Hardware requirements

• RAM: 2GB. ECC memory is better. Additionally, it's recommended to use DDR4 memory with targeted row refresh (TRR) enabled (https://rambleed.com/).
• Disk space: 500 GB (400GB for Bitcoin blockchain + some room) for an unpruned instance of Bitcoin Core.
  • This can be significantly lowered by enabling pruning. Note: Pruning is not supported by electrs and fulcrum.

Tested low-end hardware includes:

• Raspberry Pi 4
• PC Engines apu2c4
• Gigabyte GB-BACE-3150
• Gigabyte GB-BACE-3160

Some hardware (including Intel NUCs) may not be compatible with the hardened kernel preset (See https://github.com/fort-nix/nix-bitcoin/issues/39#issuecomment-517366093 for a workaround).
