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 had been initially developed for Bitcoin – the digital currency. However now, it finds its application in a number of other things as well.

Coming across 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 a computer network. Now, imagine the computer network was created so smartly that it regularly updates the spreadsheet on its own. 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 in it possess genuine public attribute and can be verified very easily. As there’s no centralised version of the records, unauthorised users haven’t any means to manipulate with and corrupt the data. The Blockchain distributed database is simultaneously hosted by an incredible number of computers, making the data easy to get at to almost anyone over the virtual web.

To help make the concept or the technology clearer, it is a good idea to discuss 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. Bitcoin Era 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 made 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 do not allow two owners access the same record concurrently. 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 concurrently. Moreover, it also allows to view an individual version of the document to both of these 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 ways, an extension of this concept. However, it is important to explain here that the Blockchain isn’t designed to share documents. Rather, it really is just an analogy, which can only help to have clear-cut idea relating to 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 failure point either.
The data is hold in a public network, which ensures absolute transparency in the overall procedure.
The data stored inside it cannot be corrupted.
Demand for Blockchain developers

As mentioned earlier, Blockchain technology includes a very high application in the wonderful world of finance and banking. Based on 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 in such monetary transactions. It was the invention of the GUI (Graphical INTERFACE), which facilitated the common man to access computers in form of desktops. Similarly, the wallet application is the most common GUI for the Blockchain technology. Users make use of the wallet to buy things they want using Bitcoin or any cryptocurrency.
