Data security and privacy protection have always been pain points in the crypto world. Solutions based on zero-knowledge proof technology are changing this situation — you can prove the authenticity of your bank balance, social identity, or off-chain data to a third party without revealing any actual information. This technology utilizes advanced zkTLS protocols, finding a balance between verification and confidentiality.

The application prospects of this approach are very clear: the DeFi market can achieve truly collateral-free lending based on this system, with user credit assessments no longer relying on personal data on the chain; compliance agencies can complete KYC verification in a privacy-preserving manner, avoiding data leakage risks; most importantly, this opens a new channel for collaboration between Web2 and Web3. Rather than just technological innovation, it can be seen as rewriting the old game rule of "privacy for convenience."
