hello everyone! In this video, I would like to talk about "web 3.0". I have noticed that
the term "web 3.0" or simply "web3" was trending on twitter many times
for the past few few weeks, actually the term is becoming a buzzword in these
days, currently there is no clear-cut definition for the word web3.0 okay
but we can just simply understand it as the next version of the web 2.0 which currently
we are experiencing in the internet okay so currently we have social media sites and
blogs and other things right so these are 2.0 okay actually in 1991 the internet started
its journey. The time period from this 1991 till 2004 is known as web 1.0 okay so basically in
those days the websites mostly will be like static webpages okay so only a few companies and the big
corporations will be hosting the content and the users are not having any other option just
they have to read it, if they find any mistakes they don't have any control to correct it. If there
are any fake news or any incorrect information in the news item or any other content there is no
option to correct it okay and they don't have any option to convey their opinion whether this
article is good or not like that. From the year 2004 that web 2.0 era started, till this time
it's continuing okay so we started seeing the social media websites like facebook twitter
youtube and other blogs okay so now uh people are people can uh add their own content okay
and if if you're reading a news item in any big news company website
and if you find any mistake or wrong information in that content you will
be able to inform it through the comments, even if the company is not having time to correct
their mistake people who are reading the content will be reading your comments also, so basically
they can get some more correct information. This is known as web 2.0 so the people are having the
option or feature to give their opinion and you can add your own blog post you can run your
own youtube channel so people can express their opinions and thoughts and their feedback
so this system is known as web 2.0, so obviously it is giving more power to the users, but still
it's having a lot of problems say for example currently i'm running this youtube channel right
so i have the freedom to express my opinions and any content through this channel
but still it is fully controlled by google right the company google can remove my content if they
decide to do so, and governments and legal entities are having the power to remove my content or
just hide my content, say for example the same youtube video
will be visible in one country and it will be blocked in other country with a court order from
that particular country okay so though the 2.0 is having or giving more power to the users
still it is having its own shortcomings, so basically it is controlled by few people like the
company which is hosting the content and the governments and other legal entities
are having more control apart from that the internet service providers can also
block the content if they decide to do so okay the major problem with web 2.0 is the privacy problems
and the data privacy, say for example, the companies like facebook, twitter, youtube, these
social media companies are hosting the content as well as the data private privacy data of the users
they are keeping the private data of the users and the creators okay uh they have the access to
that content so uh obviously they can misuse it okay even only one employee of the company can
decide to misuse it right, or hackers can take the content that privacy private content and
they can (mis)use it, it will affect all the users right so it is the current scenario of web
2.0 it is giving some power to the users but it's having its own shortcomings like
controlled by few entities and it's prone to hacking other issues
and it is still censored by the hosting company and governments right. To handle this problem
that new web web 3.0 is coming okay uh it is based on the blockchain technology okay
so it's basically a decentralized platform so we need not depend on one particular
company to store the content okay so it will be a decentralized thing so that problem is obviously
solved and any particular government is not having any authorization over it and uh since uh it's
taken care by the decentralized systems like blockchain there is no almost there is no uh
probability of uh shutdown or any uh downtime for the content okay uh we used to see that the down
of twitter and uh facebook uh even youtube right so it may not happen if everything is
decentralized okay so basically web 3.0 is giving more power it is allowing us to keep the content
always and it is not having any censorship problem and
actually it is not controlled by any person and there is no privacy problem and hacking
problems like these are the advantages but some people are criticizing that 3.0 by stating that
it will create problems like hate-speech and other
problems okay but we don't know how it's evolving we have to wait for it okay but almost
it is looking good and many small companies started implementing it we can see a lot of
web 3.0 apps and one more thing is we shouldn't confuse the term web 3.0
with the semantic web actually the world wide web creator tim berners-lee mentioned his concept
of semantic web with the term web 3.0 actually previously uh before uh two years back it was
like the term "web 3.0" was mentioning or indicating the semantic web only
but these days the meaning or the context of the term web 3.0 was completely changed so these
days uh it is indicating the blockchain based technology okay so we shouldn't uh
confuse the terms okay and definitions so actually i'm not much familiar with blockchain technology
but in this year i'm planning to go through the blockchain developments so mostly uh i
will be uploading more blockchain related news in this channel and if i have enough time i'll be
trying to learn it and develop some apps okay if you know any other good place to start learning
blockchain just let me know through the comments thanks for watching this video
