| Abstract: | Being widely used in modern supply chain systems,blockchain-based traceability systems usually choose consortium blockchain for construction.However,such blockchain-based traceability systems usually have multiple stakeholders and highly heterogeneous consensus networks,leading to a reduction in their performance and security. This paper analyzes the consensus process of blockchain,and constructs a reputation model as well as a system model that simulates blockchain-based traceability to eliminate Byzantine faulty nodes.Then the paper proposes the design of a consensus mechanism that includes the representative selection stage and the representative consensus stage,and on this basis proposes a reputation-based two-stage consensus strategy named RTsBFT for blockchain-based traceability systems.Experimental results show that compared with the CSBFT and PBFT protocols,RTsBFT can improve the system throughput,and reduce the delay as well as failure rate of nodes with the same configuration,improving the performance and security of the traceability systems in the consortium blockchain scenarios. |
