Decentralized Domain Name System (DDNS)

The modern internet's Domain Name System (DNS) represents a critical infrastructure vulnerability that undermines both security and freedom of information. Two primary categories of threats have emerged as systemic challenges: **DNS Security Vulnerabilities:** The centralized architecture of traditional DNS systems creates attractive targets for sophisticated attacks. Recent evidence includes the APT Group StormBamboo attacks, which compromised ISP-level DNS infrastructure to redirect legitimate traffic to malicious endpoints [1]. These poisoning attacks exploit the inherent trust relationships in hierarchical DNS resolution, demonstrating how centralized control points become systemic weaknesses [33,34]. … **Ethereum Name Service (ENS):** Utilizes Ethereum's smart contract infrastructure for .eth domain management [3]. While innovative, ENS faces scalability constraints due to Ethereum's throughput limitations (Max Theor. TPS 119.1 tx/s) and high transaction costs (gas fees often exceeding $50 per operation). Additionally, ENS domains are not compatible with traditional DNS infrastructure, limiting their utility [47].
