Qualified blockchain engineers must possess a varied set of skills. When starting a career in blockchain development, it might be difficult to identify which skills are most important to obtain. While job advertisements can provide you with some insight into what employers are searching for, these “requirements” are frequently adapted to the needs of the organization. There are, nevertheless, six essential blockchain development skills that any expert should possess.

The 5 Biggest Blockchain Trends In 2022

1. Understanding the structure of the blockchain

Engineers working on blockchains should have a solid understanding of how the technology works and the architecture that supports it. They should be familiar with cryptography, consensus, hash functions, distributed ledgers, smart contracts, and any other ideas necessary for understanding blockchain’s inner workings. Developers should be aware of the four types of blockchain architecture: consortium, private, public, and hybrid.

2. Cryptography

To create a secure blockchain environment, developers must have a solid understanding of cryptographic concepts and procedures such as wallets, keys, and digital signatures. They should be able to distinguish between cryptographic hash algorithms such as SHA-256 and Keccak-256, as well as how to use public-key cryptography to prevent unauthorized data access.

3. Organizational structures.

The entire blockchain network is made up of data structures. Each block can be regarded as a type of data structure for the transactions in the public ledger. Blockchain engineers must frequently employ data structures and understand how the blockchain network uses them.

4. Creating Smart Contracts

Smart contracts are self-executing contracts that allow two parties to exchange goods and services without the involvement of a third party. Blockchain engineers should be aware of smart contracts and how they enforce business logic, as they have become a common part of blockchain systems. Vyper, Solidity, and Chaincode are examples of smart contract programming languages that blockchain engineers should be familiar with.

5. Web development and design.

Blockchain engineers should be able to cover all aspects of web development. This necessitates not only understanding how to design and build online apps but also how to optimize and secure them utilizing the technology that supports them.

6. Multiple Programming languages.

Multiple programming languages are typically utilized depending on the platforms used to construct blockchain ecosystems. Blockchain engineers must be able to work in a variety of languages, despite the fact that they cannot be specialists in all of them. Some of the more prominent blockchain languages are Java, C++, Python, and JavaScript. Blockchain engineers should also be familiar with a number of development frameworks and tools, as well as a deep understanding of object-oriented programming.

While different firms value these skills differently when hiring Blockchain engineers, all six are required for a successful blockchain developer. These aren’t, however, the only blockchain skills that developers should possess. They should be able to understand DevOps practices, collaborate with others on source control, participate in code reviews, produce efficient and secure code, and stay up to date on new technologies. They should also be able to work across disciplines and have a strong grasp of open standards and interoperability technology. In today’s Agile development environments, soft skills like communication and teamwork are also necessary.

How do you become a Blockchain engineer?

There are no definite rules for becoming a Blockchain engineer, but professionals can start by following a few guidelines.

Learn everything you can about blockchain technology’s ideas and underpinnings. Learn everything there is to know about blockchain issues like cryptography, consensus, blockchain protocols, public-key encryption, decentralization, smart contracts, wallets, hashing, and more.
Reading white papers, enrolling in courses, working through tutorials, attending online training, and pursuing blockchain certifications are all good options. A variety of free and low-cost materials are currently accessible for learning blockchain.

Get hands-on experience with all aspects of the technology to better understand the fundamental ideas of blockchain. Establishing a private blockchain network is a viable option. Examine decentralized applications available on platforms such as GitHub before submitting your own. Consider acquiring a small quantity of bitcoin to get a sense of how it works from a user’s perspective.

Learn about EOS, Ethereum, Ripple, and Hyperledger, as well as other current blockchain development tools, technologies, and platforms. Free trials can be used to learn more about the various tools and to obtain a better knowledge of the fundamental blockchain concepts.
Join groups and associations dedicated to growth. Participate in community events and forums. Speak with programmers who specialize in blockchain technology. Look for alternative opportunities to get involved in the blockchain community. Keep up with the latest blockchain news.

Companies looking for blockchain engineers frequently seek candidates with a degree in computer science or a related field. Although this isn’t a hard and fast rule, keep in mind that it could be an issue. Apart from that, you have a plethora of options for furthering your blockchain career.
