3. Java

All thanks to the JVM (Java Virtual Machine) making Java a popular Blockchain programming language for app development. JVM makes it ideal for creating robust and portable Blockchain applications.

Further, its versatility allows you to create cross-platform blockchain applications that can operate well on different devices. The perfect example of a project in Java is Hyperledger Fabric, which is favored by enterprise-level blockchains. 

Now the question arises, “What type of software application you can develop using Java?  

Developing a blockchain app with Java starts with block mining, adding a block to the blockchain, calculating the hash, verifying the blockchain, and then verifying every transaction. Next, it applies an alternative consensus protocol, mining the reward, checking the node types, and securing the communication with cryptography. 

Java is the oldest and most trusted blockchain programming language considered by developers. Here are a few more reasons:

• Ensuring cross-platform portability across platforms.
• It offers object-oriented features for secure code. 
• Providing high-performance virtual machine capabilities 
• Being one of the matured languages, Java is suitable for enterprise-level blockchain solutions. 

4. C#

C# is an open-source programming language developed by Microsoft, which is a perfect alternative to Java. As it is often used in enterprise-grade apps, therefore it is considered an excellent choice for blockchain apps with commercial or enterprise use cases.

According to the reports, there are approx 5 to 8 million developers worldwide using C#. The Straits blockchain framework and Neo blockchain platform also support C#, providing .NET developers with a familiar environment for building decentralized apps. 

Though the market is already flooded with DApps, therefore, it makes sense to hire a software developer who can help you implement innovative features and functionalities that add edge. 

The common strengths of C# for Blockchain app development are:

• Offering support to high-level libraries
• Ensuring .NET compatibility for easy blockchain app development
• Easy integration with Windows-based enterprise solutions.

5. C++

C++ is a successor of Java and C programming languages, which work on core object-oriented programming principles. It is known for its performance and control over system resources. The original Bitcoin codebase is in C++ and many more blockchain platforms are still relying on C++ for performance-oriented tasks. 

In addition, Litecoin, Ripple, Stellar, and EOS are the leading giants, trusting C++ for blockchain development. Despite being first used back in 1985, it remains a popular choice among blockchain developers to create FinTech apps. 

Apart from here are the key highly making C++ a popular Blockchain programming language for app development:

• Ensuring efficient CPU management and memory control.
• Offering high-performance capabilities by easily running parallel and Non-parallel threads. 
• It ensures low-level manipulation of data and resources.
• There is a possibility of code isolation for different data structures.

6. PHP 

PHP is the strongest programming language that is not traditionally associated with Blockchain but is perfectly suited for building backend services for Blockchain-based Decentralized apps. 

PHP’s extensive use in web development makes it highly suitable for creating interfaces and interacting with the blockchain from a web server perspective. 

The core reasons to choose PHP as the Blockchain programming language for app development in 2025:
