What Is the Byzantine Generals Problem in Distributed Systems?

This is a terrible overview of the problem. If general 3 knows it is general 2 saying that general 1 wants to retreat, they can just ignore it. There is no problem.

(or general c, b, a respectively, since TFA can't keep their numbering straight)

The wikipedia page has a much better overview: https://en.wikipedia.org/wiki/Byzantine_fault#Definition

Posted 4 hours ago, which would have been about 1530 Brussels time... OP at FOSDEM? :-) https://fosdem.org/2025/schedule/event/fosdem-2025-4941-was-...

(Not TFA, which was published Jan 31 - OP, who posted it this afternoon shortly after a talk which included the Byzantine Generals problem)
