ChainCatcher news, Polyhedra Network announced the latest upgrade of the Expander toolbox: the Expander Compiler Collection (ECC). The ECC is designed to convert circuits written in gnark into an intermediate representation (IR) of layered circuits. This technology significantly optimizes proof times while ensuring compatibility with existing solutions. In addition, the ECC has achieved a key breakthrough in compatibility with existing circuit languages, enabling developers to generate GKR proofs at a faster pace.
