Hello,

I'm on the agenda for Tuesday's meeting to share a privacy-preserving proof of sct exclusion from a log (I think Eran alluded to this work in a message a while ago).

My posted slides will not include many words, so I wanted to share a link to the preprint of our academic paper on the subject in case anyone wants to read the details there. The paper is targeted at a somewhat different audience, but it can be found here: https://arxiv.org/abs/1703.02209

Thanks and looking forward to meeting you all next week!
