Odaily News According to official news, the Proof Cloud of the Polyhedra Network team has entered the Beta stage, and a platform called "Proof Arena" has been released, through which developers can test various proof systems in a controlled environment to evaluate the performance of proof systems for specific proof generation tasks. Proof Arena will allow creators of ZK proof systems to compare their systems with other systems in a transparent and scientific way while ensuring that all controllable variables remain unchanged. The initial stage of the project will generate benchmarks for Polyhedra's "Expander" ZK proof system, Polygon's Plonky3, StarkWare's Stwo, and Linea's Gnark.
