Zero Knowledge Proofs in 60 seconds

Set your stopwatch... Let's go!

What are they?

ZK-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) is a form of zero-knowledge proof that allows one party (the prover) to prove to another party (the verifier) that a statement is true, without revealing any information beyond the validity of the statement itself.

ZK-SNARKs are based on a mathematical concept called a "zero-knowledge proof," which allows one party to prove the truth of a statement without revealing any information about the statement itself. The key advantage of ZK-SNARKs is that they are "succinct," meaning that the proof can be verified quickly and without the need for a large amount of computational resources.

What will their impact be?

In the context of online interactions, ZK-SNARKs have the potential to change the way we think about privacy and security. For example, imagine that you want to prove your age or identity to an online service, but you don't want to reveal your full name, birthdate, or other personal information. With ZK-SNARKs, you can prove your age or identity without revealing any additional information.

Furthermore, ZK-SNARKs can be used to build more privacy-preserving protocols, such as private transactions on a blockchain, where the amount and the parties involved in a transaction remain private. And also they can be used in voting systems, where the voter’s identity remains private while ensuring that the vote is counted only once.

Summary

ZK-SNARKs are a powerful tool for building privacy-preserving systems and protocols and have the potential to change the way we interact online by enabling new types of secure and private interactions.
