**Whitepaper:** [Gitbook](https://g6-networks.gitbook.io/g6-networks/)

## Getting Started with Building

Ensure all necessary dependencies are installed according to your platform’s [Substrate installation guide.](https://docs.substrate.io/install/)

### Build

Use the following command to build the node without launching it:

```sh
cargo build --release
```

### Single-Node Development Chain

The following command starts a single-node development chain that doesn't
persist state:

```sh
./target/release/g6-solo-node --dev
```

To purge the development chain's state, run the following command:

```sh
./target/release/g6-solo-node purge-chain --dev
```

To start the development chain with detailed logging, run the following command:

```sh
RUST_BACKTRACE=1 ./target/release/g6-solo-node -ldebug --dev
```

### Run with docker

You need to have docker installed on your system

#### Build

```sh
docker compose -f ./docker_g6/compose_files/solo_chain/builder/docker-compose.yml up
```

#### Run
```sh
docker compose -f ./docker_g6/compose_files/solo_chain/runner/docker-compose.yml up
```

#### Run the live chain
- build the chain
- create and insert keys with the generate_validator_keys.sh from the Scripts project
You will have your secrets in a data folder. There are secrets inside which you should NOT share with anybody.
```shell

```

Run the blockchain

```shell
$SOLO_CHAIN_NODE_EXECUTABLE \
        --base-path "$BASE_PATH" \
        --chain "$RAW_CHAINSPEC_FILENAME" \
        --port "$CHAIN_PORT" \
        --rpc-port "$RPC_PORT" \
        --validator \
        --name "$NODE_NAME"
```
BASE_PATH = the path to the data folder we created with the generate script.
SOLO_CHAIN_NODE_EXECUTABLE = the path to the node executable E.g. <solo_chain_project>/target/release/g6-solo-node
RAW_CHAINSPEC_FILENAME = the raw chainspec. The live raw chainspec is stored in this project
CHAIN_PORT=9944
RPC_PORT=30301
NODE_NAME= any unique name

### Key generation 

```sh
./target/release/g6-solo-node key generate --output-type json
```
Example output
```txt
{
  "accountId": "0x9e6a8d5406599378f39784cb2f31f8a848d4605177da43d9e1227026a970e51c",

  "ss58PublicKey": "5FeR5LJ8jR6SRXeKXFEn61H2ztWxTw4Vvpz9vRrVdhcpuvKk"
}

```
Substrate supports different key types (e.g., sr25519, ed25519, or ecdsa). You can specify the key type using the --scheme flag
```sh
./target/release/g6-solo-node key generate --scheme sr25519 --output-type json
```
Generate Keys for a Specific Network
```sh
./target/release/g6-solo-node key generate --network polkadot
```
Help Command for Details: To explore all available options, use the --help flag:
```sh
./target/release/g6-solo-node key --help
```
