Hmmm.. I don't understand much of what that says. It seems that the bartering system basically means, between participants: I will store some of your data and you will store some of my data. And I will provide bandwidth for your data and vice versa. Both nodes agree to this deal. That way, nodes establish long-term relationships exchanging storage and bandwidth. Is that correct?

But, is there a way to buy/sell storage or bandwidth, without bartering? Could there be an economic incentive to run large-scale nodes providing service for buying customers?
