This Standards Track ZIP specifies a deterministic algorithm for scanning Orchard notes in Zcash wallets. The specification ensures that all wallet implementations produce identical results when scanning the same block range, addressing critical issues with wallet reliability and interoperability. Key features: - Deterministic block, transaction, and action processing order - Comprehensive note deduplication and spent status tracking - Test vectors for verification - Reference implementation from NozyWallet - Backward compatible with existing ZIPs

This is incorrect. The state of the wallet is a function of the contents of the blockchain; the order of scanning is irrelevant (modulo implementation bugs.)

Same issue, this is also flatly incorrect.

Interoperability concerns are the purview of ZIP 315. If there are specific standards required for interoperability (such as standards around key handling), I would recommend that you suggest them there.

Closing with @daira and @arya2; this proposal is based on a misconception about wallet state being dependent on scanning order. While this may be ephemerally true (different scanning algorithms will achieve different intermediate states) when a wallet has fully scanned the chain its value MUST be a deterministic function of chain contents irrespective of scanning order. |
