I have a suggestion for a new protocol. Maybe something similar already exists, but I do not know. The essence is as follows. Organizations and small companies may need to maintain a Nostr account. But it is dangerous to trust the key to employees - it can easily leak. You can make a similarity of the Nostr Wallet Connect protocol, but a server will work, the purpose of which is to store the key from the company's account, accept applications for signing notes from trusted clients (via the dedicated Nostr relay) who own a secret that can be revoked at any time (as in NWC). That is, if an employee is assigned to maintain an account, he receives a new secret, after which his client Nostr works the same way as with the original company account, but all notes are sent to the relay, listened to by the company with the key from Nostr. If the messages are signed with a valid employee key, then the note sent by them is unpacked from the padding field, then signed as the original with the company's Nostr key and sent to the network. Thus, the company will have an official account in Nostr, which can be accompanied even by several employees, and there will be a minimal risk that the account will be subjected to constant insider hacking.
