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. In fact, it had been initially developed for Bitcoin – the digital currency. However now, it finds its application in a number of 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 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 summary 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 may be verified quickly. As there’s no centralised version of the records, unauthorised users haven’t any methods to manipulate with and corrupt the info. The Blockchain distributed database is simultaneously hosted by an incredible number of computers, making the data easily accessible to almost anyone across the virtual web.
To help make the concept 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 method of sharing documents would be to send a Microsoft Word doc as attachment to a recipient or recipients. The recipients will take their sweet time to proceed through it, before they send back the revised copy. In this approach, 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 done with the editing and sends the document back. Contemporary databases do not allow two owners access exactly 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 parties to access the same document concurrently. 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 important to explain here that the Blockchain is not meant to share documents. Rather, it is just an analogy, which can only help to have clear-cut idea concerning this cutting-edge technology.
Bitcoin Era Site of information over the network, that 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 single failure point either.
The info is hold in a public network, which ensures absolute transparency in the entire procedure.
The data stored inside 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. According to 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 in such monetary transactions. It had been the invention of the GUI (Graphical INTERFACE), which facilitated the common man to access computers in form of desktops. Similarly, the wallet application may be the most typical GUI for the Blockchain technology. Users utilize the wallet to buy things they need using Bitcoin or any other cryptocurrency.
