How to use Proof of Data and Jupiter Upload (IPFS) to Archive a PDF

Say you see a coin's promotional materials for an ICO and want to archive that as they change their specs on the fly, leading up to their mainnet release. How would someone go about this? Denarius has a great feature built into the wallet called Proof of Data which will hash the file. Along with this a user can upload that file directly to IPFS for archiving purposes. The POD then would act as showing that uploaded file is the same unchanged file. Lets begin with an example of how to do this.

It's been a while since I have seen a countdown timer on a mainnet release, so I was curious what they are offering. Reading both PDF's being offered shows something isn't right. What are the odds they change this after they got everyones' money upfront before the timer counts down to release? Who knows, so lets archive now and find out later.

First I download the Lite Paper. Then I go to the proof of data tab in the QT wallet, Select File, enter narration and then click Create Timestamp.

On success we get a Denarius address as the POD file hash.

Then go over to the Jupiter Tab and select the same file. I want to POD the IPFS upload as that timestamps when I archived this into IPFS itself.

After paying a small fee we get all the rest of the information.

Can then click on View Upload file on Infura to get the Link, pretty neat.

I will leave it up to the user why I am showing this and comparing to 2 pieces of ICO material together showing different coins.
