About Chainlink

Quick take - Chainlink

Chainlink is secure, open-source blockchain middleware (referred to as an “oracle”) that provides smart contracts with any type of data or computation that they cannot inherently obtain on their native blockchain due to technical, financial, governance, or legal constraints.

Unlike blockchains, which maintain internal consistency around transaction validation, Chainlink aims to generate and deliver oracle reports to blockchains that accurately reflect the state of external events and computation. Chainlink oracles are able to generate oracle reports because the Chainlink oracle node software can read data from and write data to blockchains and APIs and perform off-chain computation.

In depth

Chainlink is a permissionless protocol and an open-source framework for the creation of decentralized oracle networks that feed reliable and high quality data into your smart contracts and provide secure off-chain computation services. FROM SYL - NEEDS EDITING

Blockchains are highly secure and reliable networks for value exchange but lack the functionality to natively fetch external data or send data to off-chain systems in a manner that retains end-to-end tamper-resistance.

Through the use of secure oracles, Chainlink extends the functionality of blockchains by connecting smart contracts to real-world data, events, payments, and off-chain computation in a highly tamper-resistant and reliable manner.
