Sovereign NPUB: One identity, forever. Controlled by many, owned by you.
The problem: Your Nostr identity IS your private key. Lose it → gone. Compromised → hijacked. No recovery. No rotation. No delegation.
Our solution: FROST threshold signatures. Split the key into shares. 2-of-3 to sign. Nobody holds the full secret — ever.
The magic: Reshare to change who controls the key (add bots, remove compromised shares, change thresholds) — the NPUB never changes.
Every control change is a NIP-78 event, timestamped in Bitcoin via NIP-03. Recovery from 24 words on paper. Policy engine governs what agents can sign autonomously.
BIP-340 compatible. Every Nostr client already verifies it. No protocol changes needed.
