Web 1.0 VS Web 2.0 VS Web 3.0

Introduction

If we don't know about decentralised internet by the end of this decade, we have to struggle like some old or illiterate people struggling now to use internet.
Web 3 is the decentralised internet.
Before knowing web 3, we first need to know about web 1 and web 2.

This article is an attempt to give readers a sense of what web 3 is.

Web 1.0 is the first iteration of web.
The users could only see or read the data from the web applications.
It wasn't possible to send data from user side to the server.
The creators were mostly developers who build websites.
The websites used to be static and hence, no interactivity.
In simple words, websites were just newspapers but on computer screen in web 1.0 era.

The web that most of us using extensively now-a-days is web 2.0 .
In web 1.0, you need to be a developer to share data through internet as you have to code the web application by yourself.
But in web 2.0, you are not coding anything to share data on internet.
We are just using an application like facebook or whatsapp to share anything.
Web 2.0 is web 1.0 with interactivity.
Users can not only read the data but can also write data (send data to server).

In web 2.0, the companies which built the applications for people to use has the centralised authority.
That is why this is centralised internet.
Companies have the access to the user data with which they can do whatever they want like advertising, recommendations.
They are charging users for letting the people use their application like buying apps on app store or play store.
Banks are also centralised and governments can also intervene in their decisions.
These centralised organisations can shut down whenever they want.

All these are because of having a centralised power. In decentralised system, everyone in the network has equal power.

Web 3.0 aims to solve the issues discussed above.
Web 3.0 applications doesn't just run on a single server and use a single database.
Instead, they run on a block chain.
To know what is block chain and how it works, read this short and informative article written by me a short article on block chain
Applications which run on block chain are called decentralised applications (Dapps).
Our data is safe in web 3.0. It is because that our identity in web 3.0 is a wallet address which is a long hash value rather than our actual details like name etc.
Web 3.0 uses a peer to peer architecture.

There are many other advantages and details regarding to web 3. But this article aims to differentiate web 3 from web 2.
