Mainline has many bootstrap vectors, the three famous domains are convenience, not single points of failure.
PKARR provides signed, multi-endpoint records. Nostr relies on trusting third-party relays to actually store and serve your events.
Pubky’s protocol & apps are already open, the polished new app will open once it exists.
So your claims that PKARR “isn’t more censorship-resistant” or “isn’t really open” are disproven.
Thanks for playing.
