Description

Technology Field

[0001] The present invention relates to a system for exchanging digital assets, a digital wallet, and an architecture for exchanging digital assets, and in particular, but not exclusively, to a system, a wallet, and an architecture integrating the same that are arranged for exchanging digital assets. Background Technology

[0002] Digital assets such as cryptocurrencies have recently been gaining popularity. Investors, including those with little experience, have shown interest in investing in cryptocurrencies or using them for their daily consumption. Companies have also been exploring options to use cryptocurrencies to fund their businesses and build interest through Initial Coin Offerings (ICOs).

[0003] Despite this interest, the adoption of cryptocurrencies in transactions by ordinary consumers has been slow. Cryptocurrencies have a misconception within existing legal and regulatory frameworks, which has consequently caused significant confusion and resistance among consumers. Furthermore, the infrastructure supporting cryptocurrency transactions is often difficult for ordinary investors to use or lacks the substantial transparency expected by users. Ultimately, because information regarding cryptocurrencies is difficult to trace compared to ordinary securities, it is challenging for ordinary investors to trade them.

[0004] According to a first aspect of the present invention, a system for digital asset exchange is provided, comprising an interface configured to receive digital asset transaction requests from a user, and a gateway configured to communicate with one or more exchanges to process the digital asset transaction requests.

[0005] In an embodiment of the first aspect, a digital asset transaction request includes the exchange of digital assets with ordinary currencies.

[0006] In an embodiment of the first aspect, the interface is further configured to receive at least one digital asset index.

[0007] In an embodiment of the first aspect, the system further includes a point service configured to perform transactions using points.

[0008] In the embodiment of the first aspect, the points have a predetermined value associated with a selected ordinary currency.

[0009] In an embodiment of the first aspect, the point service exchanges points with digital assets or conventional currencies.

[0010] In an embodiment of the first aspect, the point service is further configured to facilitate payment or transactions of points having a predetermined value associated with different ordinary currencies among a number of users.

[0011] In an embodiment of the first aspect, the point service is further configured to facilitate cross-border payment or transactions.

[0012] In an embodiment of the first aspect, the digital asset exchange is configured to receive ordinary currencies.

[0013] In an embodiment of the first aspect, when a digital asset exchange transaction is performed, a digital wallet is created for the user at the time of such transaction.

[0014] In the embodiment of the first aspect, the digital wallet includes a wallet identification code.

[0015] Preferably, the wallet identification code includes a key that is unique to each wallet and may include a private key paired with a public key that is optionally used by the wallet when transactions are performed.

[0016] In the embodiment of the first aspect, the wallet identification code is presented in the form of paper.

[0017] In an embodiment of the first aspect, the system further includes an authentication module configured to authenticate a user.

[0018] In an embodiment of the first aspect, the authentication module is further configured to verify the user based on at least one of biometric information authentication and identity document authentication.

[0019] In an embodiment of the first aspect, the authentication module includes at least one of a facial recognition camera, a fingerprint scanner, and an optical imager configured to scan a user's identity document.

[0020] In an embodiment of the first aspect, the system is further configured to interact with a user digital wallet service to facilitate the transaction of digital asset transaction requests.

[0021] In an embodiment of the first aspect, the user digital wallet service performs a compliance check before digital asset transaction requests are processed.

[0022] In an embodiment of the first aspect, compliance verification includes reviewing the history of past transactions of the digital wallet service.

[0023] In the embodiment of the first aspect, the user digital wallet service is a distributed ledger wallet.

[0024] In an embodiment of the first aspect, the gateway is further configured to deposit digital asset holdings owned by the user into a custodian configured to manage the deposited digital asset holdings when processing digital asset transaction requests.

[0025] In an embodiment of the first aspect, the deposited digital asset holdings have a market value associated with a predetermined value of points allocated to the user when processing digital asset transaction requests.

[0026] In an embodiment of the first aspect, the point service is configured to perform transactions with points without interfering with the deposited digital asset holdings managed by a custodial management institution.

[0027] In the embodiment of the first aspect, the digital asset index is updated approximately every 15 seconds.

[0028] In an embodiment of the first aspect, the digital asset index is updated based on the weighted average of the reported prices for each of the plurality of constituents.

[0029] In an embodiment of the first aspect, the digital asset index is additionally associated with an index divisor that is adjusted based on updates to the constituents after a predetermined cut-off date.

[0030] According to a second aspect of the present invention, a digital application for digital asset exchange is provided, comprising:

[0031] - A distributed ledger wallet having at least a private key and a public key for recording transactions of digital assets

[0037] In an embodiment of the third aspect, the point exchange module includes a digital payment tool. Brief explanation of the drawing

[0038] Now, embodiments of the present invention will be described by way of example with reference to the attached drawings. Figure 1 is a block diagram of an exemplary architecture for exchanging digital assets. Figure 2a is a drawing of an exemplary digital asset exchange machine (DAEM). Figure 2b is a flowchart of the operation of the DAEM of Figure 3a. Figure 3 is a screenshot of an exemplary digital wallet. Figure 4 is a block diagram illustrating the communication of an exemplary digital asset index. FIG. 5 is a block diagram illustrating a transaction between two users using the exemplary architecture of FIG. 1. FIGS. 6a and 6b are examples illustrating exemplary operations of digital assets held in a public domain and tokens / points managed in a private domain according to embodiments of the present invention. Specific details for implementing the invention

[0039] Referring to FIG. 1, a block diagram illustrating an exemplary architecture for exchanging digital assets is presented. In this embodiment, the architecture comprises a plurality of components including one or more systems (104) for exchanging digital assets, one or more digital wallets or digital wallet services (106), and one or more exchanges (102) which are expert digital asset exchanges authorized to operate for trading digital assets, such as cryptocurrencies or other forms of crypto assets and other cryptocurrencies or conventional currencies (fiat currencies), commodities, securities, assets, or derivatives. As used herein, the term “conventional currencies” will include (fiat currencies), commodities, securities, assets, or derivatives.

[0040] As described, exchanges (102) are configured to communicate with at least one digital asset exchange system (104) configured to allow digital asset transaction requests to be made by users, and preferably, the digital asset exchange systems (104) can communicate with the exchanges (102) to execute a transaction after verification.

[0041] In this example, the digital asset exchange architecture (100) includes at least one system (104) for digital asset exchange, which may also be referred to as a digital asset exchange system (104) or a digital asset exchange machine (DAEM) (104). The DAEM (104) may be used by a user to exchange digital assets or to perform any digital asset transactions. Such transactions may include the purchase or sale of digital assets using ordinary money (e.g., fiat money) along with cash, or using other forms of credit or debit facilitates or other assets or derivatives. The DAEM (104) may also be configured to perform additional transactions that may not necessarily require an exchange (102), such as the transfer of digital assets between multiple digital wallets belonging to different users or merchants.

[0042] In this exemplary embodiment, a user can interact with DAEM (104) by placing a transaction order (120) on DAEM (104). Subsequently, the transaction order (120) may be verified by various implemented security systems, including biometric scanning or other forms of authentication systems (122), to authenticate the user's identity. Once the user is authenticated, their transaction (120) request may then be received for processing.

[0043] For example, the authentication module is further configured to verify the user based on biometric information authentication, such as by using a facial recognition camera or fingerprint scanner to verify the user, and / or based on identity document authentication, such as by using an optical imager or scanner to scan the user's identity documents (e.g., identity card, passport). The authentication module may also read text using OCR methods to extract text information from scanned documents as image-text input for other purposes, such as processing digital asset transaction requests or for other purposes. Advantageously, the authentication module can facilitate compliance requirements under Know Your Client (KYC) guidelines and / or Anti-Money Laundering (AML) policies in financial services.

[0044] Alternatively, interaction with the KYC process may be performed on the user's device instead of the DEAM (104). For example, all necessary documents may be scanned and / or uploaded using the ixWallet application, and user identification authentication based on biometric information authentication may be performed through authentication on the ixWallet application and / or using security modules on the user's device. In this embodiment, the authentication module may request the user to scan a dynamic QR code displayed on the DEAM using the user's device, and subsequently, authentication of the client's device may follow using the ixWallet application. Upon successful authentication using the ixWallet application, the authentication module is notified, and subsequently, the user may continue to operate on the DEAM (104). Advantageously, this allows the user to update or upload necessary documents for KYC purposes more frequently and conveniently, and is also more desirable for some users who wish to store sensitive information only on trusted devices.

[0045] Upon a transaction request (102), the user may need to provide their digital asset wallet details. The digital asset wallet may be a cryptocurrency wallet (106) that records transactions of digital assets for a specific unique account. In some examples, such a digital wallet may operate with a unique public and private key pair that is optionally shared when a transaction is required, and the digital wallet maintains a ledger of transactions. Preferably, as in the case of certain cryptocurrencies, the ledger is distributed, which means that it is accordingly decentralized and stored on a distributed system such as a blockchain. Preferably, since all completed transactions are recorded in the blockchain ledger, the cryptocurrency wallet (106) or the ixWallet application does not necessarily need to record or store any transaction of the cryptocurrency, and the wallet (106) may simply display the recorded transactions on the blockchain upon request.

[0046] The wallet (106) may also be verified for security or compliance purposes, which, in some examples, is accomplished by a module (124) configured to verify the history of the wallet's public keys or addresses to determine whether the wallet has been involved in illegal or suspicious transactions, and to raise these warnings to review or terminate the transaction request (120) if necessary.

[0047] Subsequently, the transaction request (102) may be liquidated at one or more exchanges by DAEM (104) sending the transaction request to one or more exchanges (102) for liquidation. Depending on the specific liquidation requirements of the specific cryptocurrencies, once liquidated, the user will be notified of the completion of the transaction (120) and their digital wallet (106) will be updated.

[0048] As illustrated in this architecture (100), the user may also use the DAEM (104) to purchase cryptocurrencies with conventional currencies or other assets. This may be accomplished by providing cash or by using other credit or debit facilities (e.g., using credit cards or electronic payment systems). A conversion rate may then be applied, and a transaction request (120) may be sent to an exchange for settlement so that the user can purchase the cryptocurrencies. In this example, the DAEM (104) may be implemented as a payment module (126) or device configured to receive cash, credit card details, or bank account details for payment. This payment module (126) may be configured to receive all payment types, including cash, and accordingly may have a cash counting device. The payment module (126) may also have a credit / debit card reader, an account scanner, a keypad for account entry, as well as NFC / RFID or contactless payment conveniences.

[0049] In some examples, new users may not have a digital wallet (106) because the concept of a digital wallet may be new to some new investors in digital assets or cryptocurrencies. In such examples, DAEM (104) may be able to create a new digital wallet (106) for the user upon request. To provide the new digital wallet (106) to the user, DAEM may print or otherwise transmit a code for the user that will be the identity of their new digital wallet (106). This new code may be used for any subsequent transaction using the cryptocurrency just purchased. DAEM (104) may print a copy of this code on a paper slip, thereby providing what is referred to as a "paper wallet." The purpose of this wallet (106) is to enable the user to present the "paper wallet" in their next cryptocurrency transaction. This is particularly advantageous when new users of cryptocurrencies may be required to perform a specific one-time transaction with their cryptocurrencies. Such users may not need to maintain a digital wallet (106) for their cryptocurrency for a long period, but by being able to purchase cryptocurrency in a single basic transaction with ordinary currency, users can proceed with their subsequent transactions using their cryptocurrency for the goods or services they requested.

[0050] In another exemplary embodiment, DAEM may also undergo specific account opening procedures for specific functions requiring compliance with government or legal requirements. In these examples where a user wishes to use DAEM for these specific services, DAEM may be configured to receive identification details or other information, such as those required by the new user, before DAEM can establish an account for the new user. Subsequently, this information may be transmitted for verification at authorized or government-operated exchanges so that the initial stages of account opening can be performed.

[0051] As illustrated in this exemplary architecture, a digital wallet or digital wallet service referred to as ix wallet or ixWallet (106) is also provided. In this example, ixWallet (106) is a distributed ledger wallet that allows a user to maintain their digital asset holdings. ixWallet (106) is configured to work with one or more different digital assets and may be implemented as an interface to represent different functions for the user, including interactive functions to allow users to perform transactions with their digital assets as well as check their balances of different digital assets. Security technologies such as end-to-end email / file encryption and digital signature systems utilizing a proprietary API as a basic encryption system may also be implemented to ensure security against cyber attacks from the world of conventional computers and also against attacks from quantum computers, thereby ensuring that the digital wallet remains secure. Such technologies may be advantageous because the use of code-based encryption will remain secure despite the development of quantum computing technologies.

[0052] As illustrated in FIG. 1, both DAEM (104) and ixWallet (106) are implemented to present at least one index (130) for the user. This information is helpful because it allows the user to track the performance of their digital assets in near real-time. This index (130) may be presented as a chart on the interface of DAEM (104) or within the screen of ixWallet (106). The updating (130) of the index as well as its creation are further described below with reference to FIG. 4.

[0053] Preferably, this architecture (100) includes an ixPoint system (108) that facilitates the collection, purchase, sale, exchange, or transaction of points, also referred to as ixPoints. In this exemplary embodiment, ixPoints or points may operate as a form of digital currency used as a medium for exchange, settlement, and remittance with exchanges (102), individuals, merchants, banks, governments, etc., as well as being used like ordinary currency in exchanges for goods, services, or assets. ixPoints may be structured to be generally recognized currency, and to increase ease of use and adoption, ixPoint may also be artificially created to have the same value (1:1) as a local currency, such as the Hong Kong dollar.

[0054] For IxPoints to become a freely recognized and usable digital currency, they may operate on blockchain systems such as the ERC-20 standard and utilize the same chain system. Additionally, it may be necessary for the points to be controlled, at least partially, by a centralized institution such as a monetary authority or a central bank. While various structures can provide such central control if required, in one example, the IxPoint system can operate as a layered framework. The first layer centers on the use of blockchain technology to facilitate operations on currency and ledgers for tracking currency transactions. In turn, this first layer creates the "coin" aspect of the IxPoint system, enabling it to be exchanged.

[0055] Furthermore, the underlying technology for building the ixPoint service may include Hyperledger or Corda, the entire ixPoint system may be equipped with post-quantum computing security technology, and even future quantum computers will not be able to hack every single part of the system.

[0056] Preferably, ixPoint may be a cryptocurrency issued by a system operator, such as ixFintech, and is a stable coin whose value is strictly pegged to the Hong Kong Dollar at a 1:1 ratio. ixPoint will provide the benefits of both the Hong Kong Dollar, such as creditworthiness, and blockchain technology, such as real-time transparency. Alternatively, ixPoints can be converted from digital assets in their respective countries at denominations or multiplications (or other denomination / multiplier units) of 1, 10, 100, or 1,000, and can correspond to all global currencies if necessary.

[0057] Alternatively, ixPoint can be pegged to other local currencies and have different conversion rates. For example, the rates are within a narrow range, e.g., HK$ 0.98 per ixPoint to HK$ 1.02 per ixPoint (0.99 <X<1.01) 사이로 국한될 것으로 예상된다. ixPoint에 대한 특출한 수요가 존재할 때, 전환율은 HKD 1.01에 도달할 수 있고, 일단 이러한 상위 대역에 도달하면, IX Fintech Group은 그를 사용하여 예비금(reserve)을 시장에서 매도(short)할 것이다. 그 반대도 마찬가지로, ixPoint의 특출한 공급이 존재할 때, IX Fintech는 0.99의 하위 대역으로 HKD 1= ixPoint에서 ixPoint를 지원할 것이다. 처음에 각각의 ixPoint의 순환이 실제 HKD 1에 의해 지원되기 때문에, ixPoint를 환매하고 지원하기에 충분한 현금이 항상 시스템에 존재해야 한다.

[0058] It should be noted that factors such as market fluctuations from transactions between ixPoint holders and users can change the exchange rate. For example, when they sell or buy a significant number of ixPoints, or when blockchain delay issues also change the rate, for instance, if there is a significant delay in processing transactions for a large number of ixPoints on the blockchain, the number of ixPoints in the market will decrease, which in turn will lower the fixed rate.

[0059] As stablecoins are associated with digital assets, ixPoints enable users to transfer ixPoints to other accounts. Furthermore, since both customers and businesses appear as ixPoint users, there is no distinction in identity between them within the ixPoint system. In addition, users can use the ixPoints in their ixWallet to purchase goods and services from ix or other merchants and businesses. Other merchants and businesses can also use the ixPoint system to collect payments from customers, and ixPoints can be easily exchanged for other digital assets on our exchange, or ixPoints can be earned by selling other digital assets.

[0060] Furthermore, users can transfer ixPoint to accounts in other countries / regions and exchange them for logo currencies, thereby enabling cross-border remittances, and customers can exchange local and foreign currencies through ixPoint on DAEM. Users may only need to purchase ixPoints with one currency and then move to another machine to sell the ixPoints in order to obtain another currency.

[0061] The second layer can complement this first layer by tracking "coins" and their respective associated transactions, either through the use of a centralized system or through the use of private blockchains with merchants, exchanges, banks, government agencies, or central monetary institutions. This second layer, in turn, can provide value backed by digital currency while also reducing public blocking transaction costs and delays in completing transactions.

[0062] These points can be earned, purchased, or exchanged by transactions using DAEM (104) or ixWallet (106) or any approved transaction system, and accordingly, the points can be considered in the form of digital assets or digital currency. Subsequently, these points can be used as currency for purchasing goods or services with public utility companies, government departments, banks, professional service providers, individuals or merchants (110), or as a method to facilitate foreign exchange transactions or remittances abroad, as described below with reference to FIG. 5.

[0063] Preferably, the ixPoint system (108) is implemented so that each (one) point can be exchanged for each (one) local currency unit (e.g., each Hong Kong dollar when the system operates in Hong Kong). Maintaining such a constant exchange rate can facilitate its adoption and usability as a supplementary reward system or currency.

[0064] Accordingly, the architecture (100) can operate as a whole solution for the experience and adoption of digital assets by various users. As illustrated, the components work together to perform the transfer of digital assets, the creation of digital assets, and the destruction of digital assets, as well as the management of digital asset amounts, the reporting of digital asset holdings, and the linking of digital assets to merchants, and to perform payments in conventional currency (e.g., cash) as well as points such as IxPoints. In turn, this also enables the architecture to perform foreign exchange (FX) transactions while ensuring that Know Your Customer (KYC) and Anti-Money Laundering (AML) requirements are managed. The architecture is also advantageous because it may be possible to link financial products on a crypto index, such as the ixCrypto index, by providing tokens for financial assets, such as index fund tokens.

[0065] Additionally, examples of DAEM (104) and ixWallet (106) may be used together or separately. DAEM (104) may allow users to deposit cash (conventional currency) to purchase digital assets, as well as to sell digital assets to obtain cash. Examples of ixWallet (106) may also allow users to perform foreign exchange (FX) and transfer digital assets with other users or merchants, as well as check digital asset holdings on a distributed ledger. Preferably, ixWallet (106) may also provide functionality to allow users to check cryptocurrency indices (130), such as ixcrypto index levels. This may provide convenience to users because transactions for transferring funds overseas or to other intermediaries or merchants can be performed within a short timeframe (e.g., 30 minutes) rather than 1-2 days at a bank.

[0066] Referring to FIGS. 2a and 2b, an exemplary embodiment of a system (104) for digital asset exchange is illustrated, which includes the following:

[0067] - An interface (202) configured to receive digital asset transaction requests from a user,

[0068] - A gateway configured to communicate with one or more exchanges to process digital asset transaction requests (120). Preferably, the interface (202) is further configured to present at least one digital asset index (130). This system may also be referred to as a digital asset exchange machine (DAEM) (104).

[0069] As described, a cryptocurrency index (130), referred to as the ixCrypto index, is displayed on the top screen (202) of the machine (104). The index (130) is determined and calculated to reflect the overall performance of the cryptocurrency market and provides guidance on the performance of digital assets.

[0070] Preferably, customers can trade not only cryptocurrencies but also other types of digital assets, including real asset tokens (asset-backed tokens), stablecoins, or stablecoin tokens provided to tokenization service providers such as ixFintech.

[0071] DAEM (104) can also support other payment methods and can be equipped with all KYC functions for regulatory requirements, and accordingly, DAEM (104) can be used as a transaction point for using both conventional currencies and digital assets for government, public utility, individuals, or merchant-related services.

[0072] Preferably, DAEM (104) has three levels of security protection, and accordingly, improves their protection against current and future hacking techniques.

[0073] In one example of the operation of DAEM (104), the system (104) may be configured to allow a user to exchange (buy and sell) digital assets for ordinary currencies. This operation may follow the following procedures:

[0074] Step 1: A customer can view prices on DAEM (104) and view one or more digital assets of interest;

[0075] Step 2: The customer deposits cash into DAEM (104) or provides credit or bank conveniences;

[0076] Step 3: The customer may view the purchase of digital assets on their digital wallet, such as ixWallet (106), or the customer may redeem the digital assets later on our DAEM (104) using a printed QR code slip. These printed slips are referred to as "paper wallets".

[0077] Step 4: Customers can receive SMS and emails as records of their transactions.

[0078] A set of similar procedures is also applied to the sale of digital assets in which cash is paid by DAEM (104) or transferred to a predetermined account. Accordingly, when DAEM (104) operates within an architecture for exchanging digital assets, it may provide one or more of the following functions without limitation:

[0079] 1. Listing new cryptocurrencies and tokens and making them available for trading.

[0080] 2. Opening a digital asset paper wallet account.

[0081] 3. Exchanging cash and cryptocurrencies (buying and selling cryptocurrencies on machines).

[0082] 4. Exchanging cash and physical asset-backed tokens (buying and selling tokens on machines).

[0083] 5. Exchanging cash and securities-backed tokens (buying and selling tokens on the machine).

[0084] 6. Exchanging cash and other types of digital assets (buying and selling tokens on machines).

[0085] 7. Purchasing digital coupons and tickets.

[0086] 8. IX Point = Purchasing IX Point for 1 HKD (therefore, IXPoint can function as an example of a stable coin).

[0087] 9. Exchanging IX points for coupons, cryptocurrencies / tokens, or payments with merchants.

[0088] 10. Transfer of digital assets to other countries / regions (used with ixWallet (106) and DAEM webpages that are similar to DAEM but are effectively implemented through a website or app).

[0089] 11. A currency exchange using digital assets as an intermediary service (used with ixWallet (106) and DAEM (104) or the DAEM webpage).

[0090] 12. Viewing the performance of the ixCrypto index or other index (130).

[0091] 13. Advertising screens on the display panel of DAEM (104).

[0092] 14. Generation and Reading of QR Codes

[0093] 15. KYC function using fingerprint, passport, and HKID scanning and OCR capabilities.

[0094] 16. Post-Quantum Computing Cryptography — Code-Based Cryptography.

[0095] 17. Providing credit, loan, or financing services — thereby enabling the user to provide their identification documents and asset holdings or certificates of guarantors, followed by DAEM making payments of conventional currencies, cryptocurrencies, or Ixpoints —.

[0096] 18. Provides government services including the settlement of welfare benefits or social security pension settlements, tax settlements or refunds, fines or benefits, thereby allowing the user to provide their identification documents for the settlement of government-related settlements using ordinary currencies, cryptocurrencies, or Ixpoints.

[0097] 19. Payments or refunds to merchants or public utility companies using ordinary currencies, cryptocurrencies, or Ixpoints.

[0098] Referring to FIG. 3, an exemplary embodiment of a digital application (300) for digital asset exchange is illustrated, which includes the following:

[0099] - A distributed ledger wallet configured to operate with at least private and public keys for recording transactions of digital assets

[0100] - A gateway configured to communicate with one or more exchanges to process digital asset transaction requests; wherein, preferably, the digital application includes an interface for presenting at least one digital asset index (130).

[0101] As described, the digital wallet (106) is configured to continuously track transactions of digital assets and, accordingly, enable the owner (user) of the digital assets to continue tracking the digital assets they own. The digital wallet (106) operates as a distributed ledger and may include private and public keys (or addresses) shared during transactions so that user accounts can be identified and the ledger can be updated through a distributed process. Preferably, the application (300) providing such a digital wallet (106) or ixWallet is an app configured to operate on a computer device such as a smartphone and to communicate with a distributed system of various cryptocurrencies tracked by the digital wallet (106). This communication enables the digital wallet (106) to continue tracking the ledger and, accordingly, the amount of each digital asset that the user can hold.

[0102] The app (300) is preferably implemented to provide functions for the app to transfer digital assets to other digital wallets. In this example, the digital wallet (106) is not implemented to communicate directly with an exchange to allow the exchange of digital assets with other currencies or other digital assets, but such implementations may also be implemented. Instead, the wallet (106) is configured to connect to the DAEM (104) illustrated in FIGS. 2a and 2b to perform necessary transactions through exchanges or the ixPoint system. It is important to recognize that the DAEM (104) may also exist and operate as a service on a computing device or a cloud service.

[0103] As described, the app (300) also includes an interface representing one or more cryptocurrencies or digital asset indices (130). When operating with DAEM (104), the following features may be implemented:

[0104] A distributed ledger wallet - ixWallet (106) is a distributed ledger wallet, which means that all decentralized digital assets will be stored on the blockchain rather than in a wallet.

[0105] Cryptocurrency (Crypto) and Tokens - ixWallet (106) enables users to manage cryptocurrencies as well as other types of digital assets, including real asset tokens provided by ixFintech’s tokenization service.

[0106] ixCrypto Index - The ixCrypto Index is displayed alongside cryptocurrency prices. It is a native Hong Kong cryptocurrency index designed to reflect the overall performance of the cryptocurrency market.

[0107] Balance Check and Transfer - Customers can receive real-time updates on their digital asset account balances and easily transfer funds to other users or any other digital wallets.

[0108] Security - ixWallet (106) also has security features to prevent hacking or fraudulent authentication. Technologies that can be used include the end-to-end email / file encryption and digital signature security mentioned above.

[0109] In this example with reference to FIG. 3b, the application (300) representing ixWallet (106) is configured to allow the user to check their balances and perform digital asset transfers to other digital wallets. The features of one exemplary digital wallet include the following:

[0110] ● IxWallet (106) is a distributed ledger wallet.

[0111] ● Registered users can receive real-time updates on their digital asset accounts.

[0112] ● Users can transfer Bitcoin and Ethereum to other cryptocurrency wallets. This can also be adapted to perform blockchain transfers.

[0113] ● IxWallet (106) has built-in post-quantum computing technology for security.

[0114] ● Users can check the balance of their digital asset holdings.

[0115] ● Users can check the performance of indices (130), such as the ixCrypto index (launch of pending futures and options).

[0116] Accordingly, in one example of a digital wallet, one or more of the following functions may be performed without limitation:

[0117] 1. Exchanging IX points for coupons, cryptocurrencies / tokens, or payments with merchants.

[0118] 2. Block transaction notifications and alerts.

[0119] 3. Generation of QR codes for cash collection and remittance functions.

[0120] 4. A currency exchange using digital assets as an intermediary service (used in conjunction with DAEM (104) and / or DAEM (104) virtual service).

[0121] Referring to FIG. 4, DAEM (104) and digital wallets (106) are configured to receive a cryptocurrency index (130) referred to as ixCrypto. This index (130) is first obtained by a cloud-based service (400) in which necessary index calculation data (e.g., the price of a basket of digital assets) can be obtained from various exchanges or global information vendors (402). Subsequently, this information can be used to calculate the indices (130), which will then be transmitted to both DAEM (104) and digital wallets (106) for user access.

[0122] As illustrated in FIG. 4, the calculation of the exponent (130) is initiated by using a cloud-based storage service (400), such as AWS Storage, which is programmed to perform the following steps:

[0123] 1) IX requests data from our Source 1 (obtaining different exchange data for each constituent cryptocurrency and pair, and guidelines or multiple exchanges for multiple coins on multiple pairs in accordance with internal operating rules)

[0124] 2) The Source 1 vendor will send the signal back to the IX via API (one API in Source 1 format).

[0125] 3) IX will obtain data from Source 1.

[0126] And if Source 1 is not available, trigger an emergency plan to obtain data from Source 2 (a second API in the Source 2 format).

[0127] Next, the calculation of the exponent (130) can be performed by the following steps:

[0128] In other possible embodiments, the program will calculate the exponent (130) and distribute the exponent (130) periodically, preferably every 15 seconds, or at any suitable interval.

[0129] The fee (404) may also be paid to a data source (e.g., Nasdaq Data Fee) as part of the services that acquire the data.

[0130] Although there are various possible methods for calculating the index (130), the following exemplary processes and criteria are preferred.

[0131] First, the eligibility of the constituent items of the index (130) is considered, and preferably, a cryptocurrency is included in the universe if the cryptocurrency satisfies both of the following eligibility criteria: (a) the cryptocurrency must meet the definition of a cryptocurrency; and (b) the cryptocurrency must be publicly traded and actively traded on at least two exchanges.

[0132] Preferably, a cryptocurrency is eligible for constituent selection if it meets the following market capitalization (MC) ranking and liquidity screening selection criteria.

[0133] Market capitalization rankings are considered, whereby the cryptocurrency must be among the top n percent of free float adjusted market capitalization (“adjusted MC”), where n represents the total percentage after including the last eligible cryptocurrency, and such percentage must not be lower than 80% in any case.

[0134] In the liquidity review process, a cryptocurrency must be ranked within the top 25 in terms of 90-day average trading volume, and if a cryptocurrency within the top N in terms of adjusted MC fails to meet the liquidity requirements, that cryptocurrency will be kicked off and replaced with one or more of the following eligible cryptocurrencies until total coverage exceeds 80%.

[0135] Cryptocurrencies that meet all of the above eligibility requirements will be considered for inclusion in the ixCrypto Index (IXCI). The final selection may be determined by the operator of a platform such as IX Asia after the above criteria have been considered.

[0136] In one preferred embodiment, the number of constituent items is variable. It changes after a quarterly review when the above conditions are met.

[0137] To maintain the index in a neutral and fair manner, the constituents of the ixCrypto index may exclude coins managed or operated by any organizations that have a conflict of interest with the index. These organizations may include cryptocurrency exchanges, cryptocurrency funds, etc.

[0138] Preferably, the digital asset index may be updated in accordance with index review procedures and / or any changes to the constituents of the digital asset index. For example, the digital asset index may be updated based on an index factor adjusted based on updates to constituents after a predetermined closing date and a weighted average of the reported prices for each of the multiple constituents that may be additionally associated. The index factor is used to calculate the digital asset index.

[0139] For example, the operator of a platform such as IX Fintech may undertake regular quarterly reviews of IXCI constituents on the data deadlines at the end of March, June, September, and December of each year. The review dates will be the last business day of March, June, September, and December in HKT each year. Quarterly reviews may be completed within three weeks following the end of each quarter. In each review, there may or may not be any additions or deletions of constituents. Eligible candidates will be selected as constituents of ixCrypto in accordance with the rules below.

[0140] Rule 1 may include a "buffer rule." To avoid frequent changes to the constituent stocks, a 5% buffer zone is established for market capitalization. This means that, in terms of the adjusted MC, reorganization is required only when the sum of the weights of the constituent stocks is less than 75%. When coverage falls below 75% or the 90-day average trading volume of any existing constituent stock falls below the top 25, the buffer rule and liquidity requirements are combined. Reorganization will be performed to select new constituent stocks in accordance with the principles mentioned above.

[0141] The notification dates for changes to the constituent stocks will be the second Friday after the closing dates of March, June, September, and December.

[0142] The effective dates of changes to the constituent stocks will be the third Friday after the closing dates of March, June, September, and December.

[0143] If the first Friday after the deadline is a public holiday, the notice date and the effective date will be postponed by one week, that is, the notice date will be postponed to the third Friday and the effective date to the fourth Friday.

[0144] Rule 2 may include a “fast entry rule”, in which a new cryptocurrency will be added if it meets the following requirements for 5 consecutive days at any time: (a) ranks in the top 2 in daily trading volume; (b) has a market capitalization weighted at more than 30% of the total market capitalization; and (c) the fast entry addition will usually be implemented after the close of the 10th trading day.

[0145] Rule 3 may include a "component enhancement rule." If, after enhancement, there exists one more cryptocurrency that should have been included in the new components based on market capitalization ranking and liquidity assessment but is not included due to the rule in the heading above regarding no change, then reorganization will now be performed to include new components that have a larger market capitalization and satisfy the liquidity assessment according to the principles mentioned above.

[0146] The calculation of the Digital Asset Index or IXCI is further explained as follows.

[0147] All constituent stocks may initially be weighted by their adjusted MC. To avoid over-weighting, the maximum weight for any constituent stock is 40% (Cap) of the index's adjusted MC. If a constituent stock exceeds the Cap, its weight will be reduced to the Cap, and the excess weight will be redistributed across all other constituent stocks.

[0148] For example, the initial weights are as follows.

[0149]

[0150] Using cap adjustments, the weights of each of the constituent items A through E are determined by the following:

[0151]

[0152]

[0153]

[0154]

[0155]

[0156] Therefore, the adjusted weights are as follows.

[0157]

[0158] Accordingly, the exponent level can be calculated using the following expressions:

[0159]

[0160] Here, it is as follows:

[0161] CyptoIndex t CyptoIndex t = exponential level of t work

[0162] P i,t = Reported price for constituent i on day t (in USD)

[0163] S i = Circulating Supply for constituent stock i in the current quarter

[0164] F i = Cap factor for constituent stock i

[0165] D t = Exponent divisor

[0166] x = number of constituent stocks

[0167] In the above expression, the cap factor can be calculated as follows:

[0168]

[0169] Here, it is as follows:

[0170] F i = Cap factor for constituent stock i

[0171] w i ,adjusted = Cap-adjusted weights for constituent stock i

[0172] w i ,initial = initial weight for constituent stock i

[0173] Furthermore, the initial divisor can be calculated as follows:

[0174]

[0175] Here, it is as follows:

[0176] D0 = Divisor of the start date

[0177] P i,0 = Reported price (in USD) for constituent item i in the current quarter

[0178] S i = Circulating supply of constituent i in the current quarter

[0179] F i = Cap factor for constituent stock i

[0180] Baseline = 1000, this is the initiation index level.

[0181] x = number of constituent stocks

[0182] Preferably, the operator of a platform such as IX Fintech may undertake regular quarterly index rebalancing on data closing dates at the end of March, June, September, and December each year. The notice and effective dates coincide with the rebalancing dates mentioned above.

[0183] As previously explained, the digital asset index is additionally associated with an index divisor that is adjusted based on updates to the constituents after a predetermined deadline. For example, when the constituents change, the divisor is recalculated using the new constituents as follows:

[0184]

[0185] Here, it is as follows:

[0186] D old = Previous exponent divisor of last month

[0187] P i,t = Reported price for constituent i on day t (in USD)

[0188] S i = Circulating supply of constituent i in the current quarter

[0189] F i,new = Cap factor for constituent i of the new quarter

[0190] F i,old= Cap factor for constituent i in the last quarter

[0191] x = number of new constituent stocks

[0192] n = number of previous constituent stocks

[0193] These exemplary index (130) calculation methodologies are advantageous because they are calculated to reflect the performance of the cryptocurrency market. These indices (130) are designed to be simple to understand while providing a good representation of the crypto market. This aims to cover the top 80% of cumulative free-float market capitalization in the cryptocurrency universe, while also ranking in the top 25 based on trading volume over the 90 days prior to the review date. The index can also be capped at 40% for a single member with quarterly index reviews, and is transparently disclosed and auditable by design.

[0194] Referring to FIG. 5, the point service can additionally facilitate payments or transactions of points having a predetermined value associated with different conventional currencies among multiple users, such as, but not limited to, cross-border payments or transactions. For example, users can perform foreign exchange exchange and remittance functions using an architecture (100) for digital asset exchange. As illustrated, a user (502) located in a first location, such as Hong Kong, can first purchase (506) a cryptocurrency, such as Bitcoin, through DAEM (104) as described above with reference to FIG. 2a and 2b, using conventional currency (Hong Kong Dollar) or other assets. Subsequently, the user (502) can exchange Bitcoin (or any other digital asset) for points (508) (or ixpoints) through the ixPoint system (108). Subsequently, the points can be created on the digital wallet (106) of user A (502).

[0195] Subsequently, these points can be transferred (509) by User A (502) to a second User B (504) located in Thailand via the use of User A's digital wallet (106). Upon successful transfer (509), User B (504) will have the points in their digital wallet (106). Subsequently, User B (504) can convert the points back into cryptocurrency or digital assets, such as Bitcoin (510), via the use of their digital wallet, and, if preferred, exchange the digital assets back into their local currency (Thai Baht) via DAEM (104) located in Thailand (512).

[0196] In this example, the foreign exchange transaction is completed without any substantial delay. The conversion of cryptocurrency to ixPoint (508) as provided by the ixPoint system (108) allows for a simple and predictable transaction (510) from one currency (Hong Kong Dollar) to a second currency (Thai Baht) and vice versa. This conversion is simple and predictable because the foreign exchange transfer is not substantially different from the conventional method for the nominal FX rate of ordinary currencies or local currencies. For example, in an example where it is necessary to exchange a digital asset value pegged to HKD ixPoint for a digital asset pegged to THB ixPoint, the ixPoint calculated in HKD would simply need to be converted or exchanged to ixPoint THB according to the nominal FX rate at the time the conversion is processed, and then the ixPoints can be seamlessly transferred from User A in Hong Kong to User B in Thailand.

[0197] Referring to FIGS. 6a and 6b, exemplary operations of digital assets held in the public domain and tokens / points managed in the private domain are illustrated according to embodiments of the present invention. As previously described, digital asset holdings may be actual "cryptocurrencies" owned by a user, and transactions are recorded on a distributed system, such as a blockchain or other decentralized ledger, and in some cases, updating records of a distributed system in the public domain can be complex and time-consuming. Accordingly, it may be more desirable for transactions involving cryptocurrencies not to involve updating the decentralized ledger in the public domain in order to facilitate the "use" of cryptocurrencies in a manner similar to making payments with actual or conventional currencies, and more preferably in a manner similar to using local currencies.

[0198] According to embodiments of the present invention, systems and methods for high-frequency and cost-free digital asset transactions are provided. The methods and systems discussed herein utilize a permissioned blockchain or a distributed ledger technology (DLT) network. Because participants in permissioned blockchains are known to and trusted by the rest of the network, it is possible to achieve higher speeds and throughput than in permissionless chains. Unlike proof-of-work blockchains such as Bitcoin and Ethereum, the system may use a practical Byzantine fault-tolerant consensus algorithm to establish transaction finality. There are no mining or transaction costs, and smart contracts can be executed on a much larger scale than in public blockchains.

[0199] Preferably, when processing digital asset transaction requests, the gateway of DEAM then deposits the digital asset holdings owned by the user into a custodian configured to manage the deposited digital asset holdings, and subsequently allocates the matching value of the points / tokens to the user, similar to the ixPoints described above. Subsequently, the user can conveniently make payments in local currencies using the ixPoints, and subsequent spending / accumulation of the ixPoints may be recorded only in a private domain, such as a private server, managed by the service provider or operator of the point service system. In this exemplary operation, the point service simply records transactions using points without interfering with the deposited digital asset holdings managed by the custodian, but because the ixPoints represent the matching value of the actual digital asset holdings owned by the user deposited in the custodian, the balance of digital asset holdings in local currencies or other conventional currency units in the user's ixWallet is also known by observing the balance of available ixPoints.

[0200] Preferably, to realize the multiple identities and functionalities of ixPoint, a combination of a decentralized private chain and a centralized system will be used, wherein the inventors also refer to such a system as an IOU ("I Owe U") system. For example, an operator such as ixFintech may build a private blockchain for the final recording of all ixPoint transactions, as well as for the minting and burning of ixPoint. The blockchain system is transparent and immutable, and accordingly, ixPoint will have these advantages identical to those of other cryptocurrencies.

[0201] ixPoint transactions will temporarily use the IOU method in the first stage. Because transactions on public blockchains generally require more time to proceed (e.g., minutes on ERC20 chains, and even hours on Bitcoin chains), transactions are first recorded by the IOU, allowing transactions to be completed immediately, similar to other payment methods such as payment systems that can be used at physical stores (POS).

[0202] The operator can also set a daily settlement time to settle all transactions within the day and record all IOU transactions in the blockchain system, making these records permanent and immutable.

[0203] The architecture for exchanging digital assets can be utilized as a complete ecosystem where all products and services can be purchased by ixPoint, and people can easily exchange money and transfer funds through ixPoint associated with or backed by digital assets managed by a custodial institution.

[0204] For example, in the prior embodiment of FIG. 5, where cross-border payments or transactions can be completed using the architecture (100) for digital asset exchange, when a request is received from User A (502) in Hong Kong to transfer a specific amount of ixPoint (508) in User A's digital wallet (106) to a second User B (504) in Thailand, the system records only the change in the balance of ixPoint (508) in both users' digital wallets when completing the cross-border transaction, without interfering with the actual amount of digital asset holdings deposited with the custodian, and thus, delays caused by updating the blockchain associated with the cryptocurrency can be eliminated.

[0205] Subsequently, User B (504) may choose how to use / convert the points in his digital wallet (106), for example, simply by maintaining an ixPoint balance with a market value mirroring the ixCrypto index, in which case the deposited digital asset holdings managed by the custodian institution remain unchanged. Alternatively, User B may exchange the digital assets back into his local currency (Thai baht) through DAEM (104) located in Thailand (512), and then the system will proceed with the burning of ixPoint upon withdrawal of Thai baht or other currencies of the same market value, and the request for burning will be described later in this disclosure.

[0206] If User A or User B decides to sell cryptocurrencies and the new owner of the digital asset holdings is not a user of the ixPoint / ixWallet system, the transaction of the digital asset holdings / cryptocurrencies will be completed by updating the actual blockchain, and then, the amount of the deposited digital asset holdings matching the value of the ixPoints being sold will be released from the custodian in the public domain after the request for burning is completed, similar to the example of local currency withdrawal.

[0207] Preferably, the point exchange module may be used or placed in various physical stores such as brokers and banks in the financial sector, street vendors, restaurants, and vending machines in the food and restaurant sector, stores, malls, or supermarkets in the retail sector, and may even be further configured to facilitate digital payments in physical stores associated with points by utilizing one or more digital payment tools for payments in tourism and hospitality or any possible services.

[0208] To facilitate digital payments, digital payment tools such as terminals or kiosks may be installed to scan or receive payment requests from users. For example, users may scan merchants' QR codes or show their own QR codes to merchants to complete payments when purchasing goods and services. Alternatively, or optionally, hardware such as RFID / NFC readers and appropriate software may be used to read payment information from payment cards or smartphone applications, similar to other contactless payment systems.

[0209] It should be recognized by a person skilled in the art that transactions performed through a system involving the transfer of cryptocurrency or digital currency (e.g., Bitcoin, fiat currencies of virtual amounts, tokenized assets on any blockchain, etc.) may be any type of digital asset. In other words, the methods and systems discussed herein may be applicable to transactions of any type of digital asset. Although the system may be described with respect to the transfer of digital currency, the techniques discussed herein are accordingly applicable to transactions of any type of digital asset.

[0210] Referring to FIG. 6a, to use the system (600), a user (601) may transfer their digital asset holdings, which are innately located on other blockchains (611), to the system operator's custodian (602) via a user device (610) (e.g., a cryptocurrency wallet) or using a DEAM, that is, an entity holding an equivalent amount of assets as tokenized copies (tokens) within the system (e.g., a multisig wallet, a DAO, or a vault smart contract). Tokens (620) of the same amount, pegged to the value of the original digital assets, will be issued on the system in the private domain. The system may continue to monitor transactions on the blockchain network (611), and once a transaction is confirmed using sufficient confirmations (e.g., proofs) on the blockchain, the tokens (620) issued on the system will be unlocked and may be used within a point service system independent of the blockchains or distributed ledger.

[0211] When the tokens (120) need to be exchanged back into the original digital assets, referring to FIG. 6b, the user (601) can send a request to burn the tokens (620) to the custodian (603), and a smart contract within the system (600) can be created using the user's device (612) (a mobile app or web-based system capable of calling the API of the system (600)). After the burn request is committed, the digital asset reserves can then be released from the reserve custodian (602) to the user's device (610) (an address where the user prefers to receive the digital asset reserves) via a public blockchain network.

[0212] In this example, a user who owns tokens representing their digital assets can freely transfer their ownership to another user on the system at any time by sending a transaction request to the system. Transactions can be performed on a system capable of using a real Byzantine fault-tolerant consensus algorithm to establish transaction finality.

[0213] Preferably, the system (600) may use a Practical Byzantine Fault Tolerance (PBFT) consensus algorithm to establish transaction finality. In particular, PBFT is a voting-based consensus algorithm as follows:

[0214] ● Byzantine Fault Tolerance: As long as a minimum percentage of nodes are connected, functioning properly, and behaving fairly, network liveness and safety are guaranteed even if some nodes are failed or malicious.

[0215] ● Non-forking: Unlike lottery-style consensus algorithms such as Proof of Work (PoW) or Proof of Elapsed Time (PoET), the blocks committed by nodes are final.

[0216] ● Leader-based: A primary node (leader) is selected and responsible for generating candidate blocks, while secondary nodes (followers) vote on the blocks generated by the primary node. Changes in the leader occur in a round-robin order.

[0217] ● Communication Intensive: Nodes send many messages to reach consensus, commit blocks, and maintain healthy leader nodes.

[0218] Advantageously, the methods and systems discussed herein can increase interoperability between different blockchains, and native tokens can essentially proceed to chain-cross by converting digital assets into tokenized versions supported on different blockchains, because many blockchains have their own proprietary token standards (e.g., ERC-20 for Ethereum, NEP-5 for NEO).

[0219] Furthermore, the system can effectively reduce transaction times and fees because public blockchains like Bitcoin are slow and expensive to use. By generating tokenized copies of digital asset holdings—such as fiat coins or mirror coins—in the system's private domain, non-inherent tokens can be transferred within the same location with faster transaction times and without fees.

[0220] Furthermore, since both ixPoint and other digital assets are built on a blockchain network, it is more convenient for investors to purchase digital assets through ixPoint. The value of ixPoint is embedded when it acts as a medium that facilitates investors in purchasing digital assets. Advantageously, investors can buy / sell digital assets simply by buying or selling ixPoints or fiat coins.

[0221] Embodiments of the present invention also transform the traditional financial environment into a Fintech ecosystem because the ixPoint service has many advantages over traditional fiat currency and blockchain technology, and the ixPoint mirror coin solution also solves many problems related to finance in daily life, such as everyday microtransactions, digital assets, and securities.

[0222] These embodiments may also be advantageous in that they provide a fiat coin system based on a local currency that mirrors a decentralized blockchain-based coin or cryptocurrency. The ixPoint system facilitates payment / transactions using cryptocurrencies linked to a digital wallet owned by a user, wherein ixPoints are allocated to the user's digital wallet when a cryptocurrency of a specific value is deposited on an exchange platform, and ixPoints represent the real-time market value of the deposited cryptocurrency in local currency units managed by a custodial institution separated from the IX Point platform.

[0223] Subsequent transactions involving a digital wallet process only allocated ixPoints rather than deposited cryptocurrency managed by a custodian; accordingly, the transaction will be much simpler and faster than processing actual cryptocurrency, because the transaction does not involve updating the blockchain associated with the cryptocurrency until the deposited cryptocurrency is additionally traded, withdrawn, or transferred by the user. ixPoints are centralized fiat coins stored in the digital wallet and managed by the IX Point system, which mirrors the decentralized blockchain-based coins of cryptocurrency.

[0224] Furthermore, embodiments of the present invention also provide a unique clearing methodology for accepting price fluctuations of cryptocurrency and facilitating transactions using cryptocurrency. In particular, the ixPoint system synchronizes IX Points in a digital wallet in real-time or at least periodically according to the market value of cryptocurrency, and accordingly, by mirroring the actual market value of deposited cryptocurrency managed by a custodian institution, the user can flexibly use mirrored cryptocurrency similar to other digital wallets based on deposits of local currency or other currency.

[0225] Lastly, but also importantly, special electronic systems and devices of some preferred embodiments may be included to complete transactions using cryptocurrency in a physical store. Using such a system architecture, dedicated kiosks such as DEAM, and mobile payment tools such as RFID / NFC cards and / or applications installed on mobile devices may be implemented to facilitate cryptocurrency-based transactions through mirror coins or ixPoints assigned to a user's account.

[0226] Although not required, the embodiments described with reference to the drawings may be implemented as an application programming interface (API) or as a series of libraries for use by developers, or may be included within other software applications such as terminals, personal computer operating systems, or portable computing device operating systems. Generally, since program modules include routines, programs, objects, components, and data files that assist in the performance of specific functions, a person skilled in the art will understand that the functionality of a software application may be distributed across a number of routines, objects, or components to achieve the same functionality desired herein.

[0227] Additionally, it will be recognized that any suitable computing system architecture may be utilized where the methods and systems of the present invention are implemented wholly or partially by computing systems. This may include standalone computers, networked computers, and dedicated hardware devices. Where the terms “computing system” and “computing device” are used, these terms are intended to cover any suitable arrangement of computer hardware capable of implementing the described functions.

[0228] It will be recognized by those skilled in the art that numerous variations and / or modifications to the present invention, as shown in specific embodiments, may be made without departing from the spirit or scope of the invention as broadly described. Accordingly, these embodiments should be regarded as illustrative rather than restrictive in all respects.

[0229] Any reference to prior art contained herein shall not be taken as an acknowledgment that such information is ordinary general knowledge, unless otherwise indicated.
