# cennznet-runtime-template
Template project for CENNZnet / Substrate runtime & module development
# Building
Install Rust:
```bash
curl https://sh.rustup.rs -sSf | sh
```
Install required tools:
```bash
./scripts/init.sh
```
Build the WebAssembly binary:
```bash
./scripts/build.sh
```
Build all native code:
```bash
cargo build
```
# Run
You can start a development chain with:
```bash
cargo run -- --dev
```
Detailed logs may be shown by running the node with the following environment variables set: `RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev`.
If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet with two validator nodes for Alice and Bob, who are the initial authorities of the genesis chain that have been endowed with testnet units. Give each node a name and expose them so they are listed on the Polkadot [telemetry site](https://telemetry.polkadot.io/#/Local%20Testnet). You'll need two terminal windows open.
We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at `/tmp/alice`. The bootnode ID of her node is `QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN`, which is generated from the `--node-key` value that we specify below:
```bash
cargo run -- \
--base-path /tmp/alice \
--chain=local \
--alice \
--node-key 0000000000000000000000000000000000000000000000000000000000000001 \
--telemetry-url ws://telemetry.polkadot.io:1024 \
--validator
```
In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database stored locally at `/tmp/bob`. We'll specify a value for the `--bootnodes` option that will connect his node to Alice's bootnode ID on TCP port 30333:
```bash
cargo run -- \
--base-path /tmp/bob \
--bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN \
--chain=local \
--bob \
--port 30334 \
--telemetry-url ws://telemetry.polkadot.io:1024 \
--validator
```
Additional CLI usage options are available and may be shown by running `cargo run -- --help`.
# Connect with UI
- Open https://cennznet.js.org/cennznet-ui/#/settings
- Change endpoint to Local Node
- Click Save & Reload
- Now you should be able to interact with the node
# Create new module
A [template module](runtime/src/template.rs) is provided which can be used as a start point for new module development.
