NewNullifier

Event emitted when a nullifier is used to spend an input.This event is emitted for each input nullifier used in a privacy-preserving transaction. It ensures that each input can only be spent once, preventing double-spending attacks. # Security Purpose - Prevents double-spending by tracking spent inputs - The nullifier reveals no information about the original input - Provides cryptographic proof of input ownership and spending # Usage - External systems can track spent inputs - Enables efficient double-spending detection - Maintains privacy while ensuring transaction validity
