Chainlink is a tokenized oracle network that provides price and events data collected from on-chain and real-world sources. Launched in 2017 by Sergey Nazarov, Chainlink aims to offer a solution to the “oracle problem,” or the ability to get the off-chain data needed to operate many blockchain-based smart contracts. The token incentivizes participants to provide and use this data. Chainlink does not operate its own blockchain. Instead, the token protocol is blockchain agnostic and can run on many different blockchains simultaneously.
