programming

In regular programming, zero is false and anything else is true.

In ZK cryptography, zero is true and anything else is false.

Hmm. Isn’t this also the case in Hoon, the urbit language? Though iirc that was just an arbitrary design flex with no reasoning behind it.

It is, they call it a "loobean" instead of a "boolean."

Nice. I didn't know this word.

It is also the convention for the return code of a correct program execution.
And so it is for me THE good convention in shell scripts (sh, bash, etc.)
