That’s interesting to think about… expiry QR code type, I think Calle has something like that with cashu
But I think you would always need at least the verifier online to query the network somehow
Network rollups meets Bluetooth mesh might offer something in the way of this if the wandering nodes could connect to a query hub that verifies on the network but at the root I don’t think there’s anyway way of “proving” without at least a central query hub
Yeh, I don't think it's actually possible to verify without access to the Internet.
I don't like the idea of expiring QR codes in the same way your $1 note doesn't expire.
The only way to do this, I think, would be to use a trusted third party that would print these notes with controls and forgery protection similar to most fiat note production.
I agree! Which actually could be something really viable for small villages on a long enough timeline
Imagine places with no access to banking only needing a small server hub with optimized hardware that can act as a mini paper mint (but with a hard money standard)
Ideally you’d want almost like a ombudsman style global technician team who deploys to do repairs to keep things honest
It’s a v cool idea for eventually
