Hard Finality

Finality

The concept of hard finality, particularly within cryptocurrency and derivatives markets, signifies an irreversible state of a transaction or settlement. Unlike probabilistic finality, which relies on statistical confidence, hard finality implies a guaranteed and unchangeable outcome. This is often achieved through mechanisms like Byzantine Fault Tolerance (BFT) consensus or legally binding settlement processes in traditional finance, ensuring that once a transaction is finalized, it cannot be reversed or altered, regardless of subsequent events or malicious attempts. The assurance of hard finality is paramount for trust and stability within these systems.
