Just listened to @calle and @ODELL talking about cashu, awesome rip. Calle very good at explaining ecash clearly and honest about tradeoffs.
@calle - not sure if you will see this but a quick question: How would an honest mint unwind/close? Would they basically need to wait for every user to send their ecash out the mint to another mint or lightning invoice? Or can they just decide to move everyoneβs ecash themselves to a different mint and just close theirs?
