Web3 is an emerging concept that defines the next generation of the internet, integrating blockchain technology, artificial intelligence, and augmented/virtual reality environments known as the Metaverse. This article aims to provide an educational overview of Web3, covering its history, definition, examples, core components, and the difference from Web 2.0. Let’s dive in!
The term Web3 was first mentioned in 2006 by Tim Berners-Lee, the inventor of the World Wide Web. He described Web3 as an autonomous, intelligent, and open internet. The phrase gained popularity when New York Times journalist Jeffery Zeldman included it in a blog article. Originally, Web3 was known as the semantic web, which has already been achieved through widespread integration.
It was in 2014 that Gavin Wood, co-founder of Ethereum, associated the term Web3 with applications built on blockchain technology. Since then, Web3 has become widely used to refer to various new-age internet-based technologies.
Web3 refers to the next generation of the internet that utilizes decentralized protocols based on blockchain technology. It aims to address the issues of data ownership and control, offering solutions to the limitations of the current internet era.
In the current internet landscape, large technology companies act as intermediaries, dictating the services users can access. However, Web3 operates on a decentralized network, eliminating the need for permission and middlemen. Individuals have the power to provide services to each other, owning and controlling their internet experience.
Web3 solutions are already making progress, with notable examples like Decentralized Finance (DeFi). DeFi allows transparent exchanges of financial products using blockchain, without relying on traditional intermediaries like banks. The DeFi industry is valued at over $200 billion and is expected to grow further.
Other examples of Web3 applications include artificial intelligence tools like Wolfram Alpha and Apple’s Siri. Wolfram Alpha is a knowledge engine that answers questions and analyzes information using expert-level knowledge and algorithms. Siri, on the other hand, is a voice assistant that automates tasks and provides information to users.
Web 2.0, the current generation of the internet, emerged in 2004 and focuses on user-generated content and interaction. It enables people to create, retrieve, and share their own content through platforms like YouTube and Facebook. However, big tech companies control a significant portion of the internet, resulting in privacy concerns and limited user control.
Web3 holds immense potential for transforming various industries and aspects of our lives. Some of the possibilities include:
As Web3 continues to evolve, it will require collaboration between developers, entrepreneurs, policymakers, and users to address technical, legal, and ethical challenges. The future of the internet lies in the hands of a decentralized, user-centric, and privacy-preserving Web3 ecosystem.
