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
