What is a Zero-Knowledge Proof

The idea of zero-knowledge proofs, or simply ZKP for short, is a means of proving knowledge of certain information, without revealing that information. These proofs are typically used in areas, such as cryptography, where providing some information would compromise other information, and the only acceptable outcome is demonstrated proof that the prover knows certain information to be true (or false). Zero-knowledge proofs are provably correct and are based on a logician’s definition of knowledge.

In this blog, we will provide an Explanation to clear things up regarding Zero-knowledge proofs and their uses

What are Zero-Knowledge proofs used for?

ZKP was first described in 1985 by MIT researchers Shafi Goldwasser, Silvio Micali, and Charles Rackoff as a way of proving statements about computations without revealing the details of any specific computation. Zero-knowledge proofs can be used in many different applications. They can be used to prove that a statement is true without revealing anything else about it or what led to it being true. For example, they can be used to prove that someone owns an identity without revealing their private key or password. They can also be used to prove that data has not been tampered with by showing that any changes would be detectable.

As you can already notice, Zero-knowledge proofs are particularly useful in situations where you want to prove something without revealing sensitive information. The sender and receiver don’t need to know each other’s identities or how they communicate, but can still complete their transaction securely.

Zero-knowledge proofs are useful for many applications. Some examples include:

Encryption: Zero-knowledge proofs allow for encryption in which only the intended recipient can decrypt the message. This allows for private communication that does not compromise the identity of either party.

Authentication: Zero-knowledge proofs allow you to prove your identity without revealing anything about yourself or your actions. This enables secure login systems such as those used by banks and other financial institutions.

Originality: Zero-knowledge proofs allow you to prove the originality of digital assets such as music and art (NFTs).
