Chainlink is a decentralized finance (DeFi) oracle that empowers Ethereum-based smart contracts with the ability to tap into real-world data and perform off-chain computations. Its suite of offerings encompasses data feeds, Verifiable Random Numbers (VRF), external API integration, and automated contract execution. The protocol’s primary objective is to ensure the autonomy of smart contract parameters by verifying their independence from external stakeholders and real-world data sources.
