Run a HPP Node

Minimum hardware configuration

The following is the minimum hardware configuration required to set up a Nitro full node (not archival):

Resource

Recommended

RAM

16 GB

CPU

4 core CPU (for AWS, a t3 xLarge instance)

Storage Type

NVMe SSD drives are recommended

Storage size

Depends on the chain and its traffic overtime

Please note that:

These minimum requirements for RAM and CPU are recommended for nodes that process a small amount of RPC requests. For nodes that require processing multiple simultaneous requests, both RAM and number of CPU cores will need to be scaled with the amount of traffic being served.
Single core performance is important. If the node is falling behind and a single core is 100% busy, it is recommended to update to a faster processor
The minimum storage requirements will change over time as the chain grows. Using more than the minimum requirements to run a robust full node is recommended.

Prerequisites

Download and install Docker, ensure it is running.

Step 1. Download chaininfo file

A chaininfo.json file is required to run the node.

Step 2. Run the node

Specify a local path to store data for running the node, determine the Arbitrum Nitro version, and then execute it. The contents of the chaininfo.json file downloaded above have been included in the docker run command.

The node should now be running and looking for peers to sync.

HPP generates blocks only when there are transactions to process. So if you don't see new blocks coming in, it just means there's no transaction activity - your node is still syncing correctly.
