Abstract

An outcome reported by a first prediction market can be determined. A state root hash from a given block in a block chain created during or after a resolution process of the first prediction market can be obtained. A proof that the value of an outcome obtained from the block chain is the same as reported by the first prediction market can be determined by: identifying a set of nodes within a cryptographic structure that forms a path from a top node to an outcome node containing a value of the outcome; and hashing the outcome node with any adjacent nodes and intervening nodes until a hash of the top node is obtained. Responsive to the hash of the top node matching the state root hash, the proof can be submitted to a second prediction market to resolve the second prediction market.
