Chainlink is a decentralized oracle network that connects smart contracts with real-world data and external systems, playing a critical role in DeFi and Web3 applications.

A decentralized oracle network that provides "bridges" for smart contracts. It securely fetches real-world data (like stock prices or weather) and feeds it into the blockchain, allowing automated contracts to react to events happening outside the digital network.

Data Feed Oracle: Used to pay node operators for providing smart contracts with secure, tamper-proof access to real-world data, such as price feeds, weather info, and sports results.

Oracle Incentive: Node operators are paid in tokens to retrieve and validate real-world data for smart contracts. It uses a "reputation" system where nodes must hold tokens to prove their reliability to data consumers.
