An Introduction to the Blockchain Technology for the Beginners

These days, technology is scaling newer heights of success at an unbelievably fast pace. One of the latest triumphs in this direction is the evolution of the Blockchain technology. The brand new technology has greatly influenced the finance sector. In fact, it was 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 learn what is Blockchain?

A distributed database

Imagine an electronic spreadsheet, that is copied umpteen number of times across some type of 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 own benefits. It does not allow the database to be stored at any single location. Bitcoin Evolution inside it possess genuine public attribute and will be verified very easily. As there is no centralised version of the records, unauthorised users have no methods 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 across the virtual web.

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

Google Docs analogy for Blockchain

After the advent of the e-mail, the conventional method of sharing documents would be to send a Microsoft Word doc as attachment to a recipient or recipients. The recipients will take their sweet time to go through it, before they send back the revised copy. In this approach, one must wait till receiving the return copy to see the changes designed to the document. This happens because the sender is locked out from making corrections till the recipient is performed with the editing and sends the document back. Contemporary databases don’t allow two owners access the same record at the same time. This is one way banks maintain balances of their clients or account-holders.

In contrast to the set practice, Google docs allow both parties to access the same document as well. Moreover, it also allows to view an individual version of the document to both of these simultaneously. Just like 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 ways, an extension of the concept. However, you should point out here that the Blockchain isn’t meant to share documents. Rather, it is just an analogy, which can only help to have clear-cut idea concerning 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 single failure point either.
The info is hold in a public network, which ensures absolute transparency in the overall procedure.
The data stored in it cannot be corrupted.
Demand for Blockchain developers

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

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