Zero-Knowledge Proofs

    A zero-knowledge proof (ZK protocol) is a mathematical proof and method that enables the “prover” to prove to a “verifier” that they know specific information without revealing what this information is. This makes zero-knowledge proof ideal for scenarios where privacy and security are paramount, such as checking that an encrypted password matches the verifier’s key without revealing the password. An example of a zero-knowledge proof is in the use of privacy-focused cryptocurrencies, such as Zcash, to offer blockchain transactions that have increased levels of privacy for their users.
