Besides Pre-Image Resistance, What Is Another Crucial Security Property of a Cryptographic Hash Function?

Collision resistance is another crucial property. This means it is computationally infeasible to find two different inputs that produce the exact same hash output.

If a collision were found in Bitcoin's SHA-256, an attacker could replace a valid transaction with a fraudulent one that generates the same block hash, undermining the security of the entire blockchain.
