Research on the whole chain traceability system of dairy products based on consortium blockchain

Abstract

Dairy products are one of the indispensable foods in people's life. However, reports about the quality and safety of dairy products often appear. In this paper, a dairy product quality and safety traceability system based on consortium blockchain is proposed by using block chain technology. In addition, the traceability link in the dairy supply chain is defined, and the basic framework and traceability bar code of the traceability system are designed. The system guarantees the integrity and security of the traceability information from the technical level, and provides the dairy traceability service for the government, enterprises and consumers.
