Chainlink

What is Chainlink?

Chainlink is a decentralized oracle network designed to connect smart contracts with real world data. In other words, Chainlink sends information from off-blockchain sources to blockchain-based smart contracts via so-called oracles. In case you’re not familiar with the concept, oracles collect data feeds and transfer it to the blockchain. Chainlink, in an essence, combines such oracles, fuels the network and improves smart contract interconnectivity.
