Wondering who's going to build the first physical ecash wallet in cypherpunk history where all cryptographic operations happen on the device.
Discussion
Is that a little hint?😜
As long as it can handle QRs that don't spend exact 2^n amounts
Animated QRs are probably one way of solving that. The nice thing is that each token is independent of all the others so a scanning wallet could just "farm" all tokens presented in an animated QR one by one and then redeem them in one swoop.
Ben, who else?
