摘　　要：随着我国粮食物流在公铁水多式联运过程中面临的挑战日益增多,信息共享和管控成为关键问题。针对传统的粮食溯源体系面临数据中心化、信息不透明、数据易伪造等问题,提出一种粮食多式联运区块链分级多链溯源模型。该模型包含一级链Ms—Raft算法、二级链R—PBFT算法和智能合约算法,一级链和二级链通过哈希锁定相互锚定,保证数据传输的可靠性。对比试验表明,分级多链模型的写入吞吐量为170 tps、读取吞吐量为280 tps、平均记账时延为0.25 s、平均写入时延为0.50 s、平均查询时间为0.41 s,与单链模型相比有更高的网络性能、共识效率和运行效率,且安全性更高,满足粮食多式联运溯源的需求。With the increasing challenges faced by China's food logistics in multimodal transportation by road,rail,and water,information sharing and control have become key issues.A graded multi-chain traceability model for food multimodal transport based on blockchain is proposed to address problems with traditional food traceability systems,such as data centralization,lack of information transparency,and data forgery.This model includes a primary chain using Ms—Raft algorithm,a secondary chain using R—PBFT algorithm,and smart contract algorithms.The primary and secondary chains are anchored to each other through hash locking to ensure the reliability of data transmission.Comparative experiments show that the multi-chain model achieves a write throughput of 170 tps and read throughput of 280 tps,with average delays of 0.25 s for accounting and 0.50 s for writing,and an average query time of 0.41 s.Compared with the single-chain model,it offers improved network performance,consensus efficiency,and operational efficiency,with enhanced security,meeting the traceability requirements for food multimodal transportation.
