Meat food traceability method and system based on block chain

Abstract

The invention discloses a meat food traceability method and system based on a block chain. The method comprises the following steps: generating traceability information of meat food through a main server and storing the traceability information in a block chain node; obtaining a standing book checking instruction input through the client; displaying the standing book information according to the standing book checking instruction; marking the ledger information as selected ledger information to obtain a traceability information viewing instruction; and displaying the traceability information corresponding to the selected ledger information according to the traceability information viewing instruction. According to the meat food tracing method based on the block chain, the defect that information is easily tampered in an existing meat food tracing technology can be avoided; specifically, because the blockchain node is a distributed shared account book and database, the blockchain node has the characteristics of decentralization, no tampering, traceability, collective maintenance, openness, transparency and the like, and the fairness and security of traceability information in the food traceability method are ensured.

Description

technical field [0001] The invention relates to the technical field of food traceability, in particular to a blockchain-based meat traceability method and system. Background technique [0002] At present, my country has carried out a lot of institutional research on food traceability and the application and promotion of enterprise traceability technology. Some places and some industry departments have also implemented some administrative regulations, requiring certain foods to be "traceable" and to establish file records; , Shanghai, Guangdong, Shandong, Jiangsu, Tianjin and other places have also successively established some food traceability systems for agricultural and sideline products, fruits and vegetables, livestock and poultry, and meat. [0003] It should be said that my country is almost at the same pace as foreign countries in food traceability research, but in general, there is still a considerable gap from developed countries in the actual application of trace...
