    IPC: G06Q20/38

    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.

    IPC: G06Q50/18

    Abstract: A control method includes: obtaining first transaction data that includes first information on a first contract made between a first user and a second user; storing the first transaction data obtained into the distributed ledger; obtaining second transaction data that includes second information on a second contract made between the first user and a third user; storing the second transaction data obtained into the distributed ledger; obtaining third transaction data using the first information and the second information, when one of the first transaction data and the second transaction data is associated with a remaining one of the first transaction data and the second transaction data, the third transaction data including third information on a third contract made between the second user and the third user; and storing the third transaction data obtained into the distributed ledger.

    Abstract: 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.
