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?
