What is Blockchain Development?

As the name suggests, Blockchain is a chain of blocks, “blocks” in this context are digital information connected using cryptography. Each block comprises a cryptographic hash function linking to the previous block, a timestamp, and the digital data. These blocks are structured in such a way that it is tough to modify the data and so they make sure transparency while simultaneously maintaining safety.

Blockchain is identical to security as tampering with these blocks is next to impossible. And that makes this technology widely held in areas like banking, finance, etc. Actually, Blockchain app development was first made famous when it was used to implement Bitcoin

In the end, people want their money to be safe. And therefore, Blockchain app developers are highly in demand. Moreover, learning the top programming languages for Blockchain Development will provide you a verge over other developers.

12 Best Programming Languages for Blockchain Development


C++ is well-known across the tech world, and this is true even in the Blockchain programming language. C++ is popular because of its numerous proficiencies such as move semantics, advanced multi-threading, primitive control over memory, and other object-oriented elements like runtime polymorphism, function overloading, etc. 

These different OOPS features of C++ permit Blockchain app developers to effortlessly mold data and functions together in a single module, just like Blockchain molds the blocks with cryptographic chains. C++ is also popular with Blockchain as Bitcoin, and the first-ever execution of Blockchain was primarily written in C++. 


Python development framework is used for building Blockchain applications.
Python development

Python is rapidly becoming the most popular programming language in the tech world. If you have a new Python developer experience, it might be the best Blockchain programming language for you. A problem with Python development is that it is an interpreted language that creates some issues for complex cryptographic operations in Blockchain. However, Python is an object-oriented language that helps in managing several of its performance-related overheads. 

Another advantage of Python is that app developers can prototype their ideas rapidly with any long-winded coding required. Python also has extensive open-source support, which makes it perfect for Blockchain development. Many Python libraries, plugins, Python development guides, and other resources are accessible online for almost every issue you encounter in Blockchain app development.


Java provides tough competition to C++ in popularity and effectiveness in Blockchain development. Java development has a plentiful Application Programming Interface (API) that contains several Java classes, packages, interfaces, etc. Therefore, it is suitable for building applications without essentially knowing their internal implementations. Also, the property of Java useful in Blockchain is its portability. 

Java programs can be ported onto different platforms because of their write once, run anywhere functionality. In addition, these programs are not dependent on system-specific architecture as they use the universal JVM (Java Virtual Machine) for execution. This portability, along with the other standard features, makes Java ideal for Blockchain app development.


Solidity is the fastest-growing Blockchain programming language designed to write smart contracts and runs on the Ethereum Virtual Machine (EVM). It was established by Ethereum, which is a Blockchain-based distributed computing platform and operating system. Although Solidity is designed keeping Blockchain in mind, it is appropriate to resolve issues encountered by Blockchain developers

Solidity is developed like the ECMAScript syntax, but it has helpful features like variadic return types, static typing, etc. Therefore it is a perfect programming language to learn if you want to accentuate Blockchain development deeply.


Vyper is the latest Blockchain programming language that originated from Python 3. As a result, the Vyper syntax is also effective Python 3 syntax, despite the fact Vyper does not have all of Python’s features. Vyper is developed as a substitute to Solidity. It is commonly used for the Ethereum Virtual Machine (EVM), just like Solidity is. 

However, Vyper holds different control structures than Solidity, and it also manages security issues differently. Furthermore, Vyper has similar functionalities and features to Solidity’s OOPS, such as infinite loops, modifiers, recursive calling, etc. As a result, it helps in avoiding the security issues that arise due to these features. So if you want a Blockchain programming language for writing smart contracts, look into Vyper.


JavaScript Development framework is used for developing Blockchain mobile applications.
JavaScript Development

JavaScript is the most popular programming language, and because of NodeJS, a JavaScript runtime environment, it is pretty popular with Blockchain developers. Moreover, they can develop competent and innovative Blockchain applications with JavaScript because it is already installed on most systems. Hence, the big advantage JavaScript has is against other programming languages since every web system uses JavaScript to some ability. 

So JavaScript developers do not need to worry about incorporation while using JavaScript, and they can focus on the application logic for the Blockchain. The Sidechain Development Kit (SDK) allows developers to build and publish their Blockchain apps in JavaScript. 


Go is an excellent programming language for developing quick and effective Blockchain systems. It is the ideal programming language for creating hyper ledger fabric, which is a base for developing applications for Blockchain. Since Go is statically typed and a compiled programming language, it is picture-perfect for Blockchain development.

It also has other features that enhance performance like generics, classes and inheritance, exceptions, constructors, annotations, etc. Go is also a straightforward language that can be learned quickly. Additionally, there are about 800,000+ developers on the Go language network.


C# is syntactically similar to Java and C++, so it is ideal for Blockchain programming. While C# was primarily created only as a Microsoft language, it is now quite popular and considered one of the best Blockchain programming languages. Open-source developers can effortlessly create a highly portable code using C# that will run across all devices and different operating systems like Windows, Mac, Linux, Android, etc. 

Furthermore, since C# is an OOPs programming language, Blockchain app developers can maximize performance when developing their next Blockchain. Projects written in C# include Stratis, a Blockchain-as-a-Service provider that allows businesses to effortlessly build applications on Blockchain platforms.


Simplicity is a high-level Blockchain development language that was designed for smart contracts. It is one of the best programming languages to write smart contracts for professional and open source developers.
