Polyhedra Network, a cross-chain solution provider for L2s and L1s with zkBridge technology, has made an exclusive development. The platform disclosed that it has recently open-sourced its exclusive ZK proof mechanism Expander which it launched nearly 6 days back. The company revealed this news on its official account on X.
🎉 Today, we are proud to open source #Expander, the world’s fastest #ZK proof system.
Expander is a GKR prover designed for scaling large-scale parallel computing.
Now, everyone can access the record-breaking open-source prover:https://t.co/DP25yI80SM pic.twitter.com/c99Fb9etjq

Polyhedra Open Sources Its ZK-Proof Mechanism ‘Expander’
The platform noted in one of its posts that Expander operates as a GKR prover. As per Polyhedra, the project focuses on scaling broad-scale parallel computing by its design. As a result of this facility, everyone can leverage the unique open-source prover. The company added that its GKR prover pays considerable attention to speed.
In addition to this, Expander natively supports AVX and ARM Neon instruction sets. Keeping that in view, the consumers can select them in line with their CPU specifications. It revealed that the project can prove nearly 4500 keccak hashes every second in the case of an M3 Max CPU. On the other hand, concerning the x86 benchmark, it advised the users to wait for further announcements.
It noted that the respective development will prove to be another revolutionary step. Apart from that, the company discussed the exclusive features of Expander. It added that the project specifically targets developers who require ultimate speed regarding ZK technology and so on. The chief technologies of Expander take into account GKR-based prover. It operates for a constant period while processing.
The Project Features New Functionalities to Facilitate Developers
Moreover, it also includes a polynomial commitment that is based on the expander code. While mentioning the main feature of Expander, Polyhedra claimed that it originates from the co-founders’ former works. They comprise Libra and Orion. The former offers concise zero-knowledge proofs by leveraging Optimal Prover Computation. The latter uses Zero Knowledge Proof by utilizing Linear Prover Time.
While moving on, Polyhedra also provided an overview of the unique features that the latest project offers. One of these features is a lookup table. Expander also provides CUDA GPU acceleration as another prominent feature. Furthermore, the initiative enables the consumers to leverage MPI integration in the case of distributed computing. Along with that, it also offers support for zkML and zkVM. Interested developers can contact the platform.
