  1. Grab the latest QT wallet with IPFS built in and have 0.1 D or at least something small to pay the PoD fee. IPFS is free and can skip the PoD portion of this if you just want to upload files. Lets pick a good file to Proof of Data against and then upload into IPFS. Current Release: https://github.com/carsenk/denarius/releases/tag/v3.3.9.6 QT Wallet: https://github.com/carsenk/denarius/releases/download/v3.3.9.6/Denarius-v3.3.9.6-Win64.zip Download a file, I am going to use the denarius logo from denarius.io and lets proof of data this and upload to IPFS as a great example of how powerful this is. Here's a link but just right click the image on the homepage and save to your hard drive. https://i2.wp.com/denarius.io/wp-content/uploads/2017/11/denarius-256.png?w=256&ssl=1 Go to the Jupiter Tab Select your file, in this case select the image file we just downloaded. Click Upload to IPFS (The Wallet will freeze while the upload is taking place) After the upload you will get an IPFS Hash along with being able to click the link to see the file in your web browser. Success, and currently there are file limits on uploading through the wallet. I was not able to upload the QT.zip yet. Lets Proof of Data this file for good measure, so the original hash is located on the Denarius blockchain. Go to Proof of Data tab in QT Wallet Select our image, then put a simple narration in and then click Create Timestamp This now gives us a D address where the hash matches the image. Now if we download the image we uploaded to IPFS we can verify the file against the blockchain by checking against PoD again. Here is our set in the blockchain address based on the image file or can Click Check Transaction to get to your PoD transaction. https://www.coinexplorer.net/D/address/DQQxYgD1KPzmoQGeL1JyXZk2JhZPfiaXsY
  2. First you need the QT Wallet started and some Denarius coins. Proof of Data costs 0.001 D as of the writing of this guide. Proof of Data can give a hash against a file like an MD5 checksum. Except this checksum is a hash stored on the blockchain with a time and date, proving your data hasn't been altered. Lets start with an easy to find image. Carsen's github with the Denarius image located here. https://github.com/carsenk/denarius I am going to right click the Denarius logo and save to my hard drive as the example. Now open the QT Wallet to the Proof of Data tab. We want to select file, choose the image we just saved which is a long string of numbers.png. After selecting the file type in up to 24 Characters. I am going to use Denarius Logo. And then click Create Timestamp. Now we get the success message and also a Generated Timestamp Denarius Address. A transaction hash is generated after clicking OK. Input the generated address into the block explorer to see what we just did. https://www.coinexplorer.net/D/address/D9hq7DB78uh8SGmoiA3iCaqGcW3RcvmawA Now what can we do next? Lets put the same image in and Create Timestamp again. We get the same address again. https://www.coinexplorer.net/D/address/D9hq7DB78uh8SGmoiA3iCaqGcW3RcvmawA Thats the basics, and this works for more than just image files. I personally use PDF's and link the Denarius block explorer with PDF in emails so no one is changing files on me.
