Blockchain Developer is not just a programmer, they must have knowledge of many other fields such as economics, cryptography,… Let’s find out the 5 skills required in a Blockchain Developer below:
Algorithmic thinking and data structures
For a programmer, algorithmic thinking and data structures are the basic foundation for developing future products. With a complex system like Blockchain, without a foundation of thinking, the generated algorithms will not be able to instruct the computer to properly execute the original command. The task of the algorithm is to solve the problem and execute the instruction, so the main need is very high logic.
Proficient in at least 1 high-level programming language
Popular high-level programming languages include: C++, Golang, C#, JavaScript, Solidity, Python, Ruby, and Java. For programmers in the Blockchain field, it is imperative to know Solidity to work with smart contracts. The remaining languages will be more related to algorithmic programming. Programming language requirements will vary depending on the requirements of the blockchain administrator. Thus, in fact, Blockchain Developer needs to know at least 2 programming languages to work with this technology.
Understanding Blockchain technology, Smart Contract
In addition to the background of programming knowledge and skills, understanding the necessary information about Blockchain and smart contracts is a must. Programmers need to understand how Blockchain works, as well as the working protocol of Smart Contracts, from which to think well about appropriate and effective algorithms.
Knowledge of cryptography
Cryptography in Blockchain is very important. Blockchain is safe because it works on a decentralized application platform and secure cryptography. Understanding cryptography, cryptographic thinking will help you become a good Blockchain programmer. Your task will be to create secure ciphers to secure the information in the blockchain without the need for third-party intervention.
Blockchain Architecture
What makes Blockchain technology different is its decentralized system. The blocks are chained, not a single block as the server. All to create a highly secure and fair system. And such a complex, non-hierarchical system needs to be logically and meticulously designed. The blockchain architecture in the system will also be accompanied by a specialized website design. Thus, Blockchain Developer needs both architectural thinking and web development thinking. There are three common types of blockchain architecture today:
- Consortium architecture: The architecture is not completely decentralized, one group in the system will have full authority. This group is formed from several chain organizations in the system.
- Private architecture: In this architecture, the number of members of the system is not many, so they are not hierarchical.
- Public Architecture: This is the most decentralized architecture of Blockchain, applied in Bitcoin. In this architecture, an instance only needs to make one transaction to become part of the blockchain.
Becoming a Blockchain programmer may only require 5 skills but all of the above skills are very important. Fully equipped with these 5 skill groups will help you become a Blockchain Developer and can develop further in the future.
