Setting up a Nym Mixnode is a crucial step in contributing to the Nym network and enhancing its privacy features. This comprehensive guide provides step-by-step instructions for a successful mixnode setup. By following these detailed steps, you can establish your mixnode and start contributing to the Nym network.

Step 1: Prerequisites

Before you begin, ensure you have the following:

  1. VPS (Virtual Private Server): You’ll need a VPS with a public IP address and root access. Popular VPS providers include DigitalOcean, Linode, and others.
  2. Basic Command Line Knowledge: Familiarity with the command line interface (CLI) is necessary to execute commands on your VPS.\

Step 2: Connecting to your VPS

Using SSH to Connect:

  1. Open your preferred terminal on your local machine.
  2. Use SSH to connect to your VPS. Replace your_vps_ip with the actual IP address of your VPS.
ssh root@your_vps_ip

Handling SSH key passphrase or password prompts:

You might be prompted to enter your SSH key passphrase or password. Provide the necessary information to establish the SSH connection.

Step 3: Installing docker and docker compose

Updating Package List:

Update the package list on your VPS.

apt update

Docker Installation:

  1. Install docker and docker compose.
apt install docker.io docker-compose

2. Start and enable the Docker service.

systemctl start docker
systemctl enable docker

Step 4: Obtaining the Nym Mixnode docker compose file

Creating a new directory:

On your VPS, create a new directory for your Nym Mixnode.

mkdir nym-mixnode
cd nym-mixnode

Downloading the docker compose file:

Download the Nym Mixnode Docker Compose file.

wget https://github.com/nymtech/nym/releases/latest/download/nym-mixnode-docker-compose.yml

Step 5: Customizing the Configuration

Opening the docker compose file:

Open the docker compose file using a text editor of your choice.

nano nym-mixnode-docker-compose.yml

Configuring environment variables:

Customize the environment variables as needed, including the validator wallet, mix host, and other configurations.

Step 6: Starting the Mixnode

Launching the Mixnode service:

Start the Nym Mixnode by running the docker compose command.

docker-compose -f nym-mixnode-docker-compose.yml up -d

This command will start the Mixnode as a detached service.

Step 7: Monitoring your Mixnode

Using the Nym Network Explorer:

You can monitor your Mixnode status and performance using the Nym Network explorer. Visit the Mainnet or Sandbox Testnet explorer and enter your identity key.

Checking node status and performance:

Monitor the number of packets mixed and other relevant metrics to assess your node’s performance.

Step 8: Troubleshooting

Resources for issue resolution:

In case you encounter any issues or errors during the setup process, refer to the Nym documentation and community forums for assistance.

Community Support:

Don’t hesitate to seek help and guidance from the Nym community. Join relevant online forums and chat groups for additional support.

Conclusion

Congratulations! You’ve successfully set up your Nym Mixnode. Your contribution to the Nym network will help enhance privacy and security for users around the world.
