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. Actually, it was initially developed for bitcoin privacy– the digital currency. However 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, that is copied umpteen amount of times across some type of computer network. Now, imagine the computer network is designed 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 permit the database to be stored at any single location. The records in it possess genuine public attribute and can be verified quickly. 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 millions 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 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 is 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 needs to wait till receiving the return copy to start to see the changes designed to the document. This is really 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 concurrently. This is how banks maintain balances of these clients or account-holders.

As opposed to the set practice, Google docs allow both parties to access the same document at the same time. Moreover, it also allows to view an individual version of the document to both of them simultaneously. Just like a shared ledger, the Google Docs also acts as a shared document. The distributed part only becomes relevant once the sharing involves multiple users. The Blockchain technology is, in ways, an extension of this concept. However, it is very important point out here that the Blockchain isn’t meant to share documents. Rather, it really 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, that 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 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 Bitcoin Evolution Scam , 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 in such monetary transactions. It was the invention of the GUI (Graphical User Interface), which facilitated the normal man to gain access to computers in type 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 need using Bitcoin or any other cryptocurrency.
