Verifier Standard: Evidence That Travels With the Claim
An open standard and Python reference implementation for attaching artifacts, checking mechanisms, results, and limits to computational claims.
Field notes
The site documents a Python reference runtime whose demo checks four adversarial cases, including wrong-artifact references, bounded proof exhaustion, inflated verification claims, and revoked ancestors. It reports 17 subcommands and shows two independent JSON executions producing identical 37,393-byte outputs with the same SHA-256 digest. The page explicitly limits that result to one interpreter and operating system, leaving cross-platform determinism as an unmeasured question rather than a marketing assertion.
