       About Chainlink (LINK)

       Chainlink (LINK) is a decentralized oracle service, which aims
       to connect smart contracts with data from the real world. Since
       blockchains cannot access data outside their network, oracles
       are needed to function as data feeds in smart contracts. Oracles
       provide external data (e.g. temperature, weather) that trigger
       smart contract executions upon the fulfillment of pre-defined
       conditions. Participants on the Chainlink network are
       incentivized (through rewards) to provide smart contracts with
       access to external data feeds. Should users desire access to
       off-chain data, they can submit a requesting contract to
       ChainLink’s network. These contracts will match the requesting
       contract with the appropriate oracles. The contracts include a
       reputation contract, an order-matching contract, and an
       aggregating contract. The aggregating contract gathers data of
       the selected oracles to find the most accurate result.
