基于Hyperledger Fabric的区块链农产品溯源方案

A Scheme about Agricultural Produce Traceability Using Blockchain Based on Hy-perledger Fabric

摘要: 传统的农产品溯源系统的实现依赖于中心化存储，数据不透明，易被篡改。而现有的区块链溯源系统与农产品溯源的需求结合不紧密，且对大规模溯源信息的管理和查询较为低效。提出并实现一种基于Hyperledger Fabric构架的农产品联盟区块链溯源方案，在保证溯源可信的基础上，针对农产品溯源流程和联盟区块链技术的特点，设计系统架构及链操作方法，提升大规模数据上链和查询的速度，使其满足农产品溯源应用的需求。结果表明，基于该方案实现的区块链溯源系统优化了大规模溯源信息的存储与查询流程，覆盖农产品的全生命周期，具有一定的实用性。

Abstract: The implementation of the current agricultural produce traceability system based on centralized storage shows many disadvantages. Its data is not transparent, easy been tampered with, and incredible. The existing blockchain traceability system is not closely combined with the requirements of agricultural produce traceability, and the management and query of large-scale traceability data are inefficient. Therefore, this paper proposes a consortium blockchain scheme based on the Hyperledger Fabric framework which ensures traceability credible and promotes transaction efficiency by designing the system architecture and the chain operation method in the view of the agricultural produce traceability and consortium blockchain to meet the needs of agricultural produce traceability. The results show that the blockchain traceability system based on our scheme optimizes the transaction process of large-scale traceability data, covering the whole life cycle of agricultural products, and has certain practicability.
