URLile

URLile is a proposed web infrastructure concept designed to enhance privacy and durability of URLs by decoupling identity from destination and adding a verifiable mapping layer. It envisions a decentralized registry of URL mappings that can be queried over privacy-preserving networks, with cryptographic proofs that mappings are authentic and up to date. The system aims to coexist with existing DNS and HTTP(S) but offers an alternative path for sensitive URL lookups.

Origin and development: First described in technical white papers in the early 2020s by researchers affiliated with the Open Web Foundation; subsequent proposals explored integration with DoH/DoT and content-addressable storage. Scope includes both consumer browsing and enterprise URL governance.

Technology overview: URLile uses a distributed registry, where each URL name resolves to a pointer that is cryptographically signed by the mapping authority. Lookups are performed through a privacy-preserving network that hides query content and origin. Mappings may be versioned, enabling historical audits and rollback. The system emphasizes opt-in privacy and compatibility adapters for existing browsers.

Criticism and limitations: Critics note potential performance overhead, risk of fragmentation if adopted unevenly, and governance concerns about who issues mapping attestations. Interoperability with traditional DNS and with HTTPS security remains a key integration challenge.

Adoption status: As of now, URLile remains experimental and not widely deployed; interest centers on privacy advocates and certain enterprise networks.
