Comment by quietbritishjim

This sort of comment is exactly why articles like this will never result in constructive discussion on HN (or elsewhere). It doesn't address any of the comments in the article and doesn't even give any concrete examples of its point (in this case the "utility to society"). Don't take this personally, crypto always results in comments like this. It just turns into a vacuous slinging match. I tend to flag the articles about cryptocurrency/blockchain unless they contain some actually new technical innovation.
