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 may be the evolution of the Blockchain technology. The brand new technology has greatly influenced the finance sector. Actually, 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 know what is Blockchain?

A distributed database

Imagine an electronic spreadsheet, which is copied umpteen number of times across some type of computer network. Now, imagine the computer network is designed 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 quickly. As there is no centralised version of the records, unauthorised users have no methods to manipulate with and corrupt the info. The Blockchain distributed database is simultaneously hosted by millions 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 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 made to the document. This happens because the sender is locked 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 how banks maintain balances of these 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 see an individual 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, it is important to point out here that the Blockchain is not designed to share documents. Rather, it really 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 across the network, which are identical. By virtue of this 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 entire procedure.
Bitcoin Revolution Official 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. 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 type of desktops. Similarly, the wallet application may be the most common GUI for the Blockchain technology. Users utilize the wallet to buy things they want using Bitcoin or any other cryptocurrency.
