Blockchain Technology : The new era of technology

The New Era of Technology – Blockchain Technology


The new era of technology Block Chain technology is a collection of blocks linked with each other ,strongly resistant to alteration and protected through cryptography. Blockchain is a decentralized ledger of all transactions across peer-to-peer network.

You must have heard about the terms like cryptocurrency, bitcoins, digital gold, Ethereum, these terms are existing as a consequence of the Blockchain Technology. You might have wondered about What is Blockchain Technology, how and when it came into existence, who invented this technology,How does it works, what are the applications, what is the Future of Blockchain, how much this technology is reliableIt not only performs transactions but also ensures anonymity and security of the users.

Let’s have detailed information about Blockchain Technology. I hope that you will not have any unanswered question in your mind at the end of this article.


What is Blockchain Technology?

Blockchain Technology is a decentralized, immutable database that allows simultaneous access, validation, and updating record with an immutable manner over a network that is spread across multiple sites. This technology came in the 90’s but was first implemented in 2009 by Bitcoin. Blockchain provides secure functioning of decentralized database

A lot of times people get in a dilemma while using the terms Blockchain and Digital Ledger Technology (DLT), but they both have the same definition with different names. These terms are used interchangeably at different times.  It’s also known as distributed ledger technology (DLT), which means that all the transactions are recorded on a shared database that is accessible by everyone involved. For instance, financial online transactions from one person to another can be completed with the help of Blockchain Technology.

The data of the blockchains is chronologically consistent as chains cannot be removed or changed without network approval. As a result, this technology can be used to create immutable ledgers to track orders, payments, accounts, and other transactions. The system has built-in mechanisms to prevent fraudulent transaction entries and provide a consistent picture of those transactions.

Blockchain helps with verification and traceability of multi-stage transactions that require verification and tracking. You can provide secure transactionsreduce compliance costs, and speed up data transfer processes. Blockchain technology can support contract management and verify product provenance. It can also be used in voting platforms, manage titles and deeds.

History Of Blockchain Technology 

Today Block Chain is a buzz world. In 1990, the concept of distributed ledger came into existence. however, in 2009 Satoshi Nakamoto introduced the concept of Block Chain Technology to the world. In 2011-2012 the cryptocurrencies started to be deployed in applications. This allowed cryptocurrencies to be used for currency transfer and digital payment systems. Accordingly, since then bitcoin had shown multi-fold growth in its value. In 2013-2014 financial markets and applications started using blockchain beyond cash transactions. It allowed people to send money across borders, internationally without central authorities such as banks with no failure or fraud. Thus, blockchain came to the forefront with various business opportunities, research, applicability, and potential growth. In 2014, leading to the evolution of blockchain, give rise to contracts like smart contracts and permissioned blockchain network solutions. These Blockchain concepts are being used across various industry sectors for market development and exploration .such as  banking, health, retail sectors, and many more.

Block Chain as a technology can do much more. It not only performs transactions but also ensures anonymity and security of the user.  The block in block chain holds data whereas chain is a public database. It is a decentralized system consistently involving public ledger of digital records. It is popular because it brings trust, peer-to-peer networks and offers Genuine privacy protection. Block Chain technology has opened up new opportunities for block chain developers. Block chain has the potential to disrupt major industries like finance, health care , real estate and many more. . Blockchain is an innovative new way to store data in the form of blocks which ultimately lead to formation of chain . It is now being currently being used in making smart contracts that has been growing in popularity over the past few years.

How Blockchain Technology Works?

In a Blockchain, there are vast amount of blocks that are linked to each other. All the data is stored and recorded in these blocks. These blocks form a data chain as assets move from one place to another or change ownership. Blocks ensure the exact timing and order of transactions, and blocks are safely combined to prevent modification of blocks or insertion of blocks between two existing blocks.

Each transaction in the blocks is recorded as a “data block“. These transactions represent the movement of tangible (products) or intangible (intellectual) assets. Data blocks can record selected information: who, what, when, where, how much, and even the status of food shipments such as temperature.

Transactions are blocked together in an irreversible chain. This prevents the blockchain from being tampered with and provides the key strength of immutability. This eliminates the possibility of tampering by malicious actors and creates a ledger of transactions that you and other network members can trust. Block chain ensures data cannot be altered by any of the user within the network. with the help of Public  Distributed Ledger, proof of work and proof of stake and hash encryption.

Types of Blockchain

There are four different types of Blockchain Technology:

  1. Public Blockchain 
  2. Private Blockchain
  3. Hybrid Blockchain
  4. Consortium Blockchain

Let’s see in brief what are these different types of Blockchain Technology.

Private Blockchain

Private blockchains operate on closed networks and are generally suitable for private companies and organizations. Enterprises can use private blockchains to customize access and authorization settings, network parameters, and other key security options. A Private Blockchain Network cannot be access by any organization unless that organization has required authorities.

Public Blockchain

Bitcoin and other cryptocurrencies originate from public blockchains that have also helped popularize distributed ledger technology (DLT). Public blockchains also help eliminate certain challenges and problems such as security vulnerabilities and centralization. With DLT, data is distributed across a peer-to-peer network instead of being stored in one place. Consensus algorithms are used to verify the reliability of information. The most common example of this network are Proof of Stake (POS) and Proof of Work (POW).

Hybrid Blockchain

A Hybrid blockchain is a combination of public and private blockchain networks. T is also knowns as protected Blockchain Network. This Blockchain Network  is a private blockchain that grants special access to authorized individuals. This provides a better structure for assigning users and transactions that can join the network.

Consortium Blockchain

Like Hybrid blockchains, consortium blockchains have both public and private components, except that multiple organizations control a single consortium blockchain network. These types of blockchains can be more complex to set up initially, but once they are running they can offer greater security. In addition, consortium blockchains are ideal for collaborating with multiple organizations.

Advantages of Blockchain technology

Blockchain has vast amount of benefits in real world, number of businesses are running today due to Blockchain Technology. Some of the most popular advantages of Blockchain Technology are described below:


Blockchain creates trust within different organizations where trust does not exist or is not proven. As a result, the organizations can exchange data willingly else they need to fulfill other requirements for intermediaries to share data with each other which may or may not be as trustworthy as Blockchain. Cryptocurrencies are the most common example of people trusting each other while they have not seen anyone in the real world.

Decentralized Structure

Blockchain enables data sharing within a business ecosystem where no single entity is solely responsible. In a decentralized blockchain network, you don’t need to know or trust anyone else. All members of the network have the exact same copy of the data in the form of a distributed ledger. If a member’s ledger is altered or corrupted in any way, it will be rejected by the majority of members on the network.


The security of blockchain-enabled systems is another key advantage of this new technology. The increased security that blockchain offers stems from how the technology actually works. The blockchain creates an immutable record of transactions using end-to-end encryption that eliminates fraud and cheating. Additionally, blockchain data is stored across a network of computers, making it nearly impossible to hack (unlike traditional computer systems, which store data collectively on servers). Additionally, blockchain can address privacy concerns better than traditional computer systems by anonymizing data and requesting permissions to restrict access.


Immutability signifies when one transaction is recorded, it cannot be altered or deleted unless the majority of the nodes on the system agree to do so. With blockchain, every transaction is dated and time stamped, leaving a permanent record. Blockchain can therefore be used to track information over time, allowing secure and reliable auditing of information.

Applications of Blockchain Technology

To make you understand blockchain in a more better way, here are the real world uses of Blockchain.

Money Transfer

Driven by Bitcoin, cryptocurrency transfer applications are very popular right now. Blockchain is especially popular in finance because it saves money and time for financial companies of all sizes. By reducing red tape, real-time ledger systems, and reducing third-party cost, blockchain could save big banks millions of dollars. These companies use blockchain to efficiently to transfer money from one entity to another entity.

Smart Contracts

Smart contracts are similar to regular contracts, but contract rules are applied in real-time on the blockchain, eliminating middlemen and adding a level of accountability to all parties in a way traditional contracts cannot. The difference is that this saves companies time and money while ensuring compliance with all regulations.

Blockchain-based contracts are growing in popularity as sectors such as government, healthcare and real estate discover their benefits. Below are some examples of how businesses can use blockchain to make contracts smarter.

Sharing Medical Information

By storing medical records on the blockchain, doctors and medical professionals can obtain accurate and up-to-date information about their patients. This ensures that patients who see multiple physicians receive the best possible care. It can also speed up medical record retrieval systems, enabling more timely treatment in some cases. And with insurance information stored in the database, doctors can easily verify that their patients are insured and their treatment covered.

Secure IoT Networks

The Internet of Things (IoT) makes our lives easier, but it also opens the door for malicious actors to access our data and control our critical systems. Blockchain technology can provide greater security by storing passwords and other data on a decentralized network rather than on central servers. Additionally, since blockchains are effectively immutable, they provide protection against data manipulation.
