The Bitcoin network thrives on decentralization, powered by participants like you. Beyond mining or trading, running a Bitcoin node is a powerful way to contribute to the network's integrity. This guide walks you through setting up a node using Bitcoin Core and Umbrel on a Windows 11 PC.
What Is a Bitcoin Node?
A Bitcoin node validates transactions and maintains a copy of the blockchain. Unlike miners, nodes don’t compete for block rewards but ensure the network remains secure and decentralized.
Key Features:
- Full Blockchain Storage: Requires ~500 GB of space.
- Validation Role: Verifies transactions independently.
- Decentralization Support: Strengthens network resilience.
Step 1: Setting Up Bitcoin Core
Prerequisites:
- A Windows 11 PC (macOS/Linux also supported).
- External hard drive (recommended for blockchain storage).
Installation Steps:
Download Bitcoin Core:
- Visit the official Bitcoin Core website and select the Windows executable.
Installation Setup:
- Choose a dedicated drive for blockchain data during installation.
- Enable pruning (optional) to limit storage usage (e.g., 100 GB).
Sync the Blockchain:
- Initial sync may take 2+ days. Ensure your PC remains powered on.
Completion:
- Once synced, your node is active and ready to validate transactions.

Step 2: Installing Umbrel
Umbrel offers a user-friendly interface with added apps (e.g., Lightning Network).
Prerequisites:
- Windows Subsystem for Linux (WSL) enabled.
Installation Steps:
Enable WSL:
Open Command Prompt as admin and run:
wsl.exe --install- Reboot your PC and set up Ubuntu credentials.
Install Umbrel:
In Ubuntu terminal, run:
curl -L https://umbrel.sh | bash
Access Umbrel Dashboard:
- Navigate to the local URL provided post-installation.
- Install the Bitcoin Node app and sync the blockchain.
Security:
- Enable a strong password and 2FA for node protection.

FAQ
1. Why run a Bitcoin node?
- Enhances network security and personal sovereignty over transaction validation.
2. Can I run a node on a Raspberry Pi?
- Yes! Umbrel supports Raspberry Pi for low-power setups.
3. Does a node earn Bitcoin?
- No, unless you also mine. Nodes validate but don’t mine blocks.
4. How much bandwidth does a node use?
- ~200 GB/month for initial sync; ~15 GB/month thereafter.
5. Is pruning safe?
- Yes, but reduces your ability to verify older transactions.
Final Tips
- Patience is key: Syncing the blockchain takes time.
- Security first: Always enable 2FA and strong passwords.
- Join the network: Your node helps keep Bitcoin decentralized.
