I wrote a simple nostr relay that can be accessed via a pkdns domain. It automatically creates a pkarr domain and publishes it on the DHT. The goal is to be able to setup a relay without having to rely on ICANN which is a corrupt system. The relay's websocket URL looks something like this: wss://9zbr9pp1pkpqdwugzny9o8uuo9yjenc1dxt6gwpwaqxg8qg5omxo I'm a beginner in Rust but it runs :)
pkdns is an amazing piece of software. What is pkdns ? "A DNS server providing self-sovereign and censorship-resistant domain names. It resolves records hosted on the Mainline DHT, the biggest DHT on the planet with ~15M nodes that services torrents since 15 years." And it can forward ICANN queries to your regular DNS server !
