# 🖥️ Node Operators

Node operators run and maintain XChain nodes that support execution, security, and availability across the network. As XChain operates autonomously on the Layer-2 Parallel Subnetwork (L2PS) framework, reliable node performance is essential to ensure correct execution and verifiable attestations within the broader DEMOS ecosystem.

Anyone may operate an XChain node, provided they meet the required system, storage, and network performance standards.

#### Requirements

| Component             | Requirement                                                 |
| --------------------- | ----------------------------------------------------------- |
| **Operating System**  | 64-bit Linux (Debian-based preferred), Kernel 4.4 or higher |
| **Architecture**      | x86 preferred                                               |
| **CPU**               | 4 cores / 4 threads, 64-bit modern CPU                      |
|                       | x86: 2015 or newer                                          |
|                       | ARM: 2018 or newer                                          |
| **Memory (RAM)**      | 16 GB DDR4 or higher                                        |
| **Storage**           | SSD with ≥ 500 MB/s average random read/write               |
|                       | Minimum 250 GB available disk space                         |
| **Network Bandwidth** | 1 Gbps recommended                                          |
|                       | Sustained low performance may result in removal             |

XChain nodes may be deployed on a Virtual Private Server (VPS). When using a VPS, operators must provision **at least double the above requirements**, **except for RAM and disk space**, to account for shared resource overhead.
