What is Web 3 0

The concept of a World Wide Web based on public blockchains. For the concept based around machine-readability, also called Web 3.0, see Semantic Web.

Web 3 (also known as Web 3.0 and sometimes stylized as web3) is an idea for a new iteration of the World Wide Web based on blockchain technology, which incorporates concepts such as decentralization and token-based economics. Some technologists and journalists have contrasted it with Web 2.0, wherein they say data and content are centralized in a small group of companies sometimes referred to as "Big Tech". The term "Web3" was coined in 2014 by Ethereum co-founder Gavin Wood, and the idea gained interest in 2021 from cryptocurrency enthusiasts, large technology companies, and venture capital firms.

Some experts argue that Web3 will provide increased data security, scalability, and privacy for users and combat the influence of large technology companies. Others have raised concerns about a decentralized web, citing the potential for low moderation and the proliferation of harmful content, the centralization of wealth to a small group of investors and individuals, or a loss of privacy due to more expansive data collection. Others, such as Elon Musk and Jack Dorsey, have argued that Web3 only serves as a buzzword.

History of the World Wide Web and Web 2.0

Web 1.0 and Web 2.0 refer to eras in the history of the World Wide Web as it evolved through various technologies and formats. Web 1.0 refers roughly to the period from 1991 to 2004, where most sites consisted of static pages, and the vast majority of users were consumers, not producers, of content. Web 2.0 is based around the idea of "the web as platform" and centers on user-created content uploaded to forums, social media and networking services, blogs, and wikis, among other services. Web 2.0 is generally considered to have begun around 2004 and continues to the current day.

Terminology

Web3 is distinct from Tim Berners-Lee's 1999 concept for a semantic web. In 2006, Berners-Lee described the semantic web as a component of Web 3.0, which is different from the meaning of Web3 in blockchain contexts.

The term "Web3" was coined by Polkadot founder and Ethereum co-founder Gavin Wood in 2014, referring to a "decentralized online ecosystem based on blockchain." In 2021, the idea of Web3 gained popularity. Particular interest spiked toward the end of 2021, largely due to interest from cryptocurrency enthusiasts and investments from high-profile technologists and companies. Executives from venture capital firm Andreessen Horowitz traveled to Washington, D.C. in October 2021 to lobby for the idea as a potential solution to questions about regulation of the web, with which policymakers have been grappling.

Some writers referring to the decentralized concept usually known as "Web3" have used the term "Web 3.0", leading to some confusion between the two concepts. Furthermore, some visions of Web3 also incorporate ideas relating to the semantic web.

Concept

Specific visions for Web3 differ, and the term has been described by Bloomberg as "hazy", but they revolve around the idea of decentralization and often incorporate blockchain technologies, such as various cryptocurrencies and non-fungible tokens (NFTs). 6 Bloomberg has described Web3 as an idea that "would build financial assets, in the form of tokens, into the inner workings of almost anything you do online". Some visions are based around the concept of decentralized autonomous organizations (DAOs). 25 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.
