I see the confusion. 1. Anonymity isn't a goal, persay. Everything you're talking about, in terms of "public incompetence" is true immediately once you post anything online. It's only a matter of time. Personally I'd argue that people who are actively seeking tutoring would be more sought after, but that's another story. Not to mention most of the things you're mentioning could be accounted for during implementation. 2. In your example, if you tutor Thomas in basic math, you would receive 20 Tutorbucks in exchange for said knowledge to be available to everyone, hence the exchange being public (furthermore, a third party would have to spend their Tutorbucks to actually view said session, perhaps). If, you wanted Jenny then to help you with Spring's authentication you could then give her the 20 Tutorbucks as opposed to the system giving it to you, and then it could be private, though that's not how I originally conceived it. As for the submission question -- how do you guarantee to all participants that data isn't changed without blockchain?
