4.2 Web 3.0 Semantic Web
Web 3.0 layers cryptographic identity and shared ledgers on top of the web. It pushes ownership and trust down from platforms to users, but adds latency, cost and UX friction. This lesson maps the stack and shows where it actually fits.
The Web 3.0 Stack
Figure 5.3 - A simplified five-layer view of the Web 3.0 stack.
Where Web3 Actually Fits
| Use Case | Good Fit? | Why |
|---|---|---|
| Verifiable receipts and certificates | Yes | One-time write, public verification |
| Cross-border micro-payments | Yes | Removes correspondent banking friction |
| Token-gated communities | Yes | Native wallet authentication |
| High-volume social feeds | No | Latency and gas costs |
| Real-time multiplayer games | No | Block times slower than user expectation |
| Storing PII | Avoid | Public ledger, hard to redact |
Engineer Takeaways
Web 3.0 is not a replacement for Web 2.0. Treat the blockchain as an append-only verification layer that complements - rather than replaces - your relational database and message queue.
