Blockchain, Top 4 programming languages

Living is impossible without applications. Our life is replete with social media apps like Instagram, Telegram, and such programs. Many of these programs have a centralized structure. In other words, in such structures, data is controlled and kept in their servers. The single point of failure is another issue with this type of structure. That is to say, in case of problems in the center, the whole network is in trouble, which can lead to the server being inaccessible. Are there any solutions to these issues? Certainly, Blockchain language is our technical assistant when these issues occur. Moreover, since it is secure, it prevents scam.

Before we start the topic, it is worth studying the recent blog post we have published, “Programming languages ranking“.

What is blockchain language?

Blockchain language was introduced in 2008. David Chaum brought up this primary concept in 1982, and the 2008 outcome is the latest update.

Blockchain language is a combination of the words, block and chain. To clarify, this advanced technology is a chain of blocks. Each block retains information, and they relate in a sequence. The structure is complex enough to protect against any vulnerability. Consequently, the model has maximum security.

Blockchain is not a single technology itself. It is comprised of complicated processes, like hashing, cryptography, collective distribution, etc.

Some types of blockchain

There are four different type of blockchain technology.

  1. Public blockchain
  2. Private blockchain
  3. Hybrid blockchain
  4. Sidechains

Some similarities in between them

All blockchains have a cluster of active nodes on a peer-to-peer (P2P) network system. Each network node has a copy of the distributed general ledger which is updated instantly. Each node can approve, start and receive transactions. In addition to creating blocks. Let us explore each blockchain a bit deeper.

Public blockchain:

The first type is a public blockchain. This open-source chain does not have any restrictions on data access. People can access it via the internet as a developer, miner, community members, or users. Bitcoin and Litecoin blockchain are popular public blockchains, because the main function of a public blockchain is for mining and exchanging cryptocurrencies.


  • Reliability
  • High security
  • Transparency


  • Low TPS
  • Scalability issues
  • Energy consuming

Private blockchain:

The name helps us understand the phrase. A private blockchain is mainly deployed in a company or organization. The main consideration here is the number of users. The people involved are permitted to join by the administrator. Private blockchains and public blockchains are used in the same vein. However, private blockchains are more restrictive and centralized. Multichain and Corda networks are examples of private blockchains that are growing as time passes.


  • Faster than public blockchains
  • More scalable
  • Adaptive support


  • Less secure
  • centralization
  • Need to build trust

Hybrid blockchain

The dictionary defines hybrid as”something that consists of or comes from a mixture of two or more other things”. In other words, it is the pros of public and private blockchains put together. Not only does it advantage from the privacy of private blockchains but also the security and transparency of the public blockchains. So, the third type is a win-win situation. Dragon Chain is an example of a hybrid blockchain.


Sidechains are a separate part of the blockchain that is connected by a two-way connection. This mechanism assists blockchain ledger, so the blockchain becomes more scalable and efficient.

What is a programming language?

A language is a system of communication. Throughout human history, we have searched for ways to communicate with others. However,in the era of technology, the story is a bit different. In addition to humans, we need to talk to computers. The question here is, can we talk to computers in the same way we talk to people? The answer is a resounding NO. That’s where programming languages come into play.

A programming language is a computer specific language. In fact, computers work with voltage. We think of it in terms of 1 and 0 (binary). Binary language (machine language) is hard to code, so programmers decided to invent more programming languages. Nowadays, programmers can look for many languages and choose the best fit for their project. Programming languages include :

  • Solidity
  • Python  and its widely used framework React js
  • Simplicity
  • C++
  • Java

  • C++

C++ is a programming language that was first introduced by Danish mathematics in the 1970s. It is a part of the C# language family. This language profits from low-level and high-level languages.


  • Faster than most programming languages
  • Hardware and software compliance
  • Strong libraries like Tensor Flow
  • Runs perfectly on all operating systems (Windows, Mac, Linux)

Many blockchain language projects are carried out in C++. That is why it is the fourth popular language. C++ has a lot of potential benefits. Above all, this language aids in very effective memory management. Applications programmed with C++ are very fast in conducting transactions. Therefore, projects such as Bitcoin are in C++.

  • Java

Java got started in 1991 intending to create a new portable language. ” Write once, run anywhere” is the motto of Java. After compiling programs convert in Bytecode format. So, the programs run on the platforms without any manipulation.


  • Simplicity
  • Object-oriented
  • Dynamic
  • Secure
  • Portable

Users deploy Java to build a simple and immutable blockchain. Consequently, the possibility of changing block information or adding a new block is low. Hence, it is a good option for private blockchains.

  • Simplicity 

Simplicity is the third language. It was introduced by Russell O’Connor in 2017.

According to the language instructor, Simplicity is extremely simple to use. It’s a typed, combinator-based, functional language without loops and recursion. Each well-typed expression joins with an input type and output type. This low-level execution language is an alternative to Bitcoin Scripts. Moreover, smart contracts fully accomplish with Simplicity. It improves the basic languages of digital currencies such as Bitcoin and Atrium.


  • It does not have any function types
  • No named variables
  • No loops or recursion
  • A low-level language
  • Solidity

Solidity, an object-oriented language, was designed in 2014 by a group of developers. It has a close relationship with C++, JavaScript, and python.


  • Static data type (you need to define a variable and its type before using it)
  • Contracts and interfaces 
  • Function modifier (Like rewriting functions in an object-oriented programming language)
  • Events (An event is similar to a function that receives data as an input. Then, puts it on a blockchain log)
  • Determining the level of accessibility
  •  Different libraries

This brand-new language is used to create smart contracts in the Ethereum blockchain. Solidity defines smart contracts (explained below):

A contract is comprised of data and a string of codes with an address in the Atrium network.

To sum up

In this rich article, we covered the top four types of blockchain languages. C++, Java, simplicity, and solidity are the most popular blockchain language programming tools. We are certain that the choice of the language is so important. Because process of creating design is based on your software development needs.
