Blockchain, in its most basic definition, is a data storage file that is replicated (spread out) over a network of computers (decentralized).

To get into the nitty-gritty, the blockchain is based on peer-to-peer network technology, meaning that the network as a whole is made up of users, or “peers” (or nodes). Every transaction made in the network is verified and recorded by every peer in the network. This implies that each peer’s ledger is updated whenever a new transaction is introduced to the network after verification. Distributed ledger technology refers to this method of recording transactions independently (DLT).

How Blockchain Technology Work

Specific software must be developed for blockchain technology to function. This code enables a distributed network of computers to be built, which will in turn operate the blockchain. The same can be said of the code that powers Bitcoin and other cryptocurrencies. This software is often free and open-source (FOSS) licensed. This means that anybody is free to access them, utilize them, and provide feedback and contributions.

A blockchain-type network is considered decentralized since it does not rely on a central database or server. This implies that all of the computers in the globe that are linked to the same blockchain have a copy of the same information. We may argue that a blockchain network is decentralized if more than half of the machines making up that network do not belong to the same individual or firm. This means there is no one point of origin for its emissions, controls, or powers.

A blockchain network is really simply a distributed database that can store and update information. All this, with no ability to alter its current state. It uses extremely complex mathematics to create interconnected networks amongst the many records it stores. This eliminates the possibility of including a record that is inconsistent with the others.

Types of Blockchain

There are four distinct varieties of blockchain. Let’s break them down, one by one:

Public Blockchain

Private Blockchain

Hybrid Blockchain

Consortium Blockchain

1) Public Blockchain – One type of blockchain, known as a public blockchain, is totally accessible to the decentralized model. Since there are no barriers to entry, anybody with a computer and access to the internet may take part in the system.

Just like its name suggests, this blockchain is accessible to everyone and belongs to no one in particular.

Everyone with access to the internet and a reasonably powerful computer can join this public blockchain.

Every computer in the network stores a replica of every other node and block in the system.

We may check the legitimacy of a transaction or a record by using this public blockchain.

2) Private Blockchain- Private blockchains are more secure than public blockchains since only authorized nodes may take part in the ledger’s transactions.

Unlike a public blockchain, they are kept more secret.

Only those with proper access can utilize them.

Private networks run these blockchains.

In such a scenario, only a select group of employees or members of a group are permitted to join a private network.

3) Hybrid Blockchain – Hybrid Blockchain combines private and public blockchains, with certain data being kept under lock and key by a single entity while other transactions are made public.

A hybrid of public and private blockchains.

Permissioned and permissionless systems are both in use.

Access data using smart contracts

In a hybrid blockchain, even though the principal entity controls the blockchain, it cannot change the transaction.

4) Consortium Blockchain – Consortium Blockchain is an innovative solution to the problems faced by the company. This blockchain is responsible for transaction verification and the initiation/receipt of transactions.

Often referred to as “Federated Blockchain,”

These steps are creative in their approach to meeting the requirements of the company.

Some of it is open to everyone, while some of it isn’t.

When there are several entities involved in the management of the blockchain, it is called a “multi-organizational blockchain

Blockchain Implementation

Blockchain technology has several applications, but Bitcoin is where it is most often known. To create bitcoin, the first decentralized digital money, the now-famous Satoshi Nakamoto devised blockchain technology.

Blockchain developed a workable solution to this issue by decentralizing the network and enabling it to be controlled and maintained by various nodes that are not even in the same geographical region.


Including a bitcoin API in your new app will increase revenue by appealing to bitcoin users, and it will help your business save money by reducing the costs associated with accepting bitcoin payments.


Smart contracts, promoted by groups like the Ethereum Project, provide businesses access to a vast array of resources that may be used to better their products. Contracts between two or more parties can be made legally binding with the use of smart contracts.


Another exciting use case for blockchain technology that many businesses are investigating right now is protecting Internet of Things (IoT) networks against unauthorized access. Through the Internet of Things, networks of intelligent devices may be networked to the user’s advantage.


The addition of a blockchain-based ID solution will not only increase the safety of your app but will also provide users peace of mind that their personal information is secure.

While this may not seem like a big selling point now, the recent spate of data breaches like the one that affected 50 million Facebook users in September 2018 (and resulted in some of the first-ever lawsuits in which users were given the right to sue the company for better security) has raised awareness about the critical need for ID security.


It is naive to assume that these problems with blockchain technology are not significant obstacles to its widespread use, especially given their sheer quantity and complexity. Most of blockchain’s biggest problems, though, are symptomatic of the normal growing pains of any novel technology. Proponents of blockchain technology will need to demonstrate a business case for adoption by convincing their firms to undertake analogous risks, develop comparable partnerships, and make comparable trade-offs in other business sectors.
