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
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
experience
worse.
Thank you very much for your comments,

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

That all seems more complicated than it needs to be - the service you
are paying knows that it had received a payment from some public key Q
of payment differ from just proving
that a given transaction is in a given block (what SPV nodes take as proof
of payment today)?

Ok, this was a bad idea
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

Ok, this was a bad idea, since nodes would have to keep it in memory.
Please disregard that idea...

The idea is to simplify implementation. Existing software can be used
as is to sign and validate PoPs. But I do agree that it would be a
cleaner specification if we would make the PoP invalid as a
transaction. I'm open to changes here. I do like the idea to prepend a
constant string. But that

a PoP expects a PoP. (Again, thanks Martin Lie for making me think about
this.)
