RECORD FLOW
The athlete scans the gym's QR code, reads the gym's waiver and signs it on their own phone.
When the payment is completed, the signed waiver is sealed and issued as a PDF, with its SHA-256 hash recorded at issuance.
Each sealed record is linked by its hash to the record sealed before it in its chain, so a later change to a chained record is detectable. The chain covers the signed waiver's data, not the PDF file.
After each day closes (UTC), a Merkle root is computed over the latest record of every chain; it also takes in the previous day's root. The first root is for 5 October 2026. The roots are kept in Waiver2.0's own database; they are not time-stamped outside it.
Anyone with the PDF and its Contract ID can check at waiver2.com/verify whether the file matches the record for its waiver; the check compares the file's SHA-256 hash with the value on record, not the chain. The file stays on their device; only its SHA-256 hash is sent, with the Contract ID.
When something goes wrong in a gym, the waiver is only half the story. The other half is the moment itself: the equipment, the floor, the setup, the time. Waiver tools record the signature. Camera apps record the moment. Media Capture Documentation is designed to join the two: in its code, the athlete records the incident from their phone, inside waiver2.0, and it is designed to be sealed when it reaches our server, in a record for the incident that is linked to the waiver they signed. It is part of Premium, which cannot be chosen at present.
Photos and video are taken with the camera of waiver2.0's incident page. Each file is marked as taken with that camera or added with the file button, as the app reports it; our server does not check where a file came from.
Each file is designed to be hashed (SHA-256) when it reaches our server and recorded with its own hash, so that a later change to the file would be detectable.
The time is set by waiver2.0's servers, not by the phone's clock, which anyone can change.
Every capture is kept in a record for the incident, linked to the athlete's sealed waiver.
If a file ever stops matching its seal, it is designed to be reported to the waiver2.0 operator for review.
| An ordinary phone photo | Media Capture Documentation |
|---|---|
| Can be edited or filtered afterwards | Designed so that a change after it reaches our server would be detectable |
| Date and time come from the phone, which can be changed | Time set by waiver2.0's servers |
| Can be taken later or picked from the gallery | Taken in the app, marked as camera or file as the app reports it |
| Sits on a personal phone, apart from the waiver | Designed to be sealed on receipt, in a record linked to the signed waiver |
Evidence is clearest in the first minutes after an incident and hardest to recreate later. Premium, which cannot be chosen at present, is the plan in which the athlete adds photos and video of an incident, designed to be sealed when they reach our server, to a record linked to the sealed record of what they agreed to, kept by an independent record-keeper rather than by either side.
As part of Media Capture Documentation, Premium, which cannot be chosen at present, also includes i-Witness eyewitness (a person who saw the incident, added to the report as an eyewitness), the i-Witness Signature Field (a signature image for the eyewitness, given in the app), the Liability Timeline engine (the records of an incident, set out in order of server time; it is designed to record the order of events, not to decide who is liable) and the Insurance-Ready Export (the incident record as one PDF, to share with an insurer if the athlete chooses; what the insurer does with it is for the insurer to decide). None of these is offered at present. Compare plans.
How any evidence is weighed is always for the court to decide.
WHY WAIVER2.0
When an injury claim reaches a gym, the first questions are simple: what exactly did the athlete sign, when, and has the document changed since? A one-page form in a drawer rarely answers them. waiver2.0 is built to: each waiver is written for the gym's jurisdiction, sealed at signing, and kept unchanged by an independent record-keeper.
A record that stays exactly as it was signed.
waiver2.0 is an independent third-party record-keeper. It is not a party to the waiver, takes no side in any dispute, and does not certify facts. It records what was signed, when, and how — and preserves it unchanged.
