I keep hearing this, that blockchain is, of itself, an interesting solution to problems we are having. But I don't see any evidence of it. I tend to agree with the author, that blockchain doesn't solve any problems that can't be solved better by a database. So far, no-one has come up with a problem outside of cryptocurrency that actually needs a blockchain to solve it. The only evidence of any innovation that I see (and I'm not that into the space, so I'm probably missing things) is scammers learning how to scam better. Given that currency is actually this great use case for blockchain, can we solve the outstanding issues for that? Bitcoin has some serious problems with transaction speed that stopped it from being used as an actual currency. Can we solve those yet? Can you actually buy a coffee with a cryptocurrency without having to wait 10 minutes for the block to resolve and confirm? If so, can we actually use that as a currency?
