Announcing v0.5 of the did:webvh (formerly did:tdw) DID Method Specification

We’re pleased to announce the release of Version 0.5 of the did:webvh specification. The did:webvh DID method builds on the simplicity of did:web while addressing important key management security and integrity challenges, offering verifiable history of DIDs as a foundation for trust. This specification aims to provide a robust, scalable, and interoperable approach to decentralized identifiers (DIDs), leveraging web technologies to simplify adoption while enhancing security.

This update introduces several significant changes, including the new name—did:webvh—which better reflects the DID method’s focus on “did:web + verifiable history”. The previous name, did:tdw, was perhaps too lighthearted and less descriptive of the method's intent.

Alongside the name change, we’re unveiling a fresh logo to symbolize the method’s progress and its goals of clarity, trust, and innovation. The updates in Version 0.5 include:

  *   Tightening Pre-Rotation: Once pre-rotation is activated for a did:webvh the authorization keys must be updated on each new version, and each version must have a proof signed by a key committed to in the previous version.
  *   Enhanced Witness Handling: Witness data proofs have been moved from the DID log file to a separate file (did-witness.json) for easier handling. The witness threshold algorithm has been simplified and we have made it a requirement that all witness DIDs must be did:key DIDs.

This release reflects our commitment to iterative improvement and feedback from the community. In parallel with these specification updates, implementation efforts are already underway in Python, TypeScript, Rust, and Go, ensuring a robust and interoperable foundation for this method.

We invite you to review the updated did:webhv information site and specification at https:didwebvh.info<http://didwebvh.info/> and provide your feedback via issues in the specification repository. Your input is invaluable as we continue to advance the did:webvh DID method and its contributions to the broader decentralized identity ecosystem.

Thank you to all contributors and supporters who have helped bring this vision to life. Together, we’re building a more secure, interoperable, and decentralized future.
