Unless you are living under the rocks, it is likely that you would be familiar with what is Blockchain and what is its potential when it comes to reforming the tech world. 

The technology, that have been the driving force of Cryptocurrencies, has taken the front seat and come up with a myriad of options to mitigate the traditional challenges that a myriad of industries face, helping them grab better opportunities. It has proven to hold the potential to revamp the whole economy – be it healthcare, travel, education, or legal domain.

A ripple impact of which is that today, both startups and Fortune 500 companies like IBM, and Accenture are putting efforts towards making their presence known in the Blockchain arena. 

Because of this, rather sudden, mass adoption, the number of Blockchain jobs are increasing in the market exponentially. A clear indication of which is that a 517% rise is predicted in the number of Blockchain jobs in 2019, compared to 2018.

And, behind the curtains, the tech stack – the type of platforms and blockchain programming languages are also evolving. While many traditional ones are proving to be undisputed leaders, many new entrants are bringing radical changes in the development environment.

This, as a whole, is making it necessary for all Blockchain enthusiasts to be familiar with the best Blockchain programming languages to headstart with. Something we will cover in this article. 

But, before that, you will be able to earn brownie points if to go through a Blockchain development guide to have a clarity of concepts, and to get familiar with the challenges developers come across while starting their journey in  this innovative technology.

Challenges You Might Face While Entering the Blockchain Development World

A. Resource Management

In the Blockchain arena, it is imperative for developers to ensure that they are familiar with real-time network demands and that they are well-versed with opportunities to handle remote and local queries. This, in turn, can be challenging for them to manage their resources efficiently and effectively.

B. Isolation

Another issue faced by Blockchain developers is that all the hash functions operate in a deterministic manner. Meaning, they do not act in two different ways depending on the circumstances.

In such a scenario, the development team has to opt Isolation mechanism to bring non-deterministic nature into their blockchain solution.

C. Lower Performance

Last but not least, Lower performance is also one of the challenges of Blockchain programming that developers often have to deal with. Especially when choosing the right Blockchain development language

This is because some of the Blockchain operations are parallelizable, while others are not. Meaning, it becomes important for them to bring a language on table that is versatile in nature.

Now that you know what Blockchain programming problems you might encounter while heading your journey to Blockchain development, let’s jump to the core part of this article, i.e, unveiling of the top Blockchain programming languages.

15 Programming Languages to Consider for Developing Blockchain Applications

1. Solidity

Solidity

Influenced from JavaScript, Powershell, and C++, Solidity is the first blockchain programming language that one must learn. Especially when they have to develop dApps or are looking to get into the ICO development game.

4. JavaScript

JavaScript

Considered for a wide range of app and game development needs, JavaScript is also one of the best Blockchain programming languages to keep an eye on.

The language, in the form of frameworks like Node.js framework, offers developers ample of benefits like:-

  • Easier and earlier entry to market,
  • Enhanced Scalability, 
  • Availability of multiple JavaScript frameworks
  • No hassle of integration of respective resources, and more.

5. PHP

PHP

Released in 1995, PHP (Hypertext Preprocessor) is another programming language that every reputed mobile app development company recommend for creating Blockchain solutions. 

The language, though considered as a backend development tech stack in the form of best PHP frameworks, is often used to develop blockchain solutions of different complexity range. Something that is a ripple effect of its huge open-source community and object-oriented features.

6. C++

 C++

C++, introduced back in 1985 by Bjarne Stroustrup, is the best programming language for cryptocurrency development. 

The language follows OOPs methodology and is highly used for developing cryptocurrencies and Blockchain Projects like Bitcoin, Litecoin, Ripple, Stellar, and EOS. Something that is a direct result of the following set of features and functionalities it offers:-

    1. Efficient CPU management and memory control,
    2. Ease of running parallel/non-parallel threads,
    3. Option to move semantics for copying data effectively, 
    4. Compile-time polymorphism for enhanced performance, 
    5. Code isolation for different data structures, and more.

7. C#

C#

Created by Microsoft as a substitute of Java, the OOP language offer a huge number of features for enterprise-powered apps, cloud, and cross-platform development. The language comes loaded with features of C, SQL, and .NET frameworks, and is highly favored for Blockchain development because:-

    1. It is open source.
    2. Its syntax is easy to understand and learn – thanks to its identicality with C++ and Java.
    3. It empowers developers to write portable code across devices.
    4. It is cost-effective to use because of BizSpark program.

The programming language is majorly considered for building dApps, Smart Contracts, and infrastructure in Blockchain environment.
