10 Best Programming Languages for Blockchain in 2022

Blockchain technology is one of the fastest-growing and hottest industries in the world right now, with job and skill requirements only expected to increase over time. 

With that, it’s also important to understand that not all programming languages are equal when creating blockchain platforms, and some perform better than others, depending on your needs. 

If you’re looking to get into programming and learn how to create blockchain applications, this list of the top 10 programming languages for blockchain in 2022 will help you figure out which language(s) you should look into learning first.

1) C++

First released by Bell Labs in 1979, C++ (pronounced C plus) is a general-purpose programming language that supports procedural, object-oriented, and generic programming. 

It is one of the most popular programming languages on Stack Overflow because it offers ample opportunities to use cryptography.

Note: Although you can build simple and complex systems with C++, it requires more experience than other languages discussed here.

2) Java

Java is a very common programming language, and it’s widely popular with blockchain. The benefit of using Java is that a lot of training resources are available, you can use Java’s comprehensive APIs to do tasks more quickly and efficiently than with some other languages, and it has a high-level syntax, so coding can be less repetitive and take less time. 

On top of that, it’s portable, which means you can move code from platform to platform without too much difficulty. The only major downside is that there are situations where you might have trouble finding expert programmers for Java because it’s been here for such a long time now. Still, it seems unlikely that Java will lose popularity anytime soon.

3) Python

With Python being so easy to learn, it’s no wonder why it’s becoming one of the most popular languages for blockchain development. The best part about Python is that one can use it to create both white- and black-box software. 

Furthermore, it’s a dynamic programming language, which means applications can be updated and executed without compiling. This makes Python an ideal option for blockchain developers who want to keep their code as flexible as possible. If you want your code to run on multiple platforms, then look no further than Python.

4) Go

Go is a general-purpose programming language developed by Google. It helps you to make it easy to build simple, reliable, and efficient software. Go helps you solve problems like scaling web applications built on top of large data sets—problems that frequently arise within Google and in countless other software engineering contexts. 

Today Go is one of the most popular languages for writing servers that run HTTP or HTTPS services. This popularity is mainly due to its speed: Go compiles into native machine code and runs very fast. Because of its performance characteristics, Go has become increasingly popular with developers building microservices (small, independent services) that need to be highly responsive. 

In fact, in recent years, many new startups have been founded with microservices architectures at their core; they often use Go as their primary programming language because it allows them to iterate quickly while staying lean.

5) Perl

Perl was one of blockchain’s earliest programming languages, and even though its popularity has fallen slightly over time, it’s still an important language to know. The Syntax is clean and easy to read, making Perl a good choice if you’re looking to make a career out of blockchain development. 

It also has a very active developer community, so plenty of Perl libraries are available on most all blockchain platforms. You can use Perl to create scripts that automate repetitive tasks (which is great news for blockchain developers) and web applications. If you have some knowledge of SQL databases, learning Perl will be a cinch!

6) Ruby

Like most new languages, Ruby was created to fill a niche. In 1995, programmer Yukihiro Matsumoto wanted to create an easy-to-read language that could be used by anyone—even those with no programming experience. 

Today, it’s widely used by startups and big companies, from Pinterest to Netflix. Many big companies are increasingly turning to the best blockchain development company in India and around the globe that can build applications using Ruby. 

This year, IBM partnered with 17 banks to launch what they call the world’s first multilateral trade finance platform built on open standards and designed for enterprise adoption.

7) Swift

Developed by Apple and open-sourced under an Apache 2.0 license, Swift is a fast, general-purpose, multi-paradigm programming language built using a modern approach to safety, performance, and software design patterns. The language takes inspiration from Objective-C, Rust, Haskell, Ruby, Python, and CLU. 

Some notable features of Swift include its advanced error handling model, type inference, focus on interoperability with C/Objective-C codebases, and support for functional programming concepts like closures and first-class functions.

8) Scala

Scala is a general-purpose programming language, and it’s popular among some of Silicon Valley’s biggest companies to power their high-growth businesses. 

But unlike most curly brace languages, Scala is an object-oriented language—that means it provides users with an opportunity to get closer to bare metal when they need to. In fact, one of its creators likes to say that Scala runs on Java but loves Python. 

For developers looking to create applications that run on distributed ledgers or blockchain platforms (like Ethereum), Scala could be a good choice because it supports functional programming while still allowing developers to leverage existing Java libraries and frameworks. It also supports concurrent processing well, making it great for applications that process data asynchronously over networks.

9) Haskell

Haskell is a general-purpose programming language with non-strict semantics, named after logician Haskell Curry. 

The language is statically typed, but with lazy evaluation, a form of non-strict typing where expressions are only evaluated when their value is needed rather than before they’re defined. 

This allows programs to be written in an imperative style while enforcing minimal evaluation. For example, without laziness, it would be impossible to write infinite lists (such as streams) or functions that produce infinite streams (such as replicates). 

Haskell also supports functional programming with higher-order functions and type classes. These features make it popular among some researchers who work on advanced algorithms.

10) Rust

Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. Mozilla created it in 2011 to build high-performance applications that run inside browsers and other resource-constrained environments. 

It’s now seeing increasing use outside its web browser niche, including an upcoming blockchain toolset from Kraken Exchange. 

By default, Rust doesn’t allow its users to access uninitialized memory (like C), which can prevent bugs common in C++ development. This makes it easier to write safer code without needing as much time and effort on error checking.

Deciding on which programming language to use when developing a blockchain can be difficult, and it can be even more confusing when there are multiple options. Ultimately, you’ll want to choose a language that aligns with your technical experience, goals, and timeline. 

C++ and Java are currently the go-to choices for most blockchain development companies due to their widespread adoption. However, if you’re looking to hire blockchain developers in India or elsewhere, keep an eye out for emerging languages like Haskell and Rust. 

As blockchain technology continues to grow, so will its supporting ecosystem of tools and languages—so it pays to stay ahead of the curve!
