What is the PolyhedraZK?
Polyhedra Network is focused on developing the fastest zero-knowledge proof (ZKP) technologies for various applications, such as AI, machine learning, interoperability, gaming, and traditional finance (TradFi) at scale. Its flagship offerings include the zkBridge, Expander, and other innovative proof systems like MissileProof, Virgo, and Orion, each tailored to meet different needs for secure, efficient, and scalable blockchain interactions.
The zkBridge protocol uses zkSNARKs to enable a prover to verify that a state transition has occurred on a sender blockchain and communicate it securely to a receiver chain. The system includes a block header relay network that fetches block headers, generates proofs of their validity, and forwards them to an updater contract, which maintains the light-client state.
Expander, Polyhedra’s fastest ZK proof system, integrates the GKR protocol and innovative polynomial commitment schemes to achieve high performance with minimal resource usage, processing 5000 Keccak-f permutations per second. This makes it a powerful solution for Ethereum-compatible applications, enabling trustless cross-chain interactions.
Polyhedra also features other advanced proof systems:
- MissileProof: A succinct range proof designed for vectors, used for anonymous payments and asset auditing, maintaining a proof size of less than 1KB.
- Virgo and Virgo++: Efficient zero-knowledge argument schemes for layered circuits and arbitrary circuits, achieving fast proof generation.
- Orion: A cutting-edge proof system optimized for off-chain applications and zkEVMs.
- Libra: A high-performance proof system that prioritizes speed without trade-offs.
- Gemini: A hardware-friendly system that allows fast proof generation using specialized configurations.
- Marlin: Reduces on-chain verification costs with constant size arguments.
- Pianist: Leverages distributed computing to combine machine power for proof generation with unlimited scalability.
These solutions are designed to empower Web3 with strong interoperability, scalability, and modularity, ensuring developers can easily integrate ZK technology. Polyhedra also supports 25+ blockchains and has built an ecosystem of over 80 partners.
