[2022] How does PvP work in Ashes

I skimmed through https://ashesofcreation.wiki/PvP page, but can't seem to find an answer to how it works. In Guild Wars there's not really open world PvP but it's server against server in WvW. In ESO it's alliance vs alliance vs alliance in a huge map that's about the 1/10 of the game. So how does PvP work in Ashes. Is it race vs race? Do you have to be a part of a certain node alliance to be able to attack another node. A little confused.
