@johnhenry While I'm sure you're right, I'd like to hera what you consider an obvious flaw. In my perspective there are tons and tons of flaws, but none of them are very obvious considering the wide variety of usecases a blockchain can have.

For some scenarios blockchains are totally pointless, for some dangerous, for some just perfect. But if there's some all-encompassing superflaw that I don't know about, I'd love to hear about it.
