Before moving further, let us first understand What is Blockchain Technology, its significance, its impact and decentralization.

What is Blockchain?

Blockchain is defined as:

“The Blockchain technology is a decentralized record that tracks exchanges that happens over a distributed system. This innovation permits members from over the system to affirm their exchange without the requirement for a central authority, this incorporates cash exchanges, casting vote, and trade settling and many more.”

In the context when we talk about “Block” and “chain”, we are referring to the computerized data (the “Block”) that is stored in a public database (“the chain”).

How it works?

If someone demands for a transaction, this transaction is then communicated to a P2P arrange that comprises of PCs which are known as nodes. The purpose of these nodes is to approve the transaction and the status of the client using algorithms. Now, this validated transaction can include either cryptocurrency, records, transactions or any sort of other data. This confirmed transaction is then joined with the other different transaction that make another block of data. Now, to the existing blockchain this block of data is added. This Blockchain cannot be changed and it is permanent.

Importance and Application

Indeed, when it comes to the latest technology, it’s certain that nobody wants to fall behind the competitors. Blockchain has been the talk of town, and most organizations are moving towards it to improve their plan of action, installment techniques and distributed storage and so forth.

The importance of Blockchain


Information breach and data stealing is one of the major concerns while operating in the digital world. Through Blockchain technology, the data stored has robust security which makes it impossible for one to hack.


Blockchain is less costly than most of the traditional financial model available in the market.

The blockchain convention would likewise keep up transparency in the constituent procedure, diminishing the work force expected to conduct an election and give the authorities results instantly.


While there are many upsides to the blockchain, there are additionally critical difficulties to its reception. The barriers to the use of blockchain technology today are not just technical. The genuine difficulties are political and administrative, and the large number of hours required for custom programming plan and back-end programming to coordinate blockchain to current business systems. The other shortcomings include technology cost required for operation, central bank concerns regarding the validation of cryptocurrency etc.

Road ahead

With the utilization of technology, there is so much that we can achieve together. But it is also important to not overlook that people are the at the focal point, all things considered.

Proposed in 1991 as a research project, blockchain is serenely subsiding into its late twenties. Like most recent college grads at its age, blockchain has seen a considerable amount of open examination in the course of the most recent two decade, with organisation around the globe theorizing about what the technology is prepared to do and where it’s going in the years to come.
