I really feel like I'm missing something about Cashu. nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg calls it digital cash, but you are reliant on a bank (mint) to cash out. They say it works offline, but it doesn't really because it doesn't prevent double-spending offline. This makes it a glorified IOU tracker, right?
Privacy-preserving IOU tracker is cool, and a network of banks that used them would be even cooler, but calling it offline digital cash seems totally disingenuous to me. Tell me why I'm wrong?

bro has no idea ecash is 30 yrs older than bitcoin and literally coined the term digital cash
oh and it works offline. how would you call digital cash that works offline without being "disingenuous"?
this post reads to me like a "it feels wrong" without any substance. let me know when you have a specific question.
I do know some of the history of ecash, that doesn't mean calling it "cash" is good branding.
So here's my specific question: Is it possible for me double spend cashu tokens that I gave someone while offline?
no, the receiver reissues the token when they receive it preventing you from double spending
Can you explain to me (or point me to the details) of how the tokens are reissued? I thought to swap you have to connect to the mint? Or is reissuing different from swapping?
yes the receiver has to be online to prevent the double spend of the Bitcoin iou. but we're not even talking about Bitcoin at this point, which is why it's misleading.
Ok, I kinda wanted to be wrong about this but that's what I understood from the protocol docs. I thought calle was just overselling it but their messages in this thread feel downright deceptive.
