Description

Blockchain-based renewable energy consumption authentication device

The present invention relates to a blockchain-based renewable energy consumption authentication device. More specifically, consumption data is generated by comprehensively calculating the consumption of multiple renewable energies such as electric energy, thermal energy, or water usage consumed within the building, and the consumption data is stored in a blockchain network to offset renewable energy consumption. It is about a blockchain-based renewable energy consumption certification device that allows the use of new and renewable energy to be recognized and capitalized by generating a certificate.

The whole world is paying attention to carbon neutrality. Carbon neutrality can be seen as an effort to reduce carbon emissions.

There are two main ways to achieve carbon neutrality. The first method is to supply renewable energy with zero or close to zero carbon emissions to individuals or companies.

The second way is to achieve carbon offsets. Carbon offsetting involves reducing greenhouse gases by the amount of carbon dioxide previously emitted, investing in environmental funds, planting trees, or replacing previously consumed energy with new and renewable energy. This means canceling out.

Meanwhile, the government and organizations are providing many incentives to companies or individuals who have achieved carbon neutrality through the above two methods, but appropriate verification and certification methods have not been implemented, and the method was created with a focus on companies rather than individuals, so it is still carbon neutral. This is not widely achieved, and even the effect of carbon neutrality is minimal.

As an example of a specific problem, even if a company struggles to consume new and renewable energy, the process for certifying and verifying the consumption is complicated and expensive, and the renewable energy subject to certification and verification is limited to electrical energy, so electricity Renewable energy other than energy may be marginalized or the opportunity to choose to consume a variety of new and renewable energy may be deprived, and even if certification and verification of new and renewable energy consumption are implemented, there is still no response to security and compatibility. It is not being done properly so far.

The present invention was developed with an eye on this problem, and not only can solve the technical problems discussed above, but also provide additional technical elements that cannot be easily devised by those skilled in the art. It has been done.

For reference, this invention was supported by the following national research and development project.

The present invention relates to a blockchain-based renewable energy consumption authentication device. More specifically, consumption data is generated by comprehensively calculating the consumption of multiple new and renewable energies such as electric energy, thermal energy, hydroelectric energy, and wind energy consumed within the building, and the consumption data is stored in the blockchain network to generate new and renewable energy. This relates to a blockchain-based renewable energy consumption authentication device (hereinafter abbreviated as consumption authentication device 100) that allows the use of new and renewable energy to be recognized and capitalized by generating a consumption offset certificate.

Before looking at this renewable energy consumption certification device 100, let's first look at the renewable energy consumption and the renewable energy consumption offset certificate referred to in the present invention.

[Renewable energy consumption]

As previously explained in the background of the invention, Korea is making a lot of efforts to reduce carbon emissions, and as one of these efforts, it is even introducing a plan to provide incentives to companies that reduce the amount of carbon emissions.

Referring to Figure 1, Korea is measuring the carbon reduction amount of companies in order to implement the above plan, and the following two methods are used to measure the carbon reduction amount.

The first method (A in Figure 1) is a method of calculating the carbon reduction amount by calculating the difference between past carbon emissions and current carbon emissions.

The second method (B in Figure 1) analyzes the factors of the building to be measured (building area, number of residents, average cooling/heating use time, etc.) to calculate standard carbon emissions and adds the current carbon emissions to the standard carbon emissions. This is a method of calculating carbon reduction by subtracting.

However, the conventional carbon reduction calculation methods mentioned above had the inconvenience of having to calculate and analyze the carbon reduction for each building individually, and in particular, a verified national agency must be involved when calculating the standard carbon emissions. Not only does it take a lot of time, but it also costs a lot of money during the calculation process.

In order to solve this problem, the present invention sets the carbon reduction amount to the same value as ‘new and renewable energy consumption’ to calculate the carbon reduction amount more simply.

Referring to Figure 2, when a building uses a mixture of general energy (energy that emits carbon when consumed) and new and renewable energy, the sum of the consumption of general energy and the consumption of new and renewable energy is naturally the 'total energy'. It would be ‘energy consumption’. At this time, while general energy emits carbon when consumed, new and renewable energy does not emit carbon even when consumed, so the 'total carbon emission' of the building is calculated by subtracting the new and renewable energy consumption from the 'total energy consumption'. Likewise, the value obtained by subtracting 'total carbon emissions' from 'total energy consumption' will be the carbon reduction amount, and this value will be the same as 'renewable energy consumption'.

For this reason, the present invention replaces the carbon reduction amount with the same value as the renewable energy consumption amount. In addition, since the 'total energy consumption' of a building is offset by the 'total carbon emissions' as the consumption of new and renewable energy increases, the present invention can be used interchangeably with the expression of reducing carbon emissions as well as the expression of offsetting carbon emissions. I understand that there is.

[Renewable energy consumption offset certificate]

Some countries, including Korea, provide incentives to companies that offset their carbon emissions, but in order for companies to receive the incentives, they must submit evidence that they have offset their carbon emissions to a national agency or organization.

However, some countries, including Korea, are still focusing only on certificates issued by power generation companies that supply electricity, such as the Renewable Energy Certificate (REC), and are not involved in issuance of certificates for the consumption of renewable energy. This is not being done properly. For this reason, the present invention seeks to provide a renewable energy consumption offset certificate (hereinafter abbreviated as consumption offset certificate) that allows the subject issuing the certificate to be an individual or company.

The consumption offset certificate can be used as an indicator of how much an individual or company has contributed to preventing international climate change and environmental conservation by offsetting carbon emissions, and can also be used as a certificate that can provide various benefits and incentives from national agencies or organizations. It can be.

Furthermore, the present invention can maximize the security and scalability of these consumption offset certificates through a blockchain-based network and enable them to be issued as new authentication assets.

Above, we looked at the renewable energy consumption and the renewable energy consumption offset certificate referred to in the present invention.

Next, let's look at the blockchain-based renewable energy consumption authentication device 100 according to the first embodiment of the present invention.

Figure 3 is a schematic diagram showing a blockchain-based renewable energy consumption authentication device 100 according to the first embodiment of the present invention.

[Consumption authentication device (100)]

Referring to FIG. 3, the consumption authentication device 100 generates consumption data by integrating a smart meter 110 that measures renewable energy consumption, a sensing unit 120 that measures ambient temperature, and a plurality of renewable energy consumption amounts. It includes an operation unit 130 that collects the generated consumption data into one protocol, a communication unit 140 that generates a consumption offset certificate based on the consumption data, and a blockchain RTU (150) that generates a consumption offset certificate and stores it in a blockchain network.

[Smart Meter (110)]

First, the smart meter 110 is a terminal-type device that can be installed in a building that consumes at least one new type of energy. At least one new renewable energy mentioned here includes electric energy, hydroelectric energy, wind energy, as well as fuel cells. Includes coal gasification, hydrogen energy, solar heat, solar power generation, biomass, wind power, small hydro, geothermal energy, marine energy, and waste hydro energy.

The smart meter 110 does not stop at measuring just one of the types of renewable energy listed above, but can measure heterogeneous energy comprehensively. At this time, a plurality of smart meters 110 are provided so that each smart meter 110 is responsible for measuring one renewable energy, and a single smart meter 110 can measure a plurality of new and renewable energy in an integrated manner. It may be designed to do so.

The smart meter 110 generates measurement data on the consumption of at least one or more renewable energy. As a specific example, 1) measurement data for electrical energy (kWh) is generated by subtracting the electrical energy consumption received from existing external organizations (e.g. Korea Electric Power Corporation) from new and renewable energy production (solar power production), and 2) thermal energy Measurement data for (kCal) is generated by converting the amount of thermal energy (kCal) from the source supplied through geothermal heat (renewable energy) into kWh. 3) Measurement data for water usage (m ³ ) is generated by converting the unit to kWh. This is data generated by estimating the energy consumption consumed to produce the amount of water consumed by the user among the energy consumption of fuel cells (new and renewable energy) used for this purpose. For example, assuming that a 100 kWh fuel cell is used to produce water in a building, and that this 100 kWh fuel cell consumes 1 kWh of energy to produce 10 L of water, if the user used 10 L of water, the smart The meter 110 generates measurement data for 10L of water usage by estimating 1kWh.

Meanwhile, the external device 200 may refer to devices that can measure the consumption of renewable energy only if they are inevitably located outside the building. For example, an electric vehicle charger located in the parking lot or outside of a building, or a solar inverter located on the exterior wall under the rooftop of a building, measures the amount of new and renewable energy consumption generated while charging an electric vehicle, generates measurement data, and generates measurement data from solar energy. Measurement data can be generated by measuring the amount of renewable energy consumed as it is converted and consumed into electrical energy.

[Sensing unit (120)]

The sensing unit 120 can be understood as a component that detects a fluctuating phenomenon in exchange for consuming energy resources, and may be a sensor that measures ambient temperature, for example. The ambient temperature measured from the sensing unit 120 is not only used when the calculating unit 130, which will be described later, generates consumption data, but can also be used as a value to measure the efficiency of renewable energy (temperature increase/decrease compared to consumption). . For reference, the sensing unit 120 is not limited to sensors that sense the surrounding temperature, but also includes data (temperature, illuminance, air quality) that fluctuates in exchange for consuming energy resources, such as sensors that detect illuminance and sensors that determine air quality. ) can be used as the sensing unit 120 of the present invention.

[Computation unit (130)]

The calculation unit 130 generates consumption data based on the value measured by the sensing unit 120 and at least one measurement data measured by the smart meter 110. For example, consumption data is data that integrates ambient temperature and multiple measurement data. It can also be said to be data in which the carbon offset value is calculated by analyzing the changed ambient temperature and multiple measurement data over a predetermined period of time (e.g., 15 minutes).

The calculation unit 130 can utilize learned AI and big data to analyze a plurality of measurement data. Specifically, the heterogeneous energies included in the measured data may have different carbon offset values compared to the amount consumed, and when the measured data is generated, various factors (heterogeneous energies are measured simultaneously, external temperature Changes may occur due to sudden changes in ambient temperature, etc.), and it is difficult to estimate carbon offset values and generate consumption data using only the obtained measurement data. Therefore, big data containing reference data and various This means that the learned AI can be used together to derive results even if the situation and conditions are different.

For reference, the reason why the carbon offset values for each of the heterogeneous energies included in the measurement data are different compared to the amount consumed is that the amount consumed is itself carbon dioxide for energy that does not emit carbon even when consumed, such as solar energy. This may be an offset value, but since coal gasification energy may emit a small amount of carbon in the same case, it is calculated by considering the amount of carbon emissions.

[Communication Department (140)]

The communication unit 140 is a component designed to facilitate data exchange with device components or external servers (e.g., third-party server 400, ESS server, etc.).

Additionally, the communication unit 140 serves to receive measurement data from the external device 200. Specifically, the smart meter 110 and the calculation unit 130 are components located within the consumption authentication device 100, so the smart meter 110 does not necessarily transmit measurement data to the calculation unit 130, but the two components are interconnected. However, since the external device 200 located outside the building cannot be linked with the calculation unit 130, the external device 200 transmits the measured data to the calculation unit 130. To this end, a communication module (not shown) may be provided to transmit measurement data to the communication unit 140. For reference, if the external device 200 is connected to the consumption authentication device 100 by wire, it can be used in conjunction with the components of the consumption authentication device 1 without the need for the data transmission role of the communication unit 140 described above. there is.

Meanwhile, the communication unit 140 collects the consumption data generated by the calculation unit 130 into one protocol, and the blockchain RTU 150, which will be described later, allows the consumption data to be stored in the blockchain network 300.

[Blockchain RTU(150)]

The blockchain RTU (150) uses the consumption authentication device (100) placed in each household or building as one blockchain node, and multiple blockchain nodes, that is, multiple consumption authentication devices (100), block each other through each other's communication network. It allows building a chain network (300).

When the communication unit 140 collects consumption data into one protocol, the blockchain RTU (150) stores the consumption data in the blockchain network (300). As for the consumption data stored in the blockchain network, a plurality of blockchain nodes, that is, a plurality of consumption authentication devices 100, confirm and verify each other's consumption data to generate a consumption offset certificate.

Meanwhile, the blockchain RTU (150) can generate a consumption offset certificate on its own before the consumption data is stored in the blockchain network (300). Specifically, the blockchain RTU (150) builds a blockchain network (300) by generating a consumption offset certificate based on consumption data collected through the single protocol and storing the renewable energy consumption offset certificate. You can.

On the other hand, the verification server 500, which is linked to the blockchain RTU 150, is additionally included in the system and is used by existing national agencies and organizations before consumption data is stored in the blockchain network 300. A consumption offset certificate can be created through relatively simple authentication and verification compared to the previous authentication and verification. At this time, the authentication and verification performed by the verification server may include verification of whether the consumption data is compatible with the blockchain network 300, verification of errors in the consumption data, and verification of the possibility of manipulation/hacking of the consumption data. .

The consumption offset certificate generated in this way can become a transaction currency itself and can be implemented to enable consumption offset certificate transactions between users on the blockchain network.

In addition, the blockchain RTU (150) can generate a blockchain-type transaction token based on the consumption offset certificate and allows users to transact on the consumption offset certificate with the transaction token. For reference, since the transaction token is implemented in blockchain form, it does not go through an external agency (UN, government agency, or verification agency), allowing consumption offset certificate transactions between users without verification and relay fees, allowing users to offset carbon. Not only does it encourage this, but it also allows another economic market to be formed.

Figure 4 shows the specific components of the blockchain-based renewable energy consumption authentication device 100 according to the first embodiment of the present invention through a schematic diagram.

To explain the roles of the above-described components with reference to FIG. 4, measurement data generated from the smart meter 110 is collected through a protocol called Modus through RS485 communication, and the collected data is implemented in an international web standard XML language called OBIX. and stored in the blockchain network 300. For reference, data exchange with the external device 200 is also performed through TCP/IP or direct RS485 communication, but in the case of a solar inverter, it is collected as a separate SunSpec protocol through TCP/IP communication and used as the OBIX described above. It is implemented and stored in language.

Meanwhile, it is understood that the components of the consumption authentication device 100 shown in FIG. 4 are not limited to the above-mentioned components and the components shown, and that some components may be added or deleted.

Figure 5 is a diagram illustrating a process in which the calculation unit 130 generates consumption data and billing data.

Referring to FIG. 5, the calculation unit 130 receives measurement data from the smart meter 110 and the external device 200, receives data on the surrounding temperature from the sensing unit 120, and combines this measurement data and the surrounding temperature. Based on this, consumption data and billing data are generated by estimating new and renewable energy consumption and expected billing amount (usage fee). Here, the billing data is data estimated by the calculation unit 130 by analyzing the consumption data in predetermined time units and calculating a usage fee for the consumption data.

In this process, the calculation unit 130 can utilize learned AI and big data technology to estimate renewable energy consumption and expected billing amount according to various factors. Specifically, the calculation unit 130 calculates factors such as the type of new and renewable energy consumed, carbon emissions compared to the consumption of new and renewable energy, and carbon emissions offset when using mixed renewable energy, as well as the area of the building, the number of residents, and the energy consumption of residents. Since it may be difficult to calculate consumption data and billing data for various factors such as patterns, it is possible to estimate renewable energy consumption and expected billing amount based on the various factors listed above by utilizing the vast reference data of big data and learned AI. That there is.

Meanwhile, the calculation unit 130 can receive help from the third-party server 400 when estimating the amount of renewable energy consumption and the expected billing amount. Here, the third-party server 400 is a server that predicts and analyzes the price of energy. It not only predicts and analyzes the price of energy that can fluctuate due to weather, climate, temperature, current energy supply, various events/accidents, etc., but also predicts and analyzes the price of energy. Measurement data generated from the meter 110 is analyzed to analyze energy consumption, consumption patterns, etc. to generate third-party data and then transmit it to the communication unit 140 of the present invention. Furthermore, the third-party server 400 can perform the role of recommending energy suitable for consumption in the building, such as the location of the building and the area of the building.

Figure 6 is a schematic diagram showing the process in which the communication unit 140 collects and processes consumption data and billing data generated from the calculation unit 130 into one protocol.

Referring to FIG. 6, the communication unit 140 receives consumption data and billing data generated from the calculation unit 130, collects these two data into one protocol, and thereafter, the communication unit 140 uses one protocol. The collected data is transmitted to the blockchain RTU (150).

Meanwhile, the communication unit 140 can transmit consumption data and billing data to the user terminal 10 so that the user can check the consumption data and billing data in real time. there is.

FIG. 7 is a diagram illustrating a process in which the blockchain RTU 150 receives collected data from the communication unit 140 and transmits the collected data to the blockchain network to generate a consumption offset certificate.

Referring to FIG. 7, the blockchain RTU 150 allows a single consumption authentication device 100 to become one node in the blockchain network 300, and at this time, the consumption data collected from the communication unit 140 causes the blockchain RTU (150) to be stored in the blockchain network 300, and when the consumption data is stored in the blockchain network 300, a plurality of nodes in the blockchain network 300 verify and verify each other's consumption data. Confirm that the consumption data stored in the blockchain network 300 itself becomes a consumption offset certificate (A in Figure 7).

Meanwhile, the consumption offset certificate can be implemented so that the blockchain RTU (150) can generate it itself before the consumption data is stored in the blockchain network (300) (B in FIG. 7).

On the other hand, before the consumption data is stored in the blockchain network 300, the verification server 500 linked to the consumption authentication device 100 can be implemented to verify the consumption data and generate a consumption offset certificate. (C in Figure 7).

The consumption offset certificate generated in this way can be used as a transaction currency on its own, or it can be created as a transaction token in the form of a blockchain by the blockchain RYU (150) to enable transactions between users.

Above, we looked at the blockchain-based renewable energy consumption authentication device 100 according to the first embodiment of the present invention.

Next, let's take a step-by-step look at how to use the blockchain network to certify renewable energy consumption. For reference, the explanation of how to use the blockchain network for renewable energy consumption authentication is the same as the explanation of the roles of the components of the consumption authentication device 100 described above, so detailed step-by-step explanation will be omitted to prevent redundant description. .

Figures 8 to 10 are diagrams specifically showing how the consumption authentication device 100 builds a blockchain network according to the first embodiment of the present invention.

Referring to FIG. 8, in order for the consumption authentication device 100 to build the blockchain network 300, first, it acquires measurement data from the smart meter 110 and the external device 200, and then obtains measurement data from the surrounding area from the sensing unit 120. It starts with the step of acquiring data about temperature (S101).

After step S101, the calculation unit 130 generates consumption data based on measurement data and data on ambient temperature obtained using learned AI and big data (S102).

After step S102, the communication unit 140 collects the generated consumption data into one protocol, and the blockchain RTU 150 stores the consumption data in the blockchain network to generate a consumption offset certificate (S103).

Referring to FIG. 9, after step S102, the blockchain RTU 150 may include a step (S103a-1) of automatically generating a consumption offset certificate based on consumption data collected from the communication unit 130.

After step S103a-1, the blockchain RTU 150 may include a step (S103a-2) of storing the self-generated consumption offset certificate in the blockchain network 300.

Referring to FIG. 10, after step S102, the blockchain RTU 150 may include a step (S103b-1) in which the consumption data collected from the communication unit 130 is verified by the verification server 500.

After step S103b-1, the blockchain RTU 150 receives a consumption offset certificate generated by the verification server 500 verifying the consumption data, and stores the received consumption offset certificate in the blockchain network 300 ( S103b-2) may be included.

After step S103, the blockchain RTU (150) can generate a blockchain-type transaction token based on the consumption offset certificate (S104), and enables consumption offset certificate transactions between users through the generated transaction token.

Above, we looked at how to use the blockchain network to certify renewable energy consumption.

Next, let's look at how to utilize a blockchain network for authenticating renewable energy consumption according to the second embodiment of the present invention.

The second embodiment of the present invention is an embodiment of a method for calculating the user's contribution to the act of consuming renewable energy and discounting the bill to be paid by the user according to the calculated contribution.

The method of utilizing a blockchain network for renewable energy consumption authentication according to the second embodiment of the present invention includes the steps of first, the user terminal 10 transmitting a request to calculate the user's contribution to the consumption authentication device 100 ( Start from S201). Here, the user terminal 10 is a user terminal with a consumption authentication device 100 installed in the user's building, and the user terminal 10 at this time has an interface capable of exchanging data with the blockchain network 300. It can be assumed that the application is already installed.

After step S201, the consumption authentication device 100 retrieves the consumption offset certificate for the previously stored period from the blockchain network 300 (S202). Here, the previously stored period may be a monthly payment period generated by consuming energy, or may be a period arbitrarily set by the user.

After step S202, the consumption authentication device 100 uses the learned AI, big data, and the third-party server 400 to calculate the contribution of the consumption offset certificate viewed in step S201 (S203). For example, if renewable energy was consumed despite the difficulty in supplying new and renewable energy due to disasters, calamities, or other accidents, the contribution weight to reducing carbon emissions can be measured highly, and the government can measure the environmental Even when renewable energy is consumed during a period specifically designated for protection, the contribution to reducing carbon emissions may be given a high weight.

After step S203, the consumption authentication device 100 matches the calculated contribution to the consumption offset certificate for the previously stored period (S204). For reference, the calculated contribution not only matches the consumption offset certificates for the previously stored period, but may also match each consumption offset certificate, allowing the user to check the contribution for one consumption offset certificate.

After step S204, the consumption authentication device 100 transmits the consumption offset certificate with the matching contribution to the billing collection server 600 (S205).

After step S205, the billing collection server 600 calculates a billing discount according to the contribution matched to the certificate (S206) and delivers the calculated billing discount to the user terminal 10 or the blockchain network 300 (S207), The method of utilizing a blockchain network for authentication of renewable energy consumption according to the second embodiment of the present invention is completed.

For reference, it was previously explained that the second embodiment can start from the step where the user terminal 10 transmits a contribution calculation request, but consumption data and consumption offset generated even without the contribution calculation request step (S201) of the user terminal 10. It can be implemented to immediately calculate the contribution to the certificate and match the calculated contribution to the consumption offset certificate.

The second embodiment of the present invention has been described above.

Next, let's look at how to utilize a blockchain network for authentication of renewable energy consumption according to the third embodiment of the present invention.

The third embodiment of the present invention is an embodiment of a method of brokering transactions to enable certificate transactions between user terminals 10 using the blockchain network 300. For reference, in the description of the third embodiment, it will be mentioned that several steps are carried out on the blockchain network 300, but in reality, these steps are performed by one node constituting the blockchain network 300, or a consumption authentication device ( 100), or it is understood that it can be executed by a server device with computing capabilities.

In the third embodiment of the present invention, first, the first user terminal (10A) and the second user terminal (10B) set purchase/sell conditions for consumption offset certificates, and send a purchase/sell request based on the conditions through the blockchain. It starts with the step of transmitting to the network 300 (S301). Here, the first user terminal 10A will be a terminal of a user who wants to purchase a consumption offset certificate, and the second user terminal 10B will be a terminal of a user who wants to sell a consumption offset certificate. In addition, here, the purchase/sale conditions refer to conditions under which the user can satisfy his or her needs through transactions, such as the desired purchase/sell price at which the user wishes to purchase/sell the certificate, contribution level, date on which the certificate was created, etc. For reference, at this time, the consumption authentication device 100 will be installed in the buildings of the first and second users who are the owners of the first user terminal 10A and the second user terminal 10B, and in particular, the second user The consumption authentication device 100 installed in the building will assume that the second user's consumption offset certificate is already stored in the blockchain network 300.

For reference, the consumption offset certificate transaction between these users can be conducted through the transaction token described in the first embodiment above.

After step S301, the blockchain network 300 matches transactions meeting the purchase/sale conditions received from the first user terminal 10A and the second user terminal 10B (S302). At this time, the matched transaction not only matches the purchase conditions and sales conditions that are perfectly matched, but also matches the transaction in which the purchase conditions and sales conditions are closest to each other.

After step S302, the blockchain network 300 calculates the value of the consumption offset certificate subject to the transaction, that is, the consumption offset certificate with which the transaction is matched (S303). Here, the reason for calculating the value of the consumption offset certificate is to prevent users who are making the transaction for the first time from making unfair transactions, in other words, to once again remind them of the fairness of the transaction.

For reference, learned AI and big data can be used to calculate the value of consumption offset certificates. At this time, the current market price, amount of renewable energy supplied at the time of consumption, contribution, etc. can be considered as factors to calculate the value of the consumption offset certificate.

After step S303, the blockchain network 300 settles the transaction when it is confirmed whether the transaction is normal from the first user terminal 10A and the second user terminal 10B (S304).

After step S304, the blockchain network 300 changes the ownership of the consumption offset certificate when the transaction is settled (S304). Specifically, since the first user purchased the consumption offset certificate that was stored as the second user's ownership, it is changed to the first user's ownership.

After step S305, the blockchain network 300 pays the settlement amount (value calculated in step S203) to the sold second user terminal 10B (S306) and certifies renewable energy consumption according to the third embodiment of the present invention. The method of utilizing the blockchain network for this is completed.

We have looked at all embodiments of the blockchain-based renewable energy consumption authentication device above.

The present invention is not limited to the specific embodiments and application examples described above, and various modifications can be made by those skilled in the art without departing from the gist of the invention as claimed in the claims. Of course, these modified implementations should not be understood separately from the technical idea or outlook of the present invention.
