hardware requirements for ethereum node

• Minimum: 4 cores with 8 threads
• Recommended: 8 cores with 16 threads

The CPU is responsible for handling the heavy computations required for processing Ethereum transactions. A faster CPU will result in a smoother and more efficient node experience.

• Minimum: 8GB
• Recommended: 16GB+

RAM stores the Ethereum blockchain data and other operating system processes. More RAM allows the node to handle larger blockchain workloads and operate faster.

• Minimum: 1TB SSD
• Recommended: 2TB SSD+

The Ethereum blockchain is constantly growing, so it's essential to have sufficient storage to accommodate it. An SSD (Solid State Drive) is highly recommended for faster read/write speeds.

• High-speed Internet connection (e.g., wired Ethernet)
• Minimum: 50Mbps upload/download speed
• Recommended: 100Mbps or more

A stable and fast network connection is crucial for syncing the blockchain data and for sending/receiving transactions efficiently.

• Linux (e.g., Ubuntu, Debian)
• macOS

Most Ethereum nodes are run on Linux-based operating systems as they offer better stability and security than other options.

• Power Supply: Ensure the power supply is sufficient to handle the hardware requirements.
• Cooling: Ethereum nodes can generate heat, so adequate cooling is essential.
• Firewall: Configure the firewall to allow incoming and outgoing connections on the required ports (30303 for P2P network, 8545 for JSON-RPC).
