2. 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 third­party intermediaries.
As per a report, The global blockchain market will grow to $39.7 billion in 2025, with a CAGR of 67.3%
during 2021­2025.
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 top­five 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
We are in the process of writing and adding new material (compact eBooks) exclusively available to our members, and written
in simple English, by world leading experts in AI, data science, and machine learning.

3. 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 high­level programming language like JavaScript, C++, and Python. Like these other
common languages, it's contract­oriented, 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 developer­friendliness.
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

4. 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 (Object­Oriented Programming) methodology.
The facility of memory cleaning.
Availability of extensive libraries.
Some Examples of blockchain projects that use Java:
NEM
IOTA
Ethereum

5. NEO
Hyperledger
Fabric
3. Python
Python is a preferred language for developing smart contracts and blockchain­based 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 open­source support and frameworks with libraries such as Numba, which speeds

6. 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 open­source 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 multi­threaded 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 user­friendly.

7. Golang is user­friendly.
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 blockchain­based 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.

8. 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 blockchain­based 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.
