Web3 is a proposed next stage of the World Wide Web that is decentralized and uses blockchain technology rather than being controlled by a single entity. It aims to give users ownership and control over their data and digital identities. Some potential benefits include greater privacy, fewer middlemen, and built-in payment systems. However, current limitations include poor user experience, scalability issues, high costs, and lack of accessibility in mainstream browsers. While an ambitious vision, Web3 is still in early stages and some argue it may be an overengineered solution to problems that could be addressed through less complex means.

6. What’s Web3
Web3 = WEB protocols (HTTPs,TCP,FTP,ETC.) + Blockchain network
(Not only)

11. Web 3 TRIES to solves web issues similar to those solved by Bitcoin
What problem does web3 tackles?
● Centralisation
● Censorship
● Bypass middlemen (Direct and seamless
payment)
● Empower the end user

12. Middlemen are removed from the equation, blockchains like Ethereum provide a trust-less platform where the rules
are unbreakable and data is fully encrypted.
No central point of control
Because data will be decentralized and distributed, hackers would need to turn off the entire network, while state -
sponsored tools such as Vault7, used by the three-letter agencies, would be rendered obsolete
Dramatic reduction in hacks and data breaches
End users will regain complete control of data and have the security of encryption. Information can then be shared on a
case-by-case and permissioned basis
Ownership of data
Anti-monopoly Web

13. Benefits of Web3
With the third-generation web, you will have a single profile that
works well across different platforms. You will have ownership of
the personal profile and all associated data.
Easy Data Sharing
Web 3.0 can enable you to easily access information relating to
any topic and from anywhere. It ensures easy access to a wealth of
valuable information.
Better Access to Information
With Web 3.0, you no longer have to worry about your privacy. You
can rest assured of the security of your data on the internet.
Greater Privacy
One of the significant benefits of Web 3.0 is fewer middlemen.
Decentralization of the web allows the providers to directly
connect with the consumers.
Fewer Middlemen
Payments are built in via the native token e.g ether (ETH). No one can block you or deny you access to the service.

18. Web3 Limitations
UX – Interacting with web3 applications can require extra steps, software, and education. This can be a hurdle to adoption (Brave).
Scalability – Transactions are slower on web3 because they're decentralized. Changes to state, like a payment, need to be
processed by a miner and propagated throughout the network.
Cost – Most successful dapps put very small portions of their code on the blockchain as it's expensive
Accessibility – The lack of integration in modern web browsers makes web3 less accessible to most users.

20. The “Oracle Problem”
API providers become
oracles themselves and
deliver their data directly
on-chain.

decentralization

A decentralized Web 3.0 could encourage more
innovation in the virtual world, outside the
structure of the big tech firms.
