Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the specification, as detailed in the appended claims.
The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
In some service scenarios, when a user needs to use a target resource in a second service system in a first service system, resource transfer is required to be performed, and the target resource is transferred from the second service system to the first service system.
The second service system and the first service system are mutually regarded as being not credible; therefore, in order to solve the problem of resource transfer between untrusted service systems, a corresponding service block chain can be constructed by adopting a block chain technology, and a service data chain occurring in a service is stored.
However, for such services of resource transfer, there may be some limitations, for example, the resource to be transferred relates to user privacy, and then such resource is not suitable for direct uplink storage to avoid user privacy disclosure. Therefore, how to implement resource transfer between untrusted service systems based on the block chain is a problem to be solved.
For example, after the user receives the coupon for a certain commodity in the online shopping mall at the coupon platform, the user consumes the coupon in the online shopping mall. Because the preferential platform and the online shopping mall are different platforms, three untrusted domains are formed among the user, the online shopping mall and the preferential platform. The coupons are stored in the coupon platform, and users can have operation authority on the coupons, such as verification, cash withdrawal, recycling and the like.
If this coupon consumption service is implemented using block chain technology, coupon cancellation may not be performed on the chain because the coupon cannot be directly chain-credited. How to guarantee the coupon presented by the user ensures that the coupon consumption of the online shopping mall can be accurately withheld; and how to avoid malicious repeated withholding of non-linked coupons is a problem to be solved.
In the embodiment of the present specification, a resource transfer scheme based on a block chain is provided, and for a case that resources of a user cannot be directly linked to a chain for storage, a second service system (i.e., a service system where the resources are located) may guarantee target resources of the user in advance; indirectly storing the evidence in a mode of storing the digital abstract of the target data and the corresponding relation between the corresponding target data tokens in the block chain; the target data token guarantees the user resource validity certificate for the second business system. Specifically, when a user needs to use a target resource located in a second business system in a first business system, the first business system inquires whether a digital abstract corresponding to the target resource token exists through a block chain by using the target resource token; if the target resource exists, the target resource is shown to exist really, the target resource is further obtained from the second service system, and the target resource of the user is transferred to the first service system by the second service system. Therefore, even if the target resource is not directly linked to the chain for storing the certificate, the certificate can be indirectly stored by utilizing the mode of storing the digital abstract of the target data and the corresponding relation between the target data tokens in the block chain, so that the resource transfer of different service systems (namely between untrusted domains) is realized.
For convenience of distinction, in this specification, a service system storing a target resource worth of a user is referred to as a second service system; the service system targeted by the user when using the target resource is referred to as a first service system.
Explained by the resource of the coupon, the coupon platform can be understood as a second business system; the online shopping mall may be understood as a first business system.
The blockchain described in this specification may specifically include a private chain, a common chain, a federation chain, and the like, and is not particularly limited in this specification.
For example, in one scenario, the block chain may specifically be a federation chain composed of headquarters, branches, agencies, and the like as federation members; the operator of the alliance chain can deploy corresponding business by relying on the alliance chain; the headquarters office, branch office, and agent office, which are members of the federation, described above, may all act as a service node for the service. Each service node can distribute the information related to the service generated or received by itself in the form of transaction in the alliance chain, and after the transaction is processed by the consensus of the consensus nodes in the alliance chain, the information is stored in the distributed database in the alliance chain, so as to complete the uplink certification of the transaction information.
It should be noted that the Transaction (Transaction) described in this specification refers to a piece of data created by a client of a blockchain and needs to be finally issued to a distributed database of the blockchain.
Transactions in a blockchain, generally have a narrow sense of transaction and a broad sense of transaction score. A narrowly defined transaction refers to a transfer of value issued by a user to a blockchain; for example, in a conventional bitcoin blockchain network, the transaction may be a transfer initiated by the user in the blockchain. The broad transaction refers to a piece of business data with business intention, which is issued to the blockchain by a user; for example, an operator may build a federation chain based on actual business requirements, relying on the federation chain to deploy some other types of online businesses (e.g., a certificate-storing business, an anti-counterfeiting verification business, etc.) unrelated to value transfer, and in such federation chain, a transaction may be a business message or a business request issued by a user in the federation chain with a business intention.
The client may include any type of upper layer application that uses the bottom layer service data stored in the blockchain as a data support to implement a specific service function.
In block chain techniques, nodes in a block chain typically need to rely on a corresponding Smart contract (Smart contract) to operate on the block. Operations such as storing, modifying, deleting, etc. in a blockchain all need to rely on smart contracts. The intelligent contract may be a computer protocol intended for application to propagate, verify, or execute contracts in an informational manner that may be deployed on a blockchain. Performing the corresponding operation can be realized by declaring the business logic in the smart contract. Smart contracts allow trusted transactions to be conducted without third parties. These transactions are traceable and irreversible. Smart contracts can provide security over traditional contract methodologies and reduce other transaction costs associated with contracts. In general, the intelligent contracts can be deployed locally at the block link points, and when the nodes need to execute a certain action, the corresponding intelligent contracts can be called, and the intelligent contracts are operated to execute the service logic stated in the intelligent contracts, so that the execution result is obtained.
Referring to the flowchart of the method for indirect uplink of resources shown in fig. 1, the method can be applied in a resource transfer system. The resource transfer system may include at least 2 different business systems, blockchain systems, and clients used by users.
1. The user initiates a certificate storing request aiming at the target resource to the second service system;
the user may specify the target resources that need to be used between the different business systems. Usually, the certificate storing request carries a unique identifier of the target resource, so that the second service system can locate the target resource based on the unique identifier.
2. And the second service system checks the target resource to determine that the target resource really exists and is effective.
The second service system responds to the certificate storing request initiated by the user, and firstly, whether the target resource is positioned in the service system is required to be judged; specifically, whether a resource corresponding to the unique identification exists may be queried locally;
if so, further determining whether the resource is valid. Generally, a resource has a status data, and if the status data of the resource is valid, the resource is valid and can be used.
For example, it is common for a coupon to have a lifespan, which is valid if the coupon is within the lifespan, and invalid if the coupon is outside the lifespan.
And when the second service system judges that the target resource does not exist or exists but is invalid, returning a failure result to the user, and ending the process.
When the second service system determines that the target resource exists and is valid, step 2.2 may be performed.
Preferably, step 2.1 may also be performed before step 2.2.
And 2.1, locking the target resource.
In the target resource locking process, the user cannot perform any operation on the target resource.
And 2.2, submitting the evidence storage transaction aiming at the target resource to the blockchain by the second business system.
For the case where the target resource is located and valid at the second business system, the second business system may submit a deposit transaction for the target resource to the blockchain.
3. And creating a target resource token by the block chain, and storing the corresponding relation between the target resource token and the digital abstract of the target resource in the block chain.
In one implementation, the credentialing transaction may contain a digital digest of the target resource.
In this way, the block chain receives the deposit and certificate transaction of the target resource submitted by the second business system; responding to the evidence storing transaction, calling evidence storing logic issued in the block chain, and creating a target resource token; and storing the corresponding relation between the target resource token and the digital abstract of the target resource in the block chain.
In another implementation, the credentialing transaction may involve the target resource itself;
in this way, the block chain receives the deposit and certificate transaction of the target resource submitted by the second business system; responding to the evidence storing transaction, calling evidence storing logic issued in the block chain, and creating a target resource token; and calculating the digital abstract of the target resource, and storing the corresponding relation between the target resource token and the digital abstract of the target resource in the block chain.
In any way, the digital abstract of the target resource is:
content for the target resource; or, performing hash calculation on the unique information in the target resource content to obtain a hash value.
And 3.1, returning the target resource token to the second service system by the blockchain.
And 3.2, the second service system unlocks the target resource.
And the second service system unlocks the target resource after receiving the target resource token.
4. The second business system provides the target resource token to the user.
And the second business system sends the evidence resource token returned by the block chain to the user, so that the user uses the target resource in other business systems (such as the first business system) through the evidence resource token.
5. And the block chain requests an aging system to monitor the target resource token.
And calling a monitoring logic issued in the block chain by the block chain, and sending a monitoring request for judging whether the target resource token is expired to the aging system.
5.1, the timeliness system carries out timeliness detection on the target resource token.
And the aging system periodically polls the target resource token, and if the target resource token is not used for more than a preset time length, informs the block chain to perform invalidation treatment on the target resource token.
And 5.1.1, the block chain sends a target resource token failure notice to the second service system.
6. The second business system invalidates the target resource.
Through the embodiment, the target resource stored in the second service system by the user has been indirectly stored in the block chain, that is, the corresponding relationship between the digital digest of the target resource and the target resource token is stored. And, the user already has possession of the target resource token. Then, the user can use the target resource in the second service system in other service systems except the second service system, thereby triggering the resource transfer process.
Further, on the basis of the above-mentioned embodiment shown in fig. 1, please refer to the flowchart of the resource transfer method shown in fig. 2 to describe an embodiment of resource transfer based on a block chain.
1. A user initiates a resource transfer request to a first service system; the resource transfer request is a request for transferring the target resource of the user in the second service system to the first service system.
When the user needs to consume the target resource in the second business system in the first business system, the target resource token can be filled in the first business system, so that the first business system can execute the subsequent steps.
2. And the first business system submits the query transaction aiming at the target resource token carried in the resource transfer request to the blockchain.
After receiving a resource transfer request initiated by a user, the first service system may submit a query transaction for a target resource token carried in the resource transfer request to the block chain.
3.1, the block chain inquires whether a digital digest corresponding to the target resource token is stored in the block chain.
And the blockchain responds to the query transaction, invokes query logic declared in an intelligent contract issued in the blockchain, and queries whether the digital abstract corresponding to the target resource token is stored in the blockchain.
And 3.2, returning the inquired digital abstract to the first service system by the block chain.
If the block chain stores the digital digest corresponding to the target resource token, returning the digital digest to the first service system;
4. and the first service system sends the digital abstract to the second service system.
And after receiving the digital abstract corresponding to the target resource token returned by the block chain, the first service system sends the digital abstract to the second service system.
And 5.1, anchoring the target resource corresponding to the digital abstract by the second service system.
And 5.2, the second service system returns the resource information of the anchored target resource to the first service system.
6.1, the first service system determines whether the target resource is available based on the resource information.
Generally, the service system has some use restrictions, and the target resource can be used if the target resource meets the restriction conditions set by the service system. Taking the aforementioned coupon as an example, the returned resource information of the target resource may include the usage conditions of the coupon, such as the usage time, the usage range (such as the specified goods), and the like;
if the using conditions are all met, the first business system can allow the coupon to be used; otherwise, the first business system cannot allow the user to use the coupon.
And 6.2, if the target resource is available, acquiring the target resource from the second service system.
The first service system may request the second service system to perform a target resource transfer operation, thereby obtaining a target resource transferred by the second service system.
7.1, failure transaction of the target resource token submitted by the second business system to the blockchain.
The first business system may send the target resource token to the second business system, so that the second business system submits the failure transaction carrying the target resource token to the blockchain.
And 7.2, the block chain carries out invalidation treatment on the target resource token.
The block chain receives failure transactions which are submitted by the second business system and aim at the target resource token; and responding to the invalidation transaction, calling invalidation logic issued in a block chain, and changing the target resource token from a valid state to an invalid state.
Thus, the entire resource transfer process is completed.
An embodiment of a method mainly based on a first service system according to the present application is described below with reference to fig. 3, where the embodiment may correspond to fig. 2, where a block chain stores a correspondence between a resource token and a digital digest of a resource, and the method includes:
step 310: a first service system receives a resource transfer request initiated by a user; the resource transfer request is a request for transferring target resources of the user located in a second service system to the first service system;
step 320: submitting query transaction aiming at the target resource token carried in the resource transfer request to the block chain;
step 330: receiving a digital digest corresponding to the target resource token returned by the block chain;
step 340: and sending the digital abstract to the second service system, and receiving the target resource corresponding to the digital abstract transferred by the second service system.
In one embodiment, the digital summary of the target resource is:
content for the target resource; or, performing hash calculation on the unique information in the target resource content to obtain a hash value.
In an embodiment, the target resource corresponding to the digital summary transferred by the second service system specifically includes:
the second service system calculates the digital abstract of the local resource to be confirmed;
if the digital abstract of the resource to be confirmed is the same as the digital abstract of the target resource, determining the resource to be confirmed as the target resource;
and sending the determined target resource to the first service system.
In this embodiment, since the digital abstract has a single direction, the second service system cannot reversely derive the target resource based on the digital abstract; therefore, when the target resource needs to be determined, the local resources to be determined can be traversed, and the digital abstract of each resource to be determined is calculated;
if there is a resource to be validated that is the same as the digital digest of the target resource, then the resource to be validated may be determined to be the target resource.
In an embodiment, the method further comprises:

The embodiment is a resource existence check embodiment that is introduced by taking a first service system as an execution subject, and the specific steps of the embodiment may refer to the second service system shown in fig. 1 for performing the resource existence check embodiment. The two are merely implementation dependent.
An embodiment of a method for a blockchain system according to the present invention is described below with reference to fig. 4, where the embodiment may correspond to fig. 2, where a correspondence between a resource token and a digital digest of a resource is stored in the blockchain, and the method includes:

To sum up, the embodiments of the present specification provide a resource transfer scheme based on a block chain, where for a situation that a resource of a user cannot be directly linked to a chain for storage, a second service system (i.e., a service system where the resource is located) may guarantee a target resource of the user in advance; indirectly storing the evidence in a mode of storing the digital abstract of the target data and the corresponding relation between the corresponding target data tokens in the block chain; the target data token guarantees the user resource validity certificate for the second business system. Specifically, when a user needs to use a target resource located in a second business system in a first business system, the first business system inquires whether a digital abstract corresponding to the target resource token exists through a block chain by using the target resource token; if the target resource exists, the target resource is shown to exist really, the target resource is further obtained from the second service system, and the target resource of the user is transferred to the first service system by the second service system.
