一种基于区块链的域名管理架构模型

A Domain Name Management Architecture Model Based on Blockchain

当前互联网治理模式正朝着平等开放的方向发展,而作为互联网关键基础设施的域名系统(Domain Name System,DNS),其传统管理模式是一种中心化的层级架构,权力滥用、单点信任等安全风险始终存在。区块链技术作为一种新型的去中心化工具,能够给域名系统架构的扁平化改造提供创新性思路,实现全球域名服务提供商之间的共管共治模式。本文从当前域名系统中心化结构的痛点出发,归纳总结域名系统去中心化的解决方案,并在不改变现有业务逻辑的前提下,提出一种基于区块链的域名管理架构模型,通过三层结构的联盟区块链以及“DPoS+BFT”共识机制,实现各顶级域注册局共同参与根区数据管理的新方式。

The current Internet management architecture is developing in the direction of equality and openness.As the key infrastructure of the Internet,the Domain Name System(DNS)whose traditional management model is a hierarchically centralized structure,in results of security risks such as power abuse and single point of trust.As a novel solution of decentralization,blockchain can provide innovative ideas for the flat transformation of DNS architecture and realize a co-management model between global domain name service providers.This paper analyzes and compares the existing decentralization solutions of DNS architecture,then based on the existing DNS business logic,proposes a domain name management architecture model with the three-layer structure of consortium blockchain and“DPoS+BFT”mechanism,in order to realize the participation of the top-level domain registries in root zone data management.
