Design And Study Of Multi Chain Cluster Structure In Port Supply Block Chain

The information sharing of the port service supply chain is a hot topic,but it has not been a good guarantee to participate in the data security among the sharing agencies.At present,the mainstream is using third party's way to input data to display data,no matter how reliable it is in real-time,reliability and data security.Recent reports are constantly showing security vulnerabilities,which seriously affects the right of privacy of institutions.In the current shared application services,the third party collects and controls a large number of institutional data,forming a great security risk.Therefore,in the process of sharing data services,it is essential to ensure the security and reliability of the data.Since bitcoin has been put forward,research has never stopped,especially in finance aspect.It has proved that the use of distributed and computable network public account records is very reliable.This paper expounds the shortcomings of the existing port service supply chain information sharing mode and the application and limitation based on block chain technology,and researches and establishes the multi chain interaction system structure for the expansion of block chain.In order to ensure fast data transmission between multiple organizations,the establishment of hypercube tag model(HyperD)and the improved routing algorithm to improve routing efficiency between institutions in this paper,the data chain classification and construct data chain encoding to reduce time of data chain search,the rapid positioning data to institutions by establishment data attribute inverted index.Finally,a multi chain cluster data management system in port supply chain is proposed in this paper to ensure that users can manage and control their data.The third party is only index of data address,and the specific data content is saved by users themselves.A protocol is implemented in this paper,which is different from bitcoin.Transactions in this system do not strictly follow the way of finance and finance.They are only used for index indexing,such as storing,querying and sharing data.In order to verify the feasibility of the proposed method,The experimental results of label mode hypercube routing query algorithm(MPPR)and known routing algorithms are compared and analyzed,and the coding mode is analyzed and verified.Finally,this paper gives an example of system effectiveness designed and implemented based on multi chain cluster structure,compares with traditional website sharing information mode,discusses the advantages and availability of blockchain cluster structure,and analyzes possible future extensions.
