摘要
由于传统药品溯源中依赖一个中心化组织,溯源参与方众多,信息整合困难,导致了溯源结果可信度不够并且溯源信息不够完整。文章采用超级账本作为区块链中的实现方式,提出了一种基于区块链的药品溯源系统的解决方案。根据区块链作为分布式账本、数据保真的特点,针对药品的运作流程设计了区块链溯源系统。演示表明该系统对药品信息具有追溯的可行性与追溯信息的完整性,为促进药品溯源与区块链应用相结合提供参考。
Because traditional drug traceability depends on a centralized organization which has many traceability participants,information integration is difficult and makes the traceability results credibility is not enough and traceability information is not complete.This paper proposes a solution for a drug traceability system based on blockchain,using Hyperledger Fabric as the implementation method in the blockchain.A blockchain traceability system for the operation process of drugs is designed according to the characteristics of the blockchain as a distributed ledger and the original data.The final demonstration shows that this system possesses the feasibility of drug information traceability and the integrity of traceability information,which provides reference for promoting the combination of drug traceability and blockchain application.
