Repost because I'm so proud. Forbes article about Bitchat x Cashu:

"The Bitchat-plus-ecash model widens bitcoin’s surface area without tampering with its monetary policy, showing that hard money can be used in contexts where payment speed is important and internet connectivity may or may not be available."

I'm not clear on how ecash would work without an internet connection to have the mint sign the transactions / prevent double spend 🤔

I'm so new to this though

you have the right idea. sending ecash tokens offline does not prevent double spending. it's just as unsafe as getting a bad paper check.

any time it looks like there is a hole in ecash where you are not safe or something bad could happen to you, just assume that hole is real. ecash is basically an overhyped toy that requires too much trust.

I like the anonymity/ privacy aspect of it. There's a lot of value in that, although you do have to trust the mint. But after hearing so much talk about it I thought someone had come up with a digital, offline bearer instrument. my hopes were too high
