We need to develop a system of parent and child keys on #Nostr that can be managed by an admin key. This admin key could potentially utilize multi-signature functionality for added security.

This system would serve two important purposes:

1. It would eliminate the need to create a new npub (public key) in case of a compromised key.

2. It would be particularly beneficial for businesses, especially those that outsource their social media management.

Many businesses hire external individuals or agencies to manage their social media accounts. If any of these individuals compromise the key, either accidentally or intentionally, or attempt to retaliate against their former employer (which has been known to happen), the admin key or keys could lock the child keys of those employees when they no longer require access to the account.

It's unreasonable for businesses to have to navigate this vulnerability when the consequence of failure is having to start a new npub. A hierarchical key system would provide a much-needed solution to this problem.
