What is Blockchain?
Blockchain in its most literal and basic sense is a chain or string of blocks linked together. It is a distributed, P2P (peer-to-peer) network.
One of the most important characteristics of Blockchain that distinguishes it from other database systems is its decentralized nature. This implies that the control or authority is not in the hands of a sole owner or a single organization, but is distributed to all the nodes participating in the network.
Blockchain transactions support transparency. A copy of every transaction is accessible to all users on the network and they can easily track if any alterations are being performed. Due to this feature, it is nearly impossible for someone to tamper with the data or the information present in the blocks, thereby mitigating the risk of fraud. This makes Blockchain highly reliable and secure.
Now that we are familiar with the term, “Blockchain”, let’s have a quick glance at some of its characteristics.
Why is Blockchain so popular?
Blockchain is extremely popular in the IT industry today and it owes its success to some of its unique and amazing characteristics. Here are some of the features of Blockchain Technology that differentiate it from other database systems:
- Blockchain is immutable, i.e., it is permanent and the data on it cannot be altered.
- It follows the peer-to-peer network architecture.
- It supports the transparency of transactions while maintaining the privacy of data.
- Blockchain is decentralized.
- It is more secure.
- In order to make fair and quick decisions, Blockchain follows a consensus mechanism.
We have now understood what Blockchain means and why it is so popular. It is finally time that we get around the main topic of the blog: Blockchain Programming Languages.

- Kubo: It is the oldest version of the IPFS implementation. It is basically used as a library in GO development.
Ethereum Go: By using Ethereum Go, developers can build dApps and the Ethereum network using Geth and employ Ethereum Go to launch and manage Ethereum nodes.
1.5. C++
Other than Python and JavaScript, C++ is the most popular programming language in the tech world today. Moreover, its amazing features such as move semantics, multithreading, and object-oriented programming, make it one of the most popular languages in the case of Blockchain as well.
- Compared to any other programming language, most Blockchain projects are built using C++.
- Moreover, the first currency of Blockchain technology, i.e., Bitcoin, was originally written in C++ language.
- When we talk about Blockchain programming, EOS or Electro-Optical System utilizes C++ most frequently, due to its flexible features.
- It supports compile time polymorphism and exhibits efficient CPU management.
- It is a high-speed, multiplatform programming language that is ideal for Blockchain programming.
Other than these, Blockchain programming languages for front-end and back-end development are Rust and Golang. These are considered to be advanced language options.
2. Contract Languages
These are the languages that are used to build decentralized contracts or smart contracts. It usually depends on which chain you want to deploy and then consequently which language you’ll use.
Most of the popular chains today are EVM (or Ethereum Virtual Machine) compatible. Some of the most important languages that are used for building smart contracts are given below:
2.1. Solidity
It is a new and rapidly growing programming language created primarily for building Ethereum-based smart contracts. If a developer solely wants to focus on Blockchain programming, learning Solidity is the way to go.
