Antti Kettunen - generic composable patterns/models; Candidate for future Task Forces

Trust Registry TF — Darrell O'Donnell

• Darrell O'Donnell to get docs into github and share out.
• TR v1.0 to focus on the very limited
• <<DARRELL - add v1.1/v2.0 discussion >>

ACDC TF — Samuel Smith Phil Feairheller 

• First 3 - SAID; CESR; CESR Proof Sigs - out as Draft IETF RFCs.
• Next 2 - re-creation of top-level ACDC specification (template was from TIPs era). Now re-casting in IETF RFC-esque format. 
• Combining Cred Issuance and Presentation Exchange as a first pass. Request A Credential is VERY similar to Request a Proof/Presentation Request
  • Darrell added others are keeping those separate but there is a third (basic comms - Request a Thing where Thing is (Credential | Proof Request / Presentation Request ). This is composability in action.
• casual note that KERI exchange was based on an older (2 IIWs ago) version of WACI PEX (aka Killer Whale Jello Salad)

Technology Architecture TF (TATF) — Drummond Reed

• Very active discussions underway in the Thursday meetings. See the special topic below.

Darrell O'Donnell
and TATF members

See the notes from recent meetings (see diagram #1 below):

• 2022-01-20 TATF Meeting Notes
• KEY to view recording (bullet above)
• DIDComm and KERI are aligning so delineating things is helpful. e.g. Authenticity first and non-Repudiation at the identifier vs. message level were key takeaways. 
• Delayed non-repudiation - e.g. an anonymous and unlinked (zero reputation) identifier can LATER be tied to other identifiers.
• Wenjing - added that DIDComm may need de-/re-composition similar to what's happening at KERI. 
• Privacy & Confidentiality - are these Layer 3 (or boundary 2/3) constructs? Bart Suichies
  • Portability of DIDComm is about abstracting transport and enabling communication of "secure" information.
• DIDComm team - TATF needs input from leaders in DIDComm, particularly in relation to decomposition and KERI learnings.
• +1 on DIDComm references to self-sovereign interactions
