Webvariant of consensus known as ledger consensus plays a crucial role, cf. [4]. A hallmark feature of such protocols is their Byzantine fault tolerance (BFT), i.e., their ability to tolerate participants that arbitrarily deviate from the specification of the protocol, even when these deviations may be orchestrated by an adversarial entity.
