Blockchain technology is gaining popularity as it comes with increased security, it is a lot more transparent, and the exchange of information is fast. Given all the advantages, small and big enterprises, including the banking sectors, are interested in using the services. With the popularity of Bitcoin and cryptocurrency, a lot of developers are interested in creating blockchain-related software and tools.

Blockchain programming is not straightforward. It involves thousands of mathematical, scientific, and arithmetic algorithms. These algorithms are used for processing different engineering functions. There are many languages with which you can develop blockchain-related projects. However, of all the options available, Python holds an edge. Python comes with many powerful function libraries, third-party functions, and built-in modules. All these features make it the most preferred language of blockchain technology.


Basics of Blockchain

Before we discuss more about Python, let us first try to understand Blockchain a bit. Blockchain stands for a distributed database. It facilitates a transaction between two parties without any requirement of any intermediate body. For example, to transfer money to your friend, you need a bank that will deduct money from your account and deposit it to your friend’s account. In the blockchain, there is no such requirement (no bank required).

Blockchain is written in C++, but data scientists and python development companies that build blockchain applications prefer to use other trending languages. Blockchain finds use in architecture programming and for developing smart contracts or decentralized apps.

Of all the languages that can be used to build blockchain applications, we will focus on Python language. Python language is an interpreted high-level language designed for general purpose programming. Its design philosophy places high emphasis on code readability with its use of significant indentation. Through its language constructs and object-oriented approach, it helps programmers write clear, logical code for small and large-scale projects.

Below are the top five reasons why Python is used for blockchain projects:

1.It is advanced and also easy to learn

Python is not a new language. It has been around for a while now. However, unlike other programming languages that fade with time, Python has become stronger among the developers’ community. It has evolved as a language over the years, and at present, it is at an advanced stage. Python gives developers the feeling of reliability and stability.

Blockchain projects are for the future. Before you pick the language for Blockchain application, you need to be 100% sure – it does not become obsolete. The way Python is growing in popularity, the chances of it becoming obsolete is close to 0.


It is easier to learn for the developers, even for the ones with less development experience. Developers can start coding on Blockchain projects just after weeks of training in Python.


2. Python is simple to use

Simplicity is the core philosophy of Python language. The features the language provides, speak volumes of its simplicity level. For example, white spaces in Python signify code blocks. If you have coded code blocks, you don’t have to worry about adding any keywords or curly brackets.


A language is simple if it can do more with fewer lines of code. Python does exactly that for you. You can code blockchain without having to write a lot of code. Can you guess how many lines of code you need to write to make a simple blockchain? It is less than 50 lines.


Python is preferred for Blockchain because developers can easily perform multiple tasks with a single command. You can work on building blocks with relevant information and link them together without much effort.


3. It is trending and is a future language 

Another reason why you should consider Python for your blockchain projects is because of its popularity. Pick up any list of trending programming languages, and you will find Python among the top three languages on all the lists.


If you build a big blockchain project, you would obviously need more people in your development team. Given the popularity of Python, you can easily find python developers who have significant hands-on Python.


The fact that Python is quite popular brings more to the table. If you are stuck somewhere in your blockchain project, you can find the solution to problems from the community members. Most members are more than happy to share their knowledge. They have also built libraries that can be used by others.


Earlier, we mentioned that Python is here to stay. One of the reasons for it is that there are a lot of resources available on Python like PDFs, guides, and video tutorials. Using this, a lot of students are learning Python for free and you will see more Python developers in the future. At the same time, there are many blockchain enthusiasts, and it creates a perfect combination.


4. Free packages for Blockchain

If the above points have not convinced you that Python is the best language of Blockchain, this point should. Developers get a collection of free packages that helps them write code more efficiently when they use Python for blockchain projects. It also consists of cloud-media services that provide cross-platform support via a library such as a tool.


5. Option to Run compiled and uncompiled

Python is a scripted language, and hence it does not need compilation to be understandable to machines. Let us understand this advantage with an example. Let us suppose you are working on a blockchain project and came across an error. If you are using a compiled language, in order to resolve the error, you will first have to stop your project, go to the source code, make changes to the code to fix the error, and then restart your blockchain project.


In Python, it is a single-step process. All you need to do is fix the error and reload the app. There is no re-compile required or stopping of application. However, making changes to the code directly can lead to adverse effects on the speed of the scripting language. To overcome this problem and enhance the performance, Python provides a feature of re-compiling utilizing different methods.


Blockchain projects have very specific requirements when it comes to language and code. When selecting a programming language, you have to ensure the language is scalable and secure. Python provides you with both these features. As you must be knowing, anyone can add a new block to your blockchain, hence your code should be capable to deal with a growing query list. Python covers developers from even this perspective.

Python gives everything to developers that they need for blockchain projects, and developers may not find any other language that will make the development of blockchain projects so comfortable for them.
