Application Of Reputation-Based Blockchain Consensus Algorithm In Logistics Information Platform

In recent years,the global logistics industry has been continuously expanding,and logistics enterprises’ supply chains have been constantly expanding.The logistics industry is increasingly adopting digital technologies to optimize transportation,warehousing,and supply chain management.However,issues such as information opacity,data tampering,and information asymmetry have also emerged in the logistics system,posing challenges to supply chain management and cargo tracking.At the same time,false records and fraudulent activities in the logistics system have also led to a lack of trust between industry participants.Blockchain can establish a distributed,tamper-proof database,allowing all participants to share reliable information and data,thereby achieving more efficient,secure,and reliable logistics transportation.Therefore,this paper designs and implements a blockchain-based logistics information platform to solve the above problems.Consensus algorithm is the most important component of any blockchain-based system,which determines the performance and security of the entire system.Due to the nature of the peer-to-peer network,which is open and dynamic,nodes can join and leave the network at will,resulting in significantly increased security risks in this environment.Therefore,it is essential to have a system that can provide reputation incentives and punishments for malicious behavior by nodes.In this work,a reputation-based consensus algorithm called Proof of Reputation(PoR)is designed for the blockchain-based logistics information platform,where the nodes with the highest reputation value ultimately become part of the consensus group that determines the blockchain’s state.In this paper’s reputation-based consensus algorithm,the node’s reputation is calculated by mixing a set of standardized ratings and the corresponding reputation values provided by nodes at a given point in time,rather than simply the ratings given by other nodes directly.The node’s behavior affects its overall reputation value.It has been proven through experiments that the proposed consensus algorithm effectively shortens the time to reach consensus,improves network throughput,and ensures network security.Based on the improved reputation consensus algorithm,this paper designs and implements a blockchain-based logistics information platform,including the design of the consensus framework and overall structure.Through experimental testing,the system’s performance meets practical needs,and the efficiency of information storage and traceability in the logistics process is effectively improved.
