Become a Blockchain Developer: The Right Way

Many industry leaders provide roadmaps on how to learn blockchain development. In that case, why should we care? This plan goes beyond simply outlining the what, why, and how of studying this exciting new technology. In addition to preparing you for the next step in the process, this article gives you a leg up once you've arrived at the finish line. This article is based on the experience I (an aerospace engineer) gained as a freelance developer over a year. This article further discusses the areas in which one should concentrate in order to be hired for a full-time position or to succeed as a freelancer.

Anticipated Results


If you are just starting out as a developer, this roadmap will show you the steps to take to become a seasoned expert with enough experience to land a good job or launch your own successful venture.


This roadmap is unique in its emphasis on both novice programmers and web2 developers interested in making the jump to web3 work. If you are a web2 developer who is struggling to find work, you may want to choose this route to hone your craft.

Web2 expert

If you are an experienced web2 developer, you can move on to point 4. If you already grasp the fundamentals of blockchain technology, you can move on to point 6. You'll learn a lot and have enough finished work to showcase in your portfolio. This will greatly ease your transition.

Specialist in Web3

Feel free to skip ahead to point 6 and look over the resources. This may assist you in locating resources that you have not previously encountered.

How should one go about mastering this intriguing technology? In the competitive blockchain development market, how can you make yourself stand out as a leader and a sought-after developer? A guide to becoming a successful blockchain developer has been developed by Freeflow, a marketplace designed for web3 developers and clients.

Before diving into the roadmap, we want to give you some helpful advice for developing your blockchain skills.

"Don't Google, Twitter is the new Google for blockchain technology."

On September 15, 2021, I embarked on this adventure. I spent a whole month searching the internet for materials before I found anything worthwhile. But after a day of strategic Twitter use, I had access to a variety of blockchain development courses.

"Skip Facebook and Instagram; your buddies are on Discord."

It should be noted that this is not a "get rich quick" or "become a blockchain developer quickly" type of thing. A quality developer is the centerpiece of this road map. Learning to code is a lengthy process. It requires hard work, reliability, and regular practice. Check this article, “Teach Yourself programming in 10 years”. Please bear in mind that while it won't take 10 years to become a blockchain developer, you also won't become one in a week. 


So, without further ado, let's get down to the roadmap.

  1. 1. Find out what makes Web3 different from Web2 and Web1


The basics must be mastered.


a. GeeksforGeeks Draws Parallels Between Web 1.0, Web 2.0, and Web 3.0. Excellent information for anyone seeking clarity.

b. Learn with Whiteboard presents: What is Web 3.0 Explained | Web 1.0 vs. Web 2.0 vs. Web 3.0 Crypto.

2. Master the fundamentals of computer science


Entering blockchain technology as a developer without proper programming knowledge will quickly end your career. Mastering the fundamentals is crucial for rapid development.


We recommend that you complete the Harvard University CS50x course, which is a world-renowned course led by Prof. David J Malan.

Helpful Tips
