Blockchain developers that are qualified need a variety of abilities. Choosing which talents to focus on developing when beginning a career in blockchain development might be challenging.
Blockchain job listings can provide candidates with some insight into what employers are looking for, but these “criteria” typically cater to a company’s particular requirements. However, there are six fundamental abilities for blockchain developers that any professional should have.
Who Is a Blockchain Developer?
Blockchain developers are actively developing a blockchain network or a decentralized application for that network. This does not imply that all blockchain developers are educated experts. If not, though, they won’t be able to use the title “blockchain developer” for very long.
A skilled blockchain developer knows the blockchain architecture, supporting technologies, and requirements for integrating the many blockchain components into a cohesive whole. The developer is skilled in implementing efficient consensus protocols, creating decentralized applications, and creating smart contracts. They also understand how cryptography and data structures relate to blockchain architecture.
A blockchain developer is an expert in the programming languages required to create the blockchain components. Although not every blockchain developer has the same level of expertise in every field, they are all well-versed in the requirements for deploying an efficient blockchain network and its applications.

Cryptography
Developers should have a solid foundation in cryptographic principles and techniques, including wallets, keys, and digital signatures, in order to provide a safe blockchain ecosystem. They should be familiar with the differences between cryptographic hash methods like SHA-256 and Keccak-256 and how to employ public-key cryptography to prevent unauthorized access to data.
-
Web development
Web development and blockchain go hand in hand, especially given the latter’s focus on decentralized applications. Blockchain engineers must have extensive web development knowledge. This necessitates not only having a working knowledge of web application design and development but also of the supporting technologies and the steps necessary for their optimization and security.
-
Blockchain Architecture
Blockchain engineers should have a thorough understanding of the architecture behind blockchain as well as how it functions. They should be knowledgeable about any other ideas necessary to comprehend how blockchain functions, including distributed ledgers, smart contracts, consensus, cryptography, and hash functions. The four different blockchain architectures—consortium, private, public, and hybrid should also be understood by developers.
-
Smart contracts
Self-executing contracts, known as smart contracts, let two parties transact goods and services directly amongst themselves. Developers should understand what smart contracts are and how they enforce business logic because they have become a standard component of blockchain systems. Blockchain engineers need also be knowledgeable in the popular smart contract programming languages like Vyper, Solidity, or Chaincode.
-
Programming Languages
Multiple programming languages are frequently employed in blockchain technology depending on the platforms used to construct the blockchain ecosystems. Even if they can’t be experts in all languages, developers must be competent in a variety of them. The more popular blockchain languages include Java, C++, Python, and JavaScript. Additionally, developers should have a solid background in object-oriented programming and be knowledgeable about various development frameworks and libraries.
-
Data structures
Data structures make up the blockchain network in its entirety. A sort of data structure that groups transactions for the public ledger are each block, which may be thought of as a unit. Blockchain developers must often use data structures, and they must be aware of their functions inside the blockchain network. Additionally, they need to be knowledgeable about the several categories of data structures, including graphs, heaps, hash trees, Patricia trees, and Merkle trees.
Final Thoughts
There are numerous jobs and responsibilities for blockchain developers. They may be in charge of the blockchain network, the software that runs on it, or a combination of the two. Additionally, they might take part in developing blockchain networks and apps, assessing current systems, and testing out new technology.

Although different employers may place varying values on these abilities, all six are necessary for a successful blockchain engineer. However, they are not the only blockchain competencies that developers ought to have.
They should possess fundamental abilities like comprehension of DevOps techniques, team source control use, participation in code reviews, developing secure and effective code, and keeping up with new technologies. They should also be well-versed in open standards and technologies that advance interoperability and possess excellent cross-disciplinary skills. Additionally, effective participation in today’s Agile development environments requires soft skills like teamwork and communication.
