For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The invention provides a block chain resource processing method, and a platform and a system suitable for the method, in order to solve the technical problem that when an existing user private key (namely a resource private key of a resource receiving end) is lost, resources to be operated in a block chain cannot be operated at will. Fig. 1 is a schematic structural diagram of a system for processing a block chain resource according to an embodiment of the present invention. As shown in fig. 1, the system 1000 for processing blockchain resources includes a blockchain platform 100, a resource holding end 200, a resource receiving ends 300, and b resource monitoring ends 400, where a and b are positive integers. Wherein,

blockchain platform 100 has a blockchain deployed therein, which is used to store data, for example, to support all resources to be operated for storing resource holder 200. The resources to which the present invention relates include, but are not limited to, digital assets, intrinsic assets, electronic red packs, and the like. Digital assets are those assets that are owned or controlled by a business or an individual and that exist as electronic data. The invention takes resources as an example of digital assets on a blockchain, and the digital assets can refer to digital assets such as electronic invoices, electronic bills, enterprise tickets, supply chain finance or other customized digital assets and the like.

The resource monitoring terminal 400 refers to a device for monitoring the resource receiving terminal 300 or the resource holding terminal 200, for example, monitoring the respective resources to be operated of the resource receiving terminal 300 or the resource holding terminal 200, for example, having the right to perform asset transfer, asset freezing, and the like. The b resource monitoring terminals 400 of the present invention are supported for monitoring the a resource receiving terminals 300, and are specifically used for monitoring the resources to be operated of the resource holding terminal 200 that the a resource receiving terminals 300 need to receive respectively.

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

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

in step S201, the resource holding end 200 acquires the respective resource addresses of the a resource receiving ends 300 and the b resource monitoring ends 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. The resource public key and the resource private key are usually presented in the form of a key pair, the key pair is usually generated by a preset key pair generation algorithm, and the key pair generation algorithm is a customized algorithm for generating the key pair, which may include, but is not limited to, a random large prime number generation algorithm, a large power modulus algorithm, and the like. The resource public key is used for generating a resource address, and the resource private key is used for decrypting the resource stored in the resource address to enable the resource, so that the subsequent corresponding operation processing and the like can be conveniently carried out on the resource.

Each resource end (specifically, the resource receiving end 300 or the resource monitoring end 400) of the present invention can generate a corresponding resource address by using a preset address generation algorithm and combining with its own resource public key. The address generation algorithm is a system-customized 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.

Step S202, the resource holding end 200 sends an address generation request to the blockchain platform 100, where the request carries the respective resource addresses of the a resource receiving ends 300 and the b resource monitoring ends 400. Accordingly, blockchain platform 100 receives the address generation request.

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

In step S203, the blockchain platform 100 responds to the address generation request, and generates a multiple signature address by using the resource addresses of the a resource receivers 300 and the b resource managers 400. The multiple signature addresses are used for storing data by the blockchain platform 100.

After receiving the address generation request, the blockchain platform 100 may respond to the address generation request and analyze the address generation request to obtain respective resource addresses of the a resource receiving terminals 300 and the b resource monitoring terminals 400. Further, the blockchain platform 100 performs address generation processing on the respective resource addresses of the a resource receiving terminals 300 and the b resource monitoring terminals 400 according to a preset address generation algorithm to obtain multiple signature addresses. For the address generation algorithm, reference may be made to the foregoing description, and details are not repeated here.

Step S204, the blockchain platform 100 sends an address generation response to the resource holding end 200, where the address generation response carries multiple signature addresses.

After the blockchain platform 100 allocates the multi-signature address to the resource holding end 200, an address generation response carrying the multi-signature address can be fed back to the resource holding end 200, so as to return the multi-signature address to the blockchain platform 100.

Step S205, the resource holding end 200 sends a resource transfer request to the blockchain platform 100, where the resource transfer request is used to request that all resources to be operated of the resource holding end 200 are transferred to the multiple signature addresses for storage. Accordingly, blockchain platform 100 receives the resource transfer request.

Resource holder 200 may send a resource transfer request to blockchain platform 100 after applying for the multiple signature addresses. The resource transfer request may carry an identifier of the resource holding terminal 200, and is used to request that all resources to be operated of the resource holding terminal 200 are transferred to the multiple signature addresses for storage. Optionally, the resource transfer request may also carry multiple signature addresses or other system-defined information, and the like, which is not limited in the present invention.

In practical applications, a multi-signed address is an address generated by a multi-party private key. The multiple signature address is an address generated by the respective resource private keys of a resource receiving end 300 and b resource monitoring end 400, one or more resources to be operated of the resource holding end 200 may be below the address, and the resource private key generated by the address participating in the resource transaction rule can operate the resource. Optionally, the present invention adopts m of n multiple signature technology to realize resource storage in the block chain, specifically, the multiple signature address is associated with n resource private keys, and when resource operation is required, signature can be verified by using m resource private keys of n, so as to realize operation of corresponding resources in the multiple signature address, which is described in detail in the following of the present invention.

Step S206, the blockchain platform 100 responds to the resource transfer request, and transfers all the resources to be operated of the resource holding end 200 to the multi-signature address for storage.

In response to the resource transfer request, the blockchain platform 100 transfers all the resources to be operated of the resource holding end 200 to the multiple signature address storage, where the resources stored in the multiple signature address are accessed by the a resource receiving ends and the b resource monitoring ends. That is, m resource terminals exist in the a resource receiving terminals and the b resource monitoring terminals, and can access the resources stored in the multiple signature addresses by using their 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 all positive integers. Thereby being beneficial to ensuring the safety of resource storage.

Step S207, the blockchain platform 100 sends a resource transfer response to the resource holding end 200, where the resource transfer response is used to notify that all resources to be operated of the resource holding end 200 have been transferred to the multiple signature addresses. Accordingly, the resource holder 200 receives the resource transfer response.

Optionally, after completion of the resource transfer, the blockchain platform 100 may send a corresponding resource transfer response to the resource holder 200, where the response is used to notify 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 corresponding resources to be operated of the resource holding end 200 by using their own resource private keys.

By implementing the embodiment of the present invention, the blockchain platform 100 can apply the multiple signature technology to the blockchain, and store all the resources to be operated at the resource holding end by using the multiple signature addresses, which is beneficial to improving the security of resource storage.

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

step S301, 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 signature request. The first resource is the resource receiver 300 or the resource manager 400.

After the block chain platform 100 stores the resources of the resource holding end 200 to the multiple signature addresses by using the multiple signature technology, if the corresponding resources to be operated stored in the multiple signature addresses need to be operated, the corresponding resources to be operated in the multiple signature addresses can be enabled by using the respective resource private keys of the m first resource ends to perform operations such as resource transfer on the resources. The m first resource terminals belong to resource terminals of the a resource terminals 200 and the b resource controllers 300, and specifically, the first resource terminals may be the resource terminals 200 or the resource controllers 300. The following describes how the first resource node implements the operation on the corresponding resource to be operated of the resource holder 200 in the multiple signature addresses by taking the first resource node as an example. Specifically, the method comprises the following steps:

the first resource terminal signs the resource operation request to be sent by using the own resource private key to obtain a corresponding signing request. The first resource in turn sends the signature request to blockchain platform 100. After receiving the signature request of the first resource end, the block chain platform 100 may perform de-signing and signature checking on the signature request of the first resource end by using the resource public key of the first resource end, and after the verification is successful, correspondingly obtain the resource operation request of the first resource end. The specific implementation of how to validate the signature request based on the resource public key is not limited.

For example, taking the resource public key and the resource private 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 receiving the signature request of the first resource end, the blockchain platform 100 may encrypt the resource operation request of the first resource end by using the resource public key of the first resource end to obtain the verification data. And then judging whether the verification data is the same as the received signature data, and if so, determining that the signature request of the blockchain platform 100 on the first resource is successfully verified. Otherwise, it is determined that the blockchain platform 100 fails to verify the signature request of the first resource.

Step S302, the m first resource ends send respective signature requests to the blockchain platform 100. Accordingly, the blockchain platform 100 receives signature requests from m first resource peers including one or more resource manager peers 400. Accordingly, the blockchain platform 100 receives m first resource-side signature requests.

Step S303, the block chain platform 100 analyzes and verifies the signature requests of the m first resource ends.

Step S304, after the signature verification of the signature requests of the m first resource ends is successful, the block chain platform 100 obtains resource operation requests of the m first resource ends.

In the multiple signature technology, in order to implement the operation processing of the corresponding resource to be operated in the multiple signature address, the block chain platform needs to obtain m resource private key signatures to complete the authority verification and then can perform the operation processing on the corresponding resource in the multiple signature address. Specifically, in the present invention, a plurality of first resource sources may send respective signature requests to the block chain platform, and the number of the first resource sources needs to exceed m. After the signature request of m first resource ends of the plurality of first resource ends is successfully checked, the block chain platform 100 may obtain the resource operation request of each 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, in the present invention, the m first resource terminals send respective signature requests to the block chain platform 100, where the signature requests are obtained by the first resource terminals signing the resource operation request by using their own resource private keys. The block chain platform 100 receives the signature requests of the m first resource terminals, and specifically, the block chain platform 100 may receive the signature requests sent by the m first resource terminals respectively according to the time sequence. Further, the blockchain platform 100 performs signature verification processing on the m first resource-side signature requests. After all signature verification of the signature requests of the m first resource terminals is successful, the block chain platform 100 may respond to the resource operation request of any or all first resource terminals in the m first resource terminals.

Step S305, the blockchain platform 100 responds to the resource operation request of the second resource, and performs the resource operation processing requested by the resource operation request on the corresponding resource to be operated of the resource holding end 200. The second resource end is a resource manager end 400 among the m first resource ends.

After the signature requests of the m first resource ends are all successfully verified, the blockchain platform 100 of the present invention indicates that the blockchain platform 100 has the authority to perform operations (e.g., access, transfer) on all resources to be operated stored in the multiple signature addresses. Further optionally, the blockchain platform 100 may respond to a resource operation request of a second resource end, where the second resource end is any one or more resource ends of the m first resource ends, and specifically may be a resource receiving end. In particular, the second resource peer of the present invention is embodied as one or more resource manager peers 400 of the m first resource peers. If the second resource end is the resource manager end 400, the resource manager end 400 sends a signature request carrying the resource operation request to the block chain platform 100, and the operation processing of the corresponding resource to be operated can be completed without the participation of the resource receiver end 300. It is avoided that when the resource private key (i.e. the user private key) of the resource receiving end 300 is lost, the corresponding resource to be operated on the block chain cannot be operated.

Several embodiments of step S305 are described below.

In an embodiment, if the resource operation request is a resource transfer request, the resource transfer request carries a resource address of a target receiving end. The resource address of the target receiving end is configured by the second resource end in a self-defined manner, for example, the resource address of the second resource end itself, or the resource address of any resource receiving end specified by the second resource end, and the like.

The corresponding local block chain platform 100 can respond to the resource transfer request of the second resource end, and transfer the resource to be operated corresponding to the resource holding end 200 in the multiple signature addresses from the multiple signature addresses to the resource address of the target receiving end for storage, so that the resource transfer can be completed without the participation of the target receiving end, and the problems that the resource on the block chain cannot be operated any more due to the loss of the private key of the resource receiving end and the like are avoided under the condition that the resource transfer safety is ensured. Wherein, the target receiving end is a receiving end supervised by a second resource end (resource supervision end) in a resource receiving ends.

For example, assume that a blockchain resource processing system 1000 includes a blockchain platform, a resource holding end, 10 resource receiving ends and 2 resource monitoring ends. Wherein, the resource receiving end 1 to the resource receiving end 5 are respectively supervised by the resource supervisor end 1, and the resource receiving end 6 to the resource receiving end 10 are respectively supervised by the resource supervisor end 2. The resource holder 200 has 100 ten thousand digital assets stored in the multi-signature addresses in the blockchain, which are generated by the respective resource addresses of 10 resource receivers and 2 resource supervisors. If the resource holder 200 needs to transfer 100 ten thousand digital assets to 10 resource receivers on average. This example shows: the resource monitoring end 1 respectively monitors 10 ten thousand digital assets of the resource receiving end 1 to the resource receiving end 5. The resource monitoring end 2 respectively monitors 10 ten thousand digital assets of the resource receiving end 6 to the resource receiving end 10.

In the multiple signature technology adopting 2of 12, if the block chain platform receives the signature requests sent by the 2 resource monitoring terminals respectively and successfully verifies the signatures of the 2 signature requests, the respective resource transfer requests of the 2 resource monitoring terminals can be obtained. The resource transfer request of the resource monitoring terminal 1 carries resource addresses (also referred to as transaction addresses) of the resource receiving terminals 1 to 5, and is used for requesting transfer of 10 ten thousand digital assets of the resource holding terminal for 5 resource receiving terminals respectively. The resource transfer request of the resource monitoring terminal 2 carries the respective resource addresses of the resource receiving terminal 6 to the resource receiving terminal 10, and is used for requesting to transfer 10 ten thousand digital assets of the resource holding terminal for the 5 resource receiving terminals respectively.

The corresponding regional chain platform can respond to the resource transfer request of the resource monitoring end 1, and respectively transfer 10 ten thousand digital assets of the resource holding end stored in the multiple signature addresses to the respective resource addresses of the resource receiving end 1-the resource receiving end 5. Similarly, the blockchain platform can respond to the resource transfer request of the resource monitor end 2, and transfer 10 ten thousand digital assets stored in the multiple signature addresses from the resource holding end to the respective resource addresses of the resource receiving end 6 to the resource receiving end 10.

In another embodiment, the resource operation request is a resource update request, which is used to request to update a resource to be operated corresponding to the resource holding end. And the corresponding regional block chain platform responds to the resource updating request of the second resource end and updates the corresponding resource to be operated of the resource holding end stored in the multiple signature addresses. For example, updating the resource type of the corresponding resource to be operated, the effective time for storing the resource, the resource size, or other customized resource information, etc., which is not limited in the present invention.

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

For example, referring to the above example that the blockchain resource processing system 1000 includes 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 resource monitoring end 1 under its supervision. The following describes how to realize resource borrowing by taking the second resource end as the resource manager end 1 as an example. The resource borrowing request is used for indicating that 10 ten thousand digital assets of the resource receiving terminal 1 are borrowed to the resource borrowing terminal. The resource borrowing request carries a resource address of a resource borrowing end.

After receiving the resource borrowing request of the resource monitoring end 1, the corresponding regional block chain platform can respond to the resource borrowing request, borrow and transfer the 10 ten thousand digital assets of the resource holding end stored in the multiple signature addresses to the resource borrowing end, and does not need to be determined by the resource receiving end 1, so that the operation is convenient. Optionally, after completing borrowing of the corresponding asset to be operated, the resource monitoring end 1 may send a response message to the resource receiving end 1, so as to notify that 10 ten thousand digital assets of the resource receiving end 1 have been successfully borrowed and transferred to the resource borrowing end.

In another embodiment, the resource operation request is a resource deactivation request, and the resource deactivation request is used to indicate to deactivate the corresponding resource to be operated of the resource holding end. Specifically, the blockchain platform may respond to the resource deactivation request from the second resource source, and perform freezing processing on the resource to be operated corresponding to the resource holding end in the multiple signature addresses, so as to close the access right for the resource to be operated and deactivate the resource to be operated.

For example, the above-mentioned blockchain resource processing system 1000 includes a blockchain platform, a resource holding end, 10 resource receiving ends and 2 resource monitoring ends, and the second resource end is a resource monitoring end 1. The resource supervisor end 1 sends a resource deactivation request to the blockchain platform, where the deactivation request is specifically used to request to stop using the corresponding digital assets of the resource holding end supervised by the resource supervisor end 1 itself, and this example may specifically refer to stopping using 10 ten thousand digital assets of each of the supervised resource receiving ends 1 to 5, that is, stopping using 50 ten thousand digital assets of the resource holding end.

After receiving the resource deactivation request of the resource monitoring end 1, the corresponding regional block chain platform can respond to the resource deactivation request, and perform freezing processing on 50 ten thousand digital assets of the resource holding end stored in the multiple signature addresses, specifically 10 ten thousand digital assets to be transferred to each of the resource receiving end 1 to the resource receiving end 5. For frozen digital assets, both the resource receiving end and the resource monitoring end have no right to reuse the frozen digital assets, and need to be started and operated normally after being thawed.

In another embodiment, the resource operation request is a resource enabling request, and the corresponding resource to be operated at the resource holding end is the frozen corresponding resource to be operated. The corresponding regional block chain platform may respond to the resource enabling request from the second resource end, and perform unfreezing processing on the resource to be operated corresponding to the resource holding end after being frozen in the multiple signature addresses, so as to recover the usage right of the corresponding resource to be operated, for example, the corresponding resource to be operated may be enabled, and the corresponding resource to be operated may be subjected to operation processing such as transfer, update, and the like.

For example, referring to the above example of the resource deactivation request, if the corresponding resource to be operated at the resource holding end is frozen, if the corresponding resource to be operated is to be reused, the corresponding resource to be operated needs to be defrosted. In this example, if the resource manager 1 or 5 resource receiving terminals managed by the resource manager 1 want to re-enable the corresponding resources to be operated of the resource holding terminal, the resource manager 1 may send a resource enabling request to the blockchain platform, so as to request to perform unfreezing processing on 10 ten thousand digital assets of each of the 5 resource receiving terminals, so as to enable the 50 ten thousand digital assets.

The corresponding regional block chain platform receives the resource starting request of the resource monitoring end 1, responds to the resource starting request, and unfreezes 50 ten thousand digital assets of the frozen resource holding end in the multiple signature addresses, and specifically can unfreeze 10 thousand digital assets of each of the resource receiving end 1 to the resource receiving end 5. The subsequent resource monitoring end 1 and the resource receiving ends 1 to 5 can conveniently operate the corresponding digital assets by using the respective resource private key signatures of the resource monitoring end 1 and the resource receiving ends, such as asset transfer and the like.

It should be noted that the present invention is applied to a block chain scenario, and particularly, may be applied to a block chain electronic invoice, an electronic bill, supply chain finance, a digital asset, or other scenarios with digital asset supervision requirements, and the present invention is not limited thereto.

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

To help better understand the present invention, taking resources as digital assets as an example, the blockchain resource processing system is also called a blockchain asset processing system, and the system includes 1 each of a blockchain platform, an asset holding end, an asset receiving end and an asset monitoring end, that is, a-b-1 in the above description of the present invention. And the block chain platform realizes the storage of the digital assets by adopting 1of 2 multiple signature technologies. Fig. 4 is a schematic flow chart of another block chain 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:

step S401, the asset holding end sends an address generation request to the blockchain platform, wherein 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 of the invention needs to acquire the 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 passively received and sent by other equipment, and the invention is not limited. For example, the asset holding end may send an address acquisition request to the asset receiving end and the asset supervising end, respectively, to correspond to the asset address used to acquire the asset receiving end and the asset supervising end. For the asset address, reference may be made to the related description in the foregoing embodiments, and details are not repeated here.

Further, the asset holder may send an address generation request to the blockchain platform requesting assignment of multiple signature addresses for storing the digital assets of the asset holder.

Step S402, the block chain platform responds to the address generation request and returns an address generation response to the asset holding end, wherein the address generation response carries multiple signature addresses, and the multiple signature addresses are generated by using the asset addresses of the asset receiving end and the asset monitoring end respectively.

And the blockchain platform receives the address generation request, analyzes the address generation request and obtains 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 performing address generation on the asset addresses of the asset receiving end and the asset monitoring end by adopting a preset address generation algorithm to obtain multiple signature addresses. And the corresponding regional block chain platform returns an address generation response to the asset holding end, wherein the address generation response carries the multiple signature addresses so as to return the multiple signature addresses to the asset holding end.

Step S403, the asset holding end sends a first asset transfer request to the blockchain platform, where the first asset transfer request is used to request that the asset holding end transfer the asset to the multi-signature address for storage. The respective regional blockchain platform receives the asset transfer request.

Step S404, the block chain platform returns a first asset transfer response to the asset holding end, wherein the first asset transfer response is used for notifying that the asset holding end has transferred the asset to the multi-signature address storage.

After receiving the first asset transfer request, the blockchain platform may transfer the asset at the asset holding end to the multi-signature address storage in response to the first asset transfer request. Optionally, the blockchain platform may also return an asset transfer response to the asset holder for notifying the asset holder that the asset has transferred itself to the multi-signature address for storage. At this time, the asset receiving end and the asset monitoring end can operate the assets stored in the multiple signature addresses by using the own resource private key.

And S405, the asset manager sends a signature request to the block chain platform, wherein the signature request is obtained by using the asset private key of the asset manager to sign the second asset transfer request. The corresponding blockchain platform receives the signature request.

And step S406, after the signature request is successfully checked, the blockchain platform responds to the 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 notifying that the asset of the asset holding end is transferred to the appointed asset address. The designated asset address is an address which is custom designated by the resource monitoring end and used for receiving the asset, such as a transaction address of an asset receiving end.

After receiving the signature request, the blockchain platform carries the second asset transfer request and the signature data aiming at the request. Further, the signature request may be parsed and verified, and after the verification is successful, the second asset transfer request may be obtained, and the verification of the signature request may be specifically referred to in the related description of the foregoing embodiments. In practical application, the second asset transfer request carries a designated asset address, and the following description of the present invention takes the transaction address of the asset receiving end as an example to illustrate related contents.

And the block chain platform can respond to the second asset transfer request and transfer the asset at the asset holding end to the transaction address at the asset receiving end from the multiple signature addresses, and the asset transaction can be completed without being confirmed by the asset receiving end, so that the efficiency of asset processing is improved. By implementing the embodiment of the invention, the asset processing efficiency is favorably improved, and the technical problems that the user private key of the conventional asset receiving end is lost and the assets on the block chain can not be operated and the like are solved.
