Byzantine fault-tolerant (BFT) protocols are known to suffer from the scalability issue. Indeed, their performance degrades drastically as the number of replicas $n$ grows. While a long line of work has attempted to achieve the scalability goal, these works can only scale to roughly a hundred replicas.


In this paper, we develop BFT protocols from the so-called committee sampling approach that selects …
