What exactly does a node do?
I get that it's a server, but in this situation what creates the need for the node? The new chat app itself I'm guessing requires at least one? Does each node & app include a Hive instance? If so then obviously there isn't a strong incentive to run the chat app server node for other people.
But I'd also assume Hive has many nodes and they are incentivized by earning Hive tokens and Hive cash?
