Zero-knowledge proofs let one party prove a statement to another while revealing nothing beyond its truth, which sounds like wishful thinking and turns out to be real math. We walk what ZK actually proves and how, zk-SNARKs versus zk-STARKs at an engineering level, the trusted-setup problem, real applications versus hype, and the honest cost in proving and verification time.
