Control method, mobile node, and recording medium

A control method includes: obtaining first transaction data that includes a first variable indicating first information on a first contract made between a first user and a second user, and a second variable set to a predetermined value indicating second information is undetermined; storing the first transaction data into the distributed ledger; executing storing processing of reading out the second variable, and storing it into a rewritable storage in a server; obtaining second transaction data that includes a third variable indicating third information on a second contract made between the first user and a third user, and a change command for changing the second variable, based on the third variable; storing the second transaction data into the distributed ledger; and executing change processing of changing, according to the change command, the second variable from the predetermined value, after the second transaction data is stored into the distributed ledger.

Control method, device, and recording medium

A control method includes: receiving first transaction data related to a sign-up for service and storing the first transaction data received into the distributed ledger included in each of the plurality of servers, the service offering, if a goal condition predetermined for the service is satisfied, a token to a participant that is a user who signs up for the service; storing, into the distributed ledger, second transaction data indicating that the user is offered the token predetermined for the service, if it is determined that the goal condition is satisfied; and storing, into the distributed ledger, third transaction data indicating that the user is offered a deposit that is a temporary token predetermined for the service, at a predetermined timing included in a period from the storing of the first transaction data into the distributed ledger until when determination of whether the goal condition is satisfied is performed.

Control method, data structure, server, and recording medium

A control method of a fund management system including a plurality of servers that hold a distributed ledger, and executed by one of the plurality of servers, includes: receiving transaction data, the transaction data pertaining to payment processing for payment of a token from one or more applicants of crowdfunding to a management account, and storing the transaction data that is received in the distributed ledger held in each of the plurality of servers; determining, using a smart contract, whether or not a target condition of the crowdfunding is met; and outputting information indicating a result of the determining.

Control method, fund management system, recording medium, and data structure

A control method is executed by a first server among a plurality of servers in a system including the plurality of servers and a generating device that generates record information about usage records for users belonging to one group when a service provided by a business operator is used on a group basis. The method includes: obtaining, from the generating device, first record information about a first usage record of a service by a first user belonging to the one group; determining whether the first record information obtained is permitted under a rule based on contract content, stored in the first server, of a contract entered into by the first user and the business operator; and forwarding first transaction data including a determination result to a plurality of second servers and storing a first block including the first transaction data in a distributed ledger managed by the first server.

Control method, server, and recording medium

An action estimation device includes: an obtainer that obtains sound information pertaining to an inaudible sound, the inaudible sound being a sound in an ultrasonic band collected by a sound collector; and an estimator that estimates an output result, obtained by inputting the sound information obtained by the obtainer into a trained model indicating a relationship between the sound information and action information pertaining to an action of a person, as the action information of the person.

Action estimation device, action estimation method, and recording medium

A control method includes: receiving transaction data that includes (i) peer information used for connecting a first peer among peers in a P2P system to another peer among the peers and (ii) a signature added to the peer information by the first peer; verifying the received transaction data using the signature included in the transaction data; and storing the transaction data into the distributed ledger when the verifying is successful.

A control method that, in an information management system including a plurality of servers each having a distributed ledger, is executed by a server from among the plurality of servers, includes: receiving first transaction data that includes identification information and permission or non-permission information, the identification information being associated with user information that is managed in the information management system and relates to a first user, the permission or non-permission information indicating whether provision of the user information to a second user is permitted; and storing the first transaction data received, in the distributed ledger in each of the plurality of servers.

Control method, server, recording medium, and data structure

A cloud server () receives environmental information of respective installation sites of a plurality of appliances () via a network (), and determines one or more appliances that are installed in a same room among the plurality of appliances (), based on the received environmental information.

Information providing method and information providing apparatus

A control method according to the present disclosure includes: receiving, from a terminal operated by a first user who is one of parties that have concluded a first contract, first transaction data that includes a first smart contract corresponding to the first contract and a first electronic signature associated with the first user; executing a consensus algorithm with a plurality of other servers; and recording a block including the first transaction data in a distributed ledger. The first smart contract includes (i) content of the first contract which is a main contract, (ii) a variable that is provisional and used for identifying a second smart contract corresponding to a second contract which is to be newly concluded as a sub contract of the first contract, and (iii) a condition for creation of the second smart contract.
