Hardware Requirements

Hard Drive

• You need to run an execution client as well as your consensus client.

• Since the Merge, third-party providers (such as Infura and Alchemy) are no longer viable options to outsource execution layer responsibilities. All stakers must run both an execution and a consensus client to properly attest to the network.

• As of May 2022, you'll need ~1TB for the Mainnet execution chain data alone (growing at >1GB/day).

• Ethereum had its genesis on July 30, 2015. It is growing in size over time, and the introduction of Danksharding will also increase storage, memory, and bandwidth requirements.

• You'll need SSD storage to consistently handle necessary read/write speeds.

• Be sure to account for enough space on your drive until you run maintenance on your node.

Recommendation disclaimer

Hardware suggestions are an ever-evolving target. Current minimum requirements are likely to increase by an order of magnitude after the introduction of Danksharding. Do your own research before depositing funds.

CPU and RAM

• Check with client documentation to ensure the hardware you want to use is sufficient and supported.

• Resource usage can vary significantly between clients. Research the different clients if you're working with resource constraints.
