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.
