For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation. In addition, although the division of the functional blocks is made in the device diagram, in some cases, it may be divided in blocks different from those in the device diagram.
The embodiment of the application provides a transaction payment method, a transaction payment device, transaction payment equipment and a storage medium based on a block chain. The transaction payment method based on the block chain can be applied to terminal equipment or a server, and the terminal equipment can be electronic equipment such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, a personal digital assistant and wearable equipment; the server may be a single server or a server cluster including a plurality of servers. The following explanation takes the application of the transaction payment method based on the blockchain to the server as an example.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a step of a transaction payment method based on a blockchain according to an embodiment of the present disclosure.
As shown in fig. 1, the block chain-based transaction payment method includes steps S101 to S105.
And step S101, acquiring a transaction request sent by a client, and verifying the transaction request.
The server is accessed into the blockchain network as a blockchain node, for example, the server is a distribution management node in the blockchain network. The blockchain network further comprises a plurality of service nodes, the distribution management node is used for performing distribution management on the transaction request sent by the client to distribute the transaction request to a target service node in the blockchain network, and the target service node is used for responding to the transaction request distributed by the distribution management node to complete a complete reimbursement process of the transaction request and complete a transaction.
It should be noted that the transaction request may include, but is not limited to, the requested information of the user's interest in moving funds, such as recharging, buying and selling, transferring, etc. For example, the transaction request may be request information for a user to recharge a certain amount of digital assets in a digital wallet; alternatively, the transaction request may be a request for information from the user to apply for a transfer to an outbound account. The transaction request of the embodiment of the application is not limited to the request of transaction circulation of legal currency, and also comprises the request of transaction circulation among non-real digital assets, such as virtual currency of Tadaemon USDT, TUSD and the like.
In one embodiment, the user generates the interest in the fund flow and causes the client to generate the transaction request through a triggering operation on the client. The client is, for example, a mobile phone or a PC computer, and the triggering operation is, for example, a click operation, a slide operation, a voice control operation, a verification operation, and the like, which is not limited in this embodiment. The transaction request generated by the client can be transmitted to the distribution management node through a preset Application Programming Interface (API), and the distribution management node can conveniently perform data interaction with the client through the API.
In one embodiment, the transaction request generated by the client is an encrypted transaction request. The transaction request carries a secret key and a merchant number, which may include a client identifier or a user identifier, and is one of the credentials for verifying the transaction request. The client encrypts the transaction request through a preset format, for example, concatenates the transaction requests in the form of key + vue, and encrypts the transaction request using an asymmetric algorithm, for example, an MD5 encryption algorithm and a key. It should be noted that the secret key is an independently set unique identification code, and the process of encrypting by the MD5 encryption algorithm is irreversible, so that the encrypted transaction request is difficult to crack, and the security of transaction payment is improved.
It can be understood that, after the distribution management node receives the encrypted transaction request, the encrypted transaction request needs to be decrypted and checked, for example, the encrypted transaction request is decrypted through a preset public key corresponding to the client, so as to obtain a plaintext of the transaction request. The transaction request may further include a plurality of items, such as the name of the transaction to be transacted, the category of the transaction, the number of the transaction, and the like. In the subsequent data interaction process of the transaction request and the related information thereof, for example, in the data interaction process of the distribution management node and the service node, the encrypted transaction request needs to be decrypted and checked, which is not described herein again.
In one embodiment, the distribution management node verifies the transaction request, including: and sending the transaction request to a plurality of service nodes in the block chain network so that the plurality of service nodes can verify the secret key and the merchant number in the transaction request. Specifically, each service node verifies the key and the merchant number in the transaction request, determines whether the key and the merchant number are correct, and obtains verification information; and the distribution management node determines the verification result of the transaction request according to the verification information sent by the plurality of service nodes. For example, when the number of the check information sent by the service nodes is greater than the preset number or the ratio is greater than the preset ratio, it is determined that the check result of the transaction request is passed, that is, the transaction request passes the check. The transaction request is verified through the service nodes in the block chain network, the transaction request is not needed to be verified through the distribution management node, the verification safety and fairness are improved, when the transaction request is not verified through the distribution management node, verification can be conducted through the service nodes near the distribution management node, and the feasibility is high.
And step S102, when the transaction request passes the verification, distributing the transaction request to a target service node in the block chain network according to a preset distribution rule.
After the transaction request is confirmed to pass the verification, the distribution management node records the transaction request, and distributes the transaction request to the target service node in the blockchain network according to the preset distribution rule so that the target service node can generate related collection information based on the transaction request, the cross-border transaction cost can be reduced, and the capital flow speed is increased. The transaction request is distributed according to the preset distribution rule, so that the response to the transaction request is quicker and the efficiency is higher.
In one embodiment, when the transaction request is verified, as shown in fig. 2, step S102 includes: substeps 1021 to substep S1022.
And a substep S1021, obtaining congestion information, reputation information and/or response speed of a plurality of service nodes in the block chain network.
The block chain network further comprises a plurality of service nodes, and the service nodes are used for receiving services corresponding to the transaction requests, such as receiving recharging services and transferring services. The congestion information is used for representing the access quantity of the transaction request, the credit information is used for representing the contract record of the service node responding to the transaction request, and the response speed is used for representing the duration of the service node responding to the transaction request.
It should be noted that the transaction requests that each service node can process within a period of time are limited, and when the access number of the transaction requests to be processed corresponding to one service node is larger, the number of queued transaction requests is larger, which indicates that the service node is more congested, and the congestion information of the service node is larger; when the business node processes the transaction request, disputes may be generated between the business node and a user who sends the transaction request, or complaints of the user are suffered, and when events which may violate the disputes, the complaints and the like occur on the business node, the credit information of the business node is influenced, and the higher the credit information of the business node is, the better the contract record of the business node responding to the transaction request is; the response speed of the service node is the time length required by the service node from the period of receiving the transaction request to the period of finishing the response (confirming collection) of the transaction request, namely the time length of the service node responding to the transaction request, and the faster the response speed of the service node is, the shorter the time length of the service node responding to the transaction request is, the better the effect is. After each service node completes a complete transaction service, the congestion information, the reputation information and/or the response speed and other related information are stored, so that the searching of the distribution management node and the intelligent distribution of the transaction request are facilitated.
And a substep S1022, selecting a target service node from the plurality of service nodes according to the congestion information, reputation information and/or response speed of the plurality of service nodes, and distributing the transaction request to the target service node.
The distribution management node can distribute the transaction request according to the congestion information of the service nodes, the service nodes with smaller congestion information have higher transaction request processing speed, the service nodes with higher credit information have better transaction request processing effect, and the service nodes with higher response speed have shorter transaction request processing time, so that the payment can be completed quickly.
In an embodiment, the service node corresponding to the minimum congestion information, the maximum reputation information and/or the minimum response speed in the plurality of service nodes is determined as the target service node, which is beneficial to ensuring the security of payment and quickly completing payment.
In another embodiment, priorities corresponding to the congestion information, the reputation information and the response speed are determined; selecting congestion information, credit information or response speed with higher priority as an influence factor; and selecting a target service node from the plurality of service nodes according to the influence factors. For example, if the priority corresponding to the response speed is the highest, the service node corresponding to the minimum response speed is selected to be determined as the target service node, so as to improve the timeliness of payment.
In one embodiment, a first preset coefficient corresponding to congestion information is determined, and a first score of each service node is calculated according to the first preset coefficient and the congestion information of a plurality of service nodes; determining a second preset coefficient corresponding to the credit information, and calculating a second score of each service node according to the second preset coefficient and the credit information of the plurality of service nodes; determining a third preset coefficient corresponding to the response speed, and calculating a third score of each service node according to the third preset coefficient and the response speeds of the plurality of service nodes; and selecting a target service node from the plurality of service nodes according to the first score, the second score and the third score of each service node. The first preset coefficient, the second preset coefficient and the third preset coefficient can be set according to actual conditions and can be positive numbers or negative numbers. And adding the first score, the second score and the third score of each service node, and selecting the service node with the lowest total score or the highest total score as a target service node, so that the distribution management node distributes the transaction request to the service node with high stability and efficiency, and payment transaction between the user and the service payment chain is facilitated.
Illustratively, the first preset coefficient is 0.5, the second preset coefficient is-0.3, and the third preset coefficient is 0.4, so that the traffic node with smaller congestion information has a higher speed of processing the transaction request, and the first score of each traffic node is less dominant; the higher the credit information is, the better the effect of the business node on processing the transaction request is, and the second preset coefficient is a negative number, so that the second score of each business node is small; the service node with higher response speed has shorter duration for processing the transaction request, and the third fraction of each service node is smaller; the total score of each service node is the sum of the first score, the second score and the third score, so that the service node with the lowest total score is selected as the target service node, and the payment transaction effect is good.
In an embodiment, when the performance parameter of the target service node is less than or equal to the preset performance parameter and the current duration of the target service node responding to the transaction request is greater than or equal to the preset duration, a new target service node is selected from the plurality of service nodes, and the transaction request is distributed to the new target service node. The performance parameter at least includes one of the operating speed of the CPU, the memory size, the disk write performance, the disk read performance, and the like, and the preset performance parameter and the preset duration may be flexibly set by the user, which is not specifically limited in this embodiment.
It should be noted that the set allocation rule includes that the distribution management node can switch any service node, which is beneficial to distributing and controlling the service to be traded. If the distribution management node dispatches the transaction request to the service system A, the service system A is found not to reach the preset performance parameters or the server is down, the processing of the service can be temporarily interrupted, and the service system B can be quickly switched to at the moment, so that the whole service of the distribution management node is not influenced and can be normally used.
In one embodiment, after the distribution management node distributes the transaction request to the target service node in the blockchain network, the target service node generates relevant collection information based on the transaction request. The collection information comprises a collection mode, a collection amount, a receiver, a collection account number, a collection address link and the like supported by the target service node, the collection mode comprises payment modes such as union pay, WeChat and Paibao, and the target service node also needs to return the generated collection information to the distribution management node.
And step S103, acquiring collection information returned by the target service node based on the transaction request, and generating a payment page according to the collection information.
And the distribution management node acquires the collection information returned by the target service node based on the transaction request, records the collection information, and then generates a payment page by utilizing the information such as collection mode, collection amount, a receiver, a collection account number, a collection address link and the like in the collection information. The data interaction between the distribution management node and the target service node is carried out based on the appointed application program interface API.
Step S104, sending the payment page to the client for the client to display the payment page, and responding to the payment operation of the user on the payment page to generate payment information.
The distribution management node returns the payment page to the client through a preset application program interface API, the client displays the payment page on the display interface, and generates payment information in response to payment operation of the user on the payment page. The payment information comprises a payment mode, a collection amount, a payer, payment time, a payment account number and the like, and the payment mode is the same as the collection mode supported by the target service node and comprises payment modes such as Unionpay, WeChat, Paibao and the like. The payment operation of the user on the payment page comprises a code scanning operation, a password input operation, a fingerprint code input operation, a face feature input operation and other payment operations.
Step S105, the payment information sent by the client is verified, when the payment information passes the verification, the balance information of the transaction request is generated, and the balance information is broadcasted in the block chain network.
The payment information comprises a transaction request, collection information and payment information, the transaction pool of the target service node records the payment information, the target service node can quickly know the complete payment process of the payment transaction through the payment information recorded in the transaction pool, effective recording is carried out when cross-border payment or recharging conversion between legal currency and digital assets is carried out, and the reasonability and the safety of asset circulation are guaranteed.
In one embodiment, the verifying the payment information sent by the client comprises: the distribution management node sends the payment information sent by the client to a plurality of service nodes in the block chain network, so that the plurality of service nodes can check the payment information. When the plurality of service nodes in the block chain network receive the payment information issued by the distribution management node, the payment information can be verified. Illustratively, each business node enters a bank transfer system through a network interface to verify a payment account contained in payment information, whether a collection account and a payment amount are correct, whether the payment account has enough payment amount, whether a target business node confirms collection and the like, and a verification result about the payment information is sent to a distribution management node, the distribution management node generates receipt and payment information of a transaction request when confirming that the payment information passes verification, and issues the receipt and payment information to a block chain network, so that the phenomena of fake payment information and fake payment information can be effectively avoided, and the security of transaction payment is improved.
