I'm surprised blockchains are still being hyped even though they have practically no useful applications for business. Of all buzzwords, blockchain must surely have the worst hype-to-usefulness ratio of all-time. Having said that, even though paying for a digital signature on a blockchain is absolutely ridiculous in my opinion, if people know what they're buying then I don't really care what they choose to waste their money on.
