Let me start off by saying that we have been using the API access of Wordproof because our website does not use Wordpress or any other common CMS platform.

Wordproof is one of those product that only does one thing and does it right: it timestamps your content.

The good thing with the API use of this, is that we have total freedom on the content we want to timestamp and the format of it.

A couple of things to pay attention to:
- most of the content to get started is videos, so don't expect to find many tutorials in written form
- once you pick a blockchain (ethereum vs eos) you are stuck with it, so make the right choice :D
- wordpress integration seems very easy, api integration doesn't have great documentation but if you are a developer you'll find your way.

Overall, a great project deserving a great review.
