Blockchain Technology is currently the hottest technology in the world. Enterprises from all over the world are thrilled about the concept of decentralized exchange of value and storage of transactional records. Blockchain has revolutionized various industries such as supply chain management, cross-border payments, voting, and tracking royalties. It has also given birth to new sectors such as Decentralized Finance(DeFi), NFT marketplaces etc.

Blockchain tech is still at an early stage. Developers from the entire world are experimenting and speculating its capabilities and new projects are rolling out every day. Businesses are adopting blockchain tech to improve their current efficiency, and security and build new features.

All this hype around this technology has led to a massive requirement and a dramatic rise in the pay grade of skilled blockchain developers.

Types of blockchain developers

1. Core blockchain developers

Core blockchain developers are responsible for developing the architecture of blockchain systems. This includes many factors such as choosing a proper consensus mechanism, selecting the appropriate second layer scaling solution, designing the test networks, support for cryptocurrencies etc. In layman's terms, they don't build dapps on the blockchain, they build the blockchain itself.

2. Blockchain software developers

These developers are primarily full-stack or backend developers who also possess blockchain skills. They use the protocols designed by the core blockchain developers to build apps on the blockchain. These apps are also known as dapps (decentralised apps). Currently, the most popular blockchain for dapp development is Ethereum.

So if you want to become a highly-paid blockchain developer here is a list of programming languages you should start learning.

Note: You don't need to learn all the languages listed here.

1. Javascript

Javascript is regarded as the king of web development. It is one of the core technologies of the world wide web. Javascript used to be the go-to language for client-side web applications, but thanks to nodejs today we can run javascript on the server side to create highly scalable web applications.

The biggest advantage javascript offers for developers is that they don't need to learn different languages for frontend and backend tasks. This makes JavaScript the most prominent developer-friendly programming language. Today, Javascript is not only used for web development but also Mobile development, IoT and even AI.

Javascript handles asynchronous tasks efficiently. It allows asynchronous parallel programming which is the key requirement for a blockchain app. Using Javascript we can build blockchain solutions for the web, mobile or IoT. This is the reason why most of the prominent dapp development platforms such as Ethereum and Hyperledger have a NodeJs SDK.

2. Go

Go is a great programming language for blockchain development. Golang shines in any kind of network-related task. Whether it's writing server code for the backend or designing new network protocols. Go's biggest advantage is its simplicity and ultra-fast execution speed.

Go is suitable for both Dapp development and Core blockchain development. It is also primarily used for building decentralized systems.

Parts of Ethereum and Hyperledger have been developed with Go. These platforms also provide Go SDK for dapp development.

3. Rust

Rust is a great programming language for Core blockchain development. Rust is superfast and memory safe. With rust, you make a lot fewer errors. Any code which is not memory safe will not compile in Rust.

These features make Rust a great choice for architecting blockchain solutions such as designing new consensus protocols etc.

Substrate is a technology that makes it easy to build industry-standard blockchain solutions. Substrate uses rust for development purposes. It uses WebAssembly smart contracts.

4. Solidity

Solidity was created for writing smart contracts that run on Ethereum virtual machine (EVM). Since solidity was created by keeping blockchains in mind, it contains all the tools required for developing your blockchain application.

5. Java

Java is a popular object-oriented programming language. Java is fast, platform-independent and statically typed language. You can write java code on one platform and run it on any platform with the help of Java virtual machine(JVM). All these features make java a suitable language for blockchain development.


There are many more programming languages that have their pros and cons and can be used for blockchain development. Here we have covered languages that will help you cover most of the aspects of the blockchain development lifecycle. However, choosing the best language depends upon the requirement of the project and the familiarity of the developer with the language.
