The resolution layer for event markets
Event markets are not fungible because nobody publishes what an event means or who is accountable for the call. RainMuin publishes the definition, the receipt and the forecaster record — free to implement, free to cite.
Event Definition v1
Ordered data sources, fallback, rounding, reference time, edge cases and a dispute window — versioned and machine-readable.
Read the definitionResolution Receipts
Source URL, evidence snapshot hash, observer, resolver and a permanent permalink for every settlement.
Open the ledgerForecaster Passports
Brier skill with a 90% cluster-bootstrap interval, shrinkage and domain gates — a record no model can fabricate.

Schema, identifiers and methodology are published under CC0. Resolution determination, custom mandates and certification are licensed — the standard is free, the registry is the product.
