Verify a WHIG Evidence record

Check an Evidence Package

Choose an Evidence Package zip saved from WHIG. Its timestamps are checked here, in your browser. The package is not uploaded: the only request is for the Bitcoin block each timestamp names, from two public block explorers.

Older signed records

Records from earlier versions of WHIG were signed by WHIG’s server (ECDSA P-256) at each processing step. Paste the contents of the inventory.json from one of those Evidence Packages below to check its signatures in your browser. The signed time comes from WHIG, not an independent timestamp, and it is not when the video was filmed. This does not verify the inventory, photographs, values or later edits. Records made with the current app are not signed. Nothing is uploaded.
