## Blockchain Consensus Finality

Blockchain consensus finality is the process by which a network reaches an agreement on the state of the ledger, ensuring that once a transaction is included, it cannot be reversed. Different consensus mechanisms offer varying levels of finality; for example, Proof of Work relies on probabilistic finality, where the likelihood of reversal decreases with each additional block.

Proof of Stake protocols often implement deterministic finality, where a transaction is final once a specific set of validators confirms it. For financial derivatives, deterministic finality is preferred as it eliminates the risk of chain reorganization, which could otherwise invalidate margin calls or liquidations.

This technical property is fundamental to the design of secure, high-stakes financial applications on distributed ledgers.
