Best Programming Languages for Blockchain Development in 2022

Over the past few years, blockchain programming has become one of the hottest technology trends. Several sectors have also been identified as having potential for blockchain, including education, legal, travel, and healthcare. In the period 2017 to 2020, the demand for Blockchain development services grew by around 2000%, making it the most valuable technology. Also, it is estimated that the blockchain market will reach $20 billion by 2024.

Blockchain development services will be essential for any technology enthusiast, as Blockchain programming languages are dictating its existence.

Our list below includes some of the top programming languages that are useful for developing Blockchain applications.

  • Python

Python is quickly becoming the most popular programming language in the world of technology. If you have experience in Python development, it may be the best Blockchain programming language for you. However, Python development has the disadvantage of being an interpreted language, which poses some issues with complex cryptographic operations. Additionally, Python can manage several performance-related overheads as an object-oriented language.

Python also allows app developers to prototype their ideas quickly without lengthy coding. Moreover, Python offers extensive open-source support, which makes it suitable for Blockchain development. Online resources are available for almost every issue you may come across in developing Blockchain apps, including Python libraries, plugins, and Python development guides.

  • Java

Several Java classes, packages, interfaces, and APIs are available for Java development. As a result, it makes sense for building applications without knowing their internal implementation. Also, Java is portable, which is useful for Blockchain.

It is possible to port Java programs to different platforms because Java programs can be written once and run anywhere. Moreover, the JVM (Java Virtual Machine) used to execute these programs is not system-specific. Java is the perfect choice for developing Blockchain-based apps with its portability and standard features.

  • Solidity

Developed on the Ethereum Virtual Machine (EVM), Solidity is the fastest-growing Blockchain programming language.  Despite Solidity’s Blockchain-centric design, it can be used to resolve issues encountered by Blockchain developers.

Solidity is developed in the same way as ECMAScript, with the added benefit of variadic return types, static typing, etc. As a result, it is an ideal programming language to learn if you are interested in Blockchain development.

  • C++

Programming in C++ is well known throughout the world of technology, and this is also true of blockchain programming. C++ is popular due to its extensive features such as polymorphism at runtime, function overloading, and advanced multi-threading.

Blockchain app developers can use different OOPS features of C++ to easily combine data and functions in one module, just as Blockchain makes blocks with cryptographic chains. The first Blockchain program was primarily written in C++, and Bitcoin was created largely in C++.

  • JavaScript

Due to NodeJS, an environment for JavaScript runtime, JavaScript is quite popular with Blockchain developers. Furthermore, JavaScript is already installed on most systems, so they can create competent and innovative Blockchain applications. Because every web system makes use of JavaScript in some capacity, JavaScript has an advantage over other programming languages.

JavaScript developers can create and publish Blockchain apps using the Sidechain Development Kit (SDK).

  • C#

The syntax of C# is similar to Java and C++, so it also can be used for Blockchain programming. Although C# was originally designed only for Microsoft, it has now gained popularity and is known as one of the best Blockchain programming languages. Using C#, open-source developers can easily create highly portable code that will run on a wide range of devices and operating systems, including Windows, Mac, Linux, Android, etc.

Furthermore, because C# is an OOPs programming language, developers who create Blockchain apps can optimize performance.



Which Programming Language is Best for Blockchain?

Considered at the base of the cryptocurrency revolution, blockchain has made a name for itself in modern society. It helps people carry out transactions anonymously with other people. Blockchain also aided in the rise of popularity with bitcoin and other digital currency methods.

With blockchain continuing to be a part of companies’ systems, the need for blockchain developers has risen as well. Thus, developers should be aware of which programming language is best used with blockchain.


This is one of the powerhouse languages that has many features, adaptation capabilities, high-quality performance, and more. Java is best used for web development. It’s object-oriented, concurrent, class-based, and general-purpose too. Within the blockchain, Java is most helpful when creating web pages with high interactivity. It can also be used to develop simple, immutable blockchains. Developers in blockchain like this language because it has high portability and cross-platform capabilities. The combination of Java and blockchain has been incorporated into Ethereum, BitcoinJ, and IBM blockchain.


Known for its low learning curve and simplicity, Python has numerous libraries as well. Its extensive, active community of developers ensures the language is constantly improving. This programming language can be used to write smart contracts for blockchain, which the latter’s developers find extremely beneficial. Python and blockchain have led to the creation of smart contracts written for Hyperledger and NEO. Ultimately, it’s the combination of Python’s libraries, easy to learn the system, and wide range of uses that makes it a great language for blockchain development.


Unlike the other programming languages mentioned, C++ holds many principles that blockchain does. Some of these include:

  • Data hiding
  • Encapsulation
  • Polymorphism
  • Abstraction

In fact, C++ has helped form the basics that makeup blockchain. Bitcoin, the most widely-known use of blockchain was created using C++. Some of the language’s features like its object orientation and complex multi-threading capabilities are things blockchain developers love about the language. While Python is easier to learn, Java is harder to grasp and C++ is a bit more difficult to understand than Java. However, it’s very similar to the blockchain and has been behind the development of blockchain projects such as Ripple, Monero, QTUM, and Stellar.

Other Notable Programming Languages

JavaScript and Solidity are other programming languages blockchain developers could consider. While they are slightly less popular than most of the other languages mentioned, they have strengths of their own within the blockchain industry.


Developers all have their own methods and tools. Blockchain developers are the same way, though the foundation of every development project includes the choice of which programming language is used. The blockchain industry is becoming more popular, meaning the knowledge of things like Bitcoin is spreading as well. The benefits of blockchain development boil down to the implementation of languages such as Python, Java, C++, JavaScript, Solidity, or any other language that fits its overall purpose. A top choice would be C++ since it and blockchain are more closely connected. But, with its steeper learning curve, Python might be a simpler option. Java could be solid middle ground. In the end, analyzing each language in correspondence with the purpose of the development project will help developers decide which is the best one to use.
