Example 1

Fig. 1 is a flowchart of a method for detecting repetition of a virtual article according to an embodiment of the present invention, where the embodiment is applicable to a situation where repetition detection is performed before a virtual article is issued in a blockchain. In the invention, the issuer of the virtual article realizes the issuance of the virtual article by constructing the blockchain and writing the issuance information of the virtual article into the blockchain, and different blockchains can be established by different issuers of the virtual article. The blockchains constructed by the issuers of the virtual articles can form a blockchain set, and at least one contract of a certification intelligent contract, a virtual article contract, an agent contract and a bridging contract is deployed on each blockchain in the blockchain set so as to realize the virtual article detection method provided by the invention. The certificate storing intelligent contract is used for recording the issued virtual articles in the blockchain collection, specifically, the issuing information of the issued virtual articles can be recorded, the identification information of the issued virtual articles can be recorded, and the hash value of the identification information of the issued virtual articles can be recorded. Virtual item contracts are used to issue virtual items. The proxy contract is used to invoke the deposit intelligent contract. The bridging contracts are used to record requests sent between blockchains. Wherein the virtual item to which the release information has been written on the blockchain is a released virtual item. Repeated detection, it is understood that the issuer of the virtual item detects whether there is the same virtual item on each blockchain as the new virtual item in the blockchain collection before issuing the new virtual item.

The method may be performed by a repetition detection means of a virtual article, which may be implemented in hardware and/or software, which may be configured in an electronic device. As shown in fig. 1, the method includes:

s110, generating and sending a repeated detection request of the virtual article to be issued, wherein the repeated detection request is used for detecting whether the issuing information of the virtual article to be issued exists in at least one alternative block chain.

Virtual items refer to items in the virtual world, and by way of example, virtual items may be digital collections, as well as other virtual items. The virtual article to be issued refers to a new virtual article to be issued, and can be understood as a virtual article which needs to be written into the blockchain. The duplicate detection request refers to a request for duplicate detection of a virtual article to be issued. The duplicate detection request may be generated according to release information of the virtual article to be released. Release information refers to information describing virtual articles, by which different virtual articles can be distinguished, and may include, for example, at least one of a virtual article name, release time, issuer, NFT, and the like. The blockchain to which the issue information of the virtual article to be issued needs to be written is the current blockchain, and it can also be understood that the blockchain constructed by the issuer of the virtual article to be issued is the current blockchain. Among the set of blockchains, blockchains other than the current blockchain are candidate blockchains. The number of candidate block chains is at least one. Illustratively, there are blockchain A, blockchain B and blockchain C in the blockchain collection, the blockchain built by the issuer of the virtual article to be issued is blockchain A, i.e., the virtual article to be issued needs to be written into blockchain A, at which point the current blockchain is blockchain A and the alternate blockchains are blockchain B and blockchain C.

Specifically, the issuer of the virtual article to be issued can generate a repeated detection request according to the issue information of the virtual article to be issued through the network node of the current blockchain, and send the repeated detection request to the alternative blockchain. Wherein, the network node refers to an electronic device capable of connecting with a blockchain. The network node of the current blockchain refers to an electronic device that is capable of connecting to the current blockchain. The network node of the current blockchain may generate a duplicate detection request by a virtual object contract deployed at the current blockchain and send the duplicate detection request to the alternative blockchain. And after the alternative block chain receives the repeated detection request, detecting whether the release information of the virtual article to be released exists or not. The current blockchain and the alternate blockchain may record duplicate detection requests through respective deployed bridging contracts.

Alternatively, the current blockchain may send duplicate detection requests to all of the candidate blockchains in the blockchain set, or may send duplicate detection requests to some of the candidate blockchains in the blockchain set. When the current blockchain sends a repeated detection request to a part of the alternative blockchains in the blockchain set, the alternative blockchains receiving the repeated detection request sent by the current blockchain can forward the repeated detection request to other alternative blockchains so as to realize that all the alternative blockchains receive the repeated detection request.

S120, at least one piece of feedback information corresponding to the repeated detection request is received.

The feedback information refers to information returned to the current blockchain by the alternative blockchain according to the repeated detection request. The feedback information is used to describe the detection result of the candidate block chain. And determining whether the release information of the virtual article to be released exists in the alternative block chain or not through the feedback information. An alternative blockchain returns a feedback information, and thus, the duplicate detection request corresponds to at least one feedback information. The feedback information may be present or absent, where presence refers to the presence of release information of the virtual article to be released on the candidate block chain, and absence refers to the absence of release information of the virtual article to be released on the candidate block chain. The feedback information may also be release information for virtual items that have been released on the chain of candidate blocks.

Specifically, after the release information of the virtual article to be released is detected according to the repeated detection request, each candidate block chain sends feedback information corresponding to the repeated detection request to the current block chain, and the current block chain receives the feedback information of each candidate block chain.

Illustratively, the current blockchain is blockchain A, and the alternate blockchains are blockchain B and blockchain C. The blockchain A generates a repeated detection request 1 for the virtual article a to be sent, and sends the repeated detection request 1 to the blockchain B and the blockchain C. When the block chain B receives the repeated detection request 1, feedback information 1a is returned to the block chain A, and when the block chain C receives the repeated detection request 1, feedback information 2a is returned to the block chain A, and the block chain A receives the feedback information 1a and the feedback information 2a corresponding to the repeated detection request 1. The blockchain A generates a repeated detection request 2 for the virtual object B to be sent, and sends the repeated detection request 2 to the blockchain B and the blockchain C. When the block chain B receives the repeated detection request 2, feedback information 1B is returned to the block chain A, and when the block chain C receives the repeated detection request 2, feedback information 2B is returned to the block chain A, and the block chain A receives the feedback information 1B and the feedback information 2B corresponding to the repeated detection request 2.

S130, determining repeated detection results of the virtual articles to be sent according to the feedback information.

The repeated detection result is a result obtained after the virtual article to be sent is repeatedly detected. For example, the repetition detection result may be repetition or no repetition, where repetition refers to that release information of the virtual article to be released exists in at least one blockchain in the candidate blockchains, and no repetition refers to that release information of the virtual article to be released does not exist in all the candidate blockchains.

Specifically, each piece of feedback information is detected, if the feedback information can be detected to exist, or the release information of the virtual article to be released is detected in the feedback information, the repeated detection result of the virtual article to be released is determined to be repeated; if the feedback information cannot be detected to exist, or the release information of the virtual article to be released cannot be detected in the feedback information, determining that the repeated detection result of the virtual article to be released is no repetition. In the present invention, the method of detecting the feedback information is not limited. For example, if the feedback information 1 is present and the feedback information 2 is absent, detecting each feedback information, and detecting that the feedback information is present, that is, if the feedback information 1 is present, determining that the repeated detection result of the virtual article to be issued is repeated; the feedback information 1 is absent, the feedback information 2 is absent, each feedback information is detected, the existence of the feedback information cannot be detected, and the repeated detection result of the virtual article to be issued is determined to be non-repeated; the feedback information 1 is present, the feedback information 2 is present, each feedback information is detected, the presence of the feedback information can be detected, that is, the presence of the feedback information 1 and the presence of the feedback information 2 are detected, and the repeated detection result of the virtual article to be issued is determined to be repeated.

And S140, determining whether to add the release information of the virtual article to be released into the current blockchain according to the repeated detection result so as to realize release of the virtual article to be released.

Specifically, according to the repeated detection result, when the repeated detection result is repeated, the fact that virtual articles to be issued exist in the alternative block chain is indicated, if the virtual articles to be issued are added into the current block chain, the situation that the virtual articles to be issued are repeatedly issued occurs, so that the issuing information of the virtual articles to be issued cannot be added into the current block chain, and the virtual articles to be issued fail to be issued; and when the repetition detection result is that no repetition exists, indicating that the virtual article to be issued does not exist in the alternative block chain, determining to add the issuing information of the virtual article to be issued into the current block chain, and issuing the virtual article to be issued. For example, the virtual article to be issued may be issued by adding the issue information of the virtual article to be issued to the current blockchain through the virtual article contract.

Example two

Fig. 2 is a flowchart of a method for detecting repetition of a virtual article according to a second embodiment of the present invention, where on the basis of the foregoing embodiment, a request for detecting repetition of a virtual article to be issued is generated and sent, specifically: inquiring whether the virtual article to be issued exists in the certificate-storing intelligent contract corresponding to the current blockchain, and determining a first inquiry result; and generating and sending the repeated detection request under the condition that the first query result is no repetition. As shown in fig. 2, the method includes:

s210, inquiring whether the to-be-issued virtual article exists in the certificate-storing intelligent contract corresponding to the current blockchain, and determining a first inquiring result.

The certificate storage intelligent contracts corresponding to the current blockchain refer to the certificate storage intelligent contracts deployed on the current blockchain, and release information of released virtual articles is recorded in the certificate storage intelligent contracts so as to realize the recording of the released virtual articles in the blockchain set. The first query result is used for describing whether the release information of the virtual article to be released exists in the current blockchain. The first query result may be repeated or non-repeated, where the first query result is repeated, which indicates that the virtual object to be issued exists in the current blockchain certificate storage intelligent contract, and the first query result is non-repeated, which indicates that the virtual object to be issued does not exist in the current blockchain certificate storage intelligent contract.

Specifically, the network node of the current blockchain inquires whether the issuing information of the virtual article to be issued exists in the certificate-storing intelligent contract corresponding to the current blockchain, if the issuing information of the virtual article to be issued exists in the certificate-storing intelligent contract corresponding to the current blockchain, the first inquiring result is determined to be repeated, and if the issuing information of the virtual article to be issued does not exist in the certificate-storing intelligent contract corresponding to the current blockchain, the first inquiring result is determined to be non-repeated. Illustratively, the network node of the current blockchain may invoke the certificate-preserving intelligent contract corresponding to the current blockchain through the proxy contract, so as to query whether the issuing information of the virtual article to be issued exists in the certificate-preserving intelligent contract corresponding to the current blockchain.

And S220, generating and sending the repeated detection request under the condition that the first query result is no repetition.

Specifically, when the first query result is that there is no repetition, generating a repeated detection request according to the release information of the virtual article to be released through the network node of the current block chain, and sending the repeated detection request to the alternative block chain. When the first query result is that repetition exists, generation of repeated detection requests is forbidden, and meanwhile, the first query result can be fed back to an initiator of the virtual article to be sent.

S230, at least one piece of feedback information corresponding to the repeated detection request is received.

The identification information is used to describe the virtual article, by which one virtual article can be uniquely determined. The identification information may be one or more items of content in the release information, which may include, for example, NFT. The hash value refers to a calculation result obtained after hash calculation is performed on the identification information. In the invention, the hash calculation method is not limited, but in the blockchain set, the hash calculation method adopted by the network node of each blockchain is the same. In the authenticated smart contract, a hash value of identification information of the issued virtual item may be stored.

Specifically, the network node of the current blockchain performs hash calculation on the identification information of the virtual article to be issued to obtain a hash value of the identification information, queries the hash value in the intelligent certificate contract corresponding to the current blockchain, determines whether the hash value of the identification information exists in the intelligent certificate contract corresponding to the current blockchain, determines that the first query result is repeated if the hash value of the identification information exists in the intelligent certificate contract corresponding to the current blockchain, and determines that the first query result is non-repeated if the hash value of the identification information does not exist in the intelligent certificate contract corresponding to the current blockchain.

Optionally, the receiving at least one feedback information corresponding to the repeated detection request includes: and according to the repeated detection request, acquiring feedback information fed back by the network node of each alternative block chain from a message queue.

Message queues refer to containers that hold messages during their transmission. In the message queue, the repeated detection request sent by the network node of the current blockchain and feedback information fed back by the network node of the alternative blockchain can be saved.

In the invention, the network node of the current blockchain can send the repeated detection request to the message queue, the network node of each alternative blockchain obtains the repeated detection request from the message queue, detects the release information of the virtual article to be released according to the repeated detection request, and sends the feedback information to the message queue after the detection is completed. The network node of the current block chain acquires feedback information fed back by the network node of each alternative block chain from the message queue.

The repeated detection requests are obtained by the alternative block chains through the request queue, so that the repeated detection requests can be processed in parallel by the alternative block chains, and meanwhile, feedback information is sent to the message queue, so that the processing efficiency of the repeated detection requests can be improved, and the repeated detection efficiency is improved.

Optionally, the repeated detection request includes: the repeated detection request is also used for updating the alternative intelligent contracts corresponding to the alternative blockchains according to the identification information of the virtual articles to be sent.

An alternate smart contract refers to a forensic smart contract deployed in an alternate block chain. The network node of each candidate block chain can inquire candidate intelligent contracts corresponding to the candidate block chain according to the identification information of the virtual article to be sent in the repeated detection request after the repeated detection request is acquired, and whether the identification information of the virtual article to be sent exists in the candidate intelligent contracts or not is determined, if so, the fact that the release information of the virtual article to be sent exists in the candidate block chain is indicated, and if not, the fact that the release information of the virtual article to be sent does not exist in the candidate block chain is indicated. After determining whether the identification information of the virtual article to be sent exists in the alternative intelligent contracts, updating the alternative intelligent contracts corresponding to the alternative block chains according to the identification information of the virtual article to be sent, that is, adding the sending information of the virtual article to be sent in the alternative intelligent contracts.
