What is Blockchain Technology? Where is it Used?


Blockchain technology and digitalization is an innovative database technology at the core of almost all cryptocurrencies. Blockchain makes it extremely difficult to hack the system or cheat it by distributing identical copies of a database over an entire network. Blockchains can store information about cryptocurrency transactions, NFT ownership, and Defi intelligent contracts.

It is entirely decentralized. Instead of being kept in one place by a central administrator (think Excel spreadsheets or bank databases), many identical copies of a blockchain database are stored on different computers distributed across the network. These computers are called nodes.

Blockchain technology can be used for many purposes, including financial services and voting system administration.


Blockchain is used most often today as the backbone for cryptocurrencies like Bitcoin and Ethereum. Blockchain records transactions that occur when people exchange, buy or spend cryptocurrency. Blockchain could be more widely used as cryptocurrency is more popular.

Coins are volatile and aren’t used often to buy goods or services. This is changing; however, like PayPal, Square, and money, other services businesses make digital assets services widely available to vendors and customers.


Blockchain is used to facilitate transactions in fiat currencies, such as dollars and euros, beyond cryptocurrency. Because transactions can be verified faster and processed outside of business hours, it could be quicker than sending money through banks or other financial institutions.

Asset Transfers

Blockchain could be used to transfer ownership of real-life assets such as vehicles and deeds to real estate. Both parties would use the Blockchain first to verify ownership and money. Then they could record and complete the sale on the Blockchain. This process allows them to transfer the property deed electronically without having to go through any type of paperwork.

Smart Contracts

Self-executing contracts, also known as “smart contracts,” are another blockchain innovation. These contracts can be automatically enacted once certain conditions are met. Payment for a product might be made instantly if the seller and buyer have met all the requirements. Smart contracts have great potential. Blockchain technology and coded instructions can be used to automate legal contract processing. A properly coded innovative legal agreement on a distributed ledger could reduce or even eliminate the need for third parties to verify performance.

Supply Chain Monitoring

As goods travel from one region to another, supply chains can contain a lot of information. It can be challenging to track down the source of problems with traditional data storage methods. For example, which vendor made poor-quality goods? This information could be stored on Blockchain to make it easier for you to trace the source of problems, like which vendor’s poor-quality goods came from.


Experts are investigating the ways to use blockchain technology and digitalization to stop fraud in voting. Using Blockchain in the poll could allow voters to cast votes that can’t be altered and would eliminate the need for people to verify paper ballots manually.
