  1. Nice to see there's new consensus features!

    1. How's the scalability now? (e.g., in terms of thousands nodes)
    2. Have you evaluated or considered hotstuff (in Libra), which claims novel.
    1. Thanks! Most of the recent consensus work focused on PBFT which is geared towards smaller networks. We have not evaluated hotstuff.
