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.


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.


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. 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.
  2. 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.
  3. 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.


Kyber’s founders are Loi Luu, Victor Tran, Yaron Velner — CEO, CTO, and advisor to the Kyber Network.


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.


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


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.


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.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.
see for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).
To see the process of how Tendermint works please see this diagram as well as more info here


Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
In Hub governance all stakers vote, the validators vote is superseded if the delegator votes directly
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.
Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.
There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.

IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.
This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

Weekly Dev Update #20

THORChain Weekly Dev Update for Week 03–09 Dec 2019



The team believe the current bottleneck to THORChain’s decentralisation is the number of nodes that can participate in a single TSS signing ceremony. As the number of participants grows, the complexity becomes exponential. This is in part because THORChain uses a TSS scheme that has no trusted dealer, which is a non-negotiable aspect. The team scoped out two features this week to address this.

Multi-realm Asgard

Instead of a single Asgard with 66 of 99 participating, Asgard can be broken up into different realms, each with a smaller participation number, such as three 22 of 33 realms. This also means that each realm can be rolled at different times, increasing the availability of the network. THORChain has no opinion on where funds are located, they just have to exist and be accounted for in the network. A Multi-realm Asgard does not change any security characteristics of the network, rather it works to shard the funds and increase the scalability. With Multi-realm Asgard, TSS scalability is no longer a concern, instead the upper limit of nodes now becomes a Tendermint scalability issue. Cosmos Hub is working hard to solve this, recently increasing their node count to 125, and with 300 as their long-term target.

TSS Timeout

The trigger to shard Asgard into smaller realms will no longer be a hard-coded number, instead it will be triggered when the key-gen process in a new vault times out after 10 minutes. This means that if the TSS key-generation process for the increased participation number takes too long, it should be sharded. This prevents the network ever generating a committee size with too many members. 10 minutes was chosen as the cutoff due to diminishing returns above that, and a pre-existing shelling point existing on that particular time-point, thanks to Bitcoin.

Trailing Gas Fee

A 1 Rune Fee was hard-coded into THORChain a week ago as the simple solution to a hard problem. The community had a lot of feedback about this, mainly concerns about ease of updating this in future, and they were correct. THORChain must take the governance-minimal approach to all things, and as a result a programmatic solution has been scoped out. The Network Fee will now be twice the 7-day trailing average of gas fees. This will ensure that it always exceeds the expected gas, and drives long-term income into the system. Currently it is global, but it could easily become chain-specific.

Incentive Pendulum

The system is theoretically unsafe when staked assets exceed bonded assets, whether a cartel exists or not. The reason is that a single node could craft an outgoing transaction that spends asset equally to other defecting nodes, and assuming profit-seeking entities, the assumptions around mutually assured destruction no longer hold. While incredibly unlikely to happen, since defecting nodes would need a modified binary to facilitate this transaction and be able to communicate, the system should protect around this edge case. The solution is to disencentivise staking as the system approaches the edge, so that staking rates reduce and the system becomes safe again. The only tool at the system’s disposal is incentives, and the approach is reduce pool rewards and increase bond rewards. This is known as the “Incentive Pendulum”, designed to keep the system at its happy centre; 67% bonded and 33% staked. The Incentive Pendulum also works in the other direction, increasing incentives to stake at high bond rates. The equation is: poolRewards = (y + x) / (y — x), where x = totalStaked, y = totalBonded. * At exactly 50% bonded and 50% staked, pool rewards will be 0%, incentivising bonding. * At 67% bonded and 33% staked, pool rewards will be 33%, the intended amount. * At 100% bonded and 0% staked, pool rewards will be 100%, incentivising staking.

Removal of Hard-coded Constants

The team intend to remove as many constants as possible from the constants.go file, and replace them with programmatic logic. TSS Timeout, Trailing Gas Fees and Churn Heights help solve this. The team will continue the effort.


Cosmos was upgraded to the latest version, allowing the team to begin removing uint64 casting and replacing it with BigInt casting which is better when handling large numbers. The team are also in the process of removing float64 from the codebase, which is unsafe when computed on different machines. * [Upgrade] upgrade to cosmos v0.37.4 * [Bug] fix code coverage counter * stabilize smoke test runs * 224-issue fix validator meta keeper * panic on genesis * Add SafeDivision and removes Float * Resolve: Remove Stake Validation * Resolve “Add min bond requirement” * Resolve “ADD: Incentive Pendulum” * 264-issue fix the way how we broadcast tx to binance RPC host * [Add] Slash bond on bond refund * [Bug] Track gas in yggdrasil vaults * 233-issue add stake handler * add 30 sec timeout to wait for binance txs * Work continues to refactor the codebase to be more modular, testable and easier to grok. * [Refactor] Add unit tests to node account keeper * Resolve “[Refactor] Yggdrasil keeper” * Resolve “[Refactor] Vault Data keeper” * [Refactor] pool addresses keeper * 220-issue refactor Reserve Contributor * [Refactor] observer keeper * Resolve “[Refactor] Pool Staker keeper” * [Refactor] Pool keeper * [Refactor] Staker pool keeper * [Refactor] tx in keeper * [Refactor] reserve contributor handler * [Refactor] Rewrite tx in handler, msg, etc * Resolve “[Refactor] handleMsgBond” * Resolve “[Refactor] handleMsgAck” * [Refactor] add mock txout store * [Refactor] create pool address manager interface * [Refactor] create mock validator manager * Resolve “[Refactor] handleMsgLeave” * Resolve “[Refactor] handleMsgAdd” * [Refactor] version handler * refactor-stake unit tests * [Refactor] TxOutStore * 236-issue handler unstake * [Refactor] Breakout TxIn into two handlers * Resolve “[Refactor] handleMsgConfirmNextPoolAddress”

Bifröst Module

Work begins on the feature/bifrostv2 branch, which is a chain-agnostic Bifröst Module that will be verified to work on Binance Chain, Bitcoin, Ethereum prior to mainnet. Monero has also been scoped out, but testing it may not happen prior to mainnet.


The team will soon move away from signalling dates for releases, instead will work to signal around completion status of milestones. Whilst ChaosNet seems to be on time for 03 January, much is left to be done: * [ChaosNet] Artificial Ragnarok * [ChaosNet] 1 Day rotations * Add bond reward events * Create pubkeys endpoint * [ChaosNet] Cap staked rune at 600k * Versionize the constants * Emit Validator Events * THORNode Telegram Bot

Sup folks! Here’s your week at Parachute + partners (4 Oct - 10 Oct'19):

First off, super congratulations to Alexis for becoming a Parachute admin. Woot woot! In the words of Cap: "Long overdue and much appreciated!". Doc Victor hosted a games trivia in Tiproom with 2500 $PAquestion prize. 10 questions. Charlotte’s Math and Voice Clip trivia in Tiproom were another 10 Qs each at 2500 $PAR per Q. Sweet. Ian got $PAR listed in the newly launched McAfeeDex (more on that later). Thank ya Ian! Cryptopreneurs looking for some guidance? Check out Cap’s recommended reading for the week – Haseeb Qureshi of Dragonfly Capital talks about how "pretty much everyone is winging it", how that's part of the journey and how to move from a maybe to a sure thing. Cap says the article “has a hundred powerful little points for building a company (in any space really) that resonate through what we do here at Parachute”. Great stuff! Parachute announced a partnership with Pynk this week. Pynk is an investment platform that uses crowd wisdom to make investment decisions. They will be using ParJar to share USDC and PAR with their community. Welcome on board Pynksters!

Victor’s 10 question Friday trivia at aXpire had a 100 $AXPR prize for each question. Neat! Click here to watch the latest weekly recap from aXpire. The new Resolvr promo video was launched. The Resolvr and Bilr twitter handles were started as well. This week’s $AXPR burn saw 200k tokens removed from total supply permanently. CEO Gary Markham was interviewed by PetaCrunch. 2gether’s Crypto Talent contest got coverage from Being Crypto. Founder Salvador recorded training videos for participants of the contest. The platform was featured in an article on Merca2. Spanish speakers, have a look! Emprende TVE did a quick mention, as the team bid farewell to South Summit and travelled to Freshworks Inc's Experience Roadshow. Read up on CEO Ramon’s thoughts on Facebook’s Libra in this Forbes article published this week. The XIO community voted to keep the twitter public in order to keep content available to non-citizens as well. As part of the Binance Dex listing proposal*, the team continued to answer queries raised by the BNB community. Great bit of chatter on the thread on how the XIO ecosystem will work. Andrew (cryptocoindude) wrote a review of the BOMB project which came out this week.
\[As already shared, the switch to Binance Chain has been shelved. $XIO will continue stay on Ethereum chain. But there will still be a token swap. Details will be shared in a future update]*
Bilr UX: simple and intuitive
The $ETHOS to $VGX rebrand requires collaboration from a large set of partners. In line with this, Shingo announced the Rebrand Partner Program. Plus, a shoutout to Voyager from Scott Melker in his CoinTelegraph article was the perfect way to cap off the week. SelfKey is officially out of beta with the latest update. You can read all about it in the detailed article on SelfKey v1.3.0. Also, a summary of all that has happened in September can be found here. We have covered most of these in previous updates. John McAfee launched his self branded decentralised exchange McAfeeDex. This is the first white label Dex built on the SwitchDex contract. Massive! The news was featured on CoinTelegraph, Decrypt,, AMBCrypto, Bitcoinist, Block Publisher, Coinspeaker and U.Today. Here’s a guide on how to use the Dex. The smart contract and front end is open sourced and there are bounties to BUIDL more fun stuff on it. Listing any ERC20 on the McAfeeDex is free and the Dex will support more blockchains in the future. SwitchDex will also be offering anyone the chance to launch their own Dex’es called portals built on their smart contract. Click here to see how. Platform fees from McAfeeDex will be distributed to exchange operators and ESH and SDEX token holders. Want to spend a day with the man himself? Get in on the ESH Trading Competition! Also, the social media bounties were distributed this week.
McAfeeDex vs Others. Check the last row. Haha
For the technically inclined, Andre Cronje’s latest post explains Fantom’s current project status. A community member got Uptrennd’s $1UP token listed on McAfeeDex. Uptrennd underwent some upgrades this week while the community partied on Meme Monday. $1UP deposits are now live on the platform. Plus, a few other updates can be seen here. There’s also a post to read all the details on the deposit feature. Along with the consistent rise in Alexa rankings, Google ranking has steadily gone up as well. Congrats! Here’s looking at you Uptrennd crew! Amazing crypto success story of the week has to be Jarau’s journey of buying a laptop with his earned points on the platform. Even Altcoin Magazine featured this. Big up to ya Jarau! Catch up with the latest District Weekly from District0x by clicking here. Hydro entered into a partnership with OmiseGo to make use of their plasma chain tech so that Hydro Pay doesn’t stall even when Ethereum chain slows down. Biz Dev Mark Anstead was also in DevCon5 in Osaka this week to spread the word on Hydro and to demo OmiseGo’s plasma implementation in Hydro Pay at $OMG’s booth. As the Hydro crew prepared for their webinar on financial wellness to be held in a few weeks, their article on this hit the stands. Co-Founder Mike Kane also wrote about its use-cases and about accelerating of fintech innovation in an Oracle blog post. This week we got to see another sneak peek into the Hydro Vault which is currently under development. Super slick! KPMG Turkey became a certified member of the Hydro Partner Program. This will allow them to offer all Hydrogen solutions to their enterprise clients. Noice!
Hydro Vault is sure to grab some major eyeballs
As part of its Notary Consilium, Silent Notary set up a dedicated Telegram group for this. In the run up to DevCon5 at Osaka, beta testing of OST’s Pepo app saw it become the #1 non-game Ethereum dApp. Awesomeness! The formal live beta launch of Pepo saw founder Jason Goldberg and co-founder Benjamin Bollen introduce the app for the first time at Building the New Web and EthPlanet Lightning Talks events to DevCon5 attendees. Don’t forget to get the app today in order to catch your favourite crypto thought leader on there – from Bobby Ong to Amanda Gutterman to Jordan Spence and many more. The launch of Pepo was also covered by Decrypt in a feature article. Click here for pics from the Pepo sponsored Shabu Shabu dinner and pub crawl. Fun! And if you were in Osaka, hope you didn’t miss the Crypto Grows on Trees art exhibition. Another event sponsored by Pepo. Also, Pepo stats can be tracked on the OSTWatch as well. This week at Constellation involved the core team sharing insights about the project on various platforms. Co-Founder Ben Jorgensen shared some quick thoughts on how the team works on BizDev that makes it stand out from the rest. BD VP Benjamin Diggles travelled to Oregon Venture Blockchain Studio Demo Day to talk about $DAG. Read up on VP of Finance Mathis Goldmann's thoughts on Constellation's role in the future of blockchain - "The solution to this issue (of scalability) is third generation horizontally scalable blockchains like Constellation…". Ben’s interview with FomoHunt had a few easter eggs (*cough partnerships *cough) peppered in between. The Daily Chain covered the project in a detailed feature. Tons of $BAGS tokens were given away this week in a community-based SWOT analysis sprint on the project. Also, here’s a call-to-action for content creators. BAGS is looking for you. Collab opportunity FTW!

And with that, it’s a wrap. See you again soon with another exciting update. Bye!

Chainlink wont come up in Ledger Nano S

Last January my cousin turned me onto Chainlink and I bought some and put it on my Ledger Nano S along with a few other coins i had purchased. I kinda forgot about it until recently when my wife and i decided to buy some more Bitcoin so I decided i wanted to unload it and the small weekly buy i have out of my coinbase account and onto the Ledger.

It had been a long time since i turned my Ledger on so there were a few updates and memory refreshers i had to iron out but i was able to access all my coins except my ChainLink.

I went onto and plugged in my ledger and when it opened up, I just got a bunch of random empty wallet addresses. I could look through all of them but the list seemed endless. and they were all empty as far as i could tell. So i retraced my steps and went to my Binance account where I found the address the tokens were sent to and the transaction ID. I then looked up the address on and it is showing my Chainlink and my transaction from that day and nothing else. No other transactions and the Chainlink is there. But i cant access this address anywhere on my Ledger. I cant find it or seem to find a way to search via address name. Just a whole lot of empty ETH wallets with different addresses. I tried the vintage MEW and the new one and I kept getting the same results.

So this was a long time ago, I was buying a bunch of random coins and I'm a regular "trees" guy so my memory may be failing me, but I am 99.9 percent sure that that address was to a wallet on my Ledger. The reason i say that is because I am a hodler. And believe me, I am currently hodling onto way worse coins than this ChainLink. The only reason i would have moved this Chainlink from my Binance account would have been to either store it or cash it out. But i couldn't have cashed it out because the wallet is still showing the balance of the tokens.

Am i missing something here? Is there something on the Ledger i am forgetting to switch the setting on for it to show my balance? I recall doing this process before but i must be missing something. Or is there a way for me to verify that this address is actually on my Ledger? I am pretty sure it is, but i could be wrong. I could have put them in a placeholder somewhere but i dont think i would have done that because i have never done that before lol but now i am questioning everything.

I agree I am probably sounding like a stupid noob, because boy do i feel stupid. But as far as i can tell, all I can prove is that last year i sent some ChainLink from my Binance wallet to another wallet and it is still there. Am i wrong about that too?

If i am not wrong, then i am pretty confident that wallet is on my Ledger and i am just unable to access it for some reason. Is there something i am doing wrong on the technical side? Why cant i see it?

Thanks guys

Daily analysis of cryptocurrencies 20191102 (Market index 50 — Neutral state)

Daily analysis of cryptocurrencies 20191102 (Market index 50 — Neutral state)

Crypto Custody Firm Xapo Initiated 5 Whale Transfers On Nov 1 Citing data from the Bejijing-based blockchain security company Chainsguard, the Bitcoin network witnessed multiple whale transfers on Nov 1. At 21:10:38 UTC on Nov 1, Xapo, a Bitcoin custody service provider, has conducted five whale transfers with the largest amount within one transfer marking up to 20,000 BTC. The total number of moved BTC in these transfers records 65822.01. Many of these BTC originated from the transfers of 4,999 to 10,000 BTC collected by Xapo on the Bitcoin chain at 19:19:49 and 19:32:12 on the same day. One of the main BTC sources initiated by the address starting with 37whD5 was crypto exchange Bitstamp. Previously, the above-mentioned exchange announced that its custodian would change to BitGo. Otherwise, Bitstamp had a great transfer with more than 110,000 BTC involved on October 15. At 20:53:20 on Nov 1, the wallet address beginning with 3AdpZc initiated a transfer of 5000 BTC to the exchange Poloniex. After analysis, the source can be traced back to the coins accumulated by Poloniex in March 2016. Generally speaking, the whale transfer carried out by institutions comes from the needs of business or customers. Sometimes, it is only the planned wallet management.
Utah To Facilitate Voting For Disabled Individuals Through Blockchains Recent reports indicate that blockchain technology will soon be used in Utah, as part of a trial project meant to allow disabled individuals to cast their votes. To put things into perspective, the local council and government of Utah have decided to allow blockchain-based voting via smartphones in the upcoming municipal election that will take place in November. The platform that disabled voters will be using for this election represents the result of a fruitful partnership between the Utah Country Elections Division, the National Cybersecurity Centre, Tusk Philanthropies and Voatz, a local voting app development company.
Ethereum To Increase The Blocksize By 8x Ethereum is partially addressing the many complexities of sharding by simply increasing the blocksize from the equivalent of about 1MB every ten minutes to circa 8MB. Danny Ryan, the Ethereum 2.0 coordinator, publicly said: “We are making the blocks bigger based on recent research on safe block size and propagation times, so the data availability of the system is still > 1MB/s so you can still get similar scalability gains when doing things like ZKrollup and OVM.” ZK rollups are a hybrid scaling method that combines on-chain security and second layer networks through smart contracts and zero knowledge methods. OVM is the Optimistic Virtual Machine from Plasma, with both being more sort of on top of Ethereum’s public blockchain.

During the first quarter of the year, Bitcoin was trapped inside a tight trading range, where major players began buying the fear of retail crypto investors and accumulating the asset at the lowest possible prices.
Starting in the second quarter, the first-ever crypto asset rocketed up from that trading range, and went on a parabolic rally that didn’t stop until Bitcoin met former bear market resistance at $14,000 where it was rejected.
After three consecutive red monthly candles in a row, October closed green and kept a potential bull flag formation on monthly price charts intact, giving bulls hope that the crypto asset’s 2019 rally isn’t totally finished.
