Yes, I'm working on software that will allow for verification of identity, among other things.
I don't call it proof-of-truth, because it doesn't guarantee truth on its own, it's just a tool to help (but it should be able to be about 100% correct for relatively simple stuff like identity).
We've been exploring the ideas around it for around two years now I guess, and we just finally started on the software itself. Here's more info on the overall goals of the project: https://wiki.peerverity.info/wiki/Main_Page
proof-of-truth was a joke on the proof of work, stake, brain :)
but it is not what i was thinking about.
Knowing nothing about how it could be done, using Hive for verification of authenticity of an video by connecting the video with the publisher (hive account) should be possible. i hate when i know but don't know the terminology, adding a hash? to a video and writing it on the chain to be able to verify that it was published by specific person.
Yes, that kind of thing is doable for sure. I'd just need to know the exact use case and I could make suggestions for how to do it.
