Of course! This is why it’ll outlast everything else.

Nostr separates three key things: identity, content, and client.

You can create your own identity (nsec/npub) offline. It’s owned by no one but you.

Your content lives on any number of relays. Relays have their own policies and compete for users.

You can take your identity and content with you to different clients. Client implementations compete on feature set.

This ecosystem affords permissionless innovation at multiple levels at all times. No other system has these properties. Any would be challenger has to face Nostr’s substantial first mover advantage.
