Hardware

The physical machines: miners, node boxes, signing devices.

• ASIC miners

  The industrial machine that mines Bitcoin: specialized chips, huge fans, serious power draw.

• Node hardware

  What it actually takes to run your own node: less than you think.

• Signing devices

  A small offline gadget that holds your keys and signs transactions without exposing them.

• Open-source hardware

  Hardware whose designs are published, so you can inspect what touches your keys.

• DIY vs pre-built

  Build your node or signing setup yourself, or buy it ready-made. Both count.
