Abstract
With the continuous development of the Internet, the domain name system (DNS) as infrastructure is playing an increasingly important role. However, traditional DNS architecture is centralized, and there are some security problems such as the right concentration and power abuse. This paper combines blockchain technology with DNS technology and proposes a domain name service model based on the permissioned blockchain. At first, this paper designs a top-level domain chain (TLDChain) model to conduct consensus on block transactions and achieve decentralization of domain name service. Then, this paper introduces a data model to upload data. At the same time, to improve the efficiency of the blockchain data query, this paper proposes a data warehouse to speed up the query. Also, it designs the domain name data synchronization algorithm and consistency checking algorithm to achieve synchronization and quick consistency checking of domain name data. At last, this paper introduces the domain name resolution process of this model. Experimental results show that the proposed DNS service model not only realizes the decentralization of domain name resolution but also improves query efficiency.
