Chainlink (LINK) is the industry-standard oracle platform that enables smart contracts on blockchains to securely interact with real-world data, APIs, and external systems. Traditional blockchains cannot directly access external data, which limits their functionality. Chainlink solves this by using oracles—nodes that fetch, validate, and deliver off-chain information to smart contracts.
The network is decentralised, ensuring data accuracy and reducing the risk of single points of failure. Chainlink’s oracles are widely used in applications like decentralised finance (DeFi), supply chain tracking, and insurance, where reliable data inputs are critical. It brings these capital markets onchain and features a novel fee model where offchain and onchain revenue from Chainlink adoption is converted to LINK tokens and stored in a strategic Chainlink Reserve.
The native cryptocurrency, LINK, is used to pay node operators for their services and incentivise honest behaviour within the network. LINK can also be staked by participants to help secure the system and earn rewards. As a widely adopted oracle solution, Chainlink plays a key role in expanding blockchain use cases beyond simple token transactions.
