Abstract: 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, 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. The first authentication server notifies a device used by the user of the challenge content. The first authentication server obtains, from the device, second transaction data including first challenge content selected to be registered by the user, and records the second transaction data in the distributed ledger by executing a consensus algorithm.

Abstract: A control method to be performed by a first mobile node disconnected from a mobile line among a plurality of mobile nodes each being connectable to the mobile line includes: transmitting and receiving a mobile line connection status to and from each of one or more second mobile nodes via near-field wireless communication; building a MANET with the one or more second mobile nodes based on a first mobile line connection status of the first mobile node and a second mobile line connection status of each of the one or more second mobile nodes; generating, after the building of the MANET, first transaction data including at least first MANET routing information that indicates the MANET connection status of the first mobile node; and recording a block including the first transaction data into a first distributed ledger that is used for a blockchain in the MANET.

Abstract: A control method according to the present disclosure is to be executed by a system including a distributed ledger storing a smart contract obtained by programming, in an executable manner, a determination on a medical treatment made as a result of a discussion between a patient and a physician. The control method includes: obtaining condition transaction data including biological information on the patient obtained by a sensor; obtaining opinion transaction data including information on a result of a diagnosis by the physician based on the biological information; executing the smart contract based on the biological information and the result of the diagnosis included in the condition transaction data and the opinion transaction data obtained, respectively; and outputting medical suggestion information indicating a medical treatment to be given to the patient, and obtained by executing the smart contract.

Abstract: A server acquires, from a terminal owned by a user, pairing information in which a user ID for identifying the user and a mobility ID for identifying a mobility used by the user are associated with each other; continuously acquires, from the terminal, terminal position information indicating a position of the terminal and associated with the user ID; specifies a user ID of a user using the mobility that is stopped, based on the pairing information; and determines, as position information of the mobility, the terminal position information associated with the user ID having been specified.
