Your smart contracts connected to real world data, events and payments
Chainlink is a decentralized oracle network that aims to connect real-world data to smart contracts. It offers secure, tamper-proof inputs and outputs on every blockchain for complex smart contracts. With Chainlink, individuals can receive on-chain and off-chain data by connecting their smart contracts to various data sources and APIs. They can also use Chainlink to send data outside of the blockchain using the Chainlink Network.
With Chainlink’s Meta Oracle, developers can further improve the functionalities of their smart contracts. It does this using the provided data aggregation and reaction services from the oracle.
Chainlink uses its own token called LINK, an ERC-677 token as the payment for all services Chainlink provides to its users.
