作为世界人口的主要食物来源,粮食质量安全对人类健康发展具有重要意义。谷物食品供应链的特点是生命周期长,大量复杂的业务数据,难以定义私人信息,难以管理和分享。为了加强多风险因素下粮粮食品供应链的信息应用处理和协调能力,基于区块链多链技术,研究了一种适用于粮食供应链的信息管理模型。首先,对粮食供应链中关键环节的信息进行分析,得到隐私数据分类。第二,构建了粮食食品供应链多链网络模型,基于这个模型,私有数据的分层加密和存储模式以及中继跨链通信模式,是设计的。此外,一个完整的共识过程,包括CPBFT,ZKP,和KZKP算法,是为多链架构下的全球信息协作共识而设计的。最后,通过性能仿真对模型进行了验证,理论分析,以及原型系统的正确性验证,安全,可扩展性,和共识效率。结果表明,该研究模型有效地降低了存储冗余,解决了传统单链研究中的数据差异共享问题,以及提供安全的数据保护机制,可靠的数据交互机制,高效的多链协同共识机制。通过尝试将区块链多链技术应用于谷物食品供应链,本研究为该领域数据信息协作共识的可信保护提供了新的研究思路。
As the main food source of the world\'s population, grain quality safety is of great significance to the healthy development of human beings. The grain food supply chain is characterized by its long life cycle, numerous and complex business data, difficulty defining private information, and difficult managing and sharing. In order to strengthen the ability of information application processing and coordination of the grain food supply chain under many risk factors, an information management model suitable for the grain food supply chain is studied based on the blockchain multi-chain technology. First, the information on key links in the grain food supply chain is analyzed to obtain privacy data classifications. Second, a multi-chain network model of the grain food supply chain is constructed, and based on this model, the hierarchical encryption and storage mode of private data as well as the relay cross-chain communication mode, are designed. In addition, a complete consensus process, including CPBFT, ZKP, and KZKP algorithms, is designed for the global information collaborative consensus under the multi-chain architecture. Finally, the model is verified through performance simulation, theory analysis, and prototype system verification in terms of its correctness, security, scalability, and consensus efficiency. The results show that this research model effectively reduces the storage redundancy and deals with problems of data differential sharing in traditional single-chain research, as well as provides a secure data protection mechanism, a credible data interaction mechanism, and an efficient multi-chain collaborative consensus mechanism. By attempting to apply blockchain multi-chain technology to the grain food supply chain, this study provides new research ideas for the trusted protection of data and information collaborative consensus in this field.
