A smart contract (800) includes a bond issuing unit (832) and a bond collecting unit (833). The bond issuing unit (832) determines whether or not a payment amount to be paid by an exchange floor, who is a buyer, to a user, who is a seller, can be paid with a deposit amount of a deposit wallet of the exchange floor, and if the payment amount cannot be paid, issues to the user, a bond equivalent to a currency amount which is at least a part of the payment amount, stores the currency amount of the bond in a bond wallet, and registers the user in a creditor list. When there is currency-putting-in into the deposit wallet of the exchange floor, as the currency-putting-in becomes a trigger, the bond collecting unit (833) selects a creditor registered in the creditor list, and compares a put-in-currency amount with the currency amount of the bond which is issued to the creditor. When at least a part of the currency amount of the bond can be paid back with the put-in-currency amount, the bond collecting unit (833) pays back at least the part of the currency amount of the bond to the creditor with the put-in-currency amount.

The present invention relates to a virtual-bond collecting device, which collects a virtual-bond, in a distributed ledger network.
Conventionally, it has been impossible to make an exchange which requires more than one's own currency, by using virtual currency. When the exchange that requires more than one's own currency is executed, a transaction is not allowed, and thus, the exchange cannot be registered in blockchain.
On the other hand, the virtual currency has a system of its own currency which is called a token, and the token can be issued uniquely and sent to another person. There is a method of recording an exchange such as gold or stock by adding additional information to bitcoin called a colored coin which is the token. A method is proposed in which a securities exchange such as a bond or a bill is managed with blockchain by using a method of the colored coin (Patent literature 1 and 2).
