Not sure if I understood the question correctly but are you asking if a private (small) retailer can use the platform without any problems to sell his goods?
i think that's what they're trying to do, partner with alot of suppliers small and large.
Vanig are aiming to operate in a similar fashion to Amazon, EBay and other popular E-Commerce websites/Supply chains. This means having a mixture of large retailers and smaller partners. They mention it in their whitepaper.
Also do you know that sellers will receive $1 worth of Vanig tokens per verified product listing, $6 worth of Vanig tokens after completing 5 sales successfully. Pretty cool incentives for sellers to use the Vanig platform, eBay & Amazon will CHARGE you to list products on their site, Vanig want to PAY you to do it.
Wow these are nice incentives man, am totally sold and i can imagine merchants will feel the same. With this incentives i'm confident they will get lots of retailers on board in no time, getting paid to verify your product is cool.
This is not a fashion similar to eBay no Amazon, this is by my judgment an improved eBay fashion
you already get a cut just for listing, that's already something especially for countries where $1 means a lot
