Overview
A zk-STARK is a transparent zero-knowledge proof with no trusted setup and quantum resistance. It is larger than SNARKs but simpler to trust. It is used in high-throughput systems.
How It Works
STARKs generate large proofs that are fast to verify, with no trusted setup ceremony. Their transparency removes setup risk. They are suitable for batch verification.
Why It Matters
zk-STARKs power scalable systems like Starknet and can be verified efficiently. Their lack of trusted setup is a security advantage. Their size is a trade-off.
