The bit about using unstoppable domains is the hardest part. Since you need some sort of browser add-on in most cases to access them. if browsers just knew how to read the polygon chain like they know how to use DNS would be best 

 Yeah, the easier it is the better.  Brave and Oprah have native support.  But you do have to enable it 

 the devs could create Nostr accounts, publish their public keys and just have the browsers read nostr relays i guess. that may be an option.
