Over the course of mere months, the DeFi space has grown to the tune of billions in 2020. While DeFi has earned its title as the next hottest crypto trend, its popularity has shown to be a double-edged sword. Reports of scams and “rug pulls” have volleyed into crypto news outlets, social media, and discussion groups, damaging the reputation of the DeFi space.
DeFi is unique in that the tenets of trust and decentralization has normalized the practice of anonymity to the point where nearly every single DeFi team launches anonymously. While the freedom to create DeFi tools does support the notion that anyone should be able to create an honest financial protocol for the goodwill of the people, the opposite effect often occurs. If the past few months has proven anything, it’s that the normalization of anonymity has acted as both the greatest weapon and the greatest defence for fraudulent actors and dishonest entities. Because of this, DeFi is often seen as a free-for-all minefield as countless exit scams and “rugpulls” have become the norm. Having this as an accepted vice of DeFi shouldn’t mean investors should normalize risk of losses. It should inspire projects to set a higher standard in the DeFi space.
We are excited to announce that the YFDAI team has taken the tenets of decentralized finance and expanded on them. As a DeFi protocol, we champion decentralization and the collective action of the community to pave the road towards true transparency and security for all. After countless hours of legal counseling, we’re proud to announce that we will be among the very few DeFi projects to go public and among the first to set a new precedent for the DeFi space.
Say hello to the YFDAI team.
Meet Pritha Paul (Olivia) — Chief Strategic — Volunteer
Olivia is both a software engineer and a Businesswoman. Having been an avid fan of blockchain and trader of cryptocurrencies, Olivia felt the need to contribute her expertise to the cryptocurrency space. This desire prompted her to create YFDAI, one of DeFi’s most secure and trusted protocols. Seeing the cryptocurrency space as a professional programmer, Olivia knows the importance of making a clean and secure DeFi protocol.
With the rate of fraudulent projects ascending contemporaneously with the rise of DeFi, Olivia knew it was crucial to have a trusted and well-secured protocol that can guide as an example for other projects to follow. Along with this idea, Olivia felt that for DeFi to reach its highest potential, there needed to be an ecosystem that protects investors and supports DeFi projects looking to bring real value to the space. With this in mind, Olivia came up with YFDAI’s signature SafeSwap and LaunchPad platforms.
Olivia has a number of qualifications and holds a bachelor’s in Computer Applications. Some of her advanced programming languages include: C, C++, JAVA, Python, Oracle.

For the past 4 years Phil has brought coverage to a multitude of different blockchain companies, each offering unique expertise and applications in a wide variety of fields.
Now that the team identities have been released this dispels the “Elephant in the room”. The fact that the team chose to become non-anon opens up many doors that would otherwise be closed. The specifics of those opportunities will be made clear in the upcoming whitepaper and future announcements.
Even though the names and faces of the founders behind the project have been revealed, please note that there are many people who are working on the YFDAI project on a contractual basis and volunteer basis who have not been included in the disclosure. There are experts and advisors in the fields of business development, economics, law, and other areas vital to any business that play a major role in the success of YFDAI and who share the vision of the founders to clean up the DeFi space and offer a safe, reliable, and secure suite of DeFi products to the public.
While the team behind a crypto project is vital, the ultimate success of any DeFi project relies on the technology, the code, and the community. YFDAI’s technology and code have been designed to be bulletproof in order to maximize the safety and security for the end user. In the not too distant future, YFDAI’s business model envisions the everyday decisions to ultimately be made by you, the community, by way of the DAO as governance is turned over to the token holders.
To ensure we are operating as securely and compliantly as possible YFDAI has been incorporated as a Technology business in Singapore:
Company Name — Tejster Technologies PTE. LTD. Registration No — 202031933C Address — 50,Raffles Place,#37–00,Singapore Land Tower, Singapore (048623)
To finalise the compliance aspect YFDAI is in the process of obtaining full Financial Services regulation by means of receiving compliance and registration in the Republic of Estonia.
This will be a two stage process with an initial Virtual Currency Exchange and E-Wallet licence currently being sought. YDFAI’s legal representatives have moved this to an advanced stage and expect this to be finalized in Q4 2020. It is at this point that the team shall resume their full job titles and the term “Volunteer” will no longer be required.
The licenses will open up a plethora of opportunities which will be fully detailed in our soon to be released whitepaper and will also provide YFDAI with a level of accreditation that will provide users with full peace of mind.
Once YFDAI secures the Financial Services accreditation listed above, YFDAI will have full insurance coverage of the project’s financial holdings and transactions, including project wallets and user funds.
Thank you for your support and we look forward to setting a new standard of self regulation that will revolutionize the DeFI arena and level the playing field for all participants while minimizing the fraud and desecration of the bad actors who have infiltrated the DeFi space.

We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.
SolutionsSyscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
Syscoin + Matic IntegrationMatic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.
Proving Performance & Cost SavingsOur POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014
The demonstration was executed using this tool. The results can be seen in the following blocks:
It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.
Cost SavingsTotal cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Superblock Validation Battles
HOWTO: Provision the Bridge for your ERC-20
HOWTO: Setup an Agent
Developer & User Diligence
Trade-offThe Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.
CostEthereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.
Z-DAGZero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).
APISyscoin-js provides tooling for all Syscoin Core RPCs including interactivity with Z-DAG.

Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana
Trade-offZ-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

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.

Ethereum cryptocurrency that comes second in terms of capitalization on the crypto market is traditionally seen as fast and profitable. However, over the last few weeks it's had a rough patch. Since early August, the network has had huge queues of transactions pending processing while fees have skyrocketed and surpassed the historical high.
The main issue though is that even fees of a few dollars per transfer don't help get rid of the“traffic jams”. The cause of this is numerous DeFi projects and a huge number of financial pyramids based on the Ethereum platform. Both generate excessive load on the network.
The situation is downright unpleasant, and our users might question whether the UMI network could face a similar challenge? We'd like to assure you it could not. The UMI network is by default protected against these problems — it cannot have “traffic jams”, fees or financial pyramids. But first things first.
How has the Ethereum network ground to a halt?
In its report dated August 4, Arcane Research that provides analysis within the field of cryptocurrency stated that over the previous week the daily size of transaction fees in the Ethereum network has surged up to a record high for over two and a half years. On August 3, the median value #%D0%9F%D1%80%D0%B8%D0%BC%D0%B5%D1%80_%D0%B8%D1%81%D0%BF%D0%BE%D0%BB%D1%8C%D0%B7%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F)of the fee amounted to $0.82, with the overall amount of transaction fees totaling $2 mln. However, it only signaled the start of real problems.
Over the next week, fees continued to grow and by August 11 the median fee value almost doubled equaling $1.57. Larry Cermak, an expert at a big analytical and news-making crypto portal The Block, wrote in his August 15 tweet that over a week the total amount of transaction fees in the Ethereum network totaled $34.5 mln, having surpassed its historical high. Meanwhile, in the Bitcoin network that is seen as too expensive the fees were almost four times lower at $9 mln.
The total fee amount paid by cryptocurrency users over a week:
Historical Growth Chart for Ethereum Fees. Source
The existing situation shows that Ethereum is actually not as fast and profitable as commonly cited. Additionally, this could happen to almost any cryptocurrency except UMI that charges no fees whatsoever. We will tell you why.
Why have these problems emerged?
There is nothing unoriginal: the Ethereum network simply can't handle an increased load. Arcane Research analysts consider that a principal cause of this situation is the constantly increasing number of the DeFi ecosystem projects built on the Ethereum blockchain. Their number is growing all the time which causes the overload of the network. As of August 12, the total amount of funds in DeFi applications reached $4.3 billion which is 19.5% higher than that in the past week. At the time of writing this article, the amount surged to $6.21 billion. You can see the current data here. What is the most unpleasant about DeFi protocols is that a lot of them are scam projects.
Which is not the worst part though. There is also another factor that significantly slows down the Ethereum network. There are a lot of pyramid-like projects that are built on the EOS platform and use smart contracts. One of them is SmartWay Forsage, which regularly overloads the network with a large number of transactions, causes traffic jams, and, consequently, leads to increased fees (keep in mind that Ethereum miners choose transactions with a higher commission). Vitalik Buterin, the co-founder of Ethereum, revealed his disapproval of the SmartWay Forsage methodology and asked them to "leave and not pollute Ethereum ecology in the future". However, the project is slow to do this — it continues to deceive users.
This is only the tip of the iceberg of scam projects which abounds on the EOS network –– they continually emerge, work for a while, then go down as scams and are replaced with new ones. This never-ending stream of "investment projects" based on the Ponzi scheme overloads the system. This is the reason why Adam Back, a pioneer of the crypto industry and founder of the technology company Blockstream, equated Ethereum with such infamous projects as Onecoin and Bitconnect. Adam Back's solid dig at Ethereum became the subject of much debate among crypto enthusiasts.
Of course, it all doesn't mean that Ethereum is a bad cryptocurrency. On the contrary, it has a lot of advantages over other coins. But all that has happened exposes Ethereum's faults which must be eliminated. The problem is that they may not be fixable. It is far from certain that the developers will be able to get rid of all the defects as the system has huge scalability problems.
The crypto community has to admit that Ethereum, like other first-generation cryptocurrencies, has issues with capacity, fees, and scalability and is gradually becoming obsolete.
2020 is the time for young innovative cryptocurrencies such as UMI.
UMI is the flagship of new-generation cryptocurrencies.
In real fact, any cryptocurrency could face it. Each cryptocurrency charges fees which typically surge when the network is overloaded or the price is going up. Everyone will remember 2017 when in line with price growth and the network's overload Bitcoin transaction fee reached a high of around $40.
But when it comes to UMI, it works the other way round. The UMI network's advantages are high capacity, no fees, and scaling possibilities. It uses the best and fastest crypto industry solutions and excludes all inefficient methods by default. Smart optimization in combination with the Proof-of-Authority technology operating on the master node basis enables almost instant payments.
At the stage of network testing, an incredibly high capacity was achieved:
The UMI network can process transactions that Ethereum processes over a year in a few days and with no fees. More details
What is more important is that less than 0.001% of the network's overall potential is used now. The UMI network has a lot of reserve capacity and can handle hundreds of thousands of times heavier load. Moreover, with scaling possibilities, UMI can keep up with the times. The UMI code ensures the safe introduction of any upgrades — the network can be easily modified and scaled with cutting edge technology solutions. In other words, traffic jams will never pose a problem for us. UMI will instantly process all transactions, with no fees. Always.
A real-time speedometer displays the number of transactions processed by the UMI network per second. Link
Additionally, unlike Ethereum and other cryptocurrencies, the UMI's staking smart contract prevents possibilities of any pyramid schemes, meaning eliminates their negative influence. Our staking is completely safe and secured against scammers. Read more about this in our article. Any UMI staking structure could work forever. In other words, you can multiply your coins at a rate of up to 40% per month for an indefinitely long period of time.
UMI doesn't inherit the disadvantages of the first-generation cryptocurrencies. This is an innovative, carefully designed network based on state-of-the-art technologies. UMI is an ambitious step toward the future. And we're making it together right now!
Sincerely yours, UMI team

How Decentralized Finance Came to BeDecentralized Finance (DeFi) can be rightfully considered a third revolution in the crypto space. If you wonder what the first two are, these are the invention of blockchain itself along with the technology’s firstborn, Bitcoin, and the inception of the smart contract technology. Just like blockchain provides the basis for smart contracts, the latter give rise to DeFi. It is often said that smart contracts are poised to revolutionize the ways both humans and organizations interact in their contractual relationships. In this sense, DeFi is the stage where these relationships are set to emerge and develop. With a bigger picture in mind, it is the world that the blockchain technology lays the foundation for, while smart contracts help to build it. Why we need DeFi, how it is possible, what makes it tick and click are the main themes of this article.
But seriously, why do we need it?As most financial services in existence today are provided by or involve third parties, for example, banks, exchanges, investment companies, insurance agencies etc, DeFi is an attempt to build an alternative environment, an ecosystem of applications offering the same set of services but now powered by public blockchain networks in a decentralized, transparent and permissionless way. By and large, the basic idea that guides DeFi is essentially the same ethos that drives innovation with crypto as such, but at an entirely different level.
Just like cryptocurrencies try to wrest the state supremacy over money from the hands of rogue governments and central banks, DeFi takes it further and aims higher. With DeFi, it is no longer a matter of creating a coin in an effort to replace fiat money, which mostly doesn’t work anyway. However, building a whole new domain of financial services available fairly and squarely to anyone, with full control over the assets but without corrupt governments and greedy intermediaries sticking around, may pan out better after all.
So, answering the question posed at the beginning of this section, we need DeFi for basically the same reasons we need cryptocurrencies. Or, put differently, if we need cryptocurrencies, an assumption that has been proved indisputable, it is inevitable as well that we will sooner or later become interested in decentralized financial services powered by these cryptocurrencies through smart contract blockchains. We can’t just create Bitcoin and say that’ll do. It is a natural development, a Maslow’s hierarchy of needs, in a sense.
How is it ever possible?As mentioned in the introduction, DeFi emerges thanks to smart contract tech and decentralized applications (or simply dApps) running them. So how does it work in practice? To better understand the idea, let’s take a closer look at a relatively simple example of a decentralized crypto-backed stablecoin which can be created through a smart contract. Stablecoins are coins whose value is pegged to a stable asset such as a commodity like gold or a fiat currency like the US dollar.
There are a few different types of stablecoins that exist in the wild. For the purpose of this exposition, we are interested in crypto-backed stablecoins. Like stablecoins collateralized by fiat, these stablecoins use cryptocurrencies as collateral. However, the key difference is that a fiat-based stablecoin is pegged to the fiat currency which is backing it up. Kinda obvious. A crypto-backed stablecoin, on the other hand, is pegged to one asset, say, the American dollar, but backed up by a completely different one, for example, Ether. Things get tricky.
A crypto-collateralized stablecoin is possible through the magic and the beauty of the smart contract governing it. If the price of such a stablecoin rises above its peg, or parity, you can create more stablecoins and sell them at a premium. If the price of the stablecoin falls below parity, you can buy stablecoins and liquidate them at a discount. If the collateral itself crashes, undercollateralized stablecoins will be liquidated with their collateral now backing up fewer stablecoins. As a result, the price always gets pushed back to parity.
And all this rather complicated stuff is done on the blockchain in a decentralized and automatic fashion with no banks or other third parties involved. Consequently, more services are easily possible too. And quite a few at that.
Okay, what decentralized financial services are available?Well, one such service we have just described above. Cryptocurrencies are infamous for being extremely volatile, and stablecoins are designed to deal with this issue. There are many stablecoins out there like Tether, TrueUSD, or Gemini Coin, but they are all based on trusting third parties. Easily one of the best known crypto-backed stablecoins is MakerDAO’s DAI, which is pegged against the US dollar with a basket of crypto-assets as collateral in a truly decentralized and trustless way, that is, a blockchain way.
Crypto-based stablecoins can be used on their own by offering a hedge against the price volatility of such popular cryptocurrencies as Ether or Bitcoin. Aside from that, they are also instrumental in other DeFi services, for example, in decentralized exchanges like IDEX or BiKi.com. With stablecoins, it becomes possible to create fiat trading pairs in addition to crypto ones in entirely decentralized, non-custodial trading environments as opposed to centralized exchanges like Bitfinex or Binance, which are vulnerable to high-profile hacks and personal data leaks.
Unlike MakerDAO, Ampleforth doesn’t strive to create a rock-solid stablecoin. Instead, it comes up with the notion of “adaptive money built on sound economics”, with its mission stretching out as far as to marry “the scarcity of Bitcoin with the elasticity of fiat”. It tries to go beyond the relatively simple concept of a stablecoin and brings forth the idea of elastic money supply that can expand and contract depending on market demands, as well as allow the creation of a valid form of collateral for DeFi based on that idea.
Obviously, DeFi is not just about stablecoins or the financial services using them. Blockchain-based borrowing and lending is another important DeFi arena. With platforms like Compound, dYdX, Dharma, you can deposit your crypto assets to either earn interest on them or use these assets as collateral for borrowing. Smart contracts automatically match borrowers and lenders, offering dynamic interest rates based on supply and demand. And with tools like LoanScan, you can also easily shop around for the best interest rates on the block.
These examples are far from exhaustive, of course, as the space is rapidly expanding and evolving. However, there are some fundamental issues that put grit into the wheels of the DeFi war machine.
So where’s the catch?There are many advantages of DeFi, but to be of any practical use, it needs up-to-date information that would be reliable and authentic. Smart contracts that DeFi is based on are hopelessly on-chain, but the data they need for processing is mostly off-chain. Without a bridge to close this gap between a smart contract and its source of external information, smart contracts are entrapped in closed-off dungeons of their blockchains. To be sure, no crypto-based stablecoin is going to work correctly without a real-time price feed for the assets taken as its collateral and used for maintaining the peg.
To get around this roadblock, a concept of blockchain oracles has been suggested. But as the chain cannot be stronger than its weakest link, blockchain oracles seem to be that weak link in the field of DeFi and beyond as obtaining information in a verifiable way can be an intimidating task. What approaches dApps are taking to procure and verify sources of truth in the external world is the topic of our upcoming article about blockchain oracles. Stay with us and stay tuned!

Instead, the future of consumer finance belongs to those who are deeply familiar with blockchain tech & decentralized protocols, build on it as the foundation, and know how to take it to the world. Like Genesis Block.
Today we begin our journey down the crypto rabbit hole. This post will be an important introduction for those still learning about Bitcoin, Ethereum, or DeFi (Decentralized Finance). This post (and the next few) will go into greater detail about how this technology gives Genesis Block an edge, a superpower, and an unfair advantage. Let’s dive in…
Bitcoin: The First CryptocurrencyThere are plenty of online resources to learn about Bitcoin (Coinbase, Binance, Gemini, Naval, Alex Gladstein, Marc Andreessen, Chris Dixon). I don’t wanna spend a lot of time on that here, but let’s do a quick overview for those still getting ramped up.
Cryptocurrency is the most popular use-case of blockchain technology today. And Bitcoin was the first cryptocurrency to be invented.
Bitcoin is the most decentralized of all crypto assets today — no government, company, or third party can control or censor it.Bitcoin has two primary features (as do most other cryptocurrencies):
The fact that there are so few things one can do with Bitcoin is one of its greatest strengths.Its design is simple, elegant, and focused. It has been 10+ years since Satoshi’s white paper and no one has been able to crack or hack the Bitcoin network. With a market cap of $170B, there is plenty of incentive to try.
Public AwarenessA few negative moments in Bitcoin’s history include the collapse of Mt. Gox — which resulted in hundreds of millions of customer funds being stolen — as well as Bitcoin’s role in dark markets like Silk Road — where Bitcoin arguably found its initial userbase.
However, like most breakthrough technology, Bitcoin is neither good nor bad. It’s neutral. People can use it for good or they can use it for evil. Thankfully, it’s being used less and less for illicit activity. Criminals are starting to understand that transactions on a blockchain are public and traceable — it’s exactly the type of system they usually try to avoid. And it’s true, at this point “a lot more” crimes are actually committed with fiat than crypto.
As a result, the perception of bitcoin and cryptocurrency has been changing over the years to a more positive light.
Bitcoin has even started to enter the world of media & entertainment. It’s been mentioned in Hollywood films like Spiderman: Into the Spider-Verse and in songs from major artists like Eminem. It’s been mentioned in countless TV shows like Billions, The Simpsons, Big Bang Theory, Gray’s Anatomy, Family Guy, and more.
As covid19 has ravaged economies and central banks have been printing money, Bitcoin has caught the attention of many legendary Wall Street investors like Paul Tudor Jones, saying that Bitcoin is a great bet against inflation (reminding him of Gold in the 1970s).
Cash App already lets their 25M users buy Bitcoin. It’s rumored that PayPal and Venmo will soon let their 325M users start buying Bitcoin. Bitcoin is by far the most dominant cryptocurrency and is showing no signs of slowing down. For more than a decade it has delivered on its core use-cases — being able to send or store value.
At this point, Bitcoin has very much entered the zeitgeist of modern pop culture — at least in the West.https://preview.redd.it/dnuwbw8mfu951.png?width=800&format=png&auto=webp&s=6f1f135e3effee4574b5167901b80ced2c972bda
Ethereum: Programmable MoneyWhen Ethereum launched in 2015, it opened up a world of new possibilities and use-cases for crypto. With Ethereum Smart Contracts (i.e. applications), this exciting new digital money (cryptocurrency) became a lot less dumb. Developers could now build applications that go beyond the simple use-cases of “send value” & “store value.” They could program cryptocurrency to have rules, behavior, and logic to respond to different inputs. And always enforced by code. Additional reading on Ethereum from Linda Xie or Vitalik Buterin.
Because these applications are built on blockchain technology (Ethereum), they preserve many of the same characteristics as Bitcoin: no one can stop, censor or shut down these apps because they are decentralized.One of the first major use-cases on Ethereum was the ability to mint and create your own token, your own cryptocurrency. Many companies used this as a way to fundraise from the public. This led to the 2017 ICO bubble (Initial Coin Offerings). Some tokens — and the apps/networks they powered — were fascinating and innovative. Most tokens were pointless. And many tokens were outright scams. Additional token reading from Fred Ehrsam, Balaji, and Naval.
Digital Gold RushJust as tokens grew in popularity in 2017–2018, so did online marketplaces where these tokens could be bought, sold, and traded. This was a fledgling asset class — the merchants selling picks, axes, and shovels were finally starting to emerge.
I had a front-row seat — both as an investor and token creator. This was the Wild West with all the frontier drama & scandal that you’d expect.Binance — now the world’s largest crypto exchange —was launched during this time. They along with many others (especially from Asia) made it really easy for speculators, traders, and degenerate gamblers to participate in these markets. Similar to other financial markets, the goal was straightforward: buy low and sell high.
That period left an embarrassing stain on our industry that we’ve still been trying to recover from. It was a period rampant with market manipulation, pump-and-dumps, and scams. To some extent, the crypto industry still suffers from that today, but it’s nothing compared to what it was then.
While the potential of getting filthy rich brought a lot of fly-by-nighters and charlatans into the industry, it also brought a lot of innovators, entrepreneurs, and builders.The launch and growth of Ethereum has been an incredible technological breakthrough. As with past tech breakthroughs, it has led to a wave of innovation, experimentation, and development. The creativity around tokens, smart contracts, and decentralized applications has been fascinating to witness. Now a few years later, the fruits of those labors are starting to be realized.
DeFi: Decentralized FinanceSo as a reminder, tokens are cryptocurrencies. Cryptocurrencies can carry value. And value is a lot like money. Because tokens are natively integrated with Ethereum, it’s been natural for developers to build applications related to financial services — things like lending, borrowing, saving, investing, payments, and insurance. In the last few years, there has been a groundswell of developer momentum building in this area of financial protocols. This segment of the industry is known as DeFi (Decentralized Finance).
In Q2 of 2020, 97% of all Ethereum activity was DeFi-related. Total DeFi transaction volume has reached $11.5B. The current value locked inside DeFi protocols is approaching $2 Billion (double from a month ago). DeFi’s meteoric growth cannot be ignored.
Most of that growth can be attributed to exciting protocols like Compound, Maker, Synthetix, Balancer, Aave, dYdX, and Uniswap. These DeFi protocols and the financial services they offer are quickly becoming some of the most popular use-cases for blockchain technology today.
This impressive growth in DeFi certainly hasn’t come without growing pains. Unlike with Bitcoin, there are near-infinite applications one can develop on Ethereum. Sometimes bugs (or typos) can slip through code reviews, testing, and audits — resulting in loss of funds.
Our next post will go much deeper on DeFi.
Wrap UpI know that for the hardcore crypto people, what we covered today is nothing new. But for those who are still getting up to speed, welcome! I hope this was helpful and that it fuels your interest to learn more.
Until you understand the basics of this technology, you won’t be able to fully appreciate the impact that it has on our new digital bank, Genesis Block. You won’t be able to understand the implications, how it relates, or how it helps.
After today’s post, some of you probably have a lot more questions. What are specific examples or use-cases of DeFi? Why does it need to be on a blockchain? What benefits does it bring to Genesis Block and our users?
In upcoming posts, we answer these questions. Today’s post was just Level 1. It set the foundation for where we’re headed next: even deeper down the crypto rabbit hole.

1. What is Bitcoin (BTC)?
2. Bitcoin’s core featuresFor a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.
Unspent Transaction Output (UTXO) modelA 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 consensusIn 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.
Block productionThe 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 difficultyBlock 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:
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 NetworkLightning 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 proposalElliptic 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 distributionThe 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.
