Lymark

Proof of work

The photo that ends the argument on WhatsApp.

Time, date and address on the image, so the group can see them. And the original file, checkable if someone doubts it.

Strip enlarged here: in the real photo, the eye cannot see it.

Matches is not the same as intact: it is the same scene, within the hash tolerance.

In the app, the photo is taken like with any camera.

The stamp is a statement by whoever issued it. What gets verified is where the file came from and the moment.

Address pulled on the spot, adjustable with one tap before you save. The group gets the photo; checking the file uses the original.

What Lymark does — and does not

On the device

The photo never uploads

The server keeps email and plan. Never the image, never your location. The account exists so the subscription can.

The check

Intact or it doesn’t match. That’s all.

Intact, no seal, or mismatch. Whoever checks sees that. It happens on this device.

Honest limit

Not a notary

Time and address on the stamp are the photographer's declaration. The file can be checked. It does not stand in for public faith.
