What is web 3.0(web3)?
Web 3.0 signifies the forthcoming stage in the evolution of the World Wide Web, serving as the user interface for accessing internet documents, applications, and multimedia.
Currently in the developmental phase, Web 3.0 lacks a universally agreed-upon definition. Even its proper spelling remains a topic of debate, with analyst firms such as Forrester, Gartner, and IDC toggling between "Web3" and "Web 3.0."
However, it is evident that Web 3.0 will prioritize decentralized applications and likely incorporate extensive use of blockchain-based technologies. Additionally, it will harness the power of machine learning and artificial intelligence to create a more intelligent and adaptable web.
Evolution of the web
If Web 3.0 becomes a reality, it will mark the next phase after two previous iterations of the web.
The initial generation, known as Web 1.0, originated in 1989 through the efforts of Tim Berners-Lee, a British computer scientist. He applied hypertext concepts proposed by American information technology pioneer Ted Nelson in 1963, creating the Hypertext Markup Language (HTML) and the Hypertext Transfer Protocol (HTTP). These technologies governed how content was displayed on browsers and how web servers transmitted files to browsers. Berners-Lee also envisioned a "Semantic Web," aiming to interlink data across web pages, although hardware limitations hindered its implementation.
The public's awareness of the web grew in 1993 with the introduction of Mosaic, the first widely used browser, later renamed Netscape Navigator. User-friendly graphical browsers like Microsoft Internet Explorer and, later, Apple Safari emerged. Popular search engines such as Yahoo! Search, Lycos, and AltaVista appeared, but by 2004, Google had surpassed many of its competitors.
Around the millennium shift, experts advocated for a more interactive web, labeling it Web 2.0 and distinguishing it from the basic connectivity and static websites of Web 1.0. Tim Berners-Lee elaborated on his Semantic Web concept in collaboration with an article in Scientific American. Publisher Tim O'Reilly played a role in promoting Web 2.0 by organizing a dedicated conference. The dream of an interactive web materialized with the rise of social networks like Facebook. During this period, the World Wide Web Consortium, the web's standards body, introduced a Semantic Web standard. Coinciding with these developments, two pivotal Web 3.0 technologies emerged: cryptocurrency and blockchain. Influential figures in journalism and technology, such as Gavin Wood, Ethereum's co-founder, began popularizing the terms Web 3.0 and Web 3 to signify a decentralized, semantically aware version of the web.
Why is Web 3.0 important?
If the decentralization of the web's architecture delivers even a fraction of the benefits promised by Web 3.0 proponents, it has the potential to fundamentally transform how people interact online and how companies generate revenue from their products and services.
Web 2.0 giants such as Amazon, Google, and Meta, the parent company of Facebook, experienced rapid growth by accumulating vast amounts of customer data and monetizing it through various means. However, Web 3.0's global peer-to-peer network could disrupt this model, making it challenging for such companies to thrive by monopolizing data. Individuals would gain more control over their web content and decide who can access and profit from their personal data.
In contrast, Web 3.0 business opportunities are likely to revolve around leveraging this newfound ability to customize web products and services for individuals. For instance, Web 3.0's marketing capabilities could enable companies to strike a better balance between privacy and personalization than the current web allows. However, they might encounter challenges, given Web 3.0's robust privacy protections, which could alter their existing digital marketing strategies.
The enhanced transparency offered by immutable blockchain ledgers could enhance customer service by providing both parties with access to transaction records. Businesses could streamline their supply chains by utilizing decentralized applications to dismantle data silos and monitor suppliers' activities. Real-time information sharing among supply chain participants could mitigate shortages and expedite deliveries.
Additionally, Web 3.0 plays a crucial role as the infrastructure for the metaverse, a proposed 3D virtual world where digital avatars representing people interact and conduct business. Similar to Web 3.0, the metaverse does not yet exist and is anticipated to rely on blockchain or a comparable decentralized technology for its data infrastructure and financial transactions. Artificial intelligence will also be integral, making the metaverse more responsive to users' preferences.
The metaverse and Web 3.0 are intricately connected at both technical and conceptual levels, suggesting they will likely evolve in parallel. The realization of the metaverse is contingent upon the establishment of robust Web 3.0 foundations.
How will Web 3.0 work?
In Web 1.0 and 2.0, HTML served as the foundation for webpage layout and delivery. This foundational role will persist in Web 3.0, but its interaction with data sources and the location of these sources are likely to evolve.
In the realm of Web 2.0, many websites and almost all applications relied on centralized databases to deliver data and facilitate application functions. However, Web 3.0 will shift towards using decentralized blockchains, eliminating the need for arbitrary central authorities. This democratic approach to creating and validating information theoretically grants users greater control over the web and the usage of their personal data.
Another significant distinction between Web 2.0 and Web 3.0 lies in the role of AI and machine learning. Web 3.0 will empower these technologies to play more prominent roles in delivering tailored content to users, moving away from content curated by others. While Web 2.0 allowed users to contribute and occasionally collaborate on site content, Web 3.0 is poised to entrust these tasks to the Semantic Web and AI.
This shift will result in a more "intelligent" and responsive web environment. Data will be logically organized within the Semantic Web structure envisioned by Berners-Lee for the web's first version, with AI demonstrating enhanced understanding.
The rise of the decentralized autonomous organization (DAO) in today's blockchain and Web 3.0 communities could revolutionize web management. By wresting control from central authorities and placing it in the hands of self-governed digital communities, this emerging governance mechanism could reshape the web landscape.
Moreover, Web 3.0 relies fundamentally on cryptocurrency instead of traditional government currency. Consequently, financial transactions will occur on decentralized blockchains rather than through existing financial service companies.
Both Web 1.0 and Web 2.0 predominantly utilized the IPv4 addressing space. However, due to the web's substantial growth over the years, Web 3.0 will demand significantly more internet addresses, a requirement fulfilled by IPv6.
