Polyhedra is building the foundation for the future of intelligence. This is more than an ambitious vision. It is a commitment to transforming digital infrastructure by unlocking exponential improvements in computational power and seamless interoperability across systems.
The latest milestone in this mission is the launch of EXPchain, a transformative platform designed to usher in the next era of AI and verifiable computation. With the EXPchain testnet now live, developers can explore groundbreaking possibilities in preparation for the mainnet launch, scheduled for Q1 2025. What makes it different from the rest? Find out below.
The Everything Chain for AI
At the heart of empowering intelligence is trust. But trust alone is not enough. It must be proven. Polyhedra has created a transparent, scalable, and secure network that brings verifiability to machine learning and AI-driven processes.
EXPchain provides a groundbreaking capability: proving the validity of outcomes without exposing sensitive details about how those outcomes were generated. This approach is critical in deploying AI across high-stakes industries like healthcare, finance, and beyond.
When AI models make decisions, whether diagnosing a patient or recommending an investment, accuracy and transparency are paramount. EXPchain ensures these decisions are verifiable without compromising the privacy of the models or the data they rely on.
Core Technologies: The Backbone of EXPChain
EXPchain is Polyhedra’s cutting-edge Layer 1 public chain, integrating state-of-the-art technologies such as the Expander Proof System, zkPyTorch, and smart proofs (Proof of Intelligence). These innovations redefine what’s possible at the intersection of AI and blockchain.
The Expander Proof System
Zero-knowledge proofs provide a way to prove something is true without revealing sensitive underlying data. As the fastest zero-knowledge proof (ZKP) system available today, Expander combines the Goldwasser-Kalai-Rothblum (GKR) protocol with novel polynomial commitment schemes. It achieves linear prover time, reducing computational overhead while maintaining performance.
As a leading application of this technology in safety and performance, Expander can prove 15,000 Keccak-f permutations per second on consumer-grade platforms like the Apple M3 Max and AMD 7950X3D CPUs, all while maintaining an impressively low memory footprint.
zkPyTorch Integration
Seamlessly embedding ZK proofs into AI workflows, zkPyTorch enables efficient, privacy-preserving interactions between AI models and blockchain. This creates a framework for building scalable, verifiable, and secure AI applications.
Cross-Platform Interoperability
Expander also enhances Ethereum-compatible applications such as zkBridge, enabling trustless interactions across blockchains with unparalleled efficiency. This makes cross-chain staking and AI-powered processes seamless and secure.
A Vision for the Future
With the testnet now live, EXPchain is set to redefine the landscape of AI and blockchain. By leveraging the power of zero-knowledge proofs, Polyhedra is building the foundation for a future where these technologies converge seamlessly, unlocking transformative possibilities for industries worldwide.
