区块链驱动的稻米供应链信息监管模型研究

针对稻米供应链业务主体复杂、信息流转冗长、数据利用率低、监管覆盖性差等问题，构建了区块链驱动的稻米供应链信息监管模型，并进行系统化实现。首先，对稻米供应链信息流转特性进行分析，梳理并提炼供应链各业务环节主体及关键信息；然后，以区块链驱动构建稻米供应链信息监管模型，设计隐私数据分级加密存储模式和定制化业务逻辑监管智能合约；最后，基于Hyperledger Fabric开源框架，构建并实现稻米供应链信息监管原型系统，并以湖南省常德市某粮油企业为例，进行了应用案例实证分析。结果表明，构建的稻米供应链信息监管模型及原型系统能够解决稻米供应链数据隐私加密、安全存储及权限管理等问题，实现供应链信息互联互通和有效监管。本研究可为粮油质量安全监管提供一种可行的应用方法。

Information Supervision Modeling of Rice Supply Chain Driven by Blockchain

Aiming at the problems of complex business entities, long information flow, low data utilization and low regulatory coverage in rice supply chain, a information supervision model of rice supply chain driven by blockchain was built and implemented systematically. Firstly, the information flow characteristics of rice supply chain were analyzed, and the main body and key information of each business link in the supply chain were sorted out and refined. On this basis, the supervision model of rice supply chain information driven by blockchain was constructed, the hierarchical encryption storage mode of private data and the customized business logic supervision intelligent contract were designed. Finally, based on the Hyperledger Fabric open source framework, the rice supply chain information supervision prototype system was constructed and implemented. In addition, taking a grain and oil enterprise in Changde City of Hunan Province as an example, the application case analysis was carried out. The results showed that the rice supply chain information supervision model and prototype system constructed can solve the problems of rice supply chain data privacy encryption, secure storage and authority management, realize supply chain information interconnection and effective supervision, which can provide a way for grain and oil quality safety supervision feasible and practical application solutions.
