Top 11 Programming Languages for Blockchain Development

Top 11 Programming Languages for Blockchain Development

Table of Contents

Blockchain is a decentralized, secure and very fast technology that is already making waves in the business world. The blockchain is beginning to run the world with numerous blockchain projects being developed and deployed on the internet. There are companies already trying to build on what other people developed. All of these blockchain developments are done in different programming languages, some of which are explained below. 

1. JavaScript 

This is a high-level programming language and more importantly, it is a weakly typed, dynamic, prototype-based and leading web technology in the world. This programming language is very popular, and there are already new frameworks being created for javascript, which can be used to develop codes. 

Javascript is very easy and you only need to understand the basics to start to work on this language. It is mostly used in blockchain development in ethereum.js and web3.js which are used to connect the application frontend with smart contracts and ethereum networks. It is also used for node.js in the Hyperledger Fabric SDK which is the framework that many big companies use. Another blockchain you can use javascript for is the NEO. 

2. C# 

C# is an object-oriented, compiled and high-level programming language that was created for Microsoft late into the 90s/the early ‘00s. Numerous ivory research has shown that this language is similar to C++ or Java, and it is more difficult to learn this language than the Javascript language. Although, it is also not as complicated as some other languages such as Go. 

There are a number of popular blockchain projects that the C# language is being used for. The most popular of such blockchain project is the NEO, something that’s popularly referred to as the Chinese rendition of Ethereum. Another popular blockchain project it is used for is IOTA, zero-fee transactions and highly scalable projects centered on IoT (Internet of Things). 

3. C++ 

This is an object-oriented, high speed, strongly static and compiled programming language. This language has access to hardware and high-level efficiency. Even though it was developed back in the 70s and 80s, as an extension of the C language. 

This language is quite complicated and is more difficult to learn than the C language, as some top writers have noted. And if you are a beginner or just learning to code, this language is not for you. 

Interestingly, it has been used in many popular and important blockchain cryptocurrencies and projects such as Bitcoin, Bitcoin cash, Eos, Monero, QTUM, Stellar, Cpp-ethereum, Ripple, Litecoin, etc. 

4. Python 

Python is a dynamically typed and trendy high-level programming language that supports functional programming and is also object-oriented. This programming language is growing in popularity than before and is the ideal language to use in developing artificial intelligence and machine learning features. 

Many big IT companies create frameworks and smart tools to support Python, and it’s often used to create chatbots. 

This very easy and popular language has also been used for numerous projects in the blockchain. One of such examples is its implementation of Ethereum, known as pythereum. It can also be used to create smart contracts for Hyperledger as well as NEO contracts. Python also has its own implementation of steemit known as steempython. 

5. Golang 

This language called Go for short, is a compiled, statically typed programming language that was developed by employees from Google. The idea of Golang is to have a combination of the efficiency of a compiled language such as C++ and the ease of developing codes such as Python. 

This language is quite complicated and developers at papersowl are of the opinion that it is very difficult to learn this language. However, most of the developers with this opinion are python and javascript developers. Developers on C++ will find it easier to learn Go. 

There are a lot of blockchain projects that Go has been used for. One of such is the Go-Ethereum blockchain written in this language. Another one is Hyperledger Fabric which is the blockchain solution that big organizations opt for.  

6. Solidity 

Solidity is a statically typed and contact-oriented programming language developed by the developers of Ethereum. This language was created the main language for the development of the smart contract, and is, therefore, the ethereum’s smart contract primary language. 

Solidity is like a smaller copy of javascript with little changes. It is therefore not very complicated. So if you’re a mid-level developer, it’ll take you just a few days to learn this language. 

This language is used primarily in the development of Ethereum smart contracts. 

7. Java 

This programming language, developed by Sun Microsystems, is a strongly typed language, based on object and class. Java is an object-oriented language popularly used in many big companies.

The difficulty level of java can be compared to that of C#, which is quite complicated and harder to learn than python or javascript. But still, this programming language is still very popular and there are numerous custom papers to help if you are just learning to code. But it is difficult to tell which is easier, Java, C++ or Golang? 

Java is also used very widely in the blockchain industry. It is popularly used in IOTA, P2P cryptocurrency and NEM platform also uses java. Other objects where java is being used in the blockchain are the IBM blockchain, NEO contract, Ethereum, Bitcoin J, Hyperledger’s contract. 

8. Rust 

Rust is a strongly typed and compiled programming language that has been sponsored by Mozilla since 2009. This language is very similar to the C++ programming language, so you really can’t say that it’s a language that can be learned easily. The entry level for this language is high as it has a very small community, so we can safely rate its difficulty as hard. 

There are only very few blockchain projects using this programming language. Parity is one of the few. A secure and fast ethereum client written in Rust. The most popular blockchain project written in Rust is the Ethereum Classic, a cryptocurrency birthed after Ethereum was hacked. Exonum, a security-oriented blockchain framework is also written in Rust. 

9. Ruby 

Ruby was developed in Japan by Yukihiro Matsumoto in the 1990s. This programming language is purely object-oriented. In fact, everything is an object in Ruby apart from the blocks, and they also have their replacement in procs and lambda. 

Ruby was developed to act as a buffer between the underlying computing machine and human programmers. The syntax of this programming language is similar to other languages like Java and C, so it’s easier to learn this language for C and Java programmers. 

10. CX

CX gives pointers, propelled cuts and array, and it also possesses the simple error control highlights which makes it convenient to design any blockchain with it. It was assembled over Go initially, and this stops the frameworks of CX from performing discretionary codes, which is a problem associated with business programming. 

This programming language was made for the blockchain development of Skycoin, with a capacity for it to work as an intermediary for digital contracts. 

CX integrates with Open Graphics Library (OpenGL) and uses the capacity of the GPU proficiently. 

11. Simplicity 

This is a relatively new programming language birthed in late 2017. It was designed mainly for blockchain development and smart contracts. It helps to increase productivity by hiding low-level logical components. 

This language is object-oriented, similar to C++, and it uses blockchain principles to prevent data changes and errors. 

The developers are still working on expanding the capabilities of this language, the features are going to be finalized and it will be added to bitcoin. So, we expect that from mid-2020, Simplicity should have more applications. 


Blockchain technology which makes it possible for us to have cryptocurrency exchange is, without doubts, here to stay. Blockchain developments are getting better with languages such as simplicity being specifically to make blockchain development a smoother process.
