Still don't get how that works or what's even possible with that.
Can you, for example, have a quorum of keys that control one nsec and switch them out for an entirely different set of keys?
Discussion
It's like creating a public key with multiple private keys, like multisig creates an single address by multiple pubkey, or Shamir creates a single seckey from multiple shares.
I am still studying this, but since it depends on schnorr signature, I think it will be difficult with the current nostr key (though proto NIP-95 exists already). it will have to start from a new key, won't it?
can't you do something like musig with schnorr quite easily?
