Everything you need to know about Blockchain Programming


Blockchain has always got a lot of attention of the tech fanatics all over the globe. The blockchain has great potential to replace and disrupt the traditional systems for transacting assets and data.  So, let’s dive into this blog and look at different aspects in terms of Blockchain Programming.

What is Blockchain?

The Blockchain is a decentralized digital public ledger for the transactions. It is not checked or verified by the government, but it is secure to use as a distributed network of verification of miners using high-performance machines are set up. The blockchain technology is expected to replace the modern business processes effectively with the passage of time.

There are multiple things you must know about the blockchain programming in order to build apps and start working flawlessly on the platform. To get started with, you must know about the types of blockchain programming along with the platform it works on and the language by which you can communicate to the systems.

What are the types of Blockchain programming?

Building a decentralized app or a smart contact (DApp)

In a regular centralized application, the backend code is based on the centralized servers, but it is not the same with Dapp. The backend code of Dapp works on the decentralized peer-to-peer network. Just like the regular app, Dapp has its frontend code in any understandable language and a usual user interface which is meant to make calls to the backend.

Blockchain Architecture Programming

Before releasing the blockchain, the important features which consist of the protocols and architecture must be resolved. The protocols and architecture should be written in the code format. The general coding of the following format uses languages like Java and C that works closer to the machines. For instance, before the launching of the bitcoin blockchain in 2009, the rules which governed the situation were written in C++.

Which are the most reliable Blockchain programming platforms?


Ethereum is considered to be the most popular and widely used platform for blockchain programming. It is an open-sourced platform for blockchain for the development of decentralized apps or Dapp(s). It facilitates smart contacts or scripting run through the nodes of the network. Ethereum not only tracks the transactions, but it also programs them. The smart contacts in ethereum are built using the contact oriented, solidity, high-end programming language.


Hyperledger is a unique umbrella project for the open source blockchains hosted by Linux Foundation. It provides the required training, events, and tools for the development of the blockchain based digital ledgers. The Hyperledger mainly aims to supply the modular blockchain technology which shall be based on efficient and user-friendly application programming interface (API).

Hyperledger tries to minimize the security risks and makes sure that the parties which are trying to make a transaction are the only part of the transaction process. It offers user-friendly capabilities in terms of blockchain architecture, immutability, the privacy of data, and the sharing of information.

Which languages are used for the blockchain programming?


C++ is the oldest yet the most favored language among the blockchain programming developers. C++ reduces the coding time with the creation of the packages of objects, data, and functions as they can be used and called in any other programs. C++ can flawlessly handle the challenges related to the blockchain programming by its efficient resource management.

C++ gives a fluidic control over the CPU of the user by maximizing the usage of the processing power of the machine. The blockchains have to deal with the various unsecured and untrusted nodes for the communication, so C++ provides an adequate amount of security to the users as well.

C++ is a high-speed platform with the handling of both non-parallel and parallel tasks. It allows the multithreading with the optimization of the single thread performance. It is widely used in the extensive blockchain projects and cryptocurrencies like Ripple, Bitcoin, Litecoin, and Bitcoin cash.


Python is one of the top languages for software development and blockchain programming. Python works on various platforms, for instance, Mac, Windows, Linux, Raspberry and more. It is used to connect the various database systems with the ability to handle large data operations and complex maths. The syntax of the language allows the users to write their programs with less number of lines in comparison to other programming languages. The prototyping is very rapid on the language as it runs on the interpreter system offering a swift approach. Unlike other programming languages which use semicolon or brackets to complete the command, python uses new lines which are easier to implement.

Python is a popular modern language among modern coders. Nearly one or more public tools in the blockchain ecosystem are written in Python.


Java is one of the most renowned languages in the field of software development. Javascript is widely used to make interactive web pages. Javascript and its framework and libraries are the drivers of the development of the modern web. Few instances of the framework and libraries include Node, Angular, jQuery, and React.

The Javascript is very synchronous and efficient when it comes to handling the blockchain operations. It is very object-oriented and prototype-based language which even supports functional programming. Javascript can even work efficiently with the simultaneous increase in the number of users of blockchain and can handle the corresponding communication between various blockchain nodes. However, javascript fails at using the maximum power of processing power of the computer like C++.


Solidity is the domain-specific, high-level, object-oriented language resembling javascript. It is mainly designed for the creation of the decentralized applications or Dapps on the Ethereum platform. The language is statistically typed and even supports libraries, complex user-defined types, and inheritance. It is commonly used to develop the Ethereum smart contacts. Solidity is easy to learn and implement language whereas it has limited usage.


GO is a modern domain language developed by Google. Go is statistically typed with similar syntax as C language. It is the mixture of the positive aspects of various languages such as user-friendliness of Javascript and Python with the security and performance of C.

Go allows the flexibility to the users which provide ease in blockchain programming. The compilation timing of the language is comparatively fast, and it also provides the ability of the garbage collection as well.


Blockchain technology is targeted to bring evolution in every industry and sector. It is gradually changing the traditional methods of decentralized transactions. The blockchain programming can be hectic at the first go, but it will be easier when you master the favored language of your choice.
