What Is Zero-Knowledge Proof
A zero-knowledge proof is a cryptographic method that lets one party prove to another that a statement is true without revealing the underlying information itself. In blockchain and digital systems, this means you can demonstrate that you know or hold certain data, like a password, credential, or balance, without exposing the data to others.
ZK proofs work by using complex math to generate a proof that can be verified quickly, even though the verifier never sees the secret information. This enhances privacy and security, allowing validation without disclosure. Zero-knowledge techniques are widely used in privacy-focused blockchains, identity systems, and scalability solutions.
Beyond privacy, zero-knowledge proofs can help reduce onchain data load by allowing verifiers to check correctness off-chain and confirm results onchain with minimal information. This makes transactions faster and cheaper while protecting sensitive data.
