That does require trusting the third party not to later tamper with the payment request, though. (I'm assuming that a signed payment request is not always going to be all that useful in the case of private individuals, even assuming the payee is willing to sign up for one.) > Likewise, I could attach a payment request to an email and send it to you, > and now you can pay me whenever you want forever. That certainly sounds like a plausible use case. You do still have the problem that e-mail is an insecure channel, but it's no worse than exchanging Bitcoin addreses over e-mail as things stand at the moment. roy
