How to Become a Blockchain Developer | Must Have Skills

Blockchain technology is poised to revolutionize the way the digital world handles data and does business. Initially created as a platform for supporting Bitcoin, Blockchain is demonstrating a level of versatility and security that has made many sectors of business and government take notice and begin putting it to their use.

With that in mind, it makes sense that if you want to jump into a career that has a lot of potential for growth, featuring a dynamic new technology that’s just getting started, then you should consider becoming a Blockchain developer.

If this prospect intrigues you, and you want to know how to become a Blockchain developer, then read on and find out all you need to know about this exciting and intriguing profession.

What Is a Blockchain?

A blockchain is a digital ledger of all cryptocurrency transactions across all peer-to-peer networks. And this blockchain technology is different from any other traditional transactional methods which are centralized and controlled by certain governments and groups. But this blockchain is a decentralized one, which means that this is not subject to the control of any single entity or group.

This technology benefits more businesses around the world because blockchain technology allows businesses to conduct secure transactions without involving third parties. Network nodes verify transactions and record them in a publicly dispersed ledger called a blockchain. Each node in the network updates and preserves the blockchain continuously. That's why Blockchain technology is especially known for its security, as it is very difficult to tamper with data once it has been recorded on the blockchain. Furthermore, the cryptographic hash makes it nearly impossible to alter data without it being detected.

What Is Blockchain Development?

Blockchain development is the process of developing and maintaining a blockchain platform. This involves creating the infrastructure that allows for the creation and management of blockchain-based applications and services, such as digital currencies, smart contracts, and distributed applications. It also involves developing the tools and technologies needed to support the platform.

A blockchain application is simply a program or platform that uses the features and benefits of a blockchain, such as security, transparency, and reliability. Blockchain development is a complex process that requires a deep understanding of the underlying technology. It also requires a firm commitment to security and scalability. Developing a blockchain platform is a major undertaking that requires significant resources and expertise.

What Does a Blockchain Developer Do?

A blockchain developer develops decentralized applications (dApps) and smart contracts based on blockchain technology, as well as understanding the architecture and protocols of the technology. They are responsible for developing 3D models, 3D designs, and 3D content such as that used in games.

The wise yet short answer to this is: a Blockchain developer develops Blockchains! Well, that was easy!

Now that we got that out of our system let’s take a serious look at what a Blockchain developer does. To best answer this question, we first need to establish that there are two different types of Blockchain developers; there’s the Core Blockchain Developer and the Blockchain Software Developer. Call them sub-divisions of Blockchain development.

Also Read: Why is Blockchain Important and Why Does it Matters?

A Core Blockchain Developer designs the security and the architecture of the proposed Blockchain system. In essence, the Core Blockchain Developer creates the foundation upon which others will then build upon.

What “others” are we referring to? That would be the Blockchain Software Developers, of course, who use the core web architecture built by the Developer to create apps, specifically the decentralized (dapps) and web varieties.

Perhaps there may be situations where the same person fulfills both roles, most likely in cases where the business is small, and people traditionally wear more than one hat. Whatever the case, the everyday responsibilities and roles of the Blockchain developer are: 

  • Design the Blockchain protocols
  • Design the network architecture that can be used for the centralizing or decentralizing the data
  • Backend development according to the Blockchain protocols
  • Developing front-end designs according to client requirements
  • Developing and monitoring any smart contracts

The Blockchain developer’s responsibility is to develop innovative solutions to challenging problems, including solutions for command and control, and high integrity. The developer also performs complex analysis, design, development, testing, and computer software debugging, specifically for distinct product hardware or for technical service lines of businesses. Develops perform software design, operating architecture integration, and computer system selection. Finally, they operate on multiple systems and apply knowledge of one or more platforms and programming languages.

Of course, obstacles are awaiting the Blockchain developer. For instance, the developer has to work with legacy infrastructure and its limitations, while still meeting the expectations inherent in a Blockchain development project. Also, there are the challenges of understanding the technical practicality of implementing decentralized cryptosystems, processes that fall outside of the traditional IT development skill-set, which means a Blockchain developer needs specialized skills.

How Does One Become a Blockchain Developer?

So, after all of that, the questions present itself: with all of these responsibilities, how does one train someone with the necessary skills to let them rise to the challenge of Blockchain development? There are two different situations at work here. There are the Blockchain hopefuls who are starting completely from scratch, having no background in programming whatsoever, and those who have experience in careers that share similarities with Blockchain.

Best Blockchain Programming Languages 

There are several popular blockchain programming languages, like,

  • Solidity on Ethereum, 
  • Python on Bitcoin Cash, 
  • and Java on the NEO platform,
  • C++.

 But choosing the best language will be difficult.

  • If you're new to blockchain technology or programming, consider learning one of the more popular languages, such as Solidity or Ethereum. These languages are general purpose and make it easy to develop decentralized applications (dApps) on top of the blockchain. They also have built-in support for smart contracts and other features that can help increase security and efficiency when building dApps. 
  • However, suppose you're already familiar with some aspects of blockchain technology and want to build custom applications rather than pre-made templates, then consider languages like Java or Python, which allow developers to create traditional desktop apps using coded instructions rather than just coding in code blocks. 

Ultimately, picking the correct language depends on your specific needs and preferences. Just be sure to research each one thoroughly before making a decision!

Advantages of Implementing Blockchain Solutions

There are several advantages to implementing blockchain solutions in your business. Here is a summary: 

  1. Transparency and security: Blockchain technology provides transparency and security for both the sender and the receiver of data. Transactions are verified by multiple nodes, which eliminates the possibility of fraud or mistakes. In addition, because all information is recorded on a public ledger, it becomes challenging to tamper with data once it has been uploaded. 
  2. Ease of use: Blockchain technology can be used with highly automated systems, making them easy to operate and manage. Because transactions are processed directly between users without any third-party involvement, there is little need for reconciliation or validation procedures. For example, when two people sell goods to each other using Bitcoin, they don't need to go through an intermediary (such as PayPal) to complete the transaction. 
  3. Reduced processing time: Because blockchains are decentralized networks that run on distributed computers worldwide, they can process transactions quickly and efficiently – usually much faster than traditional payment systems like Visa or Mastercard. This speed advantage can be significant in situations where time is critical (e.g., financial transactions), medical records management, legal contracts, etc."
  4. Greater Efficiency and Speed: A well-designed blockchain system will allow you to process transactions faster than traditional systems because it is tamper-proof and requires less processing power, making it ideal for businesses that need to operate quickly to keep up with the competition.
  5. Enhanced Customer Loyalty and Brand Reputation: A good blockchain solution can increase customer loyalty and build a brand reputation internationally, far beyond what traditional marketing approaches could achieve alone!

What Kind of Mindset Do You Need to Become a Blockchain Developer?

Before we dive into those two different types of people aspiring to become Blockchain developers, it may help to familiarize ourselves with the kind of mindsets that are best suited for Blockchain developers. After all, the unique challenges of Blockchain development require a certain unique way of thinking.

Whenever you hear the word “hacker” spoken aloud, it’s not usually in a positive light; no self-respecting business wants anything to do with hackers (well, except for ethical hackers, but that’s a different story for a different time). However, it’s precisely the hacker mentality that helps make good Blockchain developers. That’s because hackers tend to think outside the box when faced with problems and obstacles, rather than engage in conventional thinking.

Furthermore, a good Blockchain developer works well with a team and can collaborate. On a related point, the ideal Blockchain developer knows when to ask for help with a problem and when to keep plugging away by themselves until they arrive at the answer.

So the best candidate for Blockchain development works well with others, knows his or her limitations, and can unconventionally approach problems.
