Understanding Web3: The Evolution of the Internet
Web3 (or Web 3.0) represents the third major phase of the internet's evolution. To grasp its significance, let's break down the journey:
Web 1.0 (1990s): The "read-only" web
- Static websites with minimal user interaction
- Examples: Basic HTML pages, early personal websites
Web 2.0 (2000s–present): The "social web"
- Interactive platforms enabling user-generated content
- Dominated by tech giants like Meta (Facebook), Google, and Twitter
- Concerns over data privacy and centralized control
Web 3.0 (Emerging): The "decentralized web"
- Powered by blockchain technology
- Returns data ownership to users
- Enables peer-to-peer transactions without intermediaries
Why Web3 Matters Now
Six corporations control 90% of Web2's data flows:
- Meta (Facebook/Instagram)
- Amazon
- Apple
- Google (Alphabet)
- Microsoft
These companies determine:
- What content users see (via algorithms)
- How personal data is monetized
- Which services are accessible
