Define ‘Probabilistic Finality’ as It Applies to PoW.

Probabilistic finality in Proof-of-Work means that a transaction is considered 'final' only after a certain number of blocks have been mined on top of it, making it statistically improbable for the transaction to be reversed. The certainty of finality increases with each subsequent block, but it is never 100% guaranteed, only highly probable.

The industry standard is often 6 confirmations.
