DNSrl

DNSrl is a proposed decentralized domain name resolution system intended to augment the traditional Domain Name System (DNS) by enabling verifiable, censorship-resistant mapping from domain names to network addresses through a distributed network of resolvers. The project envisions an optional layer that can operate alongside DNS, allowing users to query either standard DNS or DNSrl resolvers and to bridge between the two when needed.

Technically, DNSrl relies on a community of validators and resolvers that maintain signed zone data in a distributed ledger or similar data store. Domain records are published with cryptographic proofs, enabling clients to verify the authenticity of answers without relying on a single authority. Queries are validated against public keys or commitments, and results are delivered with proofs that demonstrate their integrity.

DNSrl emphasizes decentralization, data integrity, and resilience to censorship, while aiming for interoperability with existing DNS semantics. The ecosystem is described as open-source and governance-driven, with proposals, community input, and transparent roadmaps guiding development. Adoption is incremental and voluntary, focusing on use cases where verifiability and resistance to interference are valued, such as critical services or privacy-conscious users.

Critics note potential drawbacks, including added complexity, performance overhead, and the need for broad operator participation to achieve scale. Compatibility challenges with legacy infrastructure and the economics of maintaining incentives for validators are discussed in ongoing debates. Proponents argue that DNSrl can complement rather than replace DNS, providing an extra layer of trust for those who require it.
