I think the article is wrong. Radiation/Cosmic Rays crashes require BFT (Byzantine Fault Tolerance) because it can send a 1 to a node and a 0 to another node, even if it is not malicious. For example, see [1]. Formally, CFT (Crash Fault Tolerance) does not handle this case.

- sirwhinesalot 3y agoAwesome paper you shared but I don't really see how my article is wrong from reading it? The focus of my article is on programmer-introduced faults not hardware failures.
- wslh 3y agoI didn't want to sound pedantic but for an audience that has specific knowledge about faults it is odd to avoid mentioning at least once the BFT kind of errors when you are mentioning cosmic rays. It is part of the field of fault tolerance and it is a different type of fault.
