Similarly, Max Zorn used to ask people whether they recalled what Zorn's Lemma was introduced as a lemma to. (I haven't a clue, and I doubt most of them did either.)

Wow, that's amazing. On the topic of fault tolerance and consensus, here's a short but well done article on it:

And on the topic of Paxos, some recent HN discussion:

https://news.ycombinator.com/item?id=16003662 - WPaxos: a wide area network Paxos protocol

https://news.ycombinator.com/item?id=13923949 - Paxos in 25 Lines

Are we there yet? Do we need paxos-like consensus protocols? Hardware is becoming cheaper and commoditised and with all the hype around blockchain, it looks like people are ready to pay extra for the redundant hardware needed for 100% fault tolerance. Still, it feels to me to in almost all cases, including financial transactions, it's good enough to be right 99.999% of the time and just amortise the costs of the very rare bit flip...

Page 82 of https://www.sciencedirect.com/science/article/pii/0315086078... has some information.

Zorn introduced a "maximal principle" as an axiom. It appears Tukey called a generalization of it Zorn's Lemma for unknown reasons, though there is some version of the statement that really is proved, but apparently by Chevalley (a fact Zorn knew).
