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. Click here 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 was created so smartly that it regularly updates the spreadsheet alone. 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 own benefits. It does not allow the database to be stored at any single location. The records in it possess genuine public attribute and may be verified quickly. As there is 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 make the concept or the technology clearer, it is a good idea to discuss the Google Docs analogy.
Google Docs analogy for Blockchain
After the advent of the e-mail, 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 approach, one must wait till receiving the return copy to start to see the changes made to the document. This is really because the sender is locked out from making corrections till the recipient is performed with the editing and sends the document back. Contemporary databases do not allow two owners access exactly the same record at the same time. This is one way banks maintain balances of these clients or account-holders.
As opposed to the set practice, Google docs allow both the parties to access the same document at the same time. Moreover, it also allows to see 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 when the sharing involves multiple users. The Blockchain technology is, in a way, an extension of this concept. However, it is very important explain here that the Blockchain isn’t designed to share documents. Rather, it is just an analogy, which will help to have clear-cut idea about this cutting-edge technology.
Salient Blockchain features
Blockchain stores blocks of information over the network, which are identical. By virtue of this 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 world of finance and banking. In line with 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 on the market.
The Blockchain eliminates the payoff of the middlemen in such monetary transactions. It had been the invention of the GUI (Graphical User Interface), which facilitated the normal man to gain access to computers in form of desktops. Similarly, the wallet application is the most typical GUI for the Blockchain technology. Users utilize the wallet to buy things they want using Bitcoin or any cryptocurrency.
