#Hardware Requirements

A Relay Node is a full node in the ARK network; it maintains a complete copy of the ledger (blockchain). These nodes serve as Public API endpoint, use an internal service discovery mechanism to locate other nodes and keep each other in sync.

#Recommended Hardware Requirements

• 4GB RAM
• 40GB SSD
• 2 Cores

ARK Nodes execute many query intensive operations. The most cost-effective approach for running a high-performance node is choosing SSD over HDD. Increasing the total RAM improves cache performance.

#Configuration Requirements

• Stable internet connection

• Access to multiple open ports (actual ports may be configured)
