Chainlink is a decentralized oracle network that enables smart contracts to securely interact with real-world data, APIs, and external systems.

Blockchains are designed to operate independently and cannot directly access external information. Chainlink solves this limitation by providing decentralized oracles that deliver reliable off-chain data to smart contracts.

The network is powered by the LINK token, which is used to pay node operators for retrieving, verifying, and delivering data to decentralized applications across multiple blockchain platforms.
