==Web 2.0==

Web 2.0, coined/popularized by Tim O’Reilly between 1999 and 2004, describes the move from static desktop web pages designed for information consumption to interactive experiences and user-generated content due to mobile, social, and cloud innovations.<ref>[https://medium.com/fabric-ventures/what-is-web-3-0-why-it-matters-934eb07f3d2b What is Web3 and Why Does It Matter, Max Mersch and Richard Muirhead, Fabric Ventures, Medium]</ref> The concept encapsulates the current worldwide interoperability of the participative social web. The height of Web 2 ran roughly from 2005 to 2020. It works via siloed, centralized services run by corporations, such as [[ICANN]], and most of the value goes to Google, Apple, Amazon, and Facebook.<ref>[https://future.a16z.com/why-web3-matters/ Why Web3 Matters, Future, a16z]</ref> Web 2.0 is not technologically different from Web 1.0; it is an enhanced version. Web 2.0 refers to the 21st-century Internet applications that transformed the digital era following the dot-com bubble. Its web browser technologies include AJAX and JavaScript frameworks. It permits the collective retrieval and classification of information and dynamic, user-responsive content which flows between the site owner and site users often through evaluation and online commenting. Web 2.0 is characterized by many online tools, platforms, and applications that encourage end-user interaction, such as podcasting, blogging, tagging, RSS curating, social bookmarking, networking, media, and content voting.<ref>[https://www.investopedia.com/terms/w/web-20.asp Web 2.0, Investopedia]</ref>

==Web 3.0==

Web 3.0 began in 2021 and refers to the novel development of the backend of the web, as opposed to Web 2.0, which focuses on the frontend. The web3 era combines the decentralized, community-governed ethos of web 1.0 with the modern functionality of web 2. Web 3 is the internet owned by the builders and users and orchestrated with tokens.<ref>[https://twitter.com/packyM Packy McCormick]</ref> Data may not be owned but shared. Web 3 has been called the "[[Semantic Technology|Semantic]] Web," because it necessitates the use of a declarative ontological language to produce domain-specific ontologies that machines can use to reason about information and make new conclusions, not simply match keywords.<ref>[https://www.geeksforgeeks.org/web-1-0-web-2-0-and-web-3-0-with-their-difference/ The differences in Web 1, 2, and 3, Geeks for Geeks]</ref> In Web 3.0, computers should be able to distinguish information to provide faster, more relevant results. The 3D design is also part of 3.0 websites and services. Information will be more connected due to semantic metadata, the content will be accessible by multiple applications, and with [[IoT]], every device can become connected to the web. Web3 research focuses on provable security, cryptography, and privacy; consensus and optimization of decentralized algorithms; crypto-economics and game theory; networking; and behavioral economics.<ref>[https://research.web3.foundation/en/latest/ Research, Web3 Foundation]</ref>
