You don’t “need” to be verified, it’s just nice to be able to prove you’re a real account vs one controlled by an impersonator, bot, etc.

Ok. Got that. Why doesn't do PGP the job?
This is a Nostr specific verification and will show in clients
As with nearly all things PGP, nobody bothers to use it. Plus, PGP verification isn’t part of any nostr account verification mechanism I’m aware of? See the NIP05 link I posted, good jumping off point to learn more about the protocol.
This is also why self hosting the NIP5 is important if you’re a public figure. If you have a website that people know is in your control, then it makes sense to use it for your Nostr address
But no, it’s not “needed” per se
I just did it as a learning exercise
