Odaily Planet Daily News - Polyhedra Network, as a pioneer in blockchain and artificial intelligence innovative technologies, recently announced the launch of the Layer 1 public chain EXPchain testnet. EXPchain aims to revolutionize the intersection of artificial intelligence (AI) and blockchain by enabling AI verification on the blockchain through zero-knowledge machine learning (zkML), addressing key challenges in AI safety, data privacy, and verifiability. EXPchain employs advanced zero-knowledge proof (ZKP) technology, positioning itself as the 'Omni-Chain of AI', with core technologies including: 1. Expander proof system: providing unprecedented performance and scalability, supporting efficient implementation of ZKP across various applications. 2. zkPyTorch integration: embedding zero-knowledge proof capabilities directly into traditional AI workflows, simplifying the development process. 3. Smart proof (PoI): establishing a verifiable trust model for AI models, ensuring responsible and transparent AI development.
