How it is checked

  1. 01

    In your browser

    The signatures and hashes are recomputed here, from the receipt alone. Nothing is uploaded.

  2. 02

    Against Intel and NVIDIA

    The chip's statement is checked against Intel's certificates, and the GPU's against NVIDIA's.

  3. 03

    On Ethereum

    The version is read from the registry only the artist can write to; the payment from the Runs contract.
