Licensing

AGTS-conforming implementations

AGTS is a proposed open standard. Implementations that conform to the AGTS specification suite for the purpose of interoperating with an ObligationSign clearinghouse or transparency log are permitted under a royalty-free license to the claims of EP 25 000 039.5 and EP25209644, subject to the following conditions:

  • The implementation declares conformance to the AGTS specification (version number referenced)
  • The implementation does not assert IP claims against other AGTS-conforming implementations
  • The implementation does not use AGTS terminology to describe a non-conforming product

For commercial deployments not covered by the above, or for questions about the scope of the royalty-free license: legal@obligationsign.com

Sovereign Authority — published public key

The Sovereign Authority ECDSA P-256 public key (SPKI, base64) is published here and in the GitHub repository at /public-keys/sovereign-authority.spki.b64. The node_id is the SHA-256 of the DER bytes of this SPKI.

[Key ceremony not yet performed — key will be published after the Pixel Titan M2 Sovereign Authority key generation ceremony. See deployment roadmap.]

The key ceremony must be performed on a GrapheneOS Pixel device with StrongBox-backed key generation (setIsStrongBoxBacked(true)) before any production Governance Envelopes are signed. The key generation date will be noted here. The key cannot be exported.
