Verify a ZetaVault Video

ZetaVault publishes each official video with two things: a visible mark in the corner (the ZetaVault logo and the address zetavault.ai/verify), and a SHA-256 hash — a unique fingerprint of the exact file. If even a single byte of the video changes, the fingerprint changes completely. That is what makes it useful for telling an authentic original from an altered copy.

Official video fingerprints

Below are the SHA-256 fingerprints of the official ZetaVault hero video. The web file is the version served on our homepage; the master file is the full-quality original. A legitimate file will match one of these exactly — the two encodings are different files and have different fingerprints.

How to check a video yourself

You do not need any special software. Every computer can calculate a file's SHA-256 fingerprint with a single built-in command. Download or save the video file first, then follow the steps for your system.

On Windows — open PowerShell (press the Start button, type “PowerShell,” and open it), then type this, replacing the path with the location of your file:

Get-FileHash -Algorithm SHA256 "C:\path\to\video.mp4"

On macOS or Linux — open the Terminal app, then type:

shasum -a 256 /path/to/video.mp4

Each command prints a long string of letters and numbers. That string is the file's fingerprint. Compare it — character for character — against the official fingerprint published in the section above. Letter case does not matter; the sequence of characters does.

Note: many websites and messaging apps automatically re-compress videos when you upload or forward them. That re-compression changes the file, so a video passed through another platform may not match even if it started as our original. For a true check, verify a file downloaded directly from ZetaVault.

What the mark means and how to report a suspected fake

The ZetaVault mark identifies a video as content presented under the ZetaVault name and directs viewers to this verification page. The mark is a visible notice, not proof by itself: logos, names, voices, and likenesses can all be copied. Verification comes from comparing the file’s SHA-256 fingerprint with the official fingerprint published by ZetaVault.

A matching fingerprint confirms that the file is byte-for-byte identical to the original file ZetaVault published. A nonmatching fingerprint means only that the file is different. It may have been edited, shortened, re-encoded, compressed by another platform, or created by someone else.

If a video appears to impersonate ZetaVault, Aldric Zenn, or another ZetaVault officer, do not rely on the visible mark alone. Check the file against the fingerprints published above and confirm that the source directs to the official zetavault.ai domain.

To report a suspected impersonation, altered video, or fraudulent use of a ZetaVault identity, send the video or a link to it, together with the location where you encountered it, to authenticate@zetavault.ai. Please do not forward suspicious files more widely than necessary, as forwarding services may alter the file and make direct comparison more difficult.

ZetaVault will review reports against its published originals and available publication records. Verification can establish whether a file matches an official original; it cannot, by itself, determine who created an altered version or what their intent was.
