Blockchain has been around since the early 1990s and has had a significant impact on how digital currencies function. A blockchain is a type of public ledger that aims to make crypto currency operate in the digital world. As it matures, blockchain technology has proven to be one of the most significant breakthroughs of the twenty-first century, widening the notion of currency payments and improving the financial industry.


From industry to technology, bitcoin can be found everywhere, and with it, the appeal of blockchain. Not only is blockchain history diversified, but it also contains a large number of undiscovered information, which may be useful for potential investors today. It is important to examine the history and fundamental components of the blockchain sector in order to comprehend it.


The word “blockchain” refers to a distributed database that is shared by several network nodes. Data is saved digitally using this unique technology, which is well-known for its role in bitcoin. From public security to decentralised transaction records, the sector ensures the protection of digital data and enables an increasing number of individuals to utilise blockchain. The key criteria are security and digital upkeep, and blockchain does not rely on any third party.


The Initial Stage –

The earliest stage was built in 1991 by research scientists Stuart Haber and W. Scott Strornetta on the premise of introducing a feasible solution based on computer technology for time-stamping online documents in order to avoid backdating and manipulation. This system is built on a “cryptographically safe chain of blocks” that enables the storing of time-stamped documents.

The key reason for this early step was the early popularity and public use of blockchain. Hal Finney, a cryptography activist and computer scientist, then proposed “Reusable Proof of Work (RPoW)” – a system that functions as a prototype for online currency. The system operated on the basis of non-transferable and non-fungible Hashcash-based work tokens. This early but crucial move in 2004 promoted the solution of the double-spending problem by requiring token ownership registration only on a trusted gateway.

Users might utilise RPoW to validate correctness and integrity in real-time. The next year, Merkle Trees brought the inclusion of a design. Merkle introduced the notion of “enabling many documents collecting in a single block” in 1992, making blockchain considerably more efficient. A secure chain of blocks with connected data series was built.

Despite the fact that this technology was retired in 2004, the most recent record contained the whole chain’s history. Again, blockchain sprang to prominence in 2007 when Satoshi Nakamoto presented the notion of “bitcoin” as a decentralised type of digital money, which has remained popular to this day.

Satoshi not only invented distributed blockchain theory, but he also improved it by adding blocks to prior chains without the knowledge of any other party. For verification, a peer-to-peer network was employed, with no central authority assuming control of the operation. Through these early phases of development by Satoshi and other prospective activists and scientists, blockchain is referred to as the backbone of bitcoin.

The Three Phases Of Blockchain Advancement 

Phase 1: Blockchain Version 1.0

Year: 2008 -2013

When Bitcoin was first presented to the market, Satoshi published a whitepaper outlining its potential and underlying principles. Several previous blocks were mined through to form the genesis block, resulting in the biggest chains of connected blocks storing numerous data and transactions. Following that, the currency’s value skyrocketed, as did blockchain’s full potential.

Phase 2: Blockchain Version 2.0

Year: 2013-2015

Also known as the “ethereum early stages of development,” top developer Vitalik Buterin saw bitcoin’s limitations and saw the necessity to introduce a new type of cryptocurrency. Ether, the largest blockchain application with smart functionalities and a greater transaction rate, was developed in 2015 to accelerate the process and strengthen bitcoin.

Phase 3: Blockchain Version 3.0

Year: 2015-2018

New blockchain apps such as NEO, IOTA, and others were introduced. NEO was introduced in China, and to speed development, IOTA entered the market, propelling the industry to new heights.

Phase 4: Blockchain Version 4.0

Year – 2020

With a promising future, blockchain has gained in popularity among experts as large investors seek out new technologies, upgrading
