Polyhedra Network is establishing cornerstone technology for trust and scalability in AI and blockchain systems with EXPchain Layer 1. We’ve purpose-built this platform to support zero-knowledge machine learning (zkML), addressing critical challenges in AI safety, data privacy, and verifiability. In the evolving AI ecosystem, this breakthrough infrastructure sets a new benchmark by enabling privacy-preserving, verifiable, and scalable AI applications.
EXPchain incorporates our pioneering research in zero-knowledge proof (ZKP) technologies – the Expander proof system to ensure high-performance, zkPyTorch to streamline zero-knowledge proof capabilities into traditional AI workflows, and Proof of Intelligence (PoI) to establish an immutable chain of trust for AI models – to greatly reduce barriers for developers to build scalable trust into AI applications.
Our product ecosystem, including zkBridge, zkLightClient, and Proof Cloud, extends trust and interoperability across networks with secure, efficient cross-chain communication. These solutions lay the groundwork for a unified ecosystem where developers, businesses, and communities can innovate confidently.
To mark the release of EXPchain on Testnet, our next contribution in building the future of intelligence, we’ve taken a moment to recap on the team and technology that got us to this point.
