Huggingface-Passport

Model Passport gives AI models a verifiable identity. For a pinned Hugging Face revision, it builds a deterministic manifest, commits its content root and lineage on Base Sepolia, resolves it via ENS, and indexes it with The Graph. Anyone can inspect provenance and replay the recipe from committed off-chain artifacts.

Model Passport pairs a Python CLI with a zero-dependency judge UI. It resolves pinned Hugging Face revisions, canonicalizes manifests, and recomputes SHA-256 content roots locally. A Solidity registry on Base Sepolia anchors lineage; ENS enables discovery, while a The Graph subgraph exposes verification evidence.
