Consensus Finality
Consensus finality is the property of a blockchain that guarantees that once a transaction is confirmed, it is immutable and cannot be reverted. This is essential for derivatives where legal certainty of settlement is required to maintain collateral integrity.
Different networks have different thresholds for what constitutes finality, often involving a specific number of block confirmations. In systems with slow finality, traders face the risk of chain reorganizations, where a competing chain could replace the current one, effectively reversing settled trades.
Ensuring fast and reliable finality is a primary goal for blockchain architects building infrastructure for professional financial derivatives. It bridges the gap between decentralized technology and traditional settlement requirements.
