  Next Week

  ...

  • Proposals for an Aries SDK
    • Key questions:
      • Should there be an Aries SDK, used by most language frameworks?
      • Should it be in Rust?
      • What parts of Indy should we take?
      • How should it change over time?
    • Discussion summary:
      • A Rust C-callable API is very useful for functions that are common across the various Agents.
      • A ledger resolver API below the C-callable API is really useful, but higher level functions for writing schema defs and cred defs should be implemented on top of those primitives by the language libraries
        • Need to recruit a second ledger implementation besides Indy to ensure that the resolver API is sufficiently generic.
