Starky

Starky is a FRI-based STARK implementation.

It is built for speed, features highly efficient recursive verification through plonky2 circuits and gadgets, and is being used as backend proving system for the Polygon Zero Type-1 zkEVM.

Note on Zero-Knowledgeness

While STARKs can be made Zero-Knowledge, the primary purpose of starky is to provide fast STARK proof generation. As such, ZK is disabled by default on starky. Applications requiring their proof to be zero-knowledge would need to apply a recursive wrapper on top of their STARK proof with the zero_knowledge parameter activated in their CircuitConfig. See plonky2 documentation for more info.
