7 Best Programming Languages To Use In Developing A Blockchain Software

When you hear Bitcoin or cryptocurrency being discussed, more often than not the word “blockchain” is tossed around the conversation.

Blockchain is a type of database that is different from normal databases because of the way it stores data. Blockchain stores data in blocks that are chained together. Hence, the name “Blockchain.” It took off, becoming a billion dollar enterprise, because of how secure it is. It is near impossible to tamper with the blocks in a blockchain.

Blockchain removes the middle man when it comes to transactions. Because of its security features, transactions between two strangers on opposite sides of the world can go through without a hitch and without breaching anyone’s trust.

Because of its popularity, an increasing demand for blockchain developers has risen – a trend that looks like it might go on for years as the field develops even further. Blockchain programming depends on the right blockchain development and learning the right languages (whether they are visual, object-oriented, or text-based languages) used.

Best programming languages to use for blockchain development


C++ is one of the most popular programming languages. It is an object-oriented language that was used by the founders of Bitcoin. The first implementation of blockchain was actually written in C++.

This language has multiple capabilities essential to blockchain like multi-threading, memory control capabilities, function overloading, move semantics, and polymorphism. C++ has the capability of preventing accidental data alteration and it can also handle both parallel and nonparallel tasks efficiently.


Solidity is a newer programming language. It was developed by Ethereum to work within the Ethereum Virtual Machine (EVM). Because it was developed specifically for blockchains, this language has the tools that can address blockchain development issues that one may encounter when developing blockchain programs.

If you are thinking of dipping your toes into the blockchain development pool, this is a very good language to start with. You can use Solidity to create smart contracts within the EVM.


Java is another object-oriented language and is nearly as popular as C++. One of the best properties of Java is its portability. The portability is attributed to its Write Once Run Anywhere (WORA) functionality. This means that you can run any Java written program anywhere as long as you have a Java Virtual Machine (JVM).

You can use java to create smart contracts. Java has the capability of managing large numbers of users in a blockchain network in real time. And you can create applications using Java without having to know the internal implementations of those applications.


Python is another popular programming language. If you are a new developer proficient in Python, it might be a good starting point for you when it comes to blockchain development. You can use it to create prototypes while avoiding long codes.

Blockchain platforms like NEO and Hyperledger use Python. It has easier syntax and has a large open source support. This means that there are tools, resources, and plugins for Python online that can help you solve any hurdle you might encounter while developing your blockchain program.

Go or Golang

Go is a new language developed by Google to build decentralized systems. This is the perfect programming language for creating hyper ledger fabric, a foundation for developing blockchain applications. It uses “Goroutines” instead of threads which means that multithreading can be performed without having to worry about memory.

It is a statistically typed and compiled language and was used to develop blockchain programs like Dero, Ethereum, and Hyperledger Fabric. It is fast, efficient, and very easy to use. It is a very easy language to learn and has advanced capabilities that makes it work very well in blockchain programming.


Javascript is one of those near omnipresent languages in websites and computer applications. Its widespread use makes it an ideal language to use for blockchain development. Most systems already have Javascript installed so using the language to develop blockchain applications just makes sense because integration with these systems will not be a problem.

Javascript can handle asynchronous code. Asynchronous programming is a type of parallel programming that allows one thread to perform a separate action from the main thread. This means that your blockchain can perform multiple tasks at the same time.


C# is another object-oriented programming language and was initially developed as Microsoft language. It is syntactically similar to Java and C++, two other languages in our list of best programming languages for blockchain.

C# programs can work across platforms, which makes it ideal for blockchain applications that are deployed to various operating systems like Windows, Mac, and Android. NEO was written in C# and blockchain projects like Stratis also use this language.


Whether you are a pro, a neophyte, or someone just about to learn programming and are interested in blockchain development, choosing the right language is an important starting point. If you are a pro familiar with C++ or Java or any of the languages used in blockchain programming, start learning by finding a blockchain that supports the language you know. From there you can branch out to other languages.
