I heard mention of this recently too. Might have been nostr:npub1trr5r2nrpsk6xkjk5a7p6pfcryyt6yzsflwjmz6r7uj7lfkjxxtq78hdpu on one of the Cheat Code event recordings? My memory was just conceptual though, rather than any actual technical implementation. Would be interesting if something actually is in the works.

I read a technical document about it and someone had worked a lot of it out... but it wasn't done.
Glad I'm not the only one who has heard of this and I didn't imagine it hahah
