Consensus Finality Guarantees

Finality

⎊ Consensus finality guarantees represent the probabilistic assurance that a transaction, once included in a blockchain, cannot be altered or reversed, a critical element for derivative contract settlement. This assurance stems from the underlying consensus mechanism, influencing the reliability of on-chain financial instruments and reducing counterparty risk. The degree of finality directly impacts the viability of complex financial products built upon blockchain infrastructure, particularly those requiring immutable records. Quantitatively, finality is often assessed through metrics like the cost to attack the network and the time required to achieve a sufficient number of confirmations.
