Abstract: A distributed ledger system is constructed by communicably connecting distributed ledger nodes that each of a plurality of organizations has, and is capable of executing a smart contract. The smart contract manages information in a distributed ledger while building consensus among the distributed ledger nodes of the plurality of organizations. The distributed ledger node executes the smart contract according to a transaction received from another device, such as a client node of an organization. The smart contract receives a soundness monitoring result that is information acquired by a first organization monitoring soundness of the distributed ledger node of a second organization, verifies the soundness of the distributed ledger node of the second organization by verifying the received soundness monitoring result, and records a soundness verification result that is a result of verifying the soundness, in the distributed ledger.
