How Does Collision Resistance Impact the Final Settlement of a Cryptocurrency Trade?

Collision resistance is fundamental to final settlement because it guarantees the uniqueness and integrity of the transaction that executes the trade. If a collision were possible, a fraudulent transaction could masquerade as the legitimate trade, leading to a double-spend or a repudiated settlement.

The inability to forge a hash ensures that once a trade is confirmed in a block, its record is immutable and undeniable, providing the cryptographic assurance required for finality.
