Why run your own bitcoin node?

For bitcoin to function reliably and securely, it relies on the voluntary participation of thousands of individuals worldwide. Nodes, which make up the bitcoin network and verify transactions and blocks, are crucial to this process. There are many reasons to consider running your own bitcoin node, including personal benefits and the benefits to the security and resilience of the bitcoin ecosystem. The following article explains some reasons to run your own bitcoin node:

What’s Umbrel?

Umbrel is a beautiful personal server OS for self-hosting. You can run a personal server in your home, self-host open source apps like Nextcloud and Bitcoin node, break away from big tech, and take full control of your data for free. Umbrel can be installed on a Raspberry Pi 4 or any Ubuntu/Debian system.

Assembling the node is pretty easy. You just need to:

  • Put the Raspberry in its case
  • Put the storage drive in its enclosure
  • Connect the storage drive into any of the two USB 3.0 ports (blue colored) on the Raspberry Pi
  • Connect the Raspberry to your router using the ethernet cable

Step 9. Wait until Umbrel is accesible

After 5 minutes, your Umbrel will be accessible at http://umbrel.local on any device that’s connected to the same network as the Raspberry Pi. If you can’t access your Umbrel, you can use Angry IP Scanner to find the IP address of your Umbrel and type that in the browser instead of umbrel.local. If you’re using Windows, try accessing http://umbrel in the browser. And if you’re using a VPN, try turning it off.
