Network Finality

Definition

Network finality refers to the point at which a transaction on a blockchain is considered irreversible and permanent. This concept describes the assurance that once a transaction has been confirmed on a blockchain, it cannot be altered, reversed, or removed, providing a high degree of certainty for participants. Different consensus mechanisms offer varying levels of finality, from probabilistic (where the likelihood of reversal decreases over time) to deterministic (where reversal is cryptographically impossible after a certain point). Achieving strong finality is paramount for trust and security in digital asset transactions.
