## Intro
- 🤏 This template is a minimal (in terms of complexity and the number of components)
template for building a blockchain node.
- 🔧 Its runtime is configured with a single custom pezpallet as a starting point, and a handful of ready-made pezpallets
such as a [Balances pezpallet](https://pezkuwichain.github.io/pezkuwi-sdk/master/pezpallet_balances/index.html).
- 👤 The template has no consensus configured - it is best for experimenting with a single node network.
## Template Structure
A Pezkuwi SDK based project such as this one consists of:
- 🧮 the [Runtime](./runtime/README.md) - the core logic of the blockchain.
- 🎨 the [Pezpallets](./pezpallets/README.md) - from which the runtime is constructed.
- 💿 a [Node](./node/README.md) - the binary application (which is not part of the cargo default-members list and is not
compiled unless building the entire workspace).
## 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.
Fetch minimal template code.
```sh
git clone https://github.com/pezkuwichain/pezkuwi-sdk-minimal-template.git minimal-template
cd minimal-template
```
## Starting a Minimal Template Chain
### Omni Node
[Omni Node](https://pezkuwichain.github.io/pezkuwi-sdk/master/pezkuwi_sdk_docs/reference_docs/omni_node/index.html) can
be used to run the minimal template's runtime. `pezkuwi-omni-node` binary crate usage is described at a high-level
[on crates.io](https://crates.io/crates/pezkuwi-omni-node).
#### Install `pezkuwi-omni-node`
Please see installation section on [crates.io/omni-node](https://crates.io/crates/pezkuwi-omni-node).
#### Build `minimal-template-runtime`
```sh
cargo build -p minimal-template-runtime --release
```
#### Install `pezstaging-chain-spec-builder`
Please see the installation section at [`crates.io/pezstaging-chain-spec-builder`](https://crates.io/crates/pezstaging-chain-spec-builder).
#### Use chain-spec-builder to generate the chain_spec.json file
```sh
chain-spec-builder create --relay-chain "dev" --para-id 1000 --runtime \
target/release/wbuild/minimal-template-runtime/minimal_template_runtime.wasm named-preset development
```
**Note**: the `relay-chain` and `para-id` flags are extra bits of information required to
configure the node for the case of representing a parachain that is connected to a relay chain.
They are not relevant to minimal template business logic, but they are mandatory information for
Omni Node, nonetheless.
#### Run Omni Node
Start Omni Node in development mode (sets up block production and finalization based on manual seal,
sealing a new block every 3 seconds), with a minimal template runtime chain spec.
```sh
pezkuwi-omni-node --chain <path/to/chain_spec.json> --dev
```
### Minimal Template Node
#### Build both node & runtime
```sh
cargo build --workspace --release
```
🐳 Alternatively, build the docker image which builds all the workspace members,
and has as entry point the node binary:
```sh
docker build . -t pezkuwi-sdk-minimal-template
```
#### Start the `minimal-template-node`
The `minimal-template-node` has dependency on the `minimal-template-runtime`. It will use
the `minimal_template_runtime::WASM_BINARY` constant (which holds the WASM blob as a byte
array) for chain spec building, while starting. This is in contrast to Omni Node which doesn't
depend on a specific runtime, but asks for the chain spec at startup.
```sh
<target/release/path/to/minimal-template-node> --tmp --consensus manual-seal-3000
# or via docker
docker run --rm pezkuwi-sdk-minimal-template
```
### Zombienet with Omni Node
#### Install `pezkuwi-zombienet`
We can install `pezkuwi-zombienet` as described [here](https://github.com/pezkuwichain/pezkuwi-zombienet-sdk/install.html#installation),
and `pezkuwi-zombienet-omni-node.toml` contains the network specification we want to start.
#### Update `pezkuwi-zombienet-omni-node.toml` with a valid chain spec path
To simplify the process of starting the minimal template with ZombieNet and Omni Node, we've included a
pre-configured development chain spec (dev_chain_spec.json) in the minimal template. The pezkuwi-zombienet-omni-node.toml
file in this template points to it, but you can update it to a new path for the chain spec generated on your machine.
To generate a chain spec refer to [pezstaging-chain-spec-builder](https://crates.io/crates/pezstaging-chain-spec-builder)
Then make the changes in the network specification like so:
```toml
# ...
chain = "dev"
chain_spec_path = "<TO BE UPDATED WITH A VALID PATH>"
default_args = ["--dev"]
# ..
```
#### Start the network
```sh
pezkuwi-zombienet --provider native spawn pezkuwi-zombienet-omni-node.toml
```
### Zombienet with `minimal-template-node`
For this one we just need to have `pezkuwi-zombienet` installed and run:
```sh
pezkuwi-zombienet --provider native spawn pezkuwi-zombienet-multi-node.toml
```
### Connect with the Pezkuwi-JS Apps Front-End
- 🌐 You can interact with your local node using the
hosted version of the [Pezkuwi/Bizinikiwi
Portal](https://pezkuwi.js.org/apps/#/explorer?rpc=ws://localhost:9944).
- 🪐 A hosted version is also
available on [IPFS](https://hezapps.io/).
- 🧑‍🔧 You can also find the source code and instructions for hosting your own instance in the
[`pezkuwi-js/apps`](https://github.com/pezkuwi-js/apps) repository.
### Takeaways
Previously minimal template's development chains:
- ❌ Started in a multi-node setup will produce forks because minimal lacks consensus.
- 🧹 Do not persist the state.
- 💰 Are pre-configured with a genesis state that includes several pre-funded development accounts.
- 🧑‍⚖️ One development account (`ALICE`) is used as `sudo` accounts.
