Something that worries me about Nostr is the fact that someone can grab your private key in some insidious way and then that's the ballgame on your account. Is there a way to modify the protocol so that we can issue and control multiple "secret keys" at some sort of clearinghouse that we can then use for various applications/clients etc, so that we only see the secret key the moment it's created, but then giving us the long term ability to roll or cancel the keys as needed. nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6? Granted the account at the clearinghouse could just as easily be hacked but at least it becomes just one single place to organize the user's interface with the Nostr ecosystem.
