A look at Byzantine fault tolerance:
PBFT (Practical Byzantine Fault Tolerance), published by Castro and Liskov in 1999, made BFT consensus practical in real-world systems.
BFT-style consensus requires multiple rounds of voting communication between nodes. The more validators there are, the greater the volume of messages, so the number of validators directly participating in consensus is often limited.
