Chiquito is a high-level structured language for implementing zero knowledge proof circuits, currently being implemented in the DSL Working Group of PSE. It is a state machine zk-language that provides better syntax and abstraction. It can automatically compiler arbitrary boolean expressions for state machine transitions. It can optimise the resulting arithmetization. Chiquito has a Halo2 backend, which is a low level zkDSL that writes circuits using the PLONKish arithmetization and is working on supporting additional backends. Chiquito circuits can be written using both Python and Rust.
