Description

NFT-based tracking and carbon trading service system and its control method

[0001] The present invention relates to an NFT-based tracking and carbon trading service system and a control method thereof. More specifically, the present invention relates to an NFT-based tracking and carbon trading service system and a control method thereof, which monitors the amount of electricity and carbon emissions used in electronic devices, records them in NFTs, and obtains carbon emission details by purchasing the NFTs.

[0002] Blockchain is a tamper-proof technology based on distributed computing technology. It stores small data sets called "blocks" in a peer-to-peer (P2P) chain-like structure, linking them together to prevent arbitrary modification and allowing anyone to view the results of any changes. Blockchain is designed to prevent arbitrary manipulation by distributed node operators by recording continuously changing data on a change list across all participating nodes.

[0003] Meanwhile, the world is currently implementing a gradual reduction in carbon emissions, a major cause of global warming, through the Kyoto Protocol. Under the Kyoto Protocol, obligated countries and companies set carbon emissions limits for each period and are required to trade carbon emissions allowances for excess emissions.

[0004] To ensure the stable operation of the carbon emissions cap system and encourage carbon emissions reduction among many people, it is necessary to accurately calculate carbon emissions and reductions by carbon source, make these records tamper-proof and transparently disclosed, and provide fair incentives to those involved in reducing carbon emissions.

[0005] Carbon emissions can be categorized into Scope 1 (direct emissions), Scope 2 (indirect emissions), and Scope 3 (other indirect emissions). Scope 3, in particular, accounts for 70-80% of carbon emissions for most companies, with a significant portion occurring during the product use phase. However, Scope 3 emissions are one of the most difficult areas to track and calculate because they occur outside of a company's direct control.

[0006] Therefore, contributing to achieving carbon neutrality depends on how Scope 3 emissions are addressed, and a reliable carbon emissions tracking system is needed to track and calculate them.

[0007] One embodiment of the present invention seeks to solve the aforementioned problem and proposes a system that provides reliable carbon emission tracking data by tracking the amount of carbon emitted during the use phase of a device product and recording it on a blockchain.

[0008] Another embodiment of the present invention proposes a system that enables a company to acquire a record of a device's carbon emissions by purchasing an NFT in which the device's carbon emissions are recorded in metadata, and to perform carbon offsetting at the corporate level.

[0009] In addition, another embodiment of the present invention provides a system that can analyze a user's usage pattern by recording the carbon emissions of a device on an hourly basis and provide advice on saving electricity usage, thereby motivating carbon reduction.

[0010] The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0011] An NFT-based tracking and carbon trading service system according to one embodiment of the present invention is characterized by including: a step of monitoring electricity usage and carbon emissions in an electronic device; a step of transmitting a first transaction requesting issuance of an NFT linked to the electronic device from a user terminal to a blockchain network; a step of issuing an NFT linked to the electronic device from the blockchain network to a user wallet existing in the user terminal; a step of generating a second transaction for recording history data of the electronic device monitoring the electricity usage and carbon emissions in a block related to the NFT linked to the electronic device; and a step of a carbon trading service server purchasing the NFT and obtaining data related to the carbon emissions.

[0012] The above carbon transaction service server may be characterized by performing carbon offsets for the carbon emissions and providing additional rewards corresponding to the carbon emissions to the user terminal.

[0013] The above carbon transaction service server may be characterized in that it receives history data recorded in a block regarding the NFT from a blockchain network and determines whether to purchase the NFT based on the history data.

[0014] The above carbon transaction service server may be characterized in that it determines the purchase of the NFT in order of the lowest electricity usage of the device from the history data recorded in the block regarding the NFT.

[0015] The carbon transaction service server may be characterized in that it transmits a message requesting consent to data collection to the user terminal, and if a response agreeing to the message is received from the user terminal, it transmits a reward to the user terminal.

[0016] The electronic device may be characterized in that it records the history data monitoring the carbon emissions in a block related to the NFT at a preset power usage data generation cycle.

[0017] The electronic device may be characterized in that the power usage data generation cycle is set differently for each type. In the case of a first type electronic device, the power usage data generation cycle may be set in units of years, in the case of a second type electronic device, the power usage data generation cycle may be set in units of hours, and in the case of a third type electronic device, the power usage data generation cycle may be set in units of minutes.

[0018] The above carbon transaction service server may be characterized by analyzing the history data and providing a power usage reduction guide for the second type electronic device.

[0019] The above carbon transaction service server may be characterized by analyzing the history data and providing a power usage reduction guide and power saving program for the third type electronic device.

[0020] According to another embodiment of the present invention, a method for controlling an NFT-based tracking and carbon trading service system includes the steps of: monitoring electricity usage and carbon emissions in an electronic device; transmitting a first transaction requesting issuance of an NFT linked to the electronic device from a user terminal to a blockchain network; issuing an NFT linked to the electronic device from the blockchain network to a user wallet existing in the user terminal; generating a second transaction for recording history data of the electronic device monitoring the electricity usage and carbon emissions in a block related to the NFT linked to the electronic device; and a step in which a carbon trading service server purchases the NFT and obtains data related to the carbon emissions.

[0021] According to one embodiment of the present invention, by measuring electricity usage and carbon emissions during the device's usage phase and recording the history on a blockchain, transparent and reliable Scope 3 carbon emission tracking data can be provided.

[0022] According to another embodiment of the present invention, a company can contribute to carbon reduction by purchasing carbon emission data resulting from device usage by a trusted consumer recorded in an NFT and performing carbon offset.

[0023] In addition, according to another embodiment of the present invention, by recording the carbon emissions of a device by time unit, the user's usage pattern can be analyzed, and data with lower carbon emissions can be purchased in order to motivate consumers to reduce carbon emissions.

[0024] Further scope of applicability of the present invention will become apparent from the detailed description below.

[0041] In specifically describing the embodiments of the present disclosure, examples of specific systems will be primarily targeted, but the main points claimed in this specification can be applied to other communication systems and services having similar technical backgrounds within a scope that does not significantly exceed the scope disclosed in this specification, and this can be done at the discretion of a person skilled in the relevant technical field.

[0042] Hereinafter, an electronic device using blockchain and a control method thereof according to embodiments of the present invention will be described in detail.

[0043] In this specification, it is assumed that a device refers to an electronic device.

[0044] FIG. 1 is a configuration diagram illustrating the configuration of a carbon tracking and carbon trading service system according to one embodiment of the present invention.

[0045] A carbon tracking and carbon transaction service system (hereinafter, the system of the present invention) according to one embodiment of the present invention is a system that independently creates records of electricity usage and carbon emissions according to the use of the device for each device and stores the records on a blockchain, thereby creating reliable carbon emission data and providing a service that enables the purchase of the same.

[0046] According to one embodiment, the system of the present invention may include a device (100), a user terminal (200), a carbon transaction service server (300), and a blockchain network (400).

[0047] Referring to FIG. 1, a service network to which a device (100), a user terminal (200), and a carbon transaction service server are connected is linked with a blockchain network, thereby transmitting transaction information generated by entities participating in a carbon transaction service to the blockchain network (400), and enabling the processing of transactions to be processed by nodes, which are entities constituting the blockchain network.

[0048] The device (100) may be an electronic device capable of measuring electricity usage. The device (100) may include, for example, a TV, a refrigerator, a washing machine, a laptop, a tablet, a dryer, a dishwasher, a microwave, an air conditioner, a dehumidifier, a vacuum cleaner, a monitor, a styler, a water purifier, and the like. However, the types of devices to which the embodiments of the present invention can be applied are not limited to the examples described above, and the present invention may be applied to various devices that utilize electricity.

[0049] The device (100) may include memory, a monitoring module, a communication unit, and the like. The memory may store applications for providing services to users of the system of the present invention. The monitoring module may monitor the device's electricity usage and carbon emissions and store records. The communication unit may connect to a service network and communicate with user terminals to transmit and receive data or transmit device information, etc.

[0050] Additionally, the device (100) can store an application for accessing a carbon transaction service provided by a carbon transaction service server (300) and a blockchain network (400). The device (100) can access the blockchain network (400) and operate as a node.

[0051] The user terminal (200) is a terminal managed by the entity using the service provided by the system of the present invention. In other words, it is a terminal managed by the actual owner, administrator, or user who purchased and uses the device. The user terminal (200) can store an application for accessing the carbon transaction service provided by the carbon transaction service server (300) and the blockchain network (400). The user terminal (200) can access the blockchain network (400) and operate as a user node.

[0052] The carbon trading service server (300) (hereinafter, "service server") is a device operated by an entity providing carbon trading services. Users utilizing the services of the system of the present invention may include users who have purchased and actually used the device (100).

[0053] The service server (300) can issue an application account (e.g., ID, password, etc.) and a blockchain account (e.g., blockchain wallet, private key, public key, etc.) for using the carbon transaction service to a user using the carbon transaction service, and store information about the issued account.

[0054] The user terminal (200) and the service server (300) may be implemented as various types of devices capable of transmitting and receiving information over a network. For example, they may include portable communication devices, smart phones, computer devices, portable multimedia devices, laptops, tablet PCs, etc. In addition, the user terminal (200) and the service server (300) may be connected to a communication network so as to be operable and transmit and receive information. For example, the communication network may include wired and wireless communication networks such as a local area network (LAN), a wide area network (WAN), a virtual network, and remote communication.

[0055] Figure 2 is a flowchart for explaining a control method of a system according to one embodiment of the present invention.

[0056] Referring to FIG. 2, the device (100) may be in a state of monitoring electricity usage and carbon emissions (S2001).

[0057] Additionally, as described above, the device (100) and the user terminal (200) may store an application for a service according to one embodiment of the present invention. The device (100) may be linked with the user terminal (200) through the application (S2002).

[0058] The carbon transaction service server (300) (hereinafter, "service server") may transmit a message to the user terminal (200) requesting consent to collect data on the device's (100) carbon emissions history for future NFT purchases (S2003). If the user consents to data collection in response to the message, the user terminal may transmit a response indicating consent to the service server (300). In this case, the service server (300) may also provide a reward to the user terminal (200) that consented.

[0059] The device (100) can transmit device information to a user terminal via a communication unit (S2005). At this time, the device information may include information that can uniquely identify the device.

[0060] The user terminal (200) can receive device information from the device (100), generate a transaction requesting the issuance of an NFT, and transmit the transaction to the blockchain network. At this time, the user terminal (200) can also transmit device information to generate a transaction requesting the issuance of an NFT linked to the device (100) (S2006).

[0061] In a blockchain network (400), a smart contract is created, and according to the rules set forth in the smart contract, an NFT linked to the device (100) can be issued to a user wallet existing in the user terminal (S2007). At this time, the NFT linked to the device can be issued for each device (100), and a device can be linked to one or more NFTs. Accordingly, the user terminal (200) can own multiple NFTs for each device. For example, a single wallet can simultaneously contain an NFT linked to a refrigerator, an NFT linked to a TV, and an NFT linked to a washing machine.

[0062] A smart contract is a set of executable software instructions stored and executed by a blockchain network. Smart contracts are typically stored unencrypted and are therefore visible to all participants in the blockchain network. Participants in a blockchain network can create and publish their own smart contracts, and can also typically invoke smart contracts already deployed on the blockchain network. Because the set of instructions available for smart contracts is typically Turing complete, smart contracts can support complex logic to support a variety of business scenarios.

[0063] The device (100) can monitor electricity usage and carbon emissions and record the history in a block related to the NFT associated with the device (100) (S2008). In this way, storing information related to the NFT in a block can enhance the reliability and usability of the NFT. Furthermore, owners and related parties can easily access additional information about the NFT. Utilizing this metadata, NFTs can store and share various information about each unique digital asset on the blockchain.

[0064] The carbon transaction service server (300) can access the blockchain network and search for NFTs. At this time, a blockchain browser may be used. The carbon transaction service server may receive and store data regarding the address or identifier of the NFT linked to the device from the user terminal (200) through the data collection consent (S2004). The service server (300) can search for metadata using the NFT address or identifier for one or more NFTs for which consent has been received. In other words, the service server (300) can request the blockchain network for history data stored in a block related to the NFT (S2009).

[0065] The service server (300) can receive requested history data from the blockchain network (S2010). At this time, the service server can query the history data for all NFTs associated with the agreed-upon devices and determine the NFT purchase according to preset rules. This will be described in detail later in FIG. 7.

[0066] The service server (300) determines the NFT to purchase and can create a transaction to purchase the NFT (S2011). Once the purchase is completed, ownership of the NFT is transferred and can be transferred from the user wallet on the user terminal to the service server (S2012).

[0067] After that, the service server (300) can perform carbon offset for the carbon emission history stored in the purchased NFT (S2013).

[0068] FIG. 3 illustrates an example of recording carbon emissions in an NFT associated with a device in a system according to one embodiment of the present invention.

[0069] As described above in FIG. 2, the device (100) and the user terminal (200) can be linked through an application. FIG. 3 illustrates an example of carbon emission history data that can be checked using the application on the user terminal (200).

[0070] First, the user terminal (200) may receive a message requesting consent for data collection from the carbon trading service server. At this time, consent may be given to the collection of power consumption and carbon emissions data for the linked device (100) (S3001). The device (100) may be, for example, a TV, refrigerator, or washing machine.

[0071] Users can check the NFT issuance status of linked devices via an application stored on their user terminal (200) (S3002). Multiple devices can be linked to a single user terminal (200), and linked NFTs can be issued for each device.

[0072] The user terminal (200) can select and check the NFT associated with each device through the application (S3003). Metadata related to each NFT can also be retrieved through the application. The user can select the device for which they wish to check the carbon emissions and check the power usage history and carbon emissions history stored in the NFT associated with the device (S3004). At this time, the carbon emissions of the device can be monitored on the device and stored in the block of the associated NFT, or can be calculated and calculated in the application. Below, examples of historical data recorded in the NFT for each device will be described.

[0073] Figures 4 to 6 illustrate examples according to device type in a system according to one embodiment of the present invention.

[0074] Figure 4 illustrates an example of a first type device in a system according to one embodiment of the present invention. The first type device may be an electronic device that is in constant use, such as a refrigerator.

[0075] As described above in FIG. 3, the user terminal (200) can be linked with the device (100) through an application and manage the device. In addition, the user terminal (200) can be linked with the device through the application and collect power usage data of the device (S4001).

[0076] Users can consent to the service server's data collection via their user terminal and decide to issue NFTs for Type 1 devices. At this time, the NFT issuance cycle and power record generation cycle can be selected. For Type 1 devices, hourly power usage remains constant and carbon emissions are similar, so the power record generation cycle can be set to daily. Additionally, the issuance cycle can be set to annual (S4002).

[0077] Afterwards, an NFT linked to the first device can be issued by transmitting a transaction requesting the above information and NFT issuance from the user terminal (200) to the blockchain network (S4003).

[0078] Thereafter, the Type 1 device can store power usage in the metadata of the associated NFT. The user terminal can query the metadata using an application (S4004).

[0079] FIG. 5 illustrates an example of a second type device in a system according to one embodiment of the present invention.

[0080] A second type of device may be an electronic device that is used intermittently but requires a constant amount of power, such as a washing machine.

[0081] As described above in FIG. 3, the user terminal (200) can be linked with the device (100) through an application and manage the device. In addition, the user terminal (200) can be linked with the device through the application and collect power usage data of the device (S5001).

[0082] Users can consent to the service server's data collection via their user terminal and decide to issue NFTs for the first device. At this time, the NFT issuance cycle and power record generation cycle can be selected. For Type 2 devices, power usage occurs intermittently, so the power record generation cycle can be set to an hourly basis. Additionally, the issuance cycle can be set to a monthly or yearly basis (S5002).

[0083] Previously, Type 2 devices, which used electricity intermittently, faced the inconvenience of making it difficult to track carbon emissions during product use. According to one embodiment of the present invention, Type 2 devices can also be used by storing usage time in hourly units, thereby verifying carbon emissions corresponding to actual usage time.

[0084] Furthermore, by accurately measuring power consumption on an hourly basis, services that consider hourly carbon emissions can be provided. According to one embodiment of the present invention, the service server (300) can query and analyze the power consumption history recorded in the NFT associated with the device over time. Based on the analysis results, the service server (300) can request power reduction for the device or provide power saving guidance.

[0085] For example, in the case of a Type 2 device, the device can be configured to run a power-saving mode in conjunction with a power-saving program. More specifically, in the case of a Type 2 device such as a washing machine, the full-wash mode can be recommended in conjunction with the power-saving program.

[0086] Additionally, as described below, the service server (300) can provide rewards in the order in which purchases are made, based on the lowest power consumption, and thus contribute to reducing carbon emissions. Accordingly, incentives for reducing power consumption of devices can be provided.

[0087] Afterwards, an NFT linked to a second type device can be issued by transmitting a transaction requesting the above information and NFT issuance from the user terminal (200) to the blockchain network (S5003).

[0088] Thereafter, the second type device can store power usage in the metadata of the associated NFT. The user terminal can query the metadata using an application (S5004).

[0089] FIG. 6 illustrates an example of a third type device in a system according to one embodiment of the present invention.

[0090] A third type of device may be an electronic device that is used intermittently, such as a TV, but whose power usage can be controlled.

[0091] As described above in FIG. 3, the user terminal (200) can be linked with the device (100) through an application and manage the device. In addition, the user terminal (200) can be linked with the device through the application and collect power usage data of the device (S6001).

[0092] Users can consent to the service server's data collection via their user terminal and decide to issue NFTs for Type 3 devices. At this time, the NFT issuance cycle and power record generation cycle can be selected (S6002). Since Type 3 devices experience intermittent power usage, the power record generation cycle can be set to hours or minutes. Additionally, the issuance cycle can be set to months or years.

[0093] Previously, Type 3 devices, which used electricity intermittently, faced the inconvenience of making it difficult to track carbon emissions during product use. According to one embodiment of the present invention, Type 3 devices can also be used by storing usage time in hourly units, thereby verifying carbon emissions corresponding to actual usage time.

[0094] Furthermore, by accurately measuring power consumption on an hourly basis, services that consider hourly carbon emissions can be provided. According to one embodiment of the present invention, the service server (300) can query and analyze the power consumption history recorded in the NFT associated with the device over time. Based on the analysis results, the service server (300) can request power reduction for the device or provide power saving guidance.

[0095] For example, in the case of a Type 3 device, it can be linked to a power-saving program and enabled to enter power-saving mode. More specifically, if the Type 3 device is a TV, it can be linked to a power-saving program and recommended to enter power-saving mode, lower the screen brightness, or recommend a time zone when electricity is cheap.

[0096] Additionally, as described below, the service server (300) can provide rewards in the order in which purchases are made, based on the lowest power consumption, and thus contribute to reducing carbon emissions. Accordingly, incentives for reducing power consumption of devices can be provided.

[0097] Afterwards, an NFT linked to a third type device can be issued by transmitting a transaction requesting the above information and NFT issuance from the user terminal (200) to the blockchain network (S6003).

[0098] Thereafter, the third type device can store power usage in the metadata of the associated NFT. The user terminal can query the metadata using an application (S6004).

[0099] Figure 7 is a flowchart illustrating a carbon trading process of a system according to one embodiment of the present invention.

[0100] As described above, the carbon trading service server can retrieve information from the blockchain network and query the power usage of each NFT. Below, the process of retrieving and purchasing NFT information and offsetting carbon emissions through the application provided by the carbon trading service server is described.

[0101] The entity managing the carbon trading service server can first select the type of electrical device to be queried (S7001). For example, if a refrigerator is selected as the device type, a list of NFTs associated with the refrigerator can be queried. Each NFT can then be selected from the list to view the power usage for each NFT (S7002).

[0102] Additionally, the list of NFTs for selected appliances can be sorted by power consumption (S7003). Afterwards, NFTs for purchase can be selected through the carbon trading service server (S7004). At this time, NFTs can also be selected by power consumption.

[0103] Afterwards, you can purchase the selected NFT and offset the electricity usage recorded on it (S7005). The carbon offset process is explained below.

[0104] For example, a company can measure and evaluate its own carbon emissions. This can be done by considering Scope 1, Scope 2, and Scope 3 emissions, as described above. The company can then implement offset projects for the measured emissions. Examples include planting forests, supporting sustainable energy projects, and improving waste management. When a company implements carbon offsets, an independent certification body can verify that the project has reduced or eliminated carbon emissions. Companies can purchase or exchange certified carbon offset rights on industrial and financial markets. Therefore, companies can purchase carbon offset certificates and offset their carbon emissions within the total amount purchased.

[0105] In one embodiment of the present invention, when the subject wishes to perform carbon offsetting by purchasing a carbon offset certificate, reliable information can be provided using NFT regarding the amount of carbon issued in Scope 3, which is difficult to measure.

[0106] Since the power usage recorded in the NFT purchased by the above entity is reliable data, if carbon offset is performed on this, it can be recognized as the carbon reduction performance of the above entity.

[0107] It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

[0108] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
