摘　　要：针对常规农产品追溯过程中存在的数据可信度低、关联追溯难等问题,以联盟链为基础,设计构建了一套适用于农产品的追溯系统。通过节点权限管理、数据加密上链、数据存储、基于节点关联度的哈希匹配检索等模块,能够在整个供应链流程中实现真实可信、全面完整、安全高效的多级深度追溯,有效提高了农产品追溯信息的可信度、深度和广度,具有的广泛的适用范围和较好的应用前景。Aiming at the problems of low reliability and difficult correlating in the process of conventional agricultural products traceability, a set of traceability system suitable for agricultural products was designed and constructed based on the consortium blockchain. Through functional modules such as node authority management, data encryption and chaining, data storage, hash matching retrieval module based on node association degree, it can achieve real, reliable, comprehensive, safe and efficient multi-level in-depth traceability in the whole supply chain process. It has significantly improved the reliability, depth and breadth of agricultural product traceability information, and has wide scope of application and good prospects.
