Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
At present, the network transfer settlement mode brings convenience and also has higher risk. In particular, since commodity transactions and money payments are performed through the internet, and various threats such as information tampering and domain name tampering exist in the internet, commodity transactions and money payments performed based on the internet are also faced with various threats. Although transaction systems of financial institutions such as banks are more secure, the security and tamper resistance of the existing financial transaction systems are still further improved because the security of the transaction systems is threatened by computer network devices, viruses, hacking and the like. To this end, the embodiments of the present application disclose a transaction method, apparatus, device, and readable storage medium to improve the security and tamper resistance of transactions.
Referring to fig. 1, an embodiment of the present application provides a first transaction method applied to a node in a blockchain system, including:
s101, receiving transaction information sent by a user; the transaction information includes at least: transaction authorization code, transaction amount, collection bank card number, and transaction signature information; the transaction authorization code is generated and fed back to the user after the identity information, the payment bank card number and the payment password submitted by the Unionpay clearing center in the blockchain system pass verification.
In this embodiment, the transaction authorization code indicates that the transaction information sent by the current user is authorized by the banked clearinghouse, so that the identity of the user who sends the transaction information can be considered as the true identity.
The transaction amount is the amount that the current transaction needs to pay. The collection bank card number is the bank card account number of the seller. The transaction signature information is the signature information of the current transaction information, and the generation of the transaction signature information can adopt the existing signature algorithm. It should be noted that, the transaction information generally further includes user identification information and remark information of the current transaction; the user identification information may be a virtual address used by the user; the remark information is used for briefly describing the transaction or describing the special features of the transaction. Of course, other available information may be added to the transaction information.
The transaction authorization code is generated and fed back to the user after the verification of the identity information, the payment bank card number and the payment password submitted by the Unionpay clearing center in the blockchain system is passed, so that the user submits the identity information, the payment bank card number and the payment password to the Unionpay clearing center before sending the transaction information, and the identity information can be the identity card number and other information on resident identity cards, so that the user can be a natural person, namely a buyer.
In this embodiment, the information submitted by the user to the Unionpay clearing center further includes: the total amount in the payment bank card, the limit of the single transaction, the validity period of the information currently submitted, etc. If the identity information, the payment bank card number and the payment password submitted by the user pass verification, the Unionpay clearing center returns the corresponding transaction authorization code to the user.
When the Unionpay clearing center receives the identity information, the payment bank card number and the payment password, the identity information, the payment bank card number and the payment password of the user stored in advance can be compared with the received identity information, the payment bank card number and the payment password one by one, and if the identity information, the payment bank card number and the payment password are not different, the verification is passed; if any information does not correspond, the verification is not passed. After verification, the Unionpay clearing center feeds back the transaction authorization code to the user, so that the user can send transaction information to nodes in the blockchain system.
The information fed back to the user by the Unionpay clearing center can comprise: transaction authorization codes, single transaction limits, available amounts in a payment bank card, validity periods of information currently fed back, etc.
S102, checking the transaction signature information, and if the verification is passed, adding the transaction signature information into a notarized competition pool of the transaction information.
Specifically, when a user carries out a transaction based on a certain node in the blockchain system and sends transaction information, any node in the blockchain system can receive the transaction information, the node receiving the transaction information can verify the transaction signature information, if the verification is passed, the transaction information is indicated to be normal transaction information, and then the nodes can be added into a notarized competition pool of the transaction information.
And S103, if the node is selected in the notarization competition pool by the blockchain system by adopting a consensus mechanism, after notarizing the transaction information, transmitting the transaction information to the Unionpay clearing center so that the Unionpay clearing center pays the transaction amount to the collection bank card number according to the transaction authorization code.
In this embodiment, if a node joins in a notarized competition pool of transaction information, it indicates: the node is willing to prove the authenticity of the transaction information. Because the node for proving the authenticity of the transaction information is generally one, if the number of the nodes added into the notarization competition pool is larger than one, the blockchain system can adopt a consensus mechanism to select one node in the notarization competition pool as the node for notarizing the transaction information, and the method for selecting the node is generally as follows: and selecting the node with the highest calculation efficiency in the notarization competition pool as the node for notarizing the transaction information. The specific selection method can refer to the existing ethernet pow consensus mechanism, so this embodiment is not described herein.
It can be seen that the present embodiment provides a transaction method, which completes a transaction in a blockchain system in a bank transfer settlement manner, wherein a consensus mechanism in the blockchain system is adopted to avoid tampering of the transaction, thereby improving transaction security; and, add the Unionpay clearing center into the block chain system, is equivalent to having drafted the armor of tamper-proof for the Unionpay clearing center, therefore has improved the payment security too. The present application increases the security and tamper resistance of transactions. Meanwhile, the problem of fund damage caused by virtual coin value fluctuation can be avoided, and economic benefits of both transaction parties are guaranteed. Therefore, the application not only improves the transaction safety and tamper resistance, but also avoids the defects of the block chain system, and can ensure the economic benefits of both transaction parties.
The embodiment of the application discloses a second transaction method, and compared with the previous embodiment, the technical scheme of the embodiment is further described and optimized.
Referring to fig. 2, a second transaction method is provided in an embodiment of the present application, applied to a node in a blockchain system, including:
s201, receiving transaction information sent by a user; the transaction information includes at least: transaction authorization code, authorization number of transaction authorization code, transaction amount, collection bank card number and transaction signature information; the transaction authorization code is generated and fed back to the user after the identity information, the payment bank card number and the payment password submitted by the Unionpay clearing center in the blockchain system pass verification;
in this embodiment, the information submitted by the user to the Unionpay clearing center further includes: the number of authorizations of the transaction authorization code applied by the user. That is, the user applies for the authorization number of the current transaction authorization code while applying for the transaction authorization code to the Unionpay clearing center. The authorization times are obtained by applying the user to the Unionpay clearing center, and if the identity information submitted by the user, the payment bank card number and the payment password are all verified, the Unionpay clearing center agrees to the authorization times applied by the user.
In this embodiment, the authorization number of the transaction authorization code indicates that the current transaction information can be authenticated by several nodes. For example: if the authorization times of the transaction authorization code is 2, two nodes are required to participate in notarization of the transaction information; if the authorization times of the transaction authorization code is 1, indicating that a node is required to participate in notarizing the transaction information; if the authorization number of the transaction authorization code is 0, the fact that any node is not required to participate in notarizing the transaction information is indicated. It should be noted that, the number of times of authorization of the transaction authorization code is generally set to "1".

s206, if the node is selected in the notarization competition pool by the block chain system by adopting a consensus mechanism, notarizing the transaction information;
s207, transmitting the transaction information to a Unionpay clearing center so that the Unionpay clearing center pays the transaction amount to the collection bank card number according to the transaction authorization code;
and S208, returning the message which is not checked by the transaction signature information.
In this embodiment, if the transaction signature information is not verified, a message that the transaction signature information is not verified is returned, so that the user modifies the transaction information according to the message. The method for judging whether the transaction information is notarized according to the authorization times of the transaction authorization code can be as follows: and judging whether the notarization of the transaction information can obtain notarization payment. It should be noted that, for the node participating in the notarization of the transaction information, the user needs to pay the corresponding notarization payment thereto. Therefore, the node which receives the transaction information can autonomously select whether to participate in the notarization of the current transaction information; if so, adding the transaction information into the notarized competition pool so that the blockchain system adopts a consensus mechanism to select in the notarized competition pool.
Specifically, if the authorization number of the transaction authorization code is "1", it indicates that a node is required to participate in the notarization of the transaction information, that is, the node participating in the notarization of the transaction information can obtain notarization payment; if the authorization number of the transaction authorization code is 0, it indicates that any node is not required to participate in the notarization of the transaction information, and if the node notarizes the transaction, the node participating in the notarization of the transaction information cannot obtain notarization payment.
It should be noted that other implementation steps in the present embodiment are the same as or similar to those in the above embodiment, so that the description of the present embodiment is omitted here.
It can be seen that the present embodiment provides a transaction method, which completes a transaction in a blockchain system in a bank transfer settlement manner, wherein a consensus mechanism in the blockchain system is adopted to avoid tampering of the transaction, thereby improving transaction security; and, add the Unionpay clearing center into the block chain system, is equivalent to having drafted the armor of tamper-proof for the Unionpay clearing center, therefore has improved the payment security too. The present application increases the security and tamper resistance of transactions. Meanwhile, the problem of fund damage caused by virtual coin value fluctuation can be avoided, and economic benefits of both transaction parties are guaranteed. Therefore, the application not only improves the transaction safety and tamper resistance, but also avoids the defects of the block chain system, and can ensure the economic benefits of both transaction parties.
The embodiment of the application discloses a third transaction method, and compared with the previous embodiment, the technical scheme of the embodiment is further described and optimized.
Referring to fig. 3, an embodiment of the present application provides a third transaction method applied to a node in a blockchain system, including:
s301, receiving transaction information sent by a user; the transaction information includes at least: transaction authorization code, authorization number of transaction authorization code, transaction amount, collection bank card number and transaction signature information; the transaction authorization code is generated and fed back to the user after the identity information, the payment bank card number and the payment password submitted by the Unionpay clearing center in the blockchain system pass verification;
s302, checking the transaction signature information, and judging whether the check is passed; if yes, then execute S303; if not, executing S308;
s303, broadcasting transaction information;
s304, judging whether the notarized transaction information can obtain notarized rewards according to the authorized times; if yes, then execute S305; if not, no operation is performed;
s305, adding a notarization competition pool of transaction information;
s306, if the node is selected in the notarization competition pool by the block chain system by adopting a pow consensus mechanism, notarizing the transaction information by adopting an Ethernet mode;
s307, the transaction information and the self node information are sent to the Unionpay clearing center, so that the Unionpay clearing center checks the node signature information in the self node information, and if the node signature information passes the check, the transaction amount is paid to the collection bank card number according to the transaction authorization code;
and S308, returning the message which is not checked by the transaction signature information.
In this embodiment, the node notarizing the transaction information is in an ethernet mode, and the blockchain system selects a node in a notarizing competition pool to notarize the transaction information by using a pow consensus mechanism. The specific implementation process may refer to the prior art, so this embodiment is not described herein.
In this embodiment, when the node sends the transaction information to the banked clearing center, the node also sends the own node information and the valid period of the current information, where the own node information includes: node identification information, namely node virtual addresses; a bank card number for receiving the notarization payment; node signature information of the current node, and the like. Therefore, after the Unionpay clearing center receives the information, the node signature information is checked first, and if the node signature information passes the check, the transaction amount is paid to the collection bank card number according to the transaction authorization code.
Specifically, the Unionpay clearing center also obtains the node virtual address of the node from other nodes in the blockchain system, and compares the virtual address fed back by the other nodes with the virtual address sent by the current node; and if the two are consistent, indicating that the virtual address sent by the current node is correct.
It should be noted that, the Unionpay clearing center pays the transaction amount to the collection bank card number according to the transaction authorization code, including: the Unionpay clearing center verifies whether the transaction authorization code is valid; if so, the transaction amount is paid to the collection bank card number.
Specifically, the Unionpay clearing center checks whether the transaction authorization code is valid, including: the Unionpay clearing center checks whether the format of the transaction authorization code is correct; comparing whether the transaction authorization code in the transaction information sent by the current node is consistent with the transaction authorization code fed back by the Unionpay clearing center for the user; whether the current information sent by the current node is in a valid period, etc.
It should be noted that, after the Unionpay clearing center pays the transaction amount to the collection bank card number according to the transaction authorization code, the method further comprises: the Unionpay clearing center checks whether the authorized times are valid; if yes, paying the public card payment to the bank card number of the node for receiving the public card payment; wherein, the notarization reward is the notarization reward obtained by the node notarization transaction information; the bank card number for receiving the notarization payment exists in the own node information.
Specifically, the checking of whether the authorized times are valid by the Unionpay clearing center comprises the following steps: comparing whether the authorization times in the transaction information sent by the current node are consistent with the authorization times applied by the user to the Unionpay clearing center.
It can be seen that the present embodiment provides a transaction method, which completes a transaction in a blockchain system in a bank transfer settlement manner, wherein a pow consensus mechanism in the blockchain system is adopted to avoid tampering of the transaction, thereby improving transaction security; and, add the Unionpay clearing center into the block chain system, is equivalent to having drafted the armor of tamper-proof for the Unionpay clearing center, therefore has improved the payment security too. The present application increases the security and tamper resistance of transactions. Meanwhile, the problem of fund damage caused by virtual coin value fluctuation can be avoided, and economic benefits of both transaction parties are guaranteed. Therefore, the application not only improves the transaction safety and tamper resistance, but also avoids the defects of the block chain system, and can ensure the economic benefits of both transaction parties.
