Running the Zebra node software on a Raspberry Pi 4 allows you to participate in the Zcash network as an independent, consensus-compatible node. This guide will walk you through the steps to set up and run Zebra on your Raspberry Pi 4.

Prerequisites

  1. Raspberry Pi 4 (2GB RAM or higher recommended).
  2. MicroSD card (16GB or higher recommended) with Raspberry Pi OS (Raspbian) installed.
  3. Stable internet connection.
  4. Keyboard, mouse, and a monitor (for initial setup).
  5. SSH client (optional, for remote access).

Installation

  1. Update Your System Open a terminal or SSH into your Raspberry Pi and ensure your system is up to date by running:

    **sudo apt update**

    **sudo apt upgrade**

  2. Install Dependencies You’ll need to install some necessary dependencies for building and running Zebra:

    sudo apt install build-essential cmake git clang libssl-dev pkg-config

  3. Clone the Zebra Repository Open a terminal and clone the Zebra repository to your Raspberry Pi:

    **git clone <https://github.com/ZcashFoundation/zebra.git**>

    cd zebra

  4. Build Zebra To build Zebra, use the following commands:

    **cargo build –release**

    This process may take some time. Ensure that your Raspberry Pi is adequately cooled, as compiling can generate heat.

  5. Configuration Create a configuration file for Zebra. You can use the default configuration as a starting point:

    **cp zcash.conf.example zcash.conf**

    Edit the zcash.conf file to customize your node’s settings. You can specify the network, enable mining, set up peer connections, and more.

  6. Start Zebra You can now start Zebra with your custom configuration:

    **./target/release/zebrad -c zcash.conf**

    **git comment**

    This command will start the Zebra node, and it will begin syncing with the Zcash blockchain.

  7. Monitoring You can monitor the progress and status of your Zebra node by opening a web browser and navigating to **http://127.0.0.1:8233/status**.
