Mini - A minimal Cosmos SDK chain

This repository contains an example of a tiny, but working Cosmos SDK chain. It uses the least modules possible and is intended to be used as a starting point for building your own chain, without all the boilerplate that other tools generate. It is a simpler version of Cosmos SDK's simapp.

Minid uses Cosmos-SDK v0.52.x with the v2 core layer.

Note

This is an example chain for the Cosmos SDK v2. Looking for the v0.52.x example? Check the v0.52.x branch. Looking for the v0.50.x example? Check the v0.50.x branch.

How to use

In addition to learn how to build a chain thanks to minid, you can as well directly run minid.

Prerequisites

  • Install Go as described here.
  • Add GOPATH to your PATH:
    • export PATH="$PATH:/usr/local/go/bin:$(/usr/local/go/bin/go env GOPATH)/bin"

You are all set!

Installation

Install and run minid:

git clone [email protected]:cosmonity/chain-minimal.git
cd chain-minimal
make install # install the minid binary
make init # initialize the chain
minid start # start the chain

Troubleshoot

After running make install, verify minid has been installed by doing which minid. If minid is not found, verify that your $PATH is configured correctly.
