These days, technology is scaling newer heights of success at an unbelievably fast pace. Among the latest triumphs in this direction may be 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 several other things as well.
Coming across 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 some type of 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 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 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 e-mail, the conventional method 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 must wait till receiving the return copy to see the changes made to the document. This happens because the sender is locked from making corrections till the recipient is performed with the editing and sends the document back. Contemporary databases don’t 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 the 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 when the sharing involves multiple users. The Blockchain technology is, in a way, an extension of the concept. However, it is very important point out here that the Blockchain is not meant to share documents. Rather, it really is just an analogy, which will help to have clear-cut idea about this cutting-edge technology.
Bitcoin Revolution Site of information across the network, that 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 in 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 access computers in type of desktops. Similarly, the wallet application may be the most typical GUI for the Blockchain technology. Users make use of the wallet to buy things they need using Bitcoin or any cryptocurrency.
