The Performance Optimization Scheme Of Blockchain-based Industrial Internet Identification Resolution System

With the widely used of 5G mobile technology and global digital industry upgrading,the transfer from consumption to production of Internet is speeding up significantly,as a combination of new information communication technology and modern industrial,Industrial Internet is an important approach to realize digitalization,networking and intelligent.Identification and Resolution is a vital part of the Industrial Internet,but traditional identity system could have disadvantages like one-point resolution and deferent standards.To solve the problems of traditional identity system,such as one-point breakdown,high load and central control power,this paper designed a half-central network architecture with two layers based on distributed hash table and blockchain technology,then developed a new distributed Industrial Internet Identification and Resolution system,which can realize decentralization of huge amounts of industrial data,and provide safe,reliable,rapid,efficient,continuous,concurrent-supported resolution services,as well as authentication,access control and data certification services.What's more,this system solved the contradiction between effective supervision,centralized control and decentralized autonomous,load balancing.In order to improve the system performance,and solve the problems of limited computing,storage,network resource and expandability on traditional blockchain,this paper also designed a Lightweight Hybrid Blockchain model with high performance based on weighted model,hybrid consensus and consistent hashing,realized efficient and reliable verification and backup by asynchronization,and further prevented data tampering and falsification through the certificate of all blocks.Performance comparison and analysis with Bitcoin and Hyperledger show that this model have both high throughput and security,enterprise nodes can move on chain quickly with only a small amount of storage and bandwidth resources.In best case,the minimum local resolution delay of new identity system can be 6ms.
