I've been thinking about on-chain identity recently, and it's quite interesting—why must we choose between privacy and identity?

Traditional solutions are either completely anonymous or require revealing all information, with no middle ground. But zero-knowledge proofs have changed this situation.

With ZK technology, you can prove that a certain identity attribute is true without revealing the specific information. For example, prove you're over 18 without disclosing your birth date; prove you've passed KYC without uploading your passport.

This is the true future of on-chain identity—privacy and trustworthiness are no longer at odds but integrated. It can protect personal data while meeting compliance requirements within the ecosystem.
