How to run Bitcoin Core 0.20.0 on Ubuntu Server 20.04 LTS using a Raspberry Pi 4 (or Virtual Machine)

I was helping someone on twitter with this so I figured I'd share the information here as well so that other people would have an easier time than I did.
I'm going to explain how to do this setup on a Raspberry Pi, but note that this should work on a VM as well. You can also set up and run the node headless this way, but I will be explaining how to set up the node using a monitor that you can then later disconnect and access remotely once everything is setup.
Hardware:
-Raspberry Pi 4 (2GB RAM minimum) preferably 4GB RAM -Raspberry Pi 4 Heatsinks -Raspberry Pi 4 case -Micro HDMI cable -USB-C power cable and wall adapter -Monitor -Keyboard and mouse -Ethernet cable (Optional) -16GB or larger microSD card -500GB or larger external hard drive (SSD or portable)
Node Requirements: -50 KBps upload internet speeds (Most people should have this) -Unlimited or high data cap internet download/upload service -6 hours or longer per day dedicated run time
Okay, once you have the hardware its time to get started!
The first thing you'll need to do is install the Raspberry Pi imager, this is how we're going to install Ubuntu onto our Raspberry Pi. After your download and install finishes, open the imager.
  1. Click the "choose OS" box and from the list select Ubuntu, then select Ubuntu Server 20.04 LTS (Raspberry Pi 2/3/4).
  2. Insert your microSD card to your computer directly or via a USB converter. Click "choose SD card" and select your inserted microSD card.
  3. Click "Write" and wait for the imager to finish flashing the OS onto your card
When it is done, remove the SD card and reinsert it to access the files installed. You can choose the overclock the Raspberry Pi by editing the config file. To connect to the Raspberry Pi remotely, you'll need to create an SSH file. If you're on windows this is pretty easy. In the File Explorer, highlight the address bar at the top, erase the text and type cmd, press enter and the Command Prompt will pop up. Type the following:
echo\ssh
This will create an SSH file in your SD directory so that you can remote access the Rasberry Pi later. Now you can go ahead and eject the SD card from your computer.
Now we can set up the Raspberry Pi
Go ahead and connect all your peripherals to your Raspberry Pi, insert the microSD, and connect it to power to turn it on. Give it a moment to boot up, then when prompted enter "ubuntu" for the password. It will make you change the password. Afterward, it will print a bunch of information to the screen, write down the IPv4 address, this is the IP address you'll use to remote access the Raspberry Pi. Now, at any time you can remote access your Raspberry Pi by entering a terminal on another PC in your network and typing:
ssh [email protected](your IP address)
The next step is to install a desktop. There are plenty to choose from so feel free to use a different one than what I use, you can also choose to ignore this and to just work from in the terminal from this point forward.
You need to update all the repositories so type: (Note you'll either have to be connected by ethernet or have edited the network-config file to setup your wifi in advance)
sudo apt-get update
Once it's done updating type the following to upgrade your system:
sudo apt-get upgrade
Now that you're up-to-date, you can install the desktop using the command:
sudo apt-get install ubuntu-gnome-desktop
This will take a while to download and install so just sit back and let it do its thing. Once it's done downloading, restart your Raspberry Pi and log in with the password you changed earlier. Your first boot may take a while so just be patient, don't freak out if you see a single purple square in the center of the screen while it's loading. You should now have the Ubuntu desktop ready to go and now it's on to installing Bitcoin Core!
Installing Bitcoin Core 0.20.0
Since we're running Ubuntu Server 20.04 LTS, it should come preinstalled with the Snap Store. This makes installing apps very easy and works similar to pip install in Python. Simply open your terminal and type:
sudo snap install bitcoin-core
This will install Bitcoin Core into your Snap folder and will add the application to your system. Unfortunately, there are still a few steps left before we can begin downloading the blockchain. By default, Bitcoin Core doesn't have the removable-media Plug connected to the Socket. You can view this by typing:
snap connections bitcoin-core
This means when you try installing everything onto your external hard drive, Bitcoin Core won't be able to identify it or write to it even when passed the directory path. To fix this first locate your Snap folder, make a copy of the bitcoin-core folder inside, and paste it into your external drive.
NOTE: You must make a copy, you can't just move the snap file to the external drive.
Now, you can connect the removable-media Plug to the Socket by typing:
sudo snap connect bitcoin-core:removable-media :removable-media
This gives you the read/write permissions necessary to access the /media path. Finally, you can now launch Bitcoin Core and select "use a custom directory path" when prompted. Highlight the current directory path and replace it with the path to your external hard drive, it should look something like this:
/media/(external drive)/bitcoin-core/common/.bitcoin
This is why we had to make a copy of the bitcoin-core folder to the external drive earlier, the Bitcoin Core application will create the new data directory through ".bitcoin". Hit "Okay" and the application will begin synchronizing with the network! Once the synchronization is finished your very own node will be up and running!
EDIT: (08/01/2020) Bitcoin Core 0.20.01 has been released, I will update the tutorial soon with how to run the latest release.

Putting together a scripting language hackathon - need advice

I'm putting together a webinar based hackathon for a local Linux user group to learn Bitcoin Scripting Language. First question: there are a number of tutorials on BitcoinScripting Language and I know Bitcoin Cash and SV are forks and,so, the same or am I assuming too much? I know they made changes to the forks but would any of them affect beginners? Or, similarly, are there any similar tutorials for the forks?
Second, I'm assuming the first step for students would be to install a server on their own PCs. It's been years since I have had one and am having a hard time getting one set up. I'm on Ubuntu. I could try to build from source if there was a detailed step-by-step but prefer something easier (not all the Linux group would be able to build from source and the focus is on the scripting language). So could someone walk me through setting up a server?

How to get a public static ip for your local lightning node

My lightning node is a node that is running locally on my server hardware in my house down under, far from the New Jersey Digitalocean datacenter, which is what will come up if you look up the ip of the node. This is done via an OpenVPN tunnel from your local machine to a VPS. I am doing this by renting a VPS from Digitalocean for $20 a month (2 vCPUs, 2GB RAM) running Ubuntu 18.04. You can do this just as easily on a $5 a month VPS with 1 vCPU and 1GB RAM or even a $2.50 a month VPS from Vultr with 512MB RAM. I needed the extra power because I have many web services running there as well.
This setup allows me to have a highly available lightning node, not affected by my home IP address changing. If you are using a mobile connection or have a CGNAT, you wont be able to port forward for your lightning node. This setup allows you to do so. You can also use this to make a portable lightning node, which can get you a full lightning node wherever you have power and internet, without having to mess with network settings. If you don't want others to know your home IP, this is a good option for privacy.
  1. Setup a local lightning node, preferably on a linux machine. I followed the Raspibolt tu`ial (with some tweaks) on a 2 vCPU and 8GB RAM VM running Ubuntu 16.04.
  2. Get a VPS with a static IP address. Digitalocean and Vultr VPSs already are. This VPS wont need much power, so get the cheapest one you can.
  3. Secure the VPS. I used this tutorial. Essentially, setup a non root user, use ssh keys, and setup ufw. Also make sure to allow port 9735 through ufw for lightning. I also additionally made adjustments to the ssh config and installed fail2ban.
  4. Setup an OpenVPN server on the VPS. I used this tutorial.
  5. Install on OpenVPN client on the local linux machine and connect to the server. The tutorial from step 4 shows how to this. Keep this connected for step 6.
  6. SSH into the VPS and figure out the OpenVPN IP address of the client. It should be 10.8.0.x. To figure out the x, setup a simple python web server or something on the local machine on port 8000 or something and open the port on ufw in the local machine. Keep the OpenVPN connection, and use a new ssh session when accessing your local machine. Don't kill the OpenVPN connection, as it may complicate things when finding the ip.
    mkdir testweb
    cd testweb
    echo hello >> index.html
    sudo ufw allow 8000
    python -m SimpleHTTPServer 8000
  7. SSH back into the VPS. Run the curl command below, and try all the numbers between 2-10 for x. When you get hello as your output, then you found the right IP. I found mine at 6. You may have to try higher numbers, but this is unlikely. You can kill your python webserver on your local machine once you find it.
    curl 10.8.0.x:8000
  8. Once you have the IP, you want to make this static, so it doesn't change when you reconnect. This is done on the VPS side, so ssh back into the VPS. This tutorial worked for me. Just make sure to change values like the CommonName and and the IP to match yours (client1 and 10.8.0.x). If it doesn't work search "make openvpn ip static" and look around.
  9. SSH into your local machine, and make the OpenVPN connection persistent. You can kill the OpenVPN connection now. Doing this and this worked for me. If it doesn't work search "openvpn keepalive" or "openvpn auto connect linux" or "make openvpn connection persistent linux".
  10. Restart your local machine, and make sure it connects on boot. Do the python webserver test again, and make sure the same ip is shown on the VPS, and it is still accessible.
  11. SSH back into the VPS. Now, you have to port forward with iptables. you have to add the 2 lines below starting with -A PREROUTING in the same place in your /etc/ufw/before.rules file. Here is what mine looks like. Change the x to your OpenVPN IP. Do sudo ufw disable and sudo ufw enable to restart ufw to update your changes.
    *nat
    :POSTROUTING ACCEPT [0:0]
    -A PREROUTING -i eth0 -p tcp -m tcp --dport 9735 -j DNAT --to-destination 10.8.0.x:9735
    -A PREROUTING -i eth0 -p udp -m udp --dport 9735 -j DNAT --to-destination 10.8.0.x:9735
    -A POSTROUTING -s 10.8.0.0/8 -o eth0 -j MASQUERADE
    COMMIT
  12. SSH into your local machine. Change your lnd.conf to match with this setup, like changing the externalip. Here is what my config looks like, a slight tweak from the Raspibolt one:
    [Application Options]
    debuglevel=info
    maxpendingchannels=5
    alias=GCUBED [LND]
    color=#68F442
    listen=0.0.0.0:9735
    externalip=157.230.95.74:9735
    [Bitcoin]
    bitcoin.active=1
    bitcoin.mainnet=1
    bitcoin.node=bitcoind
    [autopilot]
    autopilot.active=1
    autopilot.maxchannels=5
    autopilot.allocation=0.6
  13. Do a sudo service lnd restart to restart lnd and apply the changes. Remember to do a lncli unlock after any restarts. Your lnd node should now have a public static ip. Look it up a few hours after you do this on 1ml, your ip should be the one of your VPS now.
I am monitoring this for free with uptimerobot. It will notify you if it has gone down. So far mine has been running for 3 days and hasn't gone down.
EDIT: Formatting
EDIT 2: The main reason I didn't use a ddns or a hidden service was mainly for high uptime, and low latency. I am planning on developing a lapp with this node and I didn't want to risk any downtime. Running lightning as a hidden service is a great idea as well, this tutorial shows how to achieve something similar with the clearnet.
EDIT 3: You can achieve a similar result from using TOR

(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.

Dogecoin on Linux - The Complete Beginner's Guide

I'm writing this because I couldn't find a single condensed guide on compiling the wallet and running mining software on linux, specficially Ubuntu/Linux Mint. I combed Bitcoin and Litecoin forums for similar problems I was running into and eventually got everything nailed down, so here it is in one place, for new Shibes.
If you want to make a Dogecoin directory in your downloads folder to keep things organized, you will need to modify these commands to refelct the change. So instead of going to ~/Downloads/ you will need to go to ~/Downloads/Dogecoin and be sure to put the zipped files there when you download them, but the commands will be the same otherwise.
cwayne18 put in the work to make a PPA for the QT client here.
Ubunutu/Mint/Debian users should be able to install the client with the following commands:
sudo add-apt-repository ppa:cwayne18/doge sudo apt-get update && sudo apt-get install dogecoin-qt 
To update using this method, run
sudo apt-get update && sudo apt-get upgrade dogecoin-qt 
Compiling the Wallet Manually
I suggest using the PPA above, but if you want to compile manually, here you go.
1)Download the newest source from here. If you want to check out the Github page, click here
2)Unzip the package with the native client OR, navigate to your downloads and unzip
cd ~/Downloads unzip dogecoin-master.zip 
3)Now it's time to compile. You will need to install the dependencies, just copy and paste the following code. It will be a fairly large download and could take some time. It is always important to update before installing any new software, so we'll do that first and then install the dependencies.
sudo apt-get update sudo apt-get upgrade sudo apt-get install libssl-dev libdb-dev libdb++-dev libqrencode-dev qt4-qmake libqtgui4 libqt4-dev sudo apt-get install libminiupnpc-dev libminiupnpc8 libboost-all-dev build-essential git libboost1.53-all-dev 
4)Once that is done, go to the doge-coin master directory and compile:
cd ~/Downloads/dogecoin-maste sed -i 's/-mgw46-mt-sd-1_53//g' dogecoin-qt.pro qmake USE_UPNP=- USE_QRCODE=0 USE_IPV6=0 make -j3 
After running the qmake command you will likely see some text similar to
Project MESSAGE: Building without UPNP support Project MESSAGE: Building with UPNP supportRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized. 
It's perfectly normal, so don't worry about that.
Your Dogewallet is ready to go! The executable is in ~/Downloads/dogecoin-maste and called dogecoin-qt. Your wallet information is in ~/.dogecoin. You can run the wallet at any time by opening terminal and typing
cd ~/Downloads/dogecoin-maste ./dogecoin-qt 
Future upgrades to dogewallet are easy. Back up your wallet.dat, and simply follow the same directions above, but you'll be unzipping and building the newer version. You will likely need to rename the old dogecoin-master directory in ~/Downloads before unzipping the newest version and building. Also, it is likely that you will not need to install the dependencies again.
Alternate Method For Installing Dogecoin Wallet from Nicebreakfast
After installing the dependencies listed in step 3, open terminal, then navigate to where you want Dogecoin Wallet stored and run:
git clone https://github.com/dogecoin/dogecoin ./autogen.sh ./configure make 
then when the wallet is updated just run
git pull 
from the dogecoin directory.
GPU Mining
GPU mining requires CGminer. My suggestion is to get the executable already built. The creator of cgminer has removed the built file from his website, but I've uploaded it here
sudo apt-get install pkg-config opencl-dev libcurl4-openssl-dev autoconf libtool automake m4 ncurses-dev cd ~/Downloads tar -xvf cgminer-3.7.2-x86_64-built.tar.bz2 
Don't use anything newer than 3.7.2. The newer versions of CGMiner don't support GPU mining.
That's it! You have cgminer ready to go! You will run cgminer with the following syntax
cd ~/Downloads/cgminer-3.7.2-x86_64-built/ ./cgminer --scrypt -o stratum+tcp://SERVERNAME:PORT -u WORKER.ID -p PASS 
A good guide for fine tuning cgminer can be found here; follow the litecoin example.
EDIT
I had trouble getting cgminer running with a single line command, but running it via an executable .sh file works. This is covered in the cgminer setup guide I posted above but I'll put it here too. In the same directory that has the cgminer executable, you need to make a file called cgminer.sh and make it executable. It should contain the follwing:
export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export DISPLAY=:0 find *.bin -delete sleep 5 ./cgminer 
Then you can call cgminer in terminal by doing ./cgminer.sh You will need a cgminer.conf file containing all your options. All of this is covered in the guide that is linked above.
A quick note about AMD drivers: They used to be a huge PITA to install and get working, but the newest Catalyst drivers are great. There's a GUI installer, everything works out of the box, and there is a lot of documentation. You can download them here: AMD Catalyst 14.6 Beta Linux
CPU Mining
For CPU mining I use minerd because it doesn't require any work to get running, simply download it and get to work. Download the built file for your machine 32-bit or 64-bit, and then unzip it and you're ready to go!
cd ~/Downloads tar -xvf pooler-cpuminer-2.3.2-linux-x86.tar.gz 
The executable is called minerd and it will be in ~/Downloads but you can move it to wherever you like. To run it, pull up terminal and do
cd ~/Downloads minerd --url=stratum+tcp://SERVER:PORT --userpass=USERNAME.WORKERNAME:WORKERPASSWORD 
You're done! Happy mining!
Common Issues
I ran into this and I've seen others with this problem as well. Everything installs fine but there is a shared library file that isn't where it should be. In fact, it isn't there at all.
 libudev.so.1: cannot open shared object file: No such file or directory 
In terminal, do
sudo updatedb locate libudev.so.0.13.0 
And it will probably return a path /lib/x86_64-linux-gnu. Inside that directory there's a library file called libudev.so.0.13.0. You'll need to make a symlink (aka shortcut) that links libudev.so.1 to libudev.so.0.13.0 So, assuming you're working with libudev.so.0.13.0 do this
cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.0.13.0 libudev.so.1 
Now if you do
ln -l 
You should see
libudev.so.1 -> ./libudev.so.0.13.0 
Meaning you've made the symlink. Also, the text for libudev.so.1 will be blue.

Help in verifying my Ledger Nano S transactions with a Bitcoin Full node and Electrum server

From past suggestion I understand I can verify my hardware wallet transactions with the help of Electrum Server. I synced a full bitcoin node with txindex=1 but can not get Electrum app to connect to the local server.
I have followed this tutorial online: https://freedomnode.com/blog/69/how-to-install-an-electrum-server-using-full-bitcoin-node-and-electrumx
but the link to documentation for electrumx.conf does not work and can not find it.
Also tried installing Electrum Personal Server with no luck either.
Can someone direct me to a good tutorial for Ubuntu (Kubuntu)?

How to set up a Bitcoin full node on Linux VPS (pruning node)

This tutorial is for Linux Debian based OS (Ubuntu) at least with 1GB of RAM and 20 GB SSD. There are a few guides out there about how to set it up..but still not good enough. My Bitcoin Segwit node now is running on my VPS (yes I know it's not the best option but still..) I found few articles.. Due to these articles I’ve kept the below quite brief.
Please note: Before you start.. Your server may still be finishing installing and booting up during the first few minutes of activation. In this tutorial i'm using Linux Ubuntu 16.04 x64 LTS.
Secure VPS server (Firewall rules)
Command may disrupt existing SSH connection. Proceed with operation (y|n) ? Type y and hit ENTER.
Install the Bitcoin Core daemon (bitcoind)
Press ENTER to continue
Do you want to continue? Type y and hit enter.
Create a Bitcoin user
Enter new UNIX password (whatever you want) and then it will ask for your full name, room number, work phone, home phone, other (press the Enter key to skip). Is the information correct? Type y and hit ENTER.
Set up log rotation
Enter into it:
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Configure Bitcoin
Add to the file:
prune=550
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Press CTRL+D to log out of the Bitcoin
Configure swap space
The node we created only has 1GB so we’ll make some spare “virtual memory” using swap space.
Add this line at the end of the file:
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Set up the Bitcoin daemon to auto-run.
Enter into it (copy paste this):
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Reload systemd and start bitcoind:
You can use https://bitnodes.21.co/nodes/ to check if your node is running! If there is something wrong, please let me know that. I'm still learning ;)

How to set up an incentivized node in Ubuntu [likely works for other Linux as well…]

There has been a post lately about how you can participate in a program by bitnodes which is intended to incentivize running a full node.
In the comment section of the post there were some instruction by AndrewToth as to how to set the whole thing up. Unfortunately it didn’t work for me directly. I would therefore like to share how I finally managed to get it done.
If you would like to run a scrip to do all the heavy lifting for you, please perform steps 1, 2 and 12 now and then just copy paste this into the terminal and hit enter: wget -O bitnodes-incentive.sh http://pastebin.com/download.php?i=607WQaBy && sed -i 's/\/' bitnodes-incentive.sh && chmod +x bitnodes-incentive.sh && ./bitnodes-incentive.sh The script will also advise you to do the required port forwarding. You can look at the script here.
1 Find out your local IP by opening a terminal and typeifconfig. You will see your local IP listed under eth0 as inet addr. In the subsequent steps of this tutorial it will be referenced as $localip. So whenever you read $localip it means, your local IP you have just found out. It would be helpful to make this IP static.
2 Set up a full node. You need to download Bitcon Core, run it until you are synchronized. It needs to allow more than 8 connections and you therefore need to turn on port forwarding on your router. So if the machine which runs the full node has $localip in your subnet, you need to tell your router to forward port 8333 to $localip port 8333. If you open Bitcoin-QT it will tell you on the lower right corner, how many connections it has. If the number turns >8 after 5-10 minutes, you are all set. If you need a more detailed tutorial, you may try this one. Beware, if you don’t run a full node yet, allow it between 12 and 24 hours to synch.
3 Now you need to know your own public IP address. You can e.g. find it out like this. In the subsequent steps of this tutorial it will be referenced as $ip, so whenever you reed $ip it means, your public IP you have just found out.
4 Get a Bitcoin address. Please use one which you control the key to. I guess you know the deal. In the subsequent steps of this tutorial it will be referenced as $address, so whenever you reed $address it means, your Bitcoin address.
5 Open a new terminal and copy paste the following into the terminal each followed by enter key (beware $address means your address, no “$” sign needed): mkdir bitcoin-address cd bitcoin-address vi index.html i $address You will see a lot of “~” in the terminal. Don’t worry. It’s supposed to be like that.
6 Hit the escape key.
7 Type :wq and hit enter key.
8 Type python -m SimpleHTTPServer 8000 and hit enter key. In case you should have to restart this web-server you will have to do it from the "bitcoin-address" directory created in step 5. want to use alternative port?
9 Now go back to your router configuration page and set it to forward port 80 to $localip port 8000. Beware, $localip is not your public IP which you have found out in step 3 but the subnet IP of the machine you run your node on which you have found out in step 1.
10 Confirm steps 5-9 worked by using a different internet connection (e.g. 4g on your phone) and type $ip in the address bar. You should see a simple webpage with only your Bitcoin address on. If you see that, you are set to go on.
11 Activate your node by opening your web browser and entering https://bitnodes.21.co/nodes/$ip-8333/ in the address bar. Beware of the $ip you have to replace with your specific parameter.
12 Open a new terminal and copy paste sudo apt-get install curl and hit enter key. You will be asked for your root password to do this step.
13 Open a new terminal and copy paste this:curl -H 'Accept: application/json; indent=4' -d 'bitcoin_address=$address' -d 'url=http://$ip' https://bitnodes.21.co/api/v1/nodes/$ip-8333/ Beware of the $address and $ip (2x) you have to replace with your specific parameters. There is a "success": true message in the terminal after this step.
14 Open your browser on the system with runs your node and the following in the address bar: https://bitnodes.21.co/api/v1/nodes/$ip-8333/ Beware of the $ip you have to replace with your specific parameter. Url and bitcoin_address parameters should not be empty. If you wait ten minutes and reload the page you should also get "verified": true. This means you are now in the node incentive program. Any incentives will be payed to your Bitcoin address, shall you receive any. I think it depends on luck.
15 Open your browser on the system which runs your node and the following in the address bar: https://bitnodes.21.co/nodes/$ip-8333/ Beware of the $ip you have to replace with your specific parameter. Alternatively just reload the page from step 11 if you still have it open. You can now see some statistics for your node plus you should also be able to see it’s Bitcon address and verification url.
16 You can see where your node is in the leaderboard by entering this into the address bar of your browser: https://bitnodes.21.co/nodes/leaderboard/?q=$ip Beware of the $ip you have to replace with your specific parameter. You can now see the PIX rank of your node. It needs to be above 8 to have your node successfully in the ballot. PIX rank explanation given on the site.
Thanks to bitnodes.io, Addy Yeow and AndrewToth for helping me out to set up my own incentivized node.
Now I wish you all the best! Please tell me if it works, I will be back later to answer questions or correct things.
Edit1: I have done lots of formatting updates. Added Point 14 16.
Edit2: Added steps proposed by Explodicle. Installation of curl and activation of node at bitnode.io.
Edit3: Added the dedicated folder for web-server index.html
Edit4: Alternative port options added as suggested by n00tz.
Edit5: Awesome script added to top section. All props to Explodicle.
Edit6: Changed instructions and the script to work with new address "bitnodes.21.co" instead of "getaddr.bitnodes.io"

DECENT MINING SETUP & RESSOURCES SHORTCUT

To all DECENTants,
I would like to encourage you to become a seeder or witness (actually not miner) on DECENT.

SHORT INTRODUCTION ABOUT ME

As a pioneer with Bitcoin I truly believed in the DCT project and it's proposal. The first day of the ICO release I sent all my BTC balance to the DECENT. Not knowing when and what they will deliver. To participate in this great adventure means a lot to me. Another project from my home country I strongly encourage you to get familiar with is Ethereum. I have been an early CPU miner: before Crypto Currency I used to compute for sience projects grid for Clean Water and Cancer Research. If I hadn't bought Rainforest with the Ripple they distributed to all contributors, I'd be a rich man today. :P

I - SERVER SETUP

A dedicated server with Linux Ubuntu 16.04 LTS is most recommend for 24/7 operation. I suggest you close the root and create a new user with SSH Key, secure the system with a firewall.

1. Create a new user

adduser bob 

2. Elevate him

usermod -aG sudo bob 

3. Generate a new keyset

ssh-keygen 

4- Bind the new keys

ssh-copy-id [email protected]_server_ip 
Copy the keys to your local drive. You'll need them to connect.

5. Change the config file

sudo nano /etc/ssh/sshd_config 
Change Line PasswordAuthentication no

6. Finish with

sudo systemctl reload sshd 

7. Login with your ssh key, user and password

ssh [email protected]_server_ip 

II - PREREQUISITES

1. Grab your tools

sudo apt-get update sudo apt-get install build-essential autotools-dev automake autoconf libtool make cmake checkinstall realpath gcc g++ flex bison doxygen gettext git qt5-default libqt5svg5-dev libreadline-dev libcrypto++-dev libgmp-dev libdb-dev libdb++-dev libssl-dev libncurses5-dev libboost-all-dev libcurl4-openssl-dev python-dev libicu-dev libbz2-dev 

2. Download and build Boost 1.60.0

mkdir -p ~/dev/DECENTfoundation/DECENT-Network-third-party cd ~/dev/DECENTfoundation/DECENT-Network-third-party rm -rf boost_1_60_0* boost-1.60.0* wget https://sourceforge.net/projects/boost/files/boost/1.60.0/boost_1_60_0.tar.gz tar xvf boost_1_60_0.tar.gz mkdir boost-1.60.0_prefix cd boost_1_60_0 export BOOST_ROOT=$(realpath ../boost-1.60.0_prefix) ./bootstrap.sh --prefix=$BOOST_ROOT ./b2 install cd .. rm -rf boost_1_60_0 boost_1_60_0.tar.gz 

III - INSTALLATION

1. Clone the repo

mkdir -p ~/dev/DECENTfoundation cd ~/dev/DECENTfoundation #via ssh $ git clone [email protected]:DECENTfoundation/DECENT-Network.git #via url $ git clone https://github.com/DECENTfoundation/DECENT-Network.git cd DECENT-Network git submodule update --init --recursive 

2. Build and install Decent

mkdir -p ~/dev/DECENTfoundation/DECENT-Network-build cd ~/dev/DECENTfoundation/DECENT-Network-build cmake -G "Unix Makefiles" -D CMAKE_BUILD_TYPE=Debug ~/dev/DECENTfoundation/DECENT-Network cmake --build . --target all -- -j -l 3.0 cmake --build . --target install 

IV - USE DECENT

You don't want your server to shut down the process when you lose connection or quit.
I use tmux. Though nohup is sufficient for infrequent access. Use it when you fire up decentd after miner setup.
nohup ./decentd & disown 

1. RUN decentd - On first run decentd will create .decent in the home directory.

~/dev/DECENTfoundation/DECENT-Network-build/artifacts/prefix/bin/decentd 
Always close it via Ctrl+C to save the current state Ctrl+S Freeze Ctrl+Q Resume

2. Get HELP

cd ~/dev/DECENTfoundation/DECENT-Network-build/artifacts/prefix/bin/ ./decentd -h 

3. RUN cli_wallet

~/dev/DECENTfoundation/DECENT-Network-build/artifacts/prefix/bin/cli_wallet 
Close it with Ctrl+D

4. USE cli_wallet

set_password xy unlock xy 

5. IMPORT your account

import_key decentgo_username your_private_key 

6. CREATE 3 sets of keys for your new account

suggest_brain_key 
write them down, don't use the ones below. ;)

1. new owner key

{ "brain_priv_key1": "UNBUSH ROAR CHKALIK STRUE PLATTEN DEMOB COLETIT DECAYER SPERONE SPASMED ANATASE LAGGARD BESPETE AXOID SERAL CHEKI", "wif_priv_key1": "5J4brX9bydADigEtsXZhCZ1YLVXkq8frp4xcKAREQ3Gh3P2DE7e", "pub_key1": "DCT5VNJni7HypYi159qiwazZ1WZUt4p2v7NLQmFCJPDvjBpW2oG8a" } 

2. new active key

{ "brain_priv_key2": "FUSION BLART JAIL FESTAL LAXNESS ROSTEL TITI VANADYL PUG BATATA KAIK ROSETY STUCCO TETE BEMUDDY WUDGE", "wif_priv_key2": "5HvsjRsokHSeeUdRkM88JgLzYJ6vnc2e35CzyZNRnmh1fvm91Jz", "pub_key2": "DCT7G7KeUnMPVKXN2y8M7BnyosLRE3LtSnNp7kbxtYd9xHiBoX6wd" } 

3. new public signing key

{ "brain_priv_key3": "DECESS LABBA PLAN DEHUSK FISTY MOSSER SPURTER SCORIAE INDART UNDYE MASTER STEIGH SAFROLE FLURR THAPSIA JOB", "wif_priv_key3": "5JgMsecySgt2BQsmmEE9QnwAGuudC9fGeZJhreyPatcu2TVY9bs", "pub_key3": "DCT6D7TLeVJmPQWR73XHvEhTVHzTDoG6oTSUyvfGa58nuc5wL96UH" } 

7. CREATE your new account

register_account new_username pub_key1 pub_key2 decentgo_username true 

8. SEND some DCT to your new account

transfer decentgo_username target_username 3.00 DCT "memo" true 

9. IMPORT the new account

import_key new_username wif_priv_key2 

10. Close the Wallet and edit the config.ini inside /root/.decent/data/decentd/

private-key = ["pub_key2","wif_priv_key2"] 

11. Launch again and create your miner

create_miner username "proposal URL" true 

12. Change your signing key to 3rd keypair from suggest_brain_key

update_miner username "proposal URL" public_key3 true 

13. Edit the config.ini again inside /root/.decent/data/decentd/

enable-stale-production = true miner-id = "1.4.X" private-key = ["pub_key3","wif_priv_key3"] 

Your Server is now ready to run a DECENT witness.

Be aware that you should not close your daemon at any time.

V - USEFUL COMMANDS

get_brain_key_info dump_private_keys get_private_key public-key get_account texxi get_miner texxi list_my_accounts list_account_balances texxi set_desired_miner_count username 99

How to set up a Bitcoin full node on Linux VPS (pruning node)

This tutorial is for Linux Debian based OS (Ubuntu) at least with 1GB of RAM and 20 GB SSD. There are a few guides out there about how to set it up..but still not good enough. My Bitcoin Segwit node now is running on my VPS (yes I know it's not the best option but still..) I found few articles.. Due to these articles I’ve kept the below quite brief.
Please note: Before you start.. Your server may still be finishing installing and booting up during the first few minutes of activation. In this tutorial i'm using Linux Ubuntu 16.04 x64 LTS.
Secure VPS server (Firewall rules)
Command may disrupt existing SSH connection. Proceed with operation (y|n) ? Type y and hit ENTER.
Install the Bitcoin Core daemon (bitcoind)
Press ENTER to continue
Do you want to continue? Type y and hit enter.
Create a Bitcoin user
Enter new UNIX password (whatever you want) and then it will ask for your full name, room number, work phone, home phone, other (press the Enter key to skip). Is the information correct? Type y and hit ENTER.
Set up log rotation
Enter into it:
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Configure Bitcoin
Add to the file:
prune=550
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Press CTRL+D to log out of the Bitcoin
Configure swap space
The node we created only has 1GB so we’ll make some spare “virtual memory” using swap space.
Add this line at the end of the file:
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Set up the Bitcoin daemon to auto-run.
Enter into it (copy paste this):
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Reload systemd and start bitcoind:
You can use https://bitnodes.21.co/nodes/ to check if your node is running! If there is something wrong, please let me know that. I'm still learning ;)

Run a Tor Node for $10 Per Year

I'm posting this just as much for my benefit as for everyone else's (so I can refer to it in the future), but this is the be-all-to-end-all on getting it set up easily and quickly.
The Steps
1) Sign up for an account at berry.pw. Buy the one for $10 a year. When it asks for details like hostname and stuff, just enter random data like google.com. Remember your root password though.
2) Choose Ubuntu 14.04 LTS Server as the installation OS. Even if a newer version is released by the time you do this, don't use it. Just wait and use this version, because it is guaranteed to work.
3) Check your email for the login details. I wasted 4 hours talking to tech support (which is sub-par, but you should never have to talk to them if you follow these instructions) because of this: check your spam/junk folder. In the past, this has never happened on Gmail with me, but this email ended up wrongfully in the Junk folder.
4) In the email you got (subject: New Virtual Server Information), record the IP address titled "Main IP", and verify that the root password is correct.
5) Log into your server via SSH. On a Mac or Linux computer, run "ssh [email protected] IP", and enter your root password. On a Windows computer, look up how to log into an SSH server via "Putty".
6) Run "lsb_release -c" and remember what the Codename Output is (it should be "trusty", but if you installed a different version of Ubuntu, then just remember what that output says).
7) Run "apt-get install nano curl fail2ban". fail2ban is for protection to prevent brute for attacks. If you don't want this protection, you can just remove that word. I recommend you leave it, but it automatically blocks your IP if it is making too many requests to the server. To remove it later, run "apt-get remove fail2ban".
8) Run "nano /etc/apt/sources.list"
9) At the bottom, add the following line: deb http://deb.torproject.org/torproject.org trusty main
9a) If the Codename from 4 steps ago wasn't "Trusty", replace "trusty" in the above step with what ever it said, in all lower case.
9b) Exit nano by: Press Control-X, press enter, press Y, press enter.
10) Run the following commands one-by-one. If any give an error, comment to this post and I'll try to help.
gpg --keyserver keys.gnupg.net --recv 886DDD89 gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add - sudo apt-get update apt-get install deb.torproject.org-keyring apt-get install tor 
11) Run "nano /etc/totorrc". Make the following changes by typing Control-W to search for keywords in the following changes (same as Find function in any modern text editor)
11a) Remove the "#" in front of each of the following lines:
#ORPort 9001 #DirPort 9030 #ExitPolicy accept *:6660-6667,reject *:* # allow irc ports but no more #ExitPolicy accept *:119 # accept nntp as well as default exit policy 
11b) You can change the numbers after ORPort and DirPort to 443 and 80 if you want to help people behind firewalls (optional step).
11c) At the bottom, add the following line:
ContactInfo [an email address that can handle spam without brackets] - [Bitcoin Address if you have one for donations without brackets] 
11d) Press Control-X, press enter, press Y, press enter.
12) Run "service tor reload".
13) View the log by running "cat /valog/tolog". You can run this in the future to view the log and make sure everything is working fine.
13a) However, there's an easier way to test the server. Go to this port checker, type in your main IP from the email at the beginning of the tutorial, and enter 9001 in the port box. Press enter, make sure it's working. Then do it with port 9030. If those both work, you're all set! If not, post in the Reddit and we'll try to fix it.
13b) Further testing: After a few hours (give it a minimum of 6 hours), search for your IP at the Tor node lookup service. If it's not there, check to make sure the ports are forwarded. Post here for help if you'd like.
14) Enjoy helping the world! In 365 days, you'll see your PayPal account another $10 lighter. But it's all worth it.
Please donate with bitcoin and changetip if you like what I've done here. Thanks for reading.

Nginx - Reverse Proxy Port 3001 to 80 https://eladnava.com/binding-nodejs-port-80-using-nginx/
BiblePay Daemon set to run Every 2 Minutes with Cron
sudo crontab -e */2 * * * * /home/biblepay/src/biblepayd > /dev/null 2>&1 
Note: In ~/.biblepaycore/biblepay.conf add daemon=1 and txindex=1 Note: > /dev/null 2>&1 will capture both STDOUT (1) and STDERR (2) and send them to /dev/null
Auto Remove index.pid if indexing is complete
#!/bin/bash fname="/home/biblepay/exploretmp/index.pid" if [[ -f "$fname" ]]; then pid=$( /dev/null r=$? echo $r if [ $r -eq 0 ]; then exit 1 else rm $fname fi fi 
-f is checking if the file exists index.pid is the indexing lock file with its process ID number inside of it ps -p checks if the process is running $? is the value of the last output that ran and since the previous value is going to dev/null, its the exit code status "0 for successful executions and 1 or higher for failed executions." and so if the process is still running, the bash script just exits, otherwise the process is done and the index.pid file gets removed the file doesnt need a .sh extension, if you have "#!/bin/bash" at the top then linux knows its a bash script chmod +x to set it as executable

Use the BTCP full Node on a Ubuntu 16.04 LTS from Terminal

In this post I want to show some use of the CLI BTCP wallet from linux terminal.
DISCLAIMER:
First of all, use this tutorial with small amount of BTCP, for example i used 0,01 BTCP, until you feel confortable with commands. An error can happen easily and as result you can loose your money. Be careful! Do it at your risk!
I consider you have already installed the wallet following this instructions:
https://github.com/BTCPrivate/bitcoinprivate
I use Ubuntu 16.04 LTS 64bit, but commands are similar for the windows client.
Open a terminal from your Ubuntu Desktop:
[email protected]:~$ 
type:
[email protected]:~$ ./BitcoinPrivate/src/btcpd --daemon 
you should see the message:
BTCP server starting 
This means the wallet is running in daemon mode.
to stop the node just typing:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli stop 
Answer:
BTCP server stopping 
You can also run the wallet in terminal, is nice to see it, let's try:
 [email protected]:~$ ./BitcoinPrivate/src/btcpd 
You will see the BTCP logo in text mode and the following info:
Thank you for running a Bitcoin Private node! You're strengthening the network and contributing to a social good. To ensure you are fully protecting your privacy when running BTCP, see . Block height | 340079 Connections | 8 Network solution rate | 8359387 Sol/s You are currently not mining. To enable mining, add 'gen=1' to your btcprivate.conf and restart. Since starting this node 1 minutes, 33 seconds ago: - You have validated 695 transactions! [Press Ctrl+C to exit] [Set 'showmetrics=0' to hide] 
See, you can also mine using the wallet! Nice! Just add gen=1 in the file btcprivate.conf. Probably you will never mine a coin, but still you to strenght the net, so, you can try if you want, then disable it when done:
Press CTRL and C to stop the server, then restart the server in daemon mode otherwhise you have to open a new terminal.
Let's find btcprivate.conf and other useful files:
[email protected]:~$ cd .btcprivate [email protected]:~/.btcprivate$ ls 
Answer:
blocks btcprivate.conf chainstate db.log debug.log fee_estimates.dat peers.dat wallet.dat 
You see here: btcprivate.conf and wallet.dat
Edit configuration file:
[email protected]:~/.btcprivate$ pico btcprivate.conf 
add gen=1 if you want to mine, then CTRL X and Y to save.
Restart the wallet....and....
Block height | 340091 Connections | 8 Network solution rate | 8211926 Sol/s Local solution rate | 0.0075 Sol/s Since starting this node 8 minutes, 5 seconds ago: - You have validated 684 transactions! - You have completed 1 Equihash solver runs. You are mining with the default solver on 1 threads. 
Congratulations! You are mining!
Now have a look to the wallet.dat file:
Nb: wallet.dat is your wallet!! If you delete it you will loose all your money!!!
wallet.dat is not encrypted, so, if you want to backup it i do as follows:
[email protected]:~/.btcprivate$ cp wallet.dat home/btcp/Desktop/wallet_btcp_back.dat 
Now you will find the wallet on your desktop. Zip it with an AES256 encryption and a strong password. Test if it works properly: extract it again and copy it in the directory, but before make an other copy of the wallet.dat file. Beware! I almost deleted the file once!
Nb: wallet.dat is your wallet!! If you delete it you will loose all your money!!!
Go back to your home directory, now, we want to play with our wallet:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli help 
if everything is running properly, you will see a list of commands like this:
z_exportwallet "filename" z_getbalance "address" ( minconf ) z_getnewaddress z_getoperationresult (["operationid", ... ]) z_getoperationstatus (["operationid", ... ]) z_gettotalbalance ( minconf ) z_importkey "zkey" ( rescan startHeight ) z_importwallet "filename" z_listaddresses z_listoperationids z_listreceivedbyaddress "address" ( minconf ) z_sendmany "fromaddress" [{"address":... ,"amount":...},...] ( minconf ) ( fee ) z_shieldcoinbase "fromaddress" "tozaddress" ( fee ) zcbenchmark benchmarktype samplecount zcrawjoinsplit rawtx inputs outputs vpub_old vpub_new zcrawkeygen zcrawreceive zcsecretkey encryptednote zcsamplejoinsplit [email protected]:~$ 
Nice! Wallet is running properly. Now try an other command: getinfo
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getinfo 
Answer:
{ "version": 1001251, "protocolversion": 180004, "walletversion": 60000, "balance": 0.00000000, "blocks": 340074, "timeoffset": 0, "connections": 8, "proxy": "", "difficulty": 167290.7158221716, "testnet": false, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000, "relayfee": 0.00000100, "errors": "" } [email protected]:~$ 
You see some useful info about your wallet/node:
blocks is the block heights, in this case is synced with the network. If not the number would be lower.
The wallet is connected to other 8 nodes, the balance is 0.00 BTCP
An other info command can be getblockchaininfo:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getblockchaininfo 
Answer:
{ "chain": "main", "blocks": 340074, "headers": 340074, "bestblockhash": "0000000145c0011d8e914f4ba68d1443c7ae0dd15bdf0bc300994dd5282710aa", "difficulty": 165971.1181999981, "verificationprogress": 0.9999992572690658, "chainwork": "0000000000000000000000000000000000000000000000000002e8314e4484da", "pruned": false, "commitments": 663480, 
we see syncing is almost finished:
"verificationprogress": 0.9999992572690658, (99,99999%)
Now test the wallet with command getwalletinfo
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00000000, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 0, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } [email protected]:~$ 
Now we want to send some btcp to this wallet. First we need an address, get one using getnewaddress:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getnewaddress 
Answer:
b1Cabjwvcce7N8ea9Gxxxxxxxxxxxxxxxx [email protected]:~$ 
Send at this address some BTCP, i sent 0.01 for testing purpose using your ledger, or your wallet, then check if the transaction is done:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00000000, "unconfirmed_balance": 0.01000000, "immature_balance": 0.00000000, "txcount": 1, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } 
Done! Unconfirmed balance is 0.01! Just wait some confirmations.
after a while:
"walletversion": 60000, "balance": 0.01000000, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 1, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 
Now send the coins to a new address. I am using this command:
sendtoaddress "btcpaddress" amount ( "comment" "comment-to" subtractfeefromamount )
subtractfeefromamount parameter can be true or false
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli sendtoaddress "b1Nb42GoK9kmsxxxxxxxxxxxxx" 0.01 "" "" true 
Answer:
2c5d3d1a3b5eec414b721d3817487f53c5eebxxxxxxxxxxxxxxx [email protected]:~$ 
Now check the wallet:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00999808, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 2, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } 
I sent BTCP to the same wallet, so now i have less BTCP because of the fees.
try more commands:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listreceivedbyaddress 
Answer:
[ { "address": "b1Ep2wi2tUnKf433Vaxxxxxxxxxxxx", "account": "", "amount": 0.01000000, "confirmations": 6, "txids": [ "833533440a13c09fda6e90d0c5xxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ] }, { "address": "b1Nb42GoK9kmsVZ9KPxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "account": "", "amount": 0.00999808, "confirmations": 1, "txids": [ "2c5d3d1a3b5eec414b721d3817487f53c5xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ] } 
This is the list of all used addresses.
Now find the money and the address where they are: use listunspent
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listunspent 
Answer:
[ { "txid": "2c5d3d1a3b5eec414b721d381748xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "vout": 0, "generated": false, "address": "b1Nb42GoK9kxxxxxxxxxxxxxx", "account": "", "scriptPubKey": "76a914c6bdf3bc8aedxxxxxxxxxxxxxxxxxx", "amount": 0.00999808, "confirmations": 6, "spendable": true 
Well done.
Other useful commands can be: dumpprivkey to extract the private key from an address
Be careful! Exposing your private keys will end in loosing your money
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli dumpprivkey b1Ep2wi2tUnxxxxxxxxxxx 
Obtaining the pvt key:
Kz29e62Bmxxxxxxxxxxxxxxxxxxxxxxx 
And now, swipe the private key using the command: importprivkey "btcpprivkey" ( "label" rescan )
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli importprivkey "Kz29e62Bmxxxxxxxxxxxxxxxxxxxxx" "" true 
Let's do a shielded transaction!
first, you must have a z_address:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_getnewaddress 
Answer:
zkEvCiVwgHb3NFi2ee9HGPjno2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 
Check balaces, with also z_addres:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_gettotalbalance 
Answer:
{ "transparent": "0.00999808", "private": "0.00", "total": "0.00999808" } 
Now send some BTCP to the z_address. First, check where BTCP are:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listunspent 
Output:
[ { "txid": "72f568d1ed51524b69f1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "vout": 0, "generated": false, "address": "b1LDhxBJxxxxxxxxxxxxxxxxxxxxxx", "scriptPubKey": "76axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxe088xx", "amount": 0.00889808, "confirmations": 556, "spendable": true } ] 
Now, sent a little transparent amount to the shielded address we got before:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_sendmany "b1LDhxBJxxxxxxxxxxxxxxxxxxxxxx" "[{\"amount\":0.001, \"address\":\"zkEvCiVwgHb3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\"}]" 
Output:
opid-xxxxxxx-36c4-xxxx-beb2-xxxxxxxxxxxx 
Now your PC will work a while, it's CPU consuming...so...check:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_getoperationresult 
until you receive the answer:
[ { "id": "opid-xxxxxx-xxxxx-4a5d-beb2-xxxxxxxxxx", "status": "success", "creation_time": 1529426885, "result": { "txid": "f87e8d5e96a8a0xxxxxxxxxxxxxxx" }, "execution_secs": 216.686332567, "method": "z_sendmany", "params": { "fromaddress": "b1LDhxxxxxxxxxxx", "amounts": [ { "amount": 0.001, "address": "zkEvCiVwgHb3NFxxxxxxxxxxxxxxxxxxR" } ], "minconf": 1, "fee": 0.0001 } } ] 
Done! On my old PC it took 216.68 seconds!
Next will be a reverse operation, from Shielded address to transparent address. See you soon....
Play with your full node wallet and have fun.
Remember: these commands are almost the same in all the bitcoin based coins, so you also learnt how to use many other wallets!

Odd Bitcoin Virus

So I decided to play around with bitcoin today. Started my own QT server, sent myself a few coins and used a plugin python script to verify that my wallet received them, used a tutorial to start my own bitcoinj server, and this is where things got weird. My razer keyboard's firmware stopped working. At first, I assumed that it was the driver so I deleted it by hand, no good, plugged it back in, still sending odd keys. After that I immediately took my computer offline and tried the keyboard on another throw away box that I have, same problem. In fact, it added a new exe (!) to razer's driver directory on my Windows machine (I was originally on Ubuntu). This keyboard had already been connected to that machine, it wouldn't have installed a new exe on connecting. So apparently connecting yourself to the bitcoin core is not only not safe, it has some of the most advanced attackers that I've ever witnessed. I want to specify that this only seemed to happen when I used bitcoinj to download a shortened blockchain. I guess that when you have to trust peers for anything, you are at risk of downloading malicious material, but I really thought that the existing clients (such as bitcoinj) would be smart enough to check blockchain md5's or something to prevent this. Absolutely brutal introduction for an interested programmer.

[P2pool] How to make your own personal p2pool Node!

Tired of getting no block rewards and sending many dead shares? Need a p2pool node close to your miner? MAKE YOUR OWN! :D
And, Yep, P2pools give 0.5% Rewards to block finders!
Here's some info about p2ools: http://whatisp2pool.com/
The stronger the P2Pool network becomes the more resistant the digibyte network is to 51% attacks!
Oh and, P2pools are DDOS proof! Now that's News! So if your node gets DDOS'd .. you dont lose your shares as the shares have been saved in the p2pool, its called the sharechain. So you get paid anyhow! Thanks to the p2pool network. and you ccan set your workers to another pool using the "--failover only" command in cgminer (if im not wrong) and get it back to work on the p2pool network!
TL;DR; P2POOL = 1 Big fat network Decentrazlized pool!
STEPS TO MAKE A P2POOL:
Install Ubuntu server or Desktop if you want http://www.ubuntu.com/download/ or u can use a VPS (VirtualPrivateServer -- Link Below with coupon code)
So Let's start off in the command line (Open Terminal.. and all you have to do is Cut, Copy Paste! ;) )
Start by updating and upgrading Ubuntu, you know you want the best ;)
sudo apt-get update sudo apt-get upgrade sudo apt-get install python-software-properties sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update 
Time for the DigiByteProject dependencies!
sudo apt-get install build-essential libboost-all-dev libcurl4-openssl-dev libdb5.1-dev libdb5.1++-dev git qt-sdk libminiupnpc-dev sudo apt-get install qrencode libqrencode-dev 
And, Now to compile DigiByte on your system!
git clone git://github.com/digibyte/DigiByteProject.git digibyte #renaming makes it easier ;) cd ~/digibyte/src mkdir obj make -f makefile.unix USE_UPNP=- sudo cp digibyted /usbin cd ~ 
After it has compiled try running 'digibyted'
./digibyte/src/digibyted 
If you get an error saying you need to make the digibyte.conf file, good! :) If it doesnt give you that error, make sure you followed the compiling steps appropriately.
So, Lets create the conf file here...
cd .digibyte #edited from 'digibyted' .. fixed!! nano digibyte.conf 
Paste the following, CHANGING THE USERNAME AND PASS!! make sure to take note of both, you'll need these later!
rpcuser=CHANGEusername rpcpassword=ChangePassword daemon=1 server=1 rpcport=14022 port=12024 gen=1 rpcallowip=127.0.0.1 addnode=74.208.230.160 addnode=31.220.25.91 addnode=184.155.218.183 addnode=24.119.23.61 addnode=70.196.193.231 addnode=198.98.118.241 addnode=142.4.204.115 addnode=23.90.191.58 addnode=216.250.125.121 addnode=115.28.31.25 addnode=83.172.105.46 
Press 'CTRL' + ' X', and then 'Y' to save when prompted
cd ~ ./digibyte/src/digibyted ./digibyte/src/digibyted getinfo 
Make sure you check the latest block in the block chain or on your local DigiByte Wallets. This is to see how far your p2pool node has gotten! This is gonna take quite a while so lets CONTINUE!
Let's get the p2pool software and frontend in! Install the p2pool dependencies!
sudo apt-get install python-zope.interface python-twisted python-twisted-web git clone https://github.com/Rav3nPL/p2pool-rav p2pool #renaming it! cd ~/p2pool/digibyte_subsidy #Thanks to Chaeplin sudo python setup.py install 
Time to edit and customise the html code to personalise your p2pool's frontend. Feel free to change the p2pool name and if you're an advanced user, feel free to add your own frontend from git hub after removing the web-static folder. (OPTIONAL: by using rm -f -r web-static #in that directory. And then you can choose whichever frontend you want! by cloning it in the web-static folder)
Editing the current frontend html!
cd .. cd web-static nano index.html 
After personalising the page, i.e. changing the p2pool name and adding some info! Lets go back and check how far the block downloading has gotten! You can check this by typing this in the command line after going back to the root directory:
cd ~ ./digibyte/src/digibyted getinfo 
This is gonna take a while so might as well check for updates again :P
sudo apt-get update sudo apt-get upgrade 
After making sure that all the blocks have been synced locally! We're ready to run the p2pool node! Simply enter the string below in the command line, entering your USERNAME and PASS that you saved earlier!
screen -d -m -S myp2pool ~/p2pool/run_p2pool.py --give-author 0 --net digibyte NEWUSER NEWPASS --outgoing-conns 4 
If you want to charge a fee for your node add this to your string, adding your fee address!:
--fee 1.0 --address NEWDGBADDRESS 
To see if the node is up and running enter this in the command line:
screen -x myp2pool 
'CTRL' + 'A' + 'D' to close the terminal if you press 'CTRL' + 'C', it will terminate the p2pool program and you'll have to restart the pool by using the string above!
Once, Everything is setup as planned! Check your p2pool node's ip Address by entering this into the command line:
ifconfig 
inet addr: 192.168.1.1 #You'll see a line like this.
So, Your cgminer string should look something like this:
cgminer --scrypt -o 192.168.1.1:9022 -u DGBADDRESS -p x
And your p2pool WEB ADDRESS should look like this:
192.168.1.1:9022
example: http://192.168.1.1:9022/
You can monitor your p2pool using that web address! Enjoy, your personal p2pool node!! :D
If for whatever reason the server shuts off and you need to restart the p2pool node, you should run digibyted again and after it has synced successfully, just type in your p2pool string:
./digibyte/src/digibyted
screen -d -m -S myp2pool ~/p2pool/run_p2pool.py --give-author 0 --net digibyte NEWUSER NEWPASS --outgoing-conns 4 --fee 1.0 --address NEWADDRESS
PRESS CTRL + A + D to Detach from screen
UPDATE Follow Guide below if you used this guide before DigibByte v2.0 was released (28th Feb 2014)
You must check whether you're on the right ShareChain. Make Sure the block Value says 7960!

Installing OpenBazaar on Raspberry Pi 3 (Raspbian "Jessie") Is A Pain - and does not work

Hello, hope to get help in this Bitcoin community which should have the main users of OpenBazaar.
I cannot get this run. Installing on Ubuntu or Linux Mint is utmost simple with the downloadable debian packages (*.deb).
In short:
For the Raspberry Pi (Raspbian Linux) I find various different tutorials on the web, all of which are somehow different and incomplete and of different age (so not sure what Openbazaar and what Raspbian version they refer to). I get one error after another. After several hours I am giving up now. I have installed so many other packages that are allegedly required for OpenBazaar (in one tutorial or another)... but it still does not work.
Not to mention the need to separately install the OpenBazaar Server and Client and the different configuration options, and no tutorial that really explains everything in a proper way how all components work together and what to do depending on the use-case.
This is a shame. OpenBazaar should FIRST run on the Raspberry, because the Raspberry is a low-power-consumption device that can run 24/7 with an electricity bill of only 5-10 EUR per year. And OpenBazaar as a decentralized marketplace is designed for exactly this mode of operation - always online! No way would I use a normal computer for this.
Has anybody successfully managed to install OpenBazaar (1.1.3) on "Raspian Jessie"?
Is a tutorial available that really works completely? Or even better, a debian package?
Actually I was inspired buying a Raspberry Pi because of OpenBazaar in the first place, and now I am stuck.
A good tutorial should include best practice recommendations on all parts, including:
Finally, what I am desperately missing is information how to backup and restore OpenBazaar configurations and move them from one computer to another. For example, I have installed OpenBazaar on my Linux Mint PC some weeks ago and created an account and a listing already, of course with OpenBazaar ID. Needless to say that now that I install OpenBazaar on my Raspberry, I want to use the same account there (instead of on my computer), such that information is not lost.

[TUTORIAL:] Creating a custom wallet. Part 1: Proof of concept.

Download and view this tutorial on GITHUB
I'm teaching myself the technical aspects of Bitcoin. I decided to start by making a custom wallet. Here is my quick and dirty proof of concept using Python, bitoinrpc, and PyQt.
So far, this only queries bitcoind for getinfo. It's only a stepping stone to the greater application.
I'll make more tutorials as the program develops. Please feel free to comment and ask questions. Keep in mind, Python isn't my primary language. I decided to go with Python only because I could use the practice.
I wrote this using Linux. It should work on Windows / Mac, but your mileage may vary. To use this, you are going to need Python 2.7 installed on your machine (obviously) as well as the dependent libraries: PyQt, Python bitcoinrpc, and json. Copy and paste the code in a file somewhere and run
$ python  
Change "rpc_username" and "rpc_password" to match that of ~/.bitcoin/bitcoin.conf
Make sure ./bitcoind -server is running
If everything is set up correctly you should see a gui app appear with the same information as if you were to run bitcoind getinfo from the command line.
#!/usbin/python # -*- coding: utf-8 -*- import sys from PyQt4 import QtGui from bitcoinrpc.authproxy import AuthServiceProxy import json class Configuration(): def __init__(self): self.protocol = "http" self.username = "rpc_username" self.password = "rpc_password" self.ip = "localhost" #self.port = "18332" self.port = "8332" def get_uri(self): self.uri = self.protocol+"://"+self.username+":"+self.password+"@"+self.ip+":"+self.port return self.uri class Command(): def __init__(self): self.conf = Configuration() self.access = AuthServiceProxy(self.conf.get_uri()) def get_info(self): self.info = self.access.getinfo() #self.info = self.access.listaccounts() return self.info class UI(QtGui.QWidget): def __init__(self): super(UI, self).__init__() self.init_ui() def init_ui(self): command = Command() info = command.get_info() keys = info.keys() label = [] line_edit = [] for (i, key) in enumerate(keys): label.append(QtGui.QLabel(str(keys[i]))) line_edit.append(QtGui.QLineEdit(str(info[keys[i]]))) grid = QtGui.QGridLayout() grid.setSpacing(10) for (i, item) in enumerate(label): grid.addWidget(label[i], i, 0) grid.addWidget(line_edit[i], i, 1) self.setLayout(grid) self.setGeometry(300, 300, 350, 300) self.setWindowTitle('getinfo') self.show() def main(): app = QtGui.QApplication(sys.argv) ex = UI() sys.exit(app.exec_()) if __name__ == '__main__': main() 
Features of note:
In the future I may just link to a github account. Time permitting.
Let me know what you think. Thanks!

How to receive bitcoin with Electrum?

I created a wallet, and sent the coins to the first Receiving address. Nothing has happened.
The bottom of the window shows "Not connected".
Does it need to connect to receive the bitcoins? How to connect? I don't see any menu item "Connect". I found no documentation about connecting.
I chose the Network menu selection, which does nothing.
Why is there no documentation or tutorial that explains the absolute basics?
EDIT: I tried installing on Ubuntu, and it failed to connect to the first server.
After choosing a different server, it worked on Ubuntu. But the network panel won't open on Mac.

[WTS] Nuxified.org, 8 years old, PR5 Web Site on Linux & Free Open Source Software

Nuxified.org was launched in December 2005, domain registered in June 2005, to be a tech support community for Linux and Free Open Source software with related articles such as editorials, reviews, and tutorials. It gathered a small community of active participants and contributors, and had a number of high traffic articles.
Around 2010 development wound down due to too much time being taken away from my then new job. In 2013 I planned a revival with a streamlined concept, but ultimately realized it would take me too much time considering I have other projects to work on.
Traffic
Currently the site receives about 2600+ uniques per month. Google Analytics verified is somewhat lower as I've re-added Google Analytics only recently. I've always used StatCounter.
Monetization
It mainly made money from text ad sales, through agencies and directly. I've included statistics from LinkWorth, but there were many more transactions through direct customers and via Text-Link-Ads.com where it made between $10 and $78 per month between July 2006 and November 2011. Earnings later diminished due to lack of engagement with it on my part.
However, the earnings potential is definitely there with the same methods as well as with better integration of adsense in combination with continued active development of content. All of the decent open source related content can be easily approved and published at LXer.com, a popular Linux and Open Source news site, which ensures a steady stream of new traffic.
A conservative estimate of potential earnings, based on the past, and the potential for its future, would be around $80. All it would take is a couple of links per month on LinkWorth, and only four per-year links with advertisers directly to achieve this, plus whatever extra is made on adsense. The only reason it is currently without revenue is that not enough time could be put into it.
Suggestion:
Start adding new articles such as reviews, tutorials, or commentary regarding anything Open Source. Specifically this can involve open source applications on Windows and Mac OS X, articles about Android and Android apps, and of course articles about various Linux operating systems such as Ubuntu and Fedora. Given the open source nature of Bitcoin that can also be one of the topics covered on the site. Just one article per week published through Open Source news sites such as LXer.com can go a long way in significantly increasing traffic, and making the site even more attractive to new advertisers.
Tech
Nuxified.org currently uses an installation of Drupal 6 with a custom designed template, and a custom set of plugins for its current functionality.
It is hosted on my VPS on a Lighttpd server and with MariaDB database (backwards compatible clone of MySQL).
What is included
Handover
If you desire to keep the site on the current server I will provide the SSH/SFTP login information. Domains will be transferred as well to your registrar account.
If you want to move the site to your web host I will provide SQL and file data and provide any assistance with the transfer. I'll provide current login information in the mean time as well, immediately after sale, and of course, domain transfers.
Depending on the final sale price I may also provide some assistance with the content clean-up / auditing so the best quality is highlighted. If you want to archive the forums or turn best posts into articles I can help. If you want to switch the site to WordPress I can help, within my means, to make sure that key functionality is kept or replicated, existing URL's preserved, and so on.
Stats
If you have any specific questions feel free to ask. You can also contact me on Skype ID "memenode".
I'm hoping for about 2 BTC. Reserve on my Flippa auction was $1500, and I have three potential buyers with one concrete offer of $800, but I wanted to see if I can get more before I pick the final buyer, plus I'd love to get paid in BTC!
Ownership verification
I've uploaded a text file to the site referring to this sale: http://www.nuxified.org/bitmarket_sale.txt and http://www.nuxified.com/bitmarket_sale.txt
If interested please PM me and I'll provide my bitcoin address.
