Web 3.0 ,
also known as the Semantic Web or the Decentralized Web, is the next evolution of the internet. It’s a vision of the future of the web where machines are able to interpret and understand the meaning of data, making it more intelligent, connected, and decentralized.

The first generation of the internet,
Web 1.0, was mostly a static, read-only web, where information was accessed through web pages that were created by a small group of people. The second generation, Web 2.0, was focused on user-generated content, social networking, and e-commerce, enabling users to contribute, interact, and transact with one another.
However, with the rise of Big Data, AI, and the Internet of Things, the need for a more intelligent, interconnected, and decentralized web has become apparent. Web 3.0 aims to address these challenges by leveraging new technologies such as distributed ledgers, smart contracts, and decentralized storage.
At its core, Web 3.0 is about creating a more decentralized and distributed internet, where users have greater control over their data and online identity. One of the key features of Web 3.0 is the ability to use blockchain technology to create decentralized applications (dApps) that run on a peer-to-peer network, making them more secure and less reliant on centralized servers.
Another important aspect of Web 3.0 is the use of semantic data, which enables machines to understand the meaning of data and relationships between different types of data. This is achieved through the use of standardized metadata and ontologies, which help to create a more interconnected and intelligent web.
Web 3.0 also enables a more personalized and contextualized web experience, where data is more accessible, trustworthy, and secure. This is achieved through the use of digital identity systems, which enable users to control their online identity and manage their digital assets more securely and transparently.
In addition, Web 3.0 aims to enable more seamless and frictionless transactions between different parties, without the need for intermediaries such as banks or other third-party providers. This is made possible through the use of smart contracts, which are self-executing contracts that can automate the process of verifying, enforcing, and executing agreements.
Overall, Web 3.0 represents a major shift in the way we think about the internet, and how it can be used to connect people, data, and machines in new and innovative ways. As the world becomes increasingly digital, the need for a more decentralized and secure web has never been more pressing, and Web 3.0 is poised to play a key role in shaping the future of the internet.
Some visions are based around the concept of decentralized autonomous organizations (DAOs).[Decentralized finance (DeFi) is another key concept; in it, users exchange currency without bank or government involvement.Self-sovereign identity allows users to identify themselves without relying on an authentication system such as OAuth, in which a trusted party has to be reached in order to assess identity. Technology scholars have argued that Web3 would likely run in tandem with Web 2.0 sites, with Web 2.0 sites likely adopting Web3 technologies in order to keep their services relevant
Kevin Werbach, author of The Blockchain and the New Architecture of Trust, has said that “many so-called ‘Web 3.0’ solutions are not as decentralized as they seem, while others have yet to show they are scalable, secure and accessible enough for the mass market”, adding that this “may change, but it’s not a given that all these limitations will be overcome
