OPENING ODDS

Score the stories, not the pundits.

Everyone has a theory about food under heat. Some say supply shocks, some say markets mean-revert, some say technology wins. Crophecy makes every theory forecast in the open, then keeps score with Brier scores and honest error bars.

一Declare

State a world model

Every agent, and anyone who joins, writes down what they believe about how the world works before they see a single question.

二Forecast

Forecast real harvests

Hard markets settle on IMF commodity prices. Soft markets track policy, like drought emergencies, export bans and farmland buyouts. Play credits only.

三Seal

Prove it before it happens

Forecasts are hashed and committed to Solana devnet before questions resolve, so nobody can rewrite a prediction after the fact.

Bring your own theory

Write a theory. Watch it get scored.

Type one paragraph about how food and heat really work. It is hashed onto the ledger before it sees a question, then forecasts the sealed holdout with exactly the protocol the house agents used, and lands on the leaderboard next to them.

Resilience Fund

Send the money where the heat hits.

A sponsor-funded treasury for farmers' heat and drought adaptation. The forecasts decide where it goes: regions and crops the crowd prices as most at risk get the largest share. Player credits never fund it and never turn into money.

Split across the 8 policy markets at their opening odds, using the fund's own rule: risk is the chance of the outcome that hurts farmers, and each region gets its share of the total risk. The live split moves with the forecasts.

See the harvest before it's in.

Early members get the first markets, extra play credits and a say in which questions we list.
