Create a Simple Cosmos SDK Blockchain
When creating a blockchain, we have a few options. 1) Clone the repo for an existing chain like Juno link 2) Code evertything ourselves or 3) Use a CLI program that allows us to generate all the boilerplate code for a Cosmos SDK based chain, for this I will use Ignite CLI, which allows a user to do exactly that.
To start we can create a project directory or for simplicity, let's create one in our home folder.
cd $HOME
Now we will generate our blockchain project, in this case I will call the chain alpha. I will also give it an address prefix called alpha.
ignite scaffold chain beta --address-prefix beta
Once completed you can change your directory to the project directory with this command:
cd beta
I would suggest taking the time to familiarize yourself with the files created, note nearly all Cosmos chains will have similar folders like x proto etc
Once we have changed our directory, we can start our chain with one command:
ignite chain serve
If this works, your chain is now running(creating blocks) on your local host.
You can view your chains command with its binary as follows:
betad --help
