Abstract

A node on a blockchain network, includes: a memory that stores asset related data including information on an owner of an asset, and contract related data including a transaction price of the asset or a ratio corresponding to the price of the asset; and circuitry to transmit the asset related data and the contract related data to one or more other nodes on the blockchain network to share the asset related data and the contract related data.

Claims (30)

1 . A system on a blockchain network, the system comprising:

a first node;

a second node; and

a third node, wherein

the first node includes a first memory and first circuitry,

the first memory including a first private area and a first public area, wherein

the first private area is accessible by an entity involved in a specific transaction and having an access right,

the first public area is accessible by any entity,

the first private area stores first contract related data including a transaction price of an asset or a ratio corresponding to the transaction price of the asset, and

the first public area stores power related data including power generation information,

the first circuitry is configured to transmit the power related data and the first contract related data to the second node and the third node on the blockchain network every predetermined time to share the power related data and the first contract related data,

the second node includes a second memory and second circuitry,

the second memory includes a second private area and a second public area,

the second circuitry is configured to

store data related to electric power having been allocated to a consumer by supply-demand balance control in the second public area and second contract related data in the second private area, and

transmit the data related to electric power having been allocated and the second contract related data to the first node and the third node every predetermined time to share the data related to electric power having been allocated and the second contract related data,

the third node includes a third memory and third circuitry,

the third memory includes a third private area and a third public area, and

the third circuitry is configured to

store data related to electric power being consumed in the third public area, and

transmit the data related to electric power being consumed to the first node and the second node every predetermined time to share the data related to electric power being consumed.

2 . The system of claim 1 , wherein an access right to the contract related data is assigned to entities involved in a transaction of the asset.

3 . The system of claim 1 , wherein the power related data includes information indicating a type of a production method of the asset.

4 . The system of claim 3 , wherein the type of the production method indicates that the asset is produced using a predetermined type of resource.

5 . The system of claim 1 , wherein the power related data includes information indicating a transaction status of the asset.

6 . The system of claim 5 , wherein the information indicating the transaction status of the asset indicates one of production of the asset, intermediation of transfer of the asset, and use of the asset.

7 . The system of claim 5 , wherein

the asset is electric power, and

the information indicating the transaction status indicates charging or discharging of the electric power.

8 . The system of claim 1 , wherein the circuitry is further configured to receive data related to electric power having been allocated and the contract related data.
