Chainlink is a decentralized oracle network that securely connects blockchains to external data sources and systems. It uses a network of independent node operators to bring real-world information onchain and enable cross-chain interoperability through its Cross-Chain Interoperability Protocol (CCIP).

The platform provides critical infrastructure for decentralized finance, tokenized assets, and institutional applications by solving data, liquidity, synchronization, and compliance challenges. Its native LINK token is used for service payments and staking to secure the network, with revenue from enterprise adoption accumulating in a strategic reserve.
