  • Not profitable on Raspberry Pi

We're building a node, not a miner!

Step-by-Step Setup Guide

Step 1: Install Raspberry Pi OS

Using Raspberry Pi Imager:

  1. Download from raspberrypi.com/software
  2. Choose: Raspberry Pi OS (64-bit) – Lite version recommended
  3. Configure advanced options:
    • Hostname: bitcoinnode
    • Enable SSH
    • Set username and password
    • Configure Wi-Fi (but use ethernet)
    • Set locale settings
  4. Flash to microSD card

Step 2: Initial System Setup

Boot and connect:

# SSH into your Pi
ssh username@bitcoinnode.local

# Update system
sudo apt update && sudo apt full-upgrade -y

# Install required packages
sudo apt install git curl wget screen htop -y

Optimize for Bitcoin node:

# Increase swap file size
sudo dphys-swapfile swapoff
sudo nano /etc/dphys-swapfile
# Change: CONF_SWAPSIZE=2048
sudo dphys-swapfile setup
sudo dphys-swapfile swapon

Step 3: Prepare External Storage

Connect and format SSD:

# Check connected drives
sudo fdisk -l

# Format the SSD (usually /dev/sda)
sudo fdisk /dev/sda
# Create new partition table and partition (follow prompts)

# Format as ext4
sudo mkfs.ext4 /dev/sda1

# Create mount point
sudo mkdir /mnt/bitcoin

# Get UUID for permanent mounting
sudo blkid /dev/sda1

Set up automatic mounting:

sudo nano /etc/fstab
# Add line (replace UUID with yours):
# UUID=your-uuid-here /mnt/bitcoin ext4 defaults,noatime 0 2

# Mount the drive
sudo mount -a

# Set permissions
sudo chown -R $USER:$USER /mnt/bitcoin

Step 4: Install Bitcoin Core

Download Bitcoin Core:

# Go to bitcoin.org and get latest version URL
cd /tmp
wget https://bitcoincore.org/bin/bitcoin-core-25.0/bitcoin-25.0-aarch64-linux-gnu.tar.gz

# Verify the download (optional but recommended)
wget https://bitcoincore.org/bin/bitcoin-core-25.0/SHA256SUMS
sha256sum --check SHA256SUMS --ignore-missing

# Extract
tar -xzf bitcoin-25.0-aarch64-linux-gnu.tar.gz

# Install
sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-25.0/bin/*

Create Bitcoin directory:

mkdir ~/.bitcoin

Create Bitcoin configuration:

nano ~/.bitcoin/bitcoin.conf

Add configuration:

# Current block count
bitcoin-cli getblockcount

# Network info
bitcoin-cli getnetworkinfo

# Peer connections
bitcoin-cli getconnectioncount

Monitor with script:

nano ~/check_sync.sh

#!/bin/bash

while true; do
    BLOCKS=$(bitcoin-cli getblockcount 2>/dev/null)
    HEADERS=$(bitcoin-cli getblockchaininfo 2>/dev/null | grep '"headers"' | awk '{print $2}' | sed 's/,//')
    
    if [ ! -z "$BLOCKS" ] && [ ! -z "$HEADERS" ]; then
        PROGRESS=$(echo "scale=2; $BLOCKS * 100 / $HEADERS" | bc -l)
        echo "Sync Progress: $BLOCKS / $HEADERS blocks ($PROGRESS%)"
        echo "Estimated time remaining: $((($HEADERS - $BLOCKS) / 100)) hours"
    else
        echo "Bitcoin Core starting..."
    fi
    
    sleep 60
done

chmod +x ~/check_sync.sh
./check_sync.sh

Step 7: Auto-Start Bitcoin Core
