Abstract
A node of a C company verifies transaction data received from a node of a B company, the transaction data proposing addition of a subject substance to a restriction list. When the node of the C company determines that information indicating that a new proposed subject substance falls under a restricted substance is incorrect by obtaining data on the restricted substance, for example, from the outside (a server apparatus or the like in an external group) and checking whether or not the subject substance falls under the restricted substance, the node of the C company does not approve the proposal for addition of the new subject substance to the restriction list but transmits transaction data that denies the proposal to the node of the B company (an arrow B).
