## Probabilistic Vs Deterministic Finality

Probabilistic vs Deterministic Finality distinguishes between two fundamental ways blockchain networks reach agreement on transaction status. Probabilistic finality, common in proof-of-work systems, means a transaction is never 100% final but becomes increasingly secure as more blocks are added.

Deterministic finality, found in many proof-of-stake protocols, means a transaction is considered final once it has been included in a block that is voted on by a supermajority of validators. For financial derivatives, deterministic finality is often preferred because it removes the risk of chain reorganizations that could invalidate a trade.

However, probabilistic systems are often more resistant to censorship and centralization. Understanding this difference is vital for designing protocols that rely on consistent data for margin calls and liquidation triggers.

It dictates how long a system must wait before considering an action complete.
