I am trying to understand how does a new Tor relay begins its life. I understand that the relay will form server descriptors based on its config and send them to all the known directory authorities as described in Tor directory protocol v3.
What happens after that and before the relay starts to receive connections from other relays or clients? I would appreciate an explanation or/and a link to the relevant point in documentation. Does directory authority somehow responds to the relays descriptor or maybe it checks it before making it available to the network?
