New v4 ecash encoding format is more efficient, so it fits more ecash into standard QR code.

I prioritize that over the animated codes, because they are much less interoperable (can't be scanned easily with standard readers etc).

Will see how far we can get with that, if there will be the need I'll implement animated ones. 

 Good strategy indeed 🔥🚀 when is the roll out of the V4 ecash encoding format then ? ;-)
Thanks so much for bearing with me, it s fun testing this... I understood it is enhanced privacy for lightning fast payments, isn't it? Could I run my own cashu mint on umbrel? Would that be technically possible? 

 v4 format is now default in new Minibits release.

To run your owm mint, check cashubtc/nutshell om github.
