In our last article, we created a basis for the blockchain topic and explained the basics in more detail. In general, the topic is very much on the rise and we at ElevateX are also dealing with the topic. Thus, there is also an extra section on Blockchain and Web 3.0 in our blog. Especially, blockchain developers who are experienced in this area are currently in high demand.
In this article, you will find some tips to get started as a developer on the topic of blockchain.
What Is a Blockchain Developer?
Blockchain developers design, implement and test blockchains as well as blockchain-based solutions or applications. As the blockchain field is currently enjoying high demand, many industries are looking for suitable experts. Therefore, blockchain developers can be found in many IT departments of almost all economic sectors.
Especially in the financial industry, e.g., at banks, it is evident how important the topic of blockchain is and how high the demand for suitable developers is. In the area of finance, blockchain solutions are particularly suitable. Therefore, banks aim for solutions in this area to gain competitive advantages.
According to the German Federal Employment Agency, a degree in, for example, computer science or business information systems is usually required. A completed relevant training or further education can also provide access to the job. In addition, there is the possibility to become a “Certified Blockchain Developer” via courses and exams. Courses for this are offered by Blockchain Council. Blockchain developers work as permanent employees and as freelancers as well.
What Does a Blockchain Developer Do?
Blockchain developers develop ways to represent, document, and control business processes, coordination processes, or financial transactions using a blockchain solution.
Blockchain developers are responsible for designing and customizing blockchain-based solutions. This includes, for example, the introduction of smart contracts in companies or public authorities.
Blockchain development includes a lot of creative work. Since many areas do not have a precedent for using the blockchain yet, testing and creative work needs to be done.
Another important part of a blockchain developer’s job is connecting the blockchain solution with non-blockchain solutions. Blockchain developers define data structures and develop the interfaces to other components and systems. This is of great importance, as only in this way all systems can run smoothly, communicate with each other, and the Blockchain have a great benefit.
If the interaction of different systems does not work in final tests, the developers have to go troubleshooting and find solutions for this. Since the technology is still in its infancy, a lot of creative work and testing is necessary as well.
Top Skills to Become a Blockchain Developer
To become a successful blockchain developer, a broad range of competencies and skills is fundamental. These include core competencies such as agile project management, which are important in development. In addition, there is knowledge of database development, data encryption (cryptography), programming languages, and software testing.
Top 5 Programming Languages in Blockchain Development:
C++ enables efficient and low-level programming, which is also the strength of the programming language. In contrast to the programming language C, C++ is supplemented by a standard library, which brings further important functionalities. Despite much criticism regarding resources, incomplete object orientation, and others, the programming language is also used in blockchain development, in addition to system programming and application programming.
Python is considered a relatively popular programming language. This is because Python is quite easy to learn. On the one hand, there are only a few keywords in Python, and on the other hand, the structure is significantly reduced. This contributes to better clarity. These advantages make Python particularly interesting for game development or interactive user interfaces. Google and YouTube, for example, are also partly based on Python. Python is also important for the blockchain.
Rust was developed to be very practical and secure. Especially program errors, which can lead to security gaps, should be avoided here. Especially these advantages and already successful application areas, such as the Mozilla Firefox browser, make Rust an important programming language for the blockchain.

How to Become a Bockchain Developer?
Since the topic of blockchain is still relatively young but offers a lot of potentials, blockchain developers are in high demand. The topic will continue to grow in the future. Therefore, it is advisable to familiarize yourself with it as early as possible to gain extensive knowledge.
Step 1: The Basics
As already mentioned, you should have the appropriate academic background. This is not necessarily a requirement to become a blockchain developer, but it helps to understand the basics and also ensures a better project acquisition. Continuing education courses can also help to stay up to date.
Step 2: The Technical Requirements
Basic technical skills are important for development in the area of blockchain. This means:
- Master the programming languages already mentioned
- Understand data structures
- Knowledge of networking and databases
- Web design and development
Step 3: The Basics of Blockchain
Step 4: Cryptocurrency
An important application area for the blockchain is cryptocurrencies. Bitcoin, Ethereum, Sol, and many more. Due to the high security of the technology, such cryptocurrencies are particularly valuable, and it is important to understand the mechanisms behind them to get a full picture of the blockchain. Thus, one Bitcoin is worth over €40,000 at the moment.
Step 5: Decentralized Networks and Smart Contracts
Smart contracts are based on decentralized networks. A well-known example of decentralized networks is Ethereum and the resulting cryptocurrency Ether. Probably the most important programming language for this is the already mentioned programming language Solidity.
Step 6: Practical Experience
Now that the theoretical basics are in place, it is important to look for practical cases. Through practice and practical application, knowledge increases and better experience ensures more projects.
What Are Types of Blockchain Developers?
Rust is an open-source system programming language that focuses on speed, memory safety, and parallelism. Developers use Rust to create a wide range of new software applications, such as game engines, operating systems, file systems, browser components, and virtual reality simulation engines. Rust is also used in the development of blockchain solutions.
Selenium is an open-source tool for web browser automation. It provides an interface to write test scripts in programming languages such as Ruby, Java, NodeJS, PHP, Perl, Python, and C#.
Ethereum is based on blockchain technology and is therefore also an open-source, decentralized system. Ethereum offers the creation, management, and execution of smart contracts. Payments are based on its own cryptocurrency, which is called Ether.
Solana is based on a similar principle to Ethereum. The blockchain project also interacts with smart contracts. Only a different cryptocurrency is used. In Solana, this is called SOL.
Blockchain developers can be found both in permanent positions and on a freelance basis. The last one, in particular, is gaining popularity among developers in the blockchain field, among others.

What is the Salary of a Blockchain Developer?
Blockchain developers are among the highest-paid developers in IT – this is unlikely to change much in the coming years. Both permanent employment and using the services of a freelancer are currently very difficult.
Blockchain, and thus experts in the field, enjoy high demand. In the U.S., where the use of blockchain is already more established, developers earn on average between $125,000 and $175,000 per year, according to Talent – by comparison, the average salary of a software engineer there is $140,000 per year.
In Europe, where blockchain is just gaining momentum, salaries average between $55,000 and $91,000, according to cryptocurrencyjobs.
How Can I Implement Blockchain in My Own Company?
As already explained in the Beginner’s Guide to Blockchain, blockchain technology is considered to be particularly secure. As a result, it offers many possible applications in process handling or in the area of finance.
An important topic here, for example, are so-called smart contracts. These are automated contracts that make payments automatically as soon as a contracting party has fulfilled its obligation. As a relatively young technology with great potential, the blockchain also offers protection against technical problems and security.
