摘要
针对部分农产品溯源系统存在溯源信息集中、信息易被篡改、信息不透明的突出问题,利用区块链去中心化、不可篡改、公开透明的特点,以传统农产品溯源系统的问题分析为前提,以构建基于区块链的农产品溯源系统模型为基础,利用数据分片实现农产品信息的分布式存储,设计智能合约使系统满足实际交易过程,构建系统架构并实现该区块链溯源系统。系统实现了农产品的可信溯源,保障了农产品质量信息的安全性和可信性。
In view of the problems existing in the traceability system of some agricultural products,such as the concentration of traceability information,the easy tampering of information and the non-transparency of information,this paper makes use of the characteristics of Blockchain decentralization,non-tampering,openness and transparency,on the premise of analyzing the problem of traditional agricultural products traceability system,on the basis of building the model of agricultural product traceability system based on Blockchain,the data fragmentation is used to realize distributed storage of agricultural product information,the intelligent contracts is designed to make the system meet the actual transaction process,the system architecture is constructed,and the Blockchain traceability system is implemented.The system realizes the credible traceability of agricultural products and guarantees the safety and credibility of agricultural product quality information.
