i got a quick question about masternodes that keeps coming up while debating drk.

does each mn do the mixing alone or do they get mixed through all the mn's?
if the latter is true wouldn't someone need to control 100% of the mn's to track trans?
the reason i ask is because people are saying that the nsa can buy up a majority of the masternodes and track transactions. so if the nsa owned 80-90% of the mn's they could track 80-90% of the trans, is that right? thanks
