Web Evolution

Blockchain is one of the most transformative technologies of the 21st century. Before exploring how it works, let's trace its roots - back to the evolution of the Internet and the World Wide Web.

Note
Definition

The World Wide Web (WWW) is a system of interconnected documents and resources linked by hyperlinks and URLs. Created by Sir Tim Berners-Lee in 1989, the web has evolved from static pages into a dynamic, intelligent, and decentralized ecosystem.

Three Phases of the Web

  1. Web 1.0 - The Static Web:
    • Focused on reading, not interaction;
    • Websites were simple HTML pages without user input or collaboration;
    • Users consumed information but couldn't modify or contribute;
    • Browsers like Netscape Navigator and Internet Explorer made the Internet accessible to the public.
  2. Web 2.0 - The Social and Interactive Web:
    • Users began to create and share content, not just consume it;
    • Rise of social media (Facebook, YouTube), blogs, and collaborative platforms like Wikipedia;
    • Introduced cloud computing, which enabled real-time collaboration and global connectivity;
    • However, this era brought centralization - large companies gained control of user data.
  3. Web 3.0 - The Decentralized Web:
    • Represents a shift back to user ownership and data sovereignty;
    • Aims for trustless systems with blockchain at the core;
    • Integrates AI and semantic understanding to deliver more personalized experiences;
    • Examples: Bitcoin, Ethereum, Ripple, and Litecoin challenge traditional finance and empower users directly.

Web evolution has moved from static information delivery to social interaction - and now toward decentralization and trustless collaboration. Blockchain is a key pillar of this new Web 3.0 era, enabling secure, transparent, and user-driven systems.
