Are you working on this? According to Claude, Non-Interactive Group Membership Proofs can be done on nostr. Alice can independently create a proof that "one of Alice, Bob, or Carol wrote this".
I was researching this field a year ago without Claude in an attempt to get experts comment on products for Walletscrutiny. As the experts all have their own wallet products, it's delicate to comment on the short-comings of other products but if they could author a note that originated from a set of wallet providers, it would have the weight of a wallet provider without the repercussions of talking down on their competitor. Get their wisdom out there without them getting punished for sharing it.
