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. 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?
Bitcoin Era Site distributed database
Imagine an electronic spreadsheet, which is copied umpteen amount of times across a computer network. Now, imagine the computer network is designed so smartly that it regularly updates the spreadsheet alone. 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 inside it possess genuine public attribute and may be verified quickly. 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 an incredible number of computers, making the data easily accessible to almost anyone over the virtual web.
To make the concept or the technology clearer, it is 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 take 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 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 performed with the editing and sends the document back. Contemporary databases do not allow two owners access the same record at the same time. This is one way banks maintain balances of their clients or account-holders.
As opposed to the set practice, Google docs allow both the parties to access the same document simultaneously. Moreover, it also allows to see 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 when the sharing involves multiple users. The Blockchain technology is, in ways, an extension of the concept. However, it is important to point out here that the Blockchain isn’t meant to share documents. Rather, it is just an analogy, which can only help to have clear-cut idea concerning this cutting-edge technology.
Salient Blockchain features
Blockchain stores blocks 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 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 mentioned earlier, Blockchain technology includes a very high application in the world of finance and banking. In line with the World Bank, more than US$ 430 billion money transfers were sent through it only in 2015. Thus, Blockchain developers have significant demand available in 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 is the most common GUI for the Blockchain technology. Users utilize the wallet to buy things they want using Bitcoin or any cryptocurrency.
