Verifiable data
Check a proof
Every signed artefact we issue carries an Ed25519 signature over its payload. This page recomputes that signature here, in your browser, and tells you whether the document in front of you is the one we signed. Nothing is uploaded, and the public key is editable — swap in your own copy and the result no longer depends on trusting us at all.
The algorithm is published as data at /v2/proof/recipe, so you can implement this check in any language rather than reading ours. Everything else that can be checked.
Paste it exactly as you received it. The signature covers the bytes as written, so reformatting the file — even re-indenting it — is itself a change.
Fetched from our public key endpoint for convenience. Replace it with your own copy and the check is no longer taking our word for anything.
What a matching signature does not tell you
It establishes that the document is unaltered since we signed it. It says nothing about whether the backtest inside it is any good — that is what the six criteria are for, and on most runs several of them read “not reported”. A signature is a chain of custody, not a quality mark.
