# XChain Nodes: What They Are and How to Use Them

Being an independent chain operating on the L2PS protocol, XChain relies on nodes to grant security, integrity and reproducibility. 

A typical XChain node is both of the following:

* A DEMOS Network compliant and participating node
* An XChain L2PS compliant and participating node 

The design principle behind this ubiquity is that, while remaining standalone, XChain benefits from the protection of the whole DEMOS Network in terms of consensus and reliability. 

Consequently, anyone can own and run an XChain node, provided they comply with the hardware and security requirements.
