A Blockchain Developer | Its Types And The Roles

blockchain developer

Cryptocurrency, a fancy term probably unheard of to the old generation. The young generation, they know very well what it is. Yet, there is another mysterious term known as Blockchain. The term may be opaque at first but once people understand what cryptocurrency is then they will understand what Blockchain is.

In simple terms, blockchain is sort of a digital lender of transactions. It is different from the traditional ledgers used for centuries recording, sales, purchases, acquisitions, and other transactions. The function of blockchain is that it works like a typical one and records debits and credits between individuals and entities.

The difference is between the one who holds the ledger and the one who verifies the transactions.

What do we mean by the term blockchain developer and how to become one?

Within the past few years, numerous professionals have often been asked what a blockchain developer is and what kind of job do they do? In all honesty, it is easy to get confused but now is the time to clear that confusion.

A blockchain developer is one who is responsible for the development and optimization of blockchain protocols, creating the architecture of blockchain systems, developing smart contracts and web apps through blockchain technology.

The types of blockchain developers present

Any developer involved in developing Blockchain technology can be known as a blockchain developer. Now blockchain developers can be classified into two distinct types which are:

  • Core Blockchain Developers.
  • Blockchain Software Developers.

Core blockchain developers are often responsible for creating the architecture of a blockchain system. They also work on how its protocols should be designed, how the consensus protocol should be designed, and other high-level decisions and development related to this beautiful tech.

Blockchain software developers use architecture and protocols designed by Core Blockchain developers in making decentralized applications that are running on blockchain technology.

Roles of a Blockchain Developer

Now that we all have understood briefly the kind of blockchain developers around, we will now explore their respective roles in the lucrative and evolving industry.

Core Blockchain Developer

Such a developer is mostly involved in the design, architecture, and security of a blockchain system. In brief, their roles include the following:

  • Designing blockchain protocols.
  • Supervision of the entire network.
  • Design of the network architecture.
  • Creating consensus protocols and security patterns for the network.

Blockchain Software Developer

Blockchain software developers have different roles when compared to the former. These roles have nothing much to do with consensus design or the system’s architecture. Much like how a normal web developer uses the protocols and design structure set up by a core web architect in making web apps, blockchain software developers create decentralized applications (DAPPS) using blockchain technology.

The role of a blockchain software developer is as under:

  • Development of Smart Contracts.
  • Backend development pertaining to Blockchain.
  • Developing interactive front-end designs for DAPPS.
  • Management of the whole stack running their DAPPS.

Skills needed to become a Blockchain Developer

Now let us have a look at the technical skills needed for becoming a Blockchain developer:

Blockchain Architecture

Each blockchain developer should have a top-notch understanding of blockchain, its functions, and its architecture. The following concepts should be at their fingertips:

  • Cryptographic hash functions.
  • Consensus.
  • Distributed ledger technology.

Aspiring developers should once read the bitcoin blockchain whitepaper with guidance so they can raise their learning curve.

Data Structures

Those who wish to become a blockchain developer should have in-depth knowledge and applicative sense of data structures as it is compulsory. Blockchain developers are regularly modifying and tweaking existing data structures like Merkle trees, Patricia trees, etc. to meet personal network requirements.


Blockchain is a conjunction of data structures and advanced cryptography, hence it is only obvious that a really good grasp on cryptography is also needed to become a blockchain developer. A lot of cryptographic methods like hash functions are used in it apart from asynchronous cryptography for generating digital signatures.

Without understanding how these things work, no one can become a blockchain developer.

Smart Contract Development

Ever since the release of Ethereum, smart contracts are the new big thing. With every blockchain incorporating them in their functionality and system to apply business logic on Blockchain, developers are now learning more about smart contract development when desiring to work (and working in) blockchain.

Web development

It is a core aspect of a Blockchain developer. A lot of blockchain developers are first employed for working on the basic designing of decentralized applications. Once they understand the basics of front-end and back-end works, they can then go for creating interactive graphical user interfaces for DAPPS, API handling, handling requests, and the like.
