# Prove Operation

### Description

The operation is to prove the ownership previously committed on mint.

The provided proof is zero-knowledge proof which means the underlying owner will not be   exposed though the corresponding shadow address published as the symbolic owner for holding benefits or rights.

The outputs are not interpreted by the protocol.
