Hi all!
As indicated in my first email regarding Proof of Payment (Mars 13, subject
Proof of Payment), I would like to BIP it. I have two proposals:
* PoP datastructure and process:

* btcpop: URI scheme:
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
Forget it, sorry, I misunderstood the proposal entirely, re-reading
with more care...

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)?

Some more use cases might be:
Waiting in comfort:
- Send a payment ahead of time, then wander over and collect the goods
after X confirmations.
Authorized pickup :
- Hot wallet software used by related people could facilitate the use
of 1 of N multisig funds. Any one of the N wallets
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...

Thank you very much for your comments. See my answers inline:

Hej, Kalle.
I love the idea of standardised PoPs, including a protocol for
requesting/sending them as an extension of BIP-70.
Me too!

Actually, the security of the PaymetRequest is pretty much out of your
control as soon as the PaymentRequest is created on the server. You have no
idea what the hotel does with it. Also if it's stored in the hotel server I
have to trust the hotel to keep it safe for me.
Well, yes. But if

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. So
Hi all,
I've been thinking about how a person can prove that she has made a
payment. I came up with an idea I call Proof of Payment (PoP) and I would
highly appreciate your comments. Has something like this been discussed
somewhere before?

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
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
