These days, technology is scaling newer heights of success at an unbelievably fast pace. Among 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 was initially developed for Bitcoin – the digital currency. However now, Bitcoin Revolution 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, that is copied umpteen amount of times across some type of 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’s no centralised version of the records, unauthorised users haven’t any methods 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 just a good idea to discuss the Google Docs analogy.
Google Docs analogy for Blockchain
After the advent of the eMail, 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 needs to wait till receiving the return copy to see the changes designed to the document. This happens because the sender is locked out 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 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 parties to access 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 when the sharing involves multiple users. The Blockchain technology is, in ways, an extension of the 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.
Salient Blockchain features
Blockchain stores blocks 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 single 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 stated earlier, Blockchain technology has a very high application in the wonderful world of finance and banking. Based on 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 such monetary transactions. It had been the invention of the GUI (Graphical INTERFACE), which facilitated the normal man to gain access to computers in form of desktops. Similarly, the wallet application is the most common GUI for the Blockchain technology. Users make use of the wallet to buy things they want using Bitcoin or any cryptocurrency.
