A zero-knowledge proof is a digital protocol that allows for data to be shared between two parties without using a password or any other information associated with the transaction. In its most basic sense, a zero-knowledge proof (also commonly referred to as ZKP) can be thought of as a protocol through which a digital authentication process can be facilitated without the use of any passwords or other sensitive data. As a result of this, no information, either from the sender’s or receiver’s end, can be compromised in any way. This is quite useful, primarily since such a level of safety provides tech enthusiasts with an avenue to communicate with one another without revealing the content of their interactions with any third party.
