基于区块链的河豚供应链可信溯源优化研究

针对河豚供应链环节复杂、监管要求高以及溯源系统信息传递繁杂、数据查询效率低的问题，以提高河豚溯源查询效率和安全性为目的，建立了基于区块链技术的河豚供应链溯源优化模型，并搭建相应系统。首先，对河豚供应链业务供应链信息进行分析，整理并提取供应链各业务环节溯源码信息和产品信息；然后，基于区块链技术建立河豚供应链可信溯源优化模型架构，设计多链的存储模式和快速查询流程并制定相应的智能合约；最后，基于Hyperledger Fabric实现了一种河豚供应链信息溯源系统，并使用Caliper性能测试工具测试。结果表明，在数据记录条数大于1000条后，本文模型查询效率高于传统单链模型，在10000条数据记录上链后，本文模型较传统单链模型查询效率提高约92.9%。以江苏省某河豚企业为例，实现河豚供应链信息安全传递和快速溯源。所提出的模型可以应用到河豚行业从而提高溯源效率和安全性，为河豚行业提供一个防篡改、查询效率高的模型。

Trusted Traceability Optimization of Pufferfish Supply Chain Based on Blockchain

In view of the complex links of the pufferfish supply chain, high regulatory requirements, complicated information transmission in the traceability system, and low data query efficiency, in order to improve the efficiency and security of pufferfish traceability query, a type of pufferfish supply chain traceability optimization model based on blockchain technology was established, and a corresponding system was built. Firstly, the supply chain information of the pufferfish supply chain business was analyzed, the traceability source information and product information of each business link of the supply chain was sorted out and extracted;and then based on the blockchain technology, the trusted traceability optimization model architecture of the pufferfish supply chain was established, and a multi-chain storage mode and fast query process and formulate corresponding smart contracts were designed;finally, a pufferfish supply chain information traceability system was implemented based on Hyperledger Fabric, and tested by using the Caliper performance test tool. The results showed that when the number of data records was greater than 1000, the query efficiency of the model would be higher than that of the traditional single-chain model. After 10000 data records were uploaded to the chain, the query efficiency of this model was about 92.9% higher than that of the traditional single-chain model. Taking a pufferfish enterprise in Jiangsu Province as an example, the information security transmission and rapid traceability of the pufferfish supply chain were realized. The proposed model can be applied to the pufferfish industry to improve the traceability efficiency and security, and it can provide a tamper-proof and high query efficiency model for the pufferfish industry.
