What Is Blockchain Development?

Blockchain is a unique type of database that stores information in "blocks" of data chained together in chronological order. Any new data gets written into a block, and when it is filled up, it gets timestamped and attached to the latest block in the chain, hence the clever name "blockchain."

So, the process of blockchain development is the process of creating blockchains.

What Is a Blockchain Developer?

Blockchain developers are professionals who develop applications for blockchain protocol architecture. Their daily tasks include developing and optimizing algorithms that run on the Blockchain Protocol. This protocol is piggybacked onto the standard Internet Protocol (IP), functioning as an Internet for blockchain-powered devices. This blockchain Internet is referred to as Web3.

What Does a Blockchain Developer Do?

Blockchain developers have a wide range of responsibilities and roles. For instance, blockchain developers write smart contracts, programs developed especially for the blockchain and run on blockchain nodes.

Blockchain developers create applications that conform to the Web3 decentralized protocols mentioned above. However, there are two significant branches of blockchain development.

  • Core blockchain development: This process involves interacting with blockchain at the root level. Core blockchain developers are responsible for designing and developing blockchain architecture, including choosing system protocols, consensus mechanisms, and other variables.
  • Blockchain software development: This role involves incorporating algorithms developed by other blockchain developers into the actual blockchain applications.

Blockchain Developer Job Description

So, let’s take the information we just discussed and see if we can put it into a convenient job description reference format.

In general terms, organizations looking for blockchain developers want professionals who can design, implement, and distribute applications that conform to the blockchain protocols and are secure. In addition, these companies expect their blockchain developers to analyze the organization's needs and accordingly leverage and customize existing blockchain technologies to deliver significantly optimized blockchain solutions.

But when discussing job description specifics, we need to differentiate between three different experience levels.

  • Junior Blockchain Developer

  • Document all development processes
  • Maintain both client-side and server-side applications
  • Implement application tests and continuous integration

  • Intermediate Blockchain Developer

  • Collaborate with the teams to help develop and deliver blockchain solutions
  • Optimize blockchain solutions and secure them using various cryptographic techniques
  • Write test-driven application source codes and implement interfaces and features using available developer tools and programming languages.

  • Senior Blockchain Developer

  • Collaborate with management and stakeholders to ascertain and outline blockchain-related needs
  • Deliver highly optimized blockchain applications and solutions using either established technologies or creating innovations
  • Lead the teams that design, research, and develop blockchain application technologies

The Blockchain Developer Roadmap

Roadmaps help you get to your destination quicker and help you avoid wrong turns and pitfalls. This blockchain developer roadmap enables you to take the right path to become a blockchain developer without making costly mistakes or false starts.

  • Learn the basics of programming: Blockchain development is under the computer science umbrella, so you must learn programming basics. First, learn a programming language like C++, Java, or Python, and follow it up by learning all about data structures and algorithms.
  • Familiarize yourself with blockchain architecture and cryptography: These two concepts are the blockchain’s bedrock.
  • Try out a few blockchain functions: Now you must learn how to use the programming languages and tools associated with blockchain app development. This step is where you get hands-on practical experience as a developer, creating consensus algorithms and smart contracts.
  • Master decentralized applications: Decentralization is one of the most valuable features of both blockchain and cryptocurrency. This concept removes control and decision-making from a centralized asset (a group, business, organization, or even individual) and gives it to a distributed network. Consequently, it would be best if you nailed down this aspect of blockchain programming, choosing either mobile app development or web development.
  • Get certified: Certification helps you enhance your blockchain developer skillset and makes you a more desirable choice for a company. Consider taking one or more online courses or attending continuing education classes to gain certification in related fields.

Once you have met these criteria, you’re ready to call yourself a blockchain developer. Congratulations!

Besides, if few people are doing it, that only makes your skills more in demand and potentially can lead to better positions and compensation!

3. How do I make money as a blockchain developer?

You can do freelance work, get hired by a company and make a consistent salary, or become a consultant.

4. Is blockchain open source?

Mostly, yes. Blockchain is a database, which isn’t typically something you can monetize. Additionally, most blockchain dapps are open source. However, some enterprise-level versions of blockchain dapps and other resources will have a price tag.

5. One of blockchain’s biggest draws is its supposed security. Is it really that secure?

While there's no such thing as a perfect system, blockchain is highly secure and thus will be in demand because of three primary reasons:

  • Blockchain is decentralized, so its database doesn’t have a single entry point
  • All blockchain transactions are transparent and traceable back to the users
  • Blockchain information can’t be changed once its recorded; user credentials are canceled if any data is altered
