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 new technology has greatly influenced the finance sector. Actually, it had been initially developed for Bitcoin – the digital currency. But now, it finds its application in several other things as well.
Sounding 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 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 inside it possess genuine public attribute and may be verified quickly. As there is 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 millions of computers, making the data easily accessible to almost anyone over the virtual web.
To 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 eMail, the conventional method of sharing documents is to send a Microsoft Word doc as attachment to a recipient or recipients. The recipients will need 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 start to see the changes made 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 as well. This is one way banks maintain balances of these clients or account-holders.
In contrast to the set practice, Google docs allow both the parties to access the same document as well. Moreover, it also allows to see an individual version of the document to both of them 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 ways, an extension of the concept. However, you should 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.
Salient Blockchain features
Blockchain stores blocks of information across the network, which are identical. By virtue of this 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 includes a very high application in the wonderful 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, coincapcentral have significant demand in the market.
The Blockchain eliminates the payoff of the middlemen in such monetary transactions. It was the invention of the GUI (Graphical User Interface), which facilitated the normal man to access computers in type of desktops. Similarly, the wallet application is the most typical GUI for the Blockchain technology. Users make use of the wallet to buy things they need using Bitcoin or any cryptocurrency.
