What this proves — and what it does not

A positive verdict means the PDF's SHA-256 matches a report we registered at the time of issuance. It is evidence of provenance and integrity of the document itself. It is not an endorsement by GaugeH2 of the underlying project, nor a statement about the accuracy of the inputs the user supplied.

How report verification works

Every report sealed by GaugeH2 carries a SHA-256 fingerprint of its bytes, registered when it is issued. This page computes the fingerprint of your PDF in your browser and looks it up in that register: the file itself never leaves your computer.

If a single byte of the report changed after it was issued, the fingerprint no longer matches, and the page says so.

Frequently asked questions

Do I need an account?

No. Verification is public and free, so that a bank or a client can check a report they have received.

What does a match show?

That the file is the one GaugeH2 issued and has not been altered since. It says nothing about whether the project’s assumptions are right: those are the ones declared by the author of the calculation.

Which reports can be verified?

The LCOH, TEA and Monte Carlo reports sealed by GaugeH2.
