This guide provides a step-by-step process to set up and launch a node for a Cosmos SDK-based blockchain. For this example we will clone Juno and launch it as an independant chain with one validator node, but you can use your own Cosmos SDK chain, as the process is similar.
In this tutorial, we will scaffold a front-end application using Ignite CLI. Requirements: * Ignite CLI version 0.26.1 * Golang * NPM Remove Old Installation of Ignite If you already have Ignite installed and the beta blockchain from the other tutorials, you can remove it with this command: sudo rm -r
Why Create Modules? Modules provide modularity and compartmentalize the code, making it easier to manage and maintain. For example, if Yoda wants to track the Sith as well as the Jedi, he can create types and functions specifically related to Jedi and Sith tracking and keep them separate. Step 1:
In our previous tutorialLink, we created a custom message type, but it had a few limitations, namely: 1. It does not update a data store. 2. It cannot be deleted from the data store. 3. There is no straightforward way to look it up from the binary other than by
In this tutorial, we will create a custom message type. If you think about 1st Generation Blockchains, they were primarily built to send numbers between addresses in the form of cryptocurrency. However, Cosmos SDK chains allow you to send all sorts of data types—anything that can be encoded into
To complete this tutorial, you will need an account with a VPS cloud provider. There are many options available, such as: * Heroku * Digital Ocean * Akamai (Linode) For this tutorial, we will use Digital Ocean. However, feel free to use any provider you prefer. Step 1: Create a New Project on
While it is recommended to use Mac or Linux for Cosmos SDK chain development, Windows users can set up their environment using the Windows Subsystem for Linux (WSL). This guide will walk you through installing and configuring Ubuntu on WSL, along with necessary dependencies. Step 1: Install Ubuntu for Windows
In order to build Cosmos SDK blockchains and use Ignite CLI, you will need to to have the following: * Install Golang * Update Environment Variables * Install Dependancies Install Golang: FYI - Cosmos SDK was written in Golang. On Mac: Install Link On Linux: Install Link Update Environment Variables You should have
In this tutorial you will need: * A Cosmos SDK Chain Running (we will launch one) * Leap Wallet Chrome Extention Leap Wallet Link To get started, lets build a quick blockchain using Ignite CLI (Note: for this tutorial I am using Ignite Version 0.26.1) If you do not have
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
Bootstrap an Example Chain There are two examples, I would make here: * Bootstrap a blockchain running on your local host. Basically do all the code you need to get an example testchain up and running. * Bootstrap a node to an existing network. (I will link to this when published). By
For this tutorial we will be using two seperate chains (Alpha & Omega) scaffolded with Ignite CLI. Steps: * Install Ignite CLI * Install Hermes App for Ignite CLI * Scaffold Alpha Blockchain * Add alpha.yml config file * Scaffold Omega Blockchain * Add omega.yml config file * Start Alpha & Omega chains * Configure the
