About Chainlink

By allowing access to real-world data and off-chain computing while keeping the security and reliability assurances built into blockchain technology, Chainlink enhances the functionality of smart contracts. Chainlink uses its decentralized oracle network to link smart contracts with outside data. Requests for the Chainlink API are processed 1:1 by an oracle. You can combine information from various oracles to provide a more solid and reliable response.
