Information processing device, information processing method, and computer-readable recording medium storing information processing program

An information processing method that is executed by an information processing device corresponding to any one of a plurality of processes regarding a source of a profit among a plurality of information processing devices that manages a distributed ledger, comprising:

• storing a first smart contract that converts an actual value in the process regarding a purpose into an index value that indicates a contribution degree to the purpose, based on a unified criterion in the plurality of processes, according to a record type of the actual value, for each of the plurality of processes;
• storing a second smart contract that calculates a ratio at which the profit obtained from the source is distributed to a plurality of participants that shares the plurality of processes, based on the index value;
• registering first trail data that indicates a correspondence relationship between the any one process, the actual value in the process regarding the purpose, and the record type of the actual value, in the distributed ledger;
• calculating the index value regarding the process, according to the record type of the actual value in the process regarding the purpose, by using the first smart contract that corresponds to each process, based on a token that indicates a correspondence relationship between the source and trail data registered in the distributed ledger for each process, with reference to the distributed ledger;
• and
• calculating a ratio at which the profit obtained from the source is distributed to the plurality of participants, according to the calculated index value regarding each process, by using the second smart contract.
