Top Blockchain Programming Languages: Choose the Best One for Your Business


Which programming language should you use for blockchain development? It’s the most common question many businesses ask themselves when deciding which programming language to adopt for blockchain development projects.

Blockchain is a new technology that has gained popularity in recent years. The technology allows fast and easy transactions between various parties on the internet without third-party intermediaries.


As per a report, The global blockchain market will grow to $39.7 billion in 2025, with a CAGR of 67.3% during 2021-2025.

Blockchain, when coupled with other technologies such as cloud computing, can be very powerful for businesses looking to improve their services in terms of security and efficiency. 

In this blog, we’ll explore the top-five blockchain development languages used by blockchain developers to help you decide which one would be the best for your project. We will also highlight their pros and cons and offer some advanced tips to choose them wisely.

So let’s Start!

The Best Blockchain Programming Languages

1. Solidity


Solidity is a new and exciting blockchain programming language gaining popularity over the past few years. Especially with its ability to develop dApps, many businesses are choosing this programming language.

Moreover, it is a high-level programming language like JavaScript, C++, and Python. Like these other common languages, it’s contract-oriented, which means smart contracts are responsible for storing all of the logic used in blockchains, making this one of today’s top blockchain coding options.

If you want to build your smart contract on the Ethereum blockchain, Solidity is an excellent programming language for this purpose. Smart contracts that run in alternative blockchains are easily portable with just one line of code.

Although it might be new compared to other programming languages (such as C or Java), over 200 thousand developers already use this powerful tool. Hence it might be easier for you to hire blockchain developers.

Key Features

  • Solidity is developer-friendliness.
  • Apart from Ethereum, you can use solidity for programming smart contracts on other platforms like Monax.
  • It offers accessibility to JavaScript infrastructures, debuggers, and other tools.
  • Statically typed programming.
  • Feasibility of inheritance properties in smart contracts.
  • It gives you precise accuracy

Some Examples of blockchain projects that use Solidity: 

  • Ethereum
  • Chainlink
  • Sushiswap
  • Compound Protocol

2. Java


Java is one of the best blockchain programming languages for smart contracts. It is classic programming, and developers employ it to develop countless applications and games.

Java is ubiquitous, so it is used in one way or another in almost all web systems, leaving developers free to manage app logic and dodging the need to focus on integration. It offers programmers the flexibility to write code that can be used on other systems as well.

Moreover, Java’s excellent code portability is the primary reason why several blockchain companies use Java to develop their applications. It has been used in creating smart contracts such as Truffle, ARK.

More than 10 million Java developers are available worldwide, and over 15 billion Java devices are running globally.

Key Features

  • Java provides extensive support for OOP (Object-Oriented Programming) methodology.
  • The facility of memory cleaning.
  • Availability of extensive libraries.

Some Examples of blockchain projects that use Java: 

  • NEM
  • IOTA
  • Ethereum
  • NEO 
  • Hyperledger
  • Fabric

3. Python


Python is a preferred language for developing smart contracts and blockchain-based projects. It’s often used in crypto exchange development, even though it can be easily extended to work with other cryptocurrencies as well.

As per TIOBE and PYPL ratings, Python has seized the opportunity to be in the top five blockchain development languages in 2021.


Python is a robust and versatile language that can reduce development time, making it one of the top choices for developing blockchain applications.

Moreover, it offers open-source support and frameworks with libraries such as Numba, which speeds up code without sacrificing performance or security.

Key Features:

  • Python gives access to dynamic architecture.
  • It is the perfect language for base and scripting approaches.
  • It offers open-source support.
  • In Python, blockchain coding is efficient for prototyping.

Some Examples of blockchain projects that use Python: 

  • Hyperledger Fabric 
  • Ethereum 
  • NEO
  • Steemit

4. Golang


GoLang is a compiled multi-threaded programming language developed internally at Google. It allows for different processes to run simultaneously, which means that it can handle multiple parts of blockchain concurrently and effectively.

Extremely fast with accessible maintenance features makes Go the perfect choice when distributing your dApp on Ethereum’s network as well.

Today, the Hyperledger Fabric blockchain platform uses this programming language. Plus, it has become one of the more popular ones in NFT marketplace development.

Key Features

  • Golang is user-friendly.
  • It is scalable, flexible, and offers high speed.
  • Golang combines C++, Java, and Python features to create a reliable and fun language to use for blockchain development.

Some Examples of blockchain projects that use Golang:

  • GoChain
  • Dero
  • Loom Network 
  • Ethereum 
  • Hyperledger Fabric

5. C++


C++ is one of the top languages for building blockchain apps. It’s easy to manipulate blocks and chains with this code, making C++ a perfect choice when you need complete control over your system resources.

The power of C++ lies in its flexibility and ease of use. It provides a wide range of control over how you want to handle your code, whether through giving full access or just some limited aspects that suit your needs.

It is a crucial programming language that developers used to code bitcoins, but today its applications span many blockchain-based projects. It was originally designed for the sole purpose of coding the decentralized cryptocurrency system.

Moreover, It can be seen in many other cryptocurrencies like Ethereum’s smart contracts or even Ripple’s XRP Ledger, which stores information about all transactions.

Key Features

  • C++ has efficient CPU management and memory control.
  • It provides an option to move semantics for copying data effectively.
  • It gives you the facility for code isolation for different data structures and more.

Some Examples of blockchain projects that use C++:

  • Monero 
  • Ripple 
  • EOS 
  • Stellar
  • Litecoin

Final Take!

It was all about the best blockchain development languages ruling over the world of cryptocurrencies and smart contracts in 2021.

There are several different programming languages for developing blockchain-based products. Yet, there’s no clear winner among them, and it can be difficult to say which one is best in each situation. Because they all have their advantages depending on the project you’re working on.

So, you need to pick any of the languages as per your project’s requirements like resources, budget, time, features you want to add, and others.

Since there are several different blockchains to choose from for various projects, before making the final decision, it is always more fruitful to consult with the best blockchain development company that can help you figure out which blockchain will work best.
