Overview
Chainlink is the industry-standard decentralized oracle network. It allows smart contracts on any blockchain to securely interact with real-world data and off-chain computation.
How it Works
Chainlink uses a network of independent node operators who fetch data from multiple sources, aggregate it to ensure accuracy, and then deliver it to the blockchain. Node operators are incentivized with the LINK token.
