The bitcoin system right now will work in the same way but different orientation that the old Silk Road market did as the previous market did not mix coins, it simply made it impossible for X to determine who Y is so as a buyer you could not determine which withdrawal belonged to which vendor and which deposit belongs to which buyer. The idea that Silk Road mixed their coins in comparison to popular perception is incorrect, it did not protect you from an adversary being able to determine you used Silk Road if you don't take additional measures just as our temporary measure will be. Our mixing system which will be implemented only days after launch will be very sophisticated and is designed to stifle adversaries from being able to determine which action is a withdrawal, which is a deposit or that the funds are even part of Silk Road and we have somebody who has already helped us solve how to do this as he was one of the best minds for the job in the dark net.
