Proof of Existence in the Blockchain with Tierion, RethinkDB, PubNub

I wrote another tutorial for the hack.guides() contest. This time it’s about building a Proof of Existence-like app with Tierion, RethinkDB, PubNub, and a Node.js stack.

You can read it here and the source code of the app is available on Github.

If you like it please give it a heart or a share, and if you have any questions or comments, please contact me.
