基于区块链技术的食品安全溯源体系应用与研究进展

Application and research progress of food safety traceability system based on blockchain technology

我国是农业大国,食品安全问题一直以来都是人民群众和政府重点关注的问题。由于近几年食品安全问题事件频发,不仅造成了严重的信任危机,而且对人们的身体健康也造成了极大的威胁。在传统的溯源体系中,信息仍然存在不准确、不透明、不安全等问题,而区块链具有防止篡改、全过程可追溯、去中心化分布式存储等特点。将区块链技术与溯源技术相结合可以更好地解决传统溯源体系中的问题,能够实现真正意义上的溯源,切实保障供应链上全体成员以及广大人民群众的权益。本文介绍了区块链技术,梳理总结近些年基于区块链的食品安全溯源体系的研究与应用,有效地说明了构建基于区块链溯源体系时的着眼点,以期为区块链溯源体系的推广提供参考。

China is a large agricultural country, and food safety has always been a major concern of the people and the government. Due to the frequent occurrence of food safety issues in recent years, it has not only caused a serious crisis of confidence, but also posed a great threat to people’s health. In a traditional traceability system, information still has some problems, such as inaccuracy, opacity, insecurity and so on. The blockchain has the characteristics of preventing tampering, tracing the whole process, and decentralizing distributed storage. The combination of blockchain technology and traceability technology can greatly solve the problems in the traditional traceability system, it can also achieve true traceability and effectively protect the rights and interests of all members of the supply chain and the people. This paper introduced the blockchain technology, summarized the research and application of food safety traceability system based on blockchain in recent years and effectively illustrate the focus of building the traceability system based on blockchain, so as to provide reference for the promotion of the traceability system of blockchain.
