  - "Advances in blockchains have influenced the State-Machine-Replication (SMR) world
    and many state-of-the-art blockchain-SMR solutions are based on two pillars: Chaining
    and Leader-rotation. A predetermined round-robin mechanism used for Leader-rotation,
    however, has an undesirable behavior: crashed parties become designated leaders
    infinitely often, slowing down overall system performance. In this paper, we provide
    a new Leader-Aware SMR framework that, among other desirable properties, formalizes
    a Leader-utilization requirement that bounds the number of rounds whose leaders
    are faulty in crash-only executions.\r\nWe introduce Carousel, a novel, reputation-based
    Leader-rotation solution to achieve Leader-Aware SMR. The challenge in adaptive
    Leader-rotation is that it cannot rely on consensus to determine a leader, since
    consensus itself needs a leader. Carousel uses the available on-chain information
    to determine a leader locally and achieves Liveness despite this difficulty. A
    HotStuff implementation fitted with Carousel demonstrates drastic performance
    improvements: it increases throughput over 2x in faultless settings and provided
    a 20x throughput increase and 5x latency reduction in the presence of faults.@eng"
