The current agricultural products supply chain traceability system has problems such as low data storage capacity, centralized management, poor scalability, and the inability to guarantee the privacy information of participants. This paper used the Hyperledger Fabric v2 . 0 platform to design an agricultural products supply chain traceability system based on master- slave federated chain structure to solve the above problems. This system used the constructed master-slave federated chain model to store information of the supply chain, and used the multi-channel design scheme of the federated chain to ensure the security of the private information of each participating subject in the supply chain. This system deployed IoT devices in each supply chain participant to collect, process and upload information to ensure that the information stored in the supply chain wasn' t tampered with, safe and reliable. At the same time, this paper designed a smart contract between the master chain and the slave chain to determine the rationality of the information uploaded by each participant following the " National Food Safety Standard" to ensure the quality of the food at the source. In addition, it designed aclustered transmission method to upload the large amount of data generated by IoT devices in the farm with low energy consumption. The experimental results show that the system builds the agricultural products supply chain with low latency and returns the information for consumer queries in a shorter time. Meanwhile, the clustered transmission method can significantly reduce the energy consumption generated by uploading data from IoT devices. The designed agricultural products supply chain traceability system realizes the openness and transparency of the agricultural products supply chain, improves the efficiency of supply chain information traceability, and in creases consumer s' food safety trust.

针对目前农产品供应链追溯系统存在的数据存储容量低、管理中心化、可扩展性差、参与主体隐私信息 得不到保证等问题,使用 Hyper ledge Fabric v2.0平台设计了基于主从联盟链结构的农产品供应链追溯系统。该 系统基于已构建的主从联盟链模型存储供应链的信息,利用联盟链的多通道设计方案保证了供应链各参与主体 隐私信息的安全性。通过在供应链的各参与主体中部署物联网设备进行信息的采集、处理和上传,保证了供应 链存储的信息无人为窜改且安全可信。同时,基于《食品安全国家标准》设计了主从链间的智能合约,用于判断 各参与主体上传信息的合理性,以实现从源头保证食品的安全质量。此外,设计了分簇集群传输方法以较低的 能耗上传农场中物联网设备产生的大量数据。实验结果表明,该系统可以以较低的时延构建农产品供应链,并 且可以在较短时间内返回消费者查询的信息。另外,使用分簇集群传输方法可以明显降低物联网设备传输数据 产生的能耗。所设计的农产品供应链追溯系统最终实现了农产品供应链的公开透明,提高了供应链信息溯源效 率,增加了消费者对食品安全的信任度。 [ABSTRACT FROM AUTHOR]
