These days, technology is scaling newer heights of success at an unbelievably fast pace. One of 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 was initially developed for Bitcoin – the digital currency. However now, it finds its application in a number of 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 amount of times across a computer network. Now, imagine the computer network was created 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 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 have no means 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 e-mail, the conventional method of sharing documents is to send a Microsoft Word doc as attachment to a recipient or recipients. Bitcoin Revolution Review will need 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 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 do not allow two owners access the same record as well. This is how banks maintain balances of these clients or account-holders.
As opposed to the set practice, Google docs allow both the parties to access the same document concurrently. 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 a way, an extension of this 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 concerning this cutting-edge technology.
Salient Blockchain features
Blockchain stores blocks of information over the network, which are identical. By virtue of the feature:
The data or information can’t be controlled by any single, particular entity.
There can’t be no failure point either.
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 stated earlier, Blockchain technology has a very high application in the 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 such monetary transactions. It had been the invention of the GUI (Graphical INTERFACE), which facilitated the normal man to access computers in type of desktops. Similarly, the wallet application may be the most common GUI for the Blockchain technology. Users utilize the wallet to buy things they need using Bitcoin or any other cryptocurrency.
