A blockchain developer has the knowledge and skills to develop and optimize blockchain-based decentralized applications or dApps and smart contracts and blockchain architecture and protocols. They likewise deal with 3D modelling, 3D design, 3D content development, as in game development.

How to Become a Blockchain Developer?

The Roadmap to becoming a Blockchain Developer.

With an average salary of $154k per year and steady job growth, now is the ideal to learn blockchain development. Blockchain developers wield various skills to create and improve blockchain technologies, including computer networks, cryptography, algorithms, and data structures. These developers are responsible for designing blockchain technology focused on a specific business model and then building, launching, and maintaining a blockchain network. To achieve this, they must develop protocols, design the architecture of blockchain systems, and develop smart contracts and other web applications using blockchain technology. Additional responsibilities include:

  • Evaluate applications for new tools and technologies as they evolve.
  • Maintenance of client/server-side applications used for integration and business logic.
  • Stay up to date through new developments in the blockchain community.

The exact definition of blockchain is a system in which a record of transactions made in cryptocurrencies is kept through several computers connected in a peer-to-peer network (Oxford Languages). Blockchain is the technology that supports cryptocurrencies and allows them to function decentralised.

Who is Hiring Blockchain Developers?

Many Fortune 500 companies, including IBM, Accenture, Capgemini, JP Morgan Chase, and Microsoft, have expressed a need for competent blockchain developers. With cryptocurrencies gaining more traction, influence, and credibility, there has never been a better time to become a certified blockchain developer.

Two Types of Developers:

Leading blockchain developers research, design, and develop the architecture, security patterns, and protocols or technologies of blockchain. They monitor your entire blockchain network.

Blockchain software developers build decentralized applications (DApps), web applications, and smart contracts using the core web base architecture created by the lead developer/architect. They also oversee blockchain-related back-end development and oversight of the stack that runs their DApps.


Back-end development of DApps includes using the Solidity language, the official language of the Ethereum platform, to communicate with the blockchain for data and transactions.

For front-end development, use Python or JavaScript for interaction with the Ethereum blockchain.

Types of Blockchain Developers

Types of Blockchain Developer

1) Core Blockchain Developers

These are responsible for developing and optimizing the architecture. The developer will design, develop and enhance the protocols that support a blockchain solution. A good example is the consensus protocol that defines how members using the blockchain and its resources agree to share and use these resources.

  • They also make decisions related to them.
  • They implement the functionality and structures of the blockchain and ensure that they work as intended.
  • And also, they design and implement network security.
  • They ensure that the network is operational.
  • They plan, design and implement integrations of the blockchain network with other services.
  • However, they plan to extend the features and functionality of a blockchain network.

2) Blockchain Software Developers

They develop and implement the design according to the lead developer’s plan.

  • They develop dApps.
  • Therefore, they implement smart contracts as designed by the core developers.
  • They ensure that apps run as planned.
  • The investigation and care of integrating the blockchain network with other services and applications.

3) Back-end Developers

They can design and develop APIs, carry out performance tests, implement blockchain, design software specifications, work together with other developers to build software, and provide technical support.

List of Top 4 Courses for Blockchain Developers

The top 4 courses are listed below:

  2. Blockchain Developer Online Bootcamp 2020 by Consensys
  3. Solid Ethereum Blockchain Developer Bootcamp (2020)
  4. Blockchain for developers from Lighthouse Labs

How do I start?

As stated above, blockchain developers use a variety of skills necessary to keep their blockchain network secure and efficient. Some of these skills include:

Blockchain Architecture

Blockchain developers must be well-versed in cryptographic hash functions, consensus, and distributed ledger technology. A great resource to get started is the bitcoin blockchain whitepaper to get familiar with these technologies.

Data Structures

However, blockchain developers constantly experiment with different data structures to see which one works best with their specific network functions.


Many cryptographic practices are used to build blockchain networks, such as hash functions and asynchronous cryptography (for digital signatures).

Smart Contracts

Meanwhile the launch of Ethereum, smart contracts have to convert common practice. Firstly, most current blockchains embed smart contract functionality into their systems to apply business logic to the blockchain network. To learn and master smart contract development, you need to learn network-oriented languages ​​like Solidity, Viper, and Chaincode.

Web Development

Arguably, web development is the most crucial skill you can wield in blockchain development. When you begin your career as a blockchain developer, most of your responsibilities will include the basic design of decentralized applications. And also, to achieve this, you need to master front-end and back-end web development. It has but is not limited to creating interactive GUIs for DApps, API handling, and request handling.

Sites, where you can learn the language of robustness include cryptozombies.io, where you can learn by creating fun collectable crypto games, Udemy.com, Edureka. Co, and ethereum.org.

What is Prajix?

And also, the best way to master the world of coding is to put that world at your fingertips. Our mission is to allow developers worldwide to revolutionize the future we want to have through online collaboration.

And also, we allow developers to create or join project ideas on our platform, where they can find like-minded people to team up and collaborate with within our collaboration rooms.

However, we strive to build the most valuable network of programmers, coders, and developers from around the world in one place, creating a technological powerhouse that will help people and communities across the globe.


We have seen a lot of information that will be relevant on your way to becoming a great blockchain developer. We cannot see all those aspects in detail in a single article, so this is an introductory summary. If we were to delve into the programming aspects, we would require several pieces, and it honestly doesn’t make much sense at this point, mostly because of how scary it can be. I hope that this guide serves more to push you to work for what you want and that it works as an orientation towards a fascinating new technology.
