Am very proud of this PROOFOFYOU startup that is inspired by by research publications. Would be nice if they evolve to the level of the ideas that are in my latest accepted IST journal paper. Here is a preprint version of the journal paper and hopefully the startup will eventually be able to embrace many ideas from my publications. Here is again a more high-level video about smart contracts from a recent lecture in St. Petersburg that I gave at the Open University event. More related information and a link to a second recent St.Petersburg lecture is available on my previous blog post.
