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.
The Cosmos network consists of many independent, parallel blockchains, called zones, each powered by classical Byzantine fault-tolerant (BFT) consensus protocols like Tendermint (already used by platforms like ErisDB). Some zones act as hubs with respect to other zones, allowing many zones to interoperate through a shared hub. The architecture is a more general application of the Bitcoin sidechains concept, using classic BFT and Proof-of-Stake algorithms, instead of Proof-of-Work.Cosmos can interoperate with multiple other applications and cryptocurrencies, something other blockchains can’t do well. By creating a new zone, you can plug any blockchain system into the Cosmos hub and pass tokens back and forth between those zones, without the need for an intermediary. While the Cosmos Hub is a multi-asset distributed ledger, there is a special native token called the atom. Atoms have three use cases: as a spam-prevention mechanism, as staking tokens, and as a voting mechanism in governance. As a spam prevention mechanism, Atoms are used to pay fees. The fee may be proportional to the amount of computation required by the transaction, similar to Ethereum’s concept of “gas”. Fee distribution is done in-protocol and a protocol specification is described here. As staking tokens, Atoms can be “bonded” in order to earn block rewards. The economic security of the Cosmos Hub is a function of the amount of Atoms staked. The more Atoms that are collateralized, the more “skin” there is at stake and the higher the cost of attacking the network. Thus, the more Atoms there are bonded, the greater the economic security of the network. Atom holders may govern the Cosmos Hub by voting on proposals with their staked Atoms.
