“What is NIP-05?
NIP-05 is a verification method for your Nostr account across all clients. Think of it as the blue checkmark on Twitter or Instagram, but instead of meeting Twitter and later Instagram’s requirements to be verified, you can simply do it yourself, and Nostr clients will respect it.”
