## Finality in Blockchain Settlement

Finality is the point at which a transaction on a blockchain is considered irreversible and permanent. Once a transaction reaches finality, it cannot be undone or modified by the network.

Different blockchains have different timeframes for achieving finality, ranging from a few seconds to several minutes or even hours. In financial derivatives trading, rapid finality is critical for high-frequency operations and managing margin requirements.

If finality is delayed, there is a risk of temporary inconsistency in the ledger, which can be exploited. Protocols must account for the specific finality characteristics of their underlying blockchain to ensure accurate and safe financial settlement.
