Transaction Finality

Confirmation

Transaction finality refers to the assurance that a transaction, once recorded on the blockchain, cannot be reversed or altered. The level of finality varies across different consensus mechanisms, with some blockchains offering probabilistic finality (e.g., Proof-of-Work) and others offering deterministic finality (e.g., Proof-of-Stake). The time required for confirmation directly impacts the speed of settlement for financial applications.
