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

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

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.

You can add the new version of electrum to T.a.i.l.s

Create an admin password and unlock your persistence storage, then start tails.
Once tails is open, configure your persistence staorage and make sure personal data and addition software and bitcoin client is turned on. If it wasnt, configure and restart tails with admin password and persistence storage unlocked.
Now open the tor browser and proceed to electrum.org. Under the download selection, download the linux appimage and save it to the tor browser folder right above persistence on the lower left side of screen.
Once downloaded and saved to tor browser folder, drag and copy the image to the persistence folder.
Once in the persistence folder, right click on the appimage and go to properties. Then click on permissions tab and check Allow executing file as program and exit the properties box.
Now double click on the image in persistence and everything should be working.
Have used this on TAILS 3.13 ENJOY

RaspiBlitz - use blockchain from Windows machine

I could use some help configuring RaspiBlitz. I have a bitcoin node running on my windows machine with the blockchain fully synced. I would like to use blockchain on my spare hard drive for my RaspiBlitz node, but my linux experience is lacking.
Any advice on how to mount the spare hard drive in RaspiBlitz and transfer the blockchain from windows (I keep getting permission errors)? Once I get past that, any configuration tips on how to point bitcoind to the transferred folders/file?
Thanks!

Malware and potential Bitcoin miner + Misc issues

I recently acquired very blatant Malware downloading something. I've ran Malwarebytes, rkill, Adwcleaner, and Hitmanpro and they cleaned everything up and now Malwarebytes comes up with nothing. I attempted to use Roguekiller but the exe refuses to run. So I'm not sure I'm good on this front. (I haven't attempted combofix.)
More importantly, I believe I have a bitcoin miner of sorts that wasn't dealt with by them. Whenever I am connected to the internet my CPU and Memory usage skyrockets. It's doing so via sprlzhc.exe. Which is doing so via tiauhrz.exe, via wdemtpisvc.exe. Google searching all of them comes up with nothing so I'm assuming it is custom malware. Totalvirus via Process Explorer also doesn't work because of the path.
Pictures here (Offline - Online): https://imgur.com/a/ZMsmx
Note the two CLIENTS in my applications. They are only there online. The sprlzhc.exe will open multiple and start a new one and close an old one frequently which I think is proof of mining. (I assume it works similar to folding @ home.) Also the Ctfmon.exe wasn't there earlier. Only just showed up now when I took the picture.

Tiauhrz is located at useAppdata/Local/tiauhrz and I'm unable to delete it or even enter it. I need permission for it. A thread I found suggested to boot with a linux usb drive to bypass the NFTS permission, which I'm about to attempt.
The wdemtpisvc.exe however is located in /System32 so I'm hesitant to delete it. It's properties says it was created during the infection, though. Hovering over says "Company: Toshiba" so I'm even more suspicious considering I built the PC.
I tried safe mode and System restore (Wouldn't open) so now I'm going to attempt the linux method and delete the tiauhrz folder, but I want to know if deleting wdemtpisvc is safe or not. Will this method work? Is there anything else I should attempt as well? Should I just wipe the drive?
Sidenotes: It greyed out some of my shortcuts. Also, Whenever I search something with chrome it does a google search, then redirects to search60-com with the search. I have yet to see how it screwed up Firefox. Any ideas on these?

A simple guide to financial sovereignty (set up your Bitcoin fullnode)

In 2009, a 9 pages white paper by satoshi Nakamoto described a protocol that made central banking obselete. It's a new paradigm where monney is no longer controlled by a few, but by the whole network.
The shift is already happening, as we speak, even if it's hard to see, especially if you lack the fundamental knowledege of cryptoghraphy, game theory and economics. It's just a matter of time before you realize that Bitcoin is hard money, and for the first time we have a framework to apply austrian economics, without permission. Time to reset the keynesian monopoly game.
I don't think people are inherently bad, it's just that in the actual system (which I call the legacy system) people are incentivised to make decisions that are good from their individual perspective, but unfortunately, the sum of those individual decisions are bad from the collective group perspective. That's just plain simple game theory. What makes Bitcoin so special is it's perfectly aligned set of incentives that makes individuals and collectives outcomes better. It switches the economic model from keynesian to austrian, inflation to deflation, spending to saving, modern slavery (throught debt) to financial sovereingty, de-evolution to evolution. We are currently shifting from fiat to Bitcoin.
What you think capitalism is has nothing to do with what Capitalism really is in a free market. Capitalism is beautiful, it's simply the act of evolution, saving and optimising for consumming only what's needed (don't forget with live in a world with limited ressources, yes we all forgot). Stop spending and start capitalising, that's what we should be doing. But it's near impossible in a world run by socialists imposing debt using violence. What do you think back the US dollar ? gold ? no no, only tanks, aircraft carriers, soldiers and corrupt politicians.
Our only way out of this madness with the minimum violence is Bitcoin.
To be clear, if you dont run a fullnode, then you don't validate the transactions yourself (which is one purpose of running a fullnode). If you don't do the job yourself, then you have no other choice then to trust someone else for it. That's not necesserely a bad thing, as long as you are aware of it. You have no say in what defines Bitcoin, you enforce no rules. You serve no purpose in the Bitcoin realm. Why not !
Now if you seek financial sovereignty and want to take part in the new money paradigm, you will need to operate a fullnode and get your hands a little dirty. This guide hopefuly will take you there while walking you through the steps of setting up your autonomous Bitcoin Core full node.
Why Bitcoin Core ? simply because the Bitcoin core client implement and enforce the set of rules that I myself define as being Bitcoin.

Prerequis

install

Choose & download the latest binaries for your platform directly from github: https://bitcoincore.org/bin/bitcoin-core-0.16.2
at the time of writing, the latest bitcoin core version is 0.16.2
wget https://bitcoincore.org/bin/bitcoin-core-0.16.2/bitcoin-0.16.2-x86_64-linux-gnu.tar.gz tar -zxvf bitcoin-0.16.2-x86_64-linux-gnu.tar.gz sudo mv bitcoin-0.16.2/bin/* /uslocal/bin/ rm -rf bitcoin-0.16.2-x86_64-linux-gnu.tar.gz bitcoin-0.16.2 # clean 

firewall

Make sure the needed ports (8333, 8332) are open on your server. If you don't know, you can & should use a firewall on your server. I use ufw, which stands for uncomplicated firewall.
sudo apt install ufw # install ufw 
configure default rules & enable firewall
sudo ufw default deny incoming sudo ufw default allow outgoing sudo ufw allow ssh # if you operate your server via ssh dont forget to allow ssh before enabling sudo ufw enable 
Once your firewall is ready, open the bitcoin ports :
sudo ufw allow 8333 # mainnet sudo ufw allow 8332 # mainnet rpc/http sudo ufw allow 7000 # netcat transfert (for trusted sync) 
check your firewall rules with sudo ufw status numbered

init

Start bitcoind so that it create the initial ~/.bitcoin folder structure.
bitcoind& # launch daemon (the & run the copmmand in the background) bitcoin-cli stop # stop the daemon once folder structure is created 

config

In my case, for a personnal fullnode, I want to run a full txindexed chain. We only live once and i want all options to be possible/available :) If you plan to interact with the lightning network in the future and want to stay 100% trustless, I encourage you txindexing the chain (because you'll need an indexed chain). it's not hard to txindex the chain later on, but the less you touch the data, the better. so always better to start with txindex=1 if you want to go for the long run. It only adds 26Go on top of the 200Go non indexed chain. So it's worth it !
Just to get an idea of the size of the bitcoin core chain (August 23, 2018) :
network folder txindexed height size
mainnet blocks + chainstate yes 538.094 209Go + 2.7Go = 221.7
mainnet blocks + chainstate no 538.094 193Go + 2.7Go = 195.7Go
testnet blocks + chainstate yes - -
testnet blocks + chainstate no 1.407.580 20Go + 982Mo = 21Go
Create a bitcoin.conf config file in the ~/.bitcoin folder. This is my default settings, feel free to adjust to your need. [ see full config Running Bitcoin - Bitcoin Wiki ]
# see full config here https://en.bitcoin.it/wiki/Running_Bitcoin # Global daemon=1 txindex=1 rpcallowip=0.0.0.0/0 # bind network interface to local only for now server=1 rest=1 # RPC rpcport=8332 rpcuser=admin rpcpassword=password # define a password rpcworkqueue=100 # zmq zmqpubrawblock=tcp://*:8331 zmqpubrawtx=tcp://*:8331 #zmqpubhashblock=tcp://*:8331 #zmqpubhashtx=tcp://*:8331 # numbers of peers. default to 125 maxconnections=10 # utxo cache. default to 300M dbcache=100 # Spam protection limitfreerelay=10 minrelaytxfee=0.0001 

Sync the blockchain

There are 2 ways you can donwload/sync the bitcoin blochain :

Network sync (default)

If this is the first time you are setting up a bitcoin full node, it's the only way to trust the data. It will take time, depending on your hardware and network speed, it could vary from hours to days. You have nothing to do but leave the bitcoind daemon running. check status with bitcoin-cli getblockchaininfo, kill daemon with bitcoin-cli stop.
Remember that this is the only procedure you should use in order to sync the blockchain for the first time, as you don't want to trust anyone with that data except the network itself.

Trusted sync

Skip this chapter if this is the first you're setting up a full node.
Once you operate a fully "network trusted" node, if you'd like to operate other nodes, syncing them from your trusted node(s) will go much faster, since you simply have to copy the trusted data from server to server directly, instead of going throught the bitcoin core network sync.
You will need to transfer the chainstate & blocks directory from the ~/.bitcoin folder of one of your trusted node to the new one. The way you achieve that transfer is up to you.
At the time of writing (August 23, 2018), the txindexed blockchain (chainstate + blocks up to height 538.094) is around 220Go. Moving that quantity of data over the network is not a trivial task, but if the transfer happens between 2 reliable servers, then netcat will be great for the job. (netcat sends raw tcp packets, there is no authentification or resume feature).
Note: with netcat, if one of the servers connection is not stable, and you lose connection, you will have to start again. that's a bummer. in that case you are better of with tools like rsync or rcp that let you resume a transfer.
In order to make the transfer a simple task, make sure you do the following on both of the receiver and the sender server :
Once both your servers (receiver & sender) are netcat ready, proceed as follow :
This is the transfer times for my last data sync between 2 servers hosted at time4vps.eu (not too bad) | folder | size | transfer time | - | - | - | blocks | 209Go | 5h20 | chainstate | 2.7Go | 4min

bitcoind as a service

For ease of use and 100% uptime, simply add bitcoind to your system service manager (in my case systemd) create the file /etc/systemd/system/bitcoind.service and add the following to it :
[Unit] Description=Bitcoin daemon After=network.target [Service] User=larafale RuntimeDirectory=bitcoind Type=forking ExecStart=/uslocal/bin/bitcoind -conf=/home/larafale/.bitcoin/bitcoin.conf ExecStop=/uslocal/bin/bitcoin-cli stop KillMode=process Restart=always RestartSec=120 TimeoutSec=240 # Hardening measures #################### # Provide a private /tmp and /vatmp. PrivateTmp=true # Mount /usr, /boot/ and /etc read-only for the process. ProtectSystem=full # Disallow the process and all of its children to gain # new privileges through execve(). NoNewPrivileges=true # Use a new /dev namespace only populated with API pseudo devices # such as /dev/null, /dev/zero and /dev/random. PrivateDevices=true # Deny the creation of writable and executable memory mappings. MemoryDenyWriteExecute=true [Install] WantedBy=multi-user.target 
Don't forget to correct the user name & the bitcoin.conf path. Once the systemd bitcoind config file is created, reload system services and start the bitcoind service:
sudo systemctl daemon-reload # reload new services sudo systemctl enable bitcoind # enable bitcoind sudo systemctl start bitcoind # start bitcoind sudo systemctl status bitcoind # check bitcoind status 
If everything worked, status should output the following:
● bitcoind.service - Bitcoin daemon Loaded: loaded (/etc/systemd/system/bitcoind.service; enabled; vendor preset: enabled) Active: active (running) since jeu. 2018-08-23 21:17:41 CEST; 5s ago Process: 5218 ExecStart=/uslocal/bin/bitcoind -conf=/home/larafale/.bitcoin/bitcoin.conf (code=exited, status=0/SUCCESS) Main PID: 5219 (bitcoind) CGroup: /system.slice/bitcoind.service └─5219 /uslocal/bin/bitcoind -conf=/home/larafale/.bitcoin/bitcoin.conf 
The bitcoind service is active and will automatically restart on statup/crash. Wait a couple minutes until the bitcoin-cli getblockchaininfo command returns the chain status. You can also query the rest interface by opening http://nodeIP:8332/rest/chaininfo.json in your browser.

Conclusion

You now have a full Bitcoin core node running on it's own. What's next ? Well I never blogged before, this is the first time I am outsourcing some of my work. I'm a passionnate enginner working on all kind of technologies. I've been dedicating half of my time to Bitcoin for the last 2 years already, so if this guide was usefull and want to go deeper , just let me know, depending on the feedback I get, i'll consider outsourcing more interesting work. For example next post could be about setting up an Electrum Server so you can safely use SPV wallets trusting your own fullnode.
Also I'm currently working on a trustless bitcoin payment processor called 8333, make sure you follow @_8333_ on twitter. I think I will release the project end of 2018. Ping me if interested.
