I just registered a nickname on IRC and had to use a password to register it. Given that I've only used IRC, but never understood the P2P mechanics of it, I'd like to know:
Is the password I registered with Nickserv hashed, and replicated to all other nodes in the IRC network?
Is there a salt for that password? (what is it?)
Can anyone become a peer in IRC and see the hashed version of my password?
If none of the above applies, and Nickserv is centrally run, who runs it?
What other risks should I be aware of?
