I set it up two years ago. The Pi 4 handles the blockchain sync, the p2p connections, and the wallet RPC. It draws 5 watts. That’s decentralisation you can hold in your hand. I’ve watched other networks require enterprise hardware. Monero kept the entry bar low. That matters for censorship resistance. If running a node is cheap, the network is harder to kill. Satoshi’s original vision included that accessible infrastructure. If you’re curious about how to set up your own node, this guide is the most practical I’ve seen.
