no.
I'm saying the person paying you knows there's a "true" output on the chain and which one it is.
because they spent it to your key.
but if the output appears again on the chain they have no way of knowing if its a true spend of not.
so no surveillance happens.
but they can look at it and wonder about it. it is greater than zero information
maybe they're Chainanalysis and they have other data to correlate.
ideally we would reveal zero information right? the plan is to move to a system than reveals much less about the payee.
but this is just blockchain stuff, none of it is news.
