This article examines where Lamport's original oral-messages Byzantine Generals algorithm does and does not apply in practice, contrasting unsuitable cases like distributed databases and rocket launches with a suitable case in redundant flight control systems.

This follow-up factors Lamport’s Byzantine Generals algorithm into a generalized class that's independent of I/O and payloads. Any node can initiate a round (be "king"), values can be arbitrary strings, and multiple rounds can run concurrently.

I discuss Lamport's Byzantine Generals problem and why it requires a total of N≥3M+1 nodes with M malicious nodes, and then implement the solution using Python with HTTP Flask servers.
