Systems and methods for providing block chain state proofs for prediction market resolution

A system, comprising:

• one or more hardware processors configured by machine-readable instructions to:
• determine an outcome reported by a first prediction market, the outcome of the first prediction market being associated with a key and value, the key including an event identification of the first prediction market and the value conveying the outcome;
• obtain a state root hash from a given block in a block chain created during or after a resolution process of the first prediction market, the given block including a header, the header including the state root hash, the state root hash being a value corresponding to a state of the block chain at a time the given block was published on the block chain;
• determine a proof that the value of the outcome obtained from the block chain corresponds to that reported by the first prediction market by:
• identifying a set of nodes within a cryptographic structure that forms a path from a top node to an outcome node containing the value of the outcome;
• hashing the outcome node with a sibling node to obtain a hash of a parent node of the outcome node;
• and
• successively repeating the hashing with the parent node and any other intervening nodes between the outcome node and the top node until a hash of the top node is obtained;
• and
• responsive to the hash of the top node from the proof matching the state root hash, submit the proof to a second prediction market to resolve the second prediction market with respect to the outcome.
