5 Reasons why Python Is Good for Blockchain

Python makes an excellent language for Blockchain projects because it is secure, performant, and scalable. It is also advanced and reliable, and safe.

Finally, Python has free packages for Blockchain. Even though Blockchain is written in C++, many developers and data scientists turn to other languages for building their blockchains. Learning Python will definitely give you an advantage over other developers to work in the industry. Here are five good reasons why Python makes an excellent language for a Blockchain

1. It's advanced and easy to learn

Python has been around for a while now, and its position on the tech scene is growing stronger. Since it's supported by a large and passionate community of developers, Python has significantly evolved as a language and is now at an advanced stage, which guarantees stability and reliability.

It's a technology with a bright future, so you can rest assured that your project won't be based on a language that is on its way to becoming obsolete.

Moreover, Python has a gentle learning curve, making it easier for developers to master it within a reasonable time-frame, and even allows for less experienced developers to contribute to Blockchain projects immediately.

2. Python is simple and minimalistic

Simplicity and minimalism are at the core of Python's philosophy. Its simplicity derives from many different features – for example, in Python, white spaces signify code blocks, and developers don't need to worry about adding curly brackets or keywords. They can use Python to code a blockchain without having to write a lot of code. To illustrate, Python allows to create a simple blockchain in less than 50 lines of code.

Moroever, Python is recommended for blockchain because you can easily perform many tasks with a single command. It makes the work of building blocks with the relevant information and linking them together a much easier one to do.

3. Python is popular right now

Another feature that makes Python an excellent choice for a Blockchain-based project is its popularity. Have a look at this year's TIOBE index, and you'll see Python occupying the third place among all programming languages. And the index shows that its popularity is continually growing.

In practice, this means you'll have an easy time building your project team because there are plenty of developers out there who specialize in Python, including professionals with an academic or scientific background.
But easy access to Python experts isn't everything. The language’s popularity also means that your team will take advantage of Python's vibrant community, which shares knowledge and builds useful libraries.

4. It can be run compiled or uncompiled

Contrary to C++, Python is a scripted language that doesn't require compilation to become understandable to machines, which makes developers’ lives more comfortable.

Imagine running an application and noticing a bug. If you're using a compiled language, to fix it, you'll have to stop the application, return to the source code, fix the bug, recompile the code, and restart your application.
In Python, all it takes is fixing the bug and reloading your application – you won't have to recompile code. And that's a massive advantage in building blockchains.

Translating code on the fly can negatively affect the performance of scripting languages. That's why Python offers the option of pre-compiling the code along with many other techniques that speed it up, giving developers working in Blockchain a choice.

5. It has free packages for Blockchain

Another significant advantage of using Python in a Blockchain project is that it offers developers a collection of free packages to help them write code more efficiently.

Choosing a programming language for Blockchain

Blockchain has specific requirements when it comes to code and language. In general, when choosing a programming language for a Blockchain project, make sure that the language is secure, performant, and scalable. You need an advanced and reliable language to make your blockchains as safe as possible – and Python can help you with that. Since anyone can add to your blockchain, your network and code should be able to deal with a growing query list. Python has that covered as well.
Finally, a Blockchain application needs to allow anyone to add to the chain without these transactions being processed in parallel. You need a speedy and versatile language for that – and that's why you should choose Python.
