基于DID的跨链身份认证研究综述
Overview of Cross-Chain Identity Authentication Based on DID
摘要
Abstract
With the emergence of concepts such as metaverse and Web3.0,blockchain plays a very important role in many fields.Cross-chain technology is an important technical means to achieve inter-chain interconnection and value transfer.At this stage,traditional cross-chain technologies such as notary and sidechain have trust issues.At the same time,in the field of cross-chain identity authentication,there are problems that the identities of each chain are not unified and users do not have control over their own identities.Firstly,it systematically summarizes the develop-ment process and technical solutions of digital identity and cross-chain technology,and analyzes and compares four digital identity models and nine mainstream cross-chain projects.Secondly,by analyzing the main research results of cross-chain identity authentication in recent years,a general model of cross-chain identity authentication is de-signed,and the shortcomings of existing solutions are summarized.Then,it focuses on the cross-chain identity au-thentication implementation scheme based on DID,and analyzes the technical characteristics,advantages and disad-vantages of different solutions.On this basis,three DID-based cross-chain identity authentication models are sum-marized,the main implementation steps are functionally described,and their advantages,limitations and efficiency are analyzed.Finally,in view of the shortcomings of the current DID-based cross-chain identity authentication model,its development difficulties are discussed and five possible future research directions are given.关键词
