I am looking forward to details of forging as i want to setup a node
actually all info on Forging is in YP. Publishing the code soon and starting tests.
In basic, it will start with Peers as they are the cheapest and easiest to set up. Rewards will be distributed only to Peers at the start. And then new roles will be added.
So $40 a month VPS would do well. But you will be able to test soon
