| # Substrate Cumulus Parachain Template | ||
| <div align="center"> | ||
|
|
||
| A new [Cumulus](https://github.com/paritytech/polkadot-sdk/tree/master/cumulus)-based Substrate node, ready for hacking ☁️.. | ||
| # Polkadot SDK's Parachain Template | ||
|
|
||
| This project is originally a fork of the | ||
| [Substrate Node Template](https://github.com/substrate-developer-hub/substrate-node-template) | ||
| modified to include dependencies required for registering this node as a **parathread** or | ||
| **parachain** to a **relay chain**. | ||

|
|
||
| The stand-alone version of this template is hosted on the | ||
| [Substrate Devhub Parachain Template](https://github.com/substrate-developer-hub/substrate-parachain-template/) | ||
| for each release of Polkadot. It is generated directly to the upstream | ||
| [Parachain Template in Cumulus](https://github.com/paritytech/polkadot-sdk/tree/master/cumulus/parachain-template) | ||
| at each release branch using the | ||
| [Substrate Template Generator](https://github.com/paritytech/substrate-template-generator/). | ||
| > This is a template for creating a [parachain](https://wiki.polkadot.network/docs/learn-parachains) based on Polkadot SDK. | ||
| > | ||
| > This template is automatically updated after releases in the main [Polkadot SDK monorepo](https://github.com/paritytech/polkadot-sdk). | ||

| parathreads [here](https://wiki.polkadot.network/docs/learn-parathreads). | ||
| </div> | ||
|
|
||
| * ⏫ This template provides a starting point to build a [parachain](https://wiki.polkadot.network/docs/learn-parachains). | ||
|
|
||
| 🧙 Learn about how to use this template and run your own parachain testnet for it in the | ||
| [Devhub Cumulus Tutorial](https://docs.substrate.io/tutorials/v3/cumulus/start-relay/). | ||
| * ☁️ It is based on the | ||
| [Cumulus](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/polkadot_sdk/cumulus/index.html) framework. | ||
|
|
||
| * 🔧 Its runtime is configured of a single custom pallet as a starting point, and a handful of ready-made pallets | ||
| such as a [Balances pallet](https://paritytech.github.io/polkadot-sdk/master/pallet_balances/index.html). | ||
|
|
||
| * 👉 Learn more about parachains [here](https://wiki.polkadot.network/docs/learn-parachains) | ||
|
|
||
| ## Template Structure | ||
|
|
||
| A Polkadot SDK based project such as this one consists of: | ||
|
|
||
| * 💿 a [Node](./node/README.md) - the binary application. | ||
| * 🧮 the [Runtime](./runtime/README.md) - the core logic of the parachain. | ||
| * 🎨 the [Pallets](./pallets/README.md) - from which the runtime is constructed. | ||
|
|
||
| ## Getting Started | ||
|
|
||
| * 🦀 The template is using the Rust language. | ||
|
|
||
| * 👉 Check the | ||
| [Rust installation instructions](https://www.rust-lang.org/tools/install) for your system. | ||
|
|
||
| * 🛠️ Depending on your operating system and Rust version, there might be additional | ||
| packages required to compile this template - please take note of the Rust compiler output. | ||
|
|
||
| ### Build | ||
|
|
||
| 🔨 Use the following command to build the node without launching it: | ||
|
|
||
| ```sh | ||
| cargo build --release | ||
| ``` | ||
|
|
||
| 🐳 Alternatively, build the docker image: | ||
|
|
||
| ```sh | ||
| docker build . -t polkadot-sdk-parachain-template | ||
| ``` | ||
|
|
||
| ### Local Development Chain | ||
|
|
||
| 🧟 This project uses [Zombienet](https://github.com/paritytech/zombienet) to orchestrate the relaychain and parachain nodes. | ||
| You can grab a [released binary](https://github.com/paritytech/zombienet/releases/latest) or use an [npm version](https://www.npmjs.com/package/@zombienet/cli). | ||
|
|
||
| This template produces a parachain node. | ||
| You still need a relaychain node - you can download the `polkadot` | ||
| (and the accompanying `polkadot-prepare-worker` and `polkadot-execute-worker`) | ||
| binaries from [Polkadot SDK releases](https://github.com/paritytech/polkadot-sdk/releases/latest). | ||
|
|
||
| Make sure to bring the parachain node - as well as `polkadot`, `polkadot-prepare-worker`, `polkadot-execute-worker`, | ||
| and `zombienet` - into `PATH` like so: | ||
|
|
||
| ```sh | ||
| export PATH="./target/release/:$PATH" | ||
| ``` | ||
|
|
||
| This way, we can conveniently use them un the following steps. | ||
|
|
||
| 👥 The following command starts a local development chain, with a single relay chain node and a single parachain collator: | ||
|
|
||
| ```sh | ||
| zombienet --provider native spawn ./zombienet.toml | ||
|
|
||
| # Alternatively, the npm version: | ||
| npx --yes @zombienet/cli --provider native spawn ./zombienet.toml | ||
| ``` | ||
|
|
||
| Development chains: | ||
|
|
||
| * 🧹 Do not persist the state. | ||
| * 💰 Are preconfigured with a genesis state that includes several prefunded development accounts. | ||
| * 🧑⚖️ Development accounts are used as validators, collators, and `sudo` accounts. | ||
|
|
||
| ### Connect with the Polkadot-JS Apps Front-End | ||
|
|
||
| * 🌐 You can interact with your local node using the | ||
| hosted version of the Polkadot/Substrate Portal: | ||
| [relay chain](https://polkadot.js.org/apps/#/explorer?rpc=ws://localhost:9944) | ||
| and [parachain](https://polkadot.js.org/apps/#/explorer?rpc=ws://localhost:9988). | ||
|
|
||
| * 🪐 A hosted version is also | ||
| available on [IPFS](https://dotapps.io/). | ||
|
|
||
| * 🧑🔧 You can also find the source code and instructions for hosting your own instance in the | ||
| [`polkadot-js/apps`](https://github.com/polkadot-js/apps) repository. | ||
|

| # Node | ||
|
|
||
| ℹ️ A node - in Polkadot - is a binary executable, whose primary purpose is to execute the [runtime](../runtime/README.md). | ||
|
|
||
| 🔗 It communicates with other nodes in the network, and aims for | ||
| [consensus](https://wiki.polkadot.network/docs/learn-consensus) among them. | ||
|
|
||
| ⚙️ It acts as a remote procedure call (RPC) server, allowing interaction with the blockchain. | ||
|
|
||
| 👉 Learn more about the architecture, and a difference between a node and a runtime | ||
| [here](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/reference_docs/wasm_meta_protocol/index.html). | ||
|
|
||
| 👇 Here are the most important files in this node template: | ||
|
|
||
| - [`chain_spec.rs`](./src/chain_spec.rs): A chain specification is a source code file that defines the chain's | ||
| initial (genesis) state. | ||
| - [`service.rs`](./src/service.rs): This file defines the node implementation. | ||
| It's a place to configure consensus-related topics. |
