Hi Jorge,
I don't think I understand the question. Proof of Payment is used to prove
that you have the credentials needed for a certain transaction. It does not
care where in the blockchain the transaction is. Or if it's in the
blockchain at all.

So at the low level, how does a "proof of
So at the low level, how does a "proof of payment" differ from just proving
that a given transaction is in a given block (what SPV nodes take as proof
of payment today)?

"Or a really high lock_time, but it would not make it invalid, just
delayed."
Ok, this was a bad idea, since nodes would have to keep it in memory.
Please disregard that idea...

Hi again
I've built a proof-of-concept for Proof of Payment. It's available at
http://www.rosenbaum.se:8080. The site contains links to the source code
for both the server and a Mycelium fork as well as pre-built apk:s.
I'm still very interested in feedback on this, so please let me know what
you

Is it? I'm assuming TLS is being used here. And the hotel server also has a
copy of the PaymentRequest, as the hotel actually issued it and that's how
they're deciding the receipt is valid.
Hi
No I don't agree with the analysis.
Yes, the PaymentRequest can be stored with the same security as the private
keys are stored. The big difference is that the keys never leave the
wallet. As soon as that PaymentRequest leaves the wallet on its way to the
hotel server, it is up for grabs which
Hi Kalle,
I think you're thinking along the right lines, but I am skeptical that this
protocol adds much. A saved payment request is meant to be unique per
transaction e.g. because the destination address is unique for that payment
(for privacy reasons). Where would you store the signed payment re
