So it sounds like everyone(?) is behind this "umbrella" of protection from a hub. Who owns a hub? Is the forging based then on the "hub level" IP? Do people choose which hub to be a part of or is it proximity based or...? Very new to this, so hope these aren't old questions (I'm familiar with traditional cryptos, just not his one).
Anyone who can afford to pay for antiDDoS protection can own a hub. People do choose hub(s) to lease forging power to. To keep the network as decentralized as possible they could split forging power to 100 parts and lease to 100 different hubs.
