Have you read the PCC whitepapers? Are you saying the user-facing verification methods in them are insufficient, or vulnerable, or just false?

The previous argument was wrong and imprecise, as it could be used against any modern technology, none of which can be fully understood by a user, in the sense that any vulnerability would be completely invisible.

It’s clear they have made a very intelligent approach to this system.
