Web3 is the third generation of the internet currently being built, where websites and apps will be able to process information in a smart human-like way through technologies like artificial intelligence (AI), machine learning (ML), Big Data, decentralized ledger technology (DLT), and more. At present, Web3 is still a rather undefined concept that could take 5-10 years to build if we look at the transition from Web2 to Web3. In fact, we might very well first see a prolonged era of Web2.5, where Web2 platforms gradually onboard useful Web3 protocols.

2. What Is Web 3.0?
■ Web 3.0 is the upcoming third
generation of the internet.
■ Websites and apps will be able to
process information in a smart
human-like way.
■ Technologies like machine learning
(ML), Big Data, and blockchain.
■ Originally called the Semantic Web
by World Wide Web inventor Tim
Berners-Lee, and was aimed at
being a more autonomous,
intelligent, and open internet.
■ In order to understand the
evolution correctly, we must check
the history of internet.

3. WEB 1.0 (1989-2005)
■ Web 1.0, also called the Static Web &
read-only web.
■ Only offering access to limited
information with no user interaction.
■ One-sided information, consumers
could just consume.
■ Decentralized: Powered by regular
computers from regular users.
■ Open-source: Anyone could build on the
Web.
■ Read-only: Publishing content required
some technical skills, so most users
were readers.

4. WEB 2.0 (2005-present)
■ Advancements in web technologies like
JavaScript, HTML5, CSS, enabled
startups to build interactive web
platforms such as YouTube, Facebook,
Wikipedia and many more.
■ This led to that the data of users are
beingstored and controlled by limited
number of tech giants such as
Facebook, Google, Amazon, Twitter, and
a lot more.
■ As a result of that, these companies
started to use the data of users to make
targeted advertisements, violating the
users’ privacy.
■ Also this led to that these companies
control what content being posted on
the internet and they can delete or allow
whatever they want.

5. HOW WILL WEB 3.0 WORK?
■ Web 3.0 utilizes blockchain technology to
create true decentralization.
■ Because of its key decentralization feature,
Web 3.0 lends itself to technologies such as
blockchain, distributed ledger,
and decentralized finance (DeFi).
■ They will be interoperable, seamlessly
integrated, automated through smart
contracts.
■ Devices will be connected in a decentralized
network rather than relying on server-based
databases.
■ We won’t need to keep all our data on
centralized servers, rather we will own it
ourselves independently, choose what we
do with it.

6. HOW WILL WEB 3.0 WORK?
■ Web 3.0 tokens are essential to a
decentralized internet. This is because
interacting with the blockchain costs
gas fees.
■ This will be necessary to replace
exploitative advertising and other
direct targeting from third parties that
use your data against you. To cover the
small fees, you could choose to sell
your data to marketers. You will still
own your data, but you will be able to
give access to certain things that
marketers can then use to create
targeted advertising campaigns.
■ So, what is a token??

7. WHAT ARE TOKENS?
■ A token is a digital asset such as
cryptocurrencies.
■ Tokens are two types:
1. Fungible.
2. Non-Fungible Tokens (NFT).
■ Fungible Tokens: such as Ether, the
cryptocurrency of Ethereum network. It’s
a digigtal asset that you can trade with
other people. This token is fungible as it
is equal to other tokens in volume and in
value like a coin is always worth the
same value as another coin.

8. WHAT ARE TOKENS?
■ Non-Fungible Tokens (NFT):
It represents assets that aren’t exactly
alike such as baseball cards, digital
art work, or real state.
Each token is unique and represents a
different item.
This means that its actual market
value might be different when you go
to trade it in for some other kind of
tokens.

9. Features of WEB 3.0
■ To really understand the next stage of the
internet, we need to take a look at the four key
features of Web 3.0:
■ Ubiquity: We can access the same information
and data from multiple applications without
the need for one specific device.
■ More Privacy: Web 3.0 will focus on privacy
and security instead of control and
surveillance. It will empower you to choose
which data you’d like to share and which
you’d like to keep to yourself. Personal data
will be owned by you and nobody else.
■ More Security: Web 3.0 will be more secure
than previous iterations of the internet. This
will be made possible through blockchain
technology and its decentralized nature.

10. Features of WEB 3.0
■ Data ownership: Trust will be more natural in
web 3.0. You won’t need to give your data
away to big corporations at every turn.
Instead, you will own it for yourself.
■ Decentralization: Web 3.0 will not incentivize
centralized networks. This is key to a fair and
trustless democracy of any kind. It will be
transparent.
■ Interoperability: Developers will find it
increasingly easy to build new dApps, which
will work on all smart devices
■ No Interruptions: Distributed systems are less
likely to face service outages because there is
no central authority, so no single point of
failure.

11. Features of WEB 3.0
■ Semantic Web: The semantic web enables data to
be shared across a multitude of platforms,
systems and communities. It will act as a bridge
for different data formats, leading to enhanced
connection.
■ Permissionless Blockchains: Anyone can join and
contribute. All users can access services because
code does not discriminate.
■ Spatial Web and 3D Graphics: Some futurists also
call Web 3.0 the Spatial Web as it aims to blur the
line between the physical and the digital by
revolutionizing graphics technology, bringing into
clear focus three-dimensional (3D) virtual worlds.

12. DAPPS
■ A dApp is a decentralized application. There
are lots of different types of dApps, just as
there are lots of different apps.
■ In essence, web 3.0 will decentralize every
single facet of the current world wide
web. Here you can see how web 3.0
applications will work and how they will
differ from the apps that most internet users
interact with today.
■ Some of the companies that are building or
have products that they are transforming
into Internet 3.0 applications are Amazon,
Apple and Google. Two examples of
applications that utilize Web 3.0
technologies are Siri and Wolfram Alpha.

13. WEB 3.0 Frontend
■ It’s not much different from the normal
frontend.
■ You will still use Js or your favourite other
frameworks such as react or node.
■ The only different aspect is user
authentication.
■ As there are no centeralized databases, the
user authentication is a bit different in web
3.0.
■ The end-user uses a plugin like meta mask
to make their public wallet details available
to a decenteralized application.
■ There are libraries out there to make this
job easier such as: web3.js and ethers.js

14. WEB 3.0 Backend
■ It’s a lot different than our normal backend
code as web developers.
■ Instead of a server and database like PHP
and mysql, you’ll be writing smart
contracts.
■ There are frameworks there designed to
streamline development such as: Hard Hat
& Truffle.
■ These frameworks allows you to write
smart contracts in a language called
solidity.
■ It’s an object oriented language designed
specifically for writing smart contracts on
the blockchain.

15. Smart Contracts
■ Smart contracts contain your backend
code usually written in the solidity
language which is just an application
that lives on the blockchain that can
govern the behavior between multiple
accounts.
■ Smart contracts enable business
parties to manage, access and govern
asset tokens for any type of business
object on a transparent and immutable
digital ledger that is distributed to all
parties and requires consensus for
updates.
■ A smart contract is not “smart” in the
true sense of the word, it is rather only
as clever as its creators.

16. The Bottom Line
■ To use an analogy from the movies, if
Web 1.0 represented the black-and-white
movie era, Web 2.0 would be the age of
color/basic 3D, while Web 3.0 would be
immersive experiences in the metaverse.
■ Just as the 2010s was the decade when
Web 2.0 became the dominant force in
the global business and cultural
landscape, it might be Web 3.0’s turn in
the 2020s.
