What is a zk-STARK in Blockchain?

A zk-SNARK (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) is a cryptographic proof that allows one party to prove to another that they know a value without revealing the value itself.

A zero-knowledge proof is a cryptographic method by which one party can prove to another that a statement is true without revealing any information beyond the validity of the statement itself.

Zero-knowledge proof: Cryptographic method proving a statement true without revealing info. Enhances privacy and security in blockchain.

A zk-Rollup is a Layer 2 solution that bundles transfers using zero-knowledge proofs for scalability and privacy by validating transaction batches.
