As a decentralized Oracle technology platform based on the EOS platform，the autonomous Proof-of-Reputation & Deposit mechanism is adopted and used as a fundamental service for other blockchain applications. In addition to Oracle services that provide real-world data to the blockchain，Oracle services that provide cross-chain data are also offered. Given that OracleChain can accomplish the functions of several prediction market applications，such as Augur and Gnosis，it can also support smart contract businesses that require high-frequency access to outside data in certain scenarios，such as Robo-Advisor.
