How to study this repo

  1. 1
    Follow request identity

    Track client and request numbers through retries and replica deduplication.

  2. 2
    Check an invariant

    Find where transfer flags and account balances are validated.

  3. 3
    Reach durable state

    Trace a committed operation from the state machine into grid blocks.
