By design, if the three or six nodes that you used compare notes, they can tell who you were talking to. That seems roughly the same as breaking a key into 6 parts and giving it to 6 different parties. I think the government would be able to go to each party and ask for their part, then put them together. Therefore, there&#x27;s no expectation of privacy.<p>What actually happened is the researchers found a way to bypass the middle guy and reconstruct the info just from the two ends. That&#x27;s still just comparing notes, but from fewer people.
