Opening Phase

The opening phase is the final step in a commitment scheme where the sender reveals the original value that was previously committed to. This reveals the hidden information to the receiver, who then checks the revealed value against the initial commitment to ensure it matches.

This process confirms that the commitment was indeed what the sender claimed it to be, without the sender having been able to alter the value in the meantime. In financial applications, this phase is critical for executing trades, settling derivatives, or finalizing governance votes.

It is the moment of truth where privacy is exchanged for public proof.
