Abstract:
An authentication server acquires and stores, in a distributed ledger, first transaction data that indicates that a first token amount indicating the remaining amount of payment be paid from the first account of a first user to the second account of a second user (S1) and executes a first smart contract (S2). When the first token amount is larger than a second token amount that indicates the outstanding amount of the first account (Yes in S3), the first smart contract pays the second token amount to the second account (S5). Furthermore, the authentication server acquires and stores, in the distributed ledger, second transaction data that indicates that a fourth token amount be paid from the third account of a third user to the first account (S6) and executes a second smart contract (S7). The second smart contract pays the fourth token amount from the third account to the first account (S9), and the first smart contract pays the whole or part of the fourth token amount to the second account (S9).
