Didn't know that is at all possible, derive as in actually I can see npub and ed pubkey and verify they are related?
Either that works, or Nostr profiles include the ed25519 key, then use Pkarr to lookup the current relays if the user ever switched to an obscure or even single tenant relay.
Really bullish on this as I have stress tested as much as I could and didn't crack yet.
No, sadly you cant verify they are related. It requires a lookup, which is a chicken and egg problem. However there will be still some use cases. I'm hoping to normalize lookups in NosDAV. Until nostr keys are more widely adopted, that is.
I am curious about Webdav and reading about it, although I am thinking it might be so old that something new is needed.
Either way, I think it makes sense to use Ed225519 as the base of identity to leverage Bittorrent DHT as Pkarr does. It shouldn't be used often anyways.
