zero-knowledge proof

plural zero-knowledge proofs

1. computingAn interactive method for one party to prove to another that a (usually mathematical) statement is true, without revealing anything other than the veracity of the statement.

   Implementation of a zero-knowledge proof significantly improves the privacy and security of many systems. However, it introduces additional costs in processing power and hard drive space.

   This issue of privacy in blockchain isn't new, and many ideas have been proposed, such as keeping the data off-chain and using zero-knowledge proofs (ZKPs) to prove we did the right computation (e.g., Aleo and Aztec) or using mixnets to anonymize transactions (e.g., Tornado Cash).
