OracleChain is an EOS-based Oracle platform that provides accurate data feeds service, ensures high processing capacity, and low latency data services for blockchain applications. OCT is a utility token that serves as a currency on the OracleChain ecosystem. OracleChain will use an effective reward and penalty mechanism with the aim of stimulating data feeders to provide effective data feed service. All the data feeders, which regularly participate in the data feed, will attain a high reputation and be rewarded with OCT tokens. Conversely, irregular or fraudulent data feeders will have a low reputation and lose the OCT risk fund they deposited in the OracleChain platform.
