Transcripts

ray is a tech savvy guy and loves to

spend most of his time exploring the web

on his laptop

one fine day he was going through an

article on futuristic gadgets and

suddenly he noticed an ad for the ps5

popping right beside the article

he found it a little strange as he

recalled searching for that just a few

hours ago

later that day he came across some

suggestive ads popping up related to

buying future leading gadgets

and that is when he freaked out thinking

how can it be possible that what he was

searching for just a few hours or days

ago on the internet is now suggesting

ads related similar to them

so he thought of going to his elder

brother aaron who is a software engineer

in an mnc

upon understanding the situation

he explained to ray that all of this is

happening because we are in an era of

web 2.0

it all started in 1994 when web 1.0 was

introduced to the internet

basically web 1.0 was all read only

content that was not interactable and

was similar to a huge wikipedia page

but after a few years in 2004 web 2.0

came into the picture

web 2.0 made the internet much more

interactive because of developments in

web technologies such as javascript

html5 css3 and others which allowed

companies to create interactive web

platforms like youtube facebook

wikipedia and many more

he further added that when we seek out

information or data of any kind from any

web platforms present on the internet

simultaneously unknowingly we also

provide them with information related to

our choices and interests which are

stored in cookies which later they sell

to various companies who make use of

this data to advertise exactly what you

were looking for

and this is how ray was able to see ads

of his concerned interests

ray was fascinated by how the internet

has evolved and how it works amazingly

but at the same time he was concerned

about the lack of privacy offered by it

ray out of his concern asked aaron is

there any way that one can get rid of

the loopholes of the current web 2.0

when aaron answered yes there are a lot

of ways to do that using tor browser

incognito mode etc

but these are not permanent solutions

and there can be fluctuations in their

reliability

but this scenario can be changed not

just for you but for everyone using the

internet with the help of web 3.0

ray was curious about it and asked what

is web 3.0

erin explained that web 3.0 is the next

step in the evolution of the internet

allowing it to process data with near

human intelligence through the use of

artificial intelligence and blockchain

technologies

that run innovative programs to help

users by providing them with their

relevant choices

it's a significant step toward open

trusting and permissionless networks

aaron further added to fully comprehend

this we must first explore the four key

features of web 3.0 first is

decentralization

blockchain will help to centralize data

storage while also establishing trust in

the virtual world

because web 3.0 allows information to be

retrieved based on its content

it can be kept in several locations

simultaneously

making it decentralized this would

dismantle the vast databases currently

maintained by internet giants like

facebook now meta and google giving more

power over people

second is trustful and permissionless

web 3.0 will also be trustful and

permissionless which means that

participants will be able to interact

directly without the need for a trusted

intermediary or permission from a

governing body due to this you can

access any data relevant to your choice

without any permission from any other

node or third party for example

if you are researching for some data you

don't need to accept its cookies or you

don't need to provide any sort of

details as there is a trustful bond

between you and the web

third is artificial intelligence and

machine learning

in web 3.0 through technology based on

semantic web ideas and natural language

processing

computers will be able to understand the

information in the same way that people

do

for example i love paris and i heart

paris may seem different in syntax

however their semantics are nearly

identical this will help the user to

achieve more relevant content to their

choices and will provide them ease with

internet browsing

fourth is connectivity and ubiquity

in web 3.0 the internet will be

accessible to everyone anywhere at any

time

because iot internet of things

technology will launch in several new

smart devices

these internet connected devices will no

longer be limited to pcs and smartphones

as they were in web 2.0 understanding

the shortcomings of web 2.0 corporates

like amazon apple and google are

transforming their existing services

into internet 3.0 apps that abide by

these four principles

siri and wolfram alpha are two

applications that use web 3.0 features

after learning about this ray was

relieved by the fact that web 3.0 is

going to bring so much of a difference

not just in his life but also to the

society as a whole

so here's a question for you

how is web 3.0 related to blockchain

a

it helps create smart contracts for web

pages on the internet

b

it helps web 3.0 storage data in the

blockchain

c

it offers a decentralized experience to

its users

d

all of the above

please take a minute to think about it

and leave your answers in the comments

section below three lucky winners will

receive amazon gift vouchers

web 3.0 will offer a more personalized

and customized surfing experience and a

smarter and more human-like search

assistant and other decentralized

benefits

all of which are believed to contribute

to a more fair web

this will be accomplished by giving each

user control over their data resulting

in a richer overall experience

in a nutshell the internet will become

considerably more intertwined in our

daily lives when web 3.0 arrives
