Zero-Knowledge Proofs Explained: Prove Secrets Without Revealing Them

What if you could prove something is true without exposing the secret that makes it true? This video explains zero-knowledge proofs with simple examples, then connects them to privacy, blockchains, digital identity, and verification. You’ll learn the core intuition behind zero-knowledge proofs, what provers and verifiers do, why completeness, soundness, and zero knowledge matter, and where this technology fits into future systems.
