Protect Yourself: Documenting Vehicle Condition for Accidents, Rentals, and Sales

Whether it's an accident, a hit-and-run, returning a rental or car-share, or selling a used car, disputes about a vehicle's condition almost always come down to one question: what did it actually look like, and when? Here's what's worth photographing.

Why a timestamp helps

A photo's own metadata can technically be edited, so "this is what it looked like when I picked it up" or "this is what it looked like at the scene" can always be second-guessed. Proof Stamp anchors the hash of each photo — a fingerprint of its exact content — into the Bitcoin blockchain, giving you an independently verifiable record of when that exact file existed, checkable by anyone (an insurer, a rental company, a buyer) without having to trust you or them.

  1. Upload your photos or dashcam clip as soon as you can after the incident, pickup, or sale.
  2. The hash is computed automatically and the Bitcoin timestamp process begins.
  3. Once confirmed, download the originals, the proof data, and a verification report anytime a dispute comes up.

Report to the right people too. For accidents, that usually means the police and your insurer; for a hit-and-run, the police as soon as possible. Documentation supports those reports — it doesn't replace them.

Start preserving evidence for free

Proof Stamp does not verify or vouch for the truthfulness of any uploaded data's content. It functions as a mechanical timestamping infrastructure that objectively records, in a form independently verifiable by third parties via the Bitcoin blockchain, that data existed at a given point in time.
