Chainlink #18

Chainlink is a decentralized oracle network that enables smart contracts on any blockchain to securely interface with real-world data and services. Its native cryptocurrency, LINK, is an ERC-20 token used to pay node operators for retrieving data for smart contracts and provide collateral to ensure data integrity. Chainlink's infrastructure enhances smart contracts by allowing them to access off-chain resources, serving as a critical component in many decentralized finance (DeFi) applications. Notably, Chainlink allows any participant to become a node operator, earning revenue for running data infrastructure, making it key to democratizing access to information.
