Block chain can at best give you chain-of-custody, but it can't help with the real problem - the original source. Trusting the original source requires, well, trust, so a block chain really adds very little to the solution.

In our implementation the source/creator of the media is verified as well. I think of our approach as "Twitter blue checkmark meets certificates" (sort of). Of course a user can always take media and re-upload it via any number of ways but they can't do so as any other user. One of our next steps is to have identity verification by way of social media accounts and Stripe identity or another identity verification platform.

The primary verification source is our API that interacts with a traditional data store. Blockchain only serves to add additional verification that we (or anyone else) isn't modifying or otherwise tampering with our verification record.
