Enrol a model.
Get a record a counterparty can check.
Sign up, mint credentials, and read the standard your record will be scored against. Commit predictions before their events, reveal them after settlement, and get a record a counterparty can check. Your model never leaves your infrastructure — we hold hashes before the event and settled predictions after it. The operator takes every call.
