00:10     Welcome back. In this video we will be looking at the changes we made to our QT. Now that we have compiled we are ready to launch our Vision X QT.



The first thing to do is to remove the make install command.  Then we will navigate to our QT folder as before. "cd src", "cd qt" then we need to launch our wallet as before, "./visionX-qt".



00:43     As you can see we have changed the splash image. I actually changed the dimensions from its previous size as the old one was a bit messy and squashed. You can now see our logo and coin name clearly allowing enough space for the text at the bottom.



01:05     With the QT now open, we can see that we have successfully changed the images . The horizontal image has been replaced. Also, you can see we have replaced the small one here and the icon on the side has been replaced. Looking at the "about" tab we can see our logo more clearly now.  We have kept the original Reden background for this QT.



01:32     If you wanted to change the background, you just need to change the PNG in the images folder called "walletframe".  Remember, if you choose a darker background you will need to change the text color in the CSS file.  Otherwise you will not be able to see any text, especially in the "recent transaction list".



01:55     There are a lot of changes that can be made to a QT visually.  You can make it look unique to your coin.  Maybe change the layout in the CSS file or use the images to show off your brand. Changing the icons is also a good way to put your mark on it.  There are many icons in the icon folder that can be replaced.  Just remember the rule.  Change out the image for the same size and format.  Another thing to know is whenever you replace images you need to "make clean" and compile.  Compiling without making clean,  will not show any changes.



02:36     As you now know, when we make clean, the compile takes a long time.  So you should try to make all your changes in one go before you compile again.  When you make changes to the CSS file for things like font colors and borders, you can compile without having to make clean.



03:00     Let's exit our QT now and navigate back to our master folder.  We need to take a look at what data is stored from our wallet.  Click on the Home tab.



03:18     Now we are going to open our hidden files.  To do this, on your keyboard hold control and press H. We can now see all of our hidden files. Most have been created when we installed our dependencies.  The one we are interested in is  ".visionXcore".



03:39     In this hidden folder we can see other subfolders.  These are storing information for our QT. Information such as backups,  blocks,  chainstate and the database.  You can also see the debug log.  This will show you how your wallet is behaving. You can check this file for errors if you ever have problems with your QT.  Here you can see information about peers.



04:12     This file named "wallet.dat" is the most important file in this folder.  It stores all your private key information.  If you lose this,  you will lose all the coins in this wallet. Scammers or hackers are solely targeting this file.  So it is best to always copy and paste it onto a flash drive. To move your wallet from your current PC.  All you would have to do is download the wallet on your new computer, run the wallet.  Navigate to the hidden files and replace the "wallet.dat" file with yours.  You will instantly have your funds in your new wallet.



04:55     If you don't have a backup for this file there is no way to retrieve your coins, if your computer crashes or you blow a hard-drive.  This has happened to me many times.  Do not make that mistake!



05:08     It is also important to save the "wallet.dat" file as soon as you have mined your pre-mine.  We will talk about this more later.



05:18     Next we have our Vision X configuration file. The first thing you notice is the line that states only ipv4 connections.  Ipv4 is faster than IPv6,  so that is used.  We need to make sure the seeds provide the fastest connections.  With this the QT, you can see that we have a list of seed nodes hard-coded into this file.  This is the IP address, and this is the Reden port number.  This means this wallet will automatically connect to these other wallets.



06:05     The purpose of this is to allow new wallets to sync with the blockchain faster.  However, as you can see these are Reden's.  As we are now going to create our own blockchain we need to remove the hard-coding.  We do not want these seed nodes in our config file for our chain.  In fact,  we should not need any addnodes in this folder if we do it right. Our main seed node should provide all the support needed to allow a fast sync.



06:38     In our next video, we will be editing the source code.  I will first show you how to remove this hard-coding as well as removing other things in preparation for our own blockchain.
