how it works
Capture. Prove. Share.
1 · Capture
QorCap is the one app you run, on Windows, during the match. It records the capture card and fingerprints the video as it is written: every segment is hashed and chained, with timestamped checkpoints. It stays light, so it doesn't strain your laptop.
controller button log in the same session · since v0.3.02 · Prove
After the final whistle, QorTime works on the finished recording. It re-checks the fingerprints, reads the score, and seals a signed receipt. The AI referee reviews the evidence and signs a verdict: accept, dispute, or abstain, with plain reasons and the evidence frames.
3 · Share
Send the receipt to your opponent, a tournament, or a platform. Anyone can check it in the free browser verifier, and nothing is uploaded. A hosted referee countersign, Verified Match, is in test-mode early access.
Inside the Prove step
- Integrity checks in code: video fingerprints, checkpoint chain, and signatures. Scores can only move in legal football steps, never backwards. The clock only runs down within a quarter. The final screen must match the last score.
- AI referee: reads frames to confirm the score. It only accepts a reading when it is confident and the reading agrees across several frames, and it abstains rather than guessing. Tampering is caught by the integrity checks, not by trusting a model.
- Honest limit: QorTime proves the footage's integrity and timing (and, since QorCap v0.3.0, the controller inputs from the same session). It does not prove who held the controller.
01 / capture
The scorebug, read off the screen.
QorTime's scorebug reader reads the final score from the recording, digit by digit, and only locks when consecutive frames agree.
- frames read from the capture card
- score locked on frame agreement

SEALEDIllustrative scorebug, not a real match. No league or publisher marks.
02 / challenge
Prove a human is on the sticks.
At random moments the referee sends a nonce. The player pauses and enters the pattern, which must show up in the controller input log and on video within 600 ms. Bots and replays don't get a second try.
QorCap logs the controller since v0.3.0. Since v0.3.11 a challenge only opens when Madden lets you pause: after the kickoff and a play call, never during a kickoff.
03 / co-sign
Every few seconds, the referee signs the clock.
A rolling hash of frames and inputs goes to the referee about every 4 seconds. It timestamps and countersigns each checkpoint, chaining them. A receipt forged later can't carry signatures from the past.

04 / seal
The receipt prints. Everyone signs.
At the final whistle each player's agent signs the result and the referee seals it. If both players run agents and their timelines agree, the receipt is dual-attested.

QorTime proves the footage's integrity and timing. Controller inputs from the same session are logged by QorCap since v0.3.0. It does not prove:
- Account sharing: who is physically holding the controller.
- Collusion: both players agreeing to throw or fake a match.
- Anything outside what the capture card saw.
