The Top 7 Programming Languages Used For Blockchain Development

The hype surrounding blockchain know-how is virtually unavoidable today — and whether or not you’re totally on board with the ethos of decentralized software program or stay skeptical about Web3, you is perhaps questioning what kind of tech abilities and programming languages shall be beneficial within the new “Wild West” of the web.

The excellent news is numerous coding languages that you just already know can be utilized in blockchain growth (extra on that later). And even the newer languages which might be particular to good contracts, the important constructing blocks of the programmable blockchain, are comparatively simple to choose up when you have some primary coding information.

However earlier than you begin studying a language, it’s best to perform a little analysis and determine which blockchain platform pursuits you essentially the most, says Kenny Rogers, Developer Advocate on the Stacks Basis. “There are tons of them proper now, which is type of overwhelming,” Kenny says. “They usually all declare to be doing various things the finest means.”

For instance, perhaps your Twitter feed is stuffed with Ethereum information, otherwise you hold seeing job listings for Web3 builders who know Solana. When you slender down which blockchain platform to give attention to, you’ll be able to dig in and see the particular programming languages they use.

In our free course Introduction to Blockchain and Crypto, inbuilt partnership with the Stacks Basis, you’ll find out about completely different chains and their sensible use instances, and stroll away with an goal, high-level understanding of blockchain growth. Listed here are the programming languages which might be used essentially the most in blockchain growth, and what you might want to learn about every of them.


Solidity is essentially the most generally used language for writing and deploying good contracts on the Ethereum chain. It’s a statically typed curly-braces programming language that has acquainted options that you just may acknowledge from different languages.

“Solidity appears to be like fairly high-level however remains to be very near the [Ethereum Virtual Machine],” Christian Reitwiessner, creator of Solidity, mentioned in a 2020 interview. “On the identical time, folks with some background in programming normally perceive what Solidity code is about.”

Solidity’s most important influences are JavaScript, C++, and Python. In case you have a stable (sorry) understanding of these languages, then selecting up Solidity is comparatively simple. Try our course catalog for programs on JavaScript, C++, and Python (in addition to our new Intro to Blockchain course).  


Identified for its velocity and effectivity, C++ is a robust object-oriented programming language that incessantly comes up in Web3. (Enjoyable reality: Bitcoin was written in C++, which C++ creator Bjarne Stroustrup was not thrilled about.) C++ can be utilized for good contract growth on the EOS blockchain.

After all, there are lots of different causes to study C++ that aren’t immediately associated to the blockchain. C++ is a general-purpose language that may reliably run giant software program infrastructure and purposes on few assets, making it the go-to for performance-critical purposes. C++ is used for every thing from gaming to monetary software program to AR/VR purposes.

Be taught one of many world’s most generally used programming languages with our beginner-friendly course Be taught C++. For those who’re already accustomed to the basics of coding, or want a C++ syntax refresher, take a look at our C++ for Programmers course.


Rust is constantly ranked the most-loved programming language in Stack Overflow’s developer survey, with 87% of devs saying they wish to hold utilizing it. One motive why Rust is beloved is as a result of it’s type- and memory-safe, and people security options are why it’s most popular for blockchain growth. Rust is used to construct good contracts on chains like Solana and NEAR.

“If you recognize Rust, relying on the blockchain that you just select to work in, you’ll be able to very probably meaningfully contribute each to the blockchain work itself and in addition good contract growth,” Kenny says. Wish to study Rust? Preserve a watch out for our new course Rust for Programmers, launching quickly.


Excellent news for JavaScript followers: “For each Web3 and Internet 2.0, JavaScript is the primary factor to study if you do not know it already,” Kenny says. For those who initially realized JavaScript to construct web sites and apps, that information can nonetheless serve you within the Web3 and blockchain house. (And for those who haven’t dabbled with JavaScript but, we have now numerous JavaScript programs at each degree so that you can discover.)

Let’s say you’re a Entrance-Finish Engineer who builds an app with JavaScript. You can also make your software work together with present good contracts or the blockchain itself without having to study one other language from scratch. NEAR, for instance, is a well-liked protocol that’s arrange so builders can write good contracts proper in JavaScript or Rust, Kenny says. “You may get actually far simply with JavaScript, after which type of department into these different languages relying on what your targets are and what chain you wish to work in,” he says.


This newer good contract language is particular to the Stacks blockchain and has a number of distinctive options and guardrails that make it particularly safe.

For starters, Readability is decidable, which implies there’s a finite variety of steps for each enter and you recognize the place the code will terminate. Readability doesn’t allow looping, and it’s purposefully “Turing incomplete,” so that you might be sure {that a} program execution will finish in some unspecified time in the future, eliminating the chance of a halting drawback — a beneficial property to have in an immutable, globally-distributed system. The language additionally prohibits reentrancy, which is when one good contract calls into one other after which calls again into the primary contract — a scenario that may expose contracts to assaults.

Another excuse why it’s best to take into account testing Readability? Kenny says there’s a hiring demand for Builders who know Readability. “We’re at this bizarre level the place there aren’t quite a lot of Readability builders, so there’s type of a scarcity proper now,” he says.


Google’s statically-typed open-source language Go (or “Golang”) is usually used for back-end growth and creating high-performance purposes. ​​Geth, quick for “Go-Ethereum,” is an Ethereum consumer that’s written in Go.

In comparison with different languages, Go is quick and lean, and means that you can multitask working a number of processes with out sacrificing reminiscence assets. With Go, you’ll be able to construct purposes from its sturdy library of capabilities and packages. Our course Be taught Go is a beginner-friendly introduction to Google’s programming language, and can have you establishing a Go surroundings and making a Go file immediately.


Numerous individuals are followers of Python’s English-like syntax and cross-platform versatility, and the general-purpose language will also be used for blockchain growth. For those who’ve by no means picked up Python earlier than, we have now numerous beginner-friendly Python programs to select from, it doesn’t matter what your targets are.

Prepared to offer blockchain growth an opportunity? Attempt our free course Introduction to Blockchain and Crypto for a language-agnostic overview of the world of crypto and its underlying know-how, inbuilt partnership with Stacks Basis.

C++ is a highly regarded language for performance-critical purposes that depend on velocity and environment friendly reminiscence administration. It’s utilized in a variety of industries together with software program and recreation growth, VR, robotics, and scientific computing.
