# Substrate Node Template
|
||||
|
||||
A new SRML-based Substrate node, ready for hacking.
|
||||
|
||||
## Build
|
||||
|
||||
Install Rust:
|
||||
|
||||
```bash
|
||||
curl https://sh.rustup.rs -sSf | sh
|
||||
```
|
||||
|
||||
Install required tools:
|
||||
|
||||
```bash
|
||||
./scripts/init.sh
|
||||
```
|
||||
|
||||
Build Wasm and native code:
|
||||
|
||||
```bash
|
||||
cargo build
|
||||
```
|
||||
|
||||
## Run
|
||||
|
||||
### Single node development chain
|
||||
|
||||
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`.
|
||||
|
||||
### Multi-node local testnet
|
||||
|
||||
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.
|
||||
|
||||
Optionally, 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 `QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR`, 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/QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR \
|
||||
--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`.
