## Message Hash Verification

Message hash verification is the process of confirming that a digital signature corresponds to the exact message or transaction data that was intended. Before a signature is generated, the transaction data is typically hashed to create a fixed-length representation.

The signature is then applied to this hash rather than the raw data, which is more efficient and secure. During verification, the receiver hashes the received transaction data and compares it to the hash associated with the signature.

If they match, the transaction is verified as authentic and unaltered. This process is the core of how nodes ensure that transactions remain intact as they propagate across the network.

It prevents man-in-the-middle attacks where data might be modified in transit.
