## Network Finality Guarantees

Network finality guarantees refer to the certainty that a transaction, once included in a block, cannot be reverted or altered. In traditional finance, finality is a legal process, but in blockchain, it is a technical property enforced by the consensus mechanism.

For derivative contracts, which depend on precise execution at specific times, absolute finality is crucial. Probabilistic finality, where a transaction becomes more secure as more blocks are added, may be insufficient for high-stakes financial instruments.

Protocols strive for deterministic finality, where once a block is committed, it is final and immutable. This is achieved through complex consensus rules that require a supermajority of validators to agree before a block is considered finalized.

Understanding these guarantees is essential for assessing the risk of a protocol. If a system relies on weak finality, it may be susceptible to reorg attacks that could invalidate trades and lead to financial loss.

Ensuring strong finality is a prerequisite for institutional-grade decentralized finance.
