Introduction
The evolution of Web3 depends on seamless interoperability, enhanced scalability, and robust privacy. Polyhedra Network addresses these critical needs using state-of-the-art zero-knowledge proof (ZKP) systems. By providing trust-minimized and highly efficient infrastructure, the platform enables secure asset transfers, message passing, and data sharing across diverse Web2 and Web3 environments.
Comprising top engineers and researchers from leading institutions like UC Berkeley, Tsinghua University, and Stanford University, Polyhedra Network focuses on creating a comprehensive suite of ZKP-based solutions. These innovations are designed to support the next generation of decentralized applications and systems.
Why Interoperability Matters in Web3
Interoperability—the ability for different blockchains, protocols, and systems to communicate and work together—is fundamental to the growth of Web3. As the ecosystem expands, connecting various blockchains, Metaverses, and internet applications becomes increasingly important.
However, achieving secure interoperability remains challenging. Existing cross-chain solutions often rely on trust assumptions, making them vulnerable to security threats. Over the years, bridge attacks have resulted in significant financial losses, highlighting the need for more secure and decentralized alternatives.
Core Solutions by Polyhedra Network
zkBridge: Trustless Cross-Chain Interoperability
Polyhedra Network’s zkBridge offers a trust-minimized and efficient infrastructure for interoperability between Layer-1 and Layer-2 blockchains. By leveraging zero-knowledge proofs, zkBridge verifies consensus validity without relying on external trust assumptions. This approach enhances security while reducing on-chain verification costs.
The platform utilizes deVirgo, a distributed proof system, to accelerate proof generation. It also employs recursive proofs to minimize verification expenses. zkBridge’s testnet already supports multiple blockchain networks, including Ethereum, BNB Chain, Polygon, and Cosmos.
For blockchains with light client protocols, zkBridge compiles these protocols into zk-SNARK circuits, ensuring correct execution with minimal verification effort. Its modular architecture supports diverse applications, such as token bridging, message passing, and cross-chain computational logic.

Distributed Proof Generation Network
To optimize proof generation, Polyhedra Network developed deVirgo, a distributed proof system based on Virgo. By incorporating distributed sumcheck and polynomial commitment techniques, deVirgo achieves optimal parallelism, significantly speeding up proof generation.
In practical terms, deVirgo makes zkBridge up to 100 times faster than single-threaded proof systems. Additionally, the platform created paraPlonk, a generalized distributed proof system compatible with Plonk-based ZKP variants. paraPlonk minimizes communication overhead between nodes while maintaining full compatibility with existing protocols.
This technology supports large-scale distributed proof generation networks, enabling fully decentralized zkRollup and zkEVM implementations. It allows developers to migrate existing Plonk-based systems with minimal modifications.
zkDID: Privacy-Focused Decentralized Identity
zkDID is Polyhedra Network’s solution for scalable and interoperable decentralized identity (DID). By combining soul-bound tokens (SBTs) and verifiable credentials with ZKPs, zkDID enables privacy-preserving identity verification for billions of internet users.
The system uses stealth address mechanisms and zero-knowledge proofs to give users fine-grained control over their personal information. Users can selectively reveal data to specific systems without compromising privacy. zkDID leverages smart NFT containers to connect credential issuers with Web2 and Web3 applications, ensuring compatibility with W3C standards and various data types.
Integrated with zkBridge, zkDID facilitates seamless data interoperability across different systems, simplifying communications between all parties involved in decentralized identity management.
