Query and Create Exercise as multiple parties

Ledger API supports multi-party reads, JSON API does not.

JSON API authentication/authorization was designed a bit a head of Ledger API and we did not have a use case for multi-party reads in JSON API.

Our take on multi-party authentication in JSON API:

  • 1 party - 1 authentication token (JWT), no super users
  • if participant needs to act as multi-party, this participant needs multiple authentication tokens (one per party)
