Updated on 20th Sep, 23 7.5 K Views

Everything has changed with the advent of blockchain. Blockchain technology has played a major role in altering the world by eliminating the flaws of centralized systems. It has facilitated decentralization. Any organization can boost its processes to new heights by utilizing blockchain.

I think we have made you curious about getting into the roots of Blockchain. But before discussing what is blockchain and what are the types of blockchain, let’s have a quick look at the topics we are about to cover in this article.

Blockchain Overview

Blockchain was created in 2008 by Satoshi Nakamoto to operate as the public transaction log for the cryptocurrency bitcoin. As a consequence, bitcoin emerged as the first digital money to solve a double issue without the assistance of a central database or trustworthy agency.

Blockchain is a technique of preserving information that makes it difficult to update, hack, or manipulate the system. A blockchain is a distributed ledger that copies and distributes transactions throughout the blockchain’s network of computers.

What is Blockchain?

Blockchain technology is a framework that maintains public transactional records, also referred to as blocks, in many databases connected by peer-to-peer nodes. This type of storage is sometimes referred to as a “digital ledger.”

Every transaction in this ledger is authenticated and protected from fraud by the owner’s digital signature. As a consequence, the data in the digital ledger is completely safe.

Types of Blockchain

Now that we have acknowledged blockchain technology, we must explore the several types of blockchains, which are classified based on blockchain applications.

  • Public Blockchain
  • Private Blockchain
  • Hybrid Blockchain
  • Consortium Blockchain

Public Blockchain

Blockchains that are accessible to the entire public are called public blockchains. In these blockchains, there are no limitations on the user and validator roles. This type of blockchain serves the main advantage of its uncontrollability, which denotes that nobody will be able to completely control the network.

As a consequence, it safeguards the data’s security and supports the information’s immutability. A completely distributed public blockchain will arise from the equal power of all nodes connecting to it.

Private Blockchain

As the name suggests, people must be asked to join this blockchain in order to participate. Only those with access to the blockchain ecosystem may view any transactions. Compared to public blockchains, these blockchains are much more centralized and controlled.

These blockchains may be governed and supervised by an individual who can guarantee that the administrators are guiding participants since they are more centralized. Depending on the blockchain owner’s choices, these chains may or may not include a token.

Private blockchains frequently have a network administrator who controls user permissions in the case that one user suddenly requests additional power. They are frequently employed in private businesses to safeguard sensitive data about the organization.

Hybrid Blockchain

There are two categories inside this blockchain, with some sites being confidential and others being accessible. Some nodes will therefore be allowed to take part in transactions. The decentralized network will be run by the other nodes. A mix of public and private blockchains makes up this blockchain.

In this scenario, any node can access the blockchain, but the quantity of data that can be accessed depends on which node is accessing that particular data. Typically, there are two sorts of users on this blockchain. The blockchain is completely under the authority of one individual, who also decides how much security each user is afforded, while everyone else can only access it.

Consortium Blockchain

A consortium blockchain is a type of blockchain network that is collectively controlled and operated by a group of organizations rather than a single entity. It is designed to bridge the gap between the fully public (permissionless) blockchains, like Bitcoin and Ethereum, and private (permissioned) blockchains.

Example of Blockchain

Blockchain technology enables the construction of a decentralized public digital information record. The data (the block) is kept in a publicly accessible database (the chain) and can contain any type of information. It is the first digital technology that allows insecure parties to refer to a single, permanent (append-only) digital record. Blockchain already has several uses, some of which are listed below:

Bitcoin

Bitcoin is a well-known example of a Blockchain in operation. It is a type of digital money commonly called cryptocurrency. This totally electronic form of funds can be transmitted safely from user to user without the need for middlemen which, basically means there is no requirement for a central bank or administration. Bitcoin is not the only cryptocurrency that uses Blockchain technology. Bitcoin Atom (BCA) is a Bitcoin fork that offers a genuinely decentralized method of exchanging cryptocurrencies with no trading fees and no exchange hacks.

Spotify

Spotify ties artists with licensing agreements and tracks utilizing a decentralized network (blockchain technology). The use of Blockchain in music aims to produce a more transparent record of rights ownership, resolving long-standing industry concerns in which artists and labels have not been fully acknowledged.

Career Transition

Banking

When it comes to blockchain in the financial industry, it will be of the hybrid variety. In this case, people’s data must be made public so that all information can be shared, but access to blockchain banking must be limited to a single bank and all of its branches.

The blockchain is only associated with trusted nodes in this form of application, and the nodes must have access to the blockchain. The blockchain is shared and only trusted nodes have access to it.

Food industry

The food industry’s vast network, from farmers to grocers, makes it difficult to trace down food-borne diseases. Blockchain can increase the openness and efficiency of determining what food is tainted and where it is contaminated across the supply chain.

How Blockchain is changing the world?

The first significant innovation in blockchain technology occurred in the early 1980s. Blockchain technology was first created to allow the digital movement of money. However, in recent years, the blockchain has been acknowledged as a solid technology that can be applied to a wide range of applications.

The blockchain is a distributed ledger that is kept up to date by a network of computers. This distributed ledger enables numerous parties to record transactions without the requirement for centralized authority. The blockchain is a transparent ledger, which means that once it is recorded, it cannot be modified. Once a transaction is recorded on a blockchain, it cannot be changed.

One of the most important characteristics of the blockchain is that it functions on a trustless paradigm. Because the blockchain is dispersed across several computers, trust between the persons participating in a transaction is not necessary. As a result, the blockchain removes the possibility of fraud or identity theft.

Synopsis

By offering a safe, decentralized way of data exchange and storage, blockchain technology has the capability to completely transform a wide range of sectors. However, it should be remembered that the potential applications of blockchain technology are yet largely unexplored, and it could take some years before its true capacity is realized.
