Running a Base Node
For production apps requiring reliable, unlimited RPC access.
Security
- Restrict RPC access — bind to
127.0.0.1or 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
