  1. Data Privacy in Web3: Meeting 2025 Consumer Expectation

  2. Introduction Web3 promised user data control, but 2025 consumers expect more: • Transparency • Granular consent • Strong security This presentation explores how businesses can meet these expectations.

  3. 2025 Consumer Expectations • Users want clear, granular consent. • Demand for transparency on data use. • High sensitivity for identity & financial data. • Trust depends on demonstrable control & accountability.

  4. Web3: Opportunity & Risk Opportunities: • Decentralized identity. • Verifiable credentials. • On-chain proofs without revealing data. Risks: • Public ledger exposes metadata. • Hard to comply with deletion requests. • Regulatory pressure rising.

  5. Key Privacy Technologies • Zero-Knowledge Proofs (ZKPs): Verify facts without sharing raw data. • Verifiable Credentials: Selective data sharing. • Off-chain Storage: Keep sensitive data off-chain, anchor proofs on-chain. • Wallet Privacy: Address rotation, minimal telemetry.

  6. Regulation Catching Up • European Data Protection Board issued blockchain privacy guidelines. • Compliance needed for GDPR & other global rules. • Cross-border data laws impact design choices.

  7. Meeting Expectations: Practical Steps 1. Transparent data flows. 2. Selective disclosure by default. 3. Minimize on-chain personal data. 4. Improve wallet privacy. 5. Conduct privacy impact assessments. 6. Get independent audits. 7. Communicate simply & clearly.

  8. Privacy as a Growth Lever • Treat privacy as a differentiator. • Premium tiers with privacy features. • Partner with trusted issuers. • Use privacy as part of onboarding & marketing.

  9. Friction & Trade-offs • ZKPs can be expensive to compute. • UX for decentralized identity is still new. • AML rules vs privacy balance is tricky.

  10. Checklist for Product Teams • Use ZKPs and verifiable credentials. • Store minimal off-chain data. • Harden wallet privacy. • Run DPIAs and audits. • Monitor regulations continuously.

  11. Measuring Success You meet expectations if: • Users can easily control & revoke data access • Data flows are transparent & verifiable • Privacy reduces real-world harms like profiling & identity theft

  12. Final Note • Start small, measure impact, invest in one standout privacy feature, and explain it simply. • This will build trust and adoption in Web3 in 2025.
