The ChainLink Network is the first decentralized oracle network; allowing smart contracts secure access to external data, off-chain payments, and other API capabilities. ChainLink operators provide their services to smart contracts for LINK tokens. ChainLink is built by the team at 3.5 year-old company SmartContract, based in San Francisco, which does custom enterprise smart contract rollouts. So far SmartContract’s biggest client has been inter-bank transaction network SWIFT, which has 11,000 banks in its network.
