Polyhedra Network Unveils 'Proof Arena' Benchmarking Platform for Cryptographic Provers

This team of cryptographers claimed their "prover" – a key component of many blockchain systems – was faster than anyone else's.

A team of cryptographers has built a platform they say will provide transparent benchmarking for anyone who wants to compare the various cryptographic "provers" out there.

The platform, called "Proof Arena," is designed to serve as, well, a proving ground for provers, which are a key component of many blockchain systems.

Just a few months ago, the Polyhedra Network team released an open-source zero-knowledge proof system – used in many setups for auxiliary blockchains (layer 2s) – that was "nearly 2x faster than alternatives."

But how did they really know?

"The community quickly latched onto this claim and began discussing the implications of faster ZK-proof generation times," Polyhedra's Chief Strategy Officer Eric Vreeland told CoinDesk in an email.

"We realized that there was a need for a standardized and controlled environment in which people evaluating the performance of various proof systems for a particular proof generation task could do so fairly and easily."

Proof Arena will allow ZK-proof system creators to compare their systems against others in a clear and scientific manner while ensuring that all controllable variables are held constant, according to a press release Wednesday.

Outputs from the testing system include proof generation time, memory peak and setup time, according to Vreeland. Here's what that might look like in a hypothetical scenario:

Builders of the provers can also submit their systems "for inclusion in the arena," Vreeland said.

Initially, the project will be set up to generate benchmarks for Polyhedra's own "Expander" ZK-proof system, Polygon's Plonky3, StarkWare's Stwo and Linea's Gnark.

"The team plans to support all open-source proof systems and will provide benchmarks for frequent ZK tasks like Keccak and Poseidon hash verification run on a variety of machine configurations," according to the press release.

That might all sound like gibberish, but for cryptographers, it's what they care about.

And the pros might like the chance to prove their worth.
