A Study Of Key Techniques In Blockchain-based Identity Parsing

The World Wide Web is an important system of the current Internet,which allows people to exchange information on the Internet.The current process of exchanging information relies on two centralized systems of the World Wide Web: the centralization of the domain name system and the centralization of web servers.However,these two centralizations pose a lot of problems.For the centralization of the domain name system,the current domain name resolution is hierarchical,and all top-level domain name data needs to be resolved by one of the 13 root servers.For the centralization of website servers,most of the current website servers are C/S structures,which leads to the fact that user data is controlled by the company,and the management of data in the company is not transparent.And these two centralized systems are prone to single-point failure problems.Blockchain is a distributed ledger technology that can run in a weak trust environment.It has the characteristics of decentralization,tamper-proof,and high reliability.Therefore,the blockchain is very suitable for tamper-proof and highly reliable identification in a weak trust environment.Parse the scene.Aiming at the centralization of domain name resolution and the centralization of content acquisition,this paper proposes a key technology for identity resolution based on blockchain.The method combines the identification analysis with the blockchain,decentralizes the analysis service,and at the same time integrates the identification analysis of the blockchain and the distributed content analysis into the existing Internet analysis system.Aiming at the centralization problem in the DNS resolution process and the low resolution efficiency caused by multi-level resolution,this paper proposes a domain name resolution technology based on ENS.This technology reduces the number of queries for domain name resolution to one,and at the same time decentralizes the resolution service.On this basis,it increases the resolution of the common blockchain address records and content hash records in WEB3.0.In view of the centralization problems that may be caused by the current C/S structure of the Web system,address changes and unreadable addresses caused by content addressing.This paper proposes an IPFS content analysis and acquisition technology,which resolves domain names into IPFS content.According to this technology,an IPFS content acquisition server is designed,which parses domain names into content hashes,and obtains content through content hashes,thereby supporting the acquisition of distributed content through domain names.Based on the above technologies,a distributed content analysis and acquisition system is implemented,including a content analysis subsystem and an ENS-based domain name resolution subsystem.Experiments show that the content parsing subsystem realizes the parsing of dis tributed content,the system performance reaches 1w QPS,and the parsing time is still less than 3s when the maximum stable throughput rate is reached.The ENS-based domain name resolution subsystem realizes the resolution of common DNS records,as well as the resolution of blockchain addresses and content hash records.Tests show that the average delay in resolving records of the domain name resolution subsystem is within 500 ms.The test results show that the system can meet the needs of most users.
