Edelman Gilad What Is Web3 Anyway


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 1989 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 generally considered to have begun around 2004 and continues to the current day. 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. 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, DC, 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.


Specific visions for Web3 differ, and the term has been described by Olga Kharif as "hazy", but they revolve around the idea of decentralization and often incorporate blockchain technologies, such as various cryptocurrencies and non-fungible tokens (NFTs). Kharif 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". According to Liu, Zhuotao, et al (2021), three fundamental architectural enablers of Web3 were identified as a combination of decentralized or federated platforms, secured interoperability, and verifiable computing through distributed ledger technologies. 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.


Academic researchers, such as Tomer J. Chaffer and Justin Goldston in 2022, have described Web3 as a possible solution to concerns about the over-centralization of the web in a few "Big Tech" companies. Some have expressed the notion that Web3 could improve data security, scalability, and privacy beyond what is currently possible with Web 2.0 platforms. Bloomberg states that skeptics say the idea "is a long way from proving its use beyond niche applications, many of them tools aimed at crypto traders". The New York Times reported that several investors are betting $27 billion that Web3 "is the future of the internet". Some Web 2.0 companies, including Reddit and Discord, have explored incorporating Web3 technologies into their platforms. On November 8, 2021, CEO Jason Citron tweeted a screenshot suggesting Discord might be exploring integrating cryptocurrency wallets into their platform. Discord announced they had no plans to integrate such technologies and that it was an internal-only concept that had been developed in a company-wide hackathon.


Some legal scholars quoted by The Conversation have expressed concerns over the difficulty of regulating a decentralized web, which they reported might make it more difficult to prevent cybercrime, online harassment, hate speech, and the dissemination of child pornography. Some other critics of Web3 see the concept as a part of a cryptocurrency bubble, or as an extension of blockchain-based trends that they see as overhyped or harmful, particularly NFTs. Some critics have raised concerns about the environmental impact of cryptocurrencies and NFTs. Cryptocurrencies vary in efficiency, with proof of stake having been designed to be less energy intensive than the more widely used proof of work, although there is disagreement about how secure and decentralized this is in practice. Others have expressed beliefs that Web3 and the associated technologies are a pyramid scheme. Jack Dorsey, co-founder and former CEO of Twitter, dismissed Web3 as a "venture capitalists' plaything". Dorsey opined that Web3 will not democratize the internet, but it will shift power from players like Facebook to venture capital funds like Andreessen Horowitz.
