Authorization deserialization fix #2478

Closed lukenewman closed 5 months ago

lukenewman commented 5 months ago

Motivation

When deserializing an Authorization from string a call stack that included multiple transitions, the structural assertion logic would erroneously fail. This PR fixes the assertion logic but does not change the underlying structure/order of the Authorization fields.

Test Plan

Our (Puzzle) delegated proving stack takes in user-generated Authorizations in string form. We then parse these and execute the proof request using snarkVM crates. I've tested that these Authorization deserializations and subsequent proofs do indeed land onchain properly.

I can provide screenshots/videos on request. For now, you can see the following transaction that was generated through our stack and has landed onchain: https://testnet.aleoscan.io/transaction?id=at14d4edujs6ztghev2zppp55v4xlffu7q3p379dlvdsu3yuu2cluysd84ktk

I am also willing to create a sample project showing this fix in action.

A more formal test plan would involve embedding a multi-transition Authorization unit test into snarkVM itself and not just relying on a fee_public test case.
