Zero-knowledge interoperability infrastructure, Polyhedra Network (ZKJ) announced the release of the latest upgrade to its Expander toolbox—the open-source Expander Compiler Collection (ECC).
The Expander Compiler Collection (ECC) is designed to transform circuits written in gnark into an intermediate representation (IR) of layered circuits. This IR forms the basis for generating proofs using the Expander prover, allowing builders to easily create GKR proofs for gnark circuits.
At the core of the ECC is the optimization power of the GKR protocol, specifically designed for layered circuit representations. The ECC enables the conversion from R1CS to layered circuits, ensuring compatibility with existing community solutions and achieving advanced proving times. With the integration of ECC, the Expander toolbox is now fully compatible with current R1CS-based solutions, enhancing the future potential of cryptographic proof generation.
This technology significantly optimizes proof generation time while maintaining compatibility with existing solutions. Additionally, ECC’s compatibility with current circuit languages represents a key breakthrough, enabling builders to generate GKR proofs more efficiently. Furthermore, according to Polyhedra Network, invoking the compiler requires minimal code, typically fewer than ten lines, making the integration process straightforward.
Join the revolution with the open-source Expander Compiler Collection (ECC)! Our latest tool in the Expander ecosystem lets you seamlessly transform gnark circuits into efficient layered formats. It’s time to join the future of proof systems with ECC.https://t.co/4VdOLVQ0zW pic.twitter.com/EiKpv06PwF

Polyhedra Network Unveils Expander ZKP System And Its Comprehensive Roadmap
Polyhedra Network is developing zkBridge, a zero-knowledge (ZK) blockchain interoperability protocol created to facilitate cross-chain transactions. Since its roll out last year, zkBridge has enabled over 20 million cross-chain transactions and produced more than 40 million zero-knowledge proofs (ZKPs). Alongside zkBridge, Polyhedra Network has also created zkLightClient technology, integrated with the LayerZero protocol, enabling application developers to use ZKPs to secure cross-chain messages transmitted through the protocol.
The Expander is a ZKP system invented by Polyhedra Network. By combining the GKR protocol with polynomial commitment schemes, Expander achieves efficient operation with linear prover time, avoiding the high computational overhead typical of other proof systems. Recently, Polyhedra Network unveiled an extensive roadmap for Expander, aiming to support the future development of zkVM and zkML technologies.
