In order to ensure the safety of the transaction in the blockchain network, after receiving a transaction application initiated by the transaction initiator to the blockchain network, the validity authentication is carried out on the identity authentication statement of at least one of the transaction initiator and the transaction receiver which is certified on the blockchain network.
Specifically, the validity authentication of the authentication assertion for at least one of the transaction initiator and the transaction recipient includes at least: verifying whether at least one of the transaction initiator and the transaction receiver stores the identity authentication declaration or the related identification information of the identity authentication declaration on the blockchain network, verifying the validity of the identity authentication declaration stored on the blockchain network by the transaction initiator and the transaction receiver, verifying whether the identity authentication declaration stored on the blockchain network by the transaction initiator and the transaction receiver or the related identification information of the identity authentication declaration is within the valid time, verifying whether the identity authentication declaration stored on the blockchain network by the transaction initiator and the transaction receiver has the right to perform asset transaction, and the like.
Further, in an embodiment, in step S120, validity verification is performed on the authentication assertions that are stored on the blockchain network by the transaction initiator and the transaction receiver. The verification sequence of the transaction initiator and the transaction receiver is not particularly limited, and the validity of the identity authentication assertion stored on the blockchain network by the transaction initiator can be verified before the validity of the identity authentication assertion stored on the blockchain network by the transaction receiver is verified. In other embodiments, the validity of the authentication assertion may be verified for both the transaction initiator and the transaction recipient.
In another embodiment, after performing other types of verification or higher level authentication on one of the transaction initiator or the transaction receiver, or according to the preset configuration of the blockchain transaction verification system, the validity verification may be performed only on the authentication assertion of the transaction initiator or only on the transaction receiver in step S120, which may be set or adjusted according to the requirements of different embodiments.
S130: and if the identity authentication statement is authenticated to be valid, executing the subsequent operation of the transaction application.

In the embodiment corresponding to fig. 1, validity authentication is performed on the identity authentication declaration certified by at least one of the transaction initiator and the transaction receiver in the transaction application on the blockchain network, and when the identity authentication declaration is authenticated to be valid, subsequent operations of the transaction application can be executed, otherwise, the transaction application is rejected, so that the security of asset transaction in the blockchain network can be better ensured.
Referring to fig. 2, fig. 2 is a flowchart illustrating another embodiment of a method for verifying a blockchain transaction according to the present invention. In the current embodiment, the method provided by the present application includes:
s210: and receiving a transaction application initiated by the transaction initiator to the blockchain network. Step S210 is the same as step S110 corresponding to fig. 1, and may specifically refer to the description of the corresponding part in fig. 1 above, and is not described in detail here.
Step S120 of validating the authentication assertion certified by at least one of the transaction initiator and the transaction recipient on the blockchain network in the embodiment illustrated in fig. 1 includes step S220 and step S230.
S220: and acquiring the identity information pre-registered in the blockchain network by at least one of the transaction initiator and the transaction receiver.
As described above, the transaction application includes the identification information of the transaction initiator and the transaction receiver on the blockchain network, and the identification information is obtained by registering in the blockchain network in advance. After receiving the transaction request in step S210, the identification information pre-registered in the blockchain network by at least one of the transaction initiator and the transaction receiver is obtained from the received transaction request.
Specifically, in the current embodiment, validity authentication is performed on the identity authentication declaration that the transaction initiator and the transaction receiver are certified on the blockchain network, then in step S220, the identity identification information that the transaction initiator and the transaction receiver are registered in advance on the blockchain network is obtained. In another embodiment, the validity of the authentication assertion is verified only for one of the transaction initiator and the transaction receiver, and the identification information of only one of the transaction initiator and the transaction receiver can be obtained.
S230: and inquiring the identity authentication statement related to the identity identification information on the block chain network, and carrying out validity authentication on the inquired identity authentication statement.
After the identity identification information of at least one of the transaction initiator and the transaction receiver is obtained, whether an identity authentication statement related to the identity identification information is stored in the blockchain network or not is inquired on the blockchain network. Further, the authentication assertion may be stored on the blockchain network in the form of a HASH value.
If the identity authentication statement related to the identity identification information is not inquired after inquiry, the identity authentication statement corresponding to the identity identification information which is not stored in the block chain network can be directly judged and obtained, and further the transaction application can be refused.
If the identity authentication statement associated with the identity identification information is obtained through query, validity authentication is further carried out on the identity authentication statement obtained through query.
The form of the identity authentication assertion stored in the blockchain network at least comprises related identification information of the identity authentication assertion, a preset key corresponding to the identity authentication assertion and partial information of the identity authentication assertion. Wherein, the related identification information of the identity authentication assertion can comprise a HASH value of the identity authentication assertion; the partial information of the authentication assertion refers to information that is hidden or selected to be partially insensitive and unique in the blockchain network. In the current embodiment, sensitive information of a blockchain network transaction account can be better protected on the premise of improving the security of blockchain transactions by storing relevant identification information of an identity authentication statement, a preset key corresponding to an identity authentication statement or partial information of the identity authentication statement.
The identity authentication statement is generated by a third party authentication mechanism after at least one of the transaction initiator and the transaction receiver is authenticated, is associated with the identity identification information and then is stored on the block chain network. Specifically, the third-party certification authority may associate the HASH value of the authentication assertion with the identity information and store the association in the blockchain network according to the setting; the third-party certification authority may also store the key of the identity authentication declaration in the blockchain network after associating the key with the identity identification information, or the third-party certification authority may also store the identity authentication declaration in the third-party certification authority itself, and then store the third-party certification authority in the blockchain network after hiding the preset sensitive information in the identity authentication declaration and associating the third-party certification authority with the identity identification information so as to call the third-party certification authority when verifying the validity of the identity authentication declaration.
The process of identity authentication claim validity authentication may include: according to the technical scheme provided by the application, the identity authentication declaration of each blockchain network transaction account has a corresponding time limit, for example, the time limit duration can be set to be one year, different valid periods can be set according to different grades of blockchain network transaction accounts, for example, the valid period of the identity authentication declaration of a blockchain network transaction account with a higher grade can be set to be longer, and the valid period of the identity authentication declaration of a blockchain network transaction account with a lower grade can be set to be shorter.
And when the identity authentication declaration is not in the valid period, judging that the current identity authentication declaration is invalid. Otherwise, when the identity authentication declaration is within the valid period, the current identity authentication declaration is judged to be valid.
Further, in another embodiment, it is also confirmed whether the current transaction initiator has the right to conduct asset transactions and whether there is a transaction limit based on the authentication assertion. When the identity authentication declaration of the transaction initiator shows that the identity authentication declaration does not have the authority of performing asset transaction, the current identity authentication declaration is judged to be invalid for the current transaction application, otherwise, the current identity authentication declaration can be judged to be valid. Similarly, if the transaction amount initiated by the current transaction initiator is larger than the amount right in the identity authentication statement based on the identity authentication statement, the current identity authentication statement is judged to be invalid for the current transaction application. Otherwise, the current identity authentication assertion can be judged to be valid.
Still further, in other embodiments, it may be determined for the authentication assertion that the authentication assertion is still valid for the term, has the authority to transact the asset, has a transaction limit, and so on. It is understood that other contents of the authentication assertion may be verified according to the preset setting in other embodiments.
S240: and if the identity authentication statement is authenticated to be valid, executing the subsequent operation of the transaction application.
In the current embodiment, if the authentication assertion is authenticated as valid, step S250 is performed. Step S240 is the same as step S130 corresponding to fig. 1, and may specifically refer to the description of the relevant parts above, and is not described in detail here.
S250: and directly transferring the assets corresponding to the transaction application to a transaction receiver.
In the current embodiment, when the identity authentication statement for storing the certificate on the blockchain network in the transaction initiator and the transaction receiver is judged to be valid, the blockchain network executes the transaction application of the transaction initiator and directly transfers the assets corresponding to the transaction application to the transaction receiver, thereby completing the transaction application of the transaction initiator.
In another embodiment, if the authentication assertion is authenticated as valid, the asset transfer corresponding to the transaction application is not directly executed, and before determining whether to perform the asset transfer, the following steps are also executed: and submitting the transaction application to a third-party auditing mechanism, and transferring the assets corresponding to the transaction application to a transaction receiver after the third-party auditing mechanism passes the auditing. The transaction application is submitted to the third-party auditing mechanism, wherein the auditing of the identity authentication statement can be carried out again, and the auditing of other dimensions different from the identity authentication statement can also be carried out, so that the security of asset transaction in the block chain network is ensured.
Specifically, submitting the transaction application to a third-party auditing agency for auditing of other dimensions may include: and verifying the legality of the transaction content, verifying the risk of the personal information of the block chain network transaction account holder of the transaction initiator and the like. The legality examination of the transaction content is to determine whether the suspicion of money laundering exists, and the risk examination of the personal information of the block chain network transaction account holder of the transaction initiator is to determine whether the block chain network transaction account holder has records of illegal behaviors such as money laundering, fraud and the like, so that the security of the block chain network transaction is ensured.
After the third-party audit organization passes the audit, the third-party audit organization feeds back the audit result to the block chain network, and if the third-party audit organization passes the transaction application, the block chain network executes the assets corresponding to the transaction application and directly transfers the assets to the transaction receiver; otherwise, if the third party auditing mechanism rejects the transaction application after auditing, the block chain network rejects the transaction application.
S260: and if the identity authentication statement does not exist or is authenticated to be invalid, refusing the transaction application.
Step S260 is the same as step S140 corresponding to fig. 1, and may specifically refer to the description of the relevant parts above, and is not described in detail here.
Further, the method for verifying the blockchain transaction provided by the present application further includes: and deleting or setting the identity authentication statement into an invalid state according to the revoking instruction. The revoking instruction may be an instruction sent when the block chain network determines that a certain identity authentication declaration is invalid, or may be an instruction sent to the block chain network when a third-party authentication authority or a third-party auditing authority determines that a certain identity authentication declaration is invalid. Still further, the revoking instruction may be an instruction for revoking the identity authentication assertion of the transaction initiator when the number of times that the transaction initiator is determined to be invalid or the number of times that the transaction application is denied exceeds a set number of times within a set time, or an instruction for locking a network account of a block chain issued by a certain monitoring part is received. When the identity authentication statement of a certain blockchain network transaction account is set to be in an invalid state or a locked state, the assets under the account are locked and cannot be transacted until the third-party certification authority recovers the identity authentication statement corresponding to the blockchain network transaction account, and the assets allow the account holder to continue transacting. The scheme can intercept and prevent illegal transactions, and make identity authentication independent of asset transaction and asset locking, namely, a third-party authentication mechanism can only lock assets, but cannot transfer user assets beyond an account holder, so that the right of the account holder is well protected.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for verifying a blockchain transaction according to an embodiment of the present invention. In the current embodiment, the execution subject of the method for blockchain transaction verification provided by the present application is an authentication device of a third party authentication authority that can communicate with a blockchain network. In the current embodiment, the method provided by the present application includes:
s310: and acquiring the identity identification information pre-registered in the blockchain network by the user.
In the technical scheme provided by the application, if a user wants to perform asset transaction on the blockchain network, the user needs to register in advance on the blockchain network to obtain identity information according to personal identity information or a proxy agency, and the identity information has uniqueness in the blockchain network.
Further, the identification information may include a VeDID identification code. Furthermore, the id information may also be set with different values through setting bits instead of different setting meanings, for example, some bits may be set for the id information to indicate different levels of the blockchain network transaction account, set years, and the like, and the setting and the adjustment may be specifically performed according to actual needs.
In the process of identity authentication, identity identification information which is input by a user through a terminal and is registered in a block chain network in advance is acquired.
S320: and acquiring the authentication information submitted by the user.
The user needs to submit authentication information to the third-party certification authority, where the authentication information at least includes information required by the third-party certification authority to acquire an authentication declaration, such as at least one of a user application form, personal identification document information, a personal academic degree certification, a personal declaration, a qualification certificate of an agency, and the like, which is specifically set by the third-party certification authority, and detailed descriptions thereof are omitted here.

S410: and signing the identity authentication assertion once by using the first key, and feeding back the identity authentication assertion after the signing once to the user. The first key is a key held by the third-party certification authority, and is used for signing the identity authentication declaration by using the first key after the identity authentication information submitted by the user passes in the process of applying the identity authentication declaration by the user, so that the third-party certification authority can prove that the identity authentication declaration passes self-verification to the block chain network or other ends, namely the signature can be understood as the approval of the identity authentication declaration.
And the third-party certification authority feeds back the identity certification statement subjected to the one-time signature to the user. The third-party certification authority is a certification authority different from the blockchain network, the user and the agency, and the certification equipment of the third-party certification authority can communicate with the blockchain network and the terminal equipment held by the user or the terminal equipment held by the agency.
