Prominent Blockchain Programming Languages to consider while
building Blockchain Apps!
Blockchain has become a buzzword in today’s tech world. This technology has successfully
resolved the traditional roadblocks existent in certain industrial domains by decentralizing data
and opening up new avenues of security and transparency.
Blockchain records digital information in a manner that the information can be recorded and
distributed, but not altered. Hence, Blockchain is used to form immutable ledgers and records or
transactions that cannot be hacked, modified, or destroyed. Blockchain applications are
employed for demanding tasks like the exchange of cryptocurrencies, the secure sharing of
medical data, voting mechanism, NFT marketplaces, making/receiving cross-border payments,
monitoring supply chain/logistics, and many more.
However, developing such solutions is not an easy task, and businesses planning to adopt
Blockchain systems must be aware of the ins and outs of Blockchain development. One of the
crucial considerations for creating Blockchain solutions is the programming language stack chosen
for development. And, needless to say, the programming language should be chosen as per the
project requirements. This post explores the offerings of the top Blockchain programming
languages with examples of use cases. The write-up will provide a clear idea and help you to pick
the most suitable language stack for your upcoming Blockchain project.
Blockchain Functioning: In a Nutshell
The Blockchain system comprises a digital ledger of transactions. Each block within the chain

contains a certain number of transactions and whenever a new transaction takes place on the
blockchain network, the transaction record is added to each participant’s ledger. This
decentralized database is called DLT (Distributed Ledger Technology) and is managed by multiple
participants.
Top Blockchain Programming Languages
Solidity
Solidity was created by the Ethereum team in 2014 for writing Ethereum-based smart contracts,
to enhance the usability of Blockchain solutions. With Solidity, developers were able to write a
high-level code that is smart-contract oriented and that could be translated into the usable lower-
level languages prevalent at that time. The language resembles the ECMAScript syntax but
contains features such as static typing, variadic return types, and so on. And hence, it is one of the
most preferred programming languages used for Blockchain projects and recommended by most
Blockchain app developers around the world.
This statically typed Blockchain language offers a stable and flexible coding pattern for smart
contracts and provides an accurate as well as a safe medium where different sources can frame
smart contracts between parties. Moreover, it is a flexible and user-friendly language that comes
with ABI (Application Binary Interface) that provides several type-safe functions. Developers can
effortlessly acquire the necessary skills needed to use Solidity, whether they are experienced ones
or simply beginners.
Blockchain Project Use Cases: Ethereum, Chainlink, Sushiswap, and Compound Protocol.

C++
This object-oriented language is one of the key Blockchain programming languages. C++ was
created to code the decentralized cryptocurrency system and developers employed it to code
bitcoins. But today, it suits the purpose of other Blockchain-based projects and has been used for
storing transaction information in cryptocurrencies like Ripple’s XRP Ledger, Ethereum’s smart
contracts, etc.
C++ is easy to use and flexible; and comes with abilities like advanced multi-threading, primitive
control over memory, and an efficient CPU management capability. It enables one to isolate the
code for various data structures and allows you to move semantics so that data can be copied
effectively. C++ users can control the code as desired – they can choose between providing full
access to the code or allowing access to only certain aspects as per the need. With C++, one can
easily manipulate blocks and chains, and so, is an ideal pick for scenarios where one needs to fully
control their system resources.
Blockchain Project Use Cases: Monero, Ripple, Stellar, EOS, Litecoin.
Python
Python is one of the most popular programming languages used for architecting Blockchain
applications, crypto exchange, and smart contracts. It is a robust, versatile, and object-oriented
programming language that comes with open-source support and also, several frameworks and
libraries such as Numba that accelerate the development without affecting the performance or
security. Python dynamically supports OOP, and hence, facilitates crafting solutions in Blockchain
as well as in Machine Learning and Artificial Intelligence. Using this language, one can easily
detect errors and debug those errors.
Python is particularly helpful for newbie developers working on Blockchain projects as this
language facilitates building prototypes quickly without having to write lengthy codes and the
developers have the option of selecting from a wide range of plugins, libraries, and online
resources.
Python, being an interpreted language creates roadblocks when complicated cryptographic
operations are involved, but this problem can be resolved by the proficiency of experienced
Blockchain app developers.
Blockchain Project Use Cases: Steemit, Ethereum, Hyperledger Fabric, NEO, etc.
GoLang
GoLang, a statically typed, compiled and multi-threaded language created by Google, is one of the
most popular Blockchain programming languages in the NFT marketplace. The language
integrates the best of both worlds – the ease of developing the code and the effectiveness of

compiled language. It combines the features of Java, Python, and C++ and is being used by the
Hyperledger Fabric platform currently. It is user-friendly, fast, flexible, and scalable.
Using GoLang, one can run several processes simultaneously, and therefore, it is can effectively
handle several parts of blockchain simultaneously. GoLang is not only speedy but also offers
accessible maintenance features and so, it’s an ideal pick when a decentralized app is being
distributed on Ethereum’s network. However, it comes with a difficult learning curve but will be
simple for C++ developers.
Blockchain Project Use Cases: Ethereum, Loom Network, Hyperledger Fabric, GoChain, and Dero.
Java
Java is an object-oriented programming language that follows a “write once and follow
everywhere” approach and so, enables one to write codes that are highly portable. With the Java
Virtual Machine (JVM), developers can run their codes on any system or platform. And, as the
universal JVM is used for execution, Java programs need not depend on a system-specific
architecture. This portability of Java facilitates the creation of easy-going and immutable
blockchains. Furthermore, Java comes with an abundant API (Application Programming Interface)
that contains several Java classes, interfaces, packages, etc. This property helps in building apps
without any need to know their internal implementations.
Java offers a simple and extensible plugin architecture that helps to create a flexible Blockchain
solution. Java has a huge and dynamic community that provides prompt and effective solutions to
developers whenever they encounter any issue.
Blockchain Project Use Cases: IOTA, NEO, NEM, Ethereum, Fabric, and Hyperledger.
C#
C# is an open-source programming language coined by Microsoft and enjoys humongous
popularity worldwide. It employs easy Object-Oriented and Extensible Markup methods, without
the developer’s help. Its rich library class simplifies the use of menu functions and implements
them for coding. The assembly feature eases out handling the issue of version control. With C#,
open-source developers can effortlessly write codes that are highly portable and run across
several OS like Mac, Linux, Android, and Windows.
Blockchain Project Use Cases: IOTA, NEO, Blockchain as a Service, and Stratis.
Rholang
Rholang is employed for creating smart contracts and high-grade Blockchain projects. It follows a
functional approach – at first, it examines the application through several functions and

thereafter, solves them as per the sequence. It is secure, reliable, easy to use, and speedy.
LLL (Low-Level-Lisp-like language)
Low-Level-Lisp-like language, commonly known as LLL, is a low-level programming language. LLL
happens to be quite easy-going and minimalistic, it’s just a small-sized wrapper directly placed
over the EVM coding. This is one of the original Ethereum programming languages used for smart
contracts. It offers a different programming discipline and point of view as compared to the
universal Solidity language.
To make it compatible with EVM programming, the Lisp-like code contains a thin layer of
parentheses. So, the LLL users enjoy high-end programming support while accessing various
lower-level sources of power as well as memory locations. Moreover, this language enables
programmers to develop effective contracts that are smaller in size as compared to the ones
created using higher-level languages.
Simplicity
This high-level Blockchain programming language was designed for smart contracts and it caters
to professional programmers as well as open-source developers. This language is relatively new
and reduces the low-level understanding and complicated functionality of the Bitcoin Script.
Simplicity helps Blockchain app developers to enhance productivity and avoid distractions. It
hides low-level components from engineers and developers, resulting in a rapid development
speed.
JavaScript
This popular programming language works for Blockchain development as well because of
Node.js, a runtime environment of JavaScript. The language helps developers to handle
asynchronous code which is the fundamental prerequisite in the Blockchain environment.
Moreover, it enables asynchronous parallel programming due to which the Blockchain program
can complete more than one action simultaneously.
Vyper
This Blockchain programming language is derived from Python3, although it doesn’t contain all
the Python features in it. It was designed as an alternative for the language Solidity and is
primarily employed in EVM (Ethereum Virtual Machine). However, Vyper’s control structures are
different from the ones in Solidity and it handles security issues differently as well. Vyper’s control
structure is distinct and contains features such as modifiers, recursive calling, infinite loops, etc.
Obsidian
Obsidian is one of the newer Blockchain programming languages. It presently functions on the
Hyperledger Fabric platform and the Ethereum Blockchain platform.

Most blockchain programs are organized around a machine having a high-level state and
Obsidian’s state-oriented programming helps one to explicitly declare and transition amongst
states. Obsidian builds a flowchart-like sequence that helps one to view contracts through
different stages. The states and transitions within the states have to be mentioned while coding.
Obsidian offers a linear type system that simplifies the process of implementing a belt to
suspenders. The compiler can make full use of the types for avoiding bug issues or typo-based
errors.
