Top 15 Programming Languages  for Blockchain Development

1. Solidity


Influenced by JavaScript, Powershell, and C++, Solidity is the first blockchain programming language that one must learn. Especially when you want to develop dApps or are looking to get into the ICO development game.

The Solidity blockchain programming language was developed by Vitalik Buterin, the mastermind behind Ethereum. It serves blockchain development firms with a myriad of benefits, such as:-

  • Developer-friendliness,
  •  Accessibility to JavaScript infrastructures, debuggers, and other tools, 
  •  Statically typed programming,
  • Possibility of inheritance properties in smart contracts,
  • Precise accuracy

2. Java


Java, the official language of Android mobile app development and a preferred option for backend development, is also considered one of the top blockchain programming languages used for Blockchain development.

The language is derived from C-syntax and is widely chosen for building sophisticated smart contracts and dApps because of its following properties:-

  • Robust support for OOP (Object-Oriented Programming) methodology,
  • Ease of memory cleaning
  • Availability of ample libraries

Some of the best examples of Blockchain solutions developed using Java are NEM, IOTA, NEO, and Hyperledger Fabric.

Steem, Hyperledger Fabric, and NEO are a few popular Pythonbased Blockchain projects that are prevailing in the industry.

4. JavaScript


Considered for a wide range of app and game development needs, JavaScript is also one of the best Blockchain programming languages to keep an eye on.

The language, in the form of frameworks like Node.js framework, offers innumerable benefits to developers, such as:

  • Blockchain programming with javascript enables easier and earlier entry to market
  • Blockchain programming with javascript enhances scalability
  • Availability of multiple Blockchain JavaScript frameworks
  • No hassle of integration of respective resources, and more

5. PHP


Released in 1995, PHP (Hypertext Preprocessor) is another programming language used for blochain development that every reputed mobile app development company recommends for creating Blockchain solutions. 

PHP is often used to develop blockchain solutions of different complexity ranges. Something that is a ripple effect of its huge open-source community and object-oriented features.

6. C++


C++, introduced back in 1985 by Bjarne Stroustrup, is the best programming language for cryptocurrency development. 

The language follows OOPs methodology and is highly used for developing cryptocurrencies like Bitcoin, Litecoin, Ripple, Stellar, and EOS. Some of the prominent features and functionalities oF C++ are: 

  • Efficient CPU management and memory control
  • Ease of running parallel/non-parallel threads
  • Option to move semantics for copying data effectively
  • Compile-time polymorphism for enhanced performance 
  • Code isolation for different data structures, and more

7. C#


Created by Microsoft as a substitute of Blockchain coding Java, the OOP language offers a huge number of features for enterprise-powered apps, cloud, and cross-platform development. The language comes loaded with features of C, SQL, and .NET frameworks, and is highly favored for Blockchain development because: 

  • It is open source.
  • Its syntax is easy to understand and learn – thanks to its identicality with C++ and Blockchain coding Java.
  • It empowers blockchain app developers to write portable code across devices.
  •  It is cost-effective to use because of the BizSpark program.

The programming language is majorly considered for building dApps, Smart Contracts, and infrastructure in a Blockchain environment.

8. Go


Go programming language also lands in the list of top Blockchain coding languages with a blistering success. 

The language is not just easy to comprehend, but also comes with the best features of JavaScript and Python such as user-friendliness, scalability, flexibility, and speed. Something that makes it the right option to deliver bespoke Blockchain solutions.

Two of the best Go-based Blockchain solutions prevalent in the market are Go-Ethereum and Hyperledger Fabric.

9. Simplicity

Created by Russell O’ Connor, Simplicity is one of the high-level Blockchain coding languages that hit the market in November 2017.

 The Simplicity programming language is based on Ivy and works with a Haskell-like syntax which makes coding easier and effective. Besides, it is highly mathematical in nature and makes the codeline human-readable. Because of which, it is highly used for developing Smart Contracts and blockchain solutions that works with both Bitcoin and Ethereum Virtual Machine (EVM).

10. Ruby


Ruby is the best language for blockchain development to headstart your career with.

Developed by Yukihiro “Matz” in the mid-1990s, this high-level and general purpose programming language empowers blockchain developers to prototype their vision effectively and effortlessly through open-source third party APIs and plugins. The language also gives developers an opportunity to mix its features with that of other languages to build an enhanced platform.

It is highly considered by Asian developers for building Blockchain-based software and platforms.

11. Rust


Though a newbie in the Blockchain ecosystem, Rust is also being widely considered for building innovative, immutable, and secure solutions. 

The language enables open-source blockchain developers to create quick and effective frameworks. It also serves them with a highly-capable mechanism of managing mutable states, amazing code optimization, better memory options, and concurrency-based opportunities.

12. SQL


SQL (Structured Query Language) is also one of the top blockchain technology programming languages to consider in 2022. 

The language was designed by IBM to make communication with databases like MySQL, SQL Server, PostgreSQl, and Oracle easier and efficient. It is used for building secure and effective enterprise solutions in the Blockchain domain. A clear evidence of which is Aergo.

13. Erlang


Erlang is another top Blockchain coding language you must consider for a brighter future ahead. 

The language, though less popular than reputed names like blockchain programming Java, JavaScript, and Python, serves Blockchain development companies with options like: 

  • Unparalleled backend facility
