Isn't it possible to implement ecash in a way to break this? How do you know if a custodial wallet implements it like that or not?

Thats a powerful feature that sometimes people refuse to see

Develop this to me as if I am Peter McCormack pls

There is a mint and there is a wallet. If you use an open source wallet you trust that follows the cashu protocol, you know the mint you're interacting with is following the rules of the protocol.

If you use a proprietary wallet with mint, you can't know what's behind.

Right nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg ?

Since I watched your interview with Peter McCormack you are always in my radar. I also studied Physics with MS but stopped before going to PhD route so I really admire you. But even after watching the show it is not clear for me how to use Ecash, cashu etc... I got the same problem with Obi for example he explained but didin't register with me =ı

Anyway I just wanted to pay my respects =)

Just tried enuts. Looks good! Can't wait to see what people do with it
