Every hazmat-compliance scan HaulGuard records is locked into a SHA-256 hash chain.
This page fetches the chain's hashes (no driver data) and re-runs the verification
math in your browser using the Web Crypto API. If any record had been
removed, altered, or inserted post-hoc, the link breaks at that point and you'll
see a red X with the broken event. Don't trust us — let your own machine check.
Scan-specific verification
Verifying audit chain for scan
Click Run verification to fetch the chain and re-hash every link in your browser.
That is the same check an inspector can run at roadside, on their own phone, without an account and without taking our word for it that the chain is intact. Every scan writes a link into this chain, and the evidence packet for that scan carries a QR that resolves here.
Showing up to 200 events (the first 200 matching your filter, if one is set). The link check compares each event's prev_hash to the previous event's self_hash. Mismatch ⇒ chain has been broken.
