Web-3 an Introduction

[WEB-1]

was the place where you could only read things. So let's say you want some information , what you could do is make a simple google search and get it. You want to read the wikipedia , just go ahead and read it , but what you cannot do is write on it.

Or rather you cannot write on the internet itself. The best "writing" that you were able to do on web-1 was sending an email , through some forms. That's it. There was minimal interaction and very very boring.

[WEB-2]

Then came web-2 , now you had facebook and instagram and all sort of cool apps. Now you cannot only read data , but also write data on internet. This was revolutionary because now you can connect with actual people out there. People could talk to you , directly . And mails were not the only medium to convey messages via internet. Interactivity increased , we got games , video calls . We can write and read data , but we donot own the data.

That means , that all data is centralized , and thus authority over that data is centralized. For eg. let's say i want to post some content on this very specific platform and get paid for it. But this platform only pays me 45% of the sum that is earned from that piece of the content , now there's no way for me to increase that percentage.

[WEB-3]

[WEB-3] that is where decentralization comes into play. When you write , or upload the data . It does not reach any centralized server. It gets into the blockchain , the chain you are free to choose and it is basically stored in a network of computers. And through NFTs (Non fungible tokens) and cryptocurrencies , you can actually own it as well.

But of course owning something always comes with a cost , so either you pay per transaction or you pay through rent. The choice is yours. It gives you ownership on your own data , and the block is then sent onto the blockchain forever. Some of the famous chains are Solana , Ethereum and the one where it all started from - Bitcoin.
