基于区块链的大宗商品供应链物流方案研究

Research on the logistics scheme of bulk commodity supply chain based on blockchain

大宗商品供应链物流是大宗商品物流的系统化发展方向,区块链技术有着分布式信任、不可纂改、可追溯和去中心化等特性,为解决物流全过程中存在的信息孤岛、货权难确认、货物安全难保障和信任度较低等问题提供了有效帮助。文章综述了区块链技术与供应链物流结合的现有研究与应用实例,对大宗商品供应链物流体系现状和区块链原理进行了简要叙述,进而提出“区块链加云”的大宗商品供应链物流数据信息存储方案,设计链上元数据构建方法,构建基于联盟链的大宗商品供应链物流方案框架,详细阐述了框架中各层的功能与效用,在具体描述物流场景的基础上完成仿真实验,并对所得结果进行分析,最后展望未来区块链在供应链中的进一步应用,为同类型的研究提供相关思路。

Bulk commodity supply chain logistics are the systematic development direction of bulk commodity logistics.Blockchain technology has the characteristics of distributed trust,immutability,traceability,and decentralization,which has provided effective help to solve problems such as information islands,cargo security confirmation difficulty and low trust.This paper summarizes the existing research and application examples of the combination of blockchain technology and supply chain logistics,briefly describes the status quo of the supply chain logistics system for bulk commodities and the principles of blockchain,and then proposes“blockchain plus cloud”as a bulk commodity supply chain logistics data information storage scheme,the design of a metadata construction method on the chain,the construction of the bulk commodity supply chain logistics scheme framework based on the alliance chain,elaborates the functions and utility of each layer in the framework,and completes a simulation experiment based on the specific description of the logistics scene,analyzes the obtained results,and finally looks forward to the further application of blockchain in the supply chain in the future,which provides relevant ideas for the same type of research.
