Thank you for this video. I’ve been looking for info on cashu.
ESPECIALISTA! 🇧🇷
Thank you!
I don't understand how this system prevents double-spends. Because it seems like the server is just checking signatures. So what is preventing from the same valid signature being submitted twice? Can anyone explain?
The server marks the token spent when the unblinded signature is passed in, so it cannot be used again
