## Probabilistic Consensus

Probabilistic consensus is a model where transaction finality is achieved over time rather than being guaranteed at the moment of inclusion. The longer a transaction remains on the chain, the more likely it is to be permanent, as the computational work required to reverse it grows exponentially.

This model is common in Proof of Work networks like Bitcoin. For financial derivatives, this introduces a dependency on time-based risk assessment.

Traders must balance the desire for fast settlement with the statistical risk of a reorg. In contrast to deterministic finality, probabilistic systems require active monitoring of the network's health and confirmation depth.

This adds a layer of complexity to the management of margin and collateral, as the system must account for the non-zero probability of chain reversals. Understanding the mathematical bounds of this probability is a key skill for quantitative analysts working in the cryptocurrency space.
