First, let's think about a question first, why is the maximum number of fault-tolerant nodes of the pbft algorithm (n-1)/3, and the maximum number of fault-tolerant nodes of the raft algorithm is (n-1)/2?
For the raft algorithm, the fault tolerance of the raft algorithm only supports fault-tolerant fault nodes, not fault-tolerant nodes. What is a faulty node? It is a node that does not respond due to other abnormal conditions such as system busy, downtime,…
