yeah, fips is cool. it exactly fits in the network transport layer but implementing it would require installing a native app on mobile or a service on desktop. it's the right direction also.

pubky doesn't solve any problems that nostr isn't already better at solving, and mainline DHT network has some big problems. about the only thing that is innovative in pubky is the extension it makes for discovery of relays, which is questionable for privacy anyway, and with mainline DHT not having any kind of sybil protection means that state-level malicious actors can misdirect users relatively cheaply.
