Preimage Revelation Protocol

The preimage revelation protocol is the technical process by which a user proves they possess the secret value required to unlock funds held in a hash time locked contract. By revealing the preimage, the user fulfills the cryptographic condition of the contract, allowing the settlement to proceed on the blockchain.

This action is the decisive moment in an atomic swap or a secure payment channel, confirming the transaction's validity. If the preimage is not revealed before the time-lock expires, the contract defaults, protecting the sender.

It is a fundamental mechanism for ensuring secure and verifiable state transitions in distributed ledger technology.
