# Substrate Node Template | ||
# Metaquity Network PoA Node | ||
|
||
A fresh [Substrate](https://substrate.io/) node, ready for hacking :rocket: | ||
|
||
A standalone version of this template is available for each release of Polkadot in the [Substrate Developer Hub Parachain Template](https://github.com/substrate-developer-hub/substrate-parachain-template/) repository. | ||
The parachain template is generated directly at each Polkadot release branch from the [Node Template in Substrate](https://github.com/paritytech/substrate/tree/master/bin/node-template) upstream | ||
|
||
It is usually best to use the stand-alone version to start a new project. | ||
All bugs, suggestions, and feature requests should be made upstream in the [Substrate](https://github.com/paritytech/substrate/tree/master/bin/node-template) repository. | ||
|
||
## Getting Started | ||
|
||
Depending on your operating system and Rust version, there might be additional packages required to compile this template. | ||
Check the [Install](https://docs.substrate.io/install/) instructions for your platform for the most common dependencies. | ||
Alternatively, you can use one of the [alternative installation](#alternatives-installations) options. | ||
|
||
Setup pre-commit hook to check code with [rustfmt](https://github.com/rust-lang/rustfmt) before committing it. | ||
|
||
```sh | ||
ln -sf $PWD/scripts/pre-commit.sh $PWD/.git/hooks/pre-commit | ||
``` | ||
|
||
### Build | ||
|
||
Use the following command to build the node without launching it: | ||
|
||
```sh | ||
cargo build --release | ||
``` | ||
|
||
### Embedded Docs | ||
|
||
After you build the project, you can use the following command to explore its parameters and subcommands: | ||
|
||
```sh | ||
./target/release/node-template -h | ||
``` | ||
|
||
You can generate and view the [Rust Docs](https://doc.rust-lang.org/cargo/commands/cargo-doc.html) for this template with this command: | ||
|
||
```sh | ||
cargo +nightly doc --open | ||
``` | ||
|
||
### Single-Node Development Chain | ||
|
||
The following command starts a single-node development chain that doesn't persist state: | ||
|
||
```sh | ||
./target/release/node-template --dev | ||
``` | ||
|
||
To purge the development chain's state, run the following command: | ||
|
||
```sh | ||
./target/release/node-template purge-chain --dev | ||
``` | ||
|
||
To start the development chain with detailed logging, run the following command: | ||
|
||
```sh | ||
RUST_BACKTRACE=1 ./target/release/node-template -ldebug --dev | ||
``` | ||
|
||
Development chains: | ||
|
||
- Maintain state in a `tmp` folder while the node is running. | ||
- Use the **Alice** and **Bob** accounts as default validator authorities. | ||
- Use the **Alice** account as the default `sudo` account. | ||
- Are preconfigured with a genesis state (`/node/src/chain_spec.rs`) that includes several prefunded development accounts. | ||
|
||
|
||
To persist chain state between runs, specify a base path by running a command similar to the following: | ||
|
||
```sh | ||
// Create a folder to use as the db base path | ||
$ mkdir my-chain-state | ||
|
||
// Use of that folder to store the chain state | ||
$ ./target/release/node-template --dev --base-path ./my-chain-state/ | ||
|
||
// Check the folder structure created inside the base path after running the chain | ||
$ ls ./my-chain-state | ||
chains | ||
$ ls ./my-chain-state/chains/ | ||
dev | ||
$ ls ./my-chain-state/chains/dev | ||
db keystore network | ||
``` | ||
|
||
### Connect with Polkadot-JS Apps Front-End | ||
|
||
After you start the node template locally, you can interact with it using the hosted version of the [Polkadot/Substrate Portal](https://polkadot.js.org/apps/#/explorer?rpc=ws://localhost:9944) front-end by connecting to the local node endpoint. | ||
A hosted version is also available on [IPFS (redirect) here](https://dotapps.io/) or [IPNS (direct) here](ipns://dotapps.io/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/explorer). | ||
You can also find the source code and instructions for hosting your own instance on the [polkadot-js/apps](https://github.com/polkadot-js/apps) repository. | ||
|
||
### Multi-Node Local Testnet | ||
|
||
If you want to see the multi-node consensus algorithm in action, see [Simulate a network](https://docs.substrate.io/tutorials/get-started/simulate-network/). | ||
|
||
## Template Structure | ||
|
||
A Substrate project such as this consists of a number of components that are spread across a few directories. | ||
|
||
### Node | ||
|
||
A blockchain node is an application that allows users to participate in a blockchain network. | ||
Substrate-based blockchain nodes expose a number of capabilities: | ||
|
||
- Networking: Substrate nodes use the [`libp2p`](https://libp2p.io/) networking stack to allow the | ||
nodes in the network to communicate with one another. | ||
- Consensus: Blockchains must have a way to come to [consensus](https://docs.substrate.io/fundamentals/consensus/) on the state of the network. | ||
Substrate makes it possible to supply custom consensus engines and also ships with several consensus mechanisms that have been built on top of [Web3 Foundation research](https://research.web3.foundation/en/latest/polkadot/NPoS/index.html). | ||
- RPC Server: A remote procedure call (RPC) server is used to interact with Substrate nodes. | ||
|
||
There are several files in the `node` directory. | ||
Take special note of the following: | ||
|
||
- [`chain_spec.rs`](./node/src/chain_spec.rs): A [chain specification](https://docs.substrate.io/build/chain-spec/) is a source code file that defines a Substrate chain's initial (genesis) state. | ||
Chain specifications are useful for development and testing, and critical when architecting the launch of a production chain. | ||
Take note of the `development_config` and `testnet_genesis` functions,. | ||
These functions are used to define the genesis state for the local development chain configuration. | ||
These functions identify some [well-known accounts](https://docs.substrate.io/reference/command-line-tools/subkey/) and use them to configure the blockchain's initial state. | ||
- [`service.rs`](./node/src/service.rs): This file defines the node implementation. | ||
Take note of the libraries that this file imports and the names of the functions it invokes. | ||
In particular, there are references to consensus-related topics, such as the [block finalization and forks](https://docs.substrate.io/fundamentals/consensus/#finalization-and-forks) and other [consensus mechanisms](https://docs.substrate.io/fundamentals/consensus/#default-consensus-models) such as Aura for block authoring and GRANDPA for finality. | ||
|
||
|
||
|
||
### Runtime | ||
|
||
In Substrate, the terms "runtime" and "state transition function" are analogous. | ||
Both terms refer to the core logic of the blockchain that is responsible for validating blocks and executing the state changes they define. | ||
The Substrate project in this repository uses [FRAME](https://docs.substrate.io/fundamentals/runtime-development/#frame) to construct a blockchain runtime. | ||
FRAME allows runtime developers to declare domain-specific logic in modules called "pallets". | ||
At the heart of FRAME is a helpful [macro language](https://docs.substrate.io/reference/frame-macros/) that makes it easy to create pallets and flexibly compose them to create blockchains that can address [a variety of needs](https://substrate.io/ecosystem/projects/). | ||
|
||
Review the [FRAME runtime implementation](./runtime/src/lib.rs) included in this template and note the following: | ||
|
||
- This file configures several pallets to include in the runtime. | ||
Each pallet configuration is defined by a code block that begins with `impl $PALLET_NAME::Config for Runtime`. | ||
- The pallets are composed into a single runtime by way of the [`construct_runtime!`](https://crates.parity.io/frame_support/macro.construct_runtime.html) macro, which is part of the core FRAME Support [system](https://docs.substrate.io/reference/frame-pallets/#system-pallets) library. | ||
|
||
### Pallets | ||
|
||
The runtime in this project is constructed using many FRAME pallets that ship with the [core Substrate repository](https://github.com/paritytech/substrate/tree/master/frame) and a template pallet that is [defined in the `pallets`](./pallets/template/src/lib.rs) directory. | ||
|
||
A FRAME pallet is compromised of a number of blockchain primitives: | ||
|
||
- Storage: FRAME defines a rich set of powerful [storage abstractions](https://docs.substrate.io/build/runtime-storage/) that makes it easy to use Substrate's efficient key-value database to manage the evolving state of a blockchain. | ||
- Dispatchables: FRAME pallets define special types of functions that can be invoked (dispatched) from outside of the runtime in order to update its state. | ||
- Events: Substrate uses [events and errors](https://docs.substrate.io/build/events-and-errors/) to notify users of important changes in the runtime. | ||
- Errors: When a dispatchable fails, it returns an error. | ||
- Config: The `Config` configuration interface is used to define the types and parameters upon which a FRAME pallet depends. | ||
|
||
## Alternatives Installations | ||
|
||
Instead of installing dependencies and building this source directly, consider the following alternatives. | ||
|
||
### Docker | ||
|
||
Please follow the [Substrate Docker instructions here](https://github.com/paritytech/substrate/blob/master/docker/README.md) to build the Docker container with the Substrate Node Template binary. | ||
