BDO Evidence, a paper trail for digital provenance
A provenance-evidence service that validates C2PA content records, anchors the result in Bitcoin and a qualified timestamp, and packages the context for later replay.
Field notes
The page frames its core artifact as an Evidence Bundle rather than a bare timestamp. That bundle is described as preserving the validator version, trust lists, revocation responses, and evaluation instant alongside the content and C2PA manifest. A visible sample record, BDO-EVIDENCE-01, reports Bitcoin existence at block 912480 and a valid qualified timestamp. The site also says its verifier and source code can travel with the export, although that capability is presented as a project claim rather than demonstrated in the extract.
