Demystifying Web3: A Beginner's Guide to the Decentralized Web
Background
Main articles: 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 1989 to 2004, where most sites consisted of static pages, and the vast majority of users were consumers, not producers of content.[14][15] Web 2.0 is based around the idea of "the web as platform"[16] and centers on user-created content uploaded to forums, social media and networking services, blogs, and wikis, among other services.[17] Web 2.0 is generally considered to have begun around 2004 and continues to the current day.[16][18][5]
Terminology[edit]
Web3 is distinct from Tim Berners-Lee's 1999 concept for a Semantic Web.[19] 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.[20]
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."[1] In 2021, the idea of Web3 gained popularity.[21] Particular interest spiked toward the end of 2021, largely due to interest from cryptocurrency enthusiasts and investments from high-profile technologists and companies.[5][6] 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.[22]
Concept[edit]
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).[5] 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".[23] A policy brief published by the Bennett Institute for Public Policy at the University of Cambridge defined Web3 as "the putative next generation of the web's technical, legal, and payments infrastructure—including blockchain, smart contracts and cryptocurrencies."[24] 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.[25]
Some visions are based around the concept of decentralized autonomous organizations (DAOs).[26] Decentralized finance (DeFi) is another key concept; in it, users exchange currency without bank or government involvement.[5] 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.[27] 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.[10]
The internet you know is about to change. Buckle up and get ready for Web3, a revolutionary concept that promises a more user-centric, transparent, and secure online experience. But what exactly is Web3, and why is everyone talking about it?
Imagine a one-way street. In the early days of the internet (Web 1.0), information flowed from a small group of content creators (websites) to a vast audience of passive consumers (users). Think static web pages with limited interactivity.
Web 2.0: The Social Web (2000s)
The rise of Web 2.0 transformed the internet into a two-way street. Social media platforms, blogs, and interactive applications allowed users to generate and share content, fostering a more social and dynamic online experience. However, with this convenience came a trade-off: centralization. Large tech companies like Google and Facebook became gatekeepers, controlling vast amounts of user data and influencing online experiences.
Web3: The Decentralized Web (Present & Future)
Web3 aims to break free from this centralized control. It envisions a decentralized web, powered by blockchain technology, where users have more control over their data and online interactions. Here's what makes Web3 unique:
- Decentralization: No single entity controls the web. Power is distributed among a network of computers, making it more resistant to censorship and manipulation.
- Blockchain Technology: This secure and transparent ledger system underpins Web3, enabling secure transactions, verifiable ownership, and smart contracts (self-executing code) that automate agreements.
- User Ownership: Web3 empowers users to own their digital assets, from data to in-game items (through NFTs).
What Can You Do in Web3?
Web3 opens a new world of possibilities:
- Decentralized Finance (DeFi): Manage your finances without traditional banks through secure lending, borrowing, and trading platforms built on blockchain.
- Non-Fungible Tokens (NFTs): Own unique digital assets like artwork, music, or virtual collectibles, and trade them on decentralized marketplaces.
- Decentralized Autonomous Organizations (DAOs): Participate in and govern online communities built on shared ownership and collective decision-making.
- The Metaverse: Explore immersive virtual worlds where you can socialize, play games, and interact with digital assets.
Web3: Challenges and the Road Ahead
Web3 is still in its early stages, and there are challenges to overcome. Security vulnerabilities, scalability issues, and a lack of user-friendly interfaces require ongoing development. Additionally, regulatory frameworks need to adapt to this evolving landscape.
Despite the challenges, the potential of Web3 is undeniable. It's a future where users are empowered, data is secure, and the internet is a more open and democratic space. As Web3 continues to evolve, it's an exciting time to be a part of the digital revolution.
