Is there really a euro note that has those stained glass windows? Or is that wise rabbit's art? Good touch is the latter ; perfect example of inversion of meaning and value if the former.
In Paris there is Monnaie de Paris and Banque de France.
Then there are plenty of French banks. I'm not far from Lille in northern France. A nice city to visit too with old flanders Belgium style
I'm still trying to spec a true bitcoin bearer instrument as a physical L2/L3 with a hidden pre-image or time-locked transaction to guarantee x value (up to an expiration) with minimal trust and an easily verifiable serial number.
This would allow off-network physical bitcoin commerce. If anyone smarter than me likes this idea and wants to kick ideas, let me know. I have not seen a project like this but it seems possible.
