The IC consensus protocol provides _cryptographically guaranteed finality_. The option of choosing _probabilistic finality_ – similar to what is done in Bitcoin-like protocols, by considering a block final once a sufficient number of blocks have built on top of it in the blockchain – is not acceptable for the IC for two reasons: (1) probabilistic finality is a very weak notion of finality and (2) probabilistic finality would increase the time to finality drastically.
