How to become blockchain developer [Beginners Guide]

Written by - Deepak Prasad

The significance of blockchain in today's environment is being debated. However, its future position appears to be well-established, and there is little question that it will replace well-known solutions in a variety of fields. It works well now in areas where security and transparency are important. Blockchain is utilized in cryptocurrencies, financial systems, and IoT, among other things, and it totally alters the standards wherever it is used. Blockchain demonstrates that security, transparency, and decentralization can all coexist. And yet, until recently, Bitcoin was the sole embodiment of this concept. The potential influence of blockchain on our future may cause some alarm. It does, however, inspire you to be a part of this worldwide change.


What does a blockchain developer do?

We already know that blockchain is a future technology, so pursuing this specialty is worthwhile. So, let's take a look at what a blockchain developer performs and how it varies from the job of other programmers.

A blockchain developer, by definition, is someone who optimizes and constructs systems based on blockchain technology, such as smart contracts, dapps, or protocols.

A blockchain developer should be well-versed in several programming languages, the most important of which is likely to be the one closest to the developer's backend. The distinction, however, is in the assumptions behind blockchain and distributed ledger technologies.

  • Smart contract development
  • Development of Blockchain backends and interactive front-end projects for Dapps
  • Keeping an eye on the entire pile on which their Dappas are working
  • Protocol design for blockchains
  • Creating network consensus mechanisms and security patterns
  • Design of network architecture
  • Oversight of the entire network


Why is it worthwhile to learn about blockchain technology?

Blockchain has a lot to offer, and we're not just talking about businesses here; we're also talking about engineers who work with this technology. By focusing on this speciality, we may have everything we want in our programming jobs: ongoing development, a range of tasks, and decent pay.


What qualifications are required to work as a blockchain developer?

The following skills will qualify you for the post of blockchain developer:

  • Analytical skills are needed not only in blockchain, but in any role in the IT business.
  • Since blockchain technology is unchangeable and distributed across several servers, it necessitates accuracy and attention to detail while developing. Blockchain-based products frequently process large quantities of cryptocurrency, making them vulnerable to assaults, and software weaknesses result in massive losses.
  • English is also necessary for various professions in information technology firms. And that shouldn't come as a surprise, given that everything produced in this profession is written in English.
  • Knowledge of integration with cloud services or comprehension of front-end technology are examples of additional talents.
  • Above all, adaptability and quickness of learning. A month in crypto is equivalent to a year in another technology. New features in a blockchain are frequently launched before documentation is produced for them. If you are serious about developing a blockchain specialty, you should start now.


How to become a blockchain developer?

  • IT studies: Every blockchain programmer must begin by mastering the programming language of their choice. When you graduate from computer science, you already have a good basis. All that remains is to investigate blockchain knowledge, which is the next stage.
  • Develop an interest in blockchain: To get started, learn more about blockchain, smart contracts, and decentralized applications (dapps).Courses and training are available to help you systematize your knowledge and present the applications of this technology.There is always something going on with modern technology, so it is also worthwhile to keep up with new information, such as on Twitter.
  • Begin coding: Theoretical knowledge must be put into practice. How should it be done? For example, you may learn about security by playing Capture the Ether, in which you try to hack a smart contract. This expertise will undoubtedly benefit you during your interview for a career as a blockchain engineer!


What qualifications do you need to start as a blockchain developer?

  • A blockchain developer should have a thorough grasp of blockchain, its operations, and its architecture. Cryptographic hash functions, consensus, and distributed ledger technologies should all be familiar to you.
  • You must have an in-depth understanding and application awareness of data structures like Merkle trees, petricia trees, etc.
  • To create a secure and immutable system, the blockchain employs a variety of data types in conjunction with powerful encryption. Without an understanding of data structures, knowledge of blockchain can only be deemed inadequate.
  • Blockchain is a combination of data structures and advanced cryptography, so it goes without saying that a thorough grasp of cryptography is also essential to become a blockchain developer.
  • In addition to asynchronous cryptography, several cryptographic methods, such as hash functions like SHA256 and KECCAK256, are employed in the blockchain to produce digital signatures.
  • Smart contracts have grown in popularity due to Ethereum. Every blockchain is now attempting to include smart contract capabilities into its system so that business logic can be readily applied to the blockchain.
  • Developing websites is an important component of programming a blockchain. When a person starts a career as a blockchain developer in the sector, the majority of them work on the fundamental architecture of decentralized apps.
  • You should be familiar with the fundamentals of both front-end and back-end development, such as designing interactive GUIs for Dapps, API support, request processing, and so on.


Top programming languages to learn if you want to work in the blockchain industry

  • Solidity

Solidity is an object-oriented programming language similar to Java. The fact that the Ethereum blockchain is written in Solidity is what makes understanding Solidity so appealing to software developers. Solidity is the programming language used to create smart contracts on the Ethereum Virtual Machine (EVM). As a result, Solidity is a must-have for every Ethereum aficionado.

  • Java

Among programming languages, Java is the most stable. The language is extremely adaptable as well as an absolute standard in the blockchain field. In addition to the traditional development of back-end and front-end apps, software engineers may utilize Java to get started with blockchain.

  • Python

Python is quickly becoming the industry standard for data analysis tools. Python is no longer an option for anyone who envisions a career in quantitative data research. Such abilities are also in high demand in the blockchain industry. Anyone who can successfully construct useful data records from massive amounts of raw data, ranging from hash rate to transaction volume, provides huge competitive advantages for their own organization.

  • C++

C++ is a popular programming language among blockchain developers. It can be used to carry out a variety of operations linked to blockchain technology. It's a must-have tool for anybody looking to create blockchain apps.

  • Swift

While Bitcoin maximalists believe that Bitcoin is the killer app of blockchain technology, the less fundamentalist portion of the crypto community believes that it is smartphone applications in particular that will drive mainstream adoption. This necessitates the use of skilled developers who are both knowledgeable about DLT and have the technical expertise required to construct such applications.



A developer is someone who uses this technology to optimize and build systems. Analytical abilities are required not only in blockchain, but in any profession in the IT industry. If you are serious about building a blockchain specialization, you should begin right now. Every developer should be well-versed on the operations and design of the internet's backbone, known as blockchain. Blockchain developers should be proficient with both front-end and back-end programming basics.
