In an ever-changing world, Charles Darwin’s theory of “survival of the fittest” is still apt. We as humans continue to thrive, and it is in our DNA to stay ahead of the curve, stay competitive. During this moment of COVID-19 pandemic, when the world is being reset by the new normal of social distancing.  We would like to bring the focus of individuals and businesses about the need to transform using the latest and cutting edge Blockchain technology.

With the invention of Bitcoin in 2008, came along the “Blockchain Technology,” which was the backbone of this new cryptocurrency system. It was the record-keeping technology based on distributed, decentralized, and public ledger. The technology can be described as a chain of blocks of information. Each block carries three key digital pieces of information.

  • Information about the transaction like date, time, the value of the transaction
  • Information about the parties involved in the transaction
  • Unique “hash” or cryptographic code to distinguish one transaction from another

Alright, we understand that Blockchain is an information chain containing transactions, but who creates it, who stores it, and how can we check it. So let’s take a quick deep dive into its working with five simple steps:

  • A transaction is requested
  • Information of this transaction is pushed via Peer to Peer network to each node
  • Each node validates the transaction using an algorithm
  • Approved transactions are represented as blocks of data and added to “public” ledger
  • Block is added to the existing chain of transactions and its permanent

Blockchain Benefits for Businesses

Every shareholder wants to own shares of a business that is competitive, sustainable, and profitable. With the latest lockdown measures due to COVID19 being implemented all across the world, as a business owner, we are interested in understanding what strategy is best to align, transform, and grow to maintain the competitive edge and stay ahead of the curve. There are two ways of approaching this, one by reducing cost and other by increasing revenue. Blockchain technology can be deployed to ensure profitability, but where do we invest my money to achieve this. Let’s take a look at the picture below showing the advantages of Blockchain technology.


With a quick look at the picture, we can already see how the cost of operations can be easily reduced by implementing Blockchain technology.

  • Reduced transaction cost by removal of trusted 3rd party intermediaries
  • Fraud prevention and more secure due to consensus, encryption and linked to the previous information block
  • Reduced cost due to automation of the operations

To see how the revenue can be improved using the Blockchain Technology, let’s review the latest study performed by Boston Consulting Group & Cisco on “Stamping out counterfeit goods with Blockchain and Internet of Things (IoT).” This study evaluated the impact of combining Blockchain technology with IoT to prevent counterfeiting, where 60-80% of the counterfeit sales were reduced. This reduction in counterfeit sales results in approx. 3.85% increase in revenue, with the total net benefit ranging from 2% to 5% of revenue.

Based on the above study and analysis, a business can implement Blockchain technology not just to reduce costs but also to increase revenue. To understand the application of this technology, we can review the value at stake figures across the top sectors.
