Blockchain is a revolutionary technology that has created vast job openings for tech developers around the world. This technology can be used by numerous industries for a countless variety of applications, including secure money transfers and supply chain monitoring. Those who learn blockchain’s structural design—blockchain developers—can also develop and optimize its protocols. 

There are two types of blockchain developers:

  • Core blockchain developers do the primary work involving blockchain design, its protocols, and the technology used.
  • Blockchain software developers create various blockchain applications using the configuration done by core blockchain developers. 

As blockchain technology continues to gain ground, both for its convenience (shared ledgers) and security (cryptocurrencies, for example), it’s not surprising that an increasing number of businesses and organizations are taking notice. This has created fertile ground for a new generation of tech professionals to make their marks. 

Online certifications such as Simplilearn’s Blockchain Certification Training Course will help enhance your skills to become a proficient blockchain developer, with a certificate to show prospective employers or clients. You don’t have to be a professional to take the course, but it’s good to have a fundamental knowledge of distributed systems, Object-Oriented Programming (OOP) concepts, flat and relational databases, and centralized networks so that you can better understand the backend architecture.

You can use any available platform such as Ethereum or Hyper Ledger to start coding. With practice, you can enrich your development skills and build blockchain applications and tools.

What Exactly is Blockchain?  

Let’s put aside blockchain’s broader applications for a moment and address a critical point: what is blockchain, anyway? Blockchain is a newly developed, decentralized, distributed transaction system. It is a means of both securely and transparently storing online records of transactions. Individuals’ records are known as blocks, which are in turn linked together into chains.  The operation is accomplished by means of a peer-to-peer network system. 

All of the participating users’ computers work together to verify the records and then add them to the blockchain. As the block creation is a sequential process, no single computer can add any block to this chain. With the help of cryptography, a new block is attached to the blockchain. The records of the block are kept permanently, and the chain continues without any break, which prevents the chance of any misconduct or erroneous transaction. 

If you use Google’s popular Docs or Sheets applications, you know that everyone who has access to the files can see changes almost immediately; it’s transparent but also secure. This is similar in concept to blockchain technology.  

Blockchains came into existence because of loopholes in the banking sector. It is a new way of transferring funds or information without involving a third party, invented by someone known only by the alias “Satoshi Nakamoto” initially to serve Bitcoin as a mode of cryptocurrency. Since transactions don’t take several days to be completed, even for intercountry transfer, blockchain is ideally suited for currencies.

Potential Blockchain Applications  

Public blockchain applications could someday make our lives easier and more secure. Here are a few current and promising applications for blockchain:

  1. Settlement of Payments and Money

    With the help of blockchain, money can be easily and transferred—typically within seconds—without much inconvenience. 
  2. Keeping an Eye on The Supply Chain System

    Using blockchain, we can scrutinize the supply chain system competently not only for the sake of the business but also for the consumers’ convenience. 
  3. Retail Loyalty Plans

    The retail sector uses loyalty reward programs to connect with customers and strengthen ties with merchants. Using blockchain, stores could maintain records to form a reward-based program for the consumers by means of tokens. 
  4. Royalty and Copyright Security

    With the help of blockchain, the reallocation and transfer times of digital assets could be noted and logged. Copyrights could be purchased legitimately and content owners would get their rightful share.
  5. Digital Voting Systems

    With blockchain, votes could be cast digitally and securely preserved. If any fraud is being perpetrated, the regulators could pinpoint the error because of its distributed network presence. 
  6. Data Backup 

    Though cloud storage devices are available for data backup, they’re vulnerable to hacking. Properly implemented, blockchain technology could negate the possibility of a data breach.
  7. Equity Trade 

    The current process of equity trading is time-consuming. Blockchain technology’s speed in performing transactions such as completions and confirmations can potentially reduce or even eliminate wait times.
  8. Medical Records 

    Digital storage has given rise to concerns about the disclosure of confidential patient records. Blockchain technology offers data protection with easy access.
  9. Tracking Weapons 

    A registry network can be created using blockchain to record weapon details, which a government could then access in order to track a weapon’s owner or to whom it was sold.
  10. Ownership Transfer

    When selling assets such as land and buildings, all of the pertinent details could be registered and saved in electronic form via blockchain. Even past details could be gathered and retroactively entered into the blockchain database.

Career Scope and Opportunities in Blockchain

Becoming a developer and enrolling in blockchain programs is not the only career option available in the blockchain family. Though it is one of the trendiest career choices in 2019, there are many more options (and courses to help prepare for them) for graduates and computer IT folks in the blockchain field. Having blockchain training and appropriate certification will help open up more doors.

Here are some of the most promising career choices available:

  1. Project Manager

    The role of a project manager is to act as a mediator between business professionals and application developers. For this role, you should have strong communication skills and more detailed knowledge about the blockchain system, as you’d have to deal with both technical and non-technical people.
  2. Quality Engineer 

    The quality engineer has to test various software modules within the environment of the blockchain by working with different network speeds, testing tools, platforms, and frameworks. To apply for this position, you should have a clear knowledge of the full blockchain architecture and the testing principles of the engineering world. 
  3. Web Designer

    As we are on the verge of harnessing blockchain capabilities with cryptocurrencies, there is an increased demand for web designers. In this role, you would create user-friendly web portals to interact with backend databases. Having a thorough knowledge of HTML, CSS, Javascript, and other scripting languages would be a major advantage.
  4. Legal Consultant

    These professionals basically act as bridges, providing advice to business firms to build methodology via legal divisions, such as how to go for an Initial Coin Offering (ICO) or leverage transactions efficiently. You should have a law degree for proficient legal discussions, along with the appropriate technological knowledge.
  5. Application Developer

    This is undoubtedly the highest-paid blockchain profession, where you’re required to develop the necessary applications via software and programming languages. For this role, you should have a sound knowledge of Ethereum smart contracts using Solidity language, Hyper Ledger along with C, C++, and jQuery, among other technologies and platforms.
  6. Interns

    This is an entry-level position that offers great opportunities for learning and understanding the blockchain process flow. Starting out as an intern can help you determine the best career route to take as you gain more knowledge and experience.
