Welcome to your lightning-fast journey into the world of Harmony, a blockchain protocol designed with sharding to enhance scalability and performance! This guide will walk you through setting up your development environment, building the Harmony binary, running tests, and troubleshooting common issues along the way.

Prerequisites for a Smoother Setup

Before diving into the installation process, make sure you have the following tools at your disposal:

• Go 1.22.5
• GMP and OpenSSL – Install these using package managers for your OS.
• Docker – Essential for testing and running your environment smoothly.
• Bash 4+ – Make sure your Bash version is appropriate for running scripts.

Installation Steps

Now let’s get you set up! Follow these steps closely:

Step 1: Create Directories

mkdir -p $(go env GOPATH)src/github.com/harmony-one
cd $(go env GOPATH)src/github.com/harmony-one

Step 2: Clone the Necessary Repositories

git clone https://github.com/harmony-one/mcl.git
git clone https://github.com/harmony-one/bls.git
git clone https://github.com/harmony-one/harmony.git
cd harmony

Step 3: Build the Harmony Binary

go mod tidy
make
bash scripts/install_build_tools.sh

Understanding the Build Process: An Analogy

Imagine you are building a model of a car. You need different parts like wheels, a chassis, and an engine. Your Harmony binary is like this model car—it needs various components (libraries) to function properly. When you execute the commands:

• go mod tidy: This helps you gather all necessary parts.
• make: This is where all those parts come together to form your completed car.

To make sure everything is working perfectly, it’s essential to install tools that help assemble your model without missing any pieces. That’s what bash scripts/install_build_tools.sh does—it ensures you have the right tools for the job.

Using Docker for Development

If you prefer a contained environment, you can build and run Harmony within Docker:

cd $(go env GOPATH)/src/github.com/harmony-one/harmony
make clean
docker build -t harmony .

Testing Your Setup

To ensure your Harmony setup works as intended, you can run various tests. Use the following command:

make test-go
make test-rpc

These tests are like quality checks for your model car; they verify that every part functions correctly before taking it for a drive!

Troubleshooting Issues

Sometimes, things might not go as planned. Here’s how to solve some common problems you may encounter:

• Unknown Command Errors: Ensure you have installed Go on your machine and that your environment variables are correctly set. If this persists, revisit the installation steps.
• Docker Errors: Ensure Docker is running properly before executing the build commands. Refer to the official documentation for details.
• Dependency Issues: If you find missing modules, try running go mod tidy again.
