Finality Gadget
A finality gadget is a secondary mechanism layered over a consensus protocol to provide deterministic confirmation of transactions. In the context of protocol physics, it transitions a block from a probabilistic state to an immutable state.
Once a block is finalized by the gadget, it cannot be reverted or altered without a massive, verifiable violation of the protocol rules. This is critical for financial derivatives, as traders need certainty that their positions and settlements are irreversible.
By decoupling block production from finality, protocols can achieve faster transaction processing while maintaining a high standard of security. It prevents common risks associated with chain reorganizations and ensures reliable price discovery.
