If you followed the instructions to build the node, you my proceed to launch your first blockchain.
Before we launch our node we will purge any chain data. If you've followed the instructions exactly, you will not yet have any chain data to purge, but on each subsequent run, you will, and it is best to get in the habbit of purging your chain now. We will start our node in development mode (
# Purge existing blockchain data (if any) ./target/release/kitchen-node purge-chain --dev # Start a fresh development blockchain ./target/release/kitchen-node --dev
You should now see blocks created on the console.
You can navigate to the Polkadot-JS Apps user interface. This is a general purpose interface for interacting with many different Substrate-based blockchains including Polkadot. From now on we'll call it "Apps" for short. Before Apps will work with our blockchain, we need to give it a little chain-specific information known as the "types". You'll learn what all this means as you work through the recipes; for now just follow the instructions.
If you are not clicking the link above but visiting Apps directly, by default Apps connects to Polkadot Kusama network. You will need to switch the connecting network to your locally running network, with only one node, by clicking on the network icon on Apps top left corner.
Some browsers, notably Firefox, will not connect to a local node from an https website. An easy work around is to try another browser, like Chromium. Another option is to host this interface locally.
If you're not already on the
Settings -> Developerpage, please navigate there. Copy the contents of
runtimes/super-runtime/types.json into Apps.
As you work through the recipes, you will use the Chain State tab to query the blockchain status and Extrinsics to send transactions to the blockchain. Play around for a bit before moving on.
