I found What can blockchain do that normal databases systems won't?. The text of the question asks about blockchain advantages and real life use cases outside of cryptocurrencies.
I would like the answer this question, but I can't see how to do it and stay on topic. Obviously, the answers wouldn't say anything about bitcoin because bitcoin is entirely designed from the ground up to support a cryptocurrency use case.
If questions about non-bitcoin blockchains are off topic, how is this on topic?
(For the record, I strongly opposed the change in scope for bitcoin.SE precisely because it would make it impossible to have these kinds of discussions.)
