Finality Speed

Definition ∞ Finality Speed quantifies the duration required for a transaction on a blockchain to achieve irreversible status and be permanently recorded on the ledger. A higher finality speed indicates that transactions are confirmed and settled more rapidly, effectively reducing the potential for double-spending or chain reorganizations. This metric is a key indicator of network efficiency.
Context ∞ The Finality Speed of various blockchain protocols is a crucial performance metric frequently discussed in crypto news, particularly when evaluating different layer-1 solutions or layer-2 scaling technologies. Enhancements in finality speed are sought to enable high-throughput applications and facilitate quicker settlement in decentralized finance, significantly improving user experience.
