Chainlink
Also known as: LINK Oracle Network, Decentralized Data Provider, Chainlink Protocol
A decentralized oracle network that connects smart contracts with real-world data and external APIs.
Chainlink is a decentralized oracle protocol that allows smart contracts to securely interact with off-chain data, APIs, and traditional systems. It enables use cases such as price feeds, verifiable randomness, and event-driven automation. Chainlink nodes fetch and deliver data on-chain, often aggregated via data feeds to ensure accuracy. The native LINK token is used to pay for services, incentivize node operators, and participate in staking. Chainlink powers key DeFi applications and continues to expand with innovations like Chainlink Functions, CCIP for cross-chain messaging, and decentralized computation.
