Description

Technical Field

[0001] The present invention relates to a power-pegged token system among digital assets (hereinafter referred to as tokens), and more particularly to a hybrid power-pegged token system that combines a distributed ledger and a central management ledger (central management system).

Background Art

[0002] Virtual currencies such as Bitcoin are said to become a base currency replacing the dollar, but their usage range is still limited. One of the reasons 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 dollar, such as DAI, USDT (Tether), and USDC (Circle). However, due to the dollar peg, they only serve as an auxiliary to the dollar and do not act as a safety valve during a sharp drop in the dollar.

[0004] Instead of pegging to the dollar as described above, the inventor of the present invention proposed pegging to electricity 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, thereby selecting electricity as the backing for the value of the value information. That is, a model that tokenizes future power supply claims is proposed.

[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 comprises nodes provided by multiple power suppliers, which are issuers of claims that guarantee the future supply of electricity; a server provided by the administrator of the power peg tokens backed by the claims; nodes provided by users of the power peg tokens; a distributed ledger built on a blockchain that manages transaction records of the power peg tokens and balances calculated based on those transaction records; and a centralized management system built on the server that transmits transactions that execute smart contracts on the distributed ledger and manages user accounts.

[0015] The aforementioned power supply entities include power plants, power companies, ordinary households equipped with power generation facilities, and power aggregators. 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] Examples of the platform for executing the decentralized ledger include the Ethereum blockchain. The decentralized ledger built on the blockchain manages the transaction records of power peg tokens and the balances calculated based on the transaction records. In addition to the Ethereum blockchain, there are also smart contract-compatible platforms such as Solana, Avalanche, BNB Smart Chain, and NEAR Protocol.

[0019] The centralized ledger is built on a server (cloud server or host computer of a financial institution) managed by an administrator and includes a token program, a conversion program, and a settlement program that hold information corresponding to the balances recorded in the blockchain ledger.

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

[0021] The server of the administrator executes the payment of the consideration of the claim provided by each power supplier to each power supplier, generates a normalization coefficient (k) to make the unit value (unit price) of the power peg token 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) multiplies the power compensated by the claim by the normalization coefficient (k) for each power supplier and converts it into power peg tokens, and the token program (token contract) issues power peg tokens to the decentralized ledger based on the conversion process.

[0023] The settlement program calculates the amount of electricity by dividing the amount of power 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 power peg tokens corresponding to this amount of electricity. Note that in the distributed ledger, it is the power peg tokens that are extinguished, not the claims. The processing of claims is handled separately. In other words, in this system, claims related to future electricity supply are not recorded on the distributed ledger; only electricity peg tokens issued in accordance with the amount of such claims are recorded on 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 (absorbs) the origin of the electricity peg tokens on the ledger from which power supplier they belong is acceptable. If the leveling coefficient (k) changes over time, the most recent coefficient shall be adopted.

[0025] Payments from the server maintained by the aforementioned administrator to the power supplier are 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 supplier.

[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, the user interface that users directly see is an account on a centrally managed ledger, while transaction records are kept on a distributed ledger, making it easy to use power peg tokens as local currency.

[0029] Furthermore, by multiplying the electricity backing future electricity supply compensation claims provided by each power supplier by a leveling coefficient that ensures the value of each unit of electricity peg token is equivalent, it is converted into electricity peg tokens with no price difference per unit of electricity. As a result, it can be used as a cryptocurrency or certificate that is not pegged to currencies such as the yen or the dollar. 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 power supply entity that provided the electricity, so no disadvantage arises from the conversion.

[0030] Unlike gold, electricity can be produced indefinitely, albeit with some equipment limitations, and is consumed once used. Things that can be produced indefinitely and are not consumed do not possess a fixed value. It can be produced in unlimited quantities and maintains a certain value because it is consumed upon use, making it an excellent material for exchange.

[0031] On the other hand, the only drawback of electricity is that the unit price 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.

[0032] Furthermore, even in the event of a sharp decline due to earthquakes or wars, power-pegged tokens can be used as payment for electricity consumption, thus hedging against a collapse in the currency's value. In particular, while the value of ordinary currencies gradually decreases due to inflation, power-pegged tokens, which are linked to electricity, a consumer good, do not decrease in value due to inflation.

[0033] 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.

[0034] 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.

[0035] 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 administrators charge a management fee for power peg tokens that have not been used for a certain period (more than one year) when they are used. Furthermore, when power peg tokens are used as payment for electricity consumption, discount services or point rewards that are advantageous to users can be offered to encourage their use. 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] Block diagram explaining the disappearance of the common power peg token. [Modes for carrying out the invention]

[0037] Figure 1 shows an example of the power peg token system according to the present invention as a common currency within a region, and it applies a distributed ledger.

[0038] As shown in Figure 1, the power peg token system according to the present invention consists of nodes (10) provided by multiple power suppliers, a server (20) provided by the power peg token administrator, nodes (30) owned by power peg token users A to E, and a platform such as the Ethereum blockchain (distributed ledger 40). 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.

[0039] The ledger of Power Peg Tokens (EPTs), managed by the administrator's server (20), is built on the Ethereum blockchain (distributed ledger 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.

[0040] User A, who has exchanged (acquired) their local currency for Electricity Peg Tokens (EPT) via the internet, uses Electricity Peg Tokens (EPT) as currency (a means of settlement) with 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.

[0041] 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.

[0042] As shown in Figure 3, the power peg token system according to the present invention is a hybrid of a distributed ledger and a centrally managed ledger operated by an administrator's server. The administrator's server 20 (centralized ledger) manages users' accounts and serves as the user interface (UI) for users. The administrator's server acts as an intermediary between the distributed ledger and the users, and by downloading a dedicated application to the user's node 10, it communicates with the administrator's server 20 to check account balances and perform transfer operations.

[0043] Various power suppliers and power aggregators have mechanisms to balance power supply and demand by adjusting power demand (electricity usage) (DR: Demand Response) and mechanisms to control multiple distributed power sources and demand facilities as if they were a single power plant (VPP) (Virtual Power Plant). These power suppliers (10) send power supply receivables to the administrator's server (20). The administrator then receives payment equivalent to the power supply receivables from the power supplier (10).

[0044] The system sequence is explained based on Figure 4. The power supplier (10) sends a signal to the administrator's server (20) requesting the issuance of a claim that guarantees future power supply. This "guarantee of future power supply" includes the use of power peg tokens as payment 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.

[0045] As shown in Figure 4, 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 the platform's Ethereum blockchain (distributed ledger 40) to issue electricity peg tokens.

[0046] 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 (values ​​excluding the currency unit), the moving average of these (7 days, 10 days, etc.), or any value determined by the administrator that allows for equalization.

[0047] 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 electricity price per unit for power supplier F is 10 yen, and the average electricity price per unit for power suppliers nationwide is 20 yen, then the leveling coefficient (k) for power supplier F is 10 / 20 = 0.5, and the power peg tokens issued will be: 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 electricity price per unit for power supplier G = 25 yen, and the average electricity price per unit for power suppliers nationwide = 20 yen, then the leveling coefficient (k) for power supplier G = 25 / 20 = 1.25, and the power peg tokens issued will be: 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.

[0048] An example using the electricity unit price (excluding the yen unit) 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 unit price of electricity for power supplier F is 10 yen, then the issuance will Power peg tokens are 2.0 (kWh) x 10 = 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 unit price of electricity for power supplier G is 25 yen, then the issuance will Power peg tokens are 1.0 (kWh) x 25 = 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.

[0049] 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 values, or a value that can be leveled as determined by the administrator as the leveling coefficient (k). Using a value determined by the administrator increases the administrator's flexibility.

[0050] If the leveling coefficient (k) is calculated as the electricity price of each power supplier divided by the electricity price of all power suppliers nationwide, the electricity price of each power supplier divided by the electricity price of a specific power supplier, or a moving average of these, the relative value of the electricity prices of each power supplier at the time of leveling will not change significantly, even if electricity rates change between daytime and nighttime within a single day, or if electricity rates change due to seasonal factors, etc. However, if electricity prices fluctuate drastically depending on the specific power generation method or region, it is possible for the administrator to adjust the value of the leveling coefficient (k) to ensure that power suppliers are not unfairly favored or disadvantaged.

[0051] 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.

[0052] As shown in Figure 5, the administrator's server (20) obtains the price per unit of power (electricity price) for each power supplier from the spot market price (such as JEPX) via an oracle. The administrator node (20) signs the electricity price, source identifier, timestamp, nonce, etc., and sends the transaction to the transforming smart contract with this signed data as an argument.

[0053] 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.

[0054] To use Power Peg Tokens (EPTs), users 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 are sent from the Ethereum network to the user's wallet.

[0055] Furthermore, users can exchange their Power Peg Tokens (EPTs) for their local currency (fiat 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 be worth less than the amount received 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.

[0056] What distinguishes electricity peg tokens from fiat currency is that they can also be used to exercise their debt, 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 synchronized.

[0057] If redemption is executed, as shown in Figure 6, 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 with 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.

[0058] 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.

[0059] 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.

[0060] 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. [Explanation of Symbols]
