The first terminal and the second terminal may be computer devices, including mobile phones, tablet computers, notebook computers, palm computers, smart phones, mobile internet devices (MID, mobile internet device), POS (Point Of sale) devices, wearable devices (e.g., smart watches, smart bracelets, etc.), and the like.
In practical applications, in a scenario where the above data processing system may be used to trade options of various targets, as shown in fig. 1d, fig. 1d is a schematic view of an interaction process of each device in the data processing system provided in this embodiment of the present application, and if the king needs to purchase the option, the terminal of the king Wang Duiying may be referred to as a first terminal, and if xiao Li sells the option, the terminal of the king Li Duiying may be referred to as a second terminal. Before the small Wang Xiang block link point system sends option trade data, a user (for example xiao Li) for selling options can upload options to be sold to the block link node system through the second terminal, namely, the options to be uploaded are stored by the block link point system, and at least one candidate option is obtained. When the king needs to acquire (purchase) options, first, the king may initiate option trading data of purchasing options through an application that performs option trading, where the option trading data may include a value of an electronic resource that acquires a unit number of option pre-pays, a number of options that need to be acquired, and so on. Then, after the blockchain node system obtains the option trading data of the purchased options, the legality of the terminal of the king is verified according to the option trading data, for example, whether the number of options required to be purchased by the king is in accordance with the regulations, for example, whether the number of options is greater than zero and less than the total number of options belonging to the institution in which the king is located, whether the number of electronic resources required to be paid out for obtaining the options of unit number is in accordance with the regulations, for example, whether the number of electronic resources required to be paid out for obtaining the options of unit number is greater than or equal to the average value of the electronic resources required to be paid out for obtaining the options of unit number, and so on. If the terminal of the king has validity, for example, the number of options that the king needs to purchase and the electronic resources required for purchasing the options of the unit number meet the regulations, at least one candidate option for trading is read from the blockchain, wherein the candidate option includes all options that need to be sold, for example, the options sold by xiao Li or the options sold by other employees of the institution where the king is located, such as the staff of the king, xiao Tang, xiao Chen, and the like. Then, a candidate option matching the option trading data is identified from the at least one candidate option, as a target option, the target option is transferred to the terminal of the king, and the electronic resource corresponding to the target option is transferred from the terminal of the king to the terminal of xiao Li. In this way, the blockchain node system realizes option trading by identifying options matched with option trading data of the first terminal, and the option trading can be realized by only uploading option information to be transferred for an option transfer party (a seller) and only uploading option information to be acquired for an option acquirer (a buyer), so that the option trading efficiency is improved, and the safety and fairness of the option trading are improved.
Referring to fig. 2, fig. 2 is a flow chart of a data processing method based on a blockchain, which is applied to a node in a blockchain network and may refer to a computer device; as shown in fig. 2, the data processing method may include the following steps S101 to S104.
S101, acquiring option trading data.
Here, option trading data is used for the first terminal to obtain options from the blockchain. The first terminal refers to a terminal held by a user who needs to acquire an option, and the subject matter of the option refers to assets selected for purchase or sale, including shares, stocks, government bonds, currencies, stock indices, commodity futures, and the like. For example, an option of a share of a certain organization may be traded, and the first terminal is the terminal held by the user who wants to acquire the option of the share. The option trading data may include, for example, a value of an electronic resource that obtains a unit number of option pre-payouts, a number of options that need to be obtained, a time of the option that needs to be obtained, and identity information of a user holding the first terminal, etc. In the embodiments of the present application, options of any kind of subject matter are illustrated, for example, the options in the embodiments of the present application may refer to one of options corresponding to shares of a certain institution, options corresponding to stocks of a certain institution, options corresponding to government bonds of a certain institution, or options of other subject matter.
Optionally, when each block in the blockchain is generated, referring to fig. 3, fig. 3 is a schematic diagram of an option trading information uplink process provided in the embodiment of the present application, when a node where the blockchain is located receives input information (option trading data), the input information is checked, after the checking is completed, the input information is stored in a memory pool, and a hash tree for recording the input information is updated; then, updating the update time stamp to the time of receiving the input information, trying different random numbers, and calculating the characteristic value for a plurality of times, so that the calculated characteristic value can meet the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
wherein SHA256 is a eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.
Thus, when the random number meeting the formula is calculated, the information can be correspondingly stored to generate the block head and the block main body, and the current block is obtained. And then, the node where the blockchain is located sends the newly generated block to other nodes in the blockchain node system where the newly generated block is located according to the node identification of other nodes in the blockchain node system, the other nodes verify the newly generated block, and the newly generated block is added into the blockchain stored by the newly generated block after the verification is completed.
And S102, verifying the validity of the first terminal according to the option transaction data.
Here, the validity of the first terminal may be used to indicate that option trade data of the first terminal is compliant with the specification. For example, the first terminal may acquire the number of electronic resources of the preset expenditure of the option of the unit number, the number of options to be acquired, and the like, which meet the regulations. The validity of the first terminal can be verified according to the value of the electronic resource of the option pre-expenditure of the unit number, the number of options to be acquired, and the like. For example, when the value of the electronic resource for acquiring the option pre-expenditure of the unit number is greater than or equal to the average value of the electronic resource for acquiring the option pre-expenditure of the unit number, determining that the first terminal has validity; or when the number of options to be acquired is greater than zero and less than the total number of options belonging to the institution where the first terminal is located, determining that the first terminal has validity; or when the value of the electronic resource for acquiring the option pre-expenditure of the unit number is greater than or equal to the average value of the electronic resource for acquiring the option pre-expenditure of the unit number, and the number of the options to be acquired is greater than zero and less than the total number of the options belonging to the institution where the first terminal is located, determining that the first terminal has validity, and the like.
Optionally, for example, if the institution where the first terminal is located specifies that the option belonging to the same user cannot be greater than the upper threshold, verifying the validity of the first terminal according to the option trade data may further include: acquiring the option quantity of the user corresponding to the first terminal, and determining that the first terminal has validity if the sum of the option quantity of the user corresponding to the first terminal and the option quantity required to be acquired by the first terminal is smaller than or equal to the upper limit of the threshold; if the first terminal is greater than the upper threshold, determining that the first terminal is not legal, and the like.
And S103, if the first terminal has validity, reading at least one candidate option for trading from the blockchain.
Here, if the first terminal has legitimacy, reading at least one candidate option for trading from the blockchain; if the first terminal does not have the validity, prompt information for prompting the first terminal to modify option transaction data can be generated. For example, the reminder may include "number of options not in compliance with the prescription," "price of options not in compliance with the prescription," and the like, and the user holding the first terminal may modify the option trading data according to the reminder such that the modified option trading data is in compliance with the prescription, thereby performing the step of reading at least one candidate option for trading from the blockchain.
In a specific implementation, the candidate options stored in the blockchain may be generated by the computer device according to option information to be transferred uploaded by the second terminal for option transfer in the option trading application, for example, the option information to be transferred may include a value of an electronic resource required to be paid for a unit number of options, a number of options required to be sold, a time of the option required to be sold, and so on. And the blockchain node system stores option information to be transferred, which is uploaded by the second terminal, to obtain candidate options. It may be understood that the number of the second terminals may be multiple, that is, the users corresponding to the multiple second terminals all need to sell different options, and then the option information to be transferred uploaded by each second terminal may be displayed on the interface corresponding to the option trading application, as shown in fig. 4, fig. 4 is a schematic diagram of a display interface of options to be transferred provided in the embodiment of the present application, fig. 4 includes 7 options to be transferred, for example, the number of electronic resources required to be paid for obtaining the option 1 of unit number is 12.960, and the number of the option 1 is 13.4k, where k is a metering unit; the number of electronic resources required to be paid out for acquiring the option 2 with the unit number is 12.980, the number of the option 2 is 1.429M, M is also a measuring unit, and M is larger than K. It can be known that the same option to be transferred may include options to be transferred uploaded by a plurality of second terminals, and the values of the electronic resources required to be paid out for obtaining the unit number of options to be transferred are equal in the options to be transferred uploaded by the plurality of second terminals. For example, the number of options 1 is 13.4K, including the sum of the number of options uploaded by the 3 second terminals, and the number of electronic resources required to be paid out for obtaining the number of options is 12.960 in the options uploaded by the 3 second terminals.
In one possible implementation manner, for example, when there is no option transferred by the second terminal or the options to be transferred of the second terminal are transferred completely, the first terminal needs to acquire the options, and then the option trading data of the first terminal may be displayed on the interface corresponding to the option trading application. The number of the first terminals may be one or more, for example, when the number of the first terminals is plural, then option trading data of the plural first terminals is displayed, as shown in fig. 5, fig. 5 is a schematic diagram of a display interface of option trading data provided in the embodiment of the present application, where fig. 5 includes option trading data of the plural first terminals, for example, the option trading data of the first terminal 11 includes a value 12.940 of electronic resources that is pre-paid for acquiring a unit number of option 1, and the number of option 1 is 639.8K. By displaying the option trading data of the first terminal, a user (option seller) who needs to perform option transfer can check the option trading data of the first terminal (option buyer) according to the second terminal, so that corresponding option information to be transferred can be determined according to the option trading data, and an option selling price can be set by an option seller according to the option purchase price set by the option buyer.
And S104, identifying the candidate option matched with the option trading data from at least one candidate option as a target option, and transferring the target option to the first terminal.
Here, transferring the target option to the first terminal may refer to changing the terminal to which the target option belongs to the first terminal. The target option is a candidate option of the at least one candidate option that matches the option trading data. For example, when the option trading data includes the value a1 of the electronic resource for acquiring the option pre-expenditure of the unit number and the number b1 of the options to be acquired, the target option may be a candidate option for which the value a2 of the electronic resource for acquiring the option pre-expenditure of the unit number is smaller than or equal to the value a1 of the electronic resource for acquiring the option pre-expenditure of the unit number and the number b1 of the options to be acquired is smaller than or equal to the number b2 of any one of the candidate options.
For example, describing the target option acquisition, the option trading data includes that the number of electronic resources required to be paid for the option of the unit number is 12, the number of options required to be acquired is 10, the number of electronic resources required to be paid for the 3 candidate options of the transfer unit number is 12, 13 and 14 respectively, and the number of electronic resources required to be paid for the candidate option c1, the candidate option c2 and the candidate option c3 is 10, 20 and 30 respectively, then the candidate option c1 is taken as the target option, and the candidate option c1 is transferred to the first terminal.
In one possible case, if the value a2 of the electronic resource required to be paid out for transferring the option of the unit number is smaller than or equal to the value a1 of the electronic resource required to be paid out for acquiring the option of the unit number, and the number b1 of the options required to be acquired is greater than the number b2 of any one of the candidate options, the candidate option of the number b2 is taken as a first target option, and the candidate option of the number b1-b2 and the smallest a3 is determined from the remaining candidate options and taken as a second target option, wherein the target option comprises the first target option and the second target option.
For example, the option trading data includes a number of 12 elements of electronic resources that are pre-paid for acquiring a unit number, a number of options that need to be acquired is 10, 3 candidate options that are required to be paid for transferring the unit number, that is, the number of electronic resources that need to be paid for candidate option c1, candidate option c2, candidate option c3 is respectively 12 elements, 13 elements, and 14 elements, and the corresponding numbers of candidate option c1, candidate option c2, and candidate option c3 are respectively 5, 10, and 30, then candidate option c1 is used as a first target option, and 5 candidate options c2 are used as a second target option, then the target option includes 5 candidate options c1 and 5 candidate options c2, and the 5 candidate options c1 and c2 are transferred to the first terminal. Optionally, the target option may only include the first target option, that is, only the 5 candidate options c1 are transferred to the first terminal, and the indication information for prompting that the current electronic resource of the first terminal is insufficient to obtain b1 is output, so as to prompt the first terminal to select other candidate options for subsequent purchase and other operations.
In the embodiment of the application, option trading data are acquired, wherein the option trading data are used for acquiring options from a blockchain by a first terminal; the option trading data may include, for example, the number of options that need to be acquired and the electronic resources that need to be paid for acquiring a unit number of options. Verifying the legitimacy of the first terminal according to option transaction data; whether the first terminal has validity can be determined by verifying whether the number of options to be acquired meets the rule or not and whether the electronic resource to be paid for acquiring the number of options of the unit meets the rule or not. If the first terminal has validity, reading at least one candidate option for trading from the blockchain; and identifying a candidate option matched with the option trading data from the at least one candidate option as a target option, and transferring the target option to the first terminal. For the first terminal, only the option trading data of the first terminal is uploaded to obtain the target option matched with the option trading data, and the first terminal is not required to select which candidate options to purchase, so that the option trading step can be simplified, and the option trading efficiency is improved; by uploading option trading data into the blockchain, illegal users can be prevented from tampering with the option trading, the authenticity of the trading can be ensured, and the safety of the option trading can be improved; and, because the blockchain has transparent characteristic, the option trading double can inquire the trade, so the fairness of the option trade can be ensured.
In one embodiment, the step S104 includes the following steps S11 to S14.
And s11, acquiring a terminal to which the target option belongs as a second terminal.
Here, the second terminal may be a terminal held by a user who transfers (i.e., sells) the target option.
And s12, reading the transfer condition of the target option from the blockchain.
Here, the transfer condition includes a first value of an electronic resource that needs to be paid out to transfer the target option. The first value is a value of an electronic resource required to be paid for transferring the target option equal to the number of options in the option trading data, that is, the first value is a product of the value of the electronic resource required to be pointed out for transferring the target option of the unit number and the number of options in the option trading data. The first value of the electronic resource that is required to be paid out to transfer the target option refers to the amount of funds that were purchased for the target option.
And s13, transferring the electronic resource with the first value from the first terminal to the second terminal.
Here, the electronic resource means funds for purchasing the target option, which may include at least a legal banknote, an electronic banknote, and the like; the legal currency refers to currency which is given by law to be used for forced circulation, such as RMB, dollars and the like; the electronic money is money stored in an electronic form in an electronic purse held by the user. The first value is a value of an electronic resource required to be paid by the first terminal to acquire the target option. The first value may be a specific value, for example, a natural number greater than zero, which is not limited in the embodiments of the present application. Transferring the electronic resource of the first value from the first terminal to the second terminal is: and transferring the electronic resource with the first value from the account corresponding to the first terminal to the account corresponding to the second terminal. After the first terminal transfers the electronic resource with the first value to the second terminal, the value of the electronic resource in the account corresponding to the first terminal is reduced by the first value, and the value of the electronic resource in the account corresponding to the second terminal is increased by the first value.
And s14, recording the attribution change information of the target option in the blockchain, wherein the attribution change information is used for indicating the attribution change of the target option to be the first terminal.
In steps s11 to s14, the second terminal may upload the target option and the transfer information of the target option to the blockchain in advance, where the transfer information of the target option includes the transfer condition of the target option, the number of target options and the terminal to which the target option belongs; the computer device may obtain a terminal to which the target option belongs, that is, the second terminal, from the blockchain, read a transfer condition of the target option, that is, a first value of an electronic resource required to be paid for transferring the target option, transfer the electronic resource of the first value from the first terminal to the second terminal, and record in the blockchain that the home terminal of the target option is changed to the first terminal. The electronic resource of the first numerical value is transferred to the second terminal, so that the transaction of the target option can be realized, and the user holding the first terminal, the user holding the second terminal and the management user of the institution where the first terminal is located can check the attribution information of the target option by recording the attribution change information of the target option in the blockchain, thereby being convenient for the management of the target option.
In one embodiment, the method may further comprise the following steps s21 to s22.
And s21, receiving a verification result of the option to be uploaded, which is sent by the data server aiming at the second terminal.
And s22, if the verification result indicates that the option to be uploaded passes the verification, determining the option to be uploaded as a candidate option, and determining that the option to be uploaded has validity according to the first attribute information of the option to be uploaded by the verification pass indication data server.
The first attribute information of the option to be uploaded may include a second value of the electronic resource to be paid for the option to be uploaded, which is obtained by the unit number, the first number of the option to be uploaded, and a terminal to which the option to be uploaded belongs. If the option to be uploaded has validity, the method can indicate that the second value of the electronic resource required to be paid out for obtaining the unit number of the option to be uploaded is smaller than or equal to a value threshold, the first number of the option to be uploaded is smaller than or equal to a value threshold, the terminal to which the option to be uploaded belongs is a second terminal, and the value threshold is the total number of options belonging to the second terminal.
In steps s21 to s22, before the second terminal uploads the option to be transferred to the blockchain, the data server may verify the option information corresponding to the option to be transferred uploaded by the second terminal. For example, it may be verified whether the second value of the electronic resource to be paid for obtaining the unit number of options to be uploaded is less than or equal to the value threshold, whether the first number of options to be uploaded is less than or equal to the value threshold, and whether the terminal to which the options to be uploaded belong is the second terminal. And when the second value of the electronic resource required to be paid out of the unit number of options to be uploaded is smaller than or equal to a value threshold, the first number of options to be uploaded is smaller than or equal to a value threshold, and the terminal to which the options to be uploaded belong is a second terminal, the data server sends a verification result of the options to be uploaded sent by aiming at the second terminal, and the computer equipment indicates that the options to be uploaded have legality when receiving the verification result indicating that the options to be uploaded pass verification. The data server may be, for example, a background server corresponding to the second terminal. The value threshold may be a specific value, for example, a value corresponding to an option number which is greater than zero and meets the unit number specified by the option trade, for example, a value corresponding to an option number specified by the option trade is 30, and the value threshold may be any value in the (0, 30) interval.
In one possible implementation manner, the data server may verify option information corresponding to the option to be transferred, which is uploaded by the second terminal, includes: verifying whether the second value of the electronic resource required to be paid out for obtaining the unit number of options to be uploaded is smaller than or equal to a value threshold, whether the first number of options to be uploaded is smaller than or equal to a value threshold, and whether the terminal to which the options to be uploaded belong is one or more of the second terminals. And considering that the option to be uploaded has validity under the condition that the second value of the electronic resource required to be paid out for acquiring the unit number of the option to be uploaded is smaller than or equal to a value threshold, the first number of the option to be uploaded is smaller than or equal to a value threshold, and the terminal to which the option to be uploaded belongs is one or more of the second terminals.
For example, a second value of the electronic resource required to be paid out for the option to be uploaded in a unit number is acquired to be smaller than or equal to a value threshold; or the first number of options to be uploaded is less than or equal to the number threshold; or the terminal to which the option to be uploaded belongs is a second terminal; or, acquiring a second value of the electronic resources to be paid out of the unit number of options to be uploaded to be smaller than or equal to a value threshold, and acquiring a first number of options to be uploaded to be smaller than or equal to the value threshold; or the first number of options to be uploaded is smaller than or equal to the number threshold value, and the terminal to which the options to be uploaded belong is a second terminal; or if the second value of the electronic resource required to be paid out of the unit number of options to be uploaded is smaller than or equal to the value threshold and the terminal to which the options to be uploaded belong is the second terminal, the options to be uploaded are considered to be legal.
In the embodiment of the application, for the option seller, namely the user holding the second terminal, since the buyer in the option trading mode, namely the user holding the first terminal, may be the company management user or other staff of the company, the problem that the benefit of the option seller is damaged due to low price recovery of the option when the option buyer is only the company management user can be avoided, the benefit of the option seller can be maintained, and the openness and fairness of the trade are ensured; moreover, as the option candidates, that is, the options to be uploaded, can be the options of the employees belonging to the mechanism, the option trading freedom among the employees can be realized, and the liquidity of the option trading is improved.
In one embodiment, the blockchain node system may perform the second verification on the option to be uploaded, and the specific method of the second verification may include the following steps s31 to s33.
And s31, obtaining second attribute information of the option to be uploaded from the data server.
And s32, verifying the validity of the option to be uploaded according to the second attribute information of the option to be uploaded.
And s33, if the option to be uploaded has validity, determining the option to be uploaded which passes the verification as at least one candidate option.
In one possible implementation manner, the second attribute information may be the same as the first attribute information, that is, the second attribute information may include obtaining a second value of the electronic resource to be paid for the unit number of options to be uploaded, the first number of options to be uploaded, and a terminal to which the options to be uploaded belong. Correspondingly, verifying the validity of the option to be uploaded according to the second attribute information of the option to be uploaded comprises: the method comprises the steps of obtaining one or more of a second value of electronic resources to be paid for of a unit number of options to be uploaded is smaller than or equal to a value threshold, a first number of options to be uploaded is smaller than or equal to a value threshold, a terminal to which the options to be uploaded belong is a second terminal, and the value threshold is one or more of the total number of options belonging to the second terminal, so that the options to be uploaded are determined to have legality. The accuracy of option verification can be improved by verifying the option to be uploaded through the data server and secondarily verifying the option to be uploaded through the block chain node system.
In another possible implementation, the second attribute information may be different from the first attribute information, e.g., the second attribute information includes a first number of options to be uploaded. Correspondingly, verifying the validity of the option to be uploaded according to the second attribute information of the option to be uploaded comprises: and if the sum of the first quantity and the second quantity of the options to be uploaded is smaller than or equal to the total number of the options, determining that the options to be uploaded have validity. Specifically, the total number of options belonging to the institution to which the second terminal belongs and the second number of options belonging to the third terminal can be obtained, and the third terminal and the second terminal belong to different terminals of the same institution; and if the sum of the first quantity and the second quantity of the options to be uploaded is smaller than or equal to the total number of the options, determining that the options to be uploaded have validity. Because the data server and the blockchain node system verify options to be uploaded from different dimensions, the options verification can be more comprehensive, and the accuracy of the options verification is improved.
If the option is an option transfer in a certain institution, for example, a stock transfer in the institution, the first terminal, the second terminal and the third terminal are terminals in the institution, that is, the user holding the first terminal and the user holding the second terminal and the user holding the third terminal are different employees of the same institution, and the option trade is an option trade performed between employees in the institution. The total number of options belonging to the institution to which the second terminal belongs is the total number of options of the institution, i.e. the sum of the number of options belonging to the second terminal and the number of options belonging to the third terminal. The third terminal belongs to an organization to which the second terminal belongs and is different from the second terminal, and it is known that the number of the third terminals may be one or more. The second number of options belonging to the third terminal includes a sum of the number of options belonging to the third terminal and requiring transfer and the number of options belonging to the third terminal and not requiring transfer.
If the sum of the first number and the second number of options to be uploaded is smaller than or equal to the total number of options, the first number of options to be uploaded, which indicates that the first number of options to be uploaded by the second terminal, has authenticity, the step of determining the authenticated options to be uploaded as at least one candidate option is executed. The first number of options to be uploaded has authenticity, which means that the data server is not tampered, and the first number of options to be uploaded by the second terminal is the number of options actually belonging to the second terminal. That is, there may be a manipulation of the data server such that the number of options actually belonging to the second terminal is smaller or larger than the number of options actually belonging to the second terminal after the manipulation. For example, if the number of options actually belonging to the second terminal is 20, and the number of options actually belonging to the second terminal after tampering is 30, but the number of options actually belonging to the second terminal is only 20, the first number of options to be uploaded by the second terminal is considered to be unrealistic.
In the embodiment of the application, the option to be uploaded is verified through the data server, so that the option to be uploaded accords with the sales rule (for example, the price of the sales option, the quantity of the sales option, the terminal to which the sales option belongs and the transferable state of the sales option accord with the rule), and the option to be uploaded is verified for the second time through the block link point system, so that illegal users can be prevented from tampering with the option of the second terminal, the accuracy of the option verification is improved, and the authenticity of the option to be uploaded of the second terminal is ensured.
In the above embodiment, the method for verifying the option to be uploaded sent by the data server for the second terminal and sending the verification result to the blockchain node system for performing the second verification may refer to fig. 6, and fig. 6 is a schematic flow diagram of a blockchain-based data processing method provided in the embodiment of the present application, where the method is applied to a node in a blockchain network, and the node may refer to a computer device; as shown in fig. 6, the data processing method may include the steps of: s201 to S204.
S201, the second terminal sends options to be uploaded to the data server.
S202, the data server verifies the option to be uploaded.
And S203, if the verification result indicates that the option to be uploaded passes the verification, the option to be uploaded and the verification result aiming at the option to be uploaded are sent to the block link point system.
And S204, after the block chain node system passes the secondary verification of the option to be uploaded, determining the option to be uploaded as a candidate option.
Here, the method for verifying the option to be uploaded by the data server may refer to the methods of steps s21 to s22, and the method for secondarily verifying the option to be uploaded by the blockchain node system may refer to the methods of steps s31 to s33, which are not described herein.
In the embodiment of the application, the option to be uploaded is verified through the data server, so that the option uploaded by the second terminal accords with the selling rule, when the data server verifies that the option to be uploaded passes, the option to be uploaded and the verification result are sent to the block chain link point system, the block chain link point system performs secondary verification on the option to be uploaded, after the secondary verification passes, the option to be uploaded is determined to be a candidate option, and the candidate option matched with the option trading data is conveniently identified according to the option trading data of the first terminal, so that the first terminal purchases the candidate option.
In one embodiment, the step S104 includes the following steps S41 to S44.
s41, reading the trading state of at least one candidate option from the blockchain.
And s42, screening the candidate options with the trading state in the non-locking state from at least one candidate option as the option to be selected.
And s43, identifying the option to be selected matched with the option trading data from the options to be selected as a target option.
In steps s41 to s43, the trading states of the candidate options include a locked state and an unlocked state, and the trading states of the candidate options are the locked state for indicating: the first terminal may not acquire the candidate option if a terminal other than the first terminal is currently required to acquire the candidate option and the terminal is in a state of waiting to transfer or is transferring electronic resources to the second terminal. The trading state of the candidate option is an unlocked state for indicating: and if the terminal except the first terminal does not need to acquire the candidate option currently, the first terminal can acquire the candidate option. Optionally, the locking state may be a time length for locking the candidate option, where the time length meets a time length threshold, and if the current time length reaches the time length threshold, the terminal except the first terminal does not complete to acquire the candidate option, the locking state of the candidate option is changed to an unlocking state, so that the first terminal or the subsequent other terminals can acquire the candidate option conveniently.
The computer equipment reads the trading state of at least one candidate option from the blockchain, screens the candidate option with the trading state in the unlocking state from the at least one candidate option, and identifies the option to be selected matched with option trading data from the option to be selected as a target option. That is, the computer device reads whether the trading state of at least one candidate option is a locked state from the blockchain, and identifies a candidate option matching the option trading data from among the non-locked state candidates as a target option, thereby realizing option trading.
In this embodiment, the option trading data includes a third value of the electronic resource for acquiring the unit number of option pre-payouts, and the step s43 includes the following steps s51 to s53.
s51, reading a transfer condition of the option to be selected from the blockchain, wherein the transfer condition comprises a fourth value of electronic resources required to be paid out for transferring the option of the unit number.
And s52, selecting the option to be selected with the minimum corresponding fourth value from the options to be selected as the first option to be selected.
And s53, if the third value is greater than the fourth value corresponding to the first option, determining the first option as the target option.
In steps s51 to s53, the computer device reads the transfer condition of the option to be selected from the blockchain, that is, reads the fourth value of the electronic resource required to be paid by transferring the number of options of the unit, and screens out the option to be selected with the minimum corresponding fourth value from the options to be selected, and if the third value is greater than the fourth value corresponding to the first option, the computer device determines the first option to be the target option.
For example, the process of steps s51 to s53 is described, where, for example, the option trading data includes a third value of an electronic resource that is pre-paid for acquiring a unit number of options, the third value is 12.8 yuan, the 3 options to be selected are option d1, option d2, option d3, and a fourth value of an electronic resource that is required to be paid for transferring a unit number of options corresponding to option d1, option d2, option d3 is 12.5 yuan, 13 yuan, and 13.5 yuan, respectively, and then the first option is to screen out an option to be selected with the smallest corresponding fourth value from the 3 options to be selected, that is, the option d1 is selected, and the third value is greater than 12.5, and then the option d1 is determined as the target option. And determining the option to be matched with the option trading data by comparing the size relation between the third value of the electronic resource of the option pre-expenditure of the unit number and the fourth value of the electronic resource required to be expended for transferring the option of the unit number in the transfer condition of the option to be selected, thereby realizing the option data trading.
In one embodiment, the method may further comprise the following steps s61 to s63.
s61, a target block is established in the blockchain.
s62, generating a suspension transfer instruction message of the target block, where the suspension transfer instruction message is used to instruct suspension transfer of the target option before receiving the uploading request of the first terminal for the target option.
s63, record the pause transition instruction information into the target block.
In steps s61 to s63, in the case where the option trade is completed, that is, in the case where the first terminal obtains the target option, the computer device transfers the electronic resource of the first value from the first terminal to the second terminal, and after recording the change of the attribution of the target option to the first terminal in the blockchain, the computer device establishes a target block in the blockchain, where the target block may include information of the target option, for example, may include terminal information of the target option, the attribution change time of the target option, and the first value of the electronic resource paid by obtaining the target option, and so on. The computer device may cause the target option to be suspended for transfer before receiving the upload request of the first terminal for the target option by generating the suspension transfer instruction information of the target block, and record the suspension transfer instruction information in the target block. That is, after the pause transfer instruction information of the target block is generated and before the first terminal receives the upload request for the target option, the pause transfer of the target option is performed, that is, the terminal to which the target option belongs does not change any more in the time period.
In a possible implementation manner, as shown in fig. 4, for example, the target option is option 1, after the first terminal acquires the target option, canceling the acquired target option of the first terminal displayed in the display interface, the display interface may be as shown in fig. 7a, and fig. 7 is a schematic view of a display interface to be transferred for an option provided in an embodiment of the present application; or if the number of the target options acquired by the first terminal is smaller than the number of the options 1 displayed in the display interface, changing the number of the options 1 in the display interface to the difference between the number of the options 1 displayed in the display interface and the number of the target options acquired by the first terminal. For example, if the number of target options acquired by the first terminal is 12.4K and the number of options 1 in the display interface is 13.4K, the number of options 1 in the changed display interface is 13.4K-12.4k=1k, and the display interface may be as shown in fig. 7 b.
By establishing the target block in the block chain after the option trade is completed, the suspension transfer indication information of the target block is generated, thereby avoiding the option trade confusion caused by the repeated acquisition of the target option by other terminals and improving the efficiency of the option trade.
In one embodiment, the option trading data includes a third number of options acquired by the first terminal, and the step S102 includes the following steps S71-S72.
And S71, acquiring the number of transfer options, wherein the number of transfer options belongs to a mechanism corresponding to the second terminal and is in a state to be transferred.
And s72, if the third quantity is smaller than the transfer option quantity, determining that the first terminal has validity.
In steps s71 to s72, the computer device determines whether the first terminal has validity by acquiring the number of transfer options belonging to the mechanism corresponding to the second terminal and in the state to be transferred, and by verifying whether the third number of options acquired by the first terminal in the option trading data is smaller than the number of transfer options. If the third number of options acquired by the first terminal is smaller than the number of transfer options which belong to the mechanism corresponding to the second terminal and are in the state to be transferred, determining that the first terminal has validity. If the third number of options acquired by the first terminal is greater than the number of transfer options which belong to the mechanism corresponding to the second terminal and are in the state to be transferred, determining that the first terminal has no validity. It can be known that if the third number of options acquired by the first terminal is equal to the number of transfer options belonging to the mechanism corresponding to the second terminal and in the state to be transferred, determining that the first terminal has validity. That is, the computer device determines whether the first terminal has validity by first acquiring the number of options that the mechanism corresponding to the second terminal currently needs to transfer, and comparing the size between the number of options that the first terminal needs to acquire and the number of options that the mechanism needs to transfer. Optionally, it may also be determined whether the time in the option trade data coincides with the current time of the computer device, etc., thereby determining that the first terminal has validity.
Optionally, before the blockchain node system obtains option trading data, the data server may verify the option trading data, to verify whether the terminal to which the option obtained by the first terminal belongs is a second terminal, whether the option obtained by the first terminal is a saleable option, for example, whether the option is a non-saleable option specified by the institution, and so on; and the first terminal acquires whether the value of the electronic resource required to be paid out of the option of the unit number is larger than or equal to the second value of the electronic resource required to be paid out of the option to be uploaded of the unit number in the option to be uploaded information uploaded by the second terminal. The option purchased by the second terminal can be enabled to meet the specification by verifying the option purchased by the first terminal through the data server, for example, the terminal to which the option purchased by the first terminal belongs is legal, the purchased option is a saleable option, the electronic resource for purchasing the option by the first terminal is enough, and the like. The option trading data of the first terminal is secondarily verified through the blockchain node system, so that the validity of the option trading data of the first terminal and the accuracy of the option trading can be improved.
