Zusammenfassung:	A service server generates a first smart contract programmed to be capable of executing provision of an incentive to a user when a goal indicated by generated challenge content generated is achieved (S12), generates first transaction data including the first smart contract, and transmits the data to a first authentication server. The first authentication server executes a consensus algorithm and records the first transaction data in a distributed ledger to run the first smart contract (S13). The first authentication server notifies a device used by the user of the challenge content (S14). The first authentication server obtains, from the device, second transaction data including first challenge content selected to be registered by the user (S15), and records the second transaction data in the distributed ledger by executing a consensus algorithm (S16).
