I have to agree that for the most part we haven't seen any real products come out of the crypto space. And there's a lot of chaff. It actually blows me away sometimes how many icos there are
For one thing, the blockchain doesn't provide tamper proof asset registries because the blockchain can be forked (see the DAO fiasco for proof).
Second "temper proof asset registeries" aren't actually a problem that really needs to be solved. The hard part of any registry is making sure the data that goes in is valid.... and that is a meatspace warm-fuzzy-human problem, not a technical problem.
I don't believe in the saying that you need a problem to be solved. For sure the country I live in now cannot lookup easily what other real estate properties I own in every part of the world. All governments would need to select a distributed database and encode everything on it. Well this is now called Ethereum or insert your favorite platform here and they will develop on it because the technology makes it easy.
Sooo innovative...
