Checkpoint Finality

Checkpoint finality is a mechanism that provides a guarantee that a specific block and all its predecessors cannot be changed. By periodically committing the state of the blockchain to a fixed point, the protocol achieves a high degree of certainty for financial transactions.

This is essential for derivatives platforms that require fast and reliable settlement without the risk of future chain reorganizations. If a checkpoint is reached, the transaction is considered irreversible, even if an attacker attempts to produce a longer chain later.

This feature significantly enhances the security of the ledger but requires careful coordination among validators. It balances the trade-off between the speed of transaction processing and the absolute security of the final state.
