Running Local Network

This section is focused on guiding users through the process of setting up and running a local network, with clear steps and additional context to ensure a smooth setup experience.

Setting Up a Local Network with Niskala

This guide provides detailed instructions for setting up and running a local network using Niskala, built with Substrate. This setup is ideal for development, testing, and experimentation with Niskala.

Prerequisites

Before you begin, ensure you have the following:

  • A compatible operating system (Linux, macOS, or Windows).
  • Rust installed on your system.
  • Familiarity with command-line operations.
  • Zombienet installed for local testnet setup.
  • Get the Latest Binary, visit the Release page of the Mandala Github repository.

Installation

Step 1: Install Dependencies

Ensure your system has the necessary dependencies. Follow the Substrate Installation Guide for your specific platform to install required packages.

Step 2: Clone the Repository

Clone the Mandala Node repository to your local machine:

git clone https://github.com/your-repo/mandala-node.git
cd mandala-node

Step 3: Build the Node

Compile the node with the desired runtime:

cargo build --release --features mandala-native

Note: Use niskala-native if you prefer the Niskala runtime.

Running a Local Network

Step 1: Generate Genesis State and Runtime

Generate the genesis state and runtime for your node:

./target/release/mandala export-genesis-state --dev > <path>
./target/release/mandala export-genesis-wasm --dev > <path>

Replace the path with folder you wish to store the state and runtime

Step 2: Set Up the Relay Chain

Navigate to your Zombienet directory and start the relay chain:

cd zombienet
./run.sh <zombienet-path>

Info: This command initializes a 2-node relay chain with Bob and Alice as validators.

Step 3: Launch the Collator

Return to the Mandala Node directory and start the collator:

./target/release/mandala --dev --charlie --collator --rpc-port 9944 --port 30333 -- --chain ./zombienet/plain.json --discover-local --port 30334

Step 4: Register the Parachain

After starting the Zombienet script, register your parachain:

  1. Open a browser and navigate to the Polkadot/Substrate Portal.
  2. In the developer tab, go to "sudo" and select parasSudoWrapper.
  3. Choose sudoScheduleParaInitialize(id, genesis).
  4. Set the id parameter to 2000.
  5. Upload the genesis-state file for the genesisHead parameter.
  6. Set paraKind to true and submit the transaction.

Wait for the next epoch to start, and your parachain should begin producing blocks.

Interacting with the Local Network

You can interact with your local network using the Polkadot/Substrate Portal. This interface allows you to explore blocks, transactions, and other network activities.
