Food safety is an important issue related to people's livelihood, and food safety traceability system is one of the key means to ensure food safety. With the development of information technology, blockchain technology provides a new solution for food safety traceability system with its decentralized and tamper-proof characteristics. This paper aims to design a food safety traceability system based on blockchain technology, and realize the whole process traceability of food from production to consumption by building a reliable traceability platform. The system uses intelligent contract technology to automatically record food circulation information, and ensures the security and integrity of data through encryption algorithm. The experimental results show that the system can effectively improve the accuracy and efficiency of food traceability and enhance consumers' trust in food safety.
