SDK 2.0 architecture / Indy-Aries split (Sergey)
- http://jira.hyperledger.org/browse/IS-1285

RFC Progress

Other Business

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.

    - Should payments belong in Aries (libnullpay?)
  - https://docs.google.com/drawings/d/1sUffkRPlufingeeRjjBniVt9Ek3CNih9lUqym8mUl4M/edit?usp=sharing Aries Architecture
