Abstract
Business processes often involve operational processes, contracts, and regulations. The modeling of such processes must address regulation monitoring and enforcement and maintain a reliable history of data for evidence. This study proposes modeling business processes as chaincode (CC) on permissioned blockchains (BCs). The challenges encountered by the proposed approach are state synchronizations among distributed nodes (called authnodes)and realtime requirements. This study separates CC executions from the state management of multiple BCs and demonstrates the validity of the proposed approach with a payment authorization system at a Chinese bank.
