Your NIP-05 serves as a user-friendly identifier for your identity, similar in appearance to an email
address,
for instance: service@nostrich.house. This identifier simplifies the process of locating your profile on
Nostr.
What would be your desired name at nostrich.house and what is your hex pubkey (or npub)?
Why does it cost sats
Because it's so very easy to spam on the Nostr. We need a way to distinguish serious posts from
mass spam. One good indicator is a non-free nip05 address. Minimum here is 500 sats for 500 hours
usage. That's ridiculous little money but if you want to pay for a million spam-bots, it's not so
cheap.
You can get a nostr address
also on several other sites or set it up easy on your
own domain.
