http://www.wired.com/2016/01/david-chaum-father-of-online-anonymity-plan-to-... Now Chaum has returned with his first online privacy invention in more than a decade. And with it, he wants to bring those crypto wars to an end... a new encryption scheme he calls PrivaTegrity ... based on cMix. Chaum wouldn't comment on whether the project... would be commercialized or run as a non-profit. Chaum is also building into PrivaTegrity another feature... a backdoor that allows anyone doing something "generally recognized as evil" to have their anonymity and privacy stripped altogether. Nine server council... a hoseablitly focus point similar to Tor dirauths. In any case... interesting. https://www.scribd.com/doc/294737065/cMix-Anonymization-by-High-Performance-...
