基于区块链的药品供应链溯源系统设计与实现

Design and Implementation of Drug Supply Chain Traceability System Based on Blockchain

药品质量安全关乎民生健康,当前药品供应链收集数据多采用云技术等中心化的存储模式,无法确保数据的安全性,且面临着溯源困难、信息共享效率低、追责困难等问题。区块链去中心化、可追溯、防篡改等特性可与药品供应链相契合,整合各参与方信息,弥补药品供应链溯源体系存在的不足。基于此,设计了一种基于区块链药品供应链溯源系统,采用Ethereum作为溯源技术方案实现平台,系统中引入药品供应链上主要参与节点,设计溯源查询、对公转账等功能模块,同时为监管部门和消费者提供溯源接口,方便药品的实时召回和投诉。最后介绍各功能模块,并对模块测试结果进行展示,研究结果也有利于丰富区块链应用于药品溯源领域的研究。

Drug quality and safety is related to people’s health. Currently, drug supply chain data collection mostly adopts cloud technology and other centralized storage modes,which cannot ensure data security and is confronted with problems such as difficulty in traceability, low efficiency of information sharing and difficulty in accountability. Block chain’s decentralized, traceable, tamper-proof and other features can be integrated with the pharmaceutical supply chain to integrate the information of all participants and make up for the shortcomings of the pharmaceutical supply chain traceability system.Based on this, we design a drug supply chain based on block chain traceability system, using Ethereum as traceability technology scheme implementation platform, the system introduced in the main participating nodes on the pharmaceutical supply chain, design traceability queries, contrary to transfer, such as function modules, at the same time provide traceability for regulators and consumers interface, convenient real-time recall and complaints of the drug. Finally, each functional module is introduced and the test results of the module are presented.The research results are also conducive to enrich the research on the application of block chain in the field of drug traceability.
