Sepolia is Ethereum’s primary testnet for application developers, paired with the Beacon Chain for Ethereum 2.0 consensus.
This guide covers two deployment methods for running a Sepolia Beacon Chain node:
- Systemd Method - Simple, direct system access
- Docker Method - Containerized deployment
1. Prerequisites
Before starting, ensure you have:
- Operating System: Ubuntu/Debian system
- Storage: 1TB SSD (NVMe preferred)
- RAM: 16GB+ (varies by method)
- Knowledge: Basic Linux administration
- Domain: Required for the Docker method only

2. Deployment Methods Comparison
a. Method 1: Systemd + UFW
Pros:
- Simpler setup process
- Direct system access
- No container overhead
- Straightforward troubleshooting
Cons:
- Higher memory usage (can exceed 16GB cache)
- Manual updates required
- No SSL automation
- Basic external access
b. Method 2: Docker + Nginx + Certbot
Pros:
- Better resource control (~26GB managed)
- Easy deployment and updates
- Automated SSL certificates
- External access through your own domain
- Simplified updates with
docker compose pull
Cons:
- More complex architecture
- Steeper learning curve
- Container management overhead
c. Resource Usage Summary
| Method | Memory Management | Setup Complexity | External Access | Updates |
|---|---|---|---|---|
| Systemd | Can exceed 16GB | Simple | Basic | Manual |
| Docker | ~26GB managed | Complex | Professional | Automated |
3. Choose Your Method
