Zero-Knowledge Scalable Transparent Arguments of Knowledge: a cryptographic proof system enabling verification of computations without revealing underlying data. Unlike ZK-SNARKs, STARKs require no trusted setup, are conjectured to be quantum-resistant, and scale efficiently for large witness sizes, making them foundational for Layer 2 blockchain rollups and privacy-preserving computation.

Overview
- ZK-STARKs provide zero-knowledge proofs without trusted setup requirements, offering transparency and quantum resistance. StarkWare pioneered STARK technology powering StarkEx and Starknet, a permissionless Ethereum validity rollup. The zero-knowledge proof market was valued at 7.59 billion by 2033. Over $28 billion sits in ZK-based rollups, with Starknet processing over 10 million transactions monthly.
