医药供应链中基于区块链的药品可追溯性研究

Research on Drug Traceability Based on Blockchain in Pharmaceutical Supply Chain

为减少药品安全和流通环节的风险,迫切需要有效的可追溯性解决方案。本文提出了一种利用以太坊区块链和智能合约有效执行商业交易的方法,利用智能合约来管理和控制供应链中参与者之间的交互和交易,交易记录存储在区块链的不可变账本中,并与分散的文件系统(IPFS)链接,从而向药品供应链生态系统提供透明度和可追溯性。

In order to reduce the risk of drug safety and circulation,an effective traceability solution is urgently needed.This paper proposes a method to effectively execute business transactions by using Ethereum blockchain and smart contract.Smart contract is used to manage and control the interaction and transaction between participants in the supply chain.Transaction records are stored in the immutable account book of the blockchain and linked with the decentralized file system(IPFs),so as to provide transparency and traceability to the pharmaceutical supply chain ecosystem.
