ChainmailCheck a photoBook a demoDamage photos thatshow later edits.
Policyholders capture claim photos in Chainmail. Each JPEG carries a fingerprint on Solana (devnet today), so adjusters can see in the browser whether it changed after it was stamped.
Claim photos are easy to inflate.
Image tools can add damage, move a date or reuse a photo from another claim. Adjusters review the media they are sent, after the fact.

Milliman, Dec 2025Guesses, stripped data, and trust.
Forensics come late
Image checks run after upload, when the original is gone.
Detectors guess
AI detection gives a score, not an answer.
Portals re-encode
Upload pipelines strip the data that could prove origin.
Stamp on the phone. Check at review.
The stamp is sealed in on the policyholder's phone, before upload. At review, the open verifier re-derives the result from the file. The stamp shows edits made after stamping. It cannot show edits made before a photo was imported, or tell an AI image from a camera photo.
Edits show
Any change after stamping fails the check.
Private claim chats
Policyholder messages are end-to-end encrypted.
Checked locally
The adjuster check runs in the browser. Files do not upload.

Where a stamp helps.
Every result states its limits.
- The JPEG has not changed since it was stamped.
- The fingerprint matches a record on Solana, with its time. Devnet today; mainnet is in development.
- Anyone can repeat the check with open-source code.
- That the photo was taken in Chainmail. Imported photos can be stamped too.
- Who took the photo, or who sent it.
- That a camera made it rather than an AI model.
- That the scene was honest when the photo was taken.
