Multisig Nostr client I'd like to see:
FROST-based k-of-n group account on Nostr with PSNN (partially signed Nostr notes).
I think you could potentially lose up to k-1 keys and still have a Nostr account that the attacker doesn't know the aggregated pubkey to.
Sounds good! But wait, what?
What happens when you need to do a key replacement?
You’d have to generate new pub keys which means a new “account” and social graph AFAIK
Not sure if there have been any other PRs on the subject, NIP-41 being the last one I skimmed
