摘　　要：针对全国毒品检验业务数据量大以及毒品检验大数据存储与共享效率效率低下的问题,提出了三链融合区块链拓扑结构,即由实验室雾节点组成一个可编辑的轻量级主链,每个雾节点敷设两个辅链:包括可编辑的现场快检区块链和可编辑的可扩展双子链,并在每个区块链中每个区块头扩展区域中引入Bloom Filter提升区块链数据查询效率,引入雾-链-云存储模式解决数据共享存储效率低下问题,减轻区块链上数据存储和高频访问的压力,构建高效毒品检验大数据平台。经仿真实验分析表明,采用三链融合区块链拓扑结构以及各类引入的区块链举措,适应了毒品检验数据共享的业务结构,并提升了数据共享存储效率和访问效率。Aiming at the problems of large amount of data of national drug inspection business and low efficiency of storage and sharing of big data of drug inspection,a three-chain fusion block chain topology was proposed.The blockchain structure consists of a primary blockchain and two secondary blockchains.The main blockchain consists of a large number of fog nodes,and it is an editable lightweight blockchain.Each fog node attach two auxiliary chains externally.One of the secondary blockchains is an editable field fast detection blockchain.Another secondary blockchain is an editable field investigation blockchain,and it is a scalable twin chain blockchain.Bloom Filter is introduced into each block header extension region in each blockchain to improve the efficiency of blockchain data query.The introduction of fog-chain-cloud storage mode solves the problem of low efficiency of shared data storage,and it can reduce the pressure of data storage and high-frequency access on blockchain.Finally,an efficient drug inspection big data platform is built.Simulation experiments show that the three-chain fusion blockchain topology and various introduced blockchain measures can adapt to the business structure of drug inspection data sharing,and improve the efficiency of data sharing storage and access.
