区块链架构下农产品溯源政府可信化监督管理优化模型

Optimization Model for Trusted Government Supervision and Management of Agricultural Product Traceability Under Blockchain Architecture

本文针对传统农产品产业链溯源效率低下、可信度较低、溯源系统数据易篡改等系列问题,参考农产品产业链溯源标准,结合区块链的联盟链,提出了基于“区块链+PBFT机制”的农产品大数据安全管理模型,通过BaaS云平台和物联网技术储存农产品产业链数据,同时加强隐私保护系统的构建,对农产品溯源的信息进行加密和匿名处理,实现农产品追溯与隐私保护的双重目标,在这一过程中融入政府可信化监管,由政府提供公共信用数据,从而保障消费者权益,维护市场秩序。

Aiming at a series of problems such as low traceability efficiency,low credibility and easy tampering of traceability system data in traditional agricultural product industry chain,this paper proposes a big data security management model of agricultural products based on“blockchain+PBFT mechanism”by referring to the traceability standard of agricultural product industry chain and combining with the alliance chain of blockchain.It stores the data of agricultural product industry chain through BaaS cloud platform and Internet of things technology,strengthens the construction of privacy protection system,encrypts and anonymizes the information of agricultural product traceability,realizes the dual goals of agricultural product traceability and privacy protection,and integrates government credible supervision in this process.The government provides public credit data to protect the rights and interests of consumers and maintain market order.
