Staking [PRiVCY Coin] with Raspberry Pi

Hardware Requirements

1. Raspberry Pi 3 model B+ (1GB RAM)
2. 32GB MicroSD Card

Step 1: Setting up Raspberry Pi OS

1. Download the latest Raspberry Pi OS (Rasbian Stretch Lite) from the official website: https://www.raspberrypi.org/downloads/raspbian/

2. Burn the OS to SD Card with Etcher.
   

3. Now, to enable SSH for the OS, access the boot partition of the SD Card.

   sudo touch ssh
   

4. Enable WiFi connection.

   sudo nano wpa_supplicant.conf
   

5. Enter the following config

   country=GB
   ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
   update_config=1
   network={
    ssid="<wifi name>"
    psk="<wifi password>"
   }
   

6. Now, insert the SD card into Raspberry Pi then power on.

7. Find the IP address from your router admin web panel.

8. Connect to Pi for the first time

   ssh -p 22 pi@{IP-addresss}
   

Step 3: Hardening Raspberry Pi

1. Configure Pi locale, to prevent warning messages and compilation errors.

   sudo raspi-config
   

   

2. Don't forget to edit the locale file too.

   sudo nano /etc/default/locale
   

3. Add the following content.

   LANG=en_US.UTF-8
   LC_ALL=en_US.UTF-8
   LANGUAGE=en_US.UTF-8
   

4. Hardening security by adding a new user.

   sudo -i
   adduser <yourusername>
   adduser <yourusername> sudo
   

5. Then reboot Pi.

   sudo reboot
   

6. Then connect back as the new user

   ssh -p 22 <yourusername>@<ip-addresss>
   

7. And delete the default Pi user

   sudo deluser pi
   sudo passwd root
   

Step 4: Configure Raspberry Pi

1. Update Pi packages.

   sudo apt-get update 
   sudo apt-get upgrade
   

2. Reboot the system. 

   sudo reboot
   

3. Install the required libraries.

   sudo apt-get install git qt5-default qt5-qmake qtbase5-dev-tools build-essential libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libssl-dev libdb++-dev build-essential libtool autotools-dev autoconf pkg-config libssl-dev libboost-all-dev libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev autoconf openssl libssl-dev libevent-dev libminiupnpc-dev
   sudo apt-get install autotools-dev autoconf automake bsdmainutils build-essential git
   sudo apt-get install libtool libssl-dev libboost-all-dev pkg-config 
   sudo apt-get install libqrencode-dev libminiupnpc-dev libevent-dev libcap-dev libseccomp-dev
   

4. Have a coffee, come back after 10 minutes.

Step 5: Install & Compile PRiVCY daemon

1. The compilation for Raspberry Pi is not straightforward. Here's my handy script that:

   • Download the source for Github.
   • Compile required libraries.
   • Configure build files.
   • Compile daemon.
   • Copy daemon to home folder.

   You can check the content of the script here.

   wget "https://gist.github.com/stiucsib86/9eca3c814d5af2308d6d57f227d65f7f/raw/fed383f434d62dc5ae8ee214933f7c257c9d53c1/privcy-raspberry-pi.sh" -O privcy-raspberry-pi.sh
   chmod +x privcy-raspberry-pi.sh
   

2. Run the script in background.

   sudo nohup ./privcy-raspberry-pi.sh &
   

3. Come back after 2 hours.

Step 6: Setting up PRiVCY daemon for first-run

1. Setup PRiVCY.conf to connect to the correct node

   nano ~/.PRiVCY/PRiVCY.conf
   

2. Paste the following content.

   testnet=0
   listen=1
   server=1
   daemon=1
   maxconnections=90
   rpcuser=<YourIrrelevantUsername>
   rpcpassword=<YourIrrelevantPassword>
   rpcport=18580
   rpcconnect=127.0.0.1
   rpcallowip=127.0.0.1
   addnode=otwsvate4vvogbrt.onion:17770
   addnode=nufiijzpo7ac2k6u.onion:17770
   

   (Note: You should always double the check correct nodes from official Github Repo).

3. Copy your wallet.dat and paste in ~/.PRiVCY/ folder.

Step 7: (Optional) Setting Startup Daemon

1. You can setup cron to automatically start PRiVCY daemon when system boot up.

   mkdir ~/logs
   sudo crontab -e
   

2. Append the following:

   @reboot sudo -u <yourUser> /home/<yourUser>/PRiVCYd >> /home/<yourUser>/logs/crontab.log 2>&1
   

   Note: The last part is to send all output to a log file so you can check that if you still have problems

Step 8: Done!

1. Fire up PRiVCY daemon!

   cd ~
   ./PRiVCYd 
   

2. Happy staking!
   

3. Psst, don't forget to buy me coffee :D
