I guess it depends on what you're recording, but even if you don't save the audio, or the camera recordings, information can still leak. Am I sharing my screen with my tutor? Great; my browser bookmark bar is visible, and possibly my URL history if I start typing something in. Oh, look - my Gmail tab shows my entire full name. My anonymity is blown before the second frame of the video loads.

I guess I don't understand the system. I thought that if I tutor Thomas in some basic mathematics, I earn 20 Tutorbucks. I can then spend those 20 Tutorbucks by paying Jenny to help me understand how Spring's authentication system works. It doesn't really make sense to do tutor exchanges - what am I going to ask Thomas for help with?

In any case, it seems like the answer to the submission's question in your case is a resounding no. There's nothing a blockchain brings to the table.
