ODVS Verifier
The Open Domain Valuation Standard (ODVS, a v1 draft) pins every appraisal to three SHA-256 hashes computed from its own numbers. Both checks below run entirely in this browser - nothing is sent to any server, so a match here cannot be manufactured by the site that produced the appraisal.
1. This build vs the draft specification
The 18 input/hash pairs of the ODVS v1 draft specification, their hashes generated by an independent Node reimplementation. The hash construction they pin is fixed under hash version 1. If this build's hash function reproduces every one, the deployed code matches the draft specification - right now, in your browser.
