WebIn an open, trustless and distributed setting adversaries can act maliciously in many ways. For example, an attacker can make multiple pseudonyms and do a sybil attack1, and … WebIn a recent distributed algorithm for this purpose, each processor maintains a delayed view of the pending work, which is represented in terms of points in virtual time. This paper presents a formal specification of that algorithm in the temporal logic TLA, and describes a mechanically verified correctness proof of its main properties.
