[Solution] The power peg token system consists of nodes 10, which are issued by multiple power suppliers that guarantee the future supply of electricity; nodes 20, which are administrators of power peg tokens backed by these bonds; nodes 30, which are users of power peg tokens; and a platform 40 equipped with a token program, a conversion program, and a clearing program that operate in connection with a ledger that manages transaction records and balances of power peg tokens. The clearing program allows the user's node to send an exchange request between its national legal tender and power peg tokens to the ledger.

Description

Technical Field

[0001] The present invention relates to a power-pegged token system among digital assets (hereinafter referred to as tokens) pegged to electricity. For example, not limited to one country, but in an economic circle consisting of multiple countries (regions) such as the CPTPP (Comprehensive and Progressive Agreement for Trans-Pacific Partnership), it relates to a power-pegged token system that can coexist with the legal currencies of each country.

Background Art

[0002] Virtual currencies such as Bitcoin are said to become a base currency replacing the US dollar, but their usage range is still limited. One of the reasons for this is that there is no collateral for value, resulting in a large fluctuation range.

[0003] To eliminate the large fluctuation range, there are stablecoins pegged to the US dollar, such as DAI, USDT (Tether), USDC (Circle), etc. However, due to being pegged to the US dollar, they only serve as an auxiliary to the US dollar and do not act as a safety valve during a sharp drop in the US dollar.

[0004] The inventor of the present invention proposed pegging to electricity instead of pegging to the US dollar in Patent Document 1. In this Patent Document 1, an exchange that issues value information purchases a power supply guarantee from an operator that retails electricity, such as a power plant, and issues value information corresponding to this power supply guarantee, thus selecting electricity as the backing for the value of the value information. That is, it proposes a model in which future power supply claims are tokenized.

[0005] Furthermore, the inventors have proposed Patent Document 2 as an improved version of the system described in Patent Document 1. Patent Document 2 describes a value information system that includes a server computer owned by an issuing institution that issues value information such as cryptocurrency, and client computers owned by users of the value information, wherein a client-server network model is established between the server computer and the client computers, providing the server with information it holds to the client, and an autonomous distributed P2P (peer to peer) network model is established between the client computers. The server computer receives power supply guarantee information from a power retailer that guarantees to supply power when requested by the client computer for the tax amount or part of the tax, issues value information corresponding to the received power supply guarantee information, transmits the issued value information to the client computer in response to a request from the client computer, and when it receives information from the power retailer that the value information has been used for a power supply request, it deletes or invalidates the power supply guarantee information that underpins the value of the value information, and the client computer receives the value information, transmits the received value information as payment currency to other client terminals, and transmits it to the power retailer as payment currency corresponding to the power used.

[0006] Patent Document 3 proposes a method for managing electricity transactions that is suitable for providing consumers with an environmental value certificate that proves they have transacted with a power generation company that generates electricity using renewable energy. Specifically, the method for managing electricity transactions involves a system in which a transaction management server that stores and manages accounts held by power generators and accounts held by consumers in a distributed ledger on a database, and a certificate issuing server, which are connected to each other via a network, and when a power generator that generates electricity using renewable energy sells electricity to a consumer, the system provides the consumer with an environmental value certificate at the consumer's terminal that proves the consumer is using the power generation means, wherein the transaction management server, based on reverse power flow data received from the power generator's power meter, A method for managing electricity transactions has been proposed, comprising: a grant step of granting a corresponding amount of environmental value tokens to the power generator account; a transfer step of moving the environmental value tokens from the power generator account in the database to the customer account when a transaction is concluded between the power generator and the customer; and an issuance step of issuing the environmental value certificate based on the environmental value tokens moved from the power generator account to the customer account when the certificate issuing server receives an application instruction for the environmental value certificate from the customer's terminal, and transmitting the environmental value certificate to the customer's terminal.

[0007] Patent Document 4 discloses a power trading support system for multiple power generation facilities and multiple consumers, comprising: a supply quantity acquisition unit for each power generation facility that acquires the amount of electricity generated at the power generation facility that has been transmitted to a predetermined power network; a token issuance unit that issues tokens corresponding to the supply quantity to the first account of the power generation facility on the blockchain; a demand quantity acquisition unit for each consumer that acquires the amount of electricity received from the power network; a transmission quantity determination unit that determines the amount of electricity that is deemed to have been sent from the power generation facility to the consumer for each pair of power generation facility and consumer; and a transaction issuance unit that issues a single transaction to the blockchain for each power generation facility, with the first account as the sender and the second account of each of the multiple consumers that make up the pair as the destination, transferring an amount of the token corresponding to the amount of electricity transmitted for each consumer. The transaction issuance unit is implemented by worker devices, and multiple worker devices each issue multiple transactions simultaneously and in parallel.

[0008] Patent Document 5 discloses a power trading management system that manages power plant accounts and consumer accounts using a blockchain network, as a system for managing the contract of consumer usage rights for electricity and the traceability of electricity supply and demand while ensuring authenticity, and comprises: usage right issuance means for issuing usage right tokens for electricity supplied from power plants to power plant accounts; application acquisition means for acquiring application information for the use of supplied electricity from consumers; usage right transfer means for transferring usage right tokens to consumer accounts based on the application information; power generation performance issuance means for issuing power generation performance tokens related to power generation performance to power plant accounts; usage performance acquisition means for acquiring electricity usage performance information from consumers; and power generation performance transfer means for transferring power generation performance tokens to consumer accounts based on the usage performance information and the usage right tokens of the consumer accounts.

[0009] Patent document 6 describes recording the amount of electricity generated from renewable energy sources in a ledger as energy tokens, and issuing, trading, and redeeming them in fixed units such as 1 MWh.

[0010] Patent document 7 discloses a method for tokenizing the amount of electricity generated at a power plant and matching it with consumer usage on a blockchain. [Prior art documents] [Patent Documents]

[0011] [Patent Document 1] Patent No. 6006266 [Patent Document 2] Patent No. 6779454 [Patent Document 3] Patent No. 7225823 [Patent Document 4] Patent No. 7498491 [Patent Document 5] Japanese Patent Publication No. 2025-052768 [Patent Document 6] US2023-0067556A1 [Patent Document 7] WO2017-199053A1 [Overview of the Initiative] [Problems that the invention aims to solve]

[0012] Patent documents 1 and 2 function well when the unit price of electricity remains within a roughly constant range. However, actual electricity prices fluctuate greatly depending on the relationship between supply and demand. Electricity generated at power plants in sparsely populated areas of Hokkaido cannot be transmitted to large electricity consumption areas due to transmission capacity and other reasons. As a result, large regional disparities in electricity unit prices occur, and there are also large differences in unit prices depending on the power generation method, such as hydroelectric, thermal, solar, and wind power.

[0013] Patent documents 3 to 6 describe systems for ensuring the traceability of renewable energy, but they do not disclose anything about the price stability of power peg tokens. Furthermore, while Patent Document 7 tokenizes the amount of electricity generated at a power plant, it does not equalize it, so it cannot be used in a stable manner like StableCoin. [Means for solving the problem]

[0014] To solve the above problems, the power peg token system according to the present invention includes nodes provided by multiple power suppliers, which are issuers of claims that guarantee the future supply of electricity; nodes provided by administrators of power peg tokens backed by such claims; nodes provided by users of power peg tokens; and a platform comprising a token program, a conversion program, and a clearing program that operate in connection with a ledger managing transaction records and balances of the power peg tokens.

[0015] The aforementioned power supply entities include power plants, power companies, and even ordinary households equipped with power generation facilities. The aforementioned administrators are not limited to corporations, but may also include national agencies, companies commissioned by the national government, and local governments, and there may be some overlap between administrators and power supply entities.

[0016] The provision of claims from each power supplier to the administrator may be based on either a request from the power supplier or a request from the administrator.

[0017] "Guaranteeing future power supply" includes users using power peg tokens as payment for their electricity usage. Furthermore, the nodes include various computers, smartphones, and smart cards.

[0018] As the ledger, a distributed ledger and a centrally managed ledger can be considered. As a platform for executing a distributed ledger, the Ethereum blockchain can be cited. The Ethereum blockchain has a conversion smart contract (conversion program), and this conversion smart contract converts into power peg tokens and triggers issuance by a smart contract (token program). In addition to the Ethereum blockchain, smart contract-compatible platforms such as Solana, BNB Smart Chain, Avalanche, and NEAR Protocol can be cited.

[0019] The centrally managed ledger is constructed on a server managed by an administrator (a cloud server or a host computer of a financial institution), and includes a token program, a conversion program, and a clearing program for managing transaction records and balances of the power peg tokens.

[0020] When adopting a centrally managed ledger, it is preferable that the administrator consists of a central bank that issues power peg tokens and a financial institution that conducts management other than the issuance of the issued power peg tokens.

[0021] The node possessed by the administrator executes payment of the consideration of the claim provided from each power supplier to each power supplier, generates a normalization coefficient (k) for making the unit value (unit price) of the power peg tokens equivalent without depending on the power supplier, and transmits a transaction regarding the normalization coefficient (k) to the conversion program (conversion smart contract).

[0022] The conversion program (conversion smart contract) performs a conversion process into power peg tokens by multiplying the power compensated by the claim by the normalization coefficient (k) for each power supplier, and the token program (token contract) issues power peg tokens to the ledger based on the conversion process.

[0023] The settlement program calculates the amount of electricity by dividing the amount of electricity peg tokens received as payment from the user by the leveling coefficient (k) of the power supplier that supplied electricity to the user, and then causes the token program to extinguish the electricity peg tokens corresponding to this amount of electricity. Note that it is the electricity peg tokens that are extinguished in the ledger, not the receivables. The processing of receivables is handled separately. In other words, in this system, claims related to future electricity supply are not recorded in the ledger; only electricity peg tokens issued in accordance with the amount of such claims are recorded in the ledger.

[0024] The aforementioned leveling coefficient (k) is sufficient as long as, regardless of which power supplier the issued power peg tokens are from, that is, even if the unit price of the electricity supplied by each power supplier is different, the unit value becomes equivalent when multiplied by it. Specifically, possible methods include the electricity price of each power supplier divided by the average electricity price of all power suppliers nationwide, the electricity price of each power supplier divided by a specific power supplier, the electricity price of each power supplier, and the moving average of these. However, it is not limited to these methods; any method that eliminates the information about which power supplier the electricity peg tokens on the ledger originate from is acceptable. If the leveling coefficient (k) changes over time, the most recent coefficient shall be adopted.

[0025] Payments from the nodes provided by the aforementioned administrator to the power supply will be made in the form of already circulating power peg tokens, currencies such as yen or dollars, or by offsetting them against taxes payable by the power supply.

[0026] The node provided by the user communicates with the platform (ledger) to request the platform (ledger) to process an exchange between its national legal tender and power peg tokens. Power peg tokens function as a means of payment or clearing, and coexist with fiat currencies. Here, it is preferable that the exchange rate between the domestic legal tender and the power peg token is such that the amount of legal tender or power peg token received by the user's node decreases as a result of the exchange.

[0027] If the tokens are exchangeable for fiat currency, they become subject to arbitrage and are more likely to be used for speculation than as a means of settlement or clearing. To prevent this, the exchange rate between fiat currency and power peg tokens could be set at a rate that causes a decrease in the fiat currency or power peg tokens received by the user (node) through the exchange (a wear rate). [Effects of the Invention]

[0028] According to the present invention, when issuing power peg tokens using a distributed ledger or a centrally managed ledger, the power that backs future power supply compensation claims provided by each power supplier is multiplied by a leveling coefficient that makes the value of each unit power peg token equivalent. This converts the power into power peg tokens without differences in the unit price of electricity, and thus it can be used as a virtual currency or certificate that is not pegged to currencies such as yen or dollars. At the same time, when converting (converting) power peg tokens into electricity value, the conversion is done by dividing by the leveling coefficient of the electrode supplier that supplied the electricity, so no disadvantage arises from the conversion.

[0029] When exchanging electricity peg tokens for fiat currency, setting the exchange rate so that the amount of electricity peg tokens or fiat currency obtained decreases through the exchange can prevent electricity peg tokens from becoming an object of speculation.

[0030] Compared to gold, electricity has superior characteristics as a convertible asset, such as being able to be produced indefinitely despite equipment limitations, being weightless, and being easy to transport (transmit). On the other hand, its only drawback is that the unit price of electricity varies greatly depending on the means of production (hydroelectric, thermal, solar, nuclear, etc.), season, time of day (daytime and nighttime), user (large corporations and ordinary households), and region, making it impossible to realize a token pegged to electricity. However, this invention eliminates the only drawback of electricity.

[0031] Furthermore, even in the event of a sharp decline due to earthquakes, wars, or other events, power-pegged tokens can be used as payment for electricity consumption, thus hedging against a currency price crash. The power-pegged token is originally pegged to electricity, and by multiplying it by a coefficient to link it to currencies such as the yen (or dollar), it becomes an extremely stable token backed by both yen and electricity. In other words, when the yen or dollar is stable, it can be used as a cryptocurrency or certificate, and if the yen or dollar plummets, it can be used to hedge against risk by purchasing electricity.

[0032] This system can be used as a means of settlement (settlement) in economic zones composed of multiple countries (regions), such as the CPTPP. Changing the legal tender circulating in each country to a single currency (such as the euro) is difficult within the CPTPP because it involves national sovereignty and the economic collapse of one country would immediately affect other member states. However, electricity peg tokens can coexist with legal tender and use a single clearing method, making them useful as a regional currency.

[0033] This system is a model where funds are obtained by issuing bonds in advance and then used to supply electricity in the future. Therefore, small-scale power plants can use this as a source of funds for initial investment and equipment upgrades. Furthermore, power generation facilities (especially hydroelectric power plants) built in sparsely populated areas often have excess capacity relative to demand. This system, by issuing power-pegged tokens, aims to correct economic disparities by supplying tokens linked to electricity to the market, even without a physical increase in power supply.

[0034] Because electricity prices vary even within limited regions of a country, this system is effective for issuing local currencies, and it is also possible to set an expiration date (for example, two years from the date of issuance). To encourage the use of power peg tokens, it is possible to set up a system where, for example, if power peg tokens remain unused for a certain period (more than one year), the administrator will charge a management fee based on their usage. Furthermore, smart contracts on the blockchain can be used to restrict token transfers. For example, a whitelist restriction could be implemented that allows transfers only within the same region and between participating merchant wallets. [Brief explanation of the drawing]

[Figure 6] Diagram of the main components of a power peg token system using a centrally managed ledger according to the present invention. [Modes for carrying out the invention]

[0036] Figure 1 shows an example of the power peg token system according to the present invention as a common currency among CPTPP member countries (Countries A to H), and applies a distributed ledger. This system can also be used as a power peg token in conjunction with legal tender within a single country, not limited to the CPTPP.

[0037] As shown in Figure 1, the power peg token system according to the present invention consists of nodes (10) provided by power suppliers in countries F, G, and H, nodes (20) provided by power peg token administrators, nodes (30) provided by power peg token users in countries A, B, C, D, and E, and a platform (40) such as the Ethereum blockchain (distributed ledger). A general-purpose computer can be used as a node and consists of common hardware such as a CPU, ROM, RAM, HDD, BIOS, communication interface unit, input unit such as keyboard and mouse, and display.

[0038] The ledger of Power Peg Tokens (EPT), managed by administrator nodes (20), is built on the Ethereum blockchain (40), which is built on a globally distributed network. Each node on the network holds all or part of the blockchain's data (ledger) and performs verification, propagation, and synchronization of new transactions and blocks.

[0039] User A, who has exchanged (acquired) their local currency for Electricity Peg Tokens (EPT) via the internet, uses the Electricity Peg Tokens (EPT) as a means of transaction (settlement) between other users (nodes) via the internet. Furthermore, when user C uses the Power Peg Token (EPT) not as currency but as payment for their own electricity usage, it is considered that the token has been converted into electricity.

[0040] As shown in Figure 2, the header of each block in the Ethereum blockchain records the hash value of the previous (parent) block, a timestamp, the state root, etc., and the body of each block contains the transaction. Smart contracts are deployed by the creation transaction, and their code and state are held on the world state side.

[0041] The system sequence is explained based on Figure 3. Power suppliers (10) in countries F, G, and H send signals to the administrator node (20) requesting the issuance of bonds that guarantee future power supply. This "guarantee of future power supply" includes the use of power peg tokens as usage fees for power already supplied. Furthermore, if the supply of power peg tokens becomes insufficient or is expected to become insufficient, the administrator node (20) can prompt the power supply node (10) to issue bonds.

[0042] As shown in Figure 3, when an administrator receives a request to issue electricity supply receivables via a node (20), if there are no problems after considering the details of the request, such as whether it is within the range of power generation capacity or the amount of tokens already issued (credit), the administrator sends a transaction to issue electricity peg tokens to the Ethereum blockchain (ledger) on the platform (40).

[0043] When issuing power peg tokens, the administrator will perform a leveling process to ensure that the unit value of all power peg tokens is equivalent, regardless of the origin of the power supplier. The leveling method involves multiplying the power guaranteed by the bonds by a leveling coefficient (k). Possible equalization coefficients (k) include the electricity price of each power supplier divided by the average electricity price of all power suppliers nationwide, the electricity price of each power supplier divided by the electricity price of a specific power supplier, the electricity price of each power supplier, the moving average of these (7 days, 10 days, etc.), or a value determined by the administrator.

[0044] The following example shows a case where the leveling coefficient (k) is calculated as the electricity unit price of each power supplier divided by the average electricity unit price of all power suppliers nationwide. In the case of power supplier F in Japan, if we assume that the amount of electricity (kWh) compensated by the bond is 2.0kWh, the power supplier's electricity price is 10 yen, and the average electricity price of all power suppliers nationwide is 20 yen, then the leveling coefficient (k) becomes 10 / 20 = 0.5, and the power peg tokens to be issued are: 2.0(kWh) x 0.5 = 1.0(EPT) This is the result. Furthermore, in the case of power supplier G, if we assume that the amount of electricity (kWh) compensated by the bond = 1.0kWh, the power supplier's electricity price = 25 yen, and the average electricity price of all power suppliers nationwide = 20 yen, then the leveling coefficient (k) = 25 / 20 = 1.25, and the power peg tokens to be issued are, 1.0 (kWh) x 1.25 = 1.25 (EPT) This is the result. In other words, while the bonds of power supplier F guarantee a greater supply of electricity than those of power supplier G, power supplier G can issue a larger quantity of power peg tokens.

[0045] An example using the electricity unit price of each power supplier as the leveling coefficient (k) is shown below. In the case of power supplier F, if we assume that the amount of electricity (kWh) compensated for by the bond is 2.0kWh and the power supplier's unit price is 10 yen, then the issuance will Power peg tokens are 2.0 (kWh) x 10 (yen) = 20 (EPT) This is the result. Furthermore, in the case of power supplier G, if we assume that the amount of electricity (kWh) compensated for by the bond is 1.0kWh and the power supplier's unit price is 25 yen, then the issuance will Power peg tokens are 1.0 (kWh) x 25 (yen) = 25 (EPT) This is the result. If the unit price of electricity from each power supplier is used as the leveling coefficient (k), it will indirectly be pegged to a circle. For the purpose of explaining using yen, I have used domestic examples as power suppliers, but power suppliers are not limited to domestic entities.

[0046] The value of unit power peg tokens can be made equivalent by using the power unit price of each power supplier / the power unit price of a specific power supplier, their moving average, or a value determined by the administrator as the leveling coefficient (k). Using a value determined by the administrator increases the administrator's flexibility.

[0047] Thus, once a bond is converted into a power peg token, it loses its connection to the bond from which it was issued. As a result, the value of the issued power peg tokens is leveled out, and it becomes possible to merge and subdivide power peg tokens with each other.

[0048] As shown in Figure 4, the administrator node (20) obtains the price per unit of power (power price) for each power supplier from the spot market price (such as JEPX) via an oracle. The administrator node (20) signs the power price, source identifier, timestamp, nonce, etc., and sends the transaction to the transforming smart contract with this signed data as an argument.

[0049] The conversion smart contract determines the amount to be issued based on the issuance request and the electricity price, and sends an issuance command to the token contract. The token contract issues (mints) electricity peg tokens (EPT) based on the command, and the authority to issue is limited to the address of the conversion smart contract.

[0050] To use Power Peg Tokens (EPTs), users must access the administrator's site via the internet from their own node, pay a fee or check their balance, and once approved, the Power Peg Tokens will be sent from the Ethereum network to the user's wallet.

[0051] Furthermore, users can exchange their Power Peg Tokens (EPTs) for their local currency. The exchange rate between the local currency and Power Peg Tokens will be set at a rate (friction rate) where the local currency or Power Peg Tokens received by the user (node) will decrease in value compared to before the exchange. This prevents speculation and allows Power Peg Tokens to function as their intended currency (medium of settlement). The exchange rate can be adjusted by the administrator.

[0052] What distinguishes electricity peg tokens from fiat currency is that they can also be used to exercise their value, meaning that electricity peg tokens (EPTs) can be used as payment for electricity consumption. When electricity peg tokens (EPTs) are paid as consideration for electricity consumption, i.e., when convertibility is executed, the debt is fulfilled, and therefore the electricity peg tokens (EPTs) must be destroyed (burned). In this system, the power peg tokens are extinguished, while the bonds backing these power peg tokens are extinguished through a separate process. It is preferable that the extinguishment of the power peg tokens and the bonds be linked.

[0053] If redemption is executed, as shown in Figure 5, user C's node (30) sends power peg tokens to the Ethereum blockchain's clearing smart contract as payment for the supplied electricity. The clearing smart contract verifies the signed meter reading data received from the meter reading gateway (including contract identifier, measurement period, measured electricity amount, nonce, timestamp, etc.) and matches it against the amount of tokens requested for payment. If the match verification is successful, the clearing smart contract invokes the burnFrom function of the token contract with its own authority to burn the power peg token. This removes the payment token from the ledger and simultaneously records MeterMatched and Burned audit log events. In case of a mismatch or data non-receipt, the transaction is put on hold, and if rematching cannot be completed within the specified time, a refund is processed. Furthermore, the execution authority for the token contract's burnFrom will be limited to the address of the liquidation smart contract only.

[0054] As mentioned above, once a power peg token is issued, it is unknown which power supplier's claims it was converted to. On the other hand, the amount of electricity that can be purchased with 1.0 (EPT) varies by region. For example, when traveling in Hokkaido in an EV, it is possible to exchange it for cheaper electricity peg tokens and use them, so there are also expected benefits in terms of actual demand.

[0055] Thus, when electricity peg tokens are used as payment for electricity, that is, when they are redeemed, the claims issued by the electricity supplier that supplied the electricity used are extinguished. To achieve this, the power peg tokens used are divided by the latest coefficient (k) of the power provider that supplied the power used, converted to power used, and then the power peg tokens corresponding to the power used are burned in the liquidation smart contract. In this way, power peg tokens can be used regardless of which power supplier issued the bond or which power supplier supplied the electricity.

[0056] In the above example, it was assumed that user C would directly send information that they used power peg tokens as payment for electricity usage to the Ethereum blockchain's settlement smart contract. However, in this case, since the administrator has already paid the electricity supplier for the electricity, the administrator could receive the payment (power peg tokens) from the user and then issue instructions to the settlement smart contract from the administrator's node. In other words, the administrator's node could be involved in the process.

[0057] Figure 6 shows an example using a centralized ledger instead of a blockchain. A centralized ledger allows for instantaneous processing and offers security advantages. In the case of a centrally managed ledger, the administrators are divided into the central bank (Bank of Japan) which has the power to issue currency and financial institutions such as banks, and the system is built with nodes owned by the central bank (21) and nodes owned by financial institutions (22).

[0058] Backed by electricity supply claims supplied to the central bank by electricity suppliers, the central bank issues electricity peg tokens by multiplying them by a predetermined coefficient. The issued electricity peg tokens are sent from the financial institution's node (22) to a central management ledger built on a server (cloud server or the financial institution's host computer), and the process thereafter is the same as in the case of the distributed ledger described above.
