Hyperledger Fabric blockchain network from scratch

Question

I've been studying the Hyperledger Fabric framework reading the docs for quite a while now but I'm getting a little lost in the middle of all that info. My question is: Is there any guidelines/"Step by step" on how to design a blockchain network from scratch? If you are starting a new project, where do you start?

Because I think I would understand it way more quicker if I actually started coding a little instead of reading and reading and reading...

Thanks a lot!

Edit 1:

I've chosen @kekomal answer as the correct one but I'd like to thank @Isha Padalia for the awesome VS Code extension and tutorial.

Answer 1

If you are really interested in learning and diving into Hyperledger Fabric, avoid byfn script. It performs a lot of magic for building a very simple Hyperledger Fabric network. After that, you have a network that you don't know how has been created and you have absolutely no idea of how to start deploying your custom network. There are daily questions here from people who started that way and are absolutely lost.

I find interesting this tutorial: https://medium.com/beyondi/setup-the-hyperledger-fabric-network-from-scratch-b82913b47549. Take into account that it is a little bit outdated.

You can complement it with this newer tutorial: https://www.blockchainexpert.uk/blog/how-to-deploy-hyperledger-fabric-network-from-scratch. Don't only run the steps. Analyze the files in https://github.com/blockchain-expert/hyperledger-fabric-network-from-scratch. Try playing with configtx.yaml, crypto-config.yaml and docker-compose files to customize your network and understand what you are doing.

Customize your organizations, your consortiums, your ordering service, your peers... Create your channels, join them, update your anchor peers... And understand what you are doing.

After that, if your network had one orderer, deploy a new one with more than one (with Raft consensus). If your network was using cryptogen, deploy a new one using Fabric-CAs instead. Or you can follow by playing with chaincodes.

NOTE: Apart from Hyperledger Fabric itself, it is essential to have basic notions of docker and PKI.

You are a beginner in Hypelredger fabric development then you have first cleared the concept of the orderer, peer, CA, and organization concept. And then first you have to start IBM Blockchain Platform VS Code extension for fabric. It will provide a local fabric environment to create, test and deploy a fabric smart contract. Also generate 1 peer, 1 orderer, 1 CA service under VS code environment.

Here is a link to start development with VS code extension.

Hope it will help you:)
