Chainlink is a decentralized network of nodes launched on the Ethereum blockchain that power the network through decentralized data providers called oracles. It provides real-world data from third-party sources to on-blockchain smart contracts through the oracle network. Chainlink's native ERC-20 token is rewarded to oracles who provide accurate data. With Chainlink’s help, it is now possible to use smart contracts in the traditional financial system. The project has received numerous awards and garnered status from the World Economic Forum as a Pioneer in 2020.
