What is Blockchain And When Was Blockchain Invented?

Blockchain is a peer-to-peer network where peers can communicate and do transactions with each other without the need for a centralized entity. To make the network self-sustained, each peer will have a copy of the ledger and there will also be a consensus algorithm that will take care of validating and storing transactions in blocks that are part of the “block-chain.”

So, if you want to send money to another person using a blockchain network, then you do not need to register for any service. 

All you need is a wallet that is capable of connecting to the blockchain network and initiating the transaction. Once done, the network will use its consensus algorithm to reach a consensus on the transaction, and finally adding to the block. 

The transaction becomes immutable once the block is added to the chain.

There are many benefits of blockchain, including:

  • Better transparency
  • Enhanced security
  • True traceability
  • Reduced cost
  • Improved speed and efficiency

And more!

From Centralization To Decentralization

Our work thrives on centralization. Almost every social media app you open on your computer is controlled by a company or a group of companies that provide the service in lieu of your data, even when they deny that they do not use your data for monetary benefits. If you close your computer screen off and go to your bank, then also you will find centralization at the core of almost every function.

And, why not? Centralization has been quite successful when it comes to globalization. The 21st century has brought together a plethora of inventions empowering businesses to globalize their market and take advantage of international treaties and collaboration that enables every business to be at the same level playing field.

The word centralization was first used in France in 1794. In 1820, the “decentralization” word was used for the first time.

In English, the centralization word came into existence in the 1800s.

As you can see, the concepts of centralization and decentralization are almost two centuries old. 

With centralization capturing a strong foothold on how the world worked, it was only time when people started to realize that there is a need for decentralization as well. In the early 20th century, American people responded negatively towards centralization; they blamed large-scale industrial production for destroying the small or medium scaled businesses.

There are multiple approaches to decentralization which are more akin to distributed nature.

Internet’s Journey In Respect To Centralization and Decentralization

The internet also saw the same cycle of change and growth when it comes to centralization and decentralization. When the internet first came up, everyone was almost convinced that it is decentralized. However, with the maximum amount of communication flowing through a number of corporations, it was understood that the internet is not truly decentralized. 

Soon, a lot of new projects started to surface that tried to solve the decentralization problem. Some of the projects include FreedomBox, Namecoin, ArkOS, and so on! All of these project’s focus was to make the internet more decentralized with time. 

E.F.Schumacher in his book, “Small is Beautiful: A Study of Economics As If People Mattered.”  used another term known as “appropriate technology.”  The term emphasized heavily on technologies that are small-scale yet energy-efficient and decentralized.

All of these lead to Blockchain technology.

The Rise of Blockchain Technology: When Was Blockchain Invented?

The idea of blockchain is not new. Stuart Haber and W.Scott Stornetta in 1991 also envisioned something similar to blockchain. They create their first cryptographically secure chains of blocks with timestamps so that no one can tamper them. 

In the very next year, Haber, Stornetta, and Bayer used Merkle trees to further refine the design. It improved the efficiency of the system and enabled them to store multiple document certificates in one block.

Then there is another interesting advancement that is related to cryptocurrencies with the underlying principle of a system that is similar to blockchain technology.


W.Dai, a well-known computer engineer with his major work in cryptocurrencies and cryptography, mentioned the idea of decentralized money, b-money in 1998. It is a scheme where the users can stay anonymous using their digital pseudonyms and also do transactions with each while enforcing contracts without the need for any help from outside.

This thought-process can be found on his site B-Money, he started his train of thoughts by mentioning that there is no need for government or violence in a community where people are linked without knowing their true identity.

His theory clearly mentioned that such a system is possible where a community can operate without being confined by rules and regulations of a single entity. The participants can co-operate between themselves and hence can use the community to drive the exchange of money and enforce contracts. 

He also cleverly mentioned two protocols where the first protocol was “everyone mountains there a database (separate).” The database will have a complete account of each pseudonym money, and hence everyone collectively knows the money ownership.

He theorized the need to solve computational problems where he mentioned is the creation of money.

Fascinating, right?

Well, the idea of cryptocurrencies was not new, and there have always been theories for it.

In 2008, a person named Satoshi Nakamoto(pseudonym) released the bitcoin whitepaper, which built upon the idea shared by W.Dai to create bitcoin. Bitcoin is the cryptocurrency here. However, the technology used by bitcoin is blockchain technology.

However, there is conflicting information online where few resources mention the year of blockchain technology in 2009 and others as 2008. We choose Wikipedia as it is more reliable than other online sources.

So, if you are asked when was blockchain invented? The answer should be 2008 and not 2009.

Blockchain Separates from Bitcoin

Bitcoin is a cryptocurrency that utilizes blockchain technology. That means it took some years before developers started to realize blockchain technology potential and started to use it apart from just creating cryptocurrencies. 

There are still many people who believe that bitcoin and blockchain are the same things.

But, in reality, bitcoin used blockcahin technology as its underlying tech.

Then came 2017, where the bitcoin demand surged and reached new heights. This enabled blockchain technology to reach new people and masses.

Blockchain Technology: The Journey Continues

Bitcoin’s underlying blockchain technology is the first-generation technology. This left a lot of scope for improvements in the blockchain technology.

Bitcoin Technological Struggle

One of the problems that it suffered from is the lack of speed to make transactions happen. The lack of scalability hampered bitcoin. But, now, bitcoin developers are already in the works to introduce a lightning network that improves the bitcoin transaction per second from 7 TPS to a respectable number.

VISA, on the other hand, offers 24000 transactions per second.

Bitcoin also suffers from transaction fees that can be quite taxing for the person who is doing the transaction.

However, the current scenario is changing fast as bitcoin is now testing out and deploying lighting networks.

The two components for their lightning network include the Lighting Network Daemon and Neutrino. The network’s heavy load is taken off-chain using the lightning network.

The Neutrino is a privacy-focused client that is easy to use and privacy-focused. The Lightning Network Daemon, on the other hand, is going to handle other aspects of the network.

Ethereum: Introducing Smart Contracts

The lack of perfection in bitcoin’s blockchain technology meant tons of opportunities for others to create blockchain technology that can be more flexible when it comes to scalability, compatibility, and configurability.

Ethereum was first released on 30th July 2015 by Vitalik Buterin and Gavin Wood. It introduced smart contracts that enabled developers to code conditions and requirements and create virtual contracts between two parties. 

So, if you buy a house from a seller, you both can create a self-executable smart contract that will have all the underlying conditions, including loan payment, transfer of ownership, and so on. Once you make all the payment, the smart contract will execute itself and pass the ownership to you from the seller.
