What is Web 3.0 and its features - Pros and Cons
What is Web 3.0 and its features?
Before discussing web 3.0 first we discuss the history of Web 1.0 and Web 2.0 and also talk
about why there is a need for web 3.0 and also the pros and cons of Web 3.0.
History
What is Web 1.0
It was designed in 1989 by Tim Berners-Lee.
In that era, the Internet was treated like a newspaper meant people read the content and that’s it.
There was no interaction between the user (content reader) and the sites. They only read information
present on sites operated by web browsers, URLs, HTML etc. It lasted till 2005.
What is Web 2.0
It was first designed by Darcy DiNucci and then became popular in 2004 by Tim O’Reilly and Dougherty at a conference. It is the web which we are using now in the present era. In this era, users can not only read but also can Interact with others.
For example, on YouTube (you can comment), you can create your content. On Facebook, you can
also, interact.

Why there is a need for Web 3.0?
The first question that comes to mind is what are the cons of Web 2.0 that we need for web 3.0.
The first problem is that only one or two major companies are those that are ruling over the
Internet. Google controls over 87% of research. Facebook which is currently Meta reaches over 3.6
billion people each month.
The problem is who has given them authority to rule. The data that we give them is used as ads.
These ads some times convenient but privacy is very important. So now the time has come that users
to take control of the web and exactly in simple words it is Web 3.0.
What is Web 3.0?
It is introduced by Gavin Wood who is the Polkadot founder and co-founder of Ethereum.
You will understand Web 3.0 by following characteristics or key aspects.
- Decentralization
- Open source
- Blockchain
Decentralization
In simple words, decentralization means scattered, divided, spread etc. The data or power is
centralized in major companies like Facebook. They have control over it. In Web 3.0, it will be
decentralized means distributing it to all not only a specific one.
Open source
Open source means anyone can modify it according to their preferences. There will be no restrictions
over it. To understand it, let’s take an example of android. Anyone can modify it according to their taste. Like this in Web 3.0, anyone comes and modified it according to their priorities.
Blockchain
Blockchain is a very secure and strong technology in which data is stored. As the name suggests, data
is stored in blocks and these blocks are in the form of chains. This technology keeps data safely. So
here this privacy factor will be strengthened.
These are the factors which we have discussed presently.
Now we Talk about the Pros and cons of Web 3.0.

Pros of Web 3.0
The major 5 pros of 3.0 are given below:
Anonymous Single Sign On
When the user uses the interest or visits any website they have to fill in the information
(means our data e.g email, name etc) every time. Whenever they visit any website they have to make
a new account. So, here Web 3.0 provides the facility of an anonymous single sign which means users
have to create an account only one time and they can access any of the websites with the same
account. Due to this, it will provide security.
Self govern
Self govern means own rules or decisions. In Web 3.0, website users can create their
decision or rules. Let’s take an example of Facebook creating rules for its users but Web 3.0 reverse
them. In Web 3.0 we make rules.
Better search
In this era, we remain particular about our research. We write or speak (on Alexa, Siri ) we
use proper sentences for our research and it is a kind of inconvenient thing also. To make it normal,
web 3.0 gives the feature that we normally ask anything in our simple words. Some believe that
Metaverse can implement it. But let’s see what happens.
Personalized browsing experience
A personalized browsing experience means that ads or website changes according to users’
taste or preference. With-it users can experience their personalized preferences on that what they
want to see or what they do not. They will experience their own personalized (customized) browsing.
Uninterrupted services:
Any website is down easily, it stops working. For example, when WhatsApp was a breakdown at
that time was very inconvenient for users. Due to that type of problem, Web 3.0 provides
uninterrupted services. As discussed earlier in features of Web 3.0 that in it data is stored in
blockchains which are decentralized or in simple words distributed.
Cons of Web 3.0
There are some cons of Web 3.0 also. These are:
Ownership concerns
As discussed earlier that Web 3.0 is decentralized so that will be no specific owner. But
According to Jack Dorsey(ex SEO Twitter), there should be one giant power. The data should not be
decentralized.
If the data is decentralized there may be some problems in future like regulation issues and
Cyber crimes may also be increased.
Old hardware will be obsolete
Old hardware will be useless. Because 3.0 is very feature-loaded so it demands so many
resources so it urges to update. If we update it, old hardware will be useless.
Easier access to personal and public data
If the data is distributed then it is much more accessible to others and so maybe anyone can
see it easily it is said that blockchain is very secure but we have always noticed that tech is hackable.
Conclusion
Web 3.0 is theory. It is not implemented now. It has many supporters as well as there are many
arguments on it.
