I read this article and I understand how a node can become a entry guard but I didn't found documentation about how a node become a exit node?
Where I can found documentations or articles similar to the article about lifecycle of a new node?
I check this post. It says for the exit node:
A router is called an 'Exit’ iff it allows exits to at least two of the ports 80, 443, and 6667 and allows exits to at least one /8 address space.
That means a new node configure it's machine with these ports open and enough adress, it's become automatically a exit node?
