  • IIW Discussion
    • 101 sessions already full
    • Maybe we'll just yolo a 101 session
    • Provenant Demo (with credentials)
    • Kent suggested a session describing pulling together the current stack (KERIA/Signifypy/Signify-TS) - perhaps we build off Phils' published "how to do delegated multisig" with the current stack
  • Should we merge PTEL (Public Transaction Event Logs) as Addendum to ACDC Spec because we describe different TEL mechanisms for Privacy Protecting  Disclosure
    • Should we add specific TEL semantics as addendums as opposed to separate specs?
      • Kevin thinks it makes snse to merge the two
      • Phil wants to argue...
        • worried we have two private/public already...
        • Plus we have ipex potentially merged in
        • maybe too much to add?
        • Maybe it makes sense to try the addendums
          • One ref to a EL
            • then two refs one to public
            • one to private
      • Resolution - Draft a ACDC spec with addendums
  • Continue ACDC Disclosure Mechanisms Discussion
    • Bulk Issued Private ACDCs
      • Discussion differentiating between permissioned correlation and un-permissioned correlation.
      • "Selective disclosure can be considered a type of naive de-identification" - Dr Sam Smith
      • Each ACDC has a unique SAID, so it is no longer a point of correlation.
      • Like a HDK we're (pre) generating nonces (that can be anchored) and populating the UUID field.
        • and aggregate of blinded digests
          • becomes the identifier for the revocation
