Top Programming Languages for Making Blockchain Apps

by Fahad Saleem

Blockchain is a chain of sequentially connected blocks using cryptographic logic. Due to high-level security it provides in business transactions, this technology is used heavily in industry and blockchain developers are sought everywhere equally. Here in this article, we have outlined a list of the best blockchain programming languages.

Based on a survey done by Hard Fork who searched StackOverFlow for entries tagged with the term “blockchain”, Solidity takes the top spot. Out of total 2,724 questions, Solidity was answered 259 times. JavaScript takes the second spot, followed by Java. JavaScript was mentioned 130 times in questions and Java with 71 mentions. Following graph shows the 10 popular blockchain programming languages:

It is a contract-oriented Turing-complete programming language that is used for developing Ethereum smart contracts and making DAPPs (Decentralized Applications) or getting into ICO game. The number of developers of this language is estimated at over 200,000. Solidity is a purposefully slimmed down, loosely-typed language with a syntax similar to that of JavaScript. Many blockchain platforms are ensuring that they are Solidity compatible, thus allowing smart contracts to be ported easily from Ethereum into their new blockchain networks. Solidity is the focus of many blockchain courses available, and so anyone looking to develop their skills and understanding of this language can do so by participating in a coding bootcamp.


This language is a multi-paradigm that supports event-driven, functional, and imperative programming styles. It is used by at least 9.7 million developers globally. Lisk’s SideChain Development Kit (SDK) is written in JS that allows the developers to build applications on top of Lisk’s blockchain platform. The main advantage of using this language is that it is already installed on most systems and every web system utilizes it in one way or another. This language is used to create highly interactive webpages.


It is a concurrent, object-oriented, and class-based general-purpose programming language having few implementation dependencies. It has over 9 million developers globally. NEM’s core blockchain network is written in Java. The main reason behind the use of Java as the de-facto blockchain programming language in the industry is its highly-capable portability. Programs written are portable across any computational device, since they don’t rely on system-specific architecture, instead use JVM for execution.


Python is a simple and minimal programming language. The simplicity is due to the white spaces to signify the code blocks instead of curly brackets or keywords. This language can turn out to be the best blockchain programming language if you are a new developer. It gives developers the ability to prototype their ideas quickly. It also enables developers to write programs in an object-oriented approach, which can be utilized to cope with many of its performance related overheads.


It is an open source general programming language that is loosely based on the syntax of the C programming language. Currently, there are 800,000+ developers of this language that is used by the consortium network. It is on par the performance level needed by a blockchain coding language. It comes with every advanced feature required for building blockchain.


Along with major technologies used in the industry, C++ is superior even in the blockchain technology. The first ever implementation – Bitcoin, was initially written in this ultra-precise and powerful language. It is used by approximately 4.4 million developers. It has the capability to scale resource intensive applications and enable them to run smoothly.
