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 bitcoin network is a peer-to-peer payment network that operates on a cryptographic protocol. Users send and receive bitcoins, the units of currency, by broadcasting digitally signed messages to the network using bitcoin cryptocurrency wallet software. Transactions are recorded into a distributed, replicated public database known as the blockchain, with consensus achieved by a proof-of-work system called mining. Satoshi Nakamoto, the designer of bitcoin claimed that design and coding of bitcoin began in 2007. The project was released in 2009 as open source software. The network requires the minimal structure to share transactions. An ad hoc decentralized network of volunteers is sufficient. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will. Upon reconnection, a node downloads and verifies new blocks from other nodes to complete its local copy of the blockchain. A bitcoin is defined by a sequence of digitally signed transactions that began with the bitcoin's creation, as a block reward. The owner of a bitcoin transfers it by digitally signing it over to the next owner using a bitcoin transaction, much like endorsing a traditional bank check. A payee can examine each previous transaction to verify the chain of ownership. Unlike traditional check endorsements, bitcoin transactions are irreversible, which eliminates the risk of chargeback fraud. Although it is possible to handle bitcoins individually, it would be unwieldy to require a separate transaction for every bitcoin in a transaction. Transactions are therefore allowed to contain multiple inputs and outputs, allowing bitcoins to be split and combined. Common transactions will have either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and one or two outputs: one for the payment, and one returning the change, if any, to the sender. Any difference between the total input and output amounts of a transaction goes to miners as a transaction fee. In 2013, Mark Gimein estimated electricity consumption to be about 40.9 megawatts (982 megawatt-hours a day). In 2014, Hass McCook estimated 80.7 megawatts (80,666 kW). As of 2015, The Economist estimated that even if all miners used modern facilities, the combined electricity consumption would be 166.7 megawatts (1.46 terawatt-hours per year). To lower the costs, bitcoin miners have set up in places like Iceland where geothermal energy is cheap and cooling Arctic air is free. Chinese bitcoin miners are known to use hydroelectric power in Tibet to reduce electricity costs. Various potential attacks on the bitcoin network and its use as a payment system, real or theoretical, have been considered. The bitcoin protocol includes several features that protect it against some of those attacks, such as unauthorized spending, double spending, forging bitcoins, and tampering with the blockchain. Other attacks, such as theft of private keys, require due care by users.
