Actually one thing I noticed is that small delay in confirmation of receipt. This can give us the opportunity to get a full acceptance flow for online payments.
So you send me ecash and from your end it is done, but for me, I haven't really accepted it yet. I trade it for a new ecash and if it works, I accept. If it fails, or if I don't want to trust that mint, I reject. I could also reject it maliciously of course.
If I report the payment as failed, then you can trade the ecash for a new one and if it fails, then there's a problem. But in most cases you just take back the funds and payment is cancelled/rejected.
The problem case is interesting. Without p2pk and a timeout, there is no atomic payment and even with, there is no proof of payment like we have on lightning afaik.
Are there any protocols or flows to address them?
