Getting Started

Follow these steps to get started with the Node

Rust Setup

First, complete the basic Rust setup instructions.

Single-Node Development Chain

This command will start the single-node development chain with persistent state:

./target/debug/myriad \
--base-path .local \
--dev \
--alice \
--collator \
--force-authoring \
-- \
--execution wasm \
--dev

Purge the development chain's state:

./target/debug/myriad \
purge-chain \
--base-path .local \
--dev

Start the development chain with detailed logging:

RUST_LOG=debug RUST_BACKTRACE=1 ./target/debug/myriad \
./target/debug/myriad \
--base-path .local \
--dev \
--alice \
--collator \
--force-authoring \
-lruntime=debug \
-- \
--execution wasm \
--dev

Run in Docker

First, install Docker and Docker Compose.

Then run the following command to start a single node development chain.

./.maintain/docker/create-network.sh

./.maintain/docker/start-docker-compose.sh

Migrating Octopus Appchain to Rococo Parachain

1. Fork the Substrate Cumulus Node Parachain Template Repository

Step 1: Begin by forking a new repository based on the Substrate Cumulus Node Parachain Template.

• Action Required: Click the "Fork" button on the GitHub repository page to create a copy under your account.

---

2. Define Chain Specification Configuration

Step 2: In order to configure your Substrate project, you need to define the Chain Specification Configuration. This configuration encompasses essential details about your blockchain. These details include:

• ID: A unique identifier for your blockchain.
• Name: The name of your blockchain.
• Chain Type: The type of blockchain (e.g., Parachain, Relay Chain).
• Chain Genesis: Information about the initial state of your blockchain, including privileged accounts, collator accounts, pre-funded accounts, and the parachain ID.
• Bootnodes: Addresses of nodes that can be used as entry points into your blockchain.
• Telemetry: Telemetry server details, if applicable.
• Protocol ID: The identifier for the network protocol.
• Fork ID: ID for specifying forks in the blockchain.
• Properties: Miscellaneous properties or settings.
• Extension: Any additional extensions or customizations.

It's important to configure the Chain Specification for the following contexts:

• Local Chain: Configuration for a local development environment.
• Development Chain: Configuration for a development environment.
• Rococo Chain: Configuration for integration with the Rococo testnet.

---

3. Replace Parachain Template Runtime

Step 3: Replace the default runtime of the Substrate Cumulus Node Parachain Template, which is known as parachain_template_runtime, with the runtime of the Octopus application that you intend to migrate to the parachain.

• Action Required: Replace the runtime code files as needed to integrate the Octopus application runtime.

---

4. Move Octopus Application Pallets

Step 4: Move the Octopus application's pallet code into the new parachain repository. Ensure that all pallets are placed within the pallets folder of the repository.

• Action Required: Organize the Octopus application's pallet code files within the pallets directory of your new repository.

Guide to Testing the Project Using Docker

Substrate is a modular framework that enables you to create purpose-built blockchains by composing custom or pre-built components. This guide will walk you through the steps to use Docker for testing a Rust-based Substrate project.

Prerequisites

1. Docker Installed: Ensure Docker is installed on your machine. If not, follow the official installation guide.

2. Docker Daemon Running: Ensure the Docker daemon is running.

3. Substrate Project: A directory containing your Substrate project.

Step-by-Step Instructions

1. Create a Dockerfile

Create a Dockerfile in the root directory of your Substrate project with the following content:

# Use an official Rust base image
FROM rust:1.70.0

# Set the working directory inside the container
WORKDIR /usr/src/substrate_project

# Copy the entire project into the container
COPY . .

# Build the application
RUN cargo build

# Run tests on container startup
CMD ["cargo", "test"]

2. Build the Docker Image

Navigate to your project's directory and build the Docker image:

cd /path/to/your/myriad-node-parachain
docker build -t substrate-test .

---

These steps provide a comprehensive guide for migrating Substrate project from an Octopus Appchain to a Rococo Parachain. Ensure that you follow each step carefully to successfully configure your Substrate-based parachain with the Octopus application runtime.
