunate to be in a “walk away” position if I so choose and I more or less did for the first week. But I couldn’t stay away. It isn’t right. Especially not now when the solution is so close and the potential impact is so significant.
Quadriga Initiative is the result of 6-7 months of intense brainstorming, collaboration, and perpetual iteration around the central problem of how to recover what's been lost.
The money is almost certainly not accessible. (I'm pretty sure it would have been found already.) We'll all get something from the bankruptcy, but for most of us I fear it won't really make up for what was lost. For many people - their whole life savings. It's not a very satisfying recovery. It doesn't leave anyone whole. It leaves a lot of people behind.
Without funds to pull from, any full recovery solution has to center around creating new value. Entrepreneurs and business leaders are creating value every day, and this is where the idea comes from.
We take advantage of the fact we have a large affected user community, tons of economic bargaining power, and a vast network. Many in the business community were affected, know someone who was affected, or feel horrible about what happened. My discussions with business leaders have shown that they generally desire to make this right, and businesses regularly do "goodwill" donations or gestures for marketing. The Quadriga Initiative provides a way businesses can help easily and in a "win win" way by running token-accepting promotions. We then provide a competitive framework that helps to promote businesses which make the biggest impact, highly incentivizing a faster recovery.
At this stage, everything is more or less ready to launch. We have a primary exchange partner, a small team of affected users, and multiple business connections. What remains is the incredibly tough challenge of creating trust and understanding among a community that's been completely devastated in the worst way. This is no easy task.
We need your help! If things don't make sense, or you still have questions, or you don't understand something, please take the time to ask and reach out! In addition to commenting here, please feel free to chat with us on Telegram: https://t.me/QuadrigaInitiative
Where Does the Money Come From?The money (value) comes out of the profit margin of businesses. Businesses normally sell a product or service at a profit over the cost of production. Instead, a business would sell the product or service at a discount (less profit), accepting tokens in place of the difference.
While this may seem generous, like the business is giving something away, it also benefits the business as well:
The leaderboard and large affected user community give a strong advantage to businesses to participate and offer the best deals. Businesses that have recovered the most are rewarded with more people seeing their promotion (free advertising).
The Various Uses For TokensThe Primary Exchange: Tokens will be tradable and accepted at face value towards the trading fees on the primary exchange. A trader who wants to save money on trades can stock up on the tokens to gain a discount over other customers who don't bother. The tokens can be used towards 50%-100% of the trading fees depending on the calendar date. This means a heavy discount for affected users and is more or less a price segment for the exchange.
In addition, the primary exchange partner we have at the moment is looking into giving back a small portion (15%) of gross trading revenue towards cashing tokens. This is done to incentivize the affected user community to spread the word about the exchange.
Participating Businesses: Businesses in the community accept the tokens towards purchases to promote to Quadriga victims, supporters, and deal seekers. It functions similar to a discount, where the tokens are applied as a portion of the sale price, with a few additional advantages for the business:
Token Flow DiagramThe following diagram is a handy visualization of the initiative and how the various parties interact:
Quadriga Initiative Diagram
The complete initiative is a full marketplace, enabling the beneficial (win win) interaction of all parties and the gradual recovery of losses over time. The token supply is finite, limited by the amount of losses we can verify, and all tokens eventually get cashed for $1 worth of products/services (or primary exchange gross trading revenue) as the program runs.
Our Primary Exchange PartnerSince the primary exchange is handling validation and distributing the tokens, it's important they be trustworthy. Given the history with Quadriga, most affected users (including every member of our team) are legitimately concerned about anyone losing their funds again. This is the primary reason we've selected to work with TxQuick.
Proof of Reserves and Why It MattersIn case you missed them, so far this year we've seen 3 large scale exchange collapses:
In the case of QuadrigaCX, it took the freezing of the bank accounts, the death/disappearance of the CEO, and concerted legal action to even realize it was insolvent.
Exchanges can easily continue to operate for years with whatever level of reserves they like. Third party audits are riddled with holes like:
Proof of Reserves asks exchanges to:
Despite the relative simplicity of publishing wallet keys, the vast selection of exchanges we have in Canada, and the many millions of dollars stored, not a single exchange has done so. The hash tree algorithm has existed since 2014. It's presently on one exchange (last audited in 2014).
We feel that Proof of Reserves is the key to preventing future exchange collapses, which is why we are so pleased to have a primary exchange partner which will be implementing the full algorithm. While we can't control other exchanges, traders now have an option to use an exchange which proves full backing of all deposits and we hope this will encourage wider adoption and greater industry transparency.
Timeline for the InitiativeThe initiative process breaks down into roughly 3 stages:
Pre-Claim Stage - We are working to save affected user balances for later validation, as well as determine if there is sufficient interest in the project. This is ongoing.
Exchange Stage - We bring the primary exchange online, and process claims. Recovery starts through exchange trading fee discounts and eventually gross trading revenue. The exchange platform is expected to launch within a few months.
Marketplace Stage - Once we have enough individuals with tokens, we bring in the first businesses from the wider community. After we have several initial businesses, the marketplace grows organically as more businesses sign up over time. This is approximately a year after launching the exchange.
Full recovery (all losses) is likely to take multiple years, anywhere from 3 to 25 years. My best estimate would be 10 years, although there are a lot of factors to consider.
Verification of ClaimsAccurately capturing losses is key. Businesses are interested in helping honest victims of a crime who had their money stolen from them, and not that interested in supporting any fraud. We've been working hard to make our process as easy as possible for affected users, while being as hard as possible for false claims (claiming wrong amounts, losses of others, or fake claims).
