Chainlink Network (LINK) aims to provide tamper-proof inputs and outputs of data for smart contracts on any blockchain.

An individual can receive on-chain and off-chain data by connecting his smart contracts to various data sources and third-party APIs. One can also send data to parties outside of the blockchain she uses via the Chainlink Network.

Chainlink's Meta Oracle provides data aggregation and reaction services, which enables developers to further improve the functionalities of their smart contracts.

The Chainlink token (LINK) is an ERC-20 token used as the payment for all services the Chainlink Network provides.
