Technical Field

The present invention relates to the field of computer technologies, and in particular, to a method and a system for processing a block chain resource.

Background

The block chain technology, also called distributed ledger technology, is an emerging technology for accounting with several computing devices, and maintaining a complete distributed database.

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 method aims to solve the technical problems that once resource transaction is triggered, if a resource end has a resource address error or rejects resources and the like, the resources cannot be withdrawn and recovered, and the resources of a resource removing party are easily damaged and disputed. The invention provides a block chain resource processing method, and a related platform and a system applicable to the method. Fig. 1 is a schematic structural diagram of a system for processing a block chain resource according to an embodiment of the present invention. The system 1000 shown in fig. 1 comprises a blockchain platform 100, a resource holding end 200 and a resource receiving ends 300. Optionally, the blockchain resource processing system 1000 may further include b resource monitoring terminals 400 (not shown) for monitoring the a resource receiving terminals 300, specifically, performing security monitoring on the resources of the a resource receiving terminals 300, similar to a third-party trusted platform. Wherein a and b are positive integers, and the sizes of a and b are not limited.

Blockchain platform 100 has blockchains deployed therein that are used to store data, e.g., support all resources used to store resource holders 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 receiving end 300 is used for receiving or acquiring the corresponding resource of the resource holding end 200. The resource holding end 200 and the resource receiving end 300 according to the present invention may both refer to devices having network communication capability, and 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:

step S201, the resource holding end 200 acquires the respective resource addresses of the resource holding end 200 and the a resource receiving ends 300.

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 holding end 200 or the resource receiving end 300) 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 resource holding end 200 and the a resource receiving ends 300. The address generation request is for requesting allocation of a multiple signature address to the resource holder 200.

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 the respective resource addresses of the resource holding end 200 and the a resource receiving ends 300. 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 resource holding end 200 and the a resource receiving ends 300.

In step S203, the blockchain platform 100 responds to the address generation request, and generates multiple signature addresses by using the resource addresses of the resource holding end 200 and the a resource receiving ends 300. 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 the resource addresses of the resource holding end 200 and the a resource receiving ends 300. Further, the blockchain platform 100 performs address generation on the respective resource addresses of the resource holding end 200 and the a resource receiving ends 300 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 returns the multiple signature addresses to the resource holder 200.

After the blockchain platform 100 allocates the multi-signature address to the resource holding end 200, an address generation response may be fed back to the resource holding end 200, where the address generation response carries the multi-signature address. To return multiple signature addresses to the blockchain platform 100.

Step S205, the resource holding end 200 sends a resource transfer request to the blockchain platform 100, for requesting to transfer all the resources of the resource holding end 200 to the multiple signature addresses for storage. Accordingly, blockchain platform 100 receives the resource transfer request.

After obtaining the multiple signed addresses, resource holder 200 may send a resource transfer request to blockchain platform 100. The resource transfer request carries the identifier of the resource holding end 200, and is used for requesting to transfer all the resources of the resource holding end 200 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. In the present invention, the multiple signature address is an address generated from the respective resource addresses of the resource holding terminal 200 and the a resource receiving terminals 300. There may be one or more resources of the resource holding end 200 under the address, and the resource can be operated by the resource private key generated by the address according to the resource transaction rule. 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 of the resource holding terminal 200 to the multi-signature address for storage.

In response to the resource transfer request, blockchain platform 100 transfers all resources of resource holder 200 to the multi-signature address store. At this time, the resources stored in the multiple signature addresses are accessed by the resource holding end 200 and the a resource receiving ends 300. That is, m first resource terminals exist in the resource holding terminal 200 and the a resource receiving terminals 300, and can access the resources stored in the multiple signature addresses by using their own resource private keys. Wherein m is less 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 holder 200, where the resource transfer response is used to notify that all resources of the resource holder 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 by blockchain platform 100, a corresponding resource transfer response may be sent to resource holder 200, and the response is used to notify resource holder 200 that the resource transfer has been completed currently. At this time, all the resources of the resource holding end 200 belong to the resource holding end 200 and the a resource receiving ends 300, that is, the resource holding end 200 and the a resource receiving ends 300 can access and operate the corresponding resources 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 resources 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 flow chart of another block chain resource processing method according to this embodiment. 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 holder 200 or the resource receiver 300.

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 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. The m first resource terminals belong to the resource terminals of the resource holding terminal 200 and the a resource receiving terminals 300, and specifically, the first resource terminals may be the resource holding terminal 200 or the resource receiving terminals 300. The following describes how the first resource node implements the operations for the corresponding resource of the resource holder 200 in the multiple signature addresses by taking a 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 m first resource-side signature requests. 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 requests of the m first resource ends, and performs the resource operation processing indicated by the resource operation request on the corresponding resource of the resource holding end.

After the signature requests of the m first resource ends are all successfully verified, the block chain platform 100 of the present invention indicates that the block chain platform 100 has the authority to operate all resources of the resource holding ends in the multiple signature addresses. Further, the blockchain platform 100 may respond to the resource operation requests from the m first resource sources to perform corresponding operations on the resources of the resource holder 200 in the blockchain multiple signature addresses. Several specific embodiments of step S305 are specifically set forth below.

In an embodiment, the m first resource terminals include a target receiving terminal, and the resource operation request of the target receiving terminal is a resource reject request of the target receiving terminal. The target receiving end is any one or more receiving ends in a resource receiving ends. The blockchain platform 100 responds to the resource-reject request from the target receiving end, and transfers the corresponding resource from the resource holding end back to the resource address of the resource holding end for storage. Thus, after the target receiving end confirms the resource content, if the resource is found to have a problem, for example, the resource quantity or the resource type, the target receiving end can use its own resource private key to reject the signature, so that the corresponding resource of the resource holding end can be returned to the resource holding end 200.

For example, assume that a blockchain resource processing system 1000 includes a blockchain platform, a resource holding end and 4 resource receiving ends, which are respectively a resource receiving end 1 to a resource receiving end 4. The resource holding end averagely transfers 40 ten thousand digital assets of the resource holding end to 4 resource receiving ends through the resource transfer request, namely, each resource receiving end respectively holds 10 ten thousand digital assets of the resource holding end and stores the digital assets in the multiple signature addresses on the block chain platform. After the optional regional block chain platform stores 10 ten thousand digital assets of the resource holding end, a notification message can be sent to each resource receiving end to notify the resource holding end to transfer the corresponding digital assets of the resource holding end to the resource receiving end, and the corresponding digital assets are stored in the multiple signature addresses.

In the multiple signature technique of 1of 5, a blockchain platform receives any resource end (resource holding end or any resource receiving end) and can send a signature request by using its own resource private key, so as to perform corresponding operations on the resource corresponding to the resource end. For example, in this embodiment, after knowing that the resource holding end only transfers 5 ten thousand digital assets of the resource holding end, the resource receiving end 1 can determine that the asset transfer of the resource holding end is incorrect, and then the resource receiving end 1 can send a signature request to the blockchain platform, where the signature request is obtained by signing a resource denial signature request to be sent by using a resource private key of the resource receiving end 1.

Correspondingly, the block chain platform receives the signature request of the resource receiving terminal 1, and obtains the resource signing rejection request of the resource receiving terminal 1 after the signature verification of the signature request is successful. And further responding the resource rejecting request, and returning the 5 ten thousand digital assets of the resource holding end to the resource holding end without signing.

In another embodiment, the m first resource terminals include a target receiving terminal, and the resource operation request of the target receiving terminal is a resource sign-in request of the target receiving terminal. Accordingly, the blockchain platform 100 responds to the resource signing request, and transfers the corresponding resource of the resource holding end to the resource address of the target receiving end for storage. Therefore, after the target receiving terminal confirms the resource content, if the resource has no problem, the target receiving terminal can use the self resource private key to transfer the corresponding resource to the name of the target receiving terminal, so that the target receiving terminal also retains the self digital signature on the block chain platform, and the conditions of receiving terminal repudiation and the like are prevented.

For example, referring to the above example of resource denial, if the resource receiving end 1 can confirm that the resource holding end transfers assets correctly after knowing that the resource holding end transfers 10 ten thousand digital resources of the resource holding end, the resource receiving end 1 may send a signature request to the blockchain platform, where the signature request is obtained by signing a resource signing request to be sent by using a resource private key of the resource receiving end 1. And after the corresponding regional block chain platform successfully verifies the signature of the signature request, the resource signing request of the resource receiving end 1 can be obtained. And further responding to the resource signing request, transferring the 10 ten thousand digital assets of the resource holding end from the multiple signature addresses to the resource address of the resource receiving end 1 so as to sign the assets transferred by the resource holding end.

In another embodiment, the m first resource terminals include a resource holding terminal 200, and the resource operation request of the resource holding terminal is a resource withdrawal request of the resource holding terminal. Accordingly, the blockchain platform 100 responds to the resource revocation request to revoke the corresponding resource of the resource holder from the multiple signature addresses to the resource address of the resource holder for storage. Therefore, after the resource holding end initiates the resource transfer, if the problems that the resource transfer is wrong (such as resource amount, resource type and the like) and cannot be modified are found, the resource can be withdrawn by using the own resource private key, so that the resource transfer can be initiated again later.

For example, the above-mentioned blockchain resource processing system includes an example of 4 resource receivers. If the resource holding end sends a resource transfer request to the blockchain platform, the resource transfer request is used for requesting that 10 ten thousand digital assets of the resource holding end are transferred to the resource address of the resource receiving end 1. After the resource receiving end sends the resource transfer request, the amount of the digital assets is found to be wrong, the resource holding end originally needs to transfer 20 thousands of money to the resource receiving end, at the moment, the resource holding end can send a signature request to the block chain platform, and the signature request is obtained by utilizing a resource private key of the resource holding end to sign a resource withdrawal request to be sent.

And the corresponding regional block chain platform verifies the signature request after receiving the signature request, and acquires a resource withdrawing request after successfully verifying the signature of the signature request. And then in response to the resource withdrawal request, 5 ten thousand digital assets of the resource holding end are transferred back to the resource address of the resource holding end.

Therefore, the invention is mainly suitable for the following three application scenes: first, the resource receiving end signs for the resource. After the resource receiving end confirms the resource (taking the resource as an electronic bill as an example, the resource can specifically confirm bill information of the electronic bill, such as billing enterprises, bill amount and the like), the resource receiving end signs up by using a self resource private key, and the situations of bill error of a resource holding end (a resource sending end) or receiving end repudiation and the like are prevented. And secondly, rejecting resources by a resource receiving end. After the resource receiving end confirms the resource, if the resource is found to have errors (such as errors in confirming bill information, bill amount and the like of an electronic bill), the resource receiving end can reject to sign back to the resource of the resource holding end (the sending end). Third, the resource holder withdraws the resource. After the resource holding end (sending end) transfers the resource, the resource transfer information is found to have problems, such as error of bill sum and the like, and a scene of re-initiation needs to be withdrawn. The resource holder may revoke the resource to reinitiate the resource transfer before the resource receiver signs in.

It should be noted that, several specific embodiments of the above-mentioned providing S305 of the present invention can be implemented individually or in combination, and the present invention is not limited thereto.

For better understanding of the present invention, the following takes as an example that the resource is a digital asset, and the blockchain resource processing system specifically includes one each of a blockchain platform, an asset holding end and an asset receiving end. Namely, a is 1, and the blockchain platform adopts the multiple signature technology of 1of 2 to realize the safe storage of the assets. Fig. 4 is a flowchart illustrating a method for processing block chain resources according to an embodiment of the present invention. The method shown in fig. 4 specifically includes the following implementation steps:

step S401, the asset holding end sends an address generation request to the blockchain platform, where the request carries the resource addresses of the asset holding end and the asset receiving 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 holding end, and the asset addresses can be acquired actively by the asset holding end or passively received and sent by other equipment, which is not limited in the invention. For example, the asset holder may send an address acquisition request to the asset receiver to correspond to the asset address used to acquire the asset receiver. 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 based on respective resource addresses of the asset holding end and the asset receiving end.

And the block chain 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 holding end. And responding to the address generation request, and performing address generation on the asset addresses of the asset receiving end and the asset holding 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 an asset transfer request to the blockchain platform, for requesting to transfer the asset of the asset holding end to the multiple signature addresses for storage. The respective regional blockchain platform receives the asset transfer request.

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

After receiving the asset transfer request, the blockchain platform can respond to the asset transfer request and transfer the asset of the asset holding end to the multi-signature address for storage. Optionally, the blockchain platform may also return an asset transfer response to the asset holder notifying that the asset of the asset holder has currently been transferred to the multi-signature address store.

Step S405, the asset receiving terminal sends a first signature request to the block chain platform, wherein the first signature request is obtained by signing the asset signing request to be sent by using the asset private key of the asset receiving terminal. The corresponding blockchain platform receives the signature request.

And step S406, after the first signature request is successfully checked, the blockchain platform responds to the asset signing request and returns an asset signing response to the asset receiving terminal, wherein the asset signing response is used for notifying that the asset of the asset holding terminal is transferred to the asset receiving terminal.

After receiving the first signature request, the block chain platform can analyze the first signature request to obtain an asset signing request.
