Zero-Knowledge Proof

ELI5 — The Vibe Check

A Zero-Knowledge Proof lets you prove you know something without revealing what you know. Prove you're over 18 without showing your birthday. Prove you know a password without sending the password. It's a cryptographic magic trick where the verifier learns nothing except that the statement is true.

Real Talk

Zero-Knowledge Proofs (ZKPs) are cryptographic protocols where a prover demonstrates knowledge of a value to a verifier without conveying any information apart from the fact that they know the value. ZK-SNARKs and ZK-STARKs are practical implementations used in blockchain privacy and identity verification.
