The Dolev-Reischuk bound says that any deterministic Byzantine consensusprotocol has (at least) quadratic communication complexity in the worst case.While it has been shown that the bound is tight in synchronous environments, itis still unknown whether a consensus protocol with quadratic communicationcomplexity can be obtained in partial synchrony. Until now, the most efficientknown solutions for Byzantine consensus in partially synchronous settings hadcubic communication complexity (e.g., HotStuff, binary DBFT).  This paper closes the existing gap by introducing SQuad, a partiallysynchronous Byzantine consensus protocol with quadratic worst-casecommunication complexity. In addition, SQuad is optimally-resilient andachieves linear worst-case latency complexity. The key technical contributionunderlying SQuad lies in the way we solve view synchronization, the problem ofbringing all correct processes to the same view with a correct leader forsufficiently long. Concretely, we present RareSync, a view synchronizationprotocol with quadratic communication complexity and linear latency complexity,which we utilize in order to obtain SQuad.
