Okay, now I’m reading the white paper, and what in the world?
4. An Implementation Version for the Launch
For the initial launch of Phreeli, the determination was made to implement a simpler version of the full solution, namely privacy pass with user commitments instead of double privacy pass with user commitments. In this simpler version, an adapted privacy pass protocol with user commitments is run between the user service and the mixing service. The second run of privacy pass protocol between the mixing service and phone service is eliminated. An acceptable level of security and privacy is still achieved through this simpler version, because of the following reasons: (1) the first run of adapted privacy pass protocol between user service and mixing service (2) trust assumptions on the mixing service that maintains a mapping of Commit(iduser) and idphone (3) communication of the client or the user service with the phone service through the mixing service.
Are you telling me they designed “Double Blind Armadillo” and use “Double Blind Armadillo” in their marketing and at the very end of the text they reveal Phreeli is not double blind?
It’s certainly not “Double Privacy Pass” like the rest of the paper describes, at the very least. I don’t know if “Double Blind” has some specific meaning that might still apply to the implemented version?
