Blockchain Developer

Blockchain technology has the potential to transform how the digital world manages data and conducts commerce. Originally designed to support Bitcoin, Blockchain has shown to have a level of adaptability and security that has caused many sectors of industry and government to take notice and begin implementing it. With that in mind, it makes sense to explore becoming a Blockchain developer if you’re looking for a job with a lot of room for advancement and a vibrant new technology that’s just getting started.

Even persons with a great understanding of technology principles misinterpret blockchains. As a result, entering or shifting into blockchain development may appear difficult. However, blockchain technology is not as mysterious as its name suggests.

What is a blockchain?

A blockchain is a database that is used to store and organise data. Traditional databases organise data into tables, which are made up of rows and columns. This makes it simple for computers to recognise the data. However, with blockchains, data is digitally formatted and organised into clusters or blocks. Each block has a finite amount of storage.

When that capacity is achieved, the block shuts and uses cryptography to link to the previous block, forming a chain. When one block joins another, cryptography provides an unchangeable timestamp. This permanent record ensures that sensitive data, such as transactions, remains accurate. Traditional databases, on the other hand, are usually managed by a single entity. An organization or administrator may manage and keep sensitive data.

Blockchain is popularly recognized as the backbone of cryptocurrency and is even mistaken for cryptocurrency on occasion but there is much more to it than that. We go into further detail about blockchain and how it works here

What is blockchain development?

Building, maintaining, and designing blockchain applications and systems are referred to as blockchain development. Overall, it aims to solve issues and generate opportunities by utilising the unique qualities of blockchain technology.

The smart contract is an example of cutting-edge blockchain development. Smart contracts, like ordinary contracts, are written agreements between two parties. Smart contracts, like regular contracts, are computer programmes that are stored on a blockchain. These programmes are only activated when both parties agree to the terms and conditions. This automated compliance ensures that a contract is correctly executed in real-time.

When it comes to smart contracts, comparing them to parking meters is an excellent approach to visualize their utility. You make the proper payment and receive the parking validation that corresponds to it. Because the agreement is established, no third-party intervention, such as a cashier, is required.

Who is a Blockchain Developer?

Blockchain developers are working on a blockchain network or a decentralised application for it. That isn’t to say that all blockchain developers are pros. However, they won’t be able to call themselves blockchain developers for long if they aren’t.

A certified blockchain developer is familiar with the blockchain architecture, underlying technology, and the steps required to integrate the many blockchain components into a single system. The developer understands how encryption and data structures integrate into the blockchain system, as well as how to implement effective consensus protocols and create decentralised apps and smart contracts.

A blockchain developer is also familiar with the programming languages that are used to create the blockchain components. Although not every blockchain developer has the same level of expertise in every area, they all have a broad understanding of what it takes to build a successful blockchain network and its applications.

There are two types of blockchain developers, namely:

  • Core Blockchain Developers
  • Blockchain Software Developers
Core Blockchain Developers

The architecture of a blockchain system, how its protocols should be designed, the design of the consensus protocol, and other high-level decisions and development relating to blockchain technology are largely the responsibility of core blockchain developers.

 In brief, their roles include the following:

  • Design of blockchain protocols
  • Design of consensus protocols and security patterns for the network
  • Design of the network architecture
  • Supervision of the entire network
Blockchain Software Developer

Blockchain software developers, on the other hand, produce decentralised apps that operate on blockchain technology using the architecture and protocols developed by Core Blockchain developers.

Developers of blockchain software have their own set of responsibilities. These responsibilities have nothing to do with the system’s consensus design or architecture. Blockchain software developers create decentralised applications or Dapps using blockchain technology, just the way a regular web developer uses the protocols and architectural structure set up by a core web architect to build web apps. Their responsibilities include:

  • Development of Smart Contracts
  • Development of interactive front-end designs for Dapps
  • Backend development pertaining to Blockchain
  • Supervising the entire stack running their Dapps

How to Become a Blockchain Developer

Blockchain jobs entail creating new ways to use blockchain technology or assisting businesses, governments, and organisations with the implementation of existing blockchain technologies. As a blockchain developer, you’ll be responsible for writing and testing code for applications that interface with and use the blockchain in financial, business, or data activities. You collaborate with engineers, architects, and others who have the qualifications and skills to create blockchain-based applications and software solutions. Journalists and marketing professionals may be tasked with writing on or promoting cryptocurrency goods and advancements as part of their jobs. Some businesses are dedicated to running computers that process and record blockchain transactions.

Top Blockchain Developer Skills 

Blockchain developers, as you’ve probably seen, have a lot of duties. They’ll require a few abilities to be able to handle such obligations effectively. In order to be a good blockchain developer, certain skills must be developed and mastered. To face and manage blockchain development, you should have the following primary blockchain developer abilities.

Blockchain Architecture

A blockchain developer should have a thorough understanding of the technology, how it works, and how it is built. Cryptographic hash functions, consensus,smart contracts and distributed ledger technologies should all be familiar to them. Going through the bitcoin blockchain whitepaper is the greatest approach to becoming familiar with blockchain technology; nevertheless, going through the entire whitepaper can be tiresome, and a little direction always helps improve the learning curve. Developers should also be familiar with the four types of blockchain architecture: consortium, private, public and hybrid.

Data Structures

When aspiring to be a blockchain engineer, you must have a thorough understanding and practical understanding of data structures. To satisfy their individual network requirements, blockchain developers are continually experimenting with and changing existing data structures like as Merkle trees and petrecia trees. Blockchain creates a safe and immutable system by combining a variety of data types with powerful cryptography. Knowledge of blockchain can only be considered incomplete if it is not accompanied by an understanding of data structures.

Smart Contract Development

Since the release of Ethereum, smart contracts have grown in popularity. Every blockchain is now attempting to add smart contract capability into its system, allowing business logic to be applied to the blockchain with ease. As a result, developers interested in working in the blockchain industry should learn about smart contract programming. This usually includes learning network-specific programming languages such as Solidity, Viper, Chaincode, and so on.


Because blockchain is a combination of data structures and advanced encryption, it’s only natural that a solid understanding of cryptography is also essential to working as a blockchain developer. Aside from asynchronous cryptography for producing digital signatures, blockchain uses a variety of cryptographic methods such as hash functions such as SHA256 and KECCAK256. It is hard to become a blockchain developer without first understanding how they work.

Web Development

A blockchain developer’s main skill is web development. When a blockchain developer first starts out in the sector, the bulk of them is responsible for the basic architecture of decentralised applications. This implies you must understand the fundamentals of both front-end and back-end programming, such as designing interactive graphical user interfaces for Dapps, API management, and request handling, among other things.

Programming Languages

Depending on the platforms used to develop blockchain environments, multiple programming languages are frequently employed. Although developers cannot be experts in all languages, they must be able to work in a variety of them. Java, C++, Python, and JavaScript are some of the more popular blockchain languages. Developers should also have a thorough understanding of object-oriented programming and be conversant with a variety of development frameworks and tools.

The Future of Blockchain Development

Because they deal with a revolutionary and innovative technology, blockchain engineers are in high demand. As a result, this field has a lot of job openings. Between 2020 and 2030, the US Bureau of Labor Statistics (BLS) predicts a 22% increase in software development jobs. According to studies, the blockchain sector would be worth more than $39 billion by 2025.

Developing abilities in a rapidly evolving technology will help you stand out as a job applicant. Furthermore, many blockchain developers earn a lot of money. According to Glassdoor, blockchain developers in the United States earn an average of $119,780 a year.
