Equivocation and Omission remain as the only optionsfor an attack on CRDT layer

This implies that any correct run of the imple-mentation that stutters indefinitely has infinitely many opportunities to activatethe specification. Under the standard assumption that an opportunity that ispresented infinitely often is eventually seized, a live implementation does notdeadlock as it eventually activates the specification.

Eine beliebte Klassifizierung dynamischer Eigenschaften liefert die Unterscheidung inSicherheitsbedin-gungen(safety conditions) auf der eine Seite undLebendigkeitsbedingungen(liveness conditions) auf deranderen Seite. Nach [14], S. 94, schließt eine Sicherheitsbedingung das Auftreten von etwas Schlechtem aus, wäh-rend eine Lebendigkeitsbedingung das Auftreten von etwas Gutem garantiert. E
