How to become a Blockchain developer

It is becoming more and more apparent that we are living in the ‘era of the Blockchain’. It is going to play a massive role in our future, and the potential impact of this nascent technology is significant.

The Blockchain has become a $7 Billion industry, touching all corners of the globe and all sectors from finance to healthcare. It’s a powerful technological development and one that needs people’s time and attention if it is to realise its potential.

Learn more about the fundamentals of Blockchain, or gain hands-on experience with our CBP (Certified Blockchain Professional) course.


Becoming a Blockchain developer is a job for the future and an exciting one at that. Although the development of Blockchain is not much different from standard web development, the important thing to remember is that it will be developing specifically for Blockchain.

The journey to becoming a successful Blockchain developer starts with an understanding of the basics…

The basics of Blockchain

In a field as new as Blockchain, there are always some fundamental concepts that need immediate clarification:

What is Blockchain?

  • Blockchain is a chain of ‘blocks’, each containing data of value without any central supervision. This chain is immutable and cryptographically secure

  • Blockchain is decentralised. This means that there is no central authority, like a bank, supervising the network

  • With a decentralised system, in the absence of a central authority, there needs to be a consensus mechanism by which the network comes to a consensus on particular matters

  • Miners are users of the Blockchain who utilise computational power to ‘mine’ for blocks of data

One of the prime examples of a successful Blockchain system is the cryptocurrency Bitcoin. In order to gather an understanding of how Blockchain can be used to develop a widespread and elegant application, it is advisable to study the impact that Bitcoin has achieved.

This is doubly pertinent as it will help further your knowledge of crypto economics, an essential part of being a good Blockchain developer.

Learning the Blockchain process

It’s surprising how many people begin their Blockchain journey without having any experience of managing the system itself.

The best way to get a feel of how Blockchain works is to purchase some cryptocurrency. You don’t have to invest in an enormous portfolio right away, but owning a few coins in a basic online wallet will allow you to understand the landscape you want to help develop further.

Start coding for Blockchain

In Blockchain development, all transactions must be deterministic; A+B must always equal C. In order to achieve this, the solution is isolation. To isolate all transactions from non-deterministic elements in the code. People who develop strong skills in coding are highly desirable in this field.


However, there are some coding languages that better fulfil the needs of Blockchain than others. To develop Blockchain, you need to have at least a basic knowledge of C++ and Javascript.

Fun fact: Satoshi Nakamoto actually wrote the Bitcoin source code in C++.

Another thing to bear in mind when learning code for Blockchain is that you must always keep pace with the network and all the demands that it entails.

Stay up to date with the Blockchain

One of the most crucial things that anyone starting a career as a Blockchain developer can do is to constantly keep their ears open regarding news and changes in the technology.

This will help you know what employers are looking for in a Blockchain developer – what qualities, techniques and knowledge they require.

Becoming a Blockchain professional is an extremely rewarding career path. It will require a lot of initiative on your part, but luckily we offer the CBP (Certified Blockchain Professional) course that will set you well on your way.

With this world-class training, you’ll gain certification, technical insight, hands-on experience as well as the fundamentals of Blockchain. Contact us today to learn more.
