Call for Participation in Agent Trust Protocol (ATP) Community Group

The Agent Trust Protocol (ATP) Community Group has been launched:

Autonomous AI agents are being deployed at scale with no open standard governing how they prove identity, establish trust, or protect the privacy of the humans they represent. The mission of the Agent Trust Protocol (ATP) Community Group is to address this gap by producing open specifications that fill the Security and Privacy modules described by the AI Agent Protocol Community Group, modules currently marked as pending community contribution.

This group will create Specifications for:

• the  did:atp  quantum-safe DID method (hybrid Ed25519 + ML-DSA-65 post-quantum signatures)
• an agent trust scoring model backed by W3C Verifiable Credentials
• privacy-first interaction mechanisms including pairwise DIDs, selective disclosure, and zero-knowledge proofs
• a conformance test suite to drive interoperability

This Community Group was formed at the invitation of the AI Agent Protocol CG Chairs and intends to collaborate with that group.

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2026-06-04 by Larry Lewis. The following people supported its creation: Larry Lewis, Venkata Vemuri, MT Monique LaCour, Samuel Denard and Robb Teneo. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group on social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at site-comments@w3.org

Thank you,
W3C Community Development Team
