Abstract:

[Objective] This paper mainly introduces problems of current network development and key technologies of the blockchain-based cyberspace identification system. It aims to provide a reference for the subsequent works. [Methods] This paper analyzes the current research status of the blockchain-based network identification system, introduces the architecture designs and technical solutions of the systems such as Namecoin, Blockstack, Handshake, Ethereum Name Service, and compares different projects. [Results] Compared with the existing DNS systems, the blockchain-based cyberspace identification has realized a secure, distributed, decentralized, and censorship-resistant network infrastructure. It is also used in active exploration and cooperation in the field of digital authentication and global unified identification, and has got a certain degree of application. [Conclusions] The blockchain-based network identification service provides a new idea and represents a trend for the development of basic network resources in the future. There are still several problems that need to be solved, such as, how to deal with the relationship with the existing systems and how to extend the application of the system widely.
