基于区块链的有机蔬菜认证与溯源方案研究

Research on Organic Vegetable Certification and Traceability Scheme Based on Blockchain

为了解决有机市场的有机作假和有机认证效率低下等问题,利用区块链技术的不可篡改、去信任化和分布存储等特性,提出基于区块链技术的有机蔬菜认证与溯源模型。论述有机市场存在的问题,并研究相关领域的国内外发展现状;分析有机蔬菜认证与溯源的数据基础,构建其认证与溯源系统模型,设计基于有机认证的智能合约;并与中心化系统对比,分析模型的优势;以购买假冒有机标识和数据作假2个情景为例,分析模型在解决有机作假和提高认证效率的效果。

To solve the problems in organic markets like organic fraud and inefficient certification,the organic chain certification and traceability model based on blockchain technology was proposed by using the characteristics of blockchain technology such as non-tampering,de-trusting and distributed storage.The problems in the organic market were discussed,and then development status of related fields at home and abroad was studied.After analyzing the data foundation of organic vegetable certification and traceability,the certification and traceability system model was constructed and the intelligent contract based on organic certification was designed.The system based on blockchain technology was compared with the centralized system,and two scenarios of buying counterfeit organic identification and counterfeit data were taken as examples to analyze the advantages and effect of the system based on blockchain technology.The result showed that the system could solve the problem of organic fraud well,improve the efficiency of organic certification and make traceable data more complete.
