Template Node
A new SRML-based Substrate node, ready for hacking.
Building
Install Rust:
curl https://sh.rustup.rs -sSf | sh
Install required tools:
./scripts/init.sh
Build the WebAssembly binary:
./scripts/build.sh
Build all native code:
cargo build
Run
You can start a development chain with:
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. 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:
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:
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.
