(Blockchain is an undistributed ledger used to record digital transactions.)

In recent years, we have come across the word blockchain many times. This buzzing term has gained significant attention in the recent decade.  Still, many of us do not understand what exactly blockchain is. Or how it works?

Blockchain is the technology that is responsible for the existence of Cryptocurrency. Blockchain is the foundation on which the whole crypto infrastructure is based. Bitcoin is one of the cryptocurrencies that used blockchain first. Since then, Blockchain has explored various forms of cryptocurrencies, decentralized finance, non-fungible tokens, and smart contracts.  The blockchain mechanism allows a transparent information exchange system within a business network. You should also know about Metaverse’s latest technology that can impact the market.

The idea behind the blockchain is simple, and it can potentially change the future from scratch.

So, let’s understand in detail what blockchain Is.

What is Blockchain?

In the simplest form, Blockchain is a distributed ledger that records and stores any kind of data. Moreover, it can record the information on the crypto transactions, NFT ownership, and Defi-smart contracts. The blockchain contains information in blocks linked together via cryptography.

These blocks link together using cryptographic information.

Blockchain is unique in its nature and totally decentralized, which means no other person could steal data from it. Blockchain data is not maintained in one place. Instead, many administrator copies of the blockchain are generated and distributed across different computer networks.

A blockchain is made of blocks linked together to form a chain known as the blockchain. It contains the growing orders of records, called blocks. Any information in the blockchain could not be recorded retroactively without the changing of subsequent blocks. Blockchain can be used anywhere in any industry to make data immutable.

How does blockchain Technology work?

We all are familiar with traditional spreadsheets, Excel books, and databases. These are traditional ways to store information in a systematic manner. A blockchain is somewhat similar to these methods, but it’s different in the way it structures and accesses the information. This decentralized digital ledger is made of individual blocks of data.

When the data in the block is accessed or altered, the entire information is encrypted via unique and unchangeable technique hashes created via the SHA-256 algorithm. The new information added in the blocks does not create any problems, and blocks are appended together so that any change can be monitored easily. Since the highly secured technology encrypts blockchain, records are immutable, and any change in the ledger can recognized by the network and rejected.

The information secured in the block is permanently chained together, and transactions are recorded identically and sequentially, forming a perfect audit history pattern that allows into the past version of the blockchain. Whenever new data is added to the blocks, most nodes verify the information and legitimacy of the data through its consensus algorithms. Cryptographic transactions must ensure that the transaction in a new block is safe or that the coins are not spent more than once.

Key components of the Blockchain:– 


Decentralization is one of the prime features of blockchain technology. In the conventional method, you require permission from central authority governments for transactions. On the other hand, blockchain facilitates smoother and faster transactions with the mutual consensus of users without any interruption.


Blockchain is secured based on one of the most robust technologies, cryptography, and no one can steal information from it. Eventually, if a transaction includes an error, new information must be added to correct the information, and then both transactions will be visible.

Smart contracts:- 

Smart contracts are automatic protocols fed into the blockchain and executed automatically when their predetermined conditions are met.  Moreover, it simplifies the process by atomically confirming all conditions, removing the parties’ need to trust each other.

Why is blockchain important?

Businesses run on information. And the accurate distribution of this information is important to success in a business. The faster they receive and deliver the information, the better. Furthermore, Blockchain is suitable for businesses bringing a system that facilitates immediate, shared, and completely transparent transactions secured on the digital ledger.

Blockchain technology offers security in many ways; for example, new information is added to the blocks after verification. After adding a new block to the chain, the previous block can not be altered.  If any change occurs in one block, the whole will change the whole blocks.

Types of Blockchain:-

There are different types of the blockchain. They include:-

Private Blockchain:-

Private blockchain works on closed operations and is specially designed for private and individual operations. Moreover, Companies use these types of blockchains to customize their authorization and accessibility preferences and other security parameters.

Public blockchain:-

Public blockchain plays an important role in the popularization of distributed ledger technology. These blockchains also help to eliminate major changes and security concerns. Public blockchains are permissionless, so anyone can join them. They provide equal rights to everyone to edit, read, and validate the blockchain.

Permissioned Blockchain Networks

As the name suggests, permission blockchain was only designed for the specialized access of authorized persons. These types of blockchains are specifically used by organizations to connect with both worlds.  They set better structures when it comes to assigning who can participate in the network and what transactions need to be placed.

Consortium Blockchains

Like permissioned blockchains,  consortium blockchains have public and private components, except multiple organizations will manage a single consortium blockchain network. Although these types of blockchains can initially be more complex to set up, once they are running, they can offer better security. Additionally, consortium blockchains are optimal for collaboration with multiple organizations.

Hybrid Blockchains

Hybrid blockchains are the fusion of both private and public Blockchains. In this type of blockchain, some parts are public, while authorized and specific participants access others. Hence, this type of blockchain is suitable in organizations where balance is required to maintain transparency and privacy.


Sidechains are a type of blockchain that runs parallel to prime Blockchain, offering better functionality and scalability. Developers can experiment with new features and applications with these blockchains without affecting integrity. Side chains can be used to create decentralized applications and employ specific mechanisms.

Blockchain Layers

Blockchain layers refer to a typical concept of building multiple layers of the blockchain on the top of each layer. Each layer of the Blockchain has its own functionality, which makes it unique. This method ensures scalability, as transactions can be processed very smoothly across different layers.


In this article, we have understood the widespread importance of blockchain in cryptocurrency and defi system. Therefore, getting ahead is always essential to make your business successful. Blockchain is helping businesses to transform at a greater pace with distributed ledger technology and permissionless transactions.


1. What is Blockchain, in simple words?

Blockchain is a decentralized database that records cryptographic and other types of transaction details. Furthermore, the Information recorded in the blockchain is difficult to modify or change.

Blockchain is a shareable ledger that records transactions and is difficult to modify or change. It also tracks tangible and intangible assets such as cash or a house.

2. What are the main types of Blockchain?

There are several blockchain platforms available there. The most common Blockchain types include public blockchains, private blockchains, consortium blockchains, and hybrid blockchains.

3. How are public and Private Blockchains different?

Private blockchains are only limited to individual uses. In contrast, anyone can access the public blockchain.

4. What is a Blockchain Platform?

A Blockchain Platform is any platform that exists to support or facilitate Blockchains. Moreover, many types of blockchain platforms exist for different needs, such as Ethereum, Hyperledger, etc.

5. Who Invented Blockchain?

Blockchain was created by the pseudonym Satoshi Nakamoto, who created the world’s first cryptocurrency, bitcoin.
