Olympic swimming captivates us with its simplicity—athletes dive, swim, and the fastest reaches the wall first. In the realm of blockchain technology, however, determining the “fastest” or most efficient is far more complex. Engineers perpetually introduce more advanced, faster systems, and the diversity of use-cases, transaction types, and performance measurement tools further complicate comparisons. This challenge also extends to designers of cryptographic tools and the various methodologies for reporting hashes per second.

Against this intricate backdrop, Polyhedra Network has introduced the “Proof Arena,” a platform crafted to serve as a proving ground for cryptographic provers. This initiative emerged from Polyhedra’s recent release of an open-source zero-knowledge (ZK) proof system, which boasted nearly double the speed of its alternatives. But the question remained—how could they substantiate this claim?

Eric Vreeland, Polyhedra’s chief strategy officer, elucidated that the team developed Proof Arena to enable developers to evaluate various provers in a controlled environment. This platform ensures that performance comparisons of proof systems for specific proof generation tasks are conducted with scientific rigor, maintaining constant controllable variables.

Proof Arena’s testing outputs include proof generation time, memory peak, and setup time, offering a detailed performance snapshot. Builders of provers are invited to submit their systems for inclusion in the arena, fostering a competitive environment.

Initially, Proof Arena will benchmark Polyhedra’s “Expander” ZK-proof system alongside Polygon’s Plonky3, StarkWare’s Stwo, and Linea’s Gnark. The team aims to support all open-source proof systems, providing benchmarks for common ZK tasks like Keccak and Poseidon hash verification across various machine configurations.

While this may sound esoteric, it holds significant importance for cryptographers and blockchain developers. Proof Arena presents a rare opportunity for these professionals to showcase and verify the capabilities of their systems in a structured, transparent setting.
