A Zero-Knowledge Proof is a brilliant piece of math that lets you prove you know a secret without actually telling the secret to anyone. Imagine you want to prove to a website that you are over 18 years old, but you don’t want to show them your ID or your birthdate. A Zero-Knowledge Proof would let you “prove” you are an adult with 100% certainty without giving away any private information. In crypto, this technology is used to keep transactions private and to help networks process thousands of transactions per second.
