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.
