Running a QRL node on a Raspberry Pi

Running a QRL node strengthens the network, supports the decentralization and further verifies transactions on the network.

This project is a PoC developped during the QRL Winter Hackathon 2021.

Node setup

1. Download and flash Raspberry Pi OS.

   • Tests were done with Raspberry Pi OS with desktop (with the Rapsberry Pi imager, choose Raspberry Pi OS (32-bit))

2. Boot the Raspberry Pi and connect to a network.

3. Open a terminal and download the installation script. Make the script executable.

    $ wget https://raw.githubusercontent.com/0xFF0/QRL_rpi/main/Install_qrl_node_pi.sh
    $ chmod +x Install_qrl_node_pi.sh
   

4. Run the script (it takes approximatively 2 hours to setup everything).

    $ ./Install_qrl_node_pi.sh
   

5. When you’re done, you can start the QRL node.

    $ start_qrl
   

Models tested

This command was used to identify the pi model number: cat /proc/cpuinfo | grep 'Revision' | awk '{print $3}'.

Raspberry Pi tested are:

Revision	Model	RAM	Results
a21041	2 Model B	1 GB	Works
c03111	4 Model B	4 GB	Works
c03112	4 Model B	4 GB	Works
a02082	3 Model B	1 GB	Works
9000c1	Zero W	512 MB	Works
