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.<p>Civil is a notable exception, though I'm not unconvinced that it couldn't be done without one.<p>In the end though, if blockchain is sexier / more marketable than signing messages with GPG or SSH keys then fine. At least we're getting higher integrity guarantees on data one way or another.
About that fine art project they mention (it doesn't work): <a href="https://twitter.com/edent/status/1006248586395508737" rel="nofollow">https://twitter.com/edent/status/1006248586395508737</a><p>> I don't understand the blockchain hype. A startup has certified my artwork & placed their verification on the bitcoin blockchain. Now art dealers & auctioneers can feel secure that I am the original artist. One small problem… I am not Leonardo da Vinci! <a href="https://www.verisart.com/works/23f2c64a-08c6-4a42-8013-84ac8422dffb" rel="nofollow">https://www.verisart.com/works/23f2c64a-08c6-4a42-8013-84ac8...</a> …
This is just a list of current ideas (mostly) and implementations using blockchain. Calling it a list of "real world use case" is far fetched. We have yet to see whether it actually works.
> Rare Species Protection<p>I can't think of a part of meatspace more removed from the special properties of a blockchain. That's honestly dumber than blockchain iced tea or KodakCoin.
Even if these were all full-fledged businesses/ventures/operations -- most of them don't answer what is, to me, the real question of the day: in what applications are the benefits of blockchain an actual imperative to the use case? Most of these don't seem to clear that hurdle.
Seems like most of these can be done without blockchain. Some are not even 'real world' at this point, but just experimenting. As others have pointed out, when in doubt - 'do you need a blockchain? no'. Overhyping them for use cases where they are not needed will have a negative effect on trying to get support for the places where they might actually be useful.
Blockchain is a collection of technologies rather than a single one. Like a car. Yes, one can claim their motorboat runs on “car technology” because of the internal combustion engine. But it would be strange to do so.
Real world use cases?<p>is developing a, that would use, will be using, it is possible to, as it seeks to, is building, which will be, seeking a way, has been experimenting, ...<p>Sounds more like a maybe future fantasy world.
I'm shocked IOTA isn't on this list.<p>Companies like Bosch and Fujitsu are already creating uses for it in IoT.<p>There're already a few IOTA-powered electric vehicle charging stations in Europe. It's instant and fee-free, with very little overhead (no power consumption problem).<p>Since it cannot be mined via PoW, there are already efforts to create "mining pools" were universities can rent CPU/GPU power from "miners" using IOTA, that way miners are performing valuable computations rather than just a bunch of redundant math.
