Unfortunately, even if we can pull it off "cryptographically signing a video" doesn't "solve" the problem. How would that verification be presented to a user? How/why would it influence their beliefs/actions? (As mentioned elsewhere in this thread, I go into a bit more detail here: https://www.washingtonpost.com/news/theworldpost/wp/2018/02/22/digital-reality/ https://www.washingtonpost.com/news/theworldpost/wp/2018/02/... ) Will try to write a HN friendly tldr/update soon.
