Blockchain-Based DNS Root Zone Management Decentralization for Internet of Things

Domain Name System (DNS) is a widely used infrastructure for remote control and batch management of IoT devices. As critical Internet infrastructure, DNS structured as tree-like hierarchy with single root zone authority at the top, which puts operation risk from point failure. The current lack transparency accountability, since only file published final outcome operations inside authority. Towards distributed in DNS, this paper presents blockchain-based architecture—RootChain, composed multiple servers. On basis maintaining top-level domain (TLD), RootChain decentralizes TLD data publication by empowering delegated authorities to publish authenticated directly. accountability are attained smart-contracting whole life cycle logging all on chain. transparent recursive/stub resolver DNS/DNSSEC-compatible. A proof-of-concept prototype has been implemented Hyperledger Fabric evaluated experiments.
