Bitcoin transactions become increasingly costly to reverse as proof-of-work confirmations accumulate, rather than reaching an instant legal-style final state.
Probabilistic settlement finality is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
Probabilistic settlement finality sits between protocol rules, economic incentives and software operated by independent participants. In Bitcoin, no component is authoritative by itself: miners propose history, fully validating nodes enforce validity, and users decide which rules and software they accept.
Understanding Probabilistic settlement finality helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
For the clearest picture, read this entry together with Confirmation, Chain reorganization, Settlement risk, Proof of Work. The reverse links also lead from Nakamoto consensus, Settlement risk, Delivery versus payment.
