Chainlink (Link) is a decentralized digital currency platform and oracle network designed to allow a smart contract to achieve its maximum efficiency. Most crypto contracts can only function on a particular blockchain but are unable to communicate with other data feeds from external sources. Therefore, they can only perform with the data within the specific platform.
