Build a Blockchain from Scratch in Go

20 ratings

★ Get ready for Web 3.0 and learn blockchain fundamentals.

What can you expect?

This eBook is not specific to any particular blockchain. Opposite. It contains various peer-to-peer, blockchain and cryptographical design patterns useful for any software developer who wants to expand his programming career and learn new concepts. Majority of the components are from Bitcoin and Ethereum blockchain implementations.

I can't promise the blockchain way of programming will be easy, but this eBook will turn you into a blockchain developer, expand your career prospects, and open you up to a whole new community of amazing forward thinkers.

Chapter by chapter, you will build a full peer-to-peer, autonomous blockchain system in Go and learn all standard blockchain components!

1) You will build a peer-to-peer system from scratch

You will get access to a private Github repository where you will start with 0 lines of code and end-up with 13+ branches with complete executable source-code. [Full screen]

PS: Don't worry if anything on the screen makes sense yet, it will once you go chapter by chapter; release by release.

peer-to-peer blockchain system in action

2) You will secure the system with a day-to-day practical cryptography

No boring theory. Only modern practices. [Full screen]

elliptic curve cryptography

3) You will implement Bitcoin, Ethereum and XRP backend components 

From diagrams of mining algorithms to actual, implemented and working crypto wallets for storing the mined tokens and all other fundamental components that make blockchain special. [Full screen]

decentralized consensus

4) You will write unit tests and integration tests for all core components

You will test your cryptographic functions, a Bitcoin's like Proof of Work mining algorithm and other key components. [Full screen]

Why should you learn blockchain?

★ Because you get to work on a cutting-edge technology while other 10 million developers are still applying for Java/PHP/JS legacy positions. 

Blockchain is changing industries, building communities and shifting the job market.

It's certainly not for everyone, but it could be for you if:

  • You're an early adopter and seek the next innovative techYou already know how to develop CRUD and REST API for a monolith.Relational databases are too stable, and honestly, a bit boring.Micro-services are a nightmare.Blockchain database has a unique peer-to-peer autonomous design. You learn Go, Cryptography, Event-Based Architecture, and other concepts required for Web 3.0 vision.

  • You want higher earnings, more autonomy + WFHBlockchain Development is the most emerging job position, with unparalleled 33x growth.
    High demand and few good developers, means you'll be able to set the price, and terms you're happy with.Remote blockchain developers can earn up to $200,000.

  • You want to believe in the work that you're doingWeb 3.0 core principles aim to reduce corruption in the world and improve transparency in all industries from shipping, manufacturing, trading, and others.Focus on data privacy. There is no reason your Instagram vacation picture, should be stored in a commercial database for sale to advertisers.Free speech censorship, a basic human right.

★ It's how you'll expand your programming career!

What's the best thing about this book?

This is a great product to get started with blockchain development because it contains theory, design diagrams as well as full source code.

It's like a heavy tutorial but written in an easy to read story with a lot of fun facts about the blockchain ecosystem and illustrations explaining all blockchain concepts component by component.

The new programming skills you will learn are also applicable to your current/next job. You will practice real-world Go programming.

You will understand blockchain technology itself. If you fall in love with the tech, you will have a choice to enroll in my individual coaching and further specialize in Ethereum application development.

  • Structured, organized content
  • To get you started quickly
  • With full Github source code
  • And easy to follow storyline
  • Enhanced with architecture diagrams
  • Support from Lukas (author) directly from the first chapter in a private Discord room
  • While having fun coding new exciting tech
  • Integrated into Lukas' coaching system with tailored next steps after you finish the book

Looking forward to be working with you.


Student A - wants to learn Go and Blockchain:

"This book helped me understand blockchain. I had no clue about how it worked or how to build one from scratch. Lukas makes it very easy from the very beginning, even for someone like me, a software engineer with no previous experience in Go."

Jose A. Navarrete

Student B - wants challenge:

Student C - wants to learn distributed ledger fundamentals

"Back in the early days of bitcoin there was a great deal of explanation of what it as for, how it worked, great in depth detail of how it worked, and it was all a bit much. Landing me in the "what is the purpose of this?" camp. While I have dabbled in alt-coins over the years, my understanding of that basic question was still something I never really dug into. Recently I decided to try to understand it better, and my search lead me to The Blockchain Bar. The course material is great at walking through the theory of blockchain at an understandable level, with the added benefit of reading through code and running tests to help solidify the concepts."
