The main differences between Web 2.0 and Web 3.0 are that Web 2.0 uses unique web addresses and stores information in a fixed location while Web 3.0 stores information based on content. These two approaches are not in the interest of the Internet giants. They also differ in the degree of centralization and decentralization, with no network being completely independent.
AJAX
The first generation of the web was defined by Tim Berners-Lee in 1989 and focused on basic connectivity and hyperlinks. It evolved with the development of web browsers. The first modern browser was NCSA Mosaic, developed by Marc Andreessen and released in 1993. These browsers used a variety of new technologies to improve the user experience.
AJAX, also known as Asynchronous JavaScript, is a technology approach that allows websites to update and modify content on the fly. It was popularized by sites such as Google Maps, which used AJAX to zoom and scroll. Another defining feature of Web 2.0 is CSS, which allowed developers to create complex design layouts.
JavaScript
Web 2.0 introduced technologies such as AJAX, HTML5, CSS3, and JavaScript. These technologies allowed web designers and developers to create interactive, user-friendly websites. They also helped to build applications for websites. Web 3.0 brought more features and capabilities to the web, including AI and machine learning, as well as decentralized protocols and the semantic web.
JavaScript allows for a two-way flow of content between the site’s user and third-party applications. This enables users to create and share content with one another while facilitating interaction with other websites. It also offers APIs, which allow different applications to communicate and share data. Web 2.0 applications also tend to interact with the end-user.
A significant difference between web 2.0 and web 3.0 is the underlying technology. Web 2.0 introduced numerous innovative technologies such as AJAX, CSS3, and HTML5. However, web 3.0 focuses on new technologies, such as AI, the semantic web, and knowledge bases.
Permissionless systems
Web 3.0 has some fundamental differences from Web 2.0, most notably the fact that it doesn’t rely on “permission” and “trust.” With Web 3.0, end-users can publish their content wherever they choose. While this can have some drawbacks, it’s beneficial for the money-making sector of the internet. Furthermore, there is no central switch, which means no one can censor your content or your personal information.
Web 2.0 tended to rely on centralized resources, such as web servers. The user accesses a URL via HTTP, which translates to a particular server, which then draws content from a handful of similar systems. Web 3.0, on the other hand, makes use of the enormous power of the client system. Web applications are now available from many sources, including the cloud.
Dynamic content
Dynamic content is one of the defining features of the new Web. While Web 2.0 focuses on creating communities, Web 3.0 aims to give users more control over their digital lives. Web 3.0 allows people to create their own content and interact with it in various ways. It is also based on a read-write web standard, which makes it possible to incorporate rich media and share information with others.
The main difference between web 2.0 and web 3.0 is that Web 2.0 has interactive elements and allows users to react to content. This allows users to like, comment on, and follow content creators. These interactive features have resulted in full web apps, which provide functionality normally available only on desktop applications. Web 2.0 sites are powered by scripting languages that enable dynamic rewriting of information.
Node-to-node transactions
Web 3.0 will be a fundamental change in the way the Internet works. Instead of centralized platforms that are governed by the government, users will have direct access to data across applications. Web 3.0 will be based on decentralized consensus and will not require a central authority to approve transactions. In addition, the new system will allow users to interact with each other without having to be located in the same location.
While web 1.0 was built for information, web 2.0 is more social and interactive. Web 3.0 will allow users to create and publish content and collaborate with others on the same site. Both technologies will rely on HTML, which defines the layout of webpages and their delivery of them. While HTML will remain the foundation of web 3.0, it will connect to data sources differently than earlier generations of the web.
