Chainlink is a decentralized oracle network that connects blockchains to real-world data, enabling secure and reliable smart contracts. It has a digital currency called LINK that can be used to pay for oracle services and participate in the network. Chainlink enables developers to build advanced onchain applications for finance, DeFi, and tokenized assets that are interoperable, compliant, and tamper-resistant.

Chainlink aims to be the backbone of blockchain finance, powering data delivery, cross-chain connectivity, and computation for institutional-grade products like stablecoins and derivatives.

LINK is a valuable and widely used cryptocurrency because it is trusted by major institutions and protocols, has enabled trillions in onchain value, and provides essential security and scalability for the DeFi ecosystem.
