We introduce new techniques for proving lower bounds on the running time of randomized algorithms for asynchronous agreement against powerful adversaries.

For our third result, we show a lower bound for Byzantine fault tolerant CA without PKI. 418. With a Byzantine adversary and no PKI, the faulty parties are able ...

It is impossible to solve crash fault tolerant BCA in 1 round when 2f + 1 ≤ n ≤ 3f, and the adversary can adaptively choose the inputs of the parties. We next ...
