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

Relay Specification Minimum Recommended
CPUs 2 4
RAM 4GB 8GB
HDD 80GB 100GB - 120GB

Supported OS Release Version(s)
Ubuntu 18.x / 20.x

Ubuntu 16.x and older is no longer supported.


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.
