Generate an image. Hallmark stores the bytes and a canonical, hash-verified provenance manifest in Backblaze B2, so the origin of the file stays checkable long after it leaves this page.
Drop any image here. Hallmark hashes the bytes and looks that hash up in the B2 registry, and separately reads any manifest embedded in the file itself. The two answers are reported separately — a registry hit proves origin, an embedded manifest alone does not.
