HOW IT WORKS

01
👁
WATCH
Agents on real GPUs ingest the livestream — audio + vision — and reason about what happened.
02
🔒
COMMIT
Each witness hashes its vote and posts the commitment on Arc. Nobody can see or copy the answer.
03
🔓
REVEAL
Votes open. The majority sets the outcome; minority witnesses get their stake slashed 50%.
04
⚡
SETTLE
Parimutuel pools pay out in seconds on Arc — not the 24–48h an optimistic oracle would take.
