As enterprises dip their toes deeper into the business uses of blockchain, a new job market is forming around blockchain architecture, development, project management and sales. For many individuals, blockchain represents greener pastures that, if acted upon quickly, can provide lucrative and highly sought-after careers.
Yet many people interested in becoming blockchain professionals possess little or no experience in the field -- and aren't even sure where to start. That's why blockchain certifications are becoming more popular. Certifications have long been part of the business world and flourish in fields like information technology, project management, financial services and sales. So, it makes sense for those planning a career in blockchain to take relevant courses and receive a certificate of completion that represents an acquired skill set. These certifications can help blockchain career candidates stand out from the pack and are a great way to land a new role in a field that has tremendous growth potential.
What are the types of blockchain certification courses?
Roles within the blockchain field vary widely, but nearly every job requires at least a basic knowledge of blockchain technologies and how they can be used to benefit private and public organizations. Since blockchain is still a relatively new concept, virtually all courses and certifications start out with an introduction to blockchain and associated concepts and terms.
Some blockchain certification courses cover just the introductory level, while others provide more detailed information on how to design, program and secure the various parts of a blockchain system. In most cases, these certifications are geared toward developers and architects that require more in-depth technical information.
In addition, a handful of courses focus on a specific aspect of blockchain -- in the form of a specific programming language or developer specialization. These courses are best for those who already have a solid introductory blockchain foundation and want to increase their skills with a specific developer and architecture subset.
What are the benefits for blockchain certification holders?
Certifications typically prove some form of expertise in a field that interests the student and job candidate. Because blockchain skills are in such high demand, blockchain certification holders can benefit in many ways:
- higher salaries than comparable, non-blockchain roles;
- less competitive and shorter corporate ladder to climb;
- emerging opportunities in business verticals adopting blockchain technologies; and
- the potential to disrupt and envelop other business fields, further increasing demand for blockchain skills.
