You are now learning about a new technology, but about a genius idea, and everyone interested in the Internet and information technology whose main concern is to know “What is the blockchain?”. And to put you in the picture dear and understand in an easy and simple way, let’s talk a little about the Internet first
The latest internet in the nineties of the last century is a huge technological and economic revolution, still in existence and in continuous expansion, as the Internet has affected all aspects of our lives, and it is difficult for us to even think about the possibility of living in a time and place where the Internet is not available, because it simply made life People are more accessible and more wealthy.
The Internet is a global network in which people exchange different information through different media and means. The Internet has undergone great development over the years, but despite this, information security, privacy and transparency remain among the most prominent problems associated with the use of the Internet.
The information is transmitted via the internet via transcription, meaning that the information is transmitted when it is created and sent to its destination by copying it several times! Example:
When you write an email, you have a copy of the message in the email message box, and when you send it to your friend, your message does not leave the message box, but rather remains in the “Messages sent” section, while the email message provider “for example Gmail or Yahoo” sends a copy to The messaging service provider for your friend and then the latter communicates your message in his e-mail box.
All of your emails are present on the servers of this service provider, and you may be denied access to them if your account is locked for some reason or the servers are down. So there is a central authority that controls you!
There is always multiple copies of any information which makes it difficult to exchange valuable things over the Internet because in every exchange, anything will be copied multiple times, which will lose its value.
That is why the blockchain technology came to solve these two problems in the internet through:
- Make the information available to you whenever and wherever you want.
- Ensuring that information is transferred from one person to another without the possibility of the first person retaining the same information.
- The strength of the blockchain technology lies in that it is the only technology so far that has made for the first time in history the possibility of a unique piece of information in several separate places.
