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: An electronic voting system includes a terminal, authentication servers, and voting servers. Each authentication server includes an authentication processor that authenticates a voter using authentication data, and a first synchronizer that synchronizes a first blockchain including first transaction data with at least one other authentication server. The authentication data including a first identifier and authentication information. Each voting server includes a voting processor that receives voting data including a second identifier and voting information, and a second synchronizer that synchronizes a second blockchain including the voting information as second transaction data with at least one other voting server. Each voting server further includes a block generator that connects a block including the second transaction data to the second blockchain, and a determiner that determines the block to include the second transaction data. The terminal transmits the authentication data to at least one other authentication server and transmits the voting data to one of the voting servers after authentication.
