摘要:

生鲜奶是我国奶业发展的重要方向,溯源体系对整个生鲜奶行业的发展至关重要。时效性强、问题事后发现、受害者难以追踪、质检体系难以获得信任四大问题是生鲜奶行业区别于其他农产品行业的主要特征,传统农业领域溯源机制甚至基于区块链的农产品溯源机制无法满足生鲜奶行业的溯源要求。设计了一种面向生鲜奶供应链体系的追溯系统方案 RMChain,在满足现有区块链溯源机制的各种优点的同时,针对生鲜奶特点进行专门的优化,在用户溯源产品的同时,也便于问题奶的追踪定位和消费者赔偿,有效改善了生鲜奶行业的溯源现状。针对大文件严重影响区块链性能的问题,设计了基于数据重要性的多方存储模式,测试系统原型核心交易量性能数据表明,系统访问性能明显提升,验证了RMChain的可行性。

Abstract:

Abtract: The development of raw milk is an important direction for the development of China’s dairy industry, and a traceability system for the raw milk industry was proposed for the development of the entire industry crucially.The characteristics of the raw milk industry were analyzed and four major problems were proposed as the timeliness, the problems found after the fact, the difficulty in tracing the victims, the quality control system, such as difficulties in gaining trust, which were the main characteristics that distinguish the raw milk industry from other agricultural industries, and leaded to traceability in traditional agriculture.The mechanism or even the popular blockchain-based traceability mechanism for agricultural products could not meet the traceability requirements of the raw milk industry.Based on this finding, RMChain, a traceability system for raw milk supply chain system scheme, was designed to meet the requirements of the existing blockchain-based traceability mechanisms in the raw milk industry.In addition to the various advantages of the chain traceability mechanism, it was also optimized specifically for the characteristics of raw milk, which made it easy for users to trace the product and facilitate the traceability of the milk.The tracking and location of problem milk and consumer compensation effectively improved the traceability status of the fresh milk industry.For the problem of large files seriously affecting the performance of the blockchain, a multi-party storage model based on the importance of data was also designed.The feasibility of RMChain was verified.

Key words: RMChain, blockchain, raw milk, multi-party storage, access mechanism
