Top Hardcore Skills Needed To Become a Blockchain Engineer

Metaverse, Web3.0 and NFTs are pushing the need for talented and certified blockchain engineers across the world. Crypto tokens, assets and data are all moving to blockchain-driven systems. It was data science and big data intelligence that raked in trillions of dollars in investments and provided millions of jobs in the last 10 years. Now, it’s going to be blockchain’s turn to do the same. We are witnessing a massive shift in the way the internet functions, and with the rise of blockchain as a core technology framework for engineering in the Cloud and AI, newer concepts such as Decentralized Finance, Hyperledger, and Embedded Crypto are expected to rule the roost for at least next 10-15 years.

In this article, we will focus on blockchain engineering and the top skills required to succeed in this lucrative career opportunity.

What Is A Blockchain Engineer?

Every company wants different skills; however, some basic technical skills are universal in the market and must be possessed by every blockchain aspirant. A blockchain engineer is a one-stop shop capable of designing, developing, analyzing, implementing, and supporting a distributed blockchain network. According to reports, blockchain jobs have increased by nearly 271% since 2020 and are expected to quadruple by the end of 2022.

Blockchain Engineer Job Skills Required

Based on our analysis of the job market in the blockchain development industry and the kind of projects that are attracting huge investments in the AI and Fintech markets, we identified these must-have skills for a successful career.

These are:

  • Core Programming
  • Core Product Engineering
  • Product Management
  • Embedded Blockchain
  • Digital Blockchain Marketing

A basic blockchain engineering job would seek a candidate with these skills:

  • Strong background in software development.
  • Proficiency in programming languages like C++, Java, JavaScript, C# (this mainly depends upon the project)
  • Experience in working with codebases.
  • Hands-on experience on open source projects.
  • Standard algorithms and data structures knowledge.

For advanced blockchain engineering roles, key blockchain skills:

  • Advanced knowledge of Blockchain-related technologies, data analysis and Cloud computing
  • Theoretical knowledge of decentralized systems and how these work in BFT and PBFT blockchain consensus
  • Crypto analysis
  • DLTs

Here’s a quick overview of how blockchain skills can be acquired.

What Are Blockchain Skills?

A blockchain developer is someone who possesses a diverse set of skills in data structures, cryptography, computer networking, and algorithms. They should also have prior experience with a specific type of blockchains, such as Ethereum or Bitcoin.

Have you heard that the value of bitcoin has doubled yet again? or the stock market is being taken over by new cryptocurrency IPOs! Cryptocurrency, on the other hand, is only the tip of the iceberg. Blockchain technology is much more than just cryptocurrency, and it has the potential to revolutionize almost every aspect of our lives.

Blockchain is used in a variety of industries, including healthcare, defense, cybersecurity, supply chain, and manufacturing. The demand for equivalent blockchain developers has skyrocketed as a result of this breadth of applications. In the blockchain industry, many designers, software developers, and analysts are just getting started. Basic expertise in Blockchain concepts related to cryptographic hash functions, consensus, and distributed ledger technology will help you gain more ground in the decentralized finance (DeFi) industry.

Let’s understand the role of different technologies and the skills required to adapt to the current requirements of the blockchain industry.

Blockchain Architecture

Blockchain developers should have an in-depth knowledge of the technology, how it works, and how it is built. Cryptographic hash functions, consensus, and distributed ledger technology are all concepts you should be familiar with.

Development of Smart Contracts

In 2021 and beyond, smart contracts were the most widely used application. The release of Ethereum 2.0 is the primary reason. Beginners should be aware that every blockchain tries to integrate smart contract functionality into its system so that business logic can be easily applied on the blockchain layer. As a result, developers interested in working in the blockchain field should learn about smart contract development, as well as its importance and business applications. It is usually necessary to learn network-specific languages such as Solidity, Viper, Chaincode, and others.

Data Structures

To become a blockchain developer, you must first learn data structures.


Because blockchain developers must build and implement networks, which necessitates frequent interaction with a wide range of data structures. Even a single block in the blockchain is a data structure in and of itself, so the entire blockchain network is made up of data structures. Learning about data structures will help you understand the fundamentals of blockchain.


As a blockchain developer, you’ll mostly be working on web applications, particularly in Web3.0. You’ll need to learn web design, app development, and programming, which will all help you create better Dapps. Because most organizations require blockchain developers to create apps that people with no or limited knowledge of blockchain can use, web development is essential.


To transact in cryptocurrency, you’ll need a wallet and the key to that wallet. That key is required because it establishes your possession of the wallet. Cryptocurrency transactions are secured by the encryption and decryption of public and private keys.

Cryptographic hashing is another important concept in cryptography. In cryptography, hashing refers to the process of producing a specific length output from any length input.

Object-Oriented Programming Fundamentals

Object-oriented programming, or OOPs, is the foundation of most programming languages. As a result, it has become an important part of the blockchain world. It will help you reuse code, solve complex problems, gain flexibility through polymorphism, and use modularity for easy troubleshooting if you have a firm grasp of it.

Recognize The Importance Of Standards And Eco-systems

Get familiar with blockchain principles and practices, and understand how they can be applied within your business environment, to build an effective blockchain system, simplify your business process, and drive the business outcome.


We’ll see a lot more growth internationally in the blockchain industry as we dive deeper with crypto and DeFi platforms. Many big companies are already investing heavily in this amazing technology, and there is still a lot to learn about it. Industry leaders and blockchain researchers should come together to develop a tailor-made Fintech and B2B tech focused blockchain skill upskilling program which will benefit everyone.
