摘要

农产品交易的数据可信度跟踪受整个供应链中各个组织的影响。对于传统的集中式产品交易管理,数据只存储在供应链中的一个组织中,使得交易数据管理不透明,不可信。然而,区块链通过哈希函数将交易信息块连接成一个防篡改的分布式链账本,可以帮助解决这个问题。但区块链的数据访问性能仍有待提高。本研究以Hyperledger Fabric作为农产品去中心化追溯系统的底层技术,通过基于redis的数据结构化方法提高系统性能,设计并实现了一个农产品从生产、加工、包装、物流到销售的完整链条追溯系统。研究方案不仅介绍了该系统的设计方案和技术体系结构,还对系统在单节点和多节点服务器环境下的性能进行了评估。实验结果表明,集成Hyperledger Fabric和Redis的程序的数据访问速度比不使用Redis的程序至少快4倍,特别是对于多节点服务器,性能提升超过20倍。因此,本设计方案可以为提高农产品信用追溯系统的系统性能提供一种可行的方法。

Design and Evaluation of a High-performance Support System for Credibility Tracing of Agricultural Products
The data credibility tracing for agricultural product transactions is affected by all organizations in the entire supply chain. For traditional centralized product transaction management, the data are only stored in one organization in the supply chain, making transaction data management non-transparent and not credible. However, blockchain connects transaction information blocks into a tamper-proof and distributed chain ledger by Hash Function, which can help solve the problem. But the data access performance in blockchain still needs improvement. With Hyperledger Fabric as the underlying technology of the decentralized tracing system for agricultural products, and through improving system performance by Redis-based data structuring method, this study designed and implemented a complete chain tracing system from production, processing, package and logistics to sales of agricultural products. The study program not only introduced the design program and technological architecture of this system, but also evaluated the system performance under single-node and multi-node server environments. The experiment results show that the program integrating Hyperledger Fabric and Redis has a data access speed at least four times faster than that without Redis, especially for multi-node server, in which the performance improvement is over 20 times. Therefore, this design program can offer a feasible approach for improving system performance of the credibility tracing system of agricultural products.
