Ever thought about it? All those things online that require proof can actually be verified without revealing a single word of information.

There's a technology called zero-knowledge proof protocol that lets you do things like: prove your Gmail account has been active for years, show your real returns on a leading exchange, verify your frequently used Spotify account, display your completed course record on Duolingo, or even confirm your work history on LinkedIn—all without exposing any private details.

Sounds contradictory? This is actually the magic of cryptography in the Web3 era. Proof is proof, but your data remains your data—others can only see the result of "authenticity confirmed." In the field of privacy computing, this approach is redefining the rules of the game for identity verification.
