General Data and Information Chainlink (LINK) is a decentralized network that provides information (oracles) to smart contracts. Founded in 2017 by Sergey Nazarov and Steve Ellis, Chainlink aims to solve the problem of off-chain information sourcing by smart contracts for their execution parameters. Smart contracts are designed to execute automatically when certain paramenters are met, however, when these parameters exist off-chain there is a reliance on sources of information (known as oracles) to provide the necessary information. Off-chain oracles tend to be centralized and with it comes a reliance on a third party to provide critical information in a trustworthy and time critical manner. ChainLink aims to break this reliance by feeding information to smart contracts via a network of decentralized oracles that work together on the Link blockchain to verify and forward critical information to these contracts. The ChainLink network allows users who have either a data feed or information carrying APIs to easily provide information to smart-contracts in exchange for the LINK token. Milestones September 2017 - ChainLink ICO. November 2018 - Town Crier (smart contracts and data privacy projects) acquired. 13th June 2019 - Partnership with Google announced Utility The Link Network provides timely and accurate information to smart contracts via a decentralized network of oracles (data feeds and APIs). This information is critical to the effective and accurate execution of smart contracts, as the information required exists off-chain and a reliable method for getting the information on chain is necessary. The LINK token serves as a payment for smart contracts that utilise the data provided by the Link Network, with oracles that provide accurate information being rewarded in proportion to their staked LINK. Significant Features Partnerships with major industry players such as SWIFT and Google Integrations by Ethereum sidechains such as Harmony, Celer and Matic. Average blocktime n/a; Total supply of 1 Billion LINK ; Oracle Consensus written into Ethereum Blockchain via threshold signatures.
