08 July 2020 07:52, UTC
Blockchain appeared as a revolutionary technology that changed the world of online payments and introduced new standards of online security. Experts from many industries have quickly noticed the opportunities blockchain gives so this technology started to develop at a rapid pace. The popularity of blockchain is a reason why blockchain developers are in great demand.
However, if you want to become a blockchain developer, you may feel confused about where to start and in what direction you should move. Therefore, we decided to help you with this article so that you can know the main benefits and challenges of becoming a blockchain developer.
Being a Blockchain Developer: The Main AdvantagesBlockchain developers create and optimize blockchain protocols. There are two major types of blockchain developers: core developers and software developers. Core developers work on the architecture of a blockchain system. They design blockchain protocols, consensus protocols, and overall architecture. Core developers are also responsible for the security of a blockchain system.
Software developers have different roles because they don’t work with the architecture and the consensus design. Most blockchain software developers create decentralized applications (dApps) using the design structure that was created by core developers. Software developers also work on smart contracts.
No matter whether you decide to be a core developer or a software developer, choosing blockchain as a profession offers you a number of benefits. Here are some of the main advantages of becoming a blockchain developer.
- High salary
- Trendy specialty
For instance, as the Internet of Things becomes more and more popular, companies from this niche are also actively adopting blockchain. Given that security is one of the main concerns when it comes to IoT devices, blockchain becomes one of the most promising solutions.
- Huge demand on the market
- It is challenging but interesting
- You can teach others
You may be a partial owner of a cryptocurrency if you are lucky enough to work in a promising startup
Many blockchain startups have their own cryptocurrencies, and if you become a part of a blockchain team at the very beginning, you can also get an opportunity to become a successful cryptocurrency investor or a partial owner.
- You may contribute to other trending technologies that are used with blockchain
How to Become a Blockchain Developer?Although getting a formal education may not be the fastest way to learn blockchain development, it doesn’t mean that you shouldn’t consider such an option. Some universities offer courses related to blockchain development. For example, there is a Bitcoin and Cryptocurrency Technologies online course from Princeton, as well as various courses offered by Blockchain at Berkeley — an off-campus organization created by students.
However, you should be ready for the fact that you will have to learn a lot by yourself. As we’ve already mentioned above, blockchain developers should possess different skills and be familiar with different areas, including cryptography, front-end, and back-end development. Fortunately, there are many useful materials on the internet, including tutorials and tools that can help you not only learn the theory of blockchain but also use your knowledge in practice.
First, you should learn the basics of blockchain programming and cryptography. You should understand what decentralization is, the difference between public and private types of blockchain, as well as the specifics of the decision-making, and different types of consensus. We recommend that you familiarize yourself with popular decentralized applications and Blockchain as a Service (BaaS) solutions, like Ethereum Enterprise, Hyperledger, etc.
Even though blockchain now has numerous applications, we recommend that you don’t forget about cryptocurrencies, which still remain the most common use case of blockchain. For example, you may benefit from checking out different crypto exchanges. There’s no need to invest or trade cryptocurrencies, you just have to understand how cryptocurrencies work.
Once you’ve familiarized yourself with blockchain, you can start to create your own blockchain-based applications. For example, you can learn Solidity — an object-oriented language that is used to create smart contracts on the Ethereum blockchain. There are also many blockchain platforms and applications that are based on the open-source code so you can easily access and study it.
Creating a blockchain is not an easy process, and it requires you to address a number of issues, including resource management, security isolation, and performance. To build your own blockchain, you should follow these six steps:
- Create a simple block;
- Use it to make a blockchain;
- Figure out what a genesis block is, and implement it;
- Add new blocks to your blockchain;
- Validate the entire chain;
- Do a test run.
Why It Is Difficult to Be a Blockchain DeveloperFirst of all, becoming a blockchain developer is difficult because you have to learn a lot and to master completely different skills. While software developers only need to write code, blockchain developers have to deal with a variety of different tasks, including resource management and security. Besides, developing distributed applications is challenging by itself.
“It’s hard to develop and test software that runs on one computer, and it’s even harder to create software that involves a network of computers,”explains Ann Patterson, a front-end developer at Pick The Writer. For instance, the way computers operate is a reason why the developers have the term “heisenbug.” Such bugs change their behavior when you try to test them. When developing decentralized applications you may deal with heisenbugs quite often.
The development of distributed applications is also associated with another type of bug, which is called “mandlebug.” Such bugs are so complex that when you observe them, they seem like complete chaos. Such causes are too obscure, and fixing these bugs can take a lot of time. However, mandlebugs are not the only weird challenge associated with blockchain development. You may also experience so-called “schrödinbugs.”
“Just like Schrodinger’s cat that isn’t dead nor alive until you open the box, these bugs also remain unnoticeable until the end-user starts to use the application,”explains Jack Owen from Writing Judge.
It’s important to mention that these types of bugs are not blockchain-specific. You can deal with such bugs when developing non-distributed software, as well. However, they become an even bigger problem when creating decentralized applications. Therefore, testing, developing, and supporting such applications becomes an even more difficult and expensive task.
How Fast The Cryptocurrency Trend Will DevelopAlthough cryptocurrencies appeared not so long ago, they have already made a significant impact on different areas of business and introduced new ways of funding and investment. In late 2017, cryptocurrencies were one of the most discussed topics. After the cost of Bitcoin reached $20,000, more and more people started to invest in cryptocurrencies and to learn blockchain development.
The main feature of cryptocurrencies that made them so popular is security. Advanced encryption and the decentralized nature of cryptocurrencies make them the safest tool for online payments. Blockchain is self-regulated and absolutely independent. There is no third party that could access your sensitive information, steal, or change it. At the same time, cryptocurrency transactions are completely transparent so that everyone can check records without being able to access personal information.
Cryptocurrencies also created many investment opportunities, which is another reason why cryptocurrency projects became so popular and started to grow so quickly. On the one hand, the cryptocurrency market is extremely volatile. On the other hand, if you understand its underlying principles, you can invest in cryptocurrency startups and make cryptocurrency trading your source of income. Besides, the volatility issues may not be so serious in the future, given that the cryptocurrency market is being more regulated now.
Now let’s take a look at the current trends in the blockchain world.
- Less hype
- Less scam
- More trust
- More adoption
- Blockchain plus IoT
- Blockchain plus ML and AI
- More blockchain startups (and more failures)
- National cryptocurrencies
- High demand for blockchain specialists
Final ThoughtsBlockchain and cryptocurrencies are no longer just buzzwords. Blockchain is already used in different industries, and cryptocurrencies are getting recognition from official institutions. Some countries already have or develop their own cryptocurrencies, and it makes sense to expect even more countries to do the same in the nearest future.
Given that blockchain allows individuals and companies to store data of any kind, it can help us address many security issues, including identity theft. If you store your personal information in a blockchain, nobody will be able to change it. Blockchain also offers countless opportunities for trade because it not only enables easy and secure payments but also helps eliminate third parties and increase transparency thanks to self-executing smart contracts.
Given that cryptocurrency transactions are completely transparent, blockchain can also help fight corruption, which is an especially important issue for developing countries. The advantages of blockchain are hard to overestimate so if you want to become a blockchain developer, you’ll get numerous career opportunities.
Even though learning blockchain is a time-consuming and difficult task, the result certainly won’t disappoint you. Blockchain developers are advanced people in the IT industry, and they are in great demand.
