Blockchain Finality

Consensus

Blockchain finality is fundamentally achieved through the network’s consensus mechanism, which dictates the probabilistic or absolute certainty of a transaction record being immutable. Proof-of-Work systems offer probabilistic finality based on chain length, contrasting with Proof-of-Stake finality derived from validator attestations and slashing conditions. Traders must quantify the time-to-finality for their chosen chain, as this duration directly impacts settlement risk for derivatives.
