I'm having trouble seeing how you could have offline transactions that prevent doublespending. Could you expand on "nice physical gauge theory (allowing offline transactions)?"
If you have a good idea here, it might be possible to implement as a second layer on a chain with smart contracts.

I'm aware of approaches similar to this: https://gist.github.com/DavidBurkett/32e33835b03f9101666690b...
describing offline transactions.

That title might be misleading; the doc is just about generating transactions without the sender and recipient needing to engage in an interactive protocol. It doesn't address double spending.
+ offline transactions should be possible (allowing sync with the chain whenever), but also I do not think any have that.
A good crypto-currency is like cash, with a nice physical gauge theory (allowing offline transactions) guaranteeing security + any transaction processing rate.
Every single cryptocurrency now is still a research project first.
