[jjeffryes]

Description

This will demonstrate it is possible to create a purchase and send it to a seller's node from inside a browser client.

Questions

Deliverables

Assumptions

• The POC can have a hard-coded buyer key it uses for signing, or it can derive that key from a seed as in Build an Identity Prototype #4

Create and Send a Purchase

• There should be an input field for the url to a listing. The listing doesn't need to be shown, all that is needed is the ability to enter a listing to be purchased.
• When a purchase button is clicked, the data for the listing in the listing input will be loaded and used to send a purchase message to a messaging server (see Build Advanced Messaging Proof Of Concept #3).
• The purchase message will need to be signed with the buyer's key.
• QUESTION: What other data is needed to create multisig transactions for offline and moderated purchases?

Make a Payment

• When a purchase is created, it should be possible to pay for it with an external wallet.
• A payment address will need to be created and displayed, along with a payment amount.

Monitor the Payment

• Once a payment is made, it should be monitored for confirmation.
  • This will require the UXTOs, they should be available when the payment information is created?
  • It is ok to use a standard blockchain explorer for this, unless OB1 insight servers are ready for use.
• Once the payment is confirmed, a confirmation message should be displayed on-screen.
