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 method for controlling one of a plurality of voting servers in an electronic voting system is provided. The method includes receiving, from a terminal, transaction data including voting data, and generating, using a processor, a block including the transaction data and dummy transaction data. The dummy transaction data including dummy voting data that is not associated with the voting data. The method further connects the generated block to a blockchain, the blockchain being stored in a memory.

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 malfunction information indicating that one of the IoT devices is malfunctioning, and time information indicating a time when the IoT device has obtained the malfunction information; transferring the obtained first transaction data to second servers different from the first server; executing, together with the second servers, a first consensus algorithm for an agreement on an authenticity of the first transaction data; 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: A system for managing a transaction of an item between first and second users includes a first lock attached to the item, a storage unit having a second lock attached thereto and physically storing the item, and a processor that manages a first privilege to open the first lock and a second privilege to open the second lock. The processor performs management so that a holder of the first and second privileges is the first user. Upon receiving, from the storage unit, information indicating the second lock being opened, the processor performs management so that a first transaction is concluded in which the first user tentatively receives the item from the second user. Upon receiving, from the first lock, information indicating the first lock being opened, the processor performs management so that a second transaction is concluded in which the first user inspects the item and finally receives the item.

Abstract: A management system includes: a right holder information storage unit which stores right holder information about a right holder entitled to use a delivery locker device; an agreement formation unit which creates a block of a blockchain that includes a processing instruction, and stores the block into a block storage unit; a terminal device which transmits an assignment processing instruction; a process execution unit which, when obtaining the assignment processing instruction included in the block, updates the current right holder included in the right holder information; and a condition checking unit which, when determining that the condition for assignment fails to be met, creates a return processing instruction and transmits the return processing instruction to the agreement formation unit. When obtaining the return processing instruction included in the block, the process execution unit updates the right holder information.

Abstract: Various devices, methods, and media are provided. According to one of the devices, an unlocking request for unlocking a lock is received. The lock is provided in a container and contains a physical object. Information of a first owner, that has a right of ownership of the physical object, is acquired from a first ledger when the unlocking request is received. The first ledger is one of a plurality of distributed ledgers which each have a same content. The device determines whether the first requester matches the first owner, and causes the lock to be unlocked when the first requester matches the first owner.

Abstract: An authentication server authenticates a voter using authentication data including a first identifier (ID) associated with the voter and authentication information regarding the voter. The authentication server further synchronizes a first blockchain. The first blockchain includes first transaction data indicating that the voter has been authenticated with one or more of other authentication servers. A voting server receives, from a terminal, voting data including a second ID associated with a vote cast by the voter and voting information indicating the vote. The voting server synchronizes a second blockchain including, as second transaction data, the voting information included in the voting data with one or more of other voting servers. The terminal transmits the authentication data to the authentication server and, after the authentication is successfully completed, transmits the voting data to the voting server.
