Zero Check Protocol

Definition

A zero check protocol is a cryptographic mechanism that verifies whether a committed value is zero without revealing the value itself. This protocol is a fundamental building block in zero-knowledge proof systems, allowing a prover to demonstrate that a specific calculation results in zero, or that a particular variable holds a zero value. It ensures that certain conditions are met within a computation without disclosing the actual inputs or intermediate steps. Such checks are crucial for maintaining privacy and correctness in verifiable computations.
