Hardware Requirements

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

Step 1: Setting up Raspberry Pi OS

Download the latest Raspberry Pi OS (Rasbian Stretch Lite) from the official website: https://www.raspberrypi.org/downloads/raspbian/
Burn the OS to SD Card with Etcher.
Now, to enable SSH for the OS, access the boot partition of the SD Card.
```
sudo touch ssh
```
Enable WiFi connection.
```
sudo nano wpa_supplicant.conf
```

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>"
}

Now, insert the SD card into Raspberry Pi then power on.
Find the IP address from your router admin web panel.
Connect to Pi for the first time
```
ssh -p 22 pi@{IP-addresss}
```

Step 3: Hardening Raspberry Pi

Configure Pi locale, to prevent warning messages and compilation errors.
```
sudo raspi-config
```
Don't forget to edit the locale file too.
```
sudo nano /etc/default/locale
```

Add the following content.

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

Hardening security by adding a new user.

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

Then reboot Pi.
```
sudo reboot
```
Then connect back as the new user
```
ssh -p 22 <yourusername>@<ip-addresss>
```
And delete the default Pi user
```
sudo deluser pi
sudo passwd root
```

Step 4: Configure Raspberry Pi

Update Pi packages.

sudo apt-get update 
sudo apt-get upgrade

Reboot the system.
```
sudo reboot
```

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

Have a coffee, come back after 10 minutes.

Step 5: Install & Compile PRiVCY daemon

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
```

Run the script in background.
```
sudo nohup ./privcy-raspberry-pi.sh &
```
Come back after 2 hours.

Step 6: Setting up PRiVCY daemon for first-run

Setup PRiVCY.conf to connect to the correct node
```
nano ~/.PRiVCY/PRiVCY.conf
```

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).

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

Step 7: (Optional) Setting Startup Daemon

You can setup cron to automatically start PRiVCY daemon when system boot up.
```
mkdir ~/logs
sudo crontab -e
```
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
