How to imagine a real Substrate application?
I am trying to make an application, where you can trade your own product. You can advertise product, buy, list, see your earlier purchases, etc...
If I start a substrate node on local, I am able to connect to it with my own front-end and place products on chain. But it is local... What about a real world application? Every users have to start their own substrate node, and after that they have to join to it with my front-end? I think it is a little complicated processing.
Please, somebody clear it to me.
