Hi all,

Sorry to be late to the party, for what it's worth - I also support adoption for the same reasons as Walter. I am willing to help out as we go forward and plan to implement the specification.

Thanks,

David.

Subject: [SCITT] SCITT Working Group adoption call for MMR Receipt Profile

SCITT Working Group,

The chairs are issuing a formal Working Group adoption call for  COSE Receipts for MMRs<https://www.ietf.org/archive/id/draft-bryce-cose-receipts-mmr-profile-03.html>. The draft defines a COSE Receipt profile for ledgers based on post order traversal binary Merkle trees, commonly known as Merkle Mountain Ranges. (datatracker.ietf.org)

The profile has been presented to the Working Group, received comments and review, and was updated in response to that feedback. The Working Group also discussed bringing the profile into SCITT during the IETF 126 session. (datatracker.ietf.org)

This call is to determine whether the Working Group agrees that the document is in scope and should be adopted as the basis for continued SCITT work. Adoption does not indicate that the document is complete or ready for publication. Technical issues and design questions may continue to be addressed after adoption.

Please respond to the mailing list by Friday, October 9, 2026, indicating:

* Whether you support or oppose adoption
* The reasoning for your position
* Whether you are willing to review, contribute to, or implement the specification

Technical comments are also welcome, but do not need to be resolved before expressing support for adoption.

Thank you,

Nicole Bates
