摘　　要：粮油质量安全关乎国家的稳定发展,但目前还存在诸多粮油质量安全问题,特别是异构系统间数据的可信互联、高效互通得不到保障。因此,本研究首先在对粮油质量安全全链条信息流转特性进行分析的基础上,构建粮油质量安全全链条架构,并对典型环节进行关键信息分类。然后基于可信区块链和可信标识构建粮油质量安全可信溯源模型,对区块数据结构、标识体系编码规则、存储方式等进行定义和重构,并提出链网连接器的概念及具体架构方案。最后,以典型粮油品种小麦为例,基于超级账本Fabric开源框架设计并研发了小麦质量安全可信溯源系统,对模型进行了系统实现验证和案例分析。结果表明,研究的模型及系统实现了粮油质量安全全链条信息互联互通,并且保证了跨链信息交互的安全与全流程可追溯性。The quality and safety of grains and oils concerns national stability and development,but there are currently many problems with the quality and safety of grains and oils,especially the fact that reliable and efficient data interconnection between heterogeneous systems cannot be guaranteed.Firstly,based on analysis of the characteristics of information flow in the grain and oil quality and safety chain,its architecture was constructed,and the key information in the typical links was classified.Then,based on the trusted blockchain and trusted identification,a trusted traceability model for the quality and safety of grains and oils was constructed,the block data structure,identification system coding rules,and storage mode were defined and reconstructed,and the concept and specific architectural scheme of chain network connector were innovatively proposed.Finally,a trusted traceability system for wheat quality and safety was developed based on the Hyperledger Fabric framework,verified and applied to case analysis.The results showed that the proposed model and system allowed information interconnection in the grain and oil quality and safety chain,and ensure the safety of cross-chain information interaction and the traceability of the whole process.
