I'm not tech savvy. Does this mean you can get domains for free? You don't have to go through domain registrars?
like nsec and npub on Nostr, yes. but we have to point our address resolvers to a special DNS server. But devs could include it in their apps, so we users do not need to mess with our DNS settings. But maybe in future some public DNS servers support pkdns.
I did orginally say it was for free, but nuh corrected me. Yes there is a tiny 1kb storage cost which I estimated to be 1/1,000,000 of a satoshi or a "microsat". For 1 satoshi we could get everyone on nostr a domain :)
