Yes. But for nostr.
Awesome, but ...for what purpose would you want someone to approve a note? (Or is this for a developer project?)
Imagine you're a chess club. You want an official nostr account for the club. You decide three of the flue board members need to approve of things. These thins could be notes. It's a shared Npub, so the notes view is the same account. Just need multiple people (or one!) people to approve.
