Blockchain is not new these days. This technology has long been featured in the media in Vietnam and around the world. Global investment in blockchain technology is expected to reach a whopping $ 15.9 billion by 2023, according to Developers Stats. Blockchain technology is considered the most devastating technology in 2020, shortly after artificial intelligence and machine learning. Indeed, blockchain is a disruptive technology, with innovative applications used in a variety of areas such as cross-border payments, healthcare, time sites, and agriculture. However, Bitcoin is still the best-known example of blockchain technology.

As a developer, are you probably wondering which top programming language is best for blockchain development? If you want to be a blockchain developer, you need to be familiar with the most popular programming languages in this technology. Each language has its strengths and weaknesses, and it also affects the functionality of the blockchain. Depending on your interests and the area in which you work, choose a language to learn more about blockchain applications or the next step.

Use of language in blockchain programming

Certain blockchain networks can use and implement a variety of programming languages. This is in stark contrast to the typical closed-source, centralized proprietary network that companies develop for their internal use. These enterprise networks are often written and updated in one language and rarely contain code written in another language.

The public blockchain is open source and decentralized, so it does not necessarily show such uniformity. For example, Ethereum blockchain is developed in various languages such as Go, Java and Python.

Talking about the major languages used in the blockchain, we can see that many different languages are associated with the same platform, although the purpose of the application is different.

7 popular programming languages for blockchain development

1. C++

C ++ is one of the most popular programming languages in the world and has become mainstream in the blockchain industry. In addition to its usefulness as a language in blockchain development, it shares the same principles as blockchain. These principles include polymorphism, data hiding, abstraction, and encapsulation to prevent data changes.

Bitcoin, the first blockchain implementation, was originally written in C ++. An excellent blockchain programming language with advanced multithreading and memory control capabilities. The object-oriented nature of this language allows developers to associate data with methods and process them together. This is similar to how blockchains use crypto chains to link blocks.

2. Simplicity

Simplicity is a programming language developed for blockchain. Increase productivity by hiding some useful components from developers. That’s why it’s getting a lot of attention in the developer community.

 This is one of the best programming languages ​​for creating smart contracts. There is a function to change the smart contract code after activation. This is one of the advantages of using Simplicity over Solidity. Simplicity has object-oriented features and uses the same principles as blockchain to prevent data changes. You can organize your program into a tree to reduce block space requirements and reduce transaction size.

3. JavaScript

Initially, developers found it difficult to use JavaScript for blockchain development. However, the creation of Node.js allows developers to use JavaScript to create innovative, high-quality blockchain applications.

The main advantage of using JavaScript is that you don’t have to worry about integration when using JavaScript for blockchain development. This allows developers to focus entirely on application logic.

 JavaScript is also becoming more popular in blockchain development because it can process code asynchronously. This feature is important for the blockchain as it can execute millions of transactions at the same time. JavaScript asynchrony allows programs to perform multiple actions at the same time, improving application performance and software responsiveness.

4. Python

Python is known for its simplicity. There is a large and active community releasing libraries such as NumPy, Pandas and SciPy. These libraries are used in a variety of engineering applications in science, mathematics, and engineering.

 Python excels at numbers, especially when it comes to data processing, cleaning, analysis, and visualization. It’s a great blockchain programming language because it can be used to create smart contracts, among other methods.

5. Solidity

Solidity was created for blockchain development and is considered one of the fastest blockchain programming languages. It is primarily used by Ethereum developers to create smart contracts. It’s similar to JavaScript and empowers users to build high quality decentralized applications.

Blockchain developers like to use Solidity for their Ethereum blockchain network. This allows developers to use Ethereum’s digital transaction books by creating smart contracts between enterprises.

To cstreamline the development process, Solidity uses preconditions, postconditions, and invariants. This also greatly simplifies the process of creating a user’s contract.

6. Java

Java is object-oriented, class-based, and parallel. It was loved by developers because it runs smoothly on all computers that have the Java Runtime Environment (JRE) installed.

In blockchain programming, Java helps you create interactive websites. You can use it to create a simple, immutable blockchain. Due to this immutability, the content or information in the block cannot be changed.

BlockChain Developer likes to use Java because of the high mobility. The program written in Java is not based on system-only systems and can be ported on almost all computing devices. Instead, run using a universal Java virtual machine.

7. Rholang

Rholang is a great programming language for developing smart contracts. The language takes a functional approach rather than an object-oriented approach. This is very helpful in solving many blockchain problems and is one of the reasons for its popularity. The Rholang application evaluates the entire program as a set of functions and resolves them in sequence. This is quite different from languages ​​such as C and Python, which use variables to store data and change their values ​​over time. As a result, Rholang has a functional programming model rather than an object-oriented model, making it the most popular blockchain development language in this category.

The above is a popular blockchain development language in today’s cryptocurrency and smart contract world. However, there is no clear advantage between them and it can be difficult to determine which is best for each situation. Each language has its advantages depending on the project you are working on. Therefore, you need to choose a language that suits your project’s needs, such as resources, budget, time, and features to add.
