Top 5 programming languages to build smart contracts

The demand for blockchain has skyrocketed in recent months. The worldwide epidemic has moved the world's focus to digitization. 


In the midst of this confusion, blockchain technology has arisen as a very productive, safe, and transparent means of transferring these procedures. 


Smart contracts, for example, have been one of the most useful consequences of blockchain technology, with a wide range of capabilities. 


As a result, interest in smart contract programming languages has lately increased. 


This article today will be providing you a comprehensive review of the top five programming languages for smart contract development.

1. Solidity 

Solidity is a brand-new and innovative blockchain programming language that has gained traction in recent years. 


Many firms are opting for this programming language because of its ability to create dApps.


The use of Solidity in the development of Ethereum smart contracts is one of the most obvious examples. 


Solidity is a curly-bracket language inspired by JavaScript, C++, and Python. It's based on contracts. As a result, smart contracts are in charge of storing all of the blockchain's logic. 


For all of the above reasons, it is now considered one of the best blockchain programming languages.


Key features:

Solidity is a developer-friendly platform.

Solidity may be used to design smart contracts on other platforms, such as Monax, Ethereum.

Programming that is statically typed.

Possible inheritance attributes in smart contracts,

It provides you with pinpoint accuracy.


2. Java

One of the most popular blockchain programming languages for smart contracts is Java. It's standard programming, and it's used to create a wide range of apps and games.


Because Java is so widely used, it is found in practically all web systems in some form or another, allowing programmers to focus on app logic rather than integration. 


Java provides a dynamic, lightweight, object-oriented programming language. On the NEO blockchain, smart contracts are written in JavaScript.


The language is derived from C-syntax and is popular for developing sophisticated smart contracts and decentralized applications due to the following features:


Key feature: 

The OOP (Object-Oriented Programming) technique is well supported in Java.

The memory-cleaning facility.

Extensive library resources are available.

3. Vyper 

Vyper is a pythonic contract-oriented programming language that targets the Ethereum Virtual Machine (EVM). It's a smart contract-specific programming language with a strong Python flavor.


Vyper aims to increase the security and auditability of smart contracts by reducing dangerous practices and improving readability over Solidity, another Ethereum smart contract language. 


Vyper's core design concepts and aims form a solid basis for smart contract development efficiency. Vyper's design is guided by three principles: Security, auditability, and ease of use


Key features:

Checking for limits and overflow

Signed integers and decimal fixed-point numbers are also supported.


Typing ability

Compiler code that is simple and easy to comprehend

Pure functions have little support.


4. C++

C++ is one of the most popular programming languages for blockchain development.


C++ is a great choice when you require total control over your system resources because it's simple to manage blocks and chains using it.


This language makes it simple to manipulate the blocks and chains of a blockchain. 


C++ is also very adaptable; it gives you complete control over how much CPU and memory you need.


Any language that can compile into WebAssembly (WASM) will be able to build smart contracts on the EOS blockchain, as it uses the WebAssembly virtual engine.


Key features:

C++ provides good memory management and CPU management.

It allows you to transfer semantics for more efficient data copying.

C++ assists you to isolate code for various data structures.


5. Python 

Blockchain Programming Python has not only dominated app development, IoT app development, and network server development, but it is also proving to be a valuable asset in the Blockchain-as-a-Service arena. 


It also provides open-source tools and frameworks with libraries like Numba, which speeds up programming without losing security or performance.


Python's simplicity allows developers to quickly prototype and test new ideas, and its open-source support provides a wealth of tools to aid developers in completing a variety of jobs.


Key features:

It is simple to learn blockchain programming in Python.

Dynamic architecture is accessible.

Open-source support is ideal for both basic and scripting methods.

For prototyping, blockchain scripting in Python is useful.



Each of the five programming languages suggested for smart contracts has its own set of benefits. The idea is that picking the correct programming language for writing smart contracts boils down to selecting the right tool for the job while also fulfilling your own tastes.
