Chainlink

Chainlink is the industry standard for building, accessing, and selling oracle services that power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries and offers global enterprises and leading data providers a universal gateway to all blockchains. Stakin is part of the Chainlink node operator set and runs a reliable infrastructure to provide data to the smart-contract economy.
