Almost all of these would have been possible without a blockchain. Either through a web of trust or even simple cryptographically signed messages with timestamps stored in a normal DB. Some of these aren't even "real world use cases" like Hawaii trying to boost tourism by something-something blockchain. Civil is a notable exception, though I'm not unconvinced that it couldn't be done without one. In the end though, i…

That is my biggest excitement. Blockchain is something the CEO wants to say they are doing at the board meeting. If this enables an end around so that we get more transparent healthcare or government or ...., they I'm fully for that.

Ripple is kinda an exception as well, it allows the bank to crowdsource their nostro/vostro accounts.

That's the part that I can never understand with blockchain applications. Blockchain technology is excellent at maintaining a ledger or variables of information within the blockchain - these processes are completely trustless due to the properties of the blockchain. The problem is getting that information INTO the blockchain. This part DOES require trust and all those nasty things people say blockchain solves. I think it's called the oracle problem?

Namecoin is the best example of a real world use case, a proper replacement of a DNS with no central authority. This is clearly one which is very difficult to replicate reliably without a blockchain.

Even if blockchain DNS systems were production quality - which they're far from - why is a 'central authority' inherently bad? The entirety of cloud computing, and the modern internet, is based on the pretense of giving your entire infrastructure to a centralized authority. "Oh, but what if your centralized cloud provider is actually evil and incompetent", the free markets allow you to change providers until you have a provider with absolute highest quality.

You can't switch ICANN... Unless you count onion addresses but then Namecoin is very similar.
