Abstract
Although the current Domain Name System (DNS) has been able to satisfy the use of network services, there are still many challenges in the future development of the Internet. The centralized management of traditional domain name management systems has many risks, and cannot defend against Distributed Denial of Service (DDoS) attacks and single points of failure. As a decentralized tool, blockchain provides innovative ideas for the improvement of domain name management systems. Starting from the existing network resolution system and combining the application of cross-chain communication in DNS, this paper proposes a domain name resolution service architecture model based on the master-slave chain, adopts a Multi-Sig Notary Schemes to achieve cross-chain communication, and proposes based on the master-slave chain consensus algorithm (MSBFT) of the PBFT algorithm. In a single blockchain, this paper uses the VRF algorithm to select the master node. Finally, the simulation experiment designed in this paper tests the throughput and analysis delay of the analytical model, compares the analytical delay of the main chain and slave chain, and analyzes the advantages of the model.

Blockchain technology can solve the problem of the high degree of centralization of DNS, and the consortium chain architecture based on the master-slave chain can solve the limitation and efficiency of the single chain operation in the consortium chain [8]
Summary
The Domain Name System (DNS) is the most core part of the Internet. Its main function is to complete the conversion service of domain names to IP addresses for network users all over the world. The structure and service of DNS still have a high degree of centralization. Blockchain has the characteristics of decentralization, transparency, immutability and traceability It can solve the problem of insecurity of data stored on a single node in a centralized system and the high cost of single node performance maintenance. The cross-chain technology of the blockchain makes the blockchain expandable and realizes data communication and asset transfer between different blockchains. The current mainstream cross-chain technologies mainly include: Sidechains/Relays, Hash-locking, Distributed Private Key Control, and Notary Schemes [5]. Blockchain technology can solve the problem of the high degree of centralization of DNS, and the consortium chain architecture based on the master-slave chain can solve the limitation and efficiency of the single chain operation in the consortium chain [8]. This article proposes a new DNS model based on the master-slave chain
