Check it yourself

Use tokenswim-verify to check the downloaded proof.

Verify the proof

tokenswim-verify verify proof.json

And its place in the tree

tokenswim-verify checkpoint verify checkpoint.json --proof proof.json

proof.json is exported by the consumer who made this request, from this page while signed in. checkpoint.json comes from the public checkpoint repository.

Verification scope

Verification checks witness signatures, challenged offsets, chunk proofs and the model reported in the proven bytes.

Matching those bytes to the full session transcript is checked by the attestor, rather than the standalone verifier.
