Specs & Projects

The active work items that are underway

Universal Resolver

Specification and implementation of a driver-based framework that enables resolution of DIDs.

Universal Registrar

Specification and implementation of a driver-based framework that enables creation/updates/deactivation of DIDs.

.well-known DID configuration

Specification, docs, and implementations for discovering DIDs from .well-known HTTP(S) URIs.

Peer DID Method Specification

A rich DID method that has no blockchain dependencies. The verifiable data registry is a synchronization protocol between peers.

DID Specification Extensions

Extension parameters, properties, and values for the DID spec registries.

did:webvh

did:webvh DID Method.

Linked Verifiable Presentation

Specification for linking Verifiable Presentations in DID documents.

DID Traits

Specification for representing DID method traits in a structured, machine-readable format.
