Why take this course?

Why should you take this course?

Allow me to put on my salesman hat, and respond that the real question is "why shouldn't you take this course"?

The course includes Python, Blockchains, Cryptocurrencies, Web Development (Backend and Frontend), JavaScript, React JS, React Hooks and more. By investing in this course, you're really getting your bang for your buck.

Want to add learn software programming, while adding relevant languages/technologies to your portfolio? Well then, this course is perfect for you. According to stackoverflow (2022 developer survey), Python and Javascript are the most popular languages/technologies. React.js is the most loved web framework. And there's no doubt that blockchains and cryptocurrencies are on the cutting edge of modern technology.

Want to learn Python and/or JavaScript? This course is for all levels. If you're a newcomer, you'll get a from-scratch experience. But the course journey is completely in your hands. If you're more experienced, feel free to skip the introductory sections for Python and JavaScript to get right into building the project.

The course is designed to help you achieve three main goals:

  • Learn Python and Backend Web Development.

  • Build a Blockchain and Cryptocurrency Project that you can add to your portfolio.

  • Learn JavaScript, Frontend Web Development, React.js, and React Hooks.

The course's main project is to build a blockchain and cryptocurrency. With a blockchain and cryptocurrency system as the main goal, you will go through a course journey that starts with backend development using Python. Then, you will transition to frontend web development with JavaScript, React.js, and React Hooks.

Here's an overview of the overall course journey:

  • Get an introduction of the Python Fundamentals.

  • Begin building the Blockchain Application with Python.

  • Test the Application using Pytest.

  • Incorporate the crucial concept of Proof of Work into the Blockchain.

  • Enhance the application to prepare for networking.

  • Create the Blockchain network using Flask and Pub/Sub.

  • Integrate the Cryptocurrency, building Wallets, Keys, and Transactions.

  • Extend the network implementation with the cryptocurrency.

  • Transition from Python to JavaScript with a "From Python to JavaScript" introduction.

  • Establish frontend web development skills and begin coding with React.js.

  • Create the frontend portion for the blockchain portion of the system.

  • Complete the frontend by building a UI for the cryptocurrency portion of the system.

In addition, here are the skills that you'll gain from the course:

  • How to build a blockchain and cryptocurrency system from scratch.

  • The fundamentals of python - data structures, object-oriented programming, modules, and more.

  • The ins and outs of hashing and sha256.

  • Encoding and decoding in utf-8.

Questions you may have:

Can I use the course project for my own software product?

Yes! Feel free to use the course project as the foundation for your own software product/company. The course code is open source. And I'm happy to provide advice via the Q&A section, or direct messages.

Can this course help me find employment?

Taking this course will turn you into both a software engineer, and a specialized blockchain engineer. This position is a new one in the software industry. And the demand is high. But the supply is low. So open a ton of doors by becoming an in-demand engineer with a fully deployed blockchain and cryptocurrency in your portfolio!

What is the difference between this course and your other courses on building a blockchain and cryptocurrency?

This is a remastered version of my other blockchain courses, using Python this time! Since Python is a language that can greatly serve you in your future with software engineering and/or the blockchain, this course is here with Python as a main emphasis.

In addition, a lot of the blockchain logic has been improved, with additional methods and concepts! This version of the project is definitely more secure, more thorough, and more complete.

Here are snippets from what students have said about my blockchain and cryptocurrency courses in the past:

"Outstanding course - I have a fully working and tested blockchain thanks to this course! David was super helpful in the Q&A, and did an excellent job of breaking everything down." - M.R.

"Excellent! The basic blockchain code is introduced early on. Explanations are very clear" - D.A"

"David has done such an amazing job with this course! He is patient and walks you through blockchain concepts from start to finish… A very solid foundation!" - K.I.


***

Ultimately, this course is a learning experience like no other. It's packed with languages and technologies from Python, to the blockchain, to React.js, and everything in between. On top of that. It’s an opportunity to become a pioneer in such a young and promising field.

So, hopefully, I'll see you in the course!
