    • Endorser updates
    • Problem Report handling in Credential Exchange protocols

    • Ideally, incorporated into the above, but if not, a third design doc, covering the use of the event bus with the outbound queuing
• Questions – AMA:
  • Issuer backend – 100/second issuances – EU Vaccination Credentials into SSI Credentials.
    • Limit – seem to have 2 issues/second/ACA-Py instance.  BC has scaled to 21 ACA-Py instances and beyond that the returns are limited.
