中文摘要:
      区块链技术是一种去中心化的共享总账系统和计算范式。作为一种核心的底层支撑技术,它与分布式经济系统有极高的契合度。基于公共服务平台的医药商业资源分布式调度模式是解决当前医药商业行业“散、小、乱、弱”局面的综合性解决方案,在聚合分散性资源和按需调度方面发挥着重要作用。针对公共服务平台当前存在的一些关键问题,提出了一种基于双链架构的医药商业资源公有区块链,重点研究了公有区块链的双链结构及其存储方式、隐私保护、资源寻租与匹配机制和共识算法等问题。研究结果表明,基于双链架构的医药商业资源公有区块链能够兼顾交易信息的开放性、安全性和企业信息的隐私性,自适应地完成资源的寻租和匹配,并大幅提高公共服务平台的公信力和系统的整体效率。
英文摘要:
      Blockchain is a decentralized shared ledger system and computational paradigm.As a core underlying support technology,it is highly compatible with the distributed economic system.The distributed scheduling model of pharmaceutical business resources based on the public service platform is a comprehensive solution to the current situation of pharmaceutical industry which is “scattered,small,disorderly and weak”,and plays an important role in integrating decentralized resource and making on-demand schedule.Aiming at some key problems in the current public service platform,this paper proposed a public blockchain of pharmaceutical business resources based on double chain architecture,and mainly studied the double-chain structure and its storage mode,privacy protection,resource rent-seeking and mat-ching mechanism,and consensus algorithm.The results show that the public blockchain of pharmaceutical business resources based on double-chain architecture can take into account the openness and security of transaction information and the privacy of enterprise information,self-adaptively complete rent-seeking and matching of resources,and greatly enhance the credibility of the public service platform and the overall efficiency of the system.
