Synchronous t-resilient Consensus in Arbitrary Graphs ☆, ☆☆ Webany consensus protocol for nprocesses in an asynchronous system uses at least n 1 registers. Our lower bound uses a more re ned notion of valency (introduced in [FLP85]) combined with a covering argument (introduced in [BL93]). As in [FHS98, Gel15, Zhu15], the bound holds even if the registers are of unbounded size.
