If it is recognized as valid, the candidate block is linked to the previous blockchain, and the transaction information (transaction history) included in the block is recognized or approved as valid.

The exchange server 80 obtains the game user ID from the second database 83 based on the trader ID extracted from the trade information including its exchange ID among the trade information of the game item blockchain 10 which is validly approved. , Together with the game item information, is transmitted to the game server 50.

The control unit 51 of the game server 50 performs owner change processing of the corresponding item in accordance with the received game user ID and game item information. In the third embodiment, since the exchange server 80 obtains the game user ID of the seller / buyer from the second database 83, the game server 50 does not have a database for associating the trader ID with the game user ID. You don't have to.

In addition, the exchange server 80 is a database that associates the trader ID with the real name information based on the trader ID extracted from the trade information including its exchange ID among the transaction information of the game item blockchain 10 that is effectively approved. Real-name information (name, social security number, account number, etc.) of the seller and the buyer is obtained from the third database 84. The control unit 81 of the exchange server 80 transmits the acquired trader ID and transaction amount information to the financial server 60 and real name information stored in the third database 84.

The control unit 61 of the financial server 60 performs payment processing such as bank transfer on the basis of the real name information and the transaction amount information received from the exchange server 80, thereby completing the game item transaction. In the third embodiment, since the exchange server 80 obtains the real name information of the seller / buyer from the third database 84, the financial server 60 does not have to have a database for associating the trader ID with the real name information. .

Other exchange servers 90 having “game item trading software” can also extract trading information from the game item blockchain 10, but the second and third databases 93 and third databases of other exchange servers 90 Since there is no information for associating the trading user ID with the specific game user ID and the information for associating the trading user ID with the specific real name information (ie, the seller and the buyer have not registered it in advance), such an exchange The server 90 cannot request the owner change and payment processing from the game server 50 and the financial server 60 based on the transaction information. That is, since the exchange servers on the network have a unique database associated with the traders who traded the game items through the corresponding exchange, only the trade information recorded in the game item blockchain including the exchange ID of the game item may be used. Owner change and payment processing are possible.
