Component	Minimum Requirements	Recommended Requirements
OS	Ubuntu 18.04 or newer	Ubuntu 20.04 or newer
Processor	2 cores	4 cores
Memory	4 GB	8 GB
Disk	50 GB SSD	100 GB SSD

Prerequisites

Ensure that you have the following components installed:

• Nim: The programming language used for Nwaku.

• C Compiler, GNU Make, Bash, and Git: Essential tools for building the node.

Installation Steps

1. Clone the Nwaku Repository:

   git clone https://github.com/waku-org/nwaku.git
   cd nwaku

2. Build the Node:

   • First, update all Git submodules:

     make update

   • Then, build the node:

     make wakunode2

3. Run the Node:

   • Start the node using DNS discovery:

     ./build/wakunode2 --dns-discovery --dns-discovery-url=DNS_BOOTSTRAP_NODE_URL

   • To see available command-line options, use:

     ./build/wakunode2 --help

Configuration Options

Parameter	Description
Static Peers	Configure bootstrap nodes for initial connections.
DNS Discovery	Enable DNS-based peer discovery.
Discv5	Use the Discv5 mechanism for peer discovery.
Peer Exchange	Allow light nodes to request peers from your node.

Running in Docker

For simplicity, it is recommended to run the node using Docker Compose:

1. Create a docker-compose.yml file with the necessary configuration.

2. Start the node:

   docker-compose up -d

Monitoring and Interaction

You can interact with the running node via the REST API. For example, to get information about the node, use:

curl --location 'http://127.0.0.1:8545/debug/v1/info' --header 'Accept: application/json'
