How to Become a Blockchain Developer: A Step-by-Step Guide

How to become a Blockchain developer? A step by step guide explaining how to become

If you’re reading this, then you’re probably interested in how to become a blockchain developer. And you’re in luck – we’re going to show you how! But first, let’s answer some common questions about blockchain development: What is it? What skills do you need? What education is required? And more. Once you have a good understanding of blockchain development, we’ll show you how to get started with your own journey to becoming a successful blockchain developer!

The profession: What is a blockchain developer?

A blockchain developer is someone who specializes in developing applications for the blockchain platform. Blockchain developers use their skills to create decentralized apps, smart contracts, and other digital assets. They also help to maintain and improve the blockchain network.

What do Blockchain developers do and what do they do?

Some of the responsibilities of the Blockchain Developer are:

  • Support and development of projects
  • Communication with remote developers
  • Creation of blockchain data analytics services (bitcoin, ethereum and other networks).

What skills do you need to be a blockchain developer?

In order to be a successful blockchain developer, you will need to have strong technical skills. This includes being able to code in languages like Solidity, Java, and C++. You should also have a good understanding of what is blockchain and how the blockchain works and how to build decentralized apps. Other skills you should have are:

  • Knowledge of web3.js, rest api
  • Understanding the principles of blockchain projects and web 3.0
  • Attention to detail, responsibility
  • Strong knowledge of JavaScript/TypeScript
  • Strong knowledge of React
  • js/php/go

Additionally, it is helpful if you are familiar with tools like Truffle and Ganache.

What education is required to be become a blockchain developer?

There is no one-size-fits-all answer to this question, as the education requirements for blockchain developers can vary depending on the specific role. However, most employers will require you to have at least a bachelor’s degree in computer science or a related field. Additionally, it is helpful if you have experience working with blockchain technology.

Now that we’ve answered some common questions about how to become a blockchain developer, let’s take a look at how you can get started on your own journey!

Is Computer Science really important to become a Blockchain Developer?

Computer science is the study of algorithms and data structures that enable efficient computing. It is the foundation upon which software engineering and artificial intelligence are built.

A strong understanding of computer science is essential for anyone looking to develop applications on the blockchain. This is because the blockchain relies heavily on cryptographic algorithms for security and consensus.

In addition, smart contracts, which are programs that run on the blockchain, also need to be well-designed in order to function correctly.

Smart contract developers need to have a solid understanding of programming languages and software development in order to create effective contracts.

Overall, computer science knowledge is important for blockchain developers because it helps them to create secure and efficient applications. Without a strong understanding of computer science, it would be very difficult to develop applications on the blockchain.

Step-by-Step Guide on How to become a Blockchain Developer

  1. Learn the basics of algorithms and computer science

Everything starts with education. Find the best course for Computer Science and sign up for it ASAP. 

Top 5 computer science universities in the world:

  1. Massachusetts Institute of Technology (MIT)

  2. Stanford University

  3. Carnegie Mellon University

  4. University of California, Berkeley (UCB)

  5. Princeton University

Other options are:

  • Self-study – all kinds of YouTube videos, books, forums, tutorials, etc. Pros: Cheap or very inexpensive. Cons – there is no consistency, self-study may turn out to be ineffective, the acquired skills may be unclaimed by the employer;
  • Online learning. You can take the course on one of the educational platforms. Such courses are designed for people with no special training, so they will suit most people. Usually, the emphasis in online learning is on practice – this allows you to quickly replenish your portfolio and get a job immediately after training.

Tip: You should check out DappUniversity, especially if you’re a beginner. Their teacher mainly focuses on smart contracts and DApp development. Another great source is  Blockgeeks .

2. Learn how to code

The first step is to learn how to code. If you’re not already familiar with coding languages like Solidity, Java, and C++, then you’ll need to learn them before you can start developing for the blockchain platform. You can find resources to help you learn how to code on the internet, or you can take a coding class at your local community college.

3. Learn how the blockchain works

Once you’ve learned how to code, the next step is to familiarize yourself with how the blockchain works. You can do this by reading books and articles about blockchain technology, or by taking an online course. Once you have a good understanding of how the blockchain works, you’ll be ready to start developing decentralized apps!

4. Build your own DeFi project

Next up, it’s important that you build your own DeFi project. Make sure that you follow this list:

  • Choose the platform you want to develop for.
  • Learn how to code smart contracts.
  • Test your contracts on a testnet.
  • Deploy your contracts on a mainnet.
  • Repeat untill you finally get it.

Start small. Submit your code to Github and show your projects to other people. You can use Heroku or Github Pages to build your frontend. The development of smart contracts for the Ethereum testnets is free.

5. Asses your shills as a Blockchain Developer

It is likely that after working with many different technologies, you have your own “favorite” stack of technologies that you find most convenient. However, Blockchain Development has its specifics.

Experience in full-stack development is a huge advantage, but not a requirement. Perhaps you only focused on the backend and didn’t touch the web design. Your main job so far may have been building components with React, but the mere mention of microservices made you cringe.

The most important thing is that you know your strengths and weaknesses from generic development. 

6. Apply for a Blockchain Developer job

When you have a new portfolio that represents you online as a blockchain developer, update your outdated resume. Describe recent skills and apply for a blockchain-related position. 


Building your first DeFi project as a Blockchain Developer: What technologies should you know?


First, start studying Solidity . This is the Ethereum smart contract language. This is the base for any decentralized application on the Ethereum platform.

Node and React

Explore further node and React , they are very popular for front-end development and are among the tools of choice for most DApp (decentralized application) developers. Check out redux too.

Truffle Suite

Rembeber that  Truffle Suite  helps you to “glue” your Solidity code to the frontend. With Solidity, Node,web3js and React you can develop, test and deploy decentralized applications from Truffle Suite.
