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 brand new technology has greatly influenced the finance sector. In fact, it was 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, that is copied umpteen number of times across some type of computer network. Now, imagine the computer network is designed so smartly that it regularly updates the spreadsheet on its own. 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 in it possess genuine public attribute and may be verified very easily. As there’s no centralised version of the records, unauthorised users haven’t any means 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 across the virtual web.
To help make the concept or the technology clearer, this can be 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 need their sweet time to go through it, before they send back the revised copy. In this approach, one must wait till receiving the return copy to see the changes designed 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 don’t allow two owners access exactly 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 exactly the same document concurrently. Moreover, it also allows to view an individual 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 ways, an extension of the concept. However, it is very important point out here that the Blockchain is not designed to share documents. Rather, it really is just an analogy, which will help to have clear-cut idea concerning this cutting-edge technology.
Salient Blockchain features
Blockchain stores blocks of information over the network, that are identical. By virtue of this feature:
The data or information cannot be controlled by any single, particular entity.
There can’t be worldoftechnicalanalysis.com .
The info 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 world of finance and banking. In line with the World Bank, 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 User Interface), which facilitated the normal man to gain access to computers in type of desktops. Similarly, the wallet application is the most typical GUI for the Blockchain technology. Users utilize the wallet to buy things they need using Bitcoin or any cryptocurrency.
