For instance, in the supply chain, blockchain’s unprecedented degree of connectivity helps manage and track millions of products and shipping containers across the globe. Given the fast development of trade, blockchain is extremely valuable for facilitating data transfer among suppliers, manufacturers, shippers, logistic companies, customers, and other stakeholders. Thus, no matter what interests you have or what business goals you pursue, knowledge of programming languages required for blockchain is crucial for designing efficient blockchain-based systems.

Best Programming Languages for Blockchain Development

Since you already know the processes underpinning blockchain’s work, it’s time to discuss the programming languages used for blockchain. These programming languages are very similar to those employed in non-blockchain programs. The only difference is that they presuppose specific methods needed for blockchain creation. Another thing to remember is that the usual programming languages can also be employed to build blockchain systems. So, what are the top five blockchain programming languages

Top 1. Solidity

Created for designing smart contracts, this programming language has been earning increasing attention recently. It was built by the creators of Ethereum – one of the most popular technologies facilitating online payments with cryptocurrency. Therefore, Solidity is specifically adjusted to align with the Ethereum blockchain. The main benefit of this programming language is that it is similar to JavaScript, ECMA-262, Powershell, and C++, which makes it easy for developers to master it. The developer-friendliness is accompanied by flexible language and straightforward instructions, making Solidity an appropriate solution for blockchain development. Other advantages of this language include the following:

  • Support of inheritance features in constructions 
  • Support of hierarchical imaging
  • The use of member variables in classes and objects
  • The use of ABI

However, some may perceive Solidity as less applicable compared to other programming languages such as JavaScript. The problem is that Solidity is used for building blockchain only, while JavaScript is universal and can also be applied in other spheres. Nevertheless, this limitation does not prevent thousands of developers from using this blockchain technology programming language.

Top 2. JavaScript

JavaScript is another popular programming language for blockchain. Its primary sphere of application is app and game development, but it’s also highly valuable for blockchain coders because of the following: 

  • Easier and faster time-to-market.
  • Scalable dApp development.
  • Simple integrations.
  • Cross-blockchain app design.

Top 3. Java

Java is a common programming language used in blockchain. It is an official language for Android coding and is optimal for back-end development tasks. Besides, it is widely popular among blockchain programmers due to the use of C-syntax, smart contract development tools, and dApp creation functionality. Java allows simple memory cleaning, gives access to a broad array of libraries, and supports OOP. Thus, it laid the basis for many well-established blockchains, like IOTA, NEO, and Hyperledger Fabric.
