摘要
结合区块链相关技术,针对药品行业的安全、流通管理、溯源追踪、监督等问题,提出了一种药品溯源追踪查询的参考方案及参考实现。以区块链技术解决药品行业存在的安全问题,所需要的主要工作包括:对参与各方的业务流程通过智能合约实现;对参与各方成员信息和药品数据信息的通用定义;对参与各方权限身份的区分约束等。区块链的核心价值之一在于解决信任问题。通过把可共享的数据以区块链共享账本的形式保存到区块链网络上,多方共同参与、维护及监督区块链网络生态,可以实现共享数据的不可篡改、可追溯等需求。相对于传统的中心化溯源形式,基于区块链技术的应用是对解决药品行业安全、溯源等问题的一种有益的尝试。
Aiming at the problems of safety, circulation management, traceability and supervision of drug industry, based on the block chain technology, a reference scheme and its implementation of drug traceability query are proposed. To solve the safety problems in drug industry by block chain technology, the main work include three parts: to implement the logic of business processes through block chain smart contracts, to define the drug data format and related data of all participant, and to distinguish and restrict the authority and identities of participants. The core value of block chain is to solve the problem of trust. By the shared ledger data letting multi-party participate in the maintenance and supervision, which can realize the goal of immutable data, traceability and some other requirements. Compared with the traditional centralized traceability, the application of block chain technology is a beneficial attempt to solve the safety and traceability problems of the drug industry.
