Chainlink

About Chainlink

Chainlink (LINK) is a decentralized oracle network that connects smart contracts to real-world data, solving the fundamental problem of blockchains being unable to access external information on their own. A network of independent nodes fetches, validates, and delivers verified data to smart contracts on any blockchain. Chainlink offers services including price data feeds, cross-chain messaging via CCIP, automation, and proof of reserve verification. It has become critical infrastructure for DeFi and institutional finance, with partnerships spanning Swift, Mastercard, and J.P. Morgan. LINK is used to pay node operators and secure the network through staking.
