I have a crazy idea about "Lightning Voucher" (I'd rather call it Lightning Cash) Thats a paper money build in Lightning Network via LNURL Its elegant synthesis formula is as follows: Banknote+LN = LightningVoucher
You could scan the QR code from the LightningVoucher to recieve the Sats! So i could buy a beer with LightningVoucher if the bar accpet bitcoin lightning network! It will help more muggles(no offense) to know and use the real bitcoin and i'm willing to sponsor a campaign about giving away LightningVouchers! What do you think about that? :p
