Security
Cryptography proving statements without revealing underlying data.
Zero‑knowledge techniques enable one party to prove knowledge or correctness without exposing secrets. They power privacy, identity, and scalability systems.
Frequently asked questions
What can zero knowledge do?
Prove correctness or membership without revealing the secret data, improving privacy and scalability.Where is it used today?
Rollups, identity credentials, private voting, and verifiable computation.What are the limits?
Proof generation can be heavy and circuits are hard to design. Use vetted libraries and patterns.
