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.
Beam Mimblewimble is a scalable, fungible, and confidential cryptocurrency based on the Mimblewimble implementation. WHY BEAM? Core features include complete control over your privacy, All transactions are private by default, No addresses or other private information are stored on the blockchain, Superior scalability due to compact blockchain size, Opt-in Auditability, Support online and offline transactions, atomic swap, hardware wallets integration. Governance model No premine, No ICO. Backed by Treasury Establishing a non-profit foundation to govern the protocol after Mainnet launch How does it work? Wallets’ owners create new transaction using secure channel either online or offline Both wallets participate in signing the transaction using Schnorr protocol Wallet sends transaction to node Each transaction contains a list of Inputs and Outputs represented by Pedersen Commitments, as well as explicit fees and kernels. Each transaction also contains non-interactive zero knowledge range proof to verify that the output transaction value is positive Transaction is verified by the node Each transaction is verified with respect to the recent blockchain state which is stored as a Merkle Tree. The root hash of the tree is recorded in block header along with a proof of work. In addition, each node periodically creates compacted history to allow ‘fast sync’ of new and existing nodes. Transaction is added to the mining pool A block is mined every minute and is sent back to the node for verification and distribution. Mined blocks containing the new transactions are sent to the known peers A valid block that is extending the longest chain is accepted as a new Tip and propagated further until full consensus is reached. Fast sync When a new node connects to the network for the first time it can request compacted history containing only system state and blockchain headers. There is no need to retrieve the entire transaction history.
