It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.
Some embodiments of the present application provide a block chain-based sub-account transaction processing method, in which a plurality of accounts owned by a user are constructed in the form of one main account and a plurality of sub-accounts, a sub-account address corresponding to a sub-account includes a main account address corresponding to the main account, and the user only needs to memorize a private key corresponding to the main account, and can implement an operation on the sub-account by using one private key in combination with the main account address and the sub-account address. Therefore, the plurality of accounts of the user do not need to be distinguished by the private keys, the plurality of accounts can adopt the same private key, the user only needs to remember one private key, and any sub-account of the user can be operated through the private key, so that the condition that the plurality of private keys are mixed or forgotten is avoided.
Before the sub-account transaction processing is performed by the method provided by the embodiment of the present application, a sub-account of a user is first created in a blockchain through the following operations of steps S1-S4, which specifically includes:
step S1: the terminal acquires a main account address corresponding to a main account of a user.
When a user needs to create a sub-account in the blockchain, the user can submit a main account address of the user to the terminal, and the main account address can be an account number of a main account selected by the user. And the terminal receives the primary account address submitted by the user.
Step S2: and the terminal generates a sub-account address according to the main account address.
The sub-account address is generated based on the primary account address so that when a subsequent sub-account transfer is made, it can be determined whether the sub-account is indeed the account owned by the user originating the transfer request based on the primary account address and the sub-account address. Therefore, the account of the user can be identified in time under the condition that the account of the user is stolen by other people, and the loss of the account balance of the user is avoided.
The terminal specifically generates the sub-account address through the following operations of steps S21 and S22, and specifically includes:
step S21: the terminal generates a temporary string.
The embodiment of the application can generate a random number through the random number generator, and the random number is determined as the temporary character string. Alternatively, the user inputs random information to the terminal, where the random information may be user information such as the user's name, nickname, telephone number, and address, or a character sequence randomly input by the user. As long as it is ensured that the random information entered by the user is different for each sub-account created. The terminal acquires random information input by a user, and performs hash operation on the random information to obtain a temporary character string.
A random number may be generated each time as a temporary string, or a hash operation may be performed on random information input by a user to obtain a temporary string. This ensures that the account address of each sub-account of the user is different.
Step S22: and adding a temporary character string at a preset position of the character sequence of the main account address by the terminal to obtain the sub-account address.
After generating the temporary character string through step S21, the terminal adds the temporary character string at a preset position of the character sequence of the primary account address, which may be a start position, an end position, an intermediate position, or the like of the character sequence of the primary account address. And adding the temporary character string into the address of the main account to obtain a new address, and taking the new address as the address of the sub-account corresponding to the sub-account which needs to be created currently.
The sub-account address is generated by adding a temporary character string in the main account address, so that the main account address is included in the sub-account address, and whether the sub-account is really the account owned by the user who initiates the transfer request can be determined according to the main account address and the sub-account address when the sub-account transfer is subsequently carried out. After the sub-account address is generated, the sub-account is created in the blockchain by the operation of step S3 as follows.
Step S3: and the terminal sends an account creation request to the block link point, wherein the account creation request comprises the generated sub-account address.
After the terminal generates the sub-account address, an account creation request is sent to the block link point, and the generated sub-account address is carried in the account creation request.
Step S4: and the block chain node receives an account creation request sent by the terminal and creates a sub-account of the user in the block chain.
The block link node receives an account creation request sent by the terminal, where the account creation request includes one or more of user information such as a user's name, phone, URL (Uniform Resource Locator), and the like, and includes the generated sub-account address. And storing the corresponding relation between the sub-account address and the user information in each block chain point. And storing the corresponding relation between the sub-account address and the user information in the block chain node to complete the creation process of the sub-account, wherein the block chain node can return a successful creation notification to the terminal.
In other embodiments of the present application, when a user needs to create a sub-account in a blockchain, after acquiring a primary account address corresponding to a primary account of the user, the terminal may also directly send an account creation request to a blockchain link point, where the account creation request includes the primary account address of the user and user information. After the block link point receives the account creation request, a sub-account address is generated by the block link point in the manner of step S2, and then. And storing the corresponding relation between the sub-account address and the user information in each block chain point, completing the creation process of the sub-account, and returning the sub-account address corresponding to the sub-account to the terminal of the user.
Each sub-account owned by the user may be created in a blockchain in the manner described above. After creating the sub-account, the user can perform a transfer operation on the sub-account. Referring to FIG. 1, the transfer operation is performed on the sub-account, specifically by the following operations of steps S101-S106.
Step S101: the terminal receives a private key submitted by a user and transfer information corresponding to the sub-account, wherein the transfer information comprises a sub-account address corresponding to the sub-account, and the sub-account address comprises a main account address corresponding to a main account of the user.
In the embodiment of the application, when a user creates a main account, a terminal generates a key pair by a preset asymmetric encryption algorithm according to the address of the main account of the user, and stores a public key included in the key pair in the terminal. The private key is remembered by the user himself. The predetermined asymmetric encryption Algorithm may be rsa (rsa Algorithm), DSA (Digital Signature Algorithm), ECC (Elliptic encryption Algorithm), etc.
When the user needs to transfer accounts from the sub-accounts to other accounts, the terminal displays a transfer interface, the user submits the sub-account address, the destination account address and the transfer amount corresponding to the sub-accounts in the transfer interface, and the private key of the user is input. The transfer information may include a sub-account address, a destination account address, and a transfer amount.
Step S102: and the terminal signs the transfer information through a private key submitted by the user to obtain a transfer information ciphertext.
And the terminal encrypts the transfer information such as the sub account address, the target account address, the transfer amount and the like through a private key input by the user to obtain a transfer information ciphertext.
Step S103: and the terminal sends a transfer request corresponding to the sub-account to the block chain node, wherein the transfer request comprises a transfer information ciphertext and a pre-stored public key.
And the terminal acquires a pre-stored public key from the local, generates a transfer request according to the public key and the transfer information ciphertext generated in the step S102, and sends the transfer request to the block chain node.
Step S104: and the block chain node receives a transfer request corresponding to the sub-account sent by the terminal of the user, and acquires the sub-account address corresponding to the sub-account and the main account address of the user according to the transfer request.
Specifically, the sub-account address and the main account address are obtained through the following operations of steps S1041 to S1043:
step S1041: and the block chain node acquires the public key and the transfer information ciphertext from the transfer request.
Step S1042: and the block chain node decrypts the transfer information ciphertext through the public key to obtain transfer information, wherein the transfer information comprises a sub-account address.
And the block chain node decrypts the transfer information ciphertext through the public key to obtain transfer information such as a sub-account address, a target account address, a transfer amount and the like.
Step S1043: and the block chain node calculates the public key through a preset asymmetric encryption algorithm to obtain the main account address of the user.
The public key is obtained by calculating the main account address of the user through the preset asymmetric encryption algorithm, so that the main account address of the user can be obtained by reversely running the public key through the preset asymmetric encryption algorithm.
The sub-account address corresponding to the transfer request and the main account address of the user can be obtained through the transfer request, so that whether the current sub-account is the account owned by the user or not can be determined according to the sub-account address and the main account address.
Step S105: and the block chain node determines whether the sub account is a sub account owned by the user according to the sub account address and the main account address.
And comparing the sub-account address with the main account address by the block chain node, and determining whether the main account address is included in the sub-account address. Specifically, the blockchain node traverses from a first character of the sub-account address, compares whether the first character of the sub-account address is the same as a first character of the main account address, and if so, compares whether a second character of the sub-account address is the same as a second character of the main account address. If the first character of the sub-account address is not the same as the first character of the primary account address, comparing whether the second character of the sub-account address is the same as the first character of the primary account address. And if the characters of the sub-account address and the main account address are traversed out and all the characters of the main account address are included in the sub-account address, determining that the sub-account address includes the main account address, and further determining that the sub-account is the sub-account owned by the user. If it is determined that the sub-account address does not include all of the characters of the primary account address, then it is determined that the sub-account is not a sub-account owned by the user.
Through the operation, whether the sub account which initiates the transfer request at present is the sub account owned by the user can be accurately determined, and if the sub account is determined not to be the sub account owned by the user, the fact that the user wants to transfer money from the sub account of other people is indicated, and property safety of other people is damaged. The method and the device for determining the sub-account can determine whether the sub-account is the sub-account owned by the current user. Therefore, the account of the user can be identified in time under the condition that the account of the user is stolen by other people, and the loss of the account balance of the user is avoided.
Since the sub-account addresses of the user are in the form of the main account address plus the temporary character string, the main account address of the user is included in the address of each sub-account of the user, and therefore, whether the sub-account is the sub-account owned by the current user can be determined by determining whether the main account address of the user is included in the address of the sub-account which currently initiates the account request. Therefore, the account of the user can be identified in time under the condition that the account of the user is stolen by other people, and the loss of the account balance of the user is avoided.
Step S106: and if the block chain node determines that the sub-account is the sub-account owned by the user, performing transfer processing on the transfer request.
If the block link point determines that the sub-account is a sub-account owned by the user, the transfer may be made. Specifically, according to the sub-account address and the transfer amount included in the transfer information obtained in step S1042, the transfer amount is subtracted from the account balance corresponding to the sub-account address. And adding the transfer amount to account balance corresponding to the destination account address according to the destination account address and the transfer amount included in the transfer information.
After the transfer is carried out from the sub account to the destination account in the mode, a transfer success notice is generated according to the sub account address, the transfer amount and the destination account address, and the transfer success notice comprises the sub account address, the transfer amount, the destination account address and prompt information for prompting the transfer success. And sending a transfer success notice to the terminal of the user so that the user can know the balance change condition of the sub-account in real time.
After the transfer of the sub-account is completed in the above mode, a transfer record corresponding to the transfer request is generated according to the transfer amount, the destination account address and the sub-account address. And storing the corresponding relation between the sub-account address and the transfer record in each block chain node. Based on the traceable and non-tamperable characteristics of the block chain, the transfer records of the sub-accounts are stored in the block chain link points, the authenticity of the transfer records of the sub-accounts can be ensured, and account book counterfeiting is avoided.
And if the block link point determines that the sub-account is not the sub-account owned by the user, the transfer operation cannot be carried out, the transfer request is discarded, and a transfer failure notification is sent to the terminal of the user. In this embodiment, the block link point may further obtain, according to the sub-account address, a URL of the real user of the sub-account from account information corresponding to the sub-account address. And sending warning information to the real user of the sub-account according to the acquired URL, wherein the warning information is used for prompting that other people try to transfer accounts from the sub-account, so that the user is prompted that the sub-account has a safety risk, the user can timely perform freezing operation on the sub-account, or the balance in the sub-account is transferred away, or own keys are modified, and the like, so that the loss of the account balance of the user is avoided when the sub-account is stolen.
In the embodiment of the application, a plurality of accounts owned by a user are constructed into a form of one main account and a plurality of sub-accounts, and the sub-account addresses corresponding to the sub-accounts comprise the main account address corresponding to the main account. The user only needs to memorize the private key corresponding to the main account, and the operation on the sub-account can be realized by combining the address of the main account and the address of the sub-account through one private key. Therefore, the multiple accounts of the user do not need to be distinguished by keys, the multiple accounts can adopt the same key, the user only needs to remember one private key, and any sub-account of the user can be operated by the private key, so that the condition that the multiple keys are mixed or forgotten is avoided. And the block chain node acquires the sub-account address and the main account address of the user according to the transfer request, and determines whether the current sub-account is the sub-account owned by the user or not according to the sub-account address and the main account address. The transfer processing is carried out only after the sub-account is determined to be the sub-account owned by the user, so that the account of the user can be identified in time under the condition that the account is stolen by other people, and the loss of the account balance of the user is avoided.
