Blockchain technology is still in a nascent stage of development however this disruptive technology has managed to take the world by storm and experienced a boom like no other since the inception of Bitcoin.

With many well-funded projects now eager to develop decentralized applications and to follow through on their technical roadmaps there is a great shortage of capable and competent developers when startups seek to recruit new talent

With billions invested & funneled into this sector, the demand for blockchain developers has escalated with projects bidding and vying to attract the best blockchain talent despite the shortage. With billions of dollars raised through countless Initial Coin Offerings (ICOs), projects have been busy head hunting around the block for developers eager to accelerate their rate of progress.

This gold rush may leave some developers wondering if they have what it takes to dive into this industry and wondering what programming languages are most sought after in this particular sector. There are numerous programming languages used in the blockchain industry however developers must consider the type of languages that are in demand and preferred by projects.

Here’s a brief rundown of different projects and the preferred programming languages needed to begin develop decentralized applications & services.

Solidity
A new and simple programming language that is popular amongst Ethereum developers as it’s the preferred language used for executing Ethereum smart contracts. Solidity is a contract-oriented & turing-complete programming language designed specifically for writing smart contracts. It is recommend to learn Solidity due the sheer popularity of the programming language in the blockchain industry, thus Developers are assured that they will be able of execute a wide-variety of smart contracts on various blockchain platforms that support the language.

Ethereum – Technically, the Ethereum Virtual Machine (EVM) which can be thought of as a “world computer” is made up of multiple languages including C++, Python, Ruby, Go, and Java. JavaScript serves as the backbone of Ethereum as it functions a runtime environment capable of script execution however Solidity is currently the main programming language used to execute & run smart contracts.

Javascript
Often abbreviated as JS, is considered a multi-paradigm language since it supports event-driven, functional, and imperative (including object-oriented and prototype-based) programming styles. Launched in 1995, Javascript is known for being the preferred programming language of HTML and the web

Lisk’s – SideChain Development Kit (SDK) is written in JavaScript and allow developers to build applications on top of Lisk’s blockchain platform. The platform will make it easy for developer to build & deployed applications written in JavaScript.

Java
A general-purpose programming language that is concurrent, object-oriented, and class-based is designed in such a way that Java has few implementation dependencies. Since its launch in 1995, Java has become one of the top 3 programming language

-NEM’s blockchain core has been written in Java (soon to be C++).

C#
An object-oriented language known to enable developers to build robust applications that run on the .NET Framework. Pronounced as ‘’C-sharp’’, C# was developed back in 2000 and since its inception has become a popular programming language used to build powerful cross platform code that work over multiple operating systems such as Windows, Mac, Linux, and Android.

-Stratis a Blockchain-as-a-Service provider backed by Microsoft, allow enterprises to build their own private blockchain systems.

-NEO was written in C# however it also supports a variety of programming languages such as Javascript, Java, Python, and Go.

C++
A general-purpose programming language C++’s greatest strength is the capability to scale allowing applications that are resource intensive to run smoothly, thus making it a popular programing language for running 3D games.

EOS – C++ is the main programming language of EOS prefered for its flexibility to run extensive applications on top of the blockchain. EOS also supports any language that compiles into WebAssembly (WASM)

Random Fact: Did you know that Bitcoin core programming is written in C++

SQL
Structured Query Language or ‘’Sequel’’ is a programming language developed by IBM and is used to communicate with databases that store, query, and manipulate data. Popular databases such as MySQL, PostgreSQL, SQL Server, DB2, Oracle and more all use SQL to develop applications.

Aergo – An upcoming entreprise-ready blockchain solution built using Coinstack the proprietary software developed by Blocko. AergoSQL, a new smart contract engine for Blockchain will allow developers to run smart contracts written in SQL. The Aergo chain features a SQL-based smart contract platform that will allow enterprise to easily create and deploy advanced smart contracts on top of a hybrid blockchain.

Golang
An open source general programming language that is loosely based on the syntax of the C programming language. Golang is known for being a compiled language that is relatively easy for developers to learn and for testers to understand

HyperLedger Fabric – Most of the chaincode (smart contracts built using HyperLedger Fabric’s) is written in Golang. HyperLedger Fabric also have a Java SDK for developing blockchain applications.
