This great How To PRE Node on Raspberry helps you to get installed a Preserve Node on your Raspberry Pi. A $PRE node helps not only the community, but also it helps you to earn $PRE.
PRE Node On Raspberry
WARNING:
- Before starting, you must consult your local authorities to find out if earning $PRE and installing a Preserve Node is in your country or state allowed. In case this is illegal or not allowed, then you must close this page without executing anything in the below blog
- This how to earn $PRE and providing the community with a Presearch note is neither a financial advise nor It is recommended in any way to invest any money into this experiment. Executing the below is fully on your own risk! In case you invest any money into this, than please be aware of the high risk of you losing all your money.
- You risk is to lose all your investments made into this, to be non-compliant to local regulations and you risk to destroy or harm your Raspberry Pi Computer (or any other computer you use for this).
- If you earn with this $PRE, then you must – if you have not already – immediately consult your local tax advisors and authorities to ensure you are fully compliant to local regulations and tax laws.

Index Of How To PRE Node on Raspberry
Background
According to the community, Presearch is a decentralized search engine powered by the community. Search privately, receive better results and get rewarded with the Presearch decentralized search engine, powered by blockchain technology.
The Presearch community says that a node is a computer contributing computing power to the presearch network. In exchange, you earn pre tokens.
The general assumption by the Presearch community is:
- Running a node is recommended on computers powered on 24/7 due to uptime score statistics.
- Installation or management of a node can be done over any operating system (Windows, Mac, Linux, other of your choice) as long as you can access the underlying docker application
- There is no limit for number of nodes one account could operate
- There is no preferred setup as the main goal of the project is to support decentralization
How To PRE Node on Raspberry
We run in three steps thru this.
- First, basic installation,
- secondly download and activation of the Presearch Node,
- and finally Autostart check
Basic Installation
First of all, ensure your system is up to date:
sudo apt-get update && sudo apt-get upgrade
Execute the below command:
curl -sSL https://get.docker.com | sh
This should output something that looks like this:
pi@raspberrypi3b:~ $ curl -sSL https://get.docker.com | sh # Executing docker install script, commit: e5543d473431b782227f8908005543bb4389b8de + sudo -E sh -c apt-get update -qq >/dev/null + sudo -E sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -qq apt-transport-https ca-certificates curl >/dev/null + sudo -E sh -c install -m 0755 -d /etc/apt/keyrings + sudo -E sh -c curl -fsSL "https://download.docker.com/linux/debian/gpg" | gpg --dearmor --yes -o /etc/apt/keyrings/docker.gpg + sudo -E sh -c chmod a+r /etc/apt/keyrings/docker.gpg + sudo -E sh -c echo "deb [arch=arm64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian bullseye stable" > /etc/apt/sources.list.d/docker.list + sudo -E sh -c apt-get update -qq >/dev/null + sudo -E sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -qq docker-ce docker-ce-cli containerd.io docker-compose-plugin docker-ce-rootless-extras docker-buildx-plugin >/dev/null + sudo -E sh -c docker version Client: Docker Engine - Community Version: 24.0.6 API version: 1.43 Go version: go1.20.7 Git commit: ed223bc Built: Mon Sep 4 12:31:36 2023 OS/Arch: linux/arm64 Context: default Server: Docker Engine - Community Engine: Version: 24.0.6 API version: 1.43 (minimum version 1.12) Go version: go1.20.7 Git commit: 1a79695 Built: Mon Sep 4 12:31:36 2023 OS/Arch: linux/arm64 Experimental: false containerd: Version: 1.6.24 GitCommit: 61f9fd88f79f081d64d6fa3bb1a0dc71ec870523 runc: Version: 1.1.9 GitCommit: v1.1.9-0-gccaecfc docker-init: Version: 0.19.0 GitCommit: de40ad0 ================================================================================ To run Docker as a non-privileged user, consider setting up the Docker daemon in rootless mode for your user: dockerd-rootless-setuptool.sh install Visit https://docs.docker.com/go/rootless/ to learn about rootless mode. To run the Docker daemon as a fully privileged service, but granting non-root users access, refer to https://docs.docker.com/go/daemon-access/ WARNING: Access to the remote API on a privileged Docker daemon is equivalent to root access on the host. Refer to the 'Docker daemon attack surface' documentation for details: https://docs.docker.com/go/attack-surface/ ================================================================================
Now, we our user called “docker” to the permissions group
sudo usermod -aG docker $USER && newgrp docker
Activation of the Presearch Node
First of all, we register to get a registration code. This is required, otherwise no way to get this work. For this, you need to have a Presearch account. If you do not have one, you will be requested to register. Otherwise, you leverage on existing your account and login with it.
Get the code by surfing to: https://nodes.presearch.com/dashboard
On this website, you can copy your registration code:
Presearch node registration code
Now, with this code, you can start docker and run your Presearch node by entering the below (replace $YOUR_REGISTRATION_CODE_HERE by your registration code that you copied in the above) :
docker stop presearch-node ; docker rm presearch-node ; docker stop presearch-auto-updater ; docker rm presearch-auto-updater ; docker run -d --name presearch-auto-updater --restart=unless-stopped -v /var/run/docker.sock:/var/run/docker.sock presearch/auto-updater --cleanup --interval 900 presearch-auto-updater presearch-node ; docker pull presearch/node ; docker run -dt --name presearch-node --restart=unless-stopped -v presearch-node-storage:/app/node -e REGISTRATION_CODE=$YOUR_REGISTRATION_CODE_HERE presearch/node ; docker logs -f presearch-node
NOTE: As written in the above, “REGISTRATION_CODE=$YOUR_REGISTRATION_CODE_HERE” in should become “REGISTRATION_CODE=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX”. The “XXXXXXXXXXXXXXX” are the code that you copied from https://nodes.presearch.com/dashboard.
The above command installs two services on your computer, the presearch-node and the presearch-auto-updater, and configure both of them to be always running in the background.
Once you executed the above successfully, then you will see something like the below on your screen:

2023-10-23T20:24:57.243Z info: Node is listening for searches...If you have this, than you can celebrate you made it run! The above command will run your Node in the background, even if you close your terminal window. It however will not run anymore, if you restart your system. To get this addressed, check the “Autostart” chapter.
In your Dashboard on https://nodes.presearch.com/dashboard you should now see your docker instance as running. Of course, depending on your setup, the internet situation, etc. it can take a while until you receive requests and can earn $PRE.
If you like to monitor what’s going on, you can check the logfile:
docker logs -f presearch-node
Autostart
In case you like to run your note automatically after restart, then you need to configure this. This chapter shows you how.
