Blockchain developers – Most popular languages to learn


You do not need to convince anybody about the importance of choosing a programming language. Depending on the knowledge of specific technologies and proficiency in using them, both the chances on the labor market and earnings shape. The world’s largest portals regularly publish reports that help to know which programming languages ​​are the most popular and make this difficult decision. Whether you’re looking for a blockchain job or want to learn more about what’s going on behind the scenes, you need to choose the right language for programming your blockchain. The six languages ​​listed below are one of the hottest trading tools in the world of blockchain development.


  • JavaScript

Invariably for several years now, the first place belongs to JavaScript. It is also considered relatively easy to learn. With its help, you can enhance the appearance of the website and enable its greater interaction with the user. JavaScript is used on almost every website, which means that the demand for people using this language is consistently high. JavaScript is a programming language that allows the implementation of complicated elements on the website, thanks to which this page can not only display static information, but also support changing content according to the situation, display interactive maps and 2D / 3D graphics, display video, etc. Does not exist now probably a universal programming language in terms of functionality such as JavaScript. In addition to being a high-level language, it allows the use of mechanisms such as classical inheritance, inheritance through prototypes, dynamic typing, regular expressions, or the use of functions as first-class citizens (so-called first-class citizens). It allows you to write simple scripts modifying the content of web pages, as well as advanced web applications using MVVM or MVC patterns. There is nothing better than a language that does not bind the programmer of hands at the very beginning of work. JavaScript perfectly suited for blockchain operations. As the number of users on your blockchain rises, you may have thousands or millions of people all performing actions at the same time. JavaScript can more easily handle the communications between all these different blockchain nodes. Note, however, that JavaScript isn’t as efficient as C++ in terms of maximizing your computer’s processing power.

Still, JavaScript is already a familiar presence on the web—and if you don’t already know it, it’s easy to get started. Using JavaScript lowers the barriers to entry for developers who are interested in programming blockchains.

  • C++


C ++ is a general-purpose language. Programs in C ++ can be commonly used in embedded systems and in game device. In C ++, operating systems (or parts of them) have been written, such as Apple OS X, IBM OS / 400, Windows NT, XP, Vista, 7. However, the use of C ++ is much wider, mainly where the performance of software is put, from desktop applications (including Adobe products such as Photoshop, Acrobat or Office suites) by servers (including e-commerce such as Amazon, eBay, search engines such as Chrome, databases, e.g. MongoDB), or AAA game engines parts (e.g., CryEngine, Unity, Unreal Engine).

In general, C ++ is used where efficiency and low resource consumption matter. C++ is a tried-and-true programming language that has stood the test of time. While it can be used for higher-level tasks, it also allows programmers to get very close to the hardware itself. This has made C++ highly popular for uses such as embedded systems and computer graphics.

Of course, this also means that C++ gives you a lot of power when building the actual blockchain infrastructure. If you want to make your blockchain as efficient and speedy as possible, optimizing the number of transactions per second, then C++ is a natural choice.

While C++ is by no means bad for smart contract work, it’s not automatically suited for doing it either. As a result, blockchain developers have created programming languages such as Simplicity to work on top of languages like C++.written to be cross-platform without any modifications, but only if we stick to the appropriate rules. Some properties / libraries are for specific systems. C ++ is most



Python is a language that programmers who do not use it yet, most often indicate as the one they want to learn. Like JavaScript, Python is easy to learn and a common entry point to the world of programming, especially for scientists and data analysts. Python enjoys a large, active community that has released libraries such as SciPy, NumPy, and Pandas for a variety of technical applications in math, science, and engineering.

In particular, Python is excellent at crunching numbers—taking large data sets and cleaning, processing, analyzing, and visualizing them. These skills lend themselves very well to data-driven industries such as finance and the Internet of Things.

Beyond these capabilities, Python is an excellent general-purpose programming language that can be used for both building blockchains and writing smart contracts.

Its interpreters are available on many operating systems. Python is developed under an open license by the Python Software Foundation, which is a non-profit organization. The standard language implementation is CPython (written in C programming language).


  • Simplicity

While C++ is more than 30 years old, Simplicity could hardly be newer. The language’s creator, Russell O’Connor, announced its release at a workshop in November 2017.

Simplicity is a higher-level programming language that allows you to write more human-readable smart contracts. The Bitcoin cryptocurrency already has a smart contract language called Bitcoin Script, but it’s fairly low-level and requires an advanced understanding of Bitcoin.

By abstracting many of these low-level concepts from Bitcoin Script, Simplicity makes it faster and easier than ever to write smart contracts.


  • Solidity

Solidity is a programming language that is intended for writing smart contracts for Ethereum-based blockchains. Solidity’s syntax was based on JavaScript, which makes the language easier to pick up, and it also borrows concepts from C++ and Python.

While it has many of the same advantages as languages like Simplicity, Solidity is designed specifically for use with the Ethereum blockchain network. Solidity allows programmers to write higher-level code which is then compiled down into low-level machine language.


  • Rholang

RChain is an ongoing development project that’s in the process of building Rholang, a concurrent programming language for smart contracts. Unlike the five languages above, which are object-oriented in design, Rholang is a functional language.

Functional programming is a different way of thinking about programming. Instead of using variables to hold values, and changing these values over the course of the program’s execution, functional programming sees programs as a series of mathematical functions to be evaluated sequentially.

A vocal minority of developers prefer using functional programming languages, such as Lisp and Haskell, due to advantages like elegance and concurrency. Although RChain and Rholang will offer many of the same capabilities as languages such as Simplicity and Solidity, Rholang operates in a specifically functional context. The project caters toward those blockchain developers who prefer to work in a functional programming environment.


To sum up ,

After reading about the six languages above, you’re undoubtedly wondering which of them is right for your project. Answering this question starts with understanding what you’re actually trying to do and what networks you’ll be working with. If you want to implement a new cryptocurrency, you can probably start with Bitcoin and Simplicity. Bitcoin is based on a proof-of-work blockchain, which you could copy and build out using Simplicity. You can also work with the established Ethereum blockchain using Solidity.

On the other hand, if you want greater control over creating your own blockchain, you can use languages such as C++, JavaScript, and Python to build the system and customize it however you want.
