Hardware Requirements
| Component | Minimum Specs | Recommended Specs |
|----------------|---------------------------|---------------------------|
| Memory | 16GB RAM | 24GB+ RAM |
| Storage | 2TB SSD | 4TB SSD |
| Processor | Quad-core CPU | Hexa-core CPU |
Why the upgrade?
- Ethereum’s blockchain growth demands more resources.
- 16GB RAM may lead to performance bottlenecks; 24GB ensures smoother operation.
- A 4TB SSD prevents frequent storage maintenance.
Installing Ubuntu Server
Download Ubuntu Server
- Get the latest LTS version here.
Create a Bootable USB
- Use tools like Rufus (Windows) or BalenaEtcher (macOS/Linux).
Installation Steps
- Select "Ubuntu Server" during boot.
- Partition disks: Allocate at least 100GB for the OS, leaving the rest for blockchain data.
- Set up a strong password and enable SSH for remote management.

2. How long does syncing the Ethereum blockchain take?
With a fast SSD, expect 5–7 days for initial sync.
3. Is Ubuntu Server better than Desktop for staking?
Yes. The server version has lower overhead and better stability.
