Someone tried to gotcha me with "how do we use bitcoin without electricity or internet" and I sent them nostr:npub1dergggklka99wwrs92yz8wdjs952h2ux2ha2ed598ngwu9w7a6fsh9xzpc 's article here where it talks about doing SHA256 by hand https://dergigi.com/2021/08/02/implications-of-outlawing-bitcoin/

Is it really so weird to think we could do bitcoin by hand on paper? Everything used to be that way. Just because math is involved for bitcoin doesn't make it less useful on paper. It actually makes it more useful because the math can be verified. I don't think it is likely that we ever need to do bitcoin by hand but it isn't unreasonable to think we could.

Imagine the difficulty adjustment after the power goes out tho 🤣
