Nostr, but with something like an xpub rather than a single public key.
This way, you can partition your identity…imagine m/42’/0’/0 being for public access, m/42’/1’/0 only for the boys, m/42’/2’/0 for close friends/family.
Maybe using schnorr signatures so you can encrypt messages that many people can decrypt (if schnorr can do that sort of aggregation).
Maybe some method to support key / seed rotation too…
