Design and Implementation of Beef Product Quality and Safety Traceability System Based on Blockchain Technology

Abstract

With the progress of society, the society pays more attention to food safety, and the demands of consumers and regulatory authorities also increase. The original beef traceability system seems to be unable to meet the demand because of the complicated traceability links, difficult traceability and easy tampering of node data. In order to better meet the needs of the public, a beef product traceability system based on blockchain is designed. The core board is mainly based on consensus algorithm to package data on the chain and update the latest block height, and then use hash function to encrypt the information data on the chain, and then use the node-association-based hash matching retrieval and verification method to provide feedback verification of the obtained results, thus realizing the real and comprehensive, efficient and safe multi-level deep traceability of the whole beef cattle supply chain system, effectively guaranteeing the depth, breadth and credibility of traceability information. It effectively guarantees the depth, breadth and credibility of traceability information, and has good practical application prospects compared with traditional traceability systems.
