论文摘要
HotStuff协议是拜占庭式容错（BFT）共识的突破，既享有响应性和线性视图的变化。它创造性地增加了经典BFT协议（例如PBFT）的额外回合。这使我们提出了一个有趣的问题：在实践中，这一额外的一轮真的需要吗？在本文中，我们通过设计一种名为Fast-HotStuff的新的两轮BFT协议来回答这个问题，该协议享有响应能力和有效的视图变化，与性能方面的线性视图更改相当。与（三轮）热门相比，Fast-HotStuff具有较低的延迟，并且对HotStuff容易受到影响的性能攻击更加强大。
The HotStuff protocol is a breakthrough in Byzantine Fault Tolerant (BFT) consensus that enjoys both responsiveness and linear view change. It creatively adds an additional round to classic BFT protocols (like PBFT) using two rounds. This brings us to an interesting question: Is this additional round really necessary in practice? In this paper, we answer this question by designing a new two-round BFT protocol called Fast-HotStuff, which enjoys responsiveness and efficient view change that is comparable to linear view change in terms of performance. Compared to (three-round) HotStuff, Fast-HotStuff has lower latency and is more robust against performance attacks that HotStuff is susceptible to.
