Hyperledger Fabric Mastery Roadmap

Welcome to the Hyperledger Fabric (HLF) Mastery Roadmap! This guide is designed to take you from beginner to expert in HLF by implementing real-world scenarios.

📌 Day 1: Understanding Hyperledger Fabric & Setting Up the Network

🎯 Objectives:

Understand Hyperledger Fabric architecture (Orderers, Peers, MSPs, Channels, Chaincode, CouchDB vs LevelDB, etc.).
Set up a minimal Fabric network using fabric-samples/test-network.
Deploy a custom Fabric network using cryptogen and configtxgen.

📂 Folder Structure

Your repository will have the following structure:

hlf/
 ├── fabric-samples/   # Fabric sample network
 ├── day1/             # Documentation for Day 1 progress
 │   ├── day1.md       # Steps, commands, and explanations for Day 1
 │   ├── assets/       # Diagrams or images for understanding HLF

📖 Learning & Implementation Steps

1️⃣ Understanding Hyperledger Fabric Architecture

Read Fabric Docs: Hyperledger Fabric Docs
Key Components:
- Orderers: Maintain transaction order.
- Peers: Maintain the ledger and execute chaincode.
- MSP (Membership Service Provider): Handles identity & authentication.
- Channels: Private communication pathways.
- Chaincode: Smart contracts running on peers.
- Databases: CouchDB (rich queries) vs LevelDB (key-value store).

2️⃣ Setting Up Fabric Samples Network

Clone Fabric Samples and install prerequisites:

git clone https://github.com/hyperledger/fabric-samples.git
cd fabric-samples/test-network
./network.sh up createChannel -ca

Verify network:
```
docker ps
```

3️⃣ Bootstrapping a Custom Fabric Network

Generate crypto material using cryptogen:

cryptogen generate --config=./crypto-config.yaml --output=crypto-config/

Create configtx.yaml and generate genesis block:

configtxgen -profile OrdererGenesis -channelID sys-channel -outputBlock ./genesis.block

Start network using Docker Compose:

docker-compose -f docker-compose.yaml up -d

Verify network logs:
```
docker logs peer0.org1.example.com
```

✅ Tasks for Day 1

✔ Clone fabric-samples and explore test network. ✔ Understand Fabric network components and configurations. ✔ Create day1.md and document all steps with issues faced. ✔ Bootstrap a custom Fabric network. ✔ Push updates to GitHub repository under day1/ folder.

💡 Next Steps: Proceed to Day 2 - Creating and Managing Channels 🚀
