Unlocking the Secrets to Becoming a Successful Blockchain Developer

“Has the Internet changed our lives? Have mobile phones changed our lives? The blockchain is something that is transformative.” This statement by Brook Pierce, the renowned entrepreneur, succinctly captures the transformative power of blockchain. But what is blockchain? Blockchain is a cutting-edge database mechanism with a decentralized approach that has become increasingly popular in the tech industry. Now, even though many consider its enmeshment with cryptocurrency to be its shot to fame, the power of blockchain can be harnessed for a diverse range of objectives. 

In accordance with the global trend, the Indian tech sector also witnessed the growth of blockchain in the past few years. For instance, capped at a mere $0.28 billion in 2019, the market volume of blockchain is projected to reach $4.3 billion by the end of the next year, growing at an astonishing 47.3% CAGR. With this revolutionary surge, blockchain development has become a promising career path with exciting opportunities for tech professionals. If you envision your career as a blockchain developer, here is what you must know to advance in this career. 

What Skills are Required to Become a Successful Blockchain Developer?

Before going into the pragmatic question of what skills you require to become a blockchain developer, let us first understand what blockchain really is. The first time blockchain technology appeared, albeit in a nascent state, was in 1982. In his 1982 doctoral dissertation titled Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups, cryptographer David Lee Chaum first introduced the idea of a distributed computer system. This formed the backbone of blockchain technology. Later, blockchain technology was developed further by Stuart Haber and W. Scott Stornetta. It gained prominence with the launch of Bitcoin cryptocurrency in 2009, which showcased its potential as a form of distributed ledger technology (DLT). 

In essence, blockchain is a novel technology that allows for secure and unalterable transactions across a decentralized network. Beyond digital cryptocurrency, blockchain is now applied in various sectors, such as supply chain management, cybersecurity, healthcare, banking, and financial markets, to name a few. Moreover, in India, the government has been keenly interested in blockchain technology. For example, the Ministry of Electronics and Information Technology of the Indian government developed its National Strategy on Blockchain in 2021 with the stated objective of building a “vigilant and trusted collaborative digital ecosystem” to provide various e-governance services to citizens.

Now that we have briefly discussed the history of blockchain technology and illustrated its significance in both the public and private sectors, let’s look at what skills a blockchain developer needs.

1. Understand Distributed Ledger Technology

Blockchain technology allows tech professionals to build secure and immutable records.  Multiple stakeholders hold copies of the historical ledger within the framework of a decentralized network. Hence, a blockchain developer must not only master Distributed Ledger Technology (DLT) but also understand its application across different sectors.

2. Proficiency in Computer Languages

Success as a blockchain developer requires mastery of programming languages such as Java, C++, Solidity, and Python. Proficiency in these languages is essential since it enables the creation and maintenance of complex blockchain architectures and applications. It enhances interoperability within the tech industry.

3. Knowledge of Blockchain Architecture

 A blockchain developer must be skilled at understanding and working with diverse architectures—public, private, and consortium. Each of these architectures has specific use cases, such as enhancing security with private blockchains or fostering collaboration with consortium blockchains. 

4. Expertise in Cryptography

Blockchain systems enhance privacy within a digital network and ensure secure transactions. Blockchain developers often deploy cryptogenic techniques such as hashing and digital signatures to do this. As a result, it protects data from unauthorized access and ensures transaction integrity. Thus, one must be adept at cryptography to succeed as a blockchain developer. 

5. Development of Smart Contracts

Smart contracts are pivotal in automating enforcement in blockchain transactions. Hence, blockchain developers must be skilled in coding and deploying smart contracts that execute automatically under predefined conditions.

6. Knowledge of Data Structures

To build an effective blockchain, developers depend on complex data structures like linked lists, hash tables, and trees.  They play a prominent role in various applications. These include data management, enhancing the speed of transactions, and improving the scalability of blockchain applications. Therefore, success in the field of blockchain development necessitates a solid grasp of complex data structures.
