    Abstract: 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.

    Abstract: A server apparatus receives a device ID indicating one electrical home appliance among one or more electrical home appliances and a gateway ID indicating that the one electrical home appliance belongs to a same owner, a same group, or a same home as the one or more electrical home appliances, determines whether or not the one electrical home appliance is a newly connected electrical home appliance, using a management database that manages device IDs indicating the one or more electrical home appliances and the gateway ID, and when it is determined made that the one electrical home appliance is a newly connected electrical home appliance, provides an information device, which is associated with the gateway ID and which differs from the one electrical home appliance, with notification information for confirming whether or not it is to be permitted to collect the log information from the one electrical home appliance.

    Abstract: Provided is a management system including vehicles and authentication servers. A vehicle includes a communication circuit, multiple electronic control units connected to an in-vehicle network, a detection circuit, and a transaction data generating circuit. The detection circuit detects a replacement of one or more electronic control units. The transaction data generating circuit generates transaction data including an identifier that uniquely identifies each of the replaced electronic control units. An authentication server includes a communication circuit, and a verifying circuit that verifies validity of the transaction data obtained by the vehicle. The authentication server also includes a recording circuit that, upon verifying that the first transaction data is valid by the verifying unit, records the transaction data in a recording device.
