Hardware and setup paths

A node needs about a terabyte of SSD, a few gigabytes of RAM and patience. Turnkey bundles give a dashboard; Bitcoin Core on your own machine gives control.

Turnkey node bundles versus running Bitcoin Core directly.
LEVEL · Advanced
IN THIS LESSON · 2 OF 6
BY THE END YOU WILL BE ABLE TO ANSWER
  • Does a pruned node verify less than a full archival node?
  • Why verify the Bitcoin Core download's signature?
  • What does a pruned node do?
  • The chain is about 650 GB and grows 50–100 GB a year. How many years will a 1 TB SSD last at the faster rate, roughly?

Then prove it: a 3-question quiz · a challenge. The lesson marks itself complete at 100%.

After this lesson you can: pick hardware you already own or a box to buy, and choose between a turnkey bundle and Bitcoin Core directly.

Requirements

  • Storage: the blockchain is around 650 GB in 2026 and grows about 50 to 100 GB a year. A 1 TB SSD is the standard choice; 2 TB is comfortable. Spinning disks work but make the initial sync very slow.
  • Memory: 4 GB is workable, 8 GB is comfortable. More memory speeds the initial sync.
  • CPU: modest. A Raspberry Pi 4 or 5 or any mini PC is fine.
  • Internet: the initial sync downloads the whole chain once; afterwards a node uses a few GB a month, more if it serves many peers. Metered connections need limits set.

What a node needs. Modest, except the disk.

Path 1: turnkey

Buy a pre-built node or install a bundle (Umbrel, Start9, RaspiBlitz, myNode, Citadel) on a Pi or mini PC. You get a web dashboard, Bitcoin Core running underneath, and one-click apps: a block explorer, a Lightning node, an Electrum server for your wallet. The trade is trusting the bundler's packaging and update process. Good for a first node.

Path 2: Bitcoin Core directly

Download from bitcoincore.org, verify the release signature (the release notes explain how), install, run. On a desktop you get the Bitcoin-Qt GUI; on a server, bitcoind with a config file. Add an Electrum server (Fulcrum, electrs) if you want hardware-wallet software to connect. More to learn, nothing hidden.

Pruned nodes

Two columns: a turnkey bundle versus running Bitcoin Core directly.
Two paths, same node underneath.

If disk is tight, a pruned node verifies everything but keeps only recent blocks (set a target, say 20 GB). It is a full validating node with full security for you; it cannot serve old blocks to others or support some explorer and wallet features. A fine choice for a laptop.

What to avoid

Running the node on the same machine as your hot wallet seed is unwise. Exposing the RPC port to the internet is a serious risk; keep it local or behind Tor.
