With the rapid development of the food industry,food safety problems have become increasingly prominent,and traceability has become an important means to ensure food safety.However,the traditional food safety traceability method has some problems,such as asymmetric information and easy data tampering,which can not meet the needs of modern food industry.Block-chain technology,with its decentralized,immutable and other characteristics,provides a new solution for food safety traceability,and hybrid encryption technology is adopted in the data transmission process.This paper aims to explore the food safety traceability scheme based on blockchain,analyze its advantages and verify it with simulation experiments,in order to provide effective support for food safety traceability.
