## Finality of Transactions

Finality of transactions refers to the point at which a financial transaction is considered irreversible and binding. In traditional banking, this can take days as transactions pass through various clearing and settlement stages.

On a blockchain, finality depends on the consensus mechanism and the probability of a chain reorganization. Once a transaction reaches finality, the assets are effectively transferred and the record cannot be changed.

This is a critical concept for businesses and traders who need to know exactly when their funds are available. Understanding the time to finality is essential for managing operational risk and providing services like instant payments.

Different blockchain protocols have different approaches to finality, ranging from probabilistic to deterministic models. This concept is a core element of protocol physics and the study of how decentralized systems handle value transfer.
