2. In Web 3.0 world, there can be blockchain - based social networks.
3. Web 3.0 is operated by users collectively rather than a corporation.
Which of the statements given above are correct?
- (a) 1 and 2 only
- (b) 2 and 3 only
- (c) 1 and 3 only
- (d) 1, 2 and 3
Answer: (d) 1, 2 and 3
Explanation
Web 3.0 — the decentralised web
| Web stage | Feature |
|---|---|
| Web 1.0 | Read-only static pages (1990s) |
| Web 2.0 | Read-write, social media; data held by big platforms |
| Web 3.0 | Read-write-own; built on blockchain; users own data and assets |
Checking the statements:
| Statement | Verdict | Reason |
|---|---|---|
| 1. People control their own data | Correct | Data and identity sit with users, often in crypto wallets |
| 2. Blockchain-based social networks can exist | Correct | Examples: Lens Protocol and Farcaster |
| 3. Run by users collectively, not a corporation | Correct | Governed by DAOs (decentralised autonomous organisations) and token holders |
Answer: (d) 1, 2 and 3.
Why each option is right or wrong
- (a) Incorrect. It leaves out collective user operation, the core idea of decentralisation.
- (b) Incorrect. It leaves out user control of data, the main promise of Web 3.0.
- (c) Incorrect. It leaves out blockchain-based social networks.
- (d) CORRECT. Web 3.0 gives users control of data, enables blockchain social networks and is run collectively.
Key point
Web 3.0 = read-write-own web on blockchain; users own data; governed collectively (DAOs), not by corporations.
Remember
Web 3.0 lets users own their data, run blockchain networks and govern collectively.
Common mistakes
- Confusing Web 3.0 with the Semantic Web idea of the 2000s.
- Thinking blockchain is only for crypto money; it also powers social and identity apps.
- Assuming Web 3.0 still depends on central servers like Web 2.0.
Exam tip
1.0 read, 2.0 read-write, 3.0 read-write-own.
