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 had been initially developed for Bitcoin – 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 learn what is Blockchain?
A distributed database
Imagine an electronic spreadsheet, which is copied umpteen number of times across a 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 inside it possess genuine public attribute and may be verified very easily. As there is 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 easy to get at to almost anyone over the virtual web.
To help make the concept or the technology clearer, it is just a good idea to discuss the Google Docs analogy.
Google Docs analogy for Blockchain
After the advent of the eMail, the conventional way 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 needs to wait till receiving the return copy to see the changes made to the document. This is really 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 simultaneously. This is one way banks maintain balances of their clients or account-holders.
In contrast to the set practice, Google docs allow both parties to access the same document concurrently. Moreover, it also allows to view a single 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 once the sharing involves multiple users. The Blockchain technology is, in ways, an extension of this concept. However, you should explain here that the Blockchain is not designed to share documents. Rather, it is just an analogy, which can only help to have clear-cut idea relating to this cutting-edge technology.
Bitcoin Revolution Review of information across the network, which are identical. By virtue of the feature:
The data or information can’t be controlled by any single, particular entity.
There can’t be no failure point either.
The info 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 stated earlier, Blockchain technology has a very high application in the wonderful world of finance and banking. Based on the World Bank, more than US$ 430 billion money transfers were sent through it only in 2015. Thus, Blockchain developers have significant demand on the market.
The Blockchain eliminates the payoff of the middlemen such monetary transactions. It was the invention of the GUI (Graphical User 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.
