Kyber’s on-chain liquidity protocol allows decentralized token swaps to be integrated into any application, enabling value exchange to be performed seamlessly between all parties in the ecosystem. Tapping on the protocol, developers can build payment flows and financial apps, including instant token swap services, erc20 payments, and innovative financial dapps - helping to build a world where any token is usable anywhere. Kyber Network maintains liquidity through the dynamic reserve pool. The pool contains all of the Reserve Entities in the system. Having multiple entities in the pool prevents monopolization and keeps exchange rates competitive. When a user requests an exchange, the Kyber smart contract makes the exchange through the Reserve Entity with the best exchange rate for the user. By allowing external Reserve Entities, Kyber Network prevents centralization and opens the door to low-volume token listings. External reserves may be fine with taking on the risk of storing less popular tokens that the Kyber reserves don’t list. To prevent bad actors in the reserve pool, Kyber Network has few safeguards. The network will flag any exchange rate for special approval that’s greatly outside the norm. To protect funds in a public reserve, Kyber makes all exchanges using them available through a transparent fund management model. The Kyber team is impressive. Loi Luu, Yaron Velner, and Victor Tran are the founders behind the project. Luu previously created Oyente, the first open-source security analyzer for Ethereum contracts, and cofounded SmartPool, a decentralized mining pool project. Velner has been active in the Ethereum bug bounty program, and Tran is also a lead developer at SmartPool. The team has a well-rounded advisory board with the most notable member being Vitalik Buterin, Ethereum wunderkind. In August 2017, Kyber successfully launched their testnet beta. They plan on releasing their live product in Q1 this year in which you’ll be able to trade between Ethereum and ERC20 tokens. The project has an extensive list of partners including Request Network, Wax, and Storm. Because it’s an ERC20 token, you can store KNC in any wallet with ERC20 support. MyEtherWallet is the most popular online option. MetaMask works as well. Many investors choose to use a hardware wallet for additional security. You can’t go wrong with either the Trezor or Ledger wallet as both supports KNC.
EtherZero, abbreviated ETZ, is a hard fork on ethereum providing no-fee, high expansibility, real-time transaction or operation feedback services. Aiming to be a general-purpose smart contract platform, ETZ helps developers set up DAPPs that not limited in finance and business scope, but those more frequently used in daily life, to popularize decentralized services to more people and industries. ETZ eliminates the gas fee system from Ethereum network core and adds a Transaction Restriction Policy Protocol layer that associates the threshold, frequency, depth, etc. of initiating transactions with the account balance to combat DDOS like attacks. In particular, ETZ also draws on DASH's two-tier network architecture built with Masternodes transaction verification network and blockchain ledger layer, and its built-in community autonomous system to provide users with real-time operation feedback and high transaction concurrency, no longer need to wait for a long transaction confirmation time. ETZ picks the proven experience of Ethereum on smart contracts, removes its less scalability gas-based fee system and designs a fully accountable trading limit and security strategy against DDOS Class attacks. The final two-tier network composed of the main node and pow consensus layer laid the foundation to achieve free of charge, high concurrency, real-time transactions, independent evolution and several other features. What does no-fee mean to DApp Dev? Taking a simple Todolist DApp as an example, its decentralized implementation can be applied to the team task decomposition process, which requires all participants in the project to know the tasks of other members. Each task is a team consensus result with demand of traceability. The application involves registration of members, additions, deletions and alterations of tasks. According to Ethereum development requirements, all of these operations require gas consumption, which is clearly unreasonable for the users of the application. While in EtherZero, the transaction initiation frequency and the execution depth of smart contracts will be positively related to the balance possessed by the account. This mechanism is similar to POS, it takes into account the fair use of bandwidth and set a relatively high capital threshold required to launch a DDOS attack by malicious attackers while providing free services. This kind of limited and cost-effective free mechanism will spread the decentralized application into the scene of life.
