# Function notify_nullified_note

Module: `noir_aztec::oracle::notes`

```rust
pub fn notify_nullified_note(nullifier: Field, note_hash: Field, counter: u32)
```

Notifies the simulator that a note has been nullified, so that it is no longer returned in future read requests in the same transaction. This note should only be removed to the non-volatile database if its nullifier is found in an actual block.
