(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:

If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

Let me love the Bitcoin, please.

After reading tiny snippets about Bitcoin all the time I decided to take a closer look at it ... and I was floored.
Please don't get me wrong, I really really really want to love the concept, but it seems to be more or less unusable. There are some huge upsides to it: Built on mistrust, fixed amount of money, decentralized system, anonymity and so on. But my reality looked something like this:
Now as you might say, I should have read up on the details (blockchain!) before - but getting started seems to be a big hurdle for the non-geeks out there. Nothing like "get started in seconds!". Even I had some trouble grasping the concept, and I'm sitting in front of a computer for about two decades now.
But wait, there's more! Since my connection is still under heavy load from the client, I could read up on all the things I have missed, and I found some inherent flaws:
For me, Bitcoins could be an awesome form of worldwide, internet-based form of micropayments. The biggest market would be developing countries. But there are technical and legal barriers which push it into a corner for geeks who see conspiracies everywhere and want to crash the system ... which is exactly not what it should be. I read about Ripple, it seems to be a better alternative just because of the possibility for easy money exchanges - and it includes Bitcoin, too.
So, is there something I just don't get yet? I get the impression Bitcoin is a great idea, but just the prototype for something better.

Reddcoin Core 2.1

Reddcoin Core 2.1 will be an update to the core components of Reddcoin : reddcoin-qt and reddcoind. One of the key improvements is expected to be a speedup for the blockchain synchronization process - something we read a lot of negative comments about - and understandably so. I have a 2011 vintage laptop which I use for testing. It takes more than a few days to chew through the blockchain sync. Old though it may be, it’s my favorite benchmark of acceptable performance.
First let me explain why blockchain sync is slow, then explain what will be done to speed it up.
The Reddcoin blockchain is up to block 1760528 whereas Bitcoin is up to block 472265 (as I write this). That the Reddcoin blockchain is 3.7 times longer despite only having been alive since 21 Jan 2014 versus Bitcoin’s birth in 2009 may come as a surprise, until you remember that Reddcoin’s block time of 60s is one tenth’s of Bitcoin’s 10min block time. Under normal operating conditions on recent hardware you are unlikely to notice any performance hit. But the blockchain synchronization process cruelly throws the spotlight on one of the more CPU intensive aspects of maintaining a blockchain - block validation - something every network node does whether a new block is propagating through the network or an old block is being synced from either a bootstrap file or a network peer. Whatever performance issues Bitcoin 0.9 had during blockchain synchronization, Reddcoin necessarily suffers 10x worse.
Whilst making Bitcoin comparisons, it’s useful to recall the origins of our current Reddcoin Core 2.0.
Reddcoin Core 2.0 is based on Bitcoin 0.9 with the PoSV code from Reddcoin 1.4 reintegrated - work that @Gnasher completed almost a year ago specifically to incorporate the OP_RETURN feature from Bitcoin 0.9 which is a key enabler for Redd-ID. Peering at the Github tea leaves it is evident that synchronization performance was thought to be an issue in Bitcoin 0.9 because there were features introduced in later versions to address specifically this concern. And it is precisely these features we plan to integrate into Reddcoin Core 2.1 as part of the overall strategy of shadowing the Bitcoin code base as and when the need arises to move things forwards. My personal dream is getting SegWit live on Reddcoin, but clearly with rather empty blocks and 10x the capacity of Bitcoin, we’re way off needing something like a Reddcoin Lightening Network yet. But it is good to know we have that option open to us in our future road map.
Therefore the work currently underway for Reddcoin 2.1 is expected to include two features that will accelerate the blockchain synchronization process:
1 - “headers first” synchronization taken from Bitcoin 0.10
2 - Removal of the openssl lib dependency and replacing that very generic and slow elliptic curve crypto code with an optimized internal implementation originally developed for Bitcoin 0.12.
Whether this work will get Reddcoin Core all the way up to Bitcoin 0.12 remains to be seen. The base target is Bitcoin 0.10 with at least one 0.12 feature.
I don’t yet know what kind of speedup we should expect from this, but I am hopeful of something significant. I plan to publish timing comparisons once I have a beta of 2.1 with these features working. Anyone eager to know sooner is welcome to test Bitcoin 0.9 vs. Bitcoin 0.12.
Meanwhile with Redd-ID close to entering beta testing and a great mobile wallet team taking shape off the back of the recent upsurge of interest in Reddcoin, we can expect 2017 to be a good year for Reddcoin.
Keep on staking !

Ahhh one of the worst things about Bitcoin.... I have dealt personally with this issue. The first time I ran Bitcoin Core (to use with Bitcoin Armory), I let my computer run for a full day before it finally completed it. This was over a year ago. ... Always use the latest release version of Bitcoin Core (includes bitcoin-qt and bitcoind) downloaded from the official site at www.bitcoin.org. An upgrade is safe and easy, just safely exit Bitcoin Core first and make a new secure backup of your wallet.dat before you upgrade. bitcoin-qt segfault on corrupt wallet #3333. Mavericks crash on blockchain download. #3317 [qt] ... Bitcoin-qt on Ubuntu 64 takes 16777216 TB virtual memory, slows system #2485. ... Please help Synchronizing with Network stuck at 99.7% #1682. The reason why users choose core wallet is to run a full node, support the network and additionally have full control over their funds as it offers better privacy and security. On the other hand why users won’t choose QT wallet is mainly because of wallet synchronization issues. Before we can use this wallet we need to wait for it to completely synchronize with the network. Head over to bitcoin.org and download the bitcoin core wallet. When you first get the client up and running, you will notice a box at the bottom called “synchronizing with the network”. As bitcoin core is a full node, get ready for a long wait, as you begin to download close to 8 years worth of blockchain records!
