“Private groups” are on a lot of people’s mind. (As a serious real world use case of nostr) I’ve reviewed a couple proposed NIP architectures that try to accomplish this : gift wrap using either individual or shared keys, depending on “size” of group.
IMHO, having two “kinds” of groups will be a UX disaster.
As a nostr noob, I don’t expect my ideas are all that great. But I did read ALL the documentation of these proposed NIPS and might have found a simple and overlooked solution. (Maybe the start of one…)
A “Gift Bag” type of “Gift Wrap”
