Blockchain Developer: Understand What It Is

Blockchain Developer: Have you ever heard of blockchain? I bet, yes! Because it is something very new, many people have heard about it but do not always know what it is, but it is a disruptive technology that people are increasingly turning their eyes to.

And that’s precisely why the search for professional blockchain developers is growing. In general, the market needs more professionals, not only blockchain developers but professionals in public for the entire technology market.

What Is Blockchain?

Blockchain is a digital ledger (accounting book) storing and recording financial transaction information.

The direct translation of blockchain means a chain of blocks, where each block contains a set of data, and in every space of time, a new partnership is created and linked to the previous block, creating a sequential chain, which is why it is called a blockchain. In general, it consists of a database.

Another way to understand the blockchain is to think of a peer-to-peer (p2p) network; in this type of network, there is no central server that stores data but a conglomeration of user computers that are points or nodes that function by providing service—and sharing the data.

Advantages Of Blockchain

One of the great benefits of blockchain is that all the information it contains is encrypted, requiring a digital signature. In this way, it is possible to guarantee the security of transactions, increasing integrity and protection against threats.

As it is decentralized, any user can access transactions. However, they cannot be changed after they have been processed.

In addition, it is possible to access the blockchain from anywhere and allows the system to be distributed on numerous computers, making an update quickly create synchronized copies.

And this is precisely why it is increasingly vital for us to know more about blockchain. Undoubtedly, it is a technology that is here to stay! How about we learn in more detail now what a blockchain developer is?

What Is A Blockchain Developer?

The blockchain developer is the professional responsible for developing and optimizing the protocols contained in the blockchain. In addition, these people also work in developing smart contracts, dApps, marketplace, and other applications that the blockchain allows.

What Are The Roles Of A Blockchain Developer?

It is possible to find two types of blockchain developers within this technology area.

The first is the leading developer who seeks to design the security and architecture of the entire system, in addition to creating the base on which the software developer (this is the second) will use to develop decentralized applications (DAPPS) and web using the core architecture of the web, done by the lead developer.

In addition, both types work with designing, modeling, and developing three-dimensional models.

The same person can perform the functions of both the leading developer and the software developer, especially in smaller companies that do not have a defined structure.

Check out some of the main functions of a blockchain developer below:

  • Development of blockchain protocols;
  • Development of consensus protocols;
  • Front-end development of DAPPS;
  • Back-end development ;
  • Management and development of smart contracts.

How To Be A Blockchain Developer?

The first point to highlight is that higher education in  ​​technology is not required; higher education is not even needed. This happens due to the significant lack of professionals it has.

In addition, because it is something extremely new, many colleges still need specific disciplines to deal with this subject. And that’s precisely why the chances of employability are real.

Well, the first thing you should keep in mind to be a blockchain developer is to identify the most used programming languages ​​within the technology.

And to facilitate your research, we will present here the main programming languages ​​used in the blockchain for you to train yourself and conquer your space in the market.

We have already made it clear that these are languages ​​already known by most IT professionals. Let’s go.


Through Python, we can create prototypes and take advantage of broad open-source support and many libraries and plugins.


Java is a programming language that performs well with object orientation and has a large community of applications and partner platforms that are part of the ecosystem.


C++ has good memory management as well as object-oriented features.


This language has been experiencing significant growth within blockchain applications, as it can solve various problems through it.

It was created thinking mainly about the Ethereum network that owns the token ETH, the most famous blockchain platform.

Well, these are the main languages ​​you should know if you want to become a blockchain developer. Now it’s up to you to look for specific skills for the topic, so we have a gift for you!
