These days, technology is scaling newer heights of success at an unbelievably fast pace. Among the latest triumphs in this direction is the evolution of the Blockchain technology. The new technology has greatly influenced the finance sector. In fact, it had been initially developed for Bitcoin – the digital currency. But now, it finds its application in several other things as well.

Sounding this far was probably easy. But, one is yet to know what is Blockchain?

A distributed database

Imagine an electronic spreadsheet, which is copied umpteen amount of times across a computer network. Now, imagine the computer network was created so smartly that it regularly updates the spreadsheet alone. This is a broad overview of the Blockchain. Blockchain holds information as a shared database. Moreover, this database gets reconciled continuously.

This approach has its benefits. It does not allow the database to be stored at any single location. The records inside it possess genuine public attribute and will be verified very easily. As there is Bitcoin Era centralised version of the records, unauthorised users have no means to manipulate with and corrupt the data. The Blockchain distributed database is simultaneously hosted by an incredible number of computers, making the data easily accessible to almost anyone over the virtual web.

To help make the concept or the technology clearer, it is just a good idea to discuss the Google Docs analogy.

Google Docs analogy for Blockchain

After the advent of the eMail, the conventional way of sharing documents would be to send a Microsoft Word doc as attachment to a recipient or recipients. The recipients will need their sweet time to proceed through it, before they send back the revised copy. In this process, one must wait till receiving the return copy to see the changes designed to the document. This is really because the sender is locked out from making corrections till the recipient is done with the editing and sends the document back. Contemporary databases do not allow two owners access exactly the same record as well. This is one way banks maintain balances of their clients or account-holders.

In contrast to the set practice, Google docs allow both the parties to access exactly the same document at the same time. Moreover, it also allows to view a single version of the document to both of them simultaneously. As being a shared ledger, the Google Docs also acts as a shared document. The distributed part only becomes relevant when the sharing involves multiple users. The Blockchain technology is, in a way, an extension of this concept. However, you should explain here that the Blockchain isn’t meant to share documents. Rather, it is just an analogy, which will help to have clear-cut idea relating to this cutting-edge technology.

Salient Blockchain features

Blockchain stores blocks of information over the network, that are identical. By virtue of the feature:

The data or information cannot be controlled by any single, particular entity.
There can’t be no failure point either.
The info is hold in a public network, which ensures absolute transparency in the entire procedure.
The data stored in it cannot be corrupted.
Demand for Blockchain developers

As mentioned earlier, Blockchain technology has a very high application in the world of finance and banking. According to the World Bank, a lot more than US$ 430 billion money transfers were sent through it only in 2015. Thus, Blockchain developers have significant demand available in the market.

The Blockchain eliminates the payoff of the middlemen such monetary transactions. It was the invention of the GUI (Graphical INTERFACE), which facilitated the common man to gain access to computers in type of desktops. Similarly, the wallet application may be the most common GUI for the Blockchain technology. Users make use of the wallet to buy things they need using Bitcoin or any other cryptocurrency.
