Chainlink

Chainlink is a decentralized oracle and cross-chain interoperability network that supplies external data and services to smart contracts. Data Feeds aggregate publisher inputs, while Proof of Reserve, Automation, Functions, and the Cross-Chain Interoperability Protocol address reserves, scheduled execution, off-chain computation, and messaging between networks. Coverage should examine node and publisher incentives, aggregation methods, feed governance, contract interfaces, CCIP security, integrations, outages, upgrades, and incidents. Applications consuming Chainlink services and the assets represented by its feeds retain separate tags.
