I don't have any code to show you- if that is what you can.. I am trying to find out what options there are for replacing marketplace payment functionality< as commonly provided by Paypal, with blockchain technology: On a Marketplace-type website, when a customer buys an item belonging to one of the sellers on the marketplace, a small percentage of that payment goes to the Marketplace.itself as payment for the seller being able to list their item on the marketplace. Can payments be arranged in this way using the QR code? and, if they can’t, Can something called a Smart Contract be used to arrange payments so that a small percentage of the payment to the seller goes to the Marketplace? If the answer to the second question is “Yes”, is a smart contract something I can write myself or do I need someone professional to write it?
I noticed it a long time ago, certain posts do not show (and the profile is either hidden or shows incorrectly). I am guessing it's something within the post (probably a code or tags) that makes it happen.
