What Are Zero-Knowledge Proofs? Complete Beginner’s Guide-7.67

Zero-knowledge proofs are one of the more abstract and fascinating concepts in applied cryptography today. From potentially being applied to nuclear disarmament talks to providing anonymous and secure transactions for public blockchain networks, zero-knowledge proofs are a profound example of cryptographic innovation.

The concept of zero-knowledge proofs was first introduced in 1985 by Shafi Goldwasser, Charles Rackoff, and Silvio Micali and actually appeared in The New York Times in 1987. They designed the notion of knowledge complexity, a metric for the amount of knowledge that is needed to transfer from a prover to a verifier for it to be considered valid.
