Shardeum Validator CLI

Overview

The Shardeum Validator CLI is a command-line interface tool designed for managing nodes on the Shardeum network. It provides essential functionality for node management and collects debug data from running the network, making it an imporant part of the Shardeum network toolkit.

Prerequisites

Before diving into the Validator CLI, ensure you have the following:

• Node.js (v.18.16.1 recommended)
• npm (usually comes with Node.js)
• Git

Installation and Setup

1. Clone the Repository

git clone [email protected]:shardeum/validator-cli.git
cd validator-cli

2. Set Up Symlink (Local Network Only)

When running a local network, the Validator CLI requires a symlink to the locally running Shardeum repository. Create the symlink by running this command in the cli directory:

ln -s /path/to/shardeum/repo ../validator
ls ../validator  # Verify the symlink

Replace /path/to/shardeum/repo with the actual path to your local Shardeum repository.

3. Install Dependencies

Install the necessary dependencies and link the CLI to the local network:

npm ci && npm link

Configuration

Local Network Configuration

For a local network setup, update the configuration in the src/config/default-network-config.ts file :

export const defaultNetworkConfig = {
  server: {
    baseDir: '.',
    p2p: {
      existingArchivers: [
        {
          ip: '127.0.0.1',
          port: 4000,
          publicKey: '758b1c119412298802cd28dbfa394cdfeecc4074492d60844cc192d632d84de3',
        },
      ],
    },
    ip: {
      externalIp: '127.0.0.1',
      externalPort: 9050,
      internalIp: '127.0.0.1',
      internalPort: 10045,
    },
    reporting: {
      report: true,
      recipient: 'http://localhost:3000/api',
      interval: 2,
      console: false,
    },
  },
};

Live Network Configuration

For connecting to a live network, update the defaultNetworkConfig object with the details of live archivers. For example:

export const defaultNetworkConfig = {
  server: {
    // ... other settings remain the same
    p2p: {
      existingArchivers: [
        {
          ip: '198.58.110.213',
          port: 4000,
          publicKey: 'd34b80a5a6f9638b7c75d6eb6e59d35d9a3e103f1877827eebbe973b8281f794',
        },
        // Add more live archivers as needed
      ],
    },
    // ... rest of the configuration remain the same
  },
};

Remember to replace the example IP, port, and public key with actual values for the version of the network you're connecting to.

After making changes, recompile the CLI:

npm run compile
