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.

In order to solve the problems that in the prior art, after a user private key of a resource receiving end is lost, resources on a blockchain cannot be operated, and the resources on the blockchain are easy to be stored for a long time and are not used. The invention provides a block chain resource processing method, a platform, a system and a computer readable storage medium, wherein the platform, the system and the computer readable storage medium are applicable to the method. 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 resources for storing the resource holders 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 digital assets such as electronic invoices, electronic tickets, business tickets, supply chain finance or other customizations, and the like.

Resource monitoring end 400 refers to a device for monitoring resource receiving end 300 or resource holding end 200, for example, monitoring the corresponding resource of each of resource receiving end 300 or resource holding end 200, such as performing asset transfer, asset freezing, etc. 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 of the resource holding terminals 200 that the a resource receiving terminals 300 need to receive.

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 method provides that the multi-signature technology is combined in the blockchain to realize the safe storage of the resource at the resource holding end. 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 generate a corresponding resource address by utilizing a preset address generation algorithm and combining the resource public key of the resource terminal. 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 original multi-signature address (hereinafter referred to as the original multi-signature address) by using the 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 the original multiple signature address by using the respective resource addresses of the a resource receiving terminals 300 and the b resource monitoring terminals 400. The original 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 an original multiple 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 original multiple signature address.

After the blockchain platform 100 allocates the original multiple signature address 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 original multiple signature address, so as to return the original multiple signature address 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 to transfer the resource of the resource holder 200 to the original multi-signature address for storage. Accordingly, the blockchain platform 100 receives the resource transfer request.

After applying for the original multi-signed address, 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 the resource of the resource holder 200 to the original multiple signature address for storage. Optionally, the resource transfer request may also carry an original multiple signature address, or other system customized information, which is not limited by the present invention.

In practical applications, the original multi-signed address is an address generated by a multiparty private key. The original multiple signature address is an address generated by the private keys of the a resource receiving ends 300 and the b resource monitoring ends 400, and one or more resources of the resource holding ends 200 may exist under the address, and the private keys of the resources participating in the address generation according to the resource transaction rule can operate the resources. Optionally, the invention adopts m of n multiple signature technology to realize the storage of resources in the blockchain, specifically, the original multiple signature address is associated with n resource private keys, when the resource operation is required, the verification can be carried out by signing by using m resource private keys in n, and the operation of corresponding resources in the multiple signature address is realized, and the invention is specifically described in detail below.

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

The blockchain platform 100 responds to the resource transfer request to transfer the resources of the resource holding end 200 to the original multi-signature address for storage, and at this time, the resources stored in the original multi-signature address are accessed by a resource receiving ends and b resource monitoring ends. 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 original multiple signature addresses 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 the resource of the resource holder 200 has been transferred to the original multi-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 holding end 200 belong to a resource receiving ends and b resource monitoring ends, that is, the a resource receiving ends and the b resource monitoring ends can access and operate the resources of the resource holding end 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 the multi-signature address is utilized to store the resource of the resource holding end, so that the security of the resource storage is improved.

In practical application, if the private key of the resource at the resource receiving end is lost, the operation on the resource on the blockchain cannot be performed through the private key. For this reason, please refer to fig. 3, which is a flowchart illustrating 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 target monitor end obtains a new resource address of the first receiving end, where the new resource address is generated based on a new private key of the first receiving end. The target monitoring end is one of the b resource monitoring ends, and the first receiving end is one of the a resource receiving ends which is monitored by the target monitoring end.

The new resource address of the first receiving end is generated according to the new private key of the first receiving end, and specifically, the new resource address of the first receiving end can be obtained by adopting a preset address generation algorithm to generate the address of the new private key of the first receiving end. In practical applications, the new resource address of the first receiving end may be specifically generated at the first receiving end side or the target monitoring end side, which is not limited by the present invention. Taking the generation of the target monitoring end as an example, the target monitoring end needs to acquire a new private key of the first receiving end, and then uses a preset address generation algorithm to perform address generation on the new private key of the first receiving end to obtain a new resource address of the first receiving end. For the address generation algorithm, reference may be made specifically to the relevant description in the foregoing embodiments, and details are not repeated here. The number of the first receiving ends is not limited, and may be one or more, and the present invention is described below with reference to a first receiving end as an example.

After the first receiving end loses the original private key (also called as the original resource private key), a new resource key pair can be generated for the first receiving end according to a preset key generation algorithm, and the new resource key pair can specifically comprise a new private key and a new public key of the first receiving end. The pre-key generation algorithm may be system-custom set, which may include, but is not limited to, a digital signature algorithm (digital signature algorithm, DSA), an advanced encryption standard (advanced encryption standard, AES) algorithm, and the like.

Accordingly, the specific embodiment of the target monitor terminal obtaining the new private key of the first receiving terminal is not limited. For example, the first receiving end may actively send the new private key of the first receiving end to the target monitoring end. Or after determining that the first receiving end loses the resource private key, the target monitoring end can acquire the new private key of the first receiving end from the first receiving end, for example, by sending a private key acquisition message to the first receiving end so as to acquire the new private key of the first receiving end. The target supervision terminal is a supervision terminal used for supervising the first receiving terminal in the b resource supervision terminals. In this way, even if the first receiving end loses the private key of the resource, the new private key can be utilized to realize the re-storage and re-use of the resource, and the target monitoring end which is regulated by the new private key applies for the new multi-signature address of the re-allocation resource storage, and the new multi-signature address is specifically described in detail in the following description of the invention.

In step S302, the target monitor end sends an address re-request to the blockchain platform 100, where the address re-request carries the new resource address of the first receiving end. Accordingly, the blockchain platform 100 receives the address re-request.

The first receiving end loses the original resource private key, so that the first receiving end does not have the right to operate the resources stored in the original multiple signature addresses in the block chain. If the operation authority of the first receiving end on the resources on the blockchain needs to be restored, the storage address of the resources on the blockchain needs to be migrated again. Specifically, the target monitor end may send an address re-request to the blockchain platform 100 requesting that the resource of the resource holder be re-allocated a new multi-signed address.

The address re-request carries a new resource address of the first receiving end, so that the blockchain platform 100 can conveniently allocate a new multiple signature address by using the new resource address. Optionally, the address re-request may further carry the resource addresses of the b resource monitor ends and the resource addresses of the a resource receivers except the first receiver under the condition that the resource overhead is not considered. Since the blockchain platform 100 has obtained these resource addresses when the blockchain platform 100 allocates the original multiple signature addresses, the address re-request may only carry the new resource address of the first receiver in consideration of the resource overhead.

In step S303, the blockchain platform 100 responds to the address re-request to generate a new multi-signature address by using the new resource address of the first receiving end, where the new multi-signature address is used to store the resource of the resource holder.

After the blockchain platform 100 receives the address re-request, a preset address generation algorithm may be adopted to generate an address for the new resource address of the first receiving end, the resource addresses of the b resource monitoring ends, and the resource addresses of the other receiving ends except the first receiving end in the a resource receiving ends, so as to obtain a new multiple signature address. The new multi-signature address is used to store the resource of the resource holder.

In step S304, the blockchain platform 100 returns the new multiple signature address to the target monitor terminal.

After the blockchain platform 100 obtains the new multiple signature address, it may feed it back to the target monitor end. Specifically, the blockchain platform 100 may send an address re-response to the target monitor, where the address re-response carries a new multiple signature address, so as to feed back the new multiple signature address to the target monitor.

Optionally, following step S304, the following implementation steps may be further included, as shown in fig. 4. Fig. 4 is a flowchart of another blockchain resource processing method according to an embodiment of the invention. The method shown in fig. 4 specifically includes:

And step S401, the first resource terminal signs the resource operation request to be sent by using the resource private key of the first resource terminal to obtain a first signature request. The first resource end is a resource receiving end or a resource monitoring end.

In step S402, the m first resource ends send respective first signature requests to the blockchain platform 100. Accordingly, the blockchain platform 100 receives the first signature requests of the m first resource ends. The m first resource ends comprise target monitoring ends.

After the blockchain platform 100 stores the resource of the resource holder to the original multiple signature address by using the multiple signature technology, if the resource of the resource holder needs to be operated, the operation, such as resource transfer, can be performed on the resource in the original multiple signature address by using the private key signature of each of the m first resource ends. The m first resource ends are resource ends in a resource receiving ends and b resource monitoring ends.

Therefore, the blockchain platform can realize the corresponding operation of the resource, such as resource transfer and the like, after the signature verification of the resource private key signature of at least m first resource ends is successful. Taking a first resource end as an example, the first resource end signs a resource operation request to be sent by utilizing a self resource private key 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 practice, the resource operation request includes, but is not limited to, a resource transfer request, a resource deactivation request, a resource activation request, a resource borrowing request, or other customized resource operation request, etc.

Step S403, the blockchain platform 100 performs signature verification on the m first signature requests.

In step S404, after the signing success of the m first signature requests, the blockchain platform 100 obtains resource operation requests of the m first resource ends. The resource operation requests of the m first resource ends comprise first resource transfer requests of the target receiving end.

After receiving the m first signature requests, the blockchain platform 100 may perform signature verification on the m first signature requests, and after the signature verification is successful, may obtain resource operation requests of the m first resource ends. And further responds to the resource operation request of any one or more of the m first resource ends. The resource operation request is executed to correspond to the operation processing of the corresponding resource requested.

In step S404, the blockchain platform 100 responds to the first resource transfer request of the target monitor terminal to transfer the corresponding resource of the resource holder terminal from the original multi-signature address to the new multi-signature address for storage.

In the present invention, the m first resource ends include a target monitor end, and the resource operation request of the target monitor end may specifically be a first resource transfer request of the target monitor end. The request is for requesting a transfer of the resource at the resource holder from the original multi-signed address to a new multi-signed address for storage. Taking the first resource transfer request of the blockchain platform 100 in response to the target monitor end as an example, the blockchain platform 100 transfers the resource of the resource holder from the original multi-signed address to the new multi-signed address in response to the first resource transfer request. At this time, the first receiving end can use its own new private key to operate the resource of the storage resource holding end in the new multiple signature address, i.e. the first receiving end has the authority to operate the resource in the blockchain.

In step S405, the blockchain platform 100 sends a first resource transfer response to the target supervision peer, where the first resource transfer response is used to notify that the resource of the resource holder has been successfully transferred to the new multi-signature address for storage.

After the blockchain platform 100 completes the resource operation request of any first resource end, a corresponding resource operation response may be returned to the first resource end, where the resource operation response is used to notify that the operation processing of the corresponding resource requested by the resource operation request is currently completed. Specifically, taking the example of executing the first resource transfer request, the blockchain platform 100 may send a first resource transfer response to the target supervision terminal after completing the resource transfer requested by the first resource transfer request, where the response is used to notify that the resource of the resource holder terminal has been successfully transferred to the new multi-signature address for storage.

It is understood that, when m=1, the 1 first resource end may be specifically the target monitor end. Correspondingly, the specific implementation of steps S401 to S405 in the present invention may be: the blockchain platform 100 receives a first signature request sent by a target monitoring end, and obtains a first resource transfer request after the first signature request is checked successfully. The method further comprises the step of transferring the resource of the resource holding end from the original multi-signature address to a new multi-signature address for storage in response to the first resource transfer request. Optionally, the blockchain platform 100 may also return a first resource transfer response to the target monitor peer, where the response is used to inform the target monitor peer that the resource of the resource holder has been successfully transferred to the new multi-signed address for storage.

Fig. 5 is a flowchart of another blockchain resource processing method according to an embodiment of the present invention. The method shown in fig. 5 specifically comprises the following implementation steps:

And step S501, the second resource terminal signs the resource operation request to be sent by using the resource private key of the second resource terminal to obtain a second signature request. The second resource end is a resource receiving end or a resource monitoring end.

In step S502, the m second resource ends send respective second signature requests to the blockchain platform 100. Accordingly, the blockchain platform 100 receives the second signature requests of the m second resource ends. The m second resource ends include a target resource end, which may specifically refer to a first receiving end or a target monitoring end.

In step S503, after the second signature request of the m second resource ends is successfully checked, the blockchain platform 100 obtains resource operation requests of the m second resource ends. The resource operation requests of the m second resource ends comprise second resource transfer requests of the target resource end, which are used for requesting to transfer corresponding resources of the resource holding end to a designated resource address, for example, a new resource address of the first receiving end for storage.

The descriptions of steps S501 to S503 may be specifically referred to the related descriptions of steps S401 to S403, and the present invention is not described in detail herein. The m second resource ends include a target resource end, which may be specifically a first receiving end or a target monitoring end for monitoring the first receiving end. The resource operation request of the target resource end may be specifically a second resource transfer request, which is used for requesting to transfer the corresponding resource of the resource holding end to a specified resource address, where the specified resource address may be specifically a target resource end custom address, for example, a new resource address of the first receiving end, etc. If the specified resource address is a new resource address of the first receiving end, the second resource transfer request is specifically used for requesting to transfer the corresponding resource of the resource holding end to the first receiving end, and specifically to the new resource address of the first receiving end.

In step S504, the blockchain platform 100 responds to the second resource transfer request of the target resource end to transfer the corresponding resource of the resource holding end from the new multiple signature address to the new resource address of the first receiving end for storage.

In step S505, the blockchain platform 100 sends a second resource transfer response to the target resource, where the response is used to notify that the corresponding resource of the resource holder has been successfully transferred to the new resource address of the first receiving end for storage.

The blockchain platform 100 may optionally also send a second resource transfer response to the target resource after executing the second resource transfer request. The second resource transfer response is used for notifying that the resource of the resource holding end is transferred to the first receiving end currently. When the target resource end is the target monitoring end, the transfer of the corresponding resource can be completed without confirmation by the first receiving end by implementing the flow, thereby being beneficial to improving the efficiency of resource transfer.

Similarly, when m=1, the 1 second resource may be specifically the target resource. Correspondingly, the specific implementation of steps S501 to S505 in the present invention may be: the blockchain platform 100 receives a second signature request sent by the target resource end, and obtains a second resource transfer request of the target resource end after the second signature request is checked successfully. And further responding to the second resource transfer request, and transferring the resource of the resource holding end from the new multi-signature address to the new resource address of the first receiving end for storage.

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.

The block chain platform of the embodiment of the invention receives the address re-request sent by the target monitoring end, so as to regenerate a new multi-signature address by utilizing a new resource address of a first receiving end in the request, wherein the new multi-signature address is used for storing resources of a resource holding end, and the new resource address of the first receiving end is generated based on a new private key of the first receiving end. Therefore, even if the first receiving end loses the old private key, the new private key can be reused to reconfigure the new multi-signature address so as to store the resource of the resource holding end, and the first receiving end can operate the resource by using the new private key. The method and the device solve the problems that in the prior art, after a user private key of a receiving end is lost, the operation of resources on a blockchain can not be carried out, and the resources on the blockchain are sealed for a long time and are not used.

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 1of 2 multiple signature technology to realize the storage of the digital asset. Fig. 6 is a flowchart of another blockchain resource processing method according to the present invention. The method as shown in fig. 6 comprises the following implementation steps:

In step S601, the asset holding end sends an address generation request to the blockchain platform, where the address generation request carries respective asset addresses of the asset receiving end and the asset monitoring end. The blockchain platform receives the address generation request accordingly.

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 from other equipment (such as the asset receiving end or the asset monitoring end) and the like.

Further, the asset holding end can encapsulate the respective asset addresses of the asset receiving end and the asset monitoring end into an address generation request, and then send the address generation request to the blockchain platform. The address generation request is used for requesting the blockchain platform to allocate an original multiple signature address for the asset of the asset holder so as to store the asset of the asset holder by using the original multiple signature address, thereby improving the security of asset storage.

And step S602, the blockchain platform returns an address generation response to the asset holding end in response to the address generation request, wherein the address generation response carries the original multiple signature address. The original multiple signature addresses are generated by utilizing the respective asset addresses of the asset receiving end and the asset monitoring end.

After receiving the address generation request, the block chain platform responds to the address generation request and performs address generation processing on the respective asset addresses of the asset receiving end and the asset monitoring end by using a preset address generation algorithm to obtain the original multiple signature address. Further blockchain platforms may return the original multi-signed address to the asset holder.

Step S603, the asset holder sends a first asset transfer request to the blockchain platform, wherein the first asset transfer request is used for requesting to transfer the asset of the asset holder to the original multi-signature address for storage. The blockchain platform receives the first asset transfer request accordingly.

After the asset holding end obtains the original multiple signature address, the asset holding end can further send a first asset transfer request to the blockchain platform. The first asset transfer request is for requesting transfer of an asset at an asset holder to an original multi-signature address for storage. The blockchain platform receives the first asset transfer request and responds to transfer the asset of the asset holding end to the original multi-signature address for storage, so that the safety of asset storage is improved.

Step S604, 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 original multi-signature address store.

The blockchain platform may feed back a first asset transfer response to the asset holder upon completion of the first asset transfer request. The first asset transfer response is used to inform the asset holder that the asset holder has been successfully transferred to the original multi-signature address for storage.

Step S605, the asset receiving end generates a new asset address of the asset receiving end by using the new private key of the asset receiving end, and sends the new asset address to the asset monitoring end. Accordingly, the asset monitoring end receives the new asset address of the asset receiving end.

According to the invention, under the condition that the original private key is lost by the asset receiving end, the asset receiving end can regenerate the new private key of the asset receiving end by utilizing a preset key generation algorithm. The asset receiving end can generate a new asset address of the asset receiving end by using a preset address generation algorithm and a new private key of the asset receiving end. Further, the asset receiving end can send the new asset address to the asset monitoring end. The asset monitoring end is similar to a trusted third party platform and is used for a mechanism or organization for carrying out safety supervision on the assets of the asset receiving end.

In step S606, the asset monitor end sends an address re-request to the blockchain platform, where the address re-request carries a new asset address of the asset receiver and is used for requesting to reassign a new multiple signature address. The blockchain platform receives the address re-request accordingly.

After the asset monitoring end obtains the new asset address of the asset receiving end, an address re-request can be sent to the blockchain platform. The address re-request is used to request the blockchain platform to re-assign a new multi-signed address to the asset at the asset holder. The address re-request carries the new asset address of the asset receiving end. Optionally, the address re-request may also carry an asset address of the asset monitoring end, or other system customized information, etc., which is not limited by the present invention.

Step S607, the blockchain platform returns a new multiple signature address to the asset monitoring end.

After receiving the address re-request, the blockchain platform can respond to the address re-request and generate a new multiple signature address by utilizing the new asset address of the asset receiving end and the asset address of the asset monitoring end. The blockchain platform returns the new multi-signature address to the asset monitoring end. Specifically, the blockchain platform may send an address re-response to the asset monitoring end, where the address re-response carries a new multiple signature address, so as to return the new multiple signature address to the asset monitoring end.

In step S608, the asset monitoring end sends a first signature request to the blockchain platform, where the first signature request is obtained by signing the first asset transfer request with the asset private key of the asset monitoring end. The blockchain platform receives a first signature request accordingly.

After the blockchain platform reassigns the new multiple signature address, the asset monitoring end may send a first signature request to the blockchain platform, where the first signature request is specifically obtained by the asset monitoring end signing the first asset transfer request with its own asset private key. The first asset transfer request is for requesting transfer of an asset at an asset holder to a new multi-signature address.

Step S609, the blockchain platform obtains a first asset transfer request after the first signature request is checked successfully. In response to the first asset transfer request, a first asset transfer response is returned to the asset monitor end, the response being used to inform that the asset of the asset holder has been transferred from the original multi-signed address to the new multi-signed address.

The blockchain platform receives the first signature request and performs signature verification on the first signature request. After the verification is successful, a first asset transfer request may be obtained. And further responding to the first asset transfer request, transferring the asset of the asset holding end from the original multi-signature address to a new multi-signature address, so that the asset receiving end can use the new private key to operate the asset stored in the new multi-signature address.

After the first asset transfer request is executed, the blockchain platform can send a first asset transfer response to the asset monitoring end, wherein the first asset transfer response is used for informing the asset monitoring end that the asset of the asset holding end is transferred to a new multi-signature address storage currently.

In step S610, the asset receiving end sends a second signature request to the blockchain platform, where the second signature request is obtained by signing the second asset transfer request with a new private key of the asset receiving end. The blockchain platform receives the second signature request accordingly.

After the blockchain platform transfers the asset of the asset holding end to the new multiple signature address, the asset receiving end can use the new private key of the asset receiving end to perform corresponding operation on the asset. For example, the asset receiving end may sign the second asset transfer request to be sent with the new private key of the asset receiving end to obtain a second signed request. The second signature request is then sent to the blockchain platform.

Step S611, the blockchain platform obtains a second asset transfer request after the second signature request is checked successfully. And returning a second asset transfer response to the asset receiving end in response to the second asset transfer request, the response being used for notifying that the asset of the asset holding end has been transferred from the new multiple signature address to the new asset address of the asset receiving end for storage.

And correspondingly, after the blockchain platform receives the second signature request, the second signature request can be checked, and after the check is successful, a second asset transfer request can be obtained. And further transferring the asset of the asset holding end to the new asset address of the asset receiving end for storage in response to the second asset transfer request. Optionally, the second asset transfer request carries a new asset address of the asset receiving end.

The selectable block chain platform may also send a second asset transfer response to the asset receiving end after transferring the asset of the asset holder to the new asset address of the asset receiving end for informing that the asset of the asset holder has been successfully transferred to the new asset address of the asset receiving end.

By implementing the embodiment of the invention, the problems that the operation of the resources on the block chain cannot be carried out after the user private key of the receiving end is lost, the long-term sealing of the resources on the block chain and the like exist in the existing scheme can be solved.
