A new Cumulus-based Substrate node, ready for hacking ☁️
This project is a fork of the Substrate Developer Hub Node Template.
Follow these steps to prepare a local Substrate development environment 🛠️
If necessary, refer to the setup instructions at the Substrate Developer Hub.
Once the development environment is set up, build the node template. This command will build the Wasm and native code:
cargo build --releasePolkadot (rococo-v1 branch):
cargo build --release --features real-overseer
./target/release/polkadot build-spec --chain rococo-local --raw --disable-default-bootnode > rococo_local.json
./target/release/polkadot --chain ./rococo_local.json -d cumulus_relay1 --validator --bob --port 50555
./target/release/polkadot --chain ./rococo_local.json -d cumulus_relay0 --validator --alice --port 50556
Substrate Parachain Template:
# this command assumes the chain spec is in a directory named polkadot that is a sibling of the working directory
./target/release/parachain-collator -d local-test --collator --alice --ws-port 9945 --parachain-id 200 -- --chain ../polkadot/rococo_local.json
Refer to the upstream Substrate Developer Hub Node Template to learn more about the structure of this project, the capabilities it encapsulates and the way in which those capabilities are implemented. You can learn more about The Path of Parachain Block on the official Polkadot Blog.
