About Lanveris
Lanveris is a chain-neutral trusted timestamp proof and file-verification service built and operated by Shanghai LanCun Technology Co., Ltd.
Why Lanveris exists
Agent outputs and creative deliverables move quickly between tools, people, and organizations. Screenshots and filenames are weak evidence of when exact bytes existed or whether they later changed.
Lanveris calculates file fingerprints locally, anchors batch roots with independent RFC 3161 timestamp authorities, and exports portable credentials for public verification or CLI verification after trust roots have been cached.
What we provide
Lanveris provides evidence of exact file bytes, trusted time, registered metadata, and integrity. It does not grant copyright, decide authorship, or determine whether media is genuine or lawfully used.
Original files are not uploaded during registration or web verification. The platform stores fingerprints and the metadata required to operate and verify records.
