## Protocol Finality

Protocol finality is the point in time when a transaction or a set of transactions is considered permanently committed to the blockchain and cannot be reversed or altered. In the context of financial derivatives, rapid and deterministic finality is critical for high-frequency trading and risk management.

If a protocol has slow or probabilistic finality, traders face the risk of re-orgs, where a previously confirmed trade is wiped out by a longer chain, potentially leading to incorrect margin calculations or unintended liquidations. Different consensus mechanisms offer varying speeds of finality, ranging from immediate deterministic finality in BFT-based systems to probabilistic finality in proof-of-work models.

Understanding the specific finality guarantees of a blockchain is essential for designing derivative platforms that require precise settlement and real-time collateral tracking.
