摘　　要：针对传统农产品溯源系统存在的溯源数据可信度较低、溯源信息有限、溯源系统可靠性低、中心化数据库易受攻击等弊端,提出了基于区块链的农产品溯源系统。在对区块链技术应用于农产品溯源领域进行了可行性分析之后,构建了基于区块链的农产品溯源系统,该系统基于采集层、数据层、网络层、共识层、合约层和应用层的体系框架,利用物联网相关技术采集农产品供应链各环节信息,同时,为避免加重区块链各节点的负载,对农产品信息进行分类存储,实施“链上链下”双存储机制,结合共识算法以及智能合约等关键技术为消费者、监管部门以及相关企业等提供农产品溯源服务。该系统实现了农产品信息的全环节采集以及全程可追溯,保障了农产品溯源信息的完整性和可靠性。A blockchain-based agricultural product traceability system is proposed to solve the shortcomings of traditional agricultural product traceability systems,such as low credibility of traceability data,limited traceability information,low reliability of traceability systems,and vulnerability of centralized databases.After conducting a feasibility analysis of the application of blockchain technology in the field of agricultural product traceability,a blockchain-based agricultural product traceability system is constructed.The system is based on a system framework of collection layer,data layer,network layer,consensus layer,contract layer and application layer,and utilizes IoT related technologies to collect information from all links of the agricultural product supply chain.At the same time,to avoid increasing the load on each node of the blockchain,agricultural product information is classified and stored,the system implements the "on chain and off chain" dual storage mechanism,and combines with consensus algorithms and smart contracts,to provide agricultural product traceability services for consumers,regulatory authorities,and related enterprises.The system realizes the full process collection and traceability of agricultural product information,ensuring the integrity and reliability of agricultural product traceability information.
