As the world¡¯s first application built on an EOS ecosphere, OracleChain needs to meet the demands of the Oracle (oracle machine) ecosystem by efficiently linking blockchain technology services with various real-life scenarios, thereby delving into this immense multibillion dollar valuation market. 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. OracleChain will nurture and serve those blockchain applications that change the real world. Our mission is to ¡°Link Data Link World,¡± with the aim of becoming the infrastructure linking the real world with the blockchain world. By achieving intrachain and extra-chain data connectivities, we aspire to create a service provisioning platform that can most efficiently gain access to extra-chain data in the future blockchain world.
