  "account": "Hunch is a platform that allows users to test their hunches before wagering real money. It focuses on sports and elections, where people often rely on hunches. The platform keeps track of which source, whether it's the sportsbooks or other prediction markets, is more accurate for each game. Hunch doesn't accept bets or charge fees; it simply tests hunches using a set of rules.\n\nTo test a hunch, users input their guess in plain language. The platform then transforms the input into a typed rule that can be easily understood. The rule is verified against a schema and checked by the model to ensure it is correct.\n\nOnce the rule is set, it is tested against data from various sources, such as DraftKings, FanDuel, BetMGM, Caesars, Pinnacle, and Betfair. The rule is replayed on a series of games, and its performance is measured using a Brier score. In the case of the NBA moneyline example, Hunch's rule outperformed Polymarket by a small margin, indicating that it has learned that Polymarket is not always the most accurate source for these predictions.\n\nHunch utilizes Tatum, a blockchain infrastructure provider, to ensure that the record of the hunches and their outcomes is immutable. The platform communicates with Sui, a blockchain, through Tatum's gRPC gateway, and anchors the results on the Sui network. This ensures that the recorded results cannot be tampered with.\n\nAdditionally, Hunch uses Walrus Memory on the mainnet to store the conclusions derived from the tests. It keeps track of the performance of each hunch, including the context, sources, and outcomes. This allows the platform to learn and adjust its recommendations over time based on the results of the hunches tested.",
