In this tutorial we will learn and practice how to start a blockchain network with a validator/authority set of your choosing using Substrate.
Install the Node Template
You should already have version
v2.0.0-rc5 of the Substrate Node Template compiled on your computer from when you completed the Create Your First Substrate Chain Tutorial. If you do not, please complete that tutorial.
Experienced developers who truly prefer to skip that tutorial, you may install the node template according to the instructions in its readme.
What you will be doing
Before we even get started, let's lay out what we are going to do over the course of this tutorial. We will:
- Launch a Substrate blockchain network based on a template project.
- Generate ed25519 and sr25519 key-pairs for use as a network authority.
- Create and edit a chainspec json file.
Sound reasonable? Good, then let's begin!
