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 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.
Coming across this far was probably easy. But, one is yet to know what is Blockchain?
A 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 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 own benefits. It does not permit the database to be stored at any single location. The records in it possess genuine public attribute and can be verified very easily. As there’s no centralised version of the records, unauthorised users have no methods to manipulate with and corrupt the data. 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 make the concept or the technology clearer, this 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 process, one must wait till receiving the return copy to see the changes designed to the document. This is really because the sender is locked out from making corrections till the recipient is done with the editing and sends the document back. Contemporary databases don’t allow two owners access exactly the same record simultaneously. This is one way banks maintain balances of these clients or account-holders.
In contrast to the set practice, Google docs allow both parties to access exactly the same document simultaneously. Moreover, it also allows to see a single version of the document to both of these 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 a way, an extension of this concept. However, you should explain here that the Blockchain is not meant to share documents. Rather, it is just an analogy, which will help to have clear-cut idea about this cutting-edge technology.
More info of information across the network, which are identical. By virtue of the feature:
The data or information cannot be controlled by any single, particular entity.
There can’t be no failure point either.
The data 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 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 available in the market.
The Blockchain eliminates the payoff of the middlemen 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 type of desktops. Similarly, the wallet application may be the most common GUI for the Blockchain technology. Users make use of the wallet to buy things they need using Bitcoin or any other cryptocurrency.
