Smart-Contract Execution with Concurrent Block Building

Abstract

Business processes are often related to operational processes, contracts, and regulations. Modeling such processes needs to address regulation monitoring and enforcement, and maintain a reliable history of data for evidence. This paper proposes modeling business processes as smart contracts (SCs) on permissioned blockchains (BCs). The challenges with the proposed approach are state synchronizations among distributed nodes (called authnodes), and real-time requirements. This paper separates the executions of SCs from the state managements on multi-BCs, and proposes a pipeline model to verify and create blocks in parallel.
