I don't think that video is the flex that you think it is. Granted this is well outside of my wheelhouse, but even the guy in the video admits multiple times that he's not really finding that much information. He also admits that this was from before. Whatever new XMR implementation dandelion is. I would assume that would make it even more difficult. That guy did not do a very good job of selling its ability to track XMR

I'm just trying to learn but that video is kind of a good commercial for XMR and is far from a nail in the coffin
