Blockchain Finality Latency

Definition

Blockchain finality latency refers to the temporal interval between a transaction’s submission and its irreversible inclusion within a distributed ledger. This period ensures cryptographic proof of validity and resistance to reordering or reversal. Different consensus mechanisms exhibit varying degrees of finality, influencing the time required for a transaction to be considered immutable. The latency is a critical metric for assessing network transaction reliability. It quantifies the time until a block is cryptographically secure.
