Invisible watermark + on-chain receipt in 5 lines of code Dual hashes (exact + perceptual) → survives compression & edits Full creator anonymity — only a random wallet address is shown Tiered verification: Strong/Medium/Weak/None OpenAPI spec → TypeScript client in one command Live contract, Python client, verifier, tests, docs — everything is already there
C2PA is mostly future, commercial tools are closed and expensive. PoG is Apache 2.0, deployed today, costs ~$0.001, and you can verify any image with a single drag-and-drop. Gasless relayer coming Q1 2026. Looking for contributors on the relayer, browser extension, and getting ComfyUI/A1111/InvokeAI to ship it by default.
PS. Stars are real momentum — every star helps us become the default open standard, so appreciate every star.
