In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. 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 technical problems that once the resource transaction is triggered, if the resource address is wrong or the resource is rejected, the operations such as withdrawal, recovery and the like cannot be performed on the resource, so that the resource of a resource removing party is damaged easily, and resource disputes are caused easily in the prior art. The invention provides a block chain resource processing method, a related platform and a system suitable for 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, and a resource receivers 300. Optionally, the blockchain resource processing system 1000 may further include b resource monitoring ends 400 (not shown) for monitoring the a resource receivers 300, and specifically, for securely monitoring the a resource receivers 300, similar to the third party trusted platform. Wherein a and b are positive integers, and the sizes of a and b are not limited.
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, for example, an electronic invoice, an electronic ticket, an enterprise ticket, a supply chain finance, and the like.
The resource receiving end 300 is configured to receive or acquire a 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 refer to devices with network communication capability, which may include, but are not limited to, internet devices such as clients, servers, smart phones (e.g. Android mobile phones, IOS mobile phones, etc.), personal computers, tablet computers, palmtops, mobile internet devices (mobile internet devices, MID), or wearable smart devices.
Fig. 2 is a flowchart of a blockchain resource processing method according to an embodiment of the present invention. The blockchain resource processing method is applied to the blockchain resource processing system 1000 shown in fig. 1. The invention provides a method for realizing resource transaction operation by combining a block chain technology and a multiple signature technology in order to ensure the safety of resource storage in a block chain and the legal rights and interests of both sides of resource transaction. The method as shown in fig. 2 comprises the following implementation steps:
step S201, the resource holder 200 obtains the resource addresses of the resource holder 200 and the a resource receivers 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. 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 end (specifically, the resource holding end 200 or the resource receiving end 300) can utilize a preset address generation algorithm and combine the resource public key thereof to generate a corresponding resource address. The address generation algorithm is a system custom set algorithm for generating addresses, which may include, but is not limited to, a blockchain address generation algorithm, a short address generation algorithm, and the like.
In step S202, the resource holder 200 sends an address generation request to the blockchain platform 100, where the request carries the resource addresses of the resource holder 200 and the a resource receivers 300. The address generation request is for requesting that the resource holder 200 be assigned a multi-signed address.
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 the resource holder 200 and the a resource receivers 300. The address generation request is used to request the blockchain platform 100 to generate a corresponding multi-signature address using the resource addresses of each of the resource holder 200 and the a resource receivers 300.
In step S203, the blockchain platform 100 responds to the address generation request to generate a multi-signature address by using the respective resource addresses of the resource holder 200 and the a resource receivers 300. The multi-signature address is used by the blockchain platform 100 to store data.
After the blockchain platform 100 receives the address generation request, the address generation request may be parsed to obtain the resource addresses of the resource holder 200 and the a resource receivers 300, respectively. Further, the blockchain platform 100 generates addresses of the resource holding end 200 and the a resource receiving ends 300 according to a preset address generation algorithm, so as to obtain multiple signature addresses. For the address generation algorithm, reference is made to the foregoing, and details are not repeated here.
In step S204, the blockchain platform 100 returns the multiple signature address to the resource holder 200.
After the blockchain platform 100 allocates the multiple signature addresses to the resource holder 200, an address generation response may be fed back to the resource holder 200, where the address generation response carries the multiple signature addresses. To return the multi-signed address to the blockchain platform 100.
In step S205, the resource holder 200 sends a resource transfer request to the blockchain platform 100 for requesting to transfer all the resources of the resource holder 200 to the multi-signature address for storage. Accordingly, the blockchain platform 100 receives the resource transfer request.
After obtaining the multiple signature addresses, the resource holder 200 may send a resource transfer request to the blockchain platform 100. The resource transfer request carries an identifier of the resource holder 200, and is used for requesting to transfer all the resources of the resource holder 200 to the multiple signature address for storage. Optionally, the resource transfer request may further carry multiple signature addresses, or other system customized information, which is not limited by the present invention.
In practice, the multi-signed address is an address generated by a multiparty private key. The multiple signature address in the present invention is an address generated by the resource addresses of each of the resource holder 200 and the a resource receivers 300. There may be one or more resources at the resource holder 200 under the address, and the resources may be operated by the private key of the resource participating in the address generation according to the resource transaction rule. Optionally, the invention adopts m of n multiple signature technology to realize the storage of resources in the blockchain, specifically, the multiple signature addresses are associated with n resource private keys, when the resource operation is required, the operation of corresponding resources in the multiple signature addresses can be realized by verifying and passing through the signature of m resource private keys in n.
In step S206, the blockchain platform 100 transfers all the resources of the resource holder 200 to the multi-signature address storage in response to the resource transfer request.
The blockchain platform 100 transfers all resources of the resource holder 200 to the multi-signed address store in response to the resource transfer request. The resource stored in the multi-signature address is accessed by the resource holder 200 and the a resource receivers 300. That is, m first resource terminals exist in the resource holding terminal 200 and the a resource receiving terminals 300 to access the resources stored in the multiple signature addresses by using their own resource private keys. Wherein m is less than n, n being 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, the resource transfer response being used to notify that all the resources of the resource holder 200 have been transferred to the multi-signed address. Accordingly, resource holder 200 receives the resource transfer response.
Optionally after the blockchain platform 100 completes the resource transfer, a corresponding resource transfer response may be sent to the resource holder 200 informing the resource holder 200 that the resource transfer is currently completed. 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 private keys.
By implementing the embodiment of the invention, the blockchain platform 100 can apply the multi-signature technology to the blockchain, and store all the resources of the resource holding end by using the multi-signature address, thereby being beneficial to improving the security of the resource storage.
Fig. 3 is a flowchart of another blockchain resource processing method according to the embodiment of the present invention. The method as shown in fig. 3 comprises the following implementation steps:
step 301, the first resource terminal signs a resource operation request to be sent by using a resource private key of the first resource terminal, so as to obtain a signature request. The first resource is a resource holder 200 or a resource receiver 300.
After the blockchain platform 100 stores the resource of the resource holding end 200 to the multiple signature address by using the multiple signature technology, if the corresponding resource to be operated stored in the multiple signature address needs to be operated, the corresponding resource in the multiple signature address needs to be started by using the private key signature of the respective resource of the m first resource ends, so as to perform operations such as resource transfer and the like. The m first resource ends belong to resource ends of the resource holding end 200 and the a resource receiving ends 300, and specifically, the first resource ends may be the resource holding end 200 or the resource receiving end 300. The following describes how the first resource end implements operations for the corresponding resource of the resource holder 200 in the multiple signature address, taking a first resource end as an example. Specifically:
The first resource terminal signs the resource operation request to be sent by utilizing the private key of the first resource terminal to obtain a corresponding signature request. The first resource then sends the signature request to the blockchain platform 100. After receiving the signature request of the first resource, the blockchain platform 100 may perform signature decoding and signature verification on the signature request of the first resource by using the resource public key of the first resource, and after verification is successful, correspondingly obtain the resource operation request of the first resource. The specific embodiment of how to verify the signature request based on the resource public key is not limited.
For example, taking a public resource key and a private resource key as a symmetric key pair as an example, the signature request of the first resource end carries the resource operation request of the first resource end and the signature data of the resource operation request. Accordingly, after the blockchain platform 100 receives the signature request of the first resource, the public key of the first resource may be used to encrypt the resource operation request of the first resource to obtain verification data. And then judging whether the verification data is the same as the received signature data, if so, determining that the signature request of the blockchain platform 100 on the first resource terminal is successful in verification. Otherwise, it is determined that the blockchain platform 100 fails to verify the signature request of the first resource.
In step S302, the m first resource ends send the signature requests to the blockchain platform 100. Accordingly, the blockchain platform 100 receives signature requests of m first resource ends. Accordingly, the blockchain platform 100 receives signature requests of m first resource ends.
Step 303, the blockchain platform 100 parses and verifies the signature requests of the m first resource ends.
In step S304, after the signature verification of the signature request of the m first resource ends is successful, the blockchain platform 100 obtains resource operation requests of the m first resource ends.
In the multiple signature technology, in order to realize the operation processing of the corresponding resources to be operated in the multiple signature address, the blockchain platform needs to acquire m private key signatures of the resources so as to complete authority verification and then can operate the corresponding resources in the multiple signature address. In particular, in the present invention, a plurality of first resource ends may send respective signature requests to the blockchain platform, where the number of the first resource ends needs to be more than m. After signing the signature request of m first resource ends in the plurality of first resource ends, the blockchain platform 100 may obtain respective resource operation requests of the m first resource ends, and further respond to the resource operation request of any one of the m first resource ends.
For example, the present invention takes the example that m first resource ends send respective signature requests to the blockchain platform 100, where the signature requests are obtained by signing the resource operation requests by the first resource ends with their own private keys. The blockchain platform 100 receives signature requests of the m first resource ends, and in particular, the blockchain platform 100 may receive the signature requests sent by the m first resource ends respectively according to a time sequence. The blockchain platform 100 further performs signature verification processing on the signature requests of the m first resource ends. After all signature verification of the signature requests of the m first resource ends is successful, the blockchain platform 100 may respond to the resource operation requests of any or all of the m first resource ends correspondingly.
In step S305, the blockchain platform 100 responds to the resource operation requests of the m first resource ends, and performs the resource operation process indicated by the resource operation request on the corresponding resource of the resource holding end.
After all signature verification of the signature requests of the m first resource ends succeeds, the blockchain platform 100 indicates that the blockchain platform 100 has the authority 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 of the m first resource ends, and perform corresponding operations on the resources of the resource holder 200 in the blockchain multiple signature address. Several embodiments of step S305 are specifically described below.
In one embodiment, the m first resource ends include a target receiving end, and the resource operation request of the target receiving end is a resource refusal request of the target receiving end. The target receiving end is any one or more receiving ends of a resource receiving ends. The blockchain platform 100 responds to the resource refusal request of the target receiving end, and converts the corresponding resource of 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 be problematic, for example, the number of the resource or the type of the resource is problematic, the private key of the resource can be used to reject the signature, so that the corresponding resource of the resource holding end is returned to the resource holding end 200.
For example, assume that a blockchain resource processing system 1000 includes a blockchain platform, a resource holder, and 4 resource receivers, respectively, resource receiver 1 through resource receiver 4. The resource holding end transfers 40 ten thousand digital assets to 4 resource receiving ends in average through the resource transfer request, namely each resource receiving end respectively has 10 ten thousand digital assets of the resource holding end and stores the 10 ten thousand digital assets in multiple signature addresses on a blockchain platform. After the 10 ten thousand digital assets of the resource holding end are saved, the selectable area block chain platform can send a notification message to each resource receiving end, and the notification message is used for notifying the resource holding end to transfer the corresponding digital asset of the resource holding end to the resource receiving end, and the corresponding digital asset is stored in the multiple signature address.
In the multiple signature technology of 1 of 5, the blockchain platform receives a signature request sent by any resource end (resource holding end or any resource receiving end) by using its own private key, so as to operate the corresponding resource of the resource end accordingly. For example, in this example, after knowing that the resource holder only transfers 5 ten thousand digital resources of the resource holder, the resource receiver 1 can confirm that the resource holder transfers the asset in error, and then the resource receiver 1 can send a signature request to the blockchain platform, where the signature request is obtained by signing the resource denial request to be sent by using the resource private key of the resource receiver 1.
Correspondingly, the blockchain platform receives the signature request of the resource receiving end 1, and obtains the resource refusing request of the resource receiving end 1 after the signature request is checked successfully. And further responding to the resource refusing request, returning the 5-thousand digital assets of the resource holding end to the resource holding end, and not giving a signature.
In still another embodiment, the m first resource ends include a target receiving end, where the resource operation request of the target receiving end is a resource signing request of the target receiving end. Accordingly, the blockchain platform 100 responds to the resource signing request to transfer the corresponding resource of the resource holding end to the resource address of the target receiving end for storage. Therefore, after the target receiving end confirms the resource content, if the resource has no problem, the target receiving end can transfer the corresponding resource to the own name by using the own resource private key, so that the target receiving end can also reserve the own digital signature on the blockchain platform, and the conditions of repudiation of the receiving end and the like are prevented.
For example, referring to the above example of resource refusal, if the resource receiving end 1 can confirm that the resource holding end transfers the asset after knowing that the resource holding end transfers 10 ten thousand digital assets of the resource holding end, the resource receiving end 1 can send a signature request to the blockchain platform, where the signature request is obtained by signing the resource signing request to be sent by using the resource private key of the resource receiving end 1. Correspondingly, after the signature request is checked successfully, the blockchain platform can obtain a resource signing request of the resource receiving end 1. And further, responding to the resource signing request, transferring the 10 ten thousand digital assets of the resource holding end from the multi-signature address to the resource address of the resource receiving end 1 so as to sign the resource transferred by the resource holding end.
In yet another embodiment, the m first resource ends include a resource holder 200, where the resource operation request of the resource holder is a resource withdrawal request of the resource holder. Accordingly, the blockchain platform 100 responds to the resource withdrawal request to withdraw the corresponding resource of the resource holder from the multiple signature address to store in the resource address of the resource holder. Therefore, after the resource holding end initiates the resource transfer, if the problems of resource transfer errors (such as the amount of the resource, the type of the resource and the like) and incapability of modification and the like are found, the self resource private key can be used for withdrawing the resource, so that the resource transfer can be restarted later.
For example, reference is made to the above-described blockchain resource processing system including examples of 4 resource recipients. If the resource holder sends a resource transfer request to the blockchain platform, the resource transfer request is used for requesting to transfer the 10 ten thousand digital assets of the resource holder to the resource address of the resource receiver 1. After the resource receiving end sends the resource transfer request, the amount error of the digital asset is found, the resource holding end needs to transfer 20 ten thousand of accounts to the resource receiving end 1, at the moment, the resource holding end can send a signature request to the blockchain platform, and the signature request is obtained by signing a resource withdrawal request to be sent by utilizing a resource private key of the resource holding end.
And correspondingly, the block chain platform verifies the signature request after receiving the signature request, and obtains a resource withdrawal request after the signature request is successfully checked. And further, in response to the resource withdrawal request, transferring the 5-thousand digital assets of the resource holder back to the resource address of the resource holder.
Therefore, the invention is mainly applicable to the following three application scenes: first, the resource receiving end signs in the resource. After confirming the resource (taking the resource as an example, the electronic bill can be specifically confirmed by bill information of the electronic bill, such as an issuing enterprise, bill amount and the like), the resource receiving end signs and receives by utilizing a private key of the resource, so that the conditions of bill errors of the resource holding end (resource sending end), repudiation of the receiving end and the like are prevented. Second, the resource receiving end refuses to sign resources. If the resource receiving end finds that the resource has errors (such as the bill information, bill amount and the like of the confirmed electronic bill have errors) after confirming the resource, the resource receiving end can refuse to sign back the resource of the resource holding end (transmitting end). Third, the resource holder withdraws the resource. After the resource holding end (transmitting end) transfers out the resource, the resource transfer information is found to have problems, such as bill amount errors and the like, and the reinitiation scene needs to be withdrawn. The resource holder may withdraw the resource to reinitiate the transfer of the resource before the resource receiver signs in.
It should be noted that, the above embodiments of the present invention for providing S305 may be implemented alone or in combination, and the present invention is not limited thereto.
For a better understanding of the present invention, the following uses resources as digital assets, and the blockchain resource processing system specifically includes a blockchain platform, an asset holding end, and an asset receiving end, as examples.

in step S401, the asset holder sends an address generation request to the blockchain platform, where the request carries respective resource addresses of the asset holder and the asset receiver. Accordingly, the blockchain platform receives the address generation request.
The asset holding end needs to acquire the respective asset addresses of the asset receiving end and the asset holding end, and the asset addresses can be acquired actively by the asset holding end or can be received passively and sent by other devices. For example, the asset holder may send an address acquisition request to the asset receiver to correspond to the asset address for acquiring the asset receiver. The description of the asset address in the foregoing embodiments is specifically referred to, and will not be repeated here.
Further, the asset holder may send an address generation request to the blockchain platform requesting allocation of the multi-signed address for storing the digital asset of the asset holder.
In step S402, the blockchain platform returns an address generation response to the asset holder in response to the address generation request, where the address generation response carries a multiple signature address, where the multiple signature address is generated based on the respective resource addresses of the asset holder and the asset receiver.
The block chain platform receives the address generation request, and analyzes the address generation request to obtain the asset address of the asset receiving end and the asset address of the asset holding end. And responding to the address generation request, and adopting a preset address generation algorithm to generate the addresses of the assets of the asset receiving end and the asset holding end so as to obtain multiple signature addresses. Accordingly, the blockchain platform returns an address generation response to the asset holder, wherein the address generation response carries the multiple signature address, so that the multiple signature address is returned to the asset holder.
Step S403, the asset holder sends an asset transfer request to the blockchain platform for requesting to transfer the asset of the asset holder to the multi-signature address for storage. The blockchain platform receives the asset transfer request accordingly.
Step S404, the blockchain platform returns an asset transfer response to the asset holder for informing that the asset of the asset holder has been transferred to the multi-signature address store.
After receiving the asset transfer request, the blockchain platform may transfer the asset of the asset holder to the multi-signature address for storage in response to the asset transfer request. Optionally, the blockchain platform may also return an asset transfer response to the asset holder that is used to inform that the asset holder's asset has been transferred to the multi-signed address store.
Step 405, the asset receiving end sends a first signature request to the blockchain platform, where the first signature request is obtained by signing an asset signing request to be sent by using an asset private key of the asset receiving end. The blockchain platform receives the signature request accordingly.
In step S406, after the signing success of the first signature request, the blockchain platform responds to the asset signing request, and returns an asset signing response to the asset receiving end, where the asset signing response is used to notify that the asset of the asset holding end has been transferred to the asset receiving end.
After receiving the first signature request, the blockchain platform can analyze the first signature request to obtain an asset signing request. And further responding to the asset signing request, and transferring the asset of the asset holding end to the asset address of the asset receiving end. The optional block chain platform may further send an asset endorsement response to the asset recipient, the asset endorsement response being used to inform that the asset holder's asset has been successfully transferred to the asset recipient.
Step S407, the asset receiving end sends a second signature request to the blockchain platform, wherein the second signature request is obtained by signing an asset refusal request to be sent by utilizing an asset private key of the asset receiving end. The blockchain platform receives the second signature request accordingly.
Step S408, after the second signature request is checked successfully, the blockchain platform responds to the asset denial request and returns an asset denial response to the asset receiving end. For informing the asset holder of transferring the asset back to the asset holder.
After receiving the second signature request, the blockchain platform can analyze the second signature request to obtain an asset anti-signing request. And further responding to the asset refusal request, and returning the asset of the to-be-transferred asset holder to the asset address of the asset holder. The optional block chain platform may return an asset rejection response to the asset receiving end for informing that the asset of the asset holder has been returned to the asset holder.
Step S409, the asset holder sends a third signature request to the blockchain platform. The third signature request is obtained by signing an asset withdrawal request to be sent by using an asset private key of an asset holding end. Accordingly, the blockchain platform receives a third signature request.
Step S410, after the third signature request is successfully checked, the blockchain platform responds to the asset withdrawal request and returns an asset withdrawal response to the asset holder for informing that the asset of the asset holder has been returned to the asset address of the asset holder.
After receiving the third signature request, the blockchain platform can analyze the third signature request to obtain an asset withdrawal request. And returning the asset of the asset holder to the asset address of the asset holder in response to the asset withdrawal request. The optional block chain platform may return an asset withdrawal response to the asset holder for informing that the asset of the asset holder has been withdrawn to its own asset address.
It should be noted that the execution order of the steps S405, S407, and S409 in the present invention is not limited, and for example, the step S407 may be executed, and then the step S409 is executed, and finally the corresponding specific embodiment of the step S405 is executed. And the three embodiments may be implemented alone or in combination with one another without limitation.
