【Abstract】Food safety is related to the national economy and people's livelihood and has always been the focus of the people and the government. Blockchain technology has characteristics of being decentralized, tamper-free, and having underlying openness. It can record and trace product information, prevent data tampering, effectively enhance the transparency of product information, and provide new methods and ideas for food safety traceability. At present, research hotspots mainly focus on the design and construction of a trusted blockchain traceability system, but the provided blockchain traceability system cannot provide a way to verify the authenticity of the information. This paper studies the credibility evaluation model of the members involved in the blockchain and the on-chain data quality model and provides a method to solve the credibility of the on-chain data. Meanwhile, the effectiveness of the method is validated by a case study.
