The rapid development of technologies such as the Internet,cloud computing,the Internet of Things,and big data is driving the huge transformation of traditional supply chains.Traditional agricultural product supply chain platforms have problems such as opaque information management,transaction records that cannot be traced back,difficulty in proving evidence,and high data storage costs,which greatly hindered the development of agricultural product supply chains.Blockchain has the characteristics of immutable data,traceable transactions,transparent information,and decentralization of nodes.It can effectively solve the problems of the above-mentioned agricultural product supply chain system.Based on the research of blockchain technology and agricultural product traceability technology,this paper focuses on the consensus algorithm,data storage and traceability of agricultural product traceability platforms based on blockchain technology,and proposes a blockchain agricultural product traceability platform solution based on credit information.The main tasks and innovations in this paper are:First,analyze the problems and challenges faced by traditional supply chains in terms of information management,the development status and application of blockchain technology.Next,the mainstream consensus algorithm of the blockchain is researched,and an improved RAFT consensus algorithm combining the global trust model and the node management mechanism suitable for the blockchain agricultural product traceability platform is proposed.Simulation experiments show that the improved algorithm can not only select nodes with more stable performance to participate in consensus,but also improve the election efficiency of the leader node.At the same time,the algorithm combines the node management mechanism to improve the stability of the algorithm.Then,based on the analysis of the characteristics of the Ethereum public chain and the Fabric alliance chain,combined with the advantages of the blockchain in the process of agricultural product information storage and traceability,this paper proposes a double-chain agricultural product information traceability model.Experiments show that the double-chain framework improves the efficiency of data collection,storage,and traceability processes,ensures the security of data traceability verification,and improves the problems of high data maintenance costs in the blockchain.Finally,in the context of agricultural product supply chain information traceability background,combined with the research results of improved RAFT algorithm and dual-blockchain traceability framework,a design scheme of blockchain agricultural product traceability platform based on credit information is proposed.The blockchain traceability platform mainly includes two modules of supply chain management and product traceability,which not only enables each node of the supply chain to effectively manage agricultural product information,but also enables consumers and regulators to obtain product traceability information more quickly and comprehensively.Experiments show that the platform performs better in terms of throughput.
