Raspberry Pi 4

Update May 2021: Brooklyn R kernel is now available, fully open source, customized specifically for Qortal, optimized performance, and a must-have! Brooklyn R was built specifically for Qortal and the data has proven it optimizes performance in virtually every aspect (blocks minted, computing, temperature, etc.) and drastically outdoes other images we’ve tried like Ubuntu 64 with the Crowetic scripts. 8gb is recommended over 4gb for those who haven’t purchased yet FYI!

Recommended : SD card 64GB minimum. Good quality Class 10. USB3 SSD 500GB and above.

Installation Instructions:

  1. Download and install Balena Etcher if you are on Linux/Mac OS or Win32diskimager for Windows.
  2. Download and install 7zip for your respective OS.
  3. Download the Brooklyn R image and extract the image using 7zip:https://github.com/Qortal/Brooklyn/releases
  4. Format the microSD card or SSD to fat32/fatx (microSD card we recommend using sd card formatter).
  5. Write the image to the microSD card/SSD and plug it into the Pi 4 when completed (power off on Pi 4).
  6. Power on the Pi 4 and wait a few minutes to start. In the mean time log into your router to see what the IP address is of your Pi 4 if you plan on going headless (ask Qortal tech for help finding your IP if you do not have access to your router). If you are using a monitor, keyboard and mouse ignore last.
  7. If you are going headless (using a different computer to log into the pi 4 desktop) then on windows open up Remote Desktop Connection. If on Linux or Mac download your version of windows remote desktop.
  8. Enter the IP for your Pi 4 and click connect. Click yes when it asks about connecting and if you trust the certificates.
  9. Log in. Username: pi Password: dmax911e
  10. Open the terminal and enter the command line: sudo raspi-config. Scroll down to advanced settings hit enter, select expand file system and select it. When it is done select exit and it will ask for you to reboot. Click yes.
  11. Move the tar file to the home folder, open up the terminal (called konsole on Brooklyn R) and type this command line: “tar -zxvf qortal.tar.gz”
  12. Once complete move the db.7z to the qortal folder and open the terminal and run these commands: “cd qortal” and “7z x db.7z”

When the db is done extracting and you see the [email protected] pop back up type “./run.sh”

Your core will start up and you should see a blue Qortal logo pop up.

How to Run Qortal UI

Type in Terminal:

cd UI

cd qortal-ui

yarn run server

Enter after each commands

Leave the window open just minimize it. Then goto the web browser chromium and type localhost:12388 Qortal UI Login will pop up.

BrooklynR Kernel features:

  1. Hardened the Kernel security. No more local exploits.
  2. Locked the memory copy b/w internal and external memory devices
  3. Added Entropy hardware for maxed out entropy. Far more than an i7 Processor.
  4. Thermal control. Yes you can add fans and they will auto start when the temp hits 51C
  5. SPH implementation of crypto functions
  6. Updated crypto algorithms
  7. Full SoC encryption enabled on board the CPU for UI and Core speedup

Crypto is now fully accelerated.

The Kernel version with this release is 5.12.6 hybrid. 32 is enabled by default. You will not need 64 bit. This release can guarantee uptime of years without a single reboot or stall. No one will ever need to reboot a Pi 4 anymore, provided you use the recommended power bricks. Able to mine Monero on it as well.

Users have option of Headless release or with a full featured accelerated Desktop GUI Release : Plasma, XFCE, or Cinnamon.
