Order Finality

Order finality refers to the point at which a transaction is considered irreversible and cannot be altered or removed from the blockchain ledger. In financial derivatives, finality is crucial because it defines when a position is legally opened or closed.

Different consensus mechanisms offer varying speeds and guarantees of finality, which directly impacts trading strategy. Fast finality allows for quicker feedback loops and reduced risk, whereas probabilistic finality requires waiting for multiple block confirmations.

Understanding the finality characteristics of a specific chain is essential for risk assessment in high-frequency trading.
