feat(logging): add account, note, storage, and mempool lifecycle events by kkovaacs · Pull Request #2358 · 0xMiden/node

kkovaacs · 2026-07-20T13:01:50Z

Summary

Emit lifecycle events after successful block commits for account registration, note creation and consumption, and public account storage changes.
Resolve consumed note IDs from nullifiers on a best-effort basis and identify output notes erased within the same block.
Log mempool transaction additions, expirations, and evictions, distinguishing direct removals from dependent transaction removals.
Improve input-note formatting with explicit nullifier and note_id labels.

Resolves part 2 of issue #2330

When would this happen?

This is specifically for unauthenticated notes that don't have their nullifier in our DB. Maybe this should not even be a warning, because unauthenticated notes created and consumed in the same block would trigger this?

I'm a bit concerned about how this will scale when we want to change how things work in the mempool.

But I guess we'll have to cross that bridge when we get there.

Otherwise the prover crate litters the logs with INFO level events.
