## On-Chain Finality

On-Chain Finality is the point at which a transaction is considered permanently settled and cannot be reversed or altered by the network. Different blockchain architectures have varying levels of finality, with some providing probabilistic finality and others offering deterministic finality.

In the context of derivatives and high-frequency trading, achieving fast and reliable finality is crucial for risk management and capital efficiency. If a system relies on probabilistic finality, there is a risk that a trade could be reorganized, creating systemic instability.

Ensuring robust on-chain finality is a key challenge for protocol designers building secure financial infrastructure.
