Design of food safety traceability system based on blockchain technology
基于区块链技术的食品安全追溯系统设计

摘要

食品安全是关乎民生的重要问题，而食品安全追溯系统是保障食品安全的关键手段之一。随着信息技术的发展，区块链技术以其去中心化、不可篡改等特性，为食品安全追溯系统提供了新的解决方案。本文旨在设计一个基于区块链技术的食品安全追溯系统，通过构建一个可靠的追溯平台，实现食品从生产到消费的全过程追溯。系统采用智能合约技术自动记录食品流转信息，并通过加密算法保证数据的安全性和完整性。实验结果表明，该系统能够有效提高食品追溯的准确性和效率，增强消费者对食品安全的信任。

Abstract

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.
