Privacy protection in Web3 may seem complex, but the core contradiction is simple— you want to hide your identity, but also need to be trusted. How can these two be coordinated?

Complete invisibility is not difficult. The challenge is to make others believe you without revealing personal information. For example, in bank loans, you don't need to disclose all your account data, but you can prove that you meet the lending requirements; for property ownership verification, you don't need to publicly disclose all assets, just demonstrate your purchasing ability. The same applies in Web3.

This is the essence of Practical Privacy. Zero-knowledge proofs make this possible—you can prove "you meet certain conditions" without revealing "what your identity is." Holding enough tokens? Just prove it, no need to disclose your wallet. Meeting a qualification? Generate a proof, and privacy remains entirely in your control.

This on-chain verification mechanism is changing the privacy paradigm in Web3. It's not an either/or choice, but about finding a balance between transparency and privacy.
