区块链赋能食品供需网创新追溯模式

Innovative traceability model of the food supply and demand network enabled by blockchain

为探索当前多主体参与以及多供应链合作的全过程网络化食品追溯的实施路径,从多功能开放型食品供需网的角度开展食品质量追溯研究,提出了区块链赋能食品供需网的创新追溯模式。在探讨区块链与食品供需网的网络结构协同和系统功能协同机制基础上,构建了区块链赋能食品供需网的追溯模式总体框架,并以加工食品为例阐述了模式的具体运作。研究表明,区块链技术的赋能为食品供需网追溯提供了强有力的技术支持和实现手段的支撑,并且该模式更加符合当前食品复杂网络追溯的现状,极大程度上解决了目前食品追溯存在的集中化控制,信息不完整、可信度低等问题,深化多主体、多供应链合作意识,为食品追溯发展提供模式借鉴。

In order to explore the implementation path of the current whole-process networked food traceability with multi-agent participation and multi-supply chain cooperation,research on food quality traceability from the perspective of multi-functional open food supply and demand network are carried out,and an innovative traceability model of the food supply and demand network enabled by blockchain is put forward.Based on the discussion of the network structure collaboration and system function collaboration mechanism between blockchain and food supply and demand network,this study constructs an overall framework of the traceability model of food supply and demand network enabled by blockchain,and takes processed food as an example to illustrate the specific operation of the model.The results show that blockchain provide strong technical support and implementation support for the implementation of the food supply and demand network traceability system.The mode constructed in this study is more in line with the current situation of food complex network traceability,which greatly solves the problems of centralized control,incomplete information and low credibility of food traceability,deepens the awareness of multi-agent and multi supply chain cooperation,and provides a model reference for the development of food traceability.
