Lesson 6 – Principle 4: Privacy by Default

Privacy is normal not a luxury.

Privacy in DeFi is often treated as optional. But true DeFi Punk puts it front and center.

Without privacy, users are exposed to surveillance, profiling, and even physical risks. Protocols should shield IPs, wallet linkages, and transaction histories automatically.

Examples:

  • Aztec Protocol → ZK privacy built-in.

  • Plain DeFi apps → transactions fully exposed.

Reflection Prompt:
  Does your app protect privacy by default, or do you need extra steps?

Scoring:

  • 0 = no privacy

  • 1 = optional privacy

  • 2 = privacy by default
