All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

The terms first, second, third (if any) and the like in the description and in the claims and in the above-described figures, are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the term "include" and any variations thereof is intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

The invention provides a blockchain resource processing method, a platform and a system, which are suitable for the method, in order to solve the technical problem that the prior user private key (namely the resource private key of a resource receiving end) cannot perform any operation on resources to be operated in a blockchain when being lost. Fig. 1 is a schematic diagram of a blockchain resource processing system according to an embodiment of the invention. The blockchain resource processing system 1000 shown in fig. 1 includes a blockchain platform 100, a resource holder 200, a resource receiver 300, and b resource monitor 400, where a and b are positive integers. Wherein,

The blockchain platform 100 has a blockchain deployed therein for storing data, such as supporting all of the resources to be operated on for the storage resource holder 200. The resources to which the present invention relates include, but are not limited to, digital assets, inherent assets, electronic red packs, and the like. Digital assets, where an enterprise or individual owns or controls, are assets that exist in the form of electronic data. The present invention takes the resource as an example of a digital asset on a blockchain, which may refer to, for example, an electronic invoice, an electronic ticket, an enterprise ticket, a supply chain finance, and the like.

The resource monitoring end 400 refers to a device for monitoring the resource receiving end 300 or the resource holding end 200, for example, monitoring the resource to be operated of the resource receiving end 300 or the resource holding end 200, for example, performing asset transfer, asset freezing, and the like. The b resource monitoring terminals 400 of the present invention support the monitoring of the a resource receiving terminals 300, and are specifically used for monitoring the corresponding resources to be operated of the resource holding terminal 200 required to be received by each of the a resource receiving terminals 300.

The resource holding end 200, the resource receiving end 300 and the resource monitoring end 400 according to the present invention may refer to devices with network communication capability, which may include, but are not limited to, internet devices such as a client, a server, a smart phone (e.g., an Android mobile phone, an IOS mobile phone, etc.), a personal computer, a tablet computer, a palm computer, a mobile internet device (mobile internet devices, MID), or a wearable smart device.

Fig. 2 is a flowchart of a blockchain resource processing method according to an embodiment of the present invention. The blockchain resource processing method is applied to the blockchain resource processing system 1000 shown in fig. 1. The invention provides a method for realizing resource transaction operation by combining a block chain technology and a multiple signature technology in order to ensure the safety of resource storage in a block chain and the legal rights and interests of both sides of resource transaction. The method as shown in fig. 2 comprises the following implementation steps:

in step S201, the resource holder 200 obtains the resource addresses of the a resource receivers 300 and the b resource monitors 400.

The resource address of the present invention may refer to an address for storing a resource, and the address may specifically refer to an address generated based on a resource public key, for example, the resource public key is processed by using a preset address generation algorithm to generate a corresponding resource address. Wherein the public and private keys are typically presented in the form of key pairs, which are typically generated by a preset key pair generation algorithm, which is a custom algorithm for generating key pairs, which may include, but is not limited to, random large prime number generation algorithms, large power modular arithmetic algorithms, and the like. The public resource key is used for generating a resource address, and the private resource key is used for decrypting the resource stored in the resource address so as to enable the resource, thereby being convenient for carrying out corresponding operation processing on the resource in the follow-up process, and the like.

Each resource terminal (specifically, the resource receiving terminal 300 or the resource monitoring terminal 400) can utilize a preset address generation algorithm and combine the resource public key thereof to generate a corresponding resource address. The address generation algorithm is a system custom set algorithm for generating addresses, which may include, but is not limited to, a blockchain address generation algorithm, a short address generation algorithm, and the like.

In step S202, the resource holder 200 sends an address generation request to the blockchain platform 100, where the request carries the resource addresses of each of the a resource receivers 300 and the b resource monitors 400. Accordingly, the blockchain platform 100 receives the address generation request.

In order to ensure the safety of the block chain resource storage, the invention introduces a multi-signature technology into the block chain, and realizes the storage of the data in the block chain by utilizing the multi-signature address. Specifically, the resource holder 200 sends an address generation request to the blockchain platform 100, where the address generation request carries the resource addresses of each of the a resource receivers 300 and the b resource monitors 400. The address generation request is used to request the blockchain platform 100 to generate a corresponding multi-signature address using the respective resource addresses of the a resource receivers 300 and the b resource monitors 400.

In step S203, the blockchain platform 100 responds to the address generation request to generate multiple signature addresses by using the respective resource addresses of the a resource receiving terminals 300 and the b resource monitoring terminals 400. The multi-signature address is used by the blockchain platform 100 to store data.

After the blockchain platform 100 receives the address generation request, the address generation request may be parsed to obtain the resource addresses of the a resource receiving ends 300 and the b resource monitoring ends 400 respectively. Further, the blockchain platform 100 performs address generation processing on the respective resource addresses of the a resource receiving ends 300 and the b resource monitoring ends 400 according to a preset address generation algorithm, so as to obtain a multi-signature address. For the address generation algorithm, reference is made to the foregoing, and details are not repeated here.

In step S204, the blockchain platform 100 sends an address generation response to the resource holder 200, where the address generation response carries the multiple signature address.

After the blockchain platform 100 allocates the multiple signature addresses to the resource holder 200, an address generation response may be fed back to the resource holder 200, where the address generation response carries the multiple signature addresses, so as to return the multiple signature addresses to the blockchain platform 100.

In step S205, the resource holder 200 sends a resource transfer request to the blockchain platform 100, where the resource transfer request is used to request that all the resources to be operated of the resource holder 200 be transferred to the multi-signature address for storage. Accordingly, the blockchain platform 100 receives the resource transfer request.

After applying for the multiple signature addresses, the resource holder 200 may send a resource transfer request to the blockchain platform 100. The resource transfer request may carry an identifier of the resource holder 200, and is used for requesting to transfer all the resources to be operated of the resource holder 200 to the multiple signature address for storage. Optionally, the resource transfer request may further carry multiple signature addresses, or other system customized information, which is not limited by the present invention.

In practice, the multi-signed address is an address generated by a multiparty private key. In the present invention, the multiple signature address is an address generated by the private keys of the a resource receiving terminals 300 and the b resource monitoring terminals 400, and there may be one or more resources to be operated of the resource holding terminal 200 under the address, and the private keys of the resources participating in the address generation according to the resource transaction rule can all operate the resources. Optionally, the invention adopts m of n multiple signature technology to realize the storage of resources in the blockchain, specifically, the multiple signature addresses are associated with n resource private keys, when the resource operation is required, the operation of corresponding resources in the multiple signature addresses can be realized by verifying and passing through the signature of m resource private keys in n.

In step S206, the blockchain platform 100 responds to the resource transfer request to transfer all the resources to be operated of the resource holder 200 to the multi-signature address storage.

In response to the resource transfer request, the blockchain platform 100 transfers all the resources to be operated of the resource holder 200 to the multi-signature address for storage, where the resources stored in the multi-signature address are accessed by a resource receivers and b resource monitors. The method comprises the steps that m resource terminals exist in a resource receiving terminal and b resource monitoring terminals, and the resource terminals can access resources stored in the multi-signature address by utilizing own resource private keys, wherein m is smaller than n, and n is the sum of a and b. And a, b, m and n are positive integers. Thereby being beneficial to ensuring the safety of the resource storage.

In step S207, the blockchain platform 100 sends a resource transfer response to the resource holder 200, wherein the resource transfer response is used to notify that all the resources to be operated of the resource holder 200 have been transferred to the multiple signature address. Accordingly, the resource holder 200 receives the resource transfer response.

Alternatively, after completion of the resource transfer, the blockchain platform 100 may send a corresponding resource transfer response to the resource holder 200 informing the resource holder 200 that the resource transfer is currently completed. At this time, all the resources to be operated of the resource holder 200 belong to a resource receivers and b resource monitors, that is, the a resource receivers and the b resource monitors can access and operate the corresponding resources to be operated of the resource holder 200 by using their own private keys.

By implementing the embodiment of the invention, the blockchain platform 100 can apply the multi-signature technology to the blockchain, and store all the resources to be operated of the resource holding end by utilizing the multi-signature address, thereby being beneficial to improving the security of the resource storage.

Fig. 3 is a flowchart of another blockchain resource processing method according to an embodiment of the present invention. The method as shown in fig. 3 comprises the following implementation steps:

step 301, the first resource terminal signs a resource operation request to be sent by using a resource private key of the first resource terminal, so as to obtain a signature request. The first resource is a resource receiving end 300 or a resource monitoring end 400.

After the blockchain platform 100 stores the resource of the resource holding end 200 to the multiple signature address by using the multiple signature technology, if the corresponding resource to be operated stored in the multiple signature address needs to be operated, the corresponding resource to be operated in the multiple signature address needs to be started by using the private key signature of the respective resource of the m first resource ends, so as to perform operations such as resource transfer and the like. The m first resource terminals belong to resource terminals in the a resource receiving terminals 200 and the b resource monitoring terminals 300, and specifically, the first resource terminals may be the resource receiving terminals 200 or the resource monitoring terminals 300. The following describes how the first resource end implements the operation for the corresponding resource to be operated of the resource holder 200 in the multiple signature address, taking a first resource end as an example. Specifically:

The first resource terminal signs the resource operation request to be sent by utilizing the private key of the first resource terminal to obtain a corresponding signature request. The first resource then sends the signature request to the blockchain platform 100. After receiving the signature request of the first resource, the blockchain platform 100 may perform signature decoding and signature verification on the signature request of the first resource by using the resource public key of the first resource, and after verification is successful, correspondingly obtain the resource operation request of the first resource. The specific embodiment of how to verify the signature request based on the resource public key is not limited.

For example, taking a public resource key and a private resource key as a symmetric key pair as an example, the signature request of the first resource end carries the resource operation request of the first resource end and the signature data of the resource operation request. Accordingly, after the blockchain platform 100 receives the signature request of the first resource, the public key of the first resource may be used to encrypt the resource operation request of the first resource to obtain verification data. And then judging whether the verification data is the same as the received signature data, if so, determining that the signature request of the blockchain platform 100 on the first resource terminal is successful in verification. Otherwise, it is determined that the blockchain platform 100 fails to verify the signature request of the first resource.

In step S302, the m first resource ends send the signature requests to the blockchain platform 100. Accordingly, the blockchain platform 100 receives signature requests of m first resource ends, where the m first resource ends include one or more resource monitor ends 400. Accordingly, the blockchain platform 100 receives signature requests of m first resource ends.

Step 303, the blockchain platform 100 parses and verifies the signature requests of the m first resource ends.

In step S304, after the signature verification of the signature request of the m first resource ends is successful, the blockchain platform 100 obtains resource operation requests of the m first resource ends.

In the multiple signature technology, in order to realize the operation processing of the corresponding resources to be operated in the multiple signature address, the blockchain platform needs to acquire m private key signatures of the resources so as to complete authority verification and then can operate the corresponding resources in the multiple signature address. In particular, in the present invention, a plurality of first resource ends may send respective signature requests to the blockchain platform, where the number of the first resource ends needs to be more than m. After signing the signature request of m first resource ends in the plurality of first resource ends, the blockchain platform 100 may obtain respective resource operation requests of the m first resource ends, and further respond to the resource operation request of any one of the m first resource ends.

For example, the present invention takes the example that m first resource ends send respective signature requests to the blockchain platform 100, where the signature requests are obtained by signing the resource operation requests by the first resource ends with their own private keys. The blockchain platform 100 receives signature requests of the m first resource ends, and in particular, the blockchain platform 100 may receive the signature requests sent by the m first resource ends respectively according to a time sequence. The blockchain platform 100 further performs signature verification processing on the signature requests of the m first resource ends. After all signature verification of the signature requests of the m first resource ends is successful, the blockchain platform 100 may respond to the resource operation requests of any or all of the m first resource ends correspondingly.

In step S305, the blockchain platform 100 responds to the resource operation request of the second resource end, and performs the resource operation process requested by the resource operation request on the corresponding resource to be operated of the resource holding end 200. The second resource is the resource monitor 400 of the m first resource.

After all signature verification of the signature requests of the m first resource ends succeeds, the blockchain platform 100 indicates that the blockchain platform 100 has the authority of operating (such as accessing and transferring) all the resources to be operated stored in the multiple signature addresses. Further alternatively, the blockchain platform 100 may respond to a resource operation request from a second resource, where the second resource is any one or more of the m first resource, and in particular may be a resource receiving end. In particular, the second resource is embodied as one or more resource monitor ports 400 among the m first resource ports. If the second resource end is the resource monitoring end 400, the resource monitoring end 400 can complete the operation processing of the corresponding resource to be operated by sending a signature request carrying the resource operation request to the blockchain platform 100 without participation of the resource receiving end 300. The situation that when the resource private key (namely the user private key) of the resource receiving end 300 is lost, the corresponding resource to be operated on the blockchain cannot be operated is avoided.

Several embodiments relating to step S305 are described below.

In one embodiment, if the resource operation request is a resource transfer request, the resource transfer request carries a resource address of the target receiving end. The resource address of the target receiving end is self-defined by the second resource end, for example, the resource address of the second resource end, or the resource address of any resource receiving end appointed by the second resource end, etc.

Accordingly, the blockchain platform 100 can respond to the resource transfer request of the second resource end, and transfer the corresponding to-be-operated resource of the resource holding end 200 in the multiple signature address from the multiple signature address to the resource address storage of the target receiving end, so that the resource transfer can be completed without participation of the target receiving end, and the problems that the private key of the resource receiving end is lost and the operation on the resource on the blockchain can not be performed any more are avoided under the condition of ensuring the safety of the resource transfer. The target receiving end is a receiving end which is supervised by a second resource end (resource supervision end) in the a resource receiving ends.

For example, assume a blockchain resource processing system 1000 includes a blockchain platform, a resource holder, 10 resource receivers, and 2 resource monitors. The resource receiving terminals 1 to 5 are respectively monitored by the resource monitoring terminal 1, and the resource receiving terminals 6 to 10 are respectively monitored by the resource monitoring terminal 2. The resource holder 200 has 100 tens of thousands of digital assets stored in multiple signature addresses on the blockchain, which are generated from the respective resource addresses of 10 resource receivers and 2 resource supervisors. If the resource holder 200 needs to transfer 100 tens of thousands of digital assets to 10 resource receivers on average. The example can be seen as follows: the resource monitoring end 1 monitors 10 ten thousand digital assets of each of the resource receiving ends 1 to 5. The resource monitoring end 2 monitors 10 ten thousand digital assets of each of the resource receiving ends 6 to 10.

In the multiple signature technology of 2 of 12, if the blockchain platform receives signature requests sent by 2 resource supervision ends respectively and successfully tests the signature requests, the blockchain platform can obtain the resource transfer requests of the 2 resource supervision ends respectively. The resource transfer request of the resource monitoring end 1 carries respective resource addresses (also referred to as transaction addresses) of the resource receiving ends 1 to 5, and is used for requesting to transfer 10 ten thousand digital assets of the resource holding ends for the 5 resource receiving ends respectively. The resource transfer request of the resource monitoring end 2 carries respective resource addresses of the resource receiving ends 6 to 10, and is used for requesting to transfer 10 ten thousand digital assets of the resource holding ends for the 5 resource receiving ends respectively.

Correspondingly, the blockchain platform can respond to the resource transfer request of the resource monitoring end 1 to transfer the digital assets of the resource holding end stored in the multiple signature addresses to the respective resource addresses of the resource receiving ends 1-5 respectively. Similarly, the blockchain platform can respond to the resource transfer request of the resource monitoring end 2 to transfer the digital assets of the resource holding end stored in the multiple signature addresses to the respective resource addresses of the resource receiving ends 6-10 respectively.

In yet another embodiment, the resource operation request is a resource update request, which is used to request to update the corresponding resource to be operated of the resource holder. And correspondingly, the blockchain platform responds to a resource updating request of the second resource end to update the corresponding resource to be operated of the resource holding end stored in the multi-signature address. For example, the resource type of the corresponding resource to be operated, the effective time of the resource storage, the size of the resource, or other customized resource information is updated, and the invention is not limited.

In yet another embodiment, the resource operation request is a resource borrowing request, where the resource borrowing request carries a resource address of a resource borrowing end. Correspondingly, the blockchain platform can respond to the resource borrowing request of the second resource end, borrow the corresponding resource to be operated of the resource holding end in the multi-signature address and transfer the resource to the resource borrowing end, and particularly can transfer the resource to the resource address of the resource borrowing end. Optionally, the blockchain platform may further record corresponding resource borrowing information, where the resource borrowing information is used to instruct the second resource end to borrow the corresponding resource to be operated to the resource borrowing end.

For example, referring to the above example of the blockchain resource processing system 1000 including a blockchain platform, a resource holding end, 10 resource receiving ends and 2 resource monitoring ends, assuming that the resource receiving end 1 needs to borrow 10 ten thousand digital assets to the resource borrowing end corresponding to the user a, the resource receiving end 1 itself or the resource receiving end 1 sends a resource borrowing request to the blockchain platform through the monitored resource monitoring end 1. The second resource end is taken as the resource monitoring end 1 to describe how to implement resource borrowing. The resource borrowing request is used for indicating that 10 ten thousand digital assets of the resource receiving end 1 are borrowed to the resource borrowing end. The resource borrowing request carries a resource address of the resource borrowing end.

And correspondingly, after the block chain platform receives the resource borrowing request of the resource monitoring end 1, the 10 ten thousand digital assets of the resource holding end stored in the multi-signature address can be borrowed and transferred to the resource borrowing end in response to the resource borrowing request, and the resource borrowing end does not need to be determined through the resource receiving end 1, so that the operation is convenient. Optionally, after the resource monitoring terminal 1 finishes borrowing the corresponding asset to be operated, a response message may be sent to the resource receiving terminal 1, for notifying that 10 ten thousand digital assets of the resource receiving terminal 1 have been successfully borrowed and transferred to the resource borrowing terminal.

In yet another embodiment, the resource operation request is a resource deactivation request, where the resource deactivation request is used to indicate to deactivate a corresponding resource to be operated on by the resource holder. Specifically, the blockchain platform may respond to the resource disabling request of the second resource end, and freeze the corresponding resource to be operated of the resource holding end in the multiple signature address, so as to close the access right for the corresponding resource to be operated and disable the corresponding resource to be operated.

For example, referring to the blockchain resource processing system 1000, the blockchain platform, the resource holder, 10 resource receivers, and 2 resource monitor, the second resource monitor 1 are shown. The resource monitoring end 1 sends a resource disabling request to the blockchain platform, where the disabling request is specifically configured to request to disable the corresponding digital asset of the resource holder monitored by the resource monitoring end 1 itself, and in this example, the disabling of the corresponding digital asset of the 10 ten thousand digital assets of each of the monitoring resource receiving ends 1 to 5, that is, the disabling of the 50 ten thousand digital asset of the resource holder may be specifically referred to.

Correspondingly, after the blockchain platform receives the resource disabling request of the resource monitoring end 1, the blockchain platform can respond to the resource disabling request to freeze the 50 ten thousand digital assets of the resource holding end stored in the multi-signature address, and specifically the 10 ten thousand digital assets to be transferred to the resource receiving ends 1-5. For frozen digital assets, the resource receiving end and the resource monitoring end have no right to reuse the frozen digital assets, and the frozen digital assets need to be normally started and operated after being thawed.

In still another embodiment, the resource operation request is a resource enabling request, and the corresponding resource to be operated of the resource holder is the frozen corresponding resource to be operated. Accordingly, the blockchain platform can respond to the resource enabling request of the second resource end to unfreeze the corresponding resource to be operated of the frozen resource holding end in the multi-signature address so as to restore the use authority of the corresponding resource to be operated, for example, the corresponding resource to be operated can be enabled, and the corresponding resource to be operated can be subjected to operation processes such as transferring, updating and the like.

For example, referring to the above example of the resource deactivation request, if the corresponding resource to be operated on by the resource holder is frozen, if the corresponding resource to be operated is to be reused, it is required to defrost the corresponding resource to be operated on. In this example, if the resource monitoring end 1 or the 5 resource receiving ends monitored by the resource monitoring end 1 want to start the corresponding resources to be operated of the resource holding end again, the resource monitoring end 1 may send a resource start request to the blockchain platform, for requesting to defrost 10 ten thousand digital assets of each of the 5 resource receiving ends, so as to start the 50 ten thousand digital assets.

Correspondingly, the blockchain platform receives a resource starting request of the resource monitoring end 1, and responds to the resource starting request to defrost 50 ten thousand digital assets of the resource holding end after being frozen in the multi-signature address, and specifically, the thawing process can be performed on 10 ten thousand digital assets of each of the resource receiving ends 1-5. The subsequent resource monitoring end 1 and the resource receiving ends 1-5 can conveniently utilize their own private key signatures to operate corresponding digital assets, such as asset transfer.

It should be noted that the present invention is applied to a blockchain scenario, and in particular, may be applied to a blockchain electronic invoice, an electronic ticket, a supply chain finance, a digital asset, or other scenarios requiring digital asset supervision, etc., and the present invention is not limited thereto.

By implementing the invention, the multi-signature technology can be applied to the blockchain, thereby not only ensuring the safety of the storage of resources in the blockchain, but also solving the technical problem that the resources in the blockchain cannot be operated after the resource receiving end (user private key) is lost in the prior art.

To aid in better understanding of the present invention, a blockchain resource processing system, also referred to as a blockchain asset processing system, is described below by taking a digital asset as an example, and includes 1 blockchain platform, asset holding side, asset receiving side, and asset monitoring side, where a=b=1. And, the blockchain platform adopts a 1 of 2 multiple signature technology to realize the storage of the digital asset. Fig. 4 is a flowchart of another blockchain asset processing method according to the present invention. As shown in fig. 4, the resource operation process is specifically, but not limited to, an asset transfer process, and the method includes the following implementation steps:

In step S401, the asset holding end sends an address generation request to the blockchain platform, where the request carries the asset addresses of the asset receiving end and the asset monitoring end. Accordingly, the blockchain platform receives the address generation request.

The asset holding end needs to acquire the respective asset addresses of the asset receiving end and the asset monitoring end, and the asset addresses can be acquired actively by the asset holding end or can be received passively and sent by other devices. For example, the asset holding end may send an address acquisition request to the asset receiving end and the asset monitoring end, respectively, to be applied to acquire the asset address of the asset receiving end and the asset address of the asset monitoring end. The description of the asset address in the foregoing embodiments is specifically referred to, and will not be repeated here.

Further, the asset holder may send an address generation request to the blockchain platform requesting allocation of the multi-signed address for storing the digital asset of the asset holder.

In step S402, the blockchain platform returns an address generation response to the asset holding end in response to the address generation request, where the address generation response carries a multiple signature address, where the multiple signature address is generated by using the asset addresses of the asset receiving end and the asset monitoring end.

The block chain platform receives the address generation request, and analyzes the address generation request to obtain the asset address of the asset receiving end and the asset address of the asset monitoring end. And responding to the address generation request, and adopting a preset address generation algorithm to generate the addresses of the assets of the asset receiving end and the asset monitoring end so as to obtain multiple signature addresses. Accordingly, the blockchain platform returns an address generation response to the asset holder, wherein the address generation response carries the multiple signature address, so that the multiple signature address is returned to the asset holder.

Step S403, the asset holder sends a first asset transfer request to the blockchain platform, the first asset transfer request requesting that the asset holder transfer the asset to the multi-signature address for storage. The blockchain platform receives the asset transfer request accordingly.

Step S404, the blockchain platform returns a first asset transfer response to the asset holder, the first asset transfer response being used to inform that the asset of the asset holder has been transferred to the multi-signed address store.

After receiving the first asset transfer request, the blockchain platform may transfer the asset of the asset holder to the multi-signature address store in response to the first asset transfer request. Optionally, the blockchain platform may also return an asset transfer response to the asset holder for informing the asset holder that its own asset has been transferred to storage in the multi-signed address. At this time, the asset receiving end and the asset monitoring end can operate on the asset stored in the multiple signature addresses by using their own private keys.

Step S405, the asset monitoring end sends a signature request to the blockchain platform, wherein the signature request is obtained by signing the second asset transfer request by using the asset private key of the asset monitoring end. The blockchain platform receives the signature request accordingly.

Step S406, after the signature request is successfully checked, the blockchain platform responds to a second asset transfer request and returns a second asset transfer response to the asset monitoring end, wherein the second asset transfer response is used for informing that the asset of the asset holding end has been transferred to the designated asset address. The specified asset address is an address which is custom-specified by the resource monitoring end and is used for receiving the asset, such as a transaction address of the asset receiving end.

After receiving the signature request, the blockchain platform of the invention carries the second asset transfer request and signature data aiming at the request. The signature request may be further parsed and the signature request may be validated or verified, after which a second asset transfer request may be obtained, with respect to the validation of the signature request, as described in more detail in the previous embodiments. In practical applications, the second asset transfer request carries a specified asset address, and the present invention is described below with reference to a transaction address of the asset receiving end as an example.

The blockchain platform can respond to the second asset transfer request to transfer the asset of the asset holding end from the multiple signature address to the transaction address of the asset receiving end, and the asset transaction can be completed without confirmation by the asset receiving end, so that the efficiency of asset processing is improved. By implementing the embodiment of the invention, the efficiency of asset processing is improved, and the technical problems that the operation of the assets on the block chain cannot be performed any more due to the loss of the private key of the user at the receiving end of the existing assets are solved.
