## Consensus Finality Risk

Consensus finality risk refers to the possibility that a transaction, once included in a block, could be reverted or reorganized due to network instability or an attack. Finality is the state where a transaction is considered irreversible, meaning it cannot be altered or removed from the blockchain.

Different consensus mechanisms offer varying degrees of finality, with some providing probabilistic finality and others providing deterministic finality. In systems with low finality guarantees, users and protocols face risks related to chain reorganizations, where a competing chain with more work replaces the current one.

This risk is particularly high in derivatives trading, where fast settlement is required to prevent arbitrage and ensure accurate margin calculations. Managing finality risk involves understanding the time required for a block to become immutable and the economic cost required to reorganize the chain.

It is a fundamental concept in protocol physics that dictates how financial applications are built on top of a blockchain. High finality risk can lead to contagion if collateralized positions are liquidated based on data that is subsequently reverted.
