How to become a Blockchain Developer, Know its Types, Roles, and Skills

Blockchain technology enhances security and speeds up the exchange of information in a way that is cost-effective and more transparent. The importance of blockchain has attracted the attention of organizations in various sectors with the banking sector being the most active.


What is Blockchain?

A blockchain is a decentralized digital ledger that stores transactions on thousands of computers worldwide. Blockchain technology enhances security and speeds up the exchange of information in a way that is cost-effective and more transparent. The importance of blockchain has attracted the attention of organizations in various sectors with the banking sector being the most active. Blockchain has resulted in the growth of thousands of new job positions and new startups ranging from mobile payment solutions to healthcare applications.



In fact Blockchain is one of the top emerging technology domain in the current scenario of IT world. The global market for blockchain technology is expected to reach approximately $20 billion by the year 2025. There are various IT giants like Samsung, IBM, Capgemini which are offering great career opportunities for Blockchain professionals and you can consider becoming a Blockchain developer to make a meaningful and successful career.

Who is a Blockchain Developer?

Blockchain developers are technical professionals who work on blockchain technology and are responsible for related tasks, such as designing the blockchain protocol, creating smart contracts, etc. A blockchain developer has a set of knowledge and skills to develop and optimize smart contracts based on blockchain as well as blockchain architecture and protocols. They also deal in 3D modeling, 3D design, 3D content development as in game development.

Blockchain developers can mainly be divided into two types – blockchain software developers and core blockchain developers.

1) Blockchain Software Developers

Blockchain software developers develop and implement the design as planned by the core developer, such as -


- They develop dApps.


- They implement smart contracts as designed by the core developers.


- They ensure that the DApp runs as planned.


Research and care on the integration of blockchain networks with other services and apps.

2) Core Blockchain Developers

Core blockchain developers are responsible for the development and optimization of the architecture. The developer designs, develops and optimizes the protocols that support blockchain solutions. A good example is the Consensus Protocol which defines how the members using the blockchain and the resources agree to share and use these resources.

Core blockchain developers implement the functionality and features of the blockchain and ensure that they perform the intended functions.


- They design and implement the security of the network.


- They make sure the network is on.


- They plan, design and implement the integration of blockchain networks with other services.


- They plan to expand the features and functionality of a blockchain network.

Technical Skills Required for Blockchain Developers

First and foremost, you must have an academic background in Computer Science/ Information Technology field. You can choose to pursue a bachelor's or master's degree in a particular stream. While it is not mandatory to have a specific educational background to become a blockchain developer, it will help you understand the fundamentals and lay the foundation for learning blockchain technology effectively. Apart from degree programs, you can opt for several training programs to gain more experience in the particular technology.

Some of the key skills are as follows -

1) Understanding Blockchain Architecture

Be sure to understand what a blockchain is, such as advanced blockchain security, applications, and integration, and the advantages and limitations of blockchain and its challenges. Blockchain developers need to understand blockchain consensus, hash functions, and distributed ledger technology. The white paper defines the architecture and functioning of the blockchain. They need to understand the different blockchains and their functioning, the most important being Ethereum, Bitcoin, Neo and Hyperledger.

2) Data Structures and Databases

A developer must properly configure the blockchain network as per the requirement and therefore understand the various and thus the best database and data structures for the target network.

3) Smart Contract Development

A developer must understand the types of smart contracts and how to develop them.

4) Understanding Decentralization

As applied in blockchain and decentralized applications. These dApps can be built on different blockchain platforms using different protocols and processes.

5) Understanding Cryptography

Cryptography and digital ledgers form the basis of the functioning of the blockchain. The developer must understand what cryptography is, the algorithms applied in cryptography and which algorithms work best for what type of blockchain network. They should know how these algorithms are developed.

6) Understanding Cryptonomics

It is important to understand how cryptocurrencies are coded on the blockchain. Blockchain developer training and courses can teach game theory, the mathematical framework for modeling cryptonomics, and the difficulties involved in modeling. They should also understand what are the factors that influence cryptonomics and related monetary policies.

7) Computer Coding

Computer programming is essential to the development of any advanced and effective decentralized app or dApp, although in some cases you may be able to develop a beginner dApp without this skill.

Most blockchain developers start by learning programming language or coding and then use it to specialize in blockchain development. Most blockchain development requires programming or coding languages ​​of the mainstream, but some blockchains such as Aram require knowledge in a specific coding language on which they are based in order to develop anything.

The career of becoming a blockchain professional is not that easy, it requires a lot of dedication, hard work and consistency. But today with the rapid development of blockchain technology, the career scope of blockchain developers is becoming very bright and bright.
