Description

STGOLD issuance method and device according to the staking and collateral ratio of token securities

[0001] The present invention relates to a method and device for issuing stGold according to the staking and collateral ratio of token securities, and more particularly, to a method and device for issuing stGold according to the staking and collateral ratio (C-Ratio) of SPDR-based token securities tGold.

[0002] Real asset tokenization (RWA) and security token offerings (STOs) are emerging as innovative changes in the financial landscape that can bridge the gap between traditional finance and blockchain technology. Gold, with its abundant liquidity and safe investment vehicle, is the ideal asset for RWA.

[0003] Blockchain is a distributed data storage technology that stores data in blocks, links them together in a chain, and replicates and stores them simultaneously across numerous computers. Blockchain represents a digital ledger where transaction details between users are shared and stored among network members. Rather than storing transaction records on a centralized server, it transmits transaction details to all participating users. For each transaction, all participants share and verify information, preventing data falsification or alteration.

[0004] Accordingly, research is actively underway in industries that deal with transactions between users, such as online commerce and financial services, to safely store transaction history using blockchain technology.

[0005] Typically, blockchain systems manage assets in the form of tokens generated through smart contracts. Tokens can be categorized as fungible tokens (Fungible Tokens), which can be exchanged for other tokens of the same type, and non-fungible tokens (NFTs), which have a unique ID and cannot be exchanged for other tokens. Because NFTs are unique in that they cannot be exchanged for other tokens, they can be used as a means of securely securing ownership of specific assets.

[0006] However, existing blockchain gold tokenization technologies have focused only on the Proof of Reserve for gold to ensure the reliability of gold storage, a physical asset.

[0007] Accordingly, there is a need to propose a technology that addresses the problems inherent in existing blockchain gold tokenization technologies and enables the tokenization of real-world assets such as gold-backed securities and the profit-based assetization of gold token securities.

[0008] The purpose of the present invention is to issue stGold according to the staking and collateral ratio (C-Ratio) of SPDR-based token securities tGold.

[0009] However, the technical problems to be solved by the present invention are not limited to the above problems, and can be expanded in various ways without departing from the technical spirit and scope of the present invention.

[0010] A method for issuing stGold gold tokens according to staking and collateralization ratio of token securities of a computer device including at least one processor according to an embodiment of the present invention, the method comprising the steps of collecting and storing gold ETFs using real assets as collateral, generating tGold, a gold token, by tokenizing the gold ETF into a security, staking the tGold at a preset collateralization ratio to issue stGold, a staked gold token, and bridging the stGold from the blockchain on which the tGold is issued to a heterogeneous mainnet chain.

[0011] A computer device comprising at least one processor implemented to execute computer-readable instructions according to an embodiment of the present invention, the computer device comprising: a management unit for collecting and storing gold ETFs using real assets as collateral, a generation unit for generating tGold, a gold token, by tokenizing the gold ETF into a security, an issuance unit for issuing stGold, a staked gold token, by staking the tGold at a preset collateral ratio, and a processing unit for bridging the stGold from the blockchain on which the tGold was issued to a heterogeneous mainnet chain.

[0012] A computer device comprising at least one processor configured to execute computer-readable instructions according to another embodiment of the present invention, wherein the computer device comprises a collateral tokenization unit that generates tGold by tokenizing a gold EFT collateralized by a real asset and issues stGold by staking the tGold at a preset collateral ratio, and a revenue capitalization unit that capitalizes transaction fee revenue by using a smart contract AMM model for exchange transactions of similar assets, by the at least one processor.

[0013] According to an embodiment of the present invention, by staking tGold, a token security based on SPDR, and issuing stGold based on the collateralization ratio (C-Ratio), it is possible to provide arbitrage opportunities for price differences between markets caused by various factors such as exchange rates, operating hours, and market liquidity. stGold is traded across borders, unaffected by exchange rates, and liquidity and price differences in each market converge to an equilibrium price through arbitrage.

[0014] According to an embodiment of the present invention, the technical effects of tokenizing gold securities, integrating the global gold market, and financializing gold can be achieved.

[0015] However, the effects of the present invention are not limited to the above effects, and can be expanded in various ways without departing from the technical spirit and scope of the present invention.

[0024] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided solely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined solely by the scope of the claims.

[0025] The terminology used herein is for the purpose of describing embodiments and is not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise. As used herein, the terms "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components, steps, operations, and / or elements.

[0026] Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in their common sense to those of ordinary skill in the art to which the present invention pertains. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0027] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings. Identical components in the drawings are designated by the same reference numerals, and redundant descriptions of identical components are omitted.

[0028]

[0029] The present invention is based on the tokenization of gold ETF collateral and the assetization of gold.

[0030] As a result, the present invention can achieve the technological benefits of tokenizing gold securities, integrating the global gold market, and financializing gold. Furthermore, the present invention can create a revenue model by collecting transaction fees for supporting the trading of gold tokens among multiple users. The real asset in the present invention refers to gold.

[0031] Tokenization of Gold Securities - Institutionalized physical gold-backed securities, or gold ETFs, have been operating reliably for decades, with proven ownership or value tracking of physical gold in the institutional system. Unlike gold ETFs, tokenization of physical gold-backed securities and ETFs offers: 1) global market scalability, as traders can send tokens to anyone with a blockchain address globally within minutes or seconds; 2) infinite divisibility and smart contracts enable the creation of diverse DeFi financial products; and 3) seamless, borderless connectivity, as the same international gold price is reflected in each security.

[0032] Global Gold Market Integration - Tokenization of physical gold-backed securities or ETFs around the world will create a gold market that can be traded anywhere in the world 24 hours a day through 1) unification of trading units (fungible goods), 2) bankruptcy remoteness unrelated to the bankruptcy of the issuing company, and 3) real-time payment settlement through a DLT (Digital Ledger Technology) distributed ledger.

[0033] Financialization of Gold - Historically, gold has served as a store of value, providing no expected returns other than holding income and price appreciation. However, this invention provides a DeFi service where investors can earn risk-free returns simply by providing liquidity on a decentralized exchange (Exchange) that supports trading of all real-world assets, including gold-backed tokens, on the blockchain. Furthermore, for investor convenience, this invention tokenizes the liquidity provision LP tokens into Iron Gold (I-Earn GOLD), providing a service where investors (or users) can generate various returns simply by purchasing and holding gold tokens.

[0034] Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 8.

[0035]

[0036] FIG. 1 illustrates a configuration of a platform system in which an underwriter, a platform server, investors, and a third-party custodian participate according to an embodiment of the present invention. FIG. 2 is a block diagram illustrating an example of the basic configuration of a platform server included in a platform system according to an embodiment of the present invention. In addition, FIG. 3 is a block diagram illustrating a detailed configuration of a platform server according to an embodiment of the present invention, and FIG. 4 is a schematic diagram illustrating a process of issuing stGold according to the staking and collateral ratio (C-Ratio) of SPDR-based token securities tGold according to an embodiment of the present invention. In addition, FIG. 5 illustrates an example of a token swap pool according to another embodiment of the present invention, and FIG. 6 illustrates a liquidity provision (LP) of a token swap pool according to another embodiment of the present invention.

[0037] The platform system (100) for issuing stGold based on the staking and collateralization ratio (C-Ratio) of SPDR-based token securities tGold according to an embodiment of the present invention comprises an underwriting group (110), a platform server (120), investors (130), and a third-party custodian (140). At least one investor (130) can access the platform server (120) using a terminal they possess, and can receive services necessary for issuing and returning gold tokens through the platform server (120).

[0038] A platform system (100) for issuing stGold according to the staking and collateralization ratio (C-Ratio) of SPDR-based token securities tGold according to an embodiment of the present invention presents a two-way platform that includes not only the issuance of gold-based tokens as a real asset but also the return procedure of real collateral, and users (or investors) can easily utilize the gold token securities market and the existing gold securities market. In addition, in the platform system (100) for issuing stGold according to the staking and collateralization ratio (C-Ratio) of SPDR-based token securities tGold according to an embodiment of the present invention, the on / off chain of the gold token can integrate the global gold market by forming prices through market functions through arbitrage by investors regarding price differences by country between gold securities (WEB2 market) and gold tokens (WEB3 market), price differences by hour, and price differences between the gold token market and the gold securities market.

[0039] The acquisition group (110) can perform the role of purchasing a certain amount of gold ETF from a company (SPDR) that directly holds real assets and providing it to the platform server (120) as a gold ETF listed on exchanges in the United States, Japan, Singapore, Hong Kong, and Mexico.

[0040] An investor (or user, 130) can access the platform server (120) using a terminal, log in by entering an ID and password through KYC identity verification, and open and register a securities account and wallet when registering identity verification. Accordingly, the investor (130) can deposit a gold token subscription fee for issuing gold tokens through the terminal, and can also request a gold token return to receive gold securities in return for the gold tokens. Here, the terminal may typically be a smartphone, a mobile phone, a laptop, a tablet computing device, etc. The terminal carried by the investor is a portable wireless terminal capable of wireless communication, and is equipped with an application for a platform that issues stGold according to the staking of SPDR-based token securities tGold and the collateral ratio (C-Ratio) according to an embodiment of the present invention.

[0041] A third-party custodian (140) generates gold tokens equivalent to the gold securities, using the gold securities as collateral, burns the gold tokens in the amount included in the gold token burn request, and simultaneously withdraws and provides gold securities equivalent to the amount of the gold tokens being burned. The third-party custodian (140) may be an investment management institution such as Korea Investment & Securities or a custody company.

[0042] The platform server (120) may be implemented as a computer device (200) including a memory (210), a processor (220), a communication interface (230), and an input / output interface (240) as shown in FIG. 2 to issue stGold according to the staking and collateral ratio (C-Ratio) of SPDR-based token securities tGold.

[0043] Memory (210) is a computer-readable recording medium and may include a non-permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), and a disk drive. Here, the non-permanent mass storage device such as a ROM and a disk drive may be included in the computer device (200) as a separate permanent storage device distinct from the memory (210).

[0044] Additionally, the memory (210) may store an operating system and at least one program code. These software components may be loaded into the memory (210) from a computer-readable recording medium separate from the memory (210). This separate computer-readable recording medium may include a computer-readable recording medium such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, a memory card, etc. In another embodiment, the software components may be loaded into the memory (210) through a communication interface (230) other than a computer-readable recording medium. For example, the software components may be loaded into the memory (210) of the computer device (200) based on a computer program installed by files received through a network (260).

[0045] The processor (220) may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations. Instructions may be provided to the processor (220) via the memory (210) or the communication interface (230). For example, the processor (220) may be configured to execute instructions received according to program code stored in a storage device such as the memory (210).

[0046] The communication interface (230) may provide a function for the computer device (200) to communicate with other devices (e.g., an acquisition group (110), an investor (130), and a third-party custodian (140)) via a network (260). For example, requests, commands, data, files, etc. generated by the processor (220) of the computer device (200) according to program codes stored in a recording device such as a memory (210) may be transmitted to other devices via the network (260) under the control of the communication interface (230). Conversely, signals, commands, data, files, etc. from other devices may be received by the computer device (200) via the communication interface (230) of the computer device (200) via the network (260). Signals, commands, data, etc. received through the communication interface (230) can be transmitted to the processor (220) or memory (210), and files, etc. can be stored in a storage medium (the permanent storage device described above) that the computer device (200) can further include.

[0047] The input / output interface (240) may be a means for interfacing with an input / output device (250). For example, the input device may include a device such as a microphone, keyboard, or mouse, and the output device may include a device such as a display or speaker. As another example, the input / output interface (240) may be a means for interfacing with a device that integrates input and output functions, such as a touchscreen. The input / output device (250) may also be configured as a single device with the computer device (200).

[0048] Furthermore, in other embodiments, the computer device (200) may include fewer or more components than those illustrated in FIG. 2. However, it is not necessary to explicitly illustrate most conventional components. For example, the computer device (200) may omit the communication interface (230) as it is electrically connected to the terminals possessed by the acquisition group (110) and the investor (130), and the third-party custodian (140), and may be implemented to include at least some of the input / output devices (250) described above, or may further include other components such as a transceiver, an artificial intelligence model, a database, etc.

[0049] The operation of the platform server (120) described below is assumed to be performed by a more precisely described processor (220).

[0050] The platform server (120) collects gold ETFs, which are real assets, from the underwriting group (110) based on the investment subscription amount received from investors (130), and stores the gold ETFs, which are gold securities, in a third-party custodian (140). In addition, the platform server (120) tokenizes the gold ETF into a security token, creates a gold token, tGold, and issues the staked gold token, stGold, by staking the tGold at a preset collateral ratio. This allows for a two-way service that includes not only the process of issuing tokens based on gold, which is a real asset, but also the process of returning the real collateral. In addition, the platform server (120) can disclose the issuance and storage quantities of gold tokens in real time, and can bridge gold tokens issued from various security token platforms in each country to various mainnets (public chains) to provide a gold token trading service on the integrated mainnet.

[0051] Referring to FIGS. 3 and 4, the platform server will be described in more detail. The platform server (120) includes a collection unit (121), a generation unit (122), an issuance unit (123), a processing unit (124), and a distribution management unit (125).

[0052] The collection department (121) collects and stores gold ETFs that use real assets as collateral.

[0053] The collection unit (121) can collect gold ETFs, which are gold securities, from a company (SPDR) that holds gold ETFs using real assets as collateral, and store them in a third-party custodian. More specifically, the collection unit (121) can collect a certain amount of gold ETFs from a company that holds gold ETFs using real assets as collateral, such as SPDR (410), through an underwriting group, and store the collected gold ETFs in a third-party custodian. At this time, the third-party custodian can generate gold tokens in an amount equivalent to the gold securities using the gold securities as collateral, burn gold tokens in an amount included in the gold token burn request, and simultaneously withdraw and provide gold securities in an amount equivalent to the amount of the gold tokens to be burned. This may be a depository institution that is an institution related to the issuance of token securities.

[0054] The generation unit (122) tokenizes the gold ETF into a security and creates a gold token, tGold (420).

[0055] The generation unit (122) can generate tGold (420), a gold token for a gold ETF, through a security token exchange. In the token issuance procedure, the generation unit (122) can deposit gold securities, which are gold ETFs, in an amount equivalent to the gold token subscription amount received from the securities account in the investor terminal to a third-party custodian, and approve the tGold (420), which is a gold token issued by the third-party custodian. In the return procedure, the generation unit (122) according to the embodiment can transfer gold tokens in response to a request for return of gold tokens from a registered wallet in the investor terminal to the third-party custodian, confirm the gold securities that were being stored in the third-party custodian for the tGold (420), which is a gold token, and transfer the confirmed gold securities to the registered securities account in the investor terminal.

[0056] In this case, supporting gold token trading among multiple investors means recording on the blockchain of the gold token being traded that the rights to gold securities corresponding to the amount of gold tokens being traded have been changed. Furthermore, supporting gold token trading among multiple investors means only releasing gold tokens equivalent to the amount of gold securities deposited into circulation.

[0057] The issuing department (123) stakes tGold at a preset collateral ratio (430) and issues stGold (450), a staked gold token.

[0058] The issuing unit (123) can issue a staked gold token, stGold (450), by performing staking (440) that collateralizes and issues tGold (420), a gold token, according to a predetermined collateral ratio (C-Ratio, 430). At this time, the issuing unit (123) can perform staking according to a collateral ratio (430) as shown in [Formula 1] below.

[0059] [Formula 1]

[0060] stGold = tGold equivalent to 1 ounce (oz)

[0061]

[0062] The collateralization ratio (430) is adjusted annually, and stGold issued through staking at a pre-determined collateralization ratio can be rebased. Staking refers to locking a certain amount of cryptocurrency held as a stake. Cryptocurrency holders (or investors) can deposit (hold) cryptocurrency regardless of price fluctuations and earn a certain level of returns during the deposit period. This allows investors to earn a certain level of returns on their staked gold tokens (stGold (450)) during the deposit period.

[0063] According to an embodiment, the issuing unit (123) may unstake stGold and provide tGold to the investor at the investor's request.

[0064] The processing unit (124) bridges stGold from the blockchain on which tGold was issued to a heterogeneous mainnet chain.

[0065] The processing unit (124) can selectively apply, i.e. bridge, the issued stGold from the blockchain to a heterogeneous mainnet chain. While most existing bridge methods utilize heterogeneous chain Lock & Minting, the present invention utilizes the Staking & Minting method, which simultaneously performs "token unit conversion" and "chain bridging" to a heterogeneous chain using stGold, a gold token staked, as collateral. Depending on the embodiment, the token security issuance chain and the bridged integrated chain may be the same, allowing for (selectively applying) bridging to the mainnet chain.

[0066] In the platform server (120), the distribution management unit (125) can verify that only gold tokens in an amount equivalent to the deposited gold securities are in circulation by counting the amount of gold securities deposited or using a separate gold token that records the amount of gold securities deposited.

[0067] It is essential to monitor and verify that only gold tokens equivalent to the amount of gold securities deposited are in circulation. Therefore, the circulation management department (125) can monitor and verify that only gold tokens equivalent to the amount of gold securities deposited are in circulation.

[0068] Specifically, if only gold securities A, B, and C for real assets are deposited, only gold tokens in amounts corresponding to gold securities A, B, and C should be issued in the market as described above. Accordingly, when a gold token transaction occurs between multiple users, the circulation management unit (125) records the change in the rights of the gold securities corresponding to the amount of the traded gold tokens on the blockchain of the traded gold tokens, and monitors and verifies whether only gold tokens in amounts corresponding to the deposited gold securities A, B, and C are being circulated based on the information recorded on the blockchain of the gold tokens. Consequently, the circulation management unit (125) can circulate in the market only gold tokens in amounts corresponding to the deposited gold securities A, B, and C by continuing the described monitoring and verification process.

[0069] Above, it has been explained that when monitoring and verifying that only gold tokens in an amount equivalent to the deposited gold securities are in circulation, the information recorded on the blockchain of the gold token issued as a deposit of the gold securities is used, but it is not limited or restricted thereto. For example, the circulation management unit (125) can monitor and verify that only gold tokens in an amount equivalent to the deposited gold securities are in circulation by counting the storage amount of the deposited gold securities or using a separate gold token that records the storage amount of the deposited gold securities (a gold token issued separately to record the storage amount of the deposited gold securities, distinct from the gold token issued as a deposit of the gold securities).

[0070] Here, monitoring and verifying that only gold tokens equivalent to the deposited gold securities are in circulation can be performed not only by the platform server (120) as described above, but also by the third-party custodian that received the gold securities. For example, the third-party custodian can monitor and verify that only gold tokens equivalent to the deposited gold securities are in circulation by counting the amount of gold securities deposited or using a separate gold token that records the amount of gold securities deposited.

[0071] In addition, the circulation management unit (125) can provide an integrated mainnet by bridging gold tokens issued on each country's security token platform to a public chain. The circulation management unit (125) can provide an integrated mainnet by bridging (or converting, connecting) existing security token platforms to a public chain compliant with the Securities Act (or the Securities Exchange Act). More specifically, the circulation management unit (125) is characterized by providing an integrated mainnet by bridging tokens issued on security token platforms in each country to a public chain for transaction integration. At this time, the circulation management unit (125) can integrate units of tokens issued on security token platforms into units on the public chain.

[0072] Here, the security token platform is used in the issuance of gold tokens for real assets, and refers to a blockchain tokenization platform that is accessible only to local, authorized individuals, while the public chain refers to a blockchain tokenization platform that tokenizes gold securities and gold ETFs for real assets from around the world in real time, accessible to anyone around the world.

[0073] Here, referring back to FIG. 1, the platform server (120) according to an embodiment of the present invention issues the token tGold (420) through the approval process of the underwriting group (110), which is a token securities issuance related organization, and the depository institution (third-party depository institution (140)), and conversely, the token burning process when the original stock is returned is also carried out through the approval process of the related organization, thereby sharing the reliability and transparency of the existing securities market infrastructure. In addition, the platform server (120) according to an embodiment of the present invention is configured as a transparent disclosure system that can confirm the “deposit custody ETF quantity” and “token circulation and quantity by holder” through the issuance quantity (balance by wallet) of the blockchain ledger and the “deposit custody institution account API” disclosure. Therefore, the holding quantity by customer can be confirmed in real time through the KYC wallet.

[0074] A platform server (120) according to another embodiment of the present invention performs revenue assetization by applying a smart contract AMM (Automated Market Making) model to a gold token swap pool (Gold Token SWAP POOL, decentralized exchange) with unified unit specifications to obtain transaction fee revenue.

[0075] Investors (or users) can monetize their gold by providing liquidity to a gold token swap pool (a decentralized exchange) and earning trading fees. This token swap pool consists of tokens representing the same ounce (oz) of gold, which, when exchanged, result in holding the same amount of gold. The gold token exchange (swap) is implemented using an AMM smart contract that maintains a 1:1 exchange ratio even with slight price fluctuations.

[0076] To be more specific, a Liquidity Provider (LP) investor can invest in gold tokens A, B, and C in a 1:1:1 ratio in the Gold Token Swap Pool. This also applies to investing in A and B in a 1:1 ratio, or investing in A, B, C, and D in a 1:1:1:1 ratio. The composition ratio of each gold token A, B, and C may change depending on the token swap transactions of market participants (investors or users), but the sum of the quantities of each gold token A, B, and C does not change, so the gold token holding amount is maintained constant and gold token holding profits can be earned.

[0077] For example, the A+B+C = K (constant) AMM model is a model where K remains an invariant constant even if a token swap transaction occurs, and the sum of A+B+C+k (constant) remains constant regardless of any swap transaction. Applicable AMM models include UNI-SWAP, Curved Finance, or a proprietary AMM. Referring to Figure 5, an example of a token swap pool is shown, representing a 1-ounce (oz) gold token liquidity pool.

[0078] Liquidity providers (or investors) who supply gold token liquidity to the swap pool own a stake equivalent to the liquidity they provide and receive commission revenue equivalent to their stake. Consequently, liquidity providers can continuously earn trading fee revenue, effectively monetizing gold tokens.

[0079] Referring to Figure 6, it can be seen that the composition ratio of each gold token in the LP-grade token in the gold token swap pool may change, but the total number of gold tokens remains constant.

[0080] Gold tokens around the world experience price differences for various reasons, and the resulting arbitrage trading fuels active trading in gold token swap pools. The price converges to an equilibrium price based on the global gold price, and the transaction fees generated during this process become profits for liquidity providers (or investors).

[0081] In addition, according to another embodiment of the present invention, the platform server (120) tokenizes a set of gold tokens that have been supplied liquidity to the gold token swap pool, which is called an LP (Liquidity Provider) token, and tokenizes this LP share again to enable secondary trading, which is called I-Earn GOLD (Interest Earn Gold). Typically, in DeFi, it is tokenized using a revenue-generating tokenization technology such as the ERC 4626 standard in the form of a token called an Interest Bearing Token. I-Earn GOLD is a gold token that continuously earns fee revenue and can be listed on the token market again or invested in DeFi.

[0082]

[0083] FIG. 7 illustrates the process of issuing stGold according to the staking and collateral ratio (C-Ratio) of SPDR-based token securities tGold according to an embodiment of the present invention.

[0084] Referring to FIG. 7, a platform server according to an embodiment of the present invention collects gold ETFs collateralized by real assets from SPDRs to generate tGold (710), stakes tGold (710) at a preset collateral ratio (C-Ratio), and issues stGold (730), a staked gold token. Furthermore, the platform server according to an embodiment of the present invention can unstake stGold (730) with tGold (710) (Unstaking, 740). Accordingly, investors can unstake stGold (730) (740) and retrieve tGold (710) at any time. The collateral ratio can be adjusted annually, and rebasing can be performed on stGold already issued.

[0085] As illustrated in Figure 7, 1 stGold (720) is equivalent to tGold (710) equivalent to $1 oz. stGold (720) is priced in US dollars, making it unaffected by exchange rates in each country. 1 oz of tGold is equivalent to 10.80648 tGold (710), and 1 SPDR represents 0.092537 oz. The SPDR ETF initially priced at 1 oz per share, but this may vary due to the annual management fee of 0.4%.

[0086]

[0087] FIG. 8 is a flowchart illustrating an operation of a method for issuing stGold according to the staking and collateral ratio (C-Ratio) of SPDR-based token securities tGold according to an embodiment of the present invention.

[0088] The operating method of the platform server described below is assumed to be performed by a platform server (120) within a platform system that issues stGold according to the staking of SPDR-based token securities tGold and the collateral ratio (C-Ratio).

[0089] In step 810, the platform server collects and stores gold ETFs backed by real assets.

[0090] In step 810, the platform server may collect gold ETFs, which are gold securities, from a company (SPDR) that holds gold ETFs backed by real assets, and store them in a third-party custodian. More specifically, in step 810, the platform server may collect a certain amount of gold ETFs from a company, such as SPDR, that holds gold ETFs backed by real assets, through an underwriting group, and store the collected gold ETFs in a third-party custodian. At this time, the third-party custodian may generate gold tokens equivalent to the gold securities using the gold securities as collateral, burn the gold tokens in the amount included in the gold token burn request, and simultaneously withdraw and provide gold securities equivalent to the amount of the gold tokens being burned. This may be a depository institution, which is an institution related to the issuance of token securities.

[0091] In step 820, the platform server tokenizes the gold ETF to create a gold token, tGold.

[0092] In step 820, the platform server may generate tGold, a gold token for a gold ETF, through a security token exchange. In the token issuance process, the platform server may deposit gold securities, a gold ETF, in an amount equivalent to the gold token subscription amount received from the securities account in the investor's terminal to a third-party custodian and approve the tGold, a gold token issued by the third-party custodian. In the return process, the platform server according to an embodiment may transfer the gold tokens to the third-party custodian in response to a request for return of the gold tokens from the registered wallet in the investor's terminal, verify the gold securities held by the third-party custodian for the tGold, and transfer the verified gold securities to the registered securities account in the investor's terminal.

[0093] In this case, supporting gold token trading among multiple investors means recording on the blockchain of the gold token being traded that the rights to gold securities corresponding to the amount of gold tokens being traded have been changed. Furthermore, supporting gold token trading among multiple investors means only releasing gold tokens equivalent to the amount of gold securities deposited into circulation.

[0094] In step 830, the platform server stakes tGold at a preset collateral ratio and issues stGold, a staked gold token.

[0095] In step 820, the platform server may issue the staked gold token, stGold, by staking the gold token, tGold, according to a predetermined collateralization ratio (C-Ratio). At this time, in step 820, the platform server may perform staking according to the collateralization ratio (430) as shown in [Formula 1] below.

[0096] [Formula 1]

[0097] stGold = tGold equivalent to 1 ounce (oz)

[0098]

[0099] The collateralization ratio is adjusted annually, and stGold issued through staking at a pre-determined collateralization ratio can be rebased. Staking refers to collateralizing a certain amount of cryptocurrency held for the issuance of stGold. Cryptocurrency holders (or investors) can deposit (hold stakes) their cryptocurrency regardless of price fluctuations and earn a certain level of returns during the staking period. This allows investors to earn a certain level of returns on their staked gold tokens, stGold, during the staking period.

[0100] In an embodiment, at step 830, the platform server may unstake stGold and provide tGold to the investor at the investor's request.

[0101] In step 840, stGold is bridged from the blockchain on which tGold was issued to the heterogeneous mainnet chain.

[0102] Step 840 allows for selective application (i.e., bridging) of the issued stGold from the blockchain to a heterogeneous mainnet chain. While most existing bridging methods utilize heterogeneous chain locking and minting, the present invention utilizes a staking and minting method, allowing for simultaneous "token unit conversion" and "chain bridging" of stGold, a gold token staked, to heterogeneous chains. Depending on the embodiment, the token security issuance chain and the bridged integrated chain may be the same, allowing for (selective) bridging to the mainnet chain.
