9 Best Coding Languages to Learn for Cryptocurrency (Programming for Blockchain)

9 Best Coding Languages to Learn for Cryptocurrency

Do you ever wonder why Blockchain is suddenly gaining popularity and emergence? How does it work? 

Some of us must have wondered how cryptocurrency works. And can we make something out of it? Being an IT student, I thought about what this technology is and how it works.

I started to research and tried to find out how to make cryptocurrency and blockchain stuff and what is this. What is the future of this and how much am I going to make being a blockchain developer?

I studied and found the best Programming aka coding languages to learn for cryptocurrency and Blockchain.

There is so much to think about and ask. Let’s talk a little more about it. Bitcoin is a digital cryptocurrency built on blockchain technology. 

The world noticed that the price of a single cryptocurrency 1 unit went up to $65000, and what was the reason? Why did Elon Musk buy bitcoins? 

Have you wondered what’s going on and what’s happening on the internet? Yes, I bet you do.

The name of the technology suggests that it is literally a chain of blocks! In this context, “blocks” are digital information that is cryptographically linked together. 

Among the information contained in these blocks is a cryptographic hash function linked to the previous block. 

In addition, there is a timestamp and digital information contained in the block.

Due to the structure of these blocks, it is very difficult to modify the data, maintaining both transparency and security at the same time. 

Before diving into the scene, let us know a little bit about blockchain.

What is Blockchain?

There are nodes in a computer network that share a blockchain, which is a distributed ledger. 

Basically, a blockchain is a digital database that stores information electronically.

Bitcoin uses blockchains to keep a decentralized and secure record of transactions, which is why they’re so important. 

With a blockchain, you can get fidelity and security of your data without a trusted third party and you can build trust between yourself and your data.

Blockchains differ from conventional databases in their structure. Using a blockchain, a group of data is gathered together in sets of data called blocks.

A block of data is composed of several storage capacities that, when filled, are closed and linked to the previous block, resulting in a chain of data known as a blockchain.

Once a freshly added block has been completed, all the new information that follows it is compiled into a newly formed block, which will also be added to the chain once it has been completed.

Ok, enough said, I have come up with the Top 9 best coding languages to learn for cryptocurrency. Stay with me.

The Solidity programming language is an object-oriented, high-level language designed for the implementation of smart contracts.

An Ethereum smart contract is a program that governs the behavior of accounts within the Ethereum network.

Developed specifically for Ethereum Virtual Machine (EVM), Solidity is a curly-bracket language.

The language is influenced by C++, Python, and JavaScript. Solidity has been inspired by several different languages, which can be found in the section on language influences.

  • In the blockchain system, smart contracts implement business logic and generate a chain of transaction records.
  • You can use it to write machine-level code and compile it on Ethereum Virtual Machines (EVMs).
  • There are a lot of similarities between C and C++, and it’s pretty easy to understand. In Solidity, a “contract” is like a “main” in C.

Evolution of Solidity Programming

It’s a blockchain-based distributed computing platform and operating system made by Ethereum. 

  • In addition to Ethereum, Solidity is also the core language used by other private blockchain systems, such as Monax’s Hyperledger Burrow blockchain, which uses Tendermint and uses Tendermint for consensus. 


The JavaScript programming language lets you do more than just show static information on a web page — it lets you make complex features on the web page.

It lets you display content updates, interactive maps, animated graphics, scrolling video jukeboxes, etc. — it’s probably JavaScript.

The third layer of the layer cake of standard web technologies, two of which (HTML and CSS) we’ve covered in more detail elsewhere.

With JavaScript, you can create dynamically updating content, control multimedia, animate images, and pretty much anything else.

There’s so much you can do with JavaScript (okay, not everything.  

As the most popular web language, JavaScript is quite popular with Blockchain developers as well. Thanks to NodeJS, a JavaScript runtime environment, JavaScript is also quite popular with web developers.

JavaScript can be used to build highly-capable and creative Blockchain applications since it is already installed on most computers.

The fact that every web system uses JavaScript in some capacity is a major advantage JavaScript has over other programming languages.

JavaScript eliminates the need for developers to worry about integration and instead allows them to focus on developing the Blockchain application logic.

A good example is the Lisk Sidechain Development Kit (SDK), which enables developers to develop, publish, and distribute JavaScript-based Blockchain applications.

There’s a lot of competition between Java and C++. 

That’s true for Blockchain too! Java has an abundance of Application Programming Interfaces (APIs) including classes, packages, interfaces, etc. 

It’s great for building applications without having to know how they’re implemented. 

One of the things that make Java so useful in Blockchain is that it’s portable. WORA (write once, run anywhere) lets Java programs run on different platforms. 

Since they use the universal JVM (Java Virtual Machine), they don’t need any system-specific architecture. With Java’s portability and other popular features, it’s perfect for blockchain.

The PHP Blockchain language implements the blockchain data structure and proof-of-work. PHP programmers can use it as an introduction to blockchain technology.

There’s a record chain called a blockchain that’s immutable and orderly. You can put transactions, files, or anything else in them. They’re connected with hashes, but that’s what matters.


In recent years, Python has become the most popular programming language in the world and if you are a new developer with experience in Python, then this might be the most appropriate Blockchain language for you.

Python is an interpreted language, and this causes some problems for complex cryptographic operations in Blockchain applications.

  • Using JSON format, the data will be easy to implement and read. In each block, there are multiple pieces of data. Every minute, multiple blocks are added, so we’re planning to use fingerprinting to separate them.
  • We’ll use the SHA256 hashing algorithm to do the fingerprinting. To make sure it can’t be tampered with, every block contains its own hash and the previous function’s hash.
  • The fingerprints will be used to chain the blocks together. Blocks will be attached to each other by giving their hashes, and to the next block by giving theirs.
  • A new block is mined by answering the proof of work correctly. By making the proof of work difficult to exploit, mining must become more difficult. To make mining successful, the block will then be added to the chain.
  • In order to prevent any type of tampering with the blockchain, it is necessary to validate the validity of the chain after mining several blocks.
  • Following the development of the web application, it will be deployed locally or publicly as required by the user using Flask.


Any graduate knows how popular C++ is because many of us studied this in the starting semesters.

A major reason why C++ is so popular for blockchain applications is its many features, including move semantics, primitive memory control, multithreading, and other object-oriented features like function overloading, runtime polymorphism, etc.

As a result of these OOPS features of C++, blockchain developers can combine data and functions in one module easily.

This is similar to how Blockchain transforms blocks with cryptographic chains.

In fact, C++ is so popular with Blockchain that Bitcoin, a cryptocurrency, and the first-ever Blockchain implementation were written in C++.


Because Vyper is based on Python 3, its syntax is also valid Python 3 syntax, even though Vyper doesn’t have all of Python’s features.

The Vyper language was created as an alternative to Solidity. Just like Solidity, it’s used for the Ethereum Virtual Machine (EVM). Vyper, however, has a different control structure and handles security issues differently.

In addition to OOPS, Vyper has also removed features like infinite loops, modifiers, recursive calling, etc. By doing this, we’re able to avoid security issues.


Go is a great programming language for building fast and efficient Blockchain systems.

Go language (Golang)

Since Go is statically-typed and a compiled programming language, it is perfect for Blockchain coding. It also has other features that enhance performance such as generics, classes and inheritance, constructors, annotations, exceptions, etc.

It is the best language for creating hyper ledger fabric, which is a foundation for developing applications for Blockchain.

Go is also an uncomplicated language that can be learned easily. This is obvious by the fact that there are around 800,000+ developers on the Go language network.


The Rholang programming language is a great tool for developing smart contracts.

Rather than an object-oriented approach, this language uses a functional approach to solve many blockchain problems.

Its popularity can be attributed to this factor. A Rholang application evaluates the whole program as a series of functions and sequentially solves them.

This is a significant difference from languages like C or Python, which use variables to store data and change their values over time.

Hence, Rholang is the most popular Blockchain development language in this category and has a functional programming paradigm rather than an object-oriented paradigm.


As we discussed Blockchain is the future, so you should pick a path and start working on it. There are great opportunities and huge demand for blockchain developers all across the Globe.

Learn it and get to the place where you dreamed yourself to be. Good Luck.
