Web 3.0 is the next step in the evolution of the internet. Well then, it is important to understand the history of the internet. Or, what are Web 1.0 and Web 2.0.

When the internet arrived in 1994 the webpages were static in nature. This means that you can only read the contents of the webpage and the pages linked to that page, kind of like Wikipedia. You can’t interact with this page, cannot signup, or even heart a photo that you like. This was called Web 1.0

Then came web 2.0. Thanks to technologies like HTML, CSS, and JavaScript we are now able to interact with the web pages using our computer. Most of the web apps (like YouTube, Facebook, Google, etc.)we use currently are based on the idea of Web 2.0.

This also means that we can receive data from a server and even give data about our usage back to it with or without our proper knowledge.

Have you ever searched for a Apple MacBook pro in google and then after a couple of hours or days all sorts of ads about the laptop start popping up on the web pages that you browse.

That is the servers of Google or Facebook giving you personalized ads by using the data that you give them based on your browsing. As I said you may not be aware of them taking your data. This data is stored in the serves of these internet companies and can even be sold to advertisers.

Now, it is a lot of fun to browse the internet but what about your privacy? How secure is your data within these centralized servers? Is there a way to make this process more trustworthy and restore privacy?

Yes, That is where Web 3.0 comes in to picture.

In web 2.0 we have no control over our data. The centralized companies own this data and use them. But in Web 3.0 we own our data.

Web 3.0 utilizes blockchain technology and the tools of decentralization. You can click here to know more about blockchain, but in simple terms, it is a system of recording information so that it is unable to difficult or impossible to cheat the system.

Your data (including the videos you post or what you write) is not owned by companies with centralized servers. Instead, it would be inside thousands of computers around the globe ensuring the blockchain network is not hacked or censored.
