Today, technology is scaling newer heights of success at an unbelievably fast pace. The newest triumphs in this direction may be the evolution of the NETWORKING. The brand new technology has greatly influenced the finance sector. In reality, it was initially produced for Bitcoin - the digital currency. However, it finds its application in a number of other things as well.

Coming across to this point was probably easy. But, you are yet to be aware what is Blockchain?


A distributed database

Imagine an electronic spreadsheet, which is copied umpteen variety of times across some type of computer network. Now, think about the computer network was created so smartly it regularly updates the spreadsheet alone. This is a broad breakdown of the Blockchain. Blockchain holds information as a shared database. Moreover, this database gets reconciled continuously.

This method has its own benefits. It does not allow the database being stored at any single location. The records inside it possess genuine public attribute and could be verified quickly. As there is no centralised version of the records, unauthorised users have no means to manipulate with and corrupt the information. The Blockchain distributed database is simultaneously hosted by an incredible number of computers, making the data easily accessible to just about anyone over the virtual web.

To help make the concept or even the technology clearer, it is a good idea to discuss the Google Docs analogy.

Google Docs analogy for Blockchain

Following the advent of the eMail, the conventional method of sharing documents is always to send a Microsoft Word doc as attachment to some recipient or recipients. The grateful recipients will take their sweet time to go through it, before they send back the revised copy. Within this approach, you should wait till receiving the return copy to find out the changes built to the document. Such things happen because the sender is locked out from making corrections till the recipient is done with the editing and sends the document back. Contemporary databases do not let two owners access the same record concurrently. This is how banks maintain balances of the clients or account-holders.

As opposed to the set practice, Google docs allow the parties to access the same document at the same time. Moreover, it also allows to view a single sort of the document to both simultaneously. As being a shared ledger, the Google Docs also behaves as a shared document. The distributed part only becomes relevant when the sharing involves multiple users. The Blockchain technologies are, in a way, an extension cord of this concept. However, you should point out here the Blockchain is not meant to share documents. Rather, it is only an analogy, which supports to have clear-cut understanding of this cutting-edge technology.

Salient Blockchain features

Blockchain stores blocks of information across the network, that are identical. Due to this feature:

The info or information can't be controlled by single, particular entity. There can not be no single failure point either. The data is hold inside a public network, which ensures absolute transparency in the overall procedure. The info stored in it wouldn't be corrupted. Demand for Blockchain developers

As stated earlier, Blockchain technology has a very high application in the realm of finance and banking. Based on the World Bank, more than US$ 430 billion money transfers were sent through it just in 2015. Thus, Blockchain developers have significant demand in the market.
