Overview
Zero-knowledge identity is identity verification that proves attributes without revealing underlying data, using zero-knowledge proofs. It lets users prove facts like age or membership privately. It combines privacy with verifiability.
How It Works
A user holds a credential and generates a proof that they satisfy a condition, such as being over 18, without revealing the exact data. The verifier checks the proof cryptographically. This preserves privacy.
Why It Matters
ZK identity enables private, selective disclosure, a major upgrade over revealing full data. It supports compliance and access without surveillance. It is a leading use of zero-knowledge technology.
