Decentralized DNS
Decentralized DNS (dDNS) refers to naming systems that distribute the authority and storage of DNS records across a peer-to-peer network or blockchain, eliminating single points of failure and central control. Unlike the conventional hierarchical [[dns|DNS]] governed by [[icann|ICANN]], decentralized DNS systems achieve censorship resistance by storing zone data in distributed ledgers or peer-to-peer databases where no single party can unilaterally alter or remove records. Implementations range from fully blockchain-based name registries like [[handshake-protocol|Handshake]] and [[ens|ENS]] to hybrid overlay networks that augment the existing DNS infrastructure with decentralized layers for selected namespaces.
Example
A journalist in a censored region registers their site on a decentralized DNS network, ensuring their domain cannot be seized by a national registry authority.
