Can you please explain what's privacy-preserving about having to reveal IP addresses to a centralised mint every single transaction... while still being able to get rugged for 100% of the value.
The payer doesn't have a mint interaction while paying, so as the payer, you're not talking to the mint for each transaction.
You can use VPNs or Tor if you want to hide your IP.
We're also integrating OHTTP into the Cashu protocol:
Cashu is awesome.
David Chaum would be pleased to see what you're done.
I couldn't find it, but he made a cartoon explanation of an IRL scratch off card that could be used as physical ecash. It had multiple denominations on a single card, and you scratch off a few QR codes in different denominations to reveal the payment amounts for scanning by the merchant.
Maybe you could team up with Madex or another artist to design a promotional scratch off card for conferences or IRL orange pilling kits.
For the payer to receive the e-cash in the first place, they must expose their IP to the same mint that the payee uses to redeem the e-cash.
Using Tor or a VPN does very little to obfuscate actors with a whole network topography view.
I always wonder why but looks like people are ready to trust all their data and money to one guy in a garage for privacy 👀🤔
