Public sale mechanism for honest value discovery
Occasion Perpetuals launch by single-price clearing auctions lasting roughly quarter-hour.
The system evaluates all candidate costs to maximise matched quantity, with tie-breaking favoring minimal imbalance and costs closest to 50%.

Occasion Perpetuals function with 1x remoted margin solely, requiring consumers to deposit collateral equal to their most potential loss.
The proposal concludes that buying and selling happens inside value bands of 0.001 to 0.999, with decision oracles posting last values throughout specified problem home windows for dispute decision.
