Abstract: A control method according to the present disclosure is executed by a first server of servers in a system including one or more IoT devices and the servers. The method includes: obtaining first transaction data including operation notification information and time information from each of the IoT devices, the operation notification information including identification information on the IoT device and a notification indicating that the IoT device is operating, the time information indicating a time when the IoT device has obtained the operation notification information; transferring the obtained first transaction data to second servers different from the first server; executing a first consensus algorithm together with the second servers; and recording a block containing the first transaction data in a distributed ledger of the first server, when the authenticity of the first transaction data is verified by the first consensus algorithm.

Abstract: Provided is a control method of controlling locking or unlocking of storage using a blockchain. The control method includes: determining, when first request information indicating a lock/unlock request, that is a lock request or an unlock request, is received from a terminal, whether a keyholder identified by reading keyholder information stored in the blockchain matches an owner of the terminal that has transmitted the first request information, the keyholder information indicating a person having the authority to lock or unlock the storage; performing lock/unlock processing when the keyholder is determined to match the owner, the lock/unlock processing being processing for causing the storage to lock or unlock in accordance with the first request information; and performing first storage processing after the lock/unlock processing is performed, the first storage processing being processing of storing, in the blockchain, transaction data indicating that the lock/unlock processing has been performed.

Abstract: A control method is executed by one device among devices included in a management system. Each of the devices includes a distributed ledger and stores: a parent smart contract including an automatic generation function of automatically generating a new smart contract; and a management function of selecting and managing one of child smart contracts generated by the devices. The control method includes: generating a first child smart contract; transmitting first transaction data including the generated first child smart contract to a different device and storing the first transaction data into the distributed ledger of the one device; receiving second transaction data including a second child smart contract generated by the different device and storing the second transaction data into the distributed ledger of the one device; and managing one child smart contract in association with the parent smart contract through execution of the management function.

Abstract: First information including first contract information indicating contract content of a first contract and a provisional contract flag indicating that the first contract information is a provisional contract is received from a first terminal used by a first user who is one of two parties that have agreed to the first contract, and is stored into a ledger. The first contract information obtained from the ledger is transmitted to a second terminal used by an auditor who inspects the first contract information. A check result indicating approval or disapproval of the first contract information by the auditor is received from the second terminal. When the check result indicates approval of the first contract information, second information including the first contract information and a definitive contract flag indicating that the first contract information has been adopted as a definitive contract is obtained and stored into the ledger.
