In 280 characters, name a non cryptocurrency use for blockchain technology AND explain why it's better than the existing way we do that thing today (for the latter, feel free to use more than one tweet). Seriously interested in REAL uses for blockchain tech.

Replace DNS with a blockchain. Distributed, verifiable. Some of the existing proposals are interesting if you ignore the obvious installed base issue.

Any particular proposal you would recommend I look at?

Here’s a peek at a working implementation hackernoon.com/hosting-a-dns…

Hosting a DNS domain on the blockchain | HackerNoon

tl;dr: If you go to docs.ens.domains, your DNS query was served by the Ethereum blockchain! It’s DNS, hosted on Ethereum, and you can use it for any DNS domain.

DNS was my first reaction, too. In practice it’ll never happen because today’s DNS isn’t quite bad enough to justify the transition cost. Blockchain-backed DNS would have to be a lot more awesomer to encourage the change.

DNSSEC is already fast, distributed, and has encryption finger prints. Blockchain would not help and would make DNS very slow.
