Top 5 Programming Languages Used in Blockchain

If you are a tech-lover or a programmer you may have heard the name of Blockchain. It has already been confirmed that Blockchain technology has changed the world. Do you know what programming languages are behind the Blockchain? In the whole section, we will guide you to the top 5 programming languages used in Blockchain.

AtoZ Markets If you’re a tech-oriented person, you may have wondered at least once about all those latest news regarding blockchain and cryptocurrencies

Therefore, what is blockchain technology and why you want to learn more about it? 

Blockchain is basically a chain of blocks. It is connected sequentially with complex cryptographic logic. A person, named Satoshi Nakamoto first introduces this technology to the world and the first user of this technology is Bitcoin cryptocurrency. 

Moreover, there are many industries that use blockchain technology to ensure the high-level of security for their business transactions. From companies to retailers, blockchain technology works equally. 

Therefore, you can wield a modern-day skill by learning the best blockchain programming language used in blockchains. This will guarantee you to have an edge over your fellow developers.

What is a Programming Language?

Programming languages are essential to ensure that blockchain networks and crypto infrastructure are safe and secure.

Their role of the programming language is simple. It enables a computer to understand the Blockchain instructions. However, there is some overlap in the programming languages to develop traditional software and technologies. Therefore, in blockchain platforms, the workflows and skills may require to create successful projects.

Maintaining a public blockchain using the programming language is not an easy task. The language code should be absolutely bulletproof to ensure that hackers cannot attack it. Therefore, language creations may slow down the process substantially as developers need extra effort on every loophole.

Programming languages are instrumental to ensure that the blockchain network can run smoothly in terms of transaction processing. To achieve this automation, programmers often use smart contracts. When predetermined conditions are met, the programming code enables these agreements between parties. The benefit of using the language is that it eliminates middlemen. Therefore, it does not need to eradicate lawyers or notaries. Anyways, it can take intensive levels of coding to ensure the right.

Besides these, some blockchain includes the development of decentralized applications (DApps) as well as the execution of crowdfunding initiatives.

Top 5 Programming languages for Blockchain

If you are looking to be a programmer for Blockchain or you are enthusiastic about the blockchain technology this section will allow you to see the top 5 Programming languages that are used in Blockchain. Stay with us throughout the guide to have in-depth insight into this list of modern-day blockchain coding languages. 

There are many coding languages for Blockchain developers. Among them, we will discuss the top 5. The selection of the top 5 is based on our research. We emphasize the simplicity and objectivity of programming languages to select the top 5.

Programming Languages Used in Blockchain

First, let's list the 5 Programming languages for Blockchain before moving one by one.

  • C++
  • Java
  • Solidity
  • Simplicity
  • Python

Our aim is to equip you with the necessary knowledge of the best programming languages for blockchain technology.


This is one of the most popular programming languages in the tech world. Moreover, it is also a dominant force in the blockchain industry. For Blockchain technology, object-oriented language is perfect. Therefore, the encapsulation, abstraction, polymorphism, and data hiding, are good for blockchain to prevent edits to data.

Another feature of C++ is memory control capabilities. The language helps to ensure the security of blocks. Moreover, it allows a large number of resources on each network node to accept or reject the particular block.

Blockchain development services also use C++ to handle parallel tasks and threading. The C++ language is capable of handling both parallel and non-parallel tasks besides improving the single-thread performance.

EOS is a perfect example of a blockchain program built with C++. The open-source software was released by Block in 2018. This program is made to increase transaction speeds than alternatives by limiting the software to produce nodes. Moreover, the software confirms the transaction in less than a second to finalize it in just two minutes.


Java is the only language that can challenge the reign of C++. In the Blockchain industry, Java is in many ways similar to C++ for its object-oriented approach. Moreover, it has a vast community of third-party platforms and applications. Another reason to use Java is its portability. Java uses the de-facto blockchain programming language in the industry that is highly portable.

Java programming language is portable in any computational device. Therefore, Java does not rely on system-specific architecture. Instead, they use universal JVM for execution. This makes Java one of the best programming languages for blockchain.

Solidity is a blockchain and smart contract development language. Most Ethereum developers use this. This is basically a domain-specific language that uses similar principles and syntax of JavaScript. Therefore, it is able to create high-quality decentralized applications.

Developers prefer this language as it allows them to write high-level code for the Ethereum blockchain network. Moreover, this language can come into low-level machine code. Moreover, it allows individuals to utilize the Ethereum digital transaction ledger. So the language can create smart contracts between businesses.

As a contact-oriented language, it uses invariants, preconditions, and post-conditions to streamline the development process.  Moreover, this language can make the contract generation process simpler for users.

However, the solidity is available on several blockchain platforms, including Ethereum, Ethereum Classic, Tendermint, and Counterparty. 


Simplicity is a new programming language compared to Java and C++. This programming language was released in November 2017 and designed specifically for smart contracts and blockchain networks. This language hides low-level logical components to increase productivity and avoid the distractions of developers. Therefore, it is rapidly becoming popular among the community.

Like C++, Simplicity is also an object-oriented language. It uses the same principles of blockchain to prevent errors and changes to any data. Moreover, it uses Merklized Abstract Syntax Trees. Therefore, it can organize programs into trees. By doing so, it allows transactions in smaller sizes and reduces block space requirements.

The Simplicity creators, Blockstream, are still working to expand the language and its capabilities. Most of the developers can expect to see Simplicity as a most used application within the mid-2020. Moreover, the language is included in Bitcoin with finalizing features.

If you’re a new programmer and looking to get your hands dirty in this fantastic world of blockchain development, Python is the right choice. This programming language may turn out to be the best blockchain programming language for developers.

Programming Languages Used in Blockchain

Python tends to underperform during complex cryptographic operations due to its nature. However, Python allows developers to prototype their ideas sooner. Moreover, Python can write programs in an object-oriented approach. Therefore, users can utilize it to cope with many of its performance overheads.


As we know, Blockchain is in the world to stay. The popular record-keeping technology makes cryptocurrency exchanges possible. Moreover,  Governments of many countries, Corporations, individuals, and others for software development use this technology.

Among the above-mentioned languages, C++ and Java are very suitable for blockchain development. Alternatively, blockchain-specific languages like Solidity and Simplicity can make cryptocurrency development easy and smooth.

However, we may see some more programming languages in the next several years, as the blockchain market ever-growing and uses of cryptocurrency are increasing day by day.
