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 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 amount of times across some type of computer network. Now, imagine the computer network was created so smartly that it regularly updates the spreadsheet on its own. 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 benefits. It does not allow the database to be stored at any single location. The records in it possess genuine public attribute and will be verified very easily. As there’s no centralised version of the records, unauthorised users have no means to manipulate with and corrupt the data. The Blockchain distributed database is simultaneously hosted by millions of computers, making the data easy to get at to almost anyone across the virtual web.

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

Google Docs analogy for Blockchain

After the advent of the eMail, the conventional way of sharing documents is 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 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 done with the editing and sends the document back. Contemporary databases don’t allow two owners access the same record concurrently. This is one way banks maintain balances of these clients or account-holders.

In contrast to the set practice, Google docs allow both parties to access exactly the same document concurrently. Moreover, it also allows to see 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 once the sharing involves multiple users. The Blockchain technology is, in a way, an extension of this concept. However, you should point out here that the Blockchain is not meant to share documents. Rather, it really is just an analogy, which can only help to have clear-cut idea about this cutting-edge technology.

Salient Blockchain features

Blockchain stores blocks of information across 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 failure point either.
The data 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 has a very high application in the world of finance and banking. According to 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 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 common man to gain access to computers in type 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 want using Bitcoin or any cryptocurrency.
