Discussion Topics

• OCA for Aries RFC update -- a summary of the recent changes
  • PR: https://github.com/hyperledger/aries-rfcs/pull/755
  • RFC 0755 OCA for Aries: https://github.com/swcurran/aries-rfcs/blob/oca4aries/features/0755-oca-for-aries/README.md
  • RFC 0756 OCA for Aries Style Guide: https://github.com/swcurran/aries-rfcs/blob/oca4aries/features/0756-oca-for-aries-style-guide/README.md
• Race conditions in establishing mediated connections
  • When the client of a mediator is establishing a connection to another agent, they must:
    • Send a message to the mediator to add the new DID/Key for the connection (RFC 0211 keylist-update message)
    • Send a message to the other agent – RFC 0160 Connections or RFC 0023 DID Exchange "request" message.
    • Load testing shows that this is problematic – sometimes the response from the other agent comes to the mediator before the keylist-update is complete.
  • Found to be the case in ACA-Py – being serialized.  Issue #2073.
  • Suggest checking Aries Framework JavaScript / Aries Bifold to see if it is an issue there.
  • If performance is affected – could "pre-allocate" some number (even 1) Key and do the keylist-update as a background task, similar to the way revocation registries are handled in ACA-Py.
