    [0024] [0024] Examples of embodiments are described in detail here, and examples of exemplary embodiments are presented in the accompanying drawings. When the following description refers to the attached drawings, unless otherwise specified, the same numbers in different attached drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with one or more embodiments of this specification. On the contrary, the embodiments are only examples of apparatus and methods which are described in the appended claims in detail and consistent with some aspects of one or more embodiments of the present specification.
    [0025] [0025] It is worth noting that, in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the steps included in the method may be more or less than those described in this specification. In addition, a single step described in this specification can be broken down into a plurality of steps in other embodiments for description, and a plurality of steps described in this specification can be combined into a single step in other embodiments for description. description.
    [0026] [0026] Figure 1 is a flow chart that illustrates a method of issuing a trust protocol asset, according to an example of an embodiment. As shown in Figure 1, the method can include the following steps.
    [0027] [0027] Step 102: A trust protocol anchor determines that an asset outside the chain of a specified quantity is in a frozen state.
    [0028] [0028] In one embodiment, the anchor function may be performed by a trusted protocol member, or the anchor may not be related to a trusted protocol member, that is, the anchor function is not necessarily performed by a trusted protocol member.
    [0029] [0029] In one embodiment, members of the Trust Protocol may be financial institutions or other forms of organizations or platforms that support an asset transfer service. The embodiments are not limited in this specification. The anchor role can also be played by financial institutions or other forms of organizations or platforms that support an asset transfer service. The embodiments are not limited in this specification.
    [0030] [0030] In one embodiment, an asset type outside the chain can be funds or bonds. The asset outside the chain can be in a predetermined account and the predetermined account is in a frozen state.
    [0031] [0031] In one embodiment, the frozen state indicates that the asset outside the corresponding chain cannot be used by other services and is isolated and protected from other factors. Different degrees of freezing are used for different needs. For example, in a relatively strong degree of freeze, bankruptcy settlement isolation can be performed on assets outside the chain. As such, even if the anchor to freeze the asset outside the chain is bankrupt, a frozen state of the asset outside the chain is not affected.
    [0032] [0032] In one embodiment, the predetermined account can be a specific frozen asset account specified by the trust protocol anchor. That is, the account is used only to store the asset outside the chain that needs to be frozen. For example, the default account may be an account opened at a bank by the trust anchor. In other embodiments, the predetermined account can be an account specified by another trust protocol node or another type of account. The embodiments are not limited in this specification.
    [0033] [0033] In one embodiment, the type of asset outside the chain can be a real asset and that type of asset outside the chain can be in a predetermined storage location. Information collection can be performed on objects in the predetermined storage location using an information collection device. As such, it can be determined that the asset outside the chain is in a frozen state when the information collection device collects information about the asset outside the chain at the predetermined storage location. For example, the information collection device may include an image collection device, and the image collection device may collect images at the predetermined storage location. Thus, when it is determined that the images include the asset outside the chain by means of image content analysis, it can be determined that the information collection device collects information about the asset outside the chain at the predetermined storage location. Another example, the information collection device can include an RFID reader, and each object in the predetermined storage location has an RFID tag, and the RFID reader can read the RFID label in the predetermined storage location. In this way, when the RFID tag information that corresponds to the asset outside the chain is read (for example, the object ID that corresponds exclusively to the asset outside the chain), it can be determined that the information collection device collects information about the active outside the chain at the predetermined storage location.
    [0034] [0034] Step (104): The trust anchor issues a trust protocol asset in a trust protocol, where an amount of the trust protocol asset is not greater than the specified value, and a transaction record of the trustee asset in a trustee accounting record contains a freezing certificate for the asset outside the chain.
    [0035] [0035] In one embodiment, the trust protocol asset issued by the trust protocol anchor in the trust protocol can be of the same type as an asset outside the corresponding chain. For example, when the asset outside the chain is RMB, the trust protocol asset issued is also RMB; when the non-chain asset is USD, the trust protocol asset issued is also USD. In another example, when the asset outside the chain is securities, the trust protocol asset issued is also securities; when the asset outside the chain is a property, the trust protocol asset issued is also a property.
    [0036] [0036] In one embodiment, the trust protocol asset issued by the trust protocol anchor in the trust protocol and an asset outside the corresponding chain can be of different types. For example, the asset outside the chain can be assets and the trust protocol issued is an equivalent security. In another example, the asset outside the chain may be USD, and the issued trust protocol asset is an equivalent trust protocol token.
    [0037] [0037] In one embodiment, the trust anchor is configured to anchor the trust protocol asset and the out-of-chain asset so that the out-of-chain asset can be converted into an equivalent trust protocol asset using the anchor, or the trust protocol asset can be converted to an asset outside the equivalent chain using the anchor. As such, a one-to-one mapping is implemented between the trust protocol asset and the asset outside the chain.
    [0038] [0038] In one embodiment, the freeze certificate is added to the transaction record that corresponds to the trust protocol asset, so that the freeze certificate can be used to prove the reliability of the trust protocol anchor and indicate that the trust anchor can convert a related trust protocol asset into an asset outside the chain. As such, an association relationship between the trust protocol asset and the out-of-chain asset can ensure that the trust protocol asset is of real value and is not issued randomly by the trust protocol anchor.
    [0039] [0039] In one embodiment, the trust protocol anchor can actively generate the freezing certificate after the freezing of the asset outside the chain. For example, the trust anchor signs the freeze certificate generated by the trust anchor and adds the freeze certificate to the transaction record.
    [0040] [0040] In one embodiment, the trust protocol anchor can receive the freezing certificate from a trusted third party.
    [0041] [0041] Figure 2 is a flowchart that illustrates a method of redemption of a trust protocol asset, according to an example of an embodiment. As shown in Figure 2, the method can include the following steps.
    [0042] [0042] Step (202): A trustee anchor receives a redemption request for a trustee asset initiated by a trustee member.
    [0043] [0043] In one embodiment, the trustee member may initiate a request in particular to convert the trustee asset into an asset outside the corresponding chain. In other embodiments, the trustee member may perform a related transaction that is equivalent to initiating a request to convert a trustee asset, into an asset transfer process (such as shipping), especially when the trust protocol assets of the trust member are converted to assets outside the chain.
    [0044] [0044] Step (204): The trust anchor determines whether there is a freezing certificate that corresponds to the trust protocol asset based on the accounting data in a trust protocol accounting record.
    [0045] [0045] Step (206): The trust anchor converts the trust protocol asset into an asset outside the chain of a corresponding value when there is a freezing certificate that corresponds to the trust protocol asset, to provide the asset out of jail to the trusted protocol member.
    [0046] [0046] In one embodiment, the trust protocol asset can be issued by the previous trust protocol anchor and, in this embodiment, the trust protocol asset is still converted by the trust protocol anchor to the outside asset corresponding chain. The trust protocol asset can be all or part of the asset issued by the trust protocol anchor and therefore the trust protocol anchor can convert the trust protocol asset to all or part of the asset outside the corresponding chain based on in a real situation.
    [0047] [0047] In one embodiment, a transaction record that corresponds to the trust protocol asset can be searched for by a freezing certificate. When the transaction record contains a freeze certificate, it is determined that there is a freeze certificate that corresponds to the trust protocol asset. In this way, the valid value of the trust protocol asset can be verified using the asset outside the chain that corresponds to the freezing certificate to reduce the possible risk caused by the redemption. In addition, there may be other methods for verifying that a freeze certificate exists that matches the trust protocol asset. The embodiments are not limited in this specification. In particular, the trust protocol asset can be issued by another anchor and a freezing certificate for the trust protocol asset is verified. After the verification is successful, the trustee asset is exchanged for an asset outside the corresponding chain with the trustee member. It is equivalent to the following case: The trust anchor exchanges the trust protocol asset for the asset outside the chain, and the trust anchor can also exchange the trust protocol asset with other trust protocol nodes or exchange the trust protocol asset for an asset outside the corresponding chain with the other previous anchor that issues the trust protocol asset.
    [0048] [0048] In one embodiment, the freezing certificate may include a signature from a trusted third party or an anchor that issues the trust protocol asset (for example, the trust protocol anchor or the other previous anchor). For example, when the asset outside the chain is frozen by the trust protocol anchor, the freezing certificate can be generated and signed by the trust protocol anchor, or the freezing certificate is provided to the trusted third party by the trust protocol anchor. and is signed by the trusted third party after the frozen state of the asset outside the chain is confirmed by the trusted third party. In another example, when the asset outside the chain is frozen by the other previous anchor, the freezing certificate can be generated and signed by the other anchor, or the freezing certificate is provided to the trusted third party by the other anchor and is signed by the trusted third party after the frozen state of the asset outside the chain is confirmed by the trusted third party.
    [0049] [0049] In one embodiment, when the freezing certificate is signed by another anchor or the trusted third party, the trust protocol anchor can initiate a consultation with the other anchor or the trusted third party to determine whether an asset outside the corresponding chain is still in a frozen state. When it is confirmed that the asset outside the chain is still frozen, the trust anchor rescues the corresponding trust protocol asset. Otherwise, the trust protocol anchor may refuse to redeem the asset.
    [0050] [0050] In one embodiment, when assets outside the chain (ie frozen assets) that match a freezing certificate are frozen by the trust protocol anchor, the trust protocol anchor can thaw frozen assets that match the freezing certificate for the exchange of trust protocol assets for assets outside the chain. Thawed assets can then be transferred to the asset storage location specified by the trust protocol member. For example, when assets are funds, the asset's storage location can be an account specified by the trustee member; in another example, when assets are assets, the asset's storage location can be a deposit specified by the trustee member.
    [0051] [0051] In one embodiment, regardless of whether frozen assets are frozen by the trust anchor, the trust anchor can exchange the trust protocol assets for other assets, and the other assets are different from the frozen assets that correspond to the freezing certificate.
    [0052] [0052] In one embodiment, the trust anchor can verify an issuing part of the trust protocol asset and a holder of the trust protocol asset. The trustee anchor converts the trustee asset that has a freezing certificate corresponding to the out-of-chain asset when the issuing party of the trustee asset is the trustee anchor and the trustee member is the holder of the trust protocol asset. Otherwise (for example, the issuing party to the trustee asset is not the trustee anchor, or the trustee member is not the owner of the trustee asset), even if there is a freezing certificate. for the trust protocol asset, the trust anchor may refuse to complete the redemption.
    [0053] [0053] In one embodiment, after completing the redemption, the trust anchor can transfer the trust protocol asset to a specific retirement account. There is internal transfer permission and no transfer permission outside to access the specific retirement account. In this way, the trust protocol assets that were redeemed are written off, to prevent the same trust protocol asset from being redeemed multiple times.
    [0054] [0054] To facilitate understanding, the following describes a technical solution of this specification using an example of issuing and redeeming a trust protocol asset. Figure 3 is a schematic diagram illustrating a scenario for issuing a trust protocol asset, according to an example of an embodiment. As shown in Figure 3, suppose that a third-party payment platform operates digital wallet A (simply called wallet A), wallet A is a member of a trust protocol, the trust protocol also includes anchor B, and portfolio A can obtain the trust protocol asset issued by anchor B using the technical solution of this specification.
    [0055] [0055] Anchor B can issue trust protocol assets to portfolio A and trust protocol assets can include any type of assets, such as cash, bonds, stocks or properties (such as properties, vehicles and goods). The embodiments are not limited in this specification. As shown in Figure 3, as a member of the trust protocol, portfolio D, bank E, etc. already have the trust protocol asset that is issued by anchor B. For example, portfolio D holds a 2,000 RMB trust protocol asset that is issued by anchor B, and bank E has a trust protocol asset of 5,000 RMB that is issued by anchor B. Anchor B can record a membership status for each member for the trust protocol asset issued by anchor B in the trust protocol ledger that corresponds to the trust protocol and maintains the change in conservation status.
    [0056] [0056] Suppose portfolio A wants to obtain the 1,000 RMB trust protocol asset issued by anchor B. That is, anchor B issues a trust protocol asset to portfolio A and the trust protocol asset can be 1,000 RMB funds or it can be another asset worth
    [0057] [0057] Anchor B can issue the 1,000 RMB trust protocol asset to portfolio A in the following steps.
    [0058] [0058] Step 1: Portfolio A transfers 1,000 RMB to anchor B.
    [0059] [0059] In one embodiment, wallet A and anchor B open a bank C account separately. For example, as shown in Figure 3, account 1 belongs to wallet A, and account 2 and account 3 belong to anchor B. Therefore, wallet A can trigger account 1 to transfer 1,000 RMB to account 2 or account 3.
    [0060] [0060] In one embodiment, anchor B can agree in advance that objects that wish to issue trust protocol assets at anchor B transfer corresponding funds to a specified account. For example, the account can be account 2 of bank C or another specified account. Therefore, wallet A can transfer 1,000 RMB from account 1 to account 2. Certainly, wallet A can also transfer 1,000 RMB from account 1 to account 3 and notifies anchor B using a predetermined path, so that anchor B transfers 1,000 RMB funds from account 3 to account 2.
    [0061] [0061] In one embodiment, during the transfer, wallet A may indicate in the transfer note the ID of the member and the deposit instruction of wallet A in the trust protocol. After receiving the transfer notice, anchor B can determine that portfolio A needs to issue the transferred 1,000 RMB as trust protocol funds by analyzing the member ID and deposit instruction.
    [0062] [0062] In one embodiment, assume that the initial funds in account 1 are 1,000 RMB, that the initial funds in account 2 are
    [0063] [0063] Step 2: Anchor B freezes the funds transferred by portfolio A and generates a freezing certificate.
    [0064] [0064] In one embodiment, account 2 can be a specific frozen fund account defined for anchor B, so that
    [0065] [0065] In one embodiment, anchor B can freeze account 2 or freeze funds of 1,000 RMB in account 2. Embodiments are not limited in this specification. In addition, anchor B can generate a freezing certificate for the freezing operation and sign the freezing certificate.
    [0066] [0066] In one embodiment, to increase the reliability of the freezing certificate, anchor B can cooperate with a trusted third party (such as an authorized institution or a supervisory department) and the trusted third party signs the freezing certificate after the third reliable to confirm that anchor B performs the freezing operation.
    [0067] [0067] Step 3: Anchor B issues an asset in a trust protocol and adds the freezing certificate to a transaction record that corresponds to the asset in an accounting record of the trust protocol.
    [0068] [0068] In one embodiment, an asset issue operation performed by anchor B in the trust protocol can form a corresponding transaction record in the trust protocol accounting record to prove that the asset is real and valid.
    [0069] [0069] In one embodiment, the freezing certificate is added to the transaction record that corresponds to the asset.
    [0070] [0070] Step 4: Anchor B registers the trust protocol asset issued as a balance of trust maintained by portfolio A.
    [0071] [0071] In one embodiment, assume that only portfolio D and bank E initially hold the trust protocol assets issued by anchor B. For example, as shown in Figure 3, portfolio D holds 2,000 RMB and the bank And it holds 5,000 RMB. If portfolio A has the trust protocol assets issued previously, in addition to portfolio D and bank E, portfolio A also holds 1,000 RMB issued by anchor B, as shown in Figure 4.
    [0072] [0072] For example, portfolio A holds 1,000 RMB funds issued by anchor B. It is worth noting that “1000” shown in Figure 4 is just a number in the accounting record of the trust protocol and is created and registered by the anchor B for portfolio A. Only when anchor B can convert the number "1000" to the asset outside the 1,000 RMB chain, can the number "1000" actually represent "1,000 RMB". Therefore, the freezing certificate is added in step 3 to prove that anchor B can convert the number “1000” to the asset outside the 1,000 RMB chain.
    [0073] [0073] Figure 5 is a schematic diagram that illustrates a scenario for the redemption of a trust protocol asset, according to an example of an embodiment. As shown in Figure 5, assume that portfolio A holds the 1,000 RMB trust protocol asset issued by anchor B, and the asset can be converted out of the 1,000 RMB chain in the following method.
    [0074] [0074] Step 1: Portfolio A initiates a redemption request for anchor B using a bridge module between portfolio A and a trust protocol.
    [0075] [0075] In one embodiment, portfolio A may indicate the trust protocol assets that must be redeemed in the redemption request. As such, anchor B converts the trust protocol assets into out-of-chain assets and supplies the out-of-chain assets to portfolio A. For example, when a trust protocol asset that needs to be redeemed is a trust protocol asset issued by anchor B, portfolio A can indicate the amount of funds to be obtained through redemption in the redemption request. For example, portfolio A may mark the amount of funds as 1,000 RMB.
    [0076] [0076] Step 2: Anchor B can determine a transaction record that corresponds to a trust protocol asset to be redeemed and verify that the transaction record contains a freezing certificate.
    [0077] [0077] In one embodiment, when portfolio A needs to make a transfer to bank E, for example, when portfolio A needs to pay bank E with a 500 RMB trust protocol asset issued by anchor B, the balance of trust held by portfolio A and issued by anchor B can be decreased by 500 RMB, and the balance of trust maintained by bank E and issued by anchor B can be increased by 500 RMB. When portfolio A needs to make a transfer to portfolio Q which is not shown in the figure, for example, when portfolio A needs to pay portfolio Q with a 500 RMB trust protocol asset issued by anchor B, an intermediary member between portfolio A and portfolio Q need to be found. For example, suppose bank E separately stores trust protocol balances that are issued by anchor B and anchor P which is not shown in the figure. The balance of trust held by portfolio A and issued by anchor B can be reduced by 500 RMB, and the balance of trust maintained by bank E and issued by anchor B can be increased by 500 RMB. In addition, the balance of trust protocol maintained by bank E and issued by anchor P can be reduced by 500 RMB, and the balance of trust protocol maintained by portfolio Q and issued by anchor P can be increased by 500 RMB. As such, wallet A pays 500 RMB to wallet Q.
    [0078] [0078] In one embodiment, anchor B can redeem trust protocol assets issued by other anchors in place of anchors, as long as anchor B determines that trust protocol assets are valid and determines that anchors that issue the trust protocol assets have sufficient redemption capacity using a freezing certificate.
    [0079] [0079] Step 3: Anchor B decreases a trust protocol asset held by portfolio A and issued by anchor B by 1,000 RMB and transfers 1,000 RMB from account 2 or account 3 from anchor B to bank C to account 1 in the portfolio THE.
    [0080] [0080] In one embodiment, anchor B can maintain a write-off account of the trust protocol asset shown in Figure 6 and Figure 7. For example, the write-off account of the trust protocol initially holds the write-off protocol asset 5,000 RMB trust issued by anchor B, and then the 1,000 RMB trust protocol issued by anchor B and held by portfolio A is transferred to the trust protocol asset write-off account to write off the trust protocol asset trust of
    [0081] [0081] In one embodiment, as shown in Figure 6, anchor B can thaw 1,000 RMB previously frozen in account 2, and transfer 1,000 non-frozen RMB to account 1. As such, the transfer is completed. In other embodiments, as shown in Figure 7, anchor B can transfer 1,000 RMB from account 3 that is not related to the frozen funds to account 1. As such, the transfer is also completed. The embodiments are not limited in this specification. In fact, in addition to bank C, if anchor B and portfolio A have accounts with other banks, anchor B and portfolio A can also complete a transfer using banks. The embodiments are not limited in this specification.
    [0082] [0082] Figure 8 is a schematic diagram illustrating the rescue of a trust protocol asset in place of another anchor, according to an example of an embodiment. As shown in Figure 8, assume that portfolio A holds a 1,000 RMB trust protocol asset and the trust protocol asset is issued by anchor G. However, for some reasons, portfolio A wants to redeem the protocol asset at anchor B. Anchor B can determine that the trustee asset is issued by anchor G using a trustee transaction record in a trustee accounting record. If the transaction record contains a freezing certificate signed by anchor G or a trusted third party, it indicates that anchor G freezes an asset outside the chain with an equivalent or greater value when issuing the trust protocol asset, and anchor B can determine that the trust protocol asset is real and valid. Of course, anchor B can also temporarily initiate a query for anchor G, to determine whether the related off-chain asset is still in a frozen state and is sufficient to redeem the trust protocol asset. When anchor G returns confirmation information from the frozen state to anchor B, anchor B can determine that the related off-chain asset is still frozen and is sufficient to rescue the trust protocol asset.
    [0083] [0083] Therefore, anchor B can reserve the related trust protocol asset and transfer the trust protocol asset from portfolio A to anchor B's trust protocol account and transfer 1,000 RMB from account 2 or account 3 to account 1 corresponding to portfolio A.

    [00105] [00105] It is also worth noting that the terms "include", "contain" or any other variants are intended to cover a non-exclusive inclusion, therefore, a process, a method, a product or a device that includes a list of elements not only include these elements, but also include other elements that are not expressly listed, or include elements inherent in such a process, method, product or device.
    [00106] [00106] The specific embodiments of this specification are described above. Other embodiments fall within the scope of the appended claims. In some situations, the actions or steps described in the claims can be performed in an order different from the order in the embodiments and the desired results can still be achieved. In addition, the process represented in the accompanying drawings does not necessarily require a specific order of execution to achieve the desired results. In some embodiments, multitasking and parallel processing can be advantageous.
    [00107] [00107] The terms used in one or more embodiments of this specification are merely to illustrate specific embodiments, and are not intended to limit one or more embodiments of this specification. The terms "a" and "o" in singular forms used in one or more embodiments of this specification and the appended claims are also intended to include plural forms, unless clearly stated to the contrary in the context. It should also be understood that the term “and / or” used in this specification indicates and includes any or all possible combinations of one or more associated listed items.
    [00108] [00108] It should be understood that although the terms "first", "second", "third", etc. can be used in one or more embodiments of this specification to describe various types of information, the information is not limited to terms. These terms are used only to differentiate information of the same type. For example, without departing from the scope of one or more embodiments of this specification, the first information can also be referred to as second information, and similarly, the second information can be referred to as the first information. Depending on the context, for example, the word "if" used here can be explained as "while", "when" or "in response to the determination".
    [00109] [00109] The preceding descriptions are only examples of embodiments of one or more embodiments of this specification, but are not intended to limit one or more embodiments of this specification. Any modification, equivalent substitution, improvement, etc., made without departing from the spirit and principle of one or more embodiments of this specification will fall within the scope of protection of one or more embodiments of this specification.
    [00110] [00110] In the context above, Figure 13 is a flowchart that illustrates an example of a method implemented by computer (1300) to support a trust protocol asset issued in a trust protocol, in accordance with an embodiment of this invention. For clarity of presentation, the description that follows generally describes the method (1300) in the context of the other figures in this description. However, it will be understood that method (1300) can be performed, for example, by any system, environment, software and hardware, or a combination of systems, environments, software and hardware, as appropriate. In some embodiments, several steps of the method (1300) can be performed in parallel, in combination, in loops or in any order.
    [00111] [00111] In (1302), a trust protocol anchor determines that an asset outside the chain of a certain amount is in a frozen state. As described above in association with Figures 1-8, the trust anchor may be a trust member, a financial institution or other forms of organizations or platforms that support an asset transfer service. The asset outside the chain can be funds, bonds or a real asset (which can have a radio frequency identification tag). In some embodiments, the asset outside the chain may be in a predetermined account with special access permissions. As such, the trust protocol anchor can determine whether the predetermined account is in a frozen state by consulting the operation's permission to access the predetermined account.
    [00112] [00112] In (1304), the trust protocol anchor issues a trust protocol asset in a trust protocol. The trust protocol asset can be valued within the particular amount of the asset outside the chain that is in the frozen state. The issuance of the trust protocol asset allows the trust protocol asset to circulate in the trust protocol for consumption by the trust protocol members. From (1304), the method (1300) proceeds to (1306).
    [00113] [00113] In (1306), the trust anchor publishes a transaction record in a trust protocol accounting record. The transaction record includes a freeze certificate showing that the issued trust protocol asset is supported by the asset outside the chain in the frozen state. In one example, the trust asset issued by the trust anchor in the trust protocol can be of the same type as an asset outside the corresponding chain. In another example, the trust protocol asset issued by the trust anchor in the trust protocol and an asset outside the corresponding chain can be of different types. Here, the freeze certificate can be added to the transaction record that corresponds to the trust protocol asset, so that the freeze certificate can be used to prove the reliability of the trust protocol anchor and indicate that the trust protocol anchor trust can convert a related trust protocol asset into an asset outside the chain. As such, an association relationship between the trust protocol asset and the out-of-chain asset can support that the trust protocol asset is of real value and is not randomly issued by the trust protocol anchor. From (1306), method (1300) proceeds to (1308).
    [00114] [00114] In (1308), the trust anchor receives a redemption request from a trust member for a specific trust protocol asset. The redemption request may refer to the submission of the trustee's desire to convert the private trustee asset into an asset outside the chain. For example, the trust member you are submitting may wish to redeem the trust protocol asset in particular in the form of tokens, up to, for example, USD. From (1308), method (1300) proceeds to (1310).
    [00115] [00115] In (1310), a determination is made as to whether a freezing certificate that corresponds to the specific trust protocol asset exists in the accounting record of the trust protocol. In response to the determination that the freezing certificate that corresponds to the specific trust protocol asset exists (1312) in the trust record accounting record, method (1300) proceeds to (1314) to convert the trust protocol asset particular in an asset outside the corresponding value chain. Otherwise, in response to the determination that the freezing certificate that corresponds to the specific trust protocol asset does not exist in the trust record accounting record, method (1300) proceeds to (1316) to reject the redemption request.
    [00116] [00116] The forms of trust protocol described in this specification can dedicate an asset outside the chain to support the circulation of a trust protocol asset issued by a trust protocol anchor in the trust protocol.
    [00117] [00117] The embodiments and operations described in this specification can be implemented in digital electronic circuits, or in computer software, firmware or hardware, including the structures disclosed in this specification or in combinations of one or more of them. Operations can be implemented as operations performed by a data processing device on data stored on one or more storage devices that are readable by a computer or received from other sources. A data processing device, computer or computing device may comprise data processing devices, devices and machines, including, for example, a programmable processor, a computer, a system on a chip or several, or combinations, of the foregoing. The apparatus may include special purpose logic circuits, for example, a central processing unit (CPU), a field programmable port network (FPGA) or an application specific integrated circuit (ASIC). The device may also include code that creates an execution environment for the computer program in question, for example, code that constitutes processor firmware, a protocol package, a database management system, an operating system (for example , an operating system or a combination of operating systems), a cross-platform runtime environment, a virtual machine, or a combination of one or more of them. The device and the execution environment can carry out various infrastructures of different computing models, such as Web services, distributed computing and grid computing infrastructures.
    [00118] [00118] A computer program (also known, for example, as a program, software, software application, software module, software unit, script or code) can be written in any form of programming language, including compiled languages or interpreted, declarative or procedural languages, and can be implemented in any way, including as a stand-alone program or as a module, component, subroutine, object or other unit suitable for use in a computing environment. A program can be stored in a part of a file that contains other programs or data (for example, one or more scripts stored in a markup language document), in a single file dedicated to the program in question or in several coordinated files ( for example, files that store one or more modules, subprograms, or parts of code). A computer program can be run on one computer or on multiple computers that are located in one location or distributed in several locations and are interconnected by a communication network.
    [00119] [00119] The processors for executing a computer program include, for example, microprocessors of general and special purpose, and any one or more processors of any type of digital computer. Generally, a processor will receive instructions and data from a read-only memory or from a random access memory or both. The essential elements of a computer are a processor to perform actions according to instructions and one or more memory devices to store instructions and data. Generally, a computer will also include, or be operationally coupled to receive data from or transfer data to, or both, one or more mass storage devices for data storage. A computer can be incorporated into another device, for example, a mobile device, a personal digital assistant (PDA), a game console, a Global Positioning System (GPS) receiver or a portable storage device. Suitable devices for storing computer program instructions and data include non-volatile memory, media and memory devices, including, for example, semiconductor memory devices, magnetic disks and magneto-optical disks. The processor and memory can be supplemented by, or incorporated into special purpose logic circuits.
    [00120] [00120] Mobile devices may include micro-phones, user equipment (EU), cell phones (for example, smart phones), tablets, wearable devices (for example, smart watches and smart glasses), devices implanted within the human body (e.g., biosensors, cochlear implants) or other types of mobile devices. Mobile devices can communicate wirelessly (for example, using radio frequency (RF) signals) to various communication networks (described below). Mobile devices can include sensors to determine characteristics of the mobile device’s current environment. The sensors can include cameras, microphones, proximity sensors, GPS sensors, motion sensors, accelerometers, ambient light sensors, humidity sensors, gyroscopes, compasses, barometers, fingerprint sensors, facial recognition systems, RF sensors ( for example, cellular Wi-Fi and radio), thermal sensors, or other types of sensors. For example, cameras can include a forward or backward facing camera with movable or fixed lenses, a flash, an image sensor and an image processor. The camera can be a megapixel camera capable of capturing details for facial and / or iris recognition. The camera, together with a data processor and authentication information stored in memory or accessed remotely, can form a facial recognition system. The facial recognition system or one or more sensors, for example, microphones, motion sensors, accelerometers, GPS sensors or RF sensors, can be used for user authentication.
    [00121] [00121] To provide interaction with a user, embodiments can be implemented on a computer with a display device and an input device, for example, a liquid crystal display (LCD) or organic light-emitting diode monitor (OLED) / virtual reality (VR) / augmented reality (AR) to display information to the user and a touch screen, keyboard and an indicating device by which the user can provide data input to the computer. Other types of devices can also be used to provide interaction with a user; for example, the feedback provided to the user can be any form of sensory feedback, for example, visual feedback, auditory feedback or tactile feedback; and user input can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, sending web pages to a web browser on a user’s client device in response to requests received from the web browser.
    [00122] [00122] The embodiments can be implemented using computing devices interconnected by any form or means of wired or wireless digital data communication (or combination thereof), for example, a communication network. Examples of interconnected devices are a client and a server that are usually remote from each other and that normally interact through a communication network. A customer, for example, a mobile device, can carry out transactions itself, with a server or through a server, for example, by carrying out purchase transactions, sales, payment, delivery, delivery or loan, or by authorizing them. Such transactions can be in real time, so that an action and a response are temporarily close; for example, an individual perceives the action and the response occurring substantially simultaneously, the time difference for a response after the individual's action is less than 1 millisecond (ms) or less than 1 second (s), or the response is without delay intentional, considering the processing limitations of the system.
    [00123] [00123] Examples of communication networks include a local area network (LAN), a radio access network (RAN), a metropolitan area network (MAN) and a wide area network (WAN). The communication network can include all or part of the Internet, another communication network or a combination of communication networks. Information can be transmitted over the communication network according to various protocols and standards, including Long Term Evolution (LTE), 5G, IEEE 802, Internet Protocol (IP) or other protocols or combinations of protocols. The communication network can transmit voice, video, biometric or authentication data or other information between connected computing devices.
    [00124] [00124] Features described as separate implementations can be implemented, in combination, in a single implementation, while features described as a single implementation can be implemented in multiple implementations,
    separately or in any suitable sub-combination.
    The operations described and claimed in a specific order are not to be construed as requiring that the specific order, nor that all illustrated operations be performed (some operations may be optional). As appropriate, multitasking or parallel processing (or a combination of multitasking and parallel processing) can be performed.
