Original：🇺🇸 English

Not Translated

Runs a Base node for production environments. Covers hardware requirements, Reth client setup, networking, and sync troubleshooting. Use when setting up self-hosted RPC infrastructure or running archive nodes. Covers phrases like "run a Base node", "set up Base RPC", "Base node hardware requirements", "Reth Base setup", "sync Base node", "self-host Base", or "run my own node".

Running a Base Node

For production apps requiring reliable, unlimited RPC access.

Security

Restrict RPC access — bind to
```
127.0.0.1
```
or a private interface, never expose RPC ports (
```
8545
```
/
```
8546
```
) to the public internet without authentication
Firewall rules — only open ports 9222 (Discovery v5) and 30303 (P2P) to the public; block all other inbound traffic
Run as a non-root user with minimal filesystem permissions
Use TLS termination (reverse proxy with nginx/caddy) if exposing the RPC endpoint to remote clients
Monitor for unauthorized access — log and alert on unexpected RPC calls or connection spikes

Hardware Requirements

CPU: 8-Core minimum
RAM: 16 GB minimum

Storage: NVMe SSD, formula:

(2 × chain_size) + snapshot_size + 20% buffer

Networking

Required Ports:

Port 9222: Critical for Reth Discovery v5
Port 30303: P2P Discovery & RLPx

If these ports are blocked, the node will have difficulty finding peers and syncing.

Client Selection

Use Reth for Base nodes. Geth Archive Nodes are no longer supported.

Reth provides:

Better performance for high-throughput L2
Built-in archive node support

Syncing

Initial sync takes days
Consumes significant RPC quota if using external providers
Use snapshots to accelerate (check Base docs for URLs)

Sync Status

Incomplete sync indicator:

Error: nonce has already been used

when deploying.

Verify sync:

Compare latest block with explorer
Check peer connections
Monitor logs for progress
