An Introduction to the Blockchain Technology for the Beginners

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 brand new technology has greatly influenced the finance sector. In fact, it had been initially developed for Bitcoin – the digital currency. However now, it finds its application in a number of 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, 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 summary 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. The records inside it possess genuine public attribute and may be verified very easily. As there is no centralised version of the records, unauthorised users have no means to manipulate with and corrupt the info. The Blockchain distributed database is simultaneously hosted by an incredible number of computers, making the data easy to get at to almost anyone across the virtual web.

To help make Bitcoin Era Official or the technology clearer, this is a good idea to go over the Google Docs analogy.

Google Docs analogy for Blockchain

After the advent of the e-mail, the conventional way of sharing documents is to send a Microsoft Word doc as attachment to a recipient or recipients. The recipients will take their sweet time to proceed through it, before they send back the revised copy. In this process, one needs to wait till receiving the return copy to see the changes designed to the document. This is really because the sender is locked 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 concurrently. This is how banks maintain balances of their clients or account-holders.

In contrast to the set practice, Google docs allow both the parties to access the same document as well. 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 the 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 concerning this cutting-edge technology.

Salient Blockchain features

Blockchain stores blocks of information across the network, which are identical. By virtue of this feature:

The data or information can’t 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 stated earlier, Blockchain technology has a very high application in the world of finance and banking. According to the World Bank, 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 User Interface), which facilitated the normal man to access computers in form 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 want using Bitcoin or any other cryptocurrency.
