An article here[0] includes some discussion of the cMix network model that Chaum designed, and which PrivaTegrity is based on.<p>I understand the idea that moving network path setup off of network user nodes and onto collection of hub nodes (network handlers) reduces the risk profile from a single user node being compromised.
