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. But 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 inside it possess genuine public attribute and can be verified quickly. As there is no centralised version of the records, unauthorised users haven’t any means to manipulate with and corrupt the info. 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 help make the concept or the technology clearer, this can be a good idea to go over 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 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 start to see the changes made 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 do not allow two owners access the same record simultaneously. This is how 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 concurrently. 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 a way, an extension of this concept. However, it is very important point out here that the Blockchain isn’t designed to share documents. Rather, it is just an analogy, which will help to have clear-cut idea relating to this cutting-edge technology.
Bitcoin Era 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 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 includes a very high application in the wonderful world of finance and banking. According to the World Bank, 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 was the invention of the GUI (Graphical INTERFACE), which facilitated the normal man to access computers in form of desktops. Similarly, the wallet application may be the most typical GUI for the Blockchain technology. Users utilize the wallet to buy things they need using Bitcoin or any cryptocurrency.
