Blockchain technology was initially used to create and manage the world’s first cryptocurrency, Bitcoin, but the administration of data and trade are likely to gain a positive change from this technology. 

Blockchain has already shown its potential in the private and public sectors through its high-security features and adaptability. From the speculations around the adaptation of blockchain in various sectors, it is a good idea to consider becoming a blockchain developer.

This is a great opportunity to start a career with a new technology that has so much potential and room for improvement.

Do you desire to become a developer of one of the most used technologies in the world? Not just become one but also earn a huge amount of money from it? 

This article has simplified the mystery behind this.

What Is A Blockchain?

Blockchain is a distributed digital ledger shared among the nodes of a computer network that comprises any type of data at its core. The data recorded in a blockchain could be cryptocurrency transactions, NFTs ownership and DeFi smart contracts. 

A blockchain stores data electronically in digital formats and ensures the security and authenticity of data.

The difference between the traditional database and blockchain is that blockchain is the structure of the data.

While a blockchain collects information in groups called ‘blocks’, the traditional database structures data into tables.

In a blockchain, information is stored in the blocks and when the storage capacity is reached, it is closed and linked to the previously existing one which forms a chain of data known as the blockchain.

Identical copies of a blockchain database are mostly held on multiple computers dispersed across a network instead of having a centralized administrator maintaining them in one location.  

Who Is A Blockchain Developer?

A blockchain developer is responsible for developing and optimizing blockchain protocols, drafting the architecture of blockchain systems, and developing smart contracts and web apps with the use of blockchain technology.

Functions Of A Blockchain Developer

The blockchain developer has numerous tasks which he must fulfil to be referred to as a full-fledged developer. His duties are not limited to some complicated issues like;

  • Performing a complicated analysis, design, test, development and debugging of the computer software for product hardware.
  • Create a network that allows for centralization or decentralization of data.
  • Execute backend programming using blockchain protocols.
  • Create front-end designs to satisfy customer demands.
  • Build and maintain smart contracts.
  • Develop computer system selection, program design and operating architecture integration.
  • Deploy understanding of various programming languages and platforms on a variety of systems.

However, the blockchain developer faces the challenge of fulfilling the criteria of a blockchain development project even though there may be a restriction due to old technology.

A blockchain developer needs specialized skills to fully understand the difficulties in the technological realities of developing decentralized cryptosystems and other processes that may have transcended the normal IT development skill-set.

How To Become A Blockchain Developer And Earn Millions

Given the volume of responsibilities and challenges faced by a blockchain developer which was discussed above, it becomes important that the question of “how to become a skilled blockchain developer?” emerges.

While some have some IT experience in some areas connected to blockchains, some others have no prior knowledge of computer programming or knowledge of blockchain technology.

In both cases, there are some steps to be taken before one can be called a blockchain developer.

1. Understanding The Basic:

The first thing to do is to get familiarized with the basics of blockchain technology by researching and learning about it. You can either learn by yourself or take a course on any online learning platform.

Ensure to dissect all the components of blockchain such as; consensus processes, hashing functions, decentralization, mining, security and cryptocurrencies at large.

Also learn about timestamp, block hash, block time, blockchain blocks, block index etc.

2. Engage In Hands-on Training And System Interaction:

Engage in practical training on blockchain technology like; downloading and utilizing pre-built wallets or dApps for knowledge of their operation.

Create wallet addresses and private keys, utilize them, and send cryptocurrency over two or more blockchains.

Understand the operations of exchange and smart contract platforms, and engage in developer conferences.

3. Learn To Code And Obtain Certification:

It’s a compulsory requirement that you will need a coding language if you must be a blockchain developer. You can enrol on a coding program at an institution or you can learn online.

Learn how to use coding languages like C++ and javascript in blockchain development. Also learn how to choose the best coding languages to optimise blockchain performance, how to manage blockchain resources with code, achieve the deterministic (isolation) nature of blockchain transactions with code and how to code all aspects of blockchain. In fact, endeavour to be an expert in code analysis.

4. Become A Blockchain Engineer:

By being part of a hackathon, part of a competition or an online blockchain training facility, you will become a blockchain engineer with a certification of your own.

Create your blockchain by creating the first block and then adding further blocks after which you validate the chain before using it.

5. Create A Smart Contract, Become Certified:

Just like you must have done as a part of the blockchain training facility, develop smart contracts by being familiar with their deterministic, terminable, and isolated characteristics. Get certified on this and utilize it to your best advantage.

6. Join A Practice Session For Blockchain Developers, Or Internship Program:

What’s the use of learning a skill without practice? Look out for some internship programs online and apply to as many as possible. You can even volunteer to work as a blockchain developer for some firms. The experience will help you build your portfolio and also develop your skill.

7. Look For Employment As A Blockchain Engineer Or Developer:

The last step is to find yourself a job which requires your skill as a blockchain developer. 

You may use conventional job hunting apps like Linkedin and Indeed to look out for opportunities for yourself.

Draft your CV to show all the relevant skills and experiences you have had as a blockchain developer.

When you come across any job, always pitch your skillset, experience, past and potential 

 to your potential employers.  


Blockchain technology is a leading pathway in the world today. Its highly secure, adaptable and decentralized nature has made it attractive to both the public and private sectors. This implies that the potential and growth of this technology have not been fully actualized, hence, there is room for more opportunities.

Becoming a blockchain developer is one way to reap the abundant good fruits of the blockchain.
