how will the marketplace offers be stored, what about the images/media and other info, how are they stored? I'm assuming your hosting each marketplace via the simple http server you have in your code? How is it decentralized hosting, that i thought was claimed somewhere about this coin?
As I understand the Shadow communication system, all the content for the platform exists in each wallet. That's the way the Shadowchat works- everybody on the network gets the message, only the intended recipient can read it or is alerted to it.
This may eventually create a bit of of bloat and I can foresee the wallet and its content getting very large after a while, but there is no free lunch.
