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. But now, it finds its application in a number of other things as well.
Coming across this far was probably easy. But, Bitcoin Revolution Official is yet to know 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 summary of the Blockchain. Blockchain holds information as a shared database. Moreover, this database gets reconciled continuously.
This approach has its 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 quickly. As there’s no centralised version of the records, unauthorised users have no means to manipulate with and corrupt the info. The Blockchain distributed database is simultaneously hosted by millions of computers, making the data easily accessible to almost anyone across the virtual web.
To make the concept or the technology clearer, it is just 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 would be to send a Microsoft Word doc as attachment to a recipient or recipients. The recipients will take their sweet time to go 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 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 do not allow two owners access the same record as well. 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 view an individual 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, it is important to 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, 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 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. 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 common man to access computers in form 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 cryptocurrency.
