1. Overview of Nexi Chain

• Chain Type: Delegated Proof of Stake (DPoS)

Nexi chain operates on a Delegated Proof of Stake (DPoS) mechanism, where validators are elected to produce and validate blocks. Validators need to hold a minimum amount of Polygon’s native tokens (POL) to participate in the network as a validator.

Software Requirements:

• Operating System: Linux-based OS (e.g., Ubuntu 20.04 or later)
• Dependencies: Docker, Git, and other dependencies as specified by Nexi’s documentation

Validator Software:

• Client Software: Obtain the Nexi node software from Nexi’s official website or a trusted source.
• Configuration: Configuration files will need to be set up, including network parameters and validator settings.

Token Requirements:

• Polygon Tokens (POL): Validators must hold a specified minimum amount of POL tokens.
  
  

3. Setting Up a Validator Node

Step 1: Prepare Your Environment

1. Update Your OS:
   • Ensure your Linux system is up-to-date: sudo apt update && sudo apt upgrade
2. Install Dependencies:
   • Install Docker: sudo apt install docker.io
   • Install Git: sudo apt install git

Step 2: Obtain Nexi Node Software

1. Download Nexi Node Software:
   • Visit the official Nexi website or contact Nexi’s support team to download the latest version of the Nexi node software.
2. Install the Software:
   • Follow the installation instructions provided with the software. This usually involves extracting the downloaded files and running installation scripts.

Step 3: Configure Your Node

1. Edit Configuration Files:
   • Modify the configuration files to set up your validator node. This will include details such as your node’s identity, voting keys, and network connection settings.
2. Initialize the Node:
   • Run initialization commands as per the documentation provided with the software to set up your node for first-time use.

Step 4: Register as a Validator

1. Obtain POL Tokens:
   • Acquire the required amount of POL tokens from exchanges or other sources.
2. Create a Validator Account:
   • Use the tools or interfaces provided by Nexi to create a validator account. Ensure your account is funded with the necessary POL tokens.
3. Submit Validator Registration:
   • Follow Nexi’s process for registering as a validator. This typically involves broadcasting a transaction to register your node on the network.
4. Stake POL Tokens:
   • Delegate or stake the required amount of POL tokens to activate and operate your validator node.
     
     

4. Running and Monitoring Your Node

Start Your Node:

• Use the command provided in the Nexi node software documentation to start your validator node. This might involve using Docker commands or specific scripts.

Monitor Node Performance:

• Regularly check your node’s logs and performance metrics. Utilize any available monitoring tools or dashboards.

Maintain Node Security:

• Ensure your node’s security by keeping software updated, managing access controls, and implementing firewalls and intrusion detection systems.

Participate in Governance:

Engage in network governance by participating in votes and proposals. Contribute to the decision-making process and ensure network stability.
