Chainlink is open-source technology that is collectively developed by a large community of developers, researchers, and users who share the goal of building Chainlink into a public good for the benefit of the entire blockchain ecosystem.
What is Chainlink?
Chainlink is a decentralized oracle network that brings off-chain data into an on-chain format, bridging the gap between the isolated blockchain and real-world data.
It aims to ensure that the external information (pricing, weather data, event outcomes) fed to smart contracts remains untampered with.
Chainlink is built on top of the Ethereum blockchain and Chainlink (LINK) is the native token of the protocol. LINK is used to pay Chainlink network operators for their services.
A brief history of Chainlink
Chainlink is a product developed by a private company called SmartContract Chainlink Ltd.
The project raised a total of $32 million during its ICO in 2017. It went live on the Ethereum mainnet 2 years later, on June 1st, 2019.
