Enhanced Multiset Consensus Protocol Based on PBFT for Logistics Information Traceability

In the recent years, global logistics industry has greatly driven development of world economy. At same time, a large amount data information is generated. Due to frequent occurrence leakage and forgery, it necessary find solutions that can accurately trace ensure security authenticity information. The birth blockchain technology transformed from quantitative change qualitative change. technical characteristics technology, such as distributed storage ideas, decentralization, immutability, complex encryption consensus algorithm, endow with wide range application prospects in industry. This paper proposes an enhanced multiset algorithm based on PBFT (practical Byzantine fault tolerance) for traceability blockchain. proposed multi-set topology structure composed multiple sets improve efficiency We capability transaction speed, avoid redundant message packets occupying bandwidth, efficiently process generated at any time. achieve efficient accurate traceability, are analyzed. aims solve problems trustworthiness, processing applications operate network efficiently. compares PBFT-related expansion regarding bandwidth occupation, delay, throughput. results show MPBFT significantly improves network.
