It should be noted that the option trading may also be executed by the first terminal or the second terminal, and the manner in which the first terminal and the second terminal perform the option trading may refer to the manner in which the blockchain node system performs the option trading, which is described below by taking the example of performing the option trading by using the blockchain node system as an example.

In addition, please refer to fig. 1b, fig. 1b is a schematic diagram of a block link point system according to an embodiment of the present disclosure. As shown in fig. 1b, a block-linked point system may include a plurality of nodes, each of which may receive input information during normal operation and maintain transaction information data in the block-linked point system based on the received input information. In order to ensure information intercommunication in the block link point system, information connection can exist between each node in the block link point system, and information transmission can be carried out between the nodes through the information connection. For example, when any node in the blockchain node system receives input information, other nodes in the blockchain node system acquire the input information according to a consensus algorithm, and store the input information as data in transaction information data, so that the data stored in all nodes in the blockchain node system are consistent.

Each node in the block chain node point system has a corresponding node identifier, and each node in the block chain node point system can store the node identifiers of other nodes in the block chain node point system, so that the generated block can be broadcast to other nodes in the block chain node point system according to the node identifiers of other nodes. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.

TABLE 1

Node name	Node identification
		Node
1	117.114.151.174
		Node 2	117.116.189.145
…	…
		Node N	119.123.789.258

Each node in the blockchain nodal system stores one identical blockchain. Referring to fig. 1c, fig. 1c is a schematic block chain diagram provided in an embodiment of the present application, as shown in fig. 1c, the block chain is composed of a plurality of blocks, a starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp, and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

The embodiment of the application utilizes the intelligent contract in the blockchain technology and the characteristic that the blockchain is not falsifiable to process option transaction data, namely, provides a data processing method based on the blockchain, wherein the intelligent contract, namely, a computerized protocol, can execute the terms of a certain contract, and is realized by a code which is deployed on a shared account and used for executing when a certain condition is met, and the intelligent contract is used for completing an automated transaction according to an actual business requirement code, and of course, the intelligent contract is not limited to executing the contract for transaction, but also can execute the contract for processing received information. The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission (P2P transmission), consensus mechanism, encryption algorithm and the like, and is essentially a decentralized database; the blockchain can be composed of a plurality of serial transaction records (also called blocks) which are connected in series by cryptography and protect the contents, and the distributed accounts connected in series by the blockchain can effectively record the transactions by multiple parties and can permanently check the transactions (can not be tampered). The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the block chain network; that is, the consensus mechanism is a mathematical algorithm commonly recognized by network nodes in the blockchain.

The nodes in the block link node system 10 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, Content Delivery Network (CDN), big data, and an artificial intelligence platform. The first terminal and the second terminal may be computer devices, including a mobile phone, a tablet computer, a notebook computer, a palm computer, an intelligent sound, a Mobile Internet Device (MID), a POS (Point Of Sales) device, a wearable device (e.g., a smart watch, a smart bracelet, etc.), and the like.

In practical application, the data processing system may be used in a scenario of trading options of various subject matters, as shown in fig. 1d, fig. 1d is a scenario diagram of an interaction process of each device in the data processing system provided in the embodiment of the present application, and assuming that a queen needs to purchase an option, a terminal corresponding to the queen may be referred to as a first terminal, and assuming that a duet sells the option, a terminal corresponding to the duet may be referred to as a second terminal. Before the little-wane sends the option transaction data to the block-linked point system, the user (e.g., a small plum) selling the option can upload the option to be sold, i.e., the option to be uploaded, to the block-linked point system through the second terminal, and the block-linked point system saves the option to be uploaded to obtain at least one candidate option. When the queen needs to acquire (purchase) an option, first, the queen may initiate option trading data for purchasing the option through an application that performs the option trading, and the option trading data may include a value of an electronic resource for acquiring a unit amount of option to be paid out, an amount of the option that needs to be acquired, and the like. Then, after acquiring the option trading data of the option for buying, the block link point system verifies the validity of the terminal of the queen according to the option trading data, for example, verifies whether the number of options to be bought by the queen meets the specification, for example, whether the number of options to be bought by the queen is greater than zero and less than the total number of options belonging to the mechanism of the queen, and whether the number of electronic resources to be paid out for acquiring the options of the unit number meets the specification, for example, whether the number of electronic resources to be paid out for acquiring the options of the unit number is greater than or equal to the average value of the electronic resources. If the terminal of the queen meets the legitimacy, for example, the number of options to be purchased by the queen and the electronic resources required to purchase the options in the unit number are both in compliance with the regulations, at least one candidate option for trading is read from the blockchain, where the candidate options include all options to be sold, for example, the options sold by the duel or the options sold by other staff of the institution where the queen is located, such as the staff of the yellow, the little tang, the little chen, etc. Then, a candidate option matching the option trading data is identified from the at least one candidate option, the target option is transferred to the terminal of the queen as a target option, and the electronic resource corresponding to the target option is transferred from the terminal of the queen to the terminal of the plum. In this way, the block link point system realizes the option trading by identifying the options matched with the option trading data of the first terminal, and because the option trading is directly conducted without an option transfer party and an option obtaining party, only the option information needing to be transferred needs to be uploaded for the option transfer party (seller), and only the option information needing to be obtained needs to be uploaded for the option obtaining party (buyer), the option trading can be realized, the steps of the option trading can be simplified, the efficiency of the option trading is improved, and the safety and the fairness of the option trading are improved.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a data processing method based on a blockchain according to an embodiment of the present application, where the method is applied to a node in a blockchain network, where the node may refer to a computer device; as shown in fig. 2, the data processing method may include the following steps S101 to S104.

And S101, acquiring option trading data.

Here, the option trade data is used for the first terminal to acquire an option from the block chain. The first terminal is a terminal held by a user who needs to acquire an option, and the object of the option is an asset selected for purchase or sale, including shares, stocks, government bonds, money, stock indexes, commodity futures, and the like. For example, the option of a stock of an organization may be traded, and the first terminal is the terminal held by the user who wants to acquire the option of the stock. The option trading data may include, for example, a value of an electronic resource to which a unit number of options is to be paid out, the number of options that need to be acquired, the time at which the options need to be acquired, and identity information of a user holding the first terminal, and the like. For example, the option in the embodiment of the present application may refer to one of an option corresponding to a stock of an organization, an option corresponding to a government bond of an organization, or an option of another object.

Optionally, when generating each block in the block chain, referring to fig. 3, fig. 3 is a schematic diagram of an option transaction information chaining process provided in an embodiment of the present application, where a node where the block chain is located verifies input information (option transaction data) when receiving the input information, and after completing the verification, stores the input information in a memory pool, and updates a hash tree used for recording the input information; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple 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 is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the block chain link point system where the newly generated blocks are located according to the node identifications of the other nodes in the block chain link point system, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks 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 the option trade data of the first terminal complies with the specification. For example, the value of the electronic resource to be paid out for acquiring the option of the unit number by the first terminal, the number of options to be acquired, and the like may be included to meet the specification. The validity of the first terminal can be verified according to the value of the electronic resource paid out in advance for acquiring the options of the unit quantity, the quantity of the options required to be acquired, and the like. For example, when the value of the electronic resource for acquiring the unit number of option payout is greater than or equal to the average value of the electronic resources for acquiring the unit number of option payout, it is determined that the first terminal has validity; or when the number of options required to be acquired is greater than zero and less than the total number of options belonging to the mechanism where the first terminal is located, determining that the first terminal has validity; or, when the value of the electronic resource for acquiring the unit number of option pre-payout is greater than or equal to the average value of the electronic resources for acquiring the unit number of option pre-payout, and 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, it is determined that the first terminal is legal, and so on.

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 transaction data may further include: acquiring the option quantity of a user corresponding to a 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 less than or equal to the upper threshold; if the first terminal is larger than the upper threshold, the first terminal is determined not to have validity, and the like.

S103, if the first terminal has validity, at least one candidate option for trading is read from the blockchain.

Here, if the first terminal has validity, reading at least one candidate option for trading from the blockchain; if the first terminal does not have the validity, a prompt message for prompting the first terminal to modify the option transaction data can be generated. For example, the hint information may include "option quantity is not eligible for trading", "option price is not eligible for trading", and the like, and the user holding the first terminal may modify the option trading data according to the hint information so that the modified option trading data is eligible for trading, 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 option information to be transferred uploaded by the second terminal, which performs option transfer according to needs, in the option trading application by the computer device, for example, the option information to be transferred may include a value of an electronic resource to be paid out to acquire a unit quantity of options, a quantity of options to be sold, a time of options to be sold, and the like. And the block chain node system stores the option information to be transferred uploaded by the second terminal to obtain candidate options. It can be understood that the number of the second terminals may be multiple, that is, users corresponding to 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 an interface corresponding to the option trading application according to the option information to be transferred uploaded by each second terminal, as shown in fig. 4, fig. 4 is a schematic view of a display interface of options to be transferred provided in this embodiment of the present application, fig. 4 includes 7 options to be transferred, for example, the value of the electronic resource to be paid out by acquiring option 1 of a unit number is 12.960, the number of option 1 is 13.4K, and K is a metering unit; the value of the electronic resource to be paid out for acquiring option 2 in unit number is 12.980, and the number of options 2 is 1.429M, where M is also a measure, and M is greater than K. It is known that the same option to be transferred may include options to be transferred uploaded by the plurality of second terminals, and the values of the electronic resources that need to be paid out for obtaining the unit number of options to be transferred in the options to be transferred uploaded by the plurality of second terminals are equal. For example, the number of options 1 is 13.4K, which includes the total number of options uploaded by the 3 second terminals, and among the options uploaded by the 3 second terminals, the number of electronic resources that need to be paid out to obtain the unit number of options is 12.960.

In a possible implementation manner, for example, when there is no option transferred by the second terminal or all options of the period to be transferred of the second terminal are transferred, the first terminal needs to acquire the option, and option trading data of the first terminal may be displayed on an 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 multiple, option trading data of multiple first terminals is presented, as shown in fig. 5, fig. 5 is a schematic view of a presentation interface of option trading data provided in an embodiment of the present application, fig. 5 includes option trading data of multiple first terminals, for example, option trading data of first terminal 1 includes that the value of the electronic resource pre-paid by acquiring unit number of option 1 is 12.940, and the number of option 1 is 639.8K, and so on. By presenting the option transaction data of the first terminal, the user (option seller) who needs to perform option transfer can check the option transaction data of the first terminal (option purchaser) according to the second terminal, so that the corresponding option information to be transferred can be determined according to the option transaction data, that is, the option seller can set the option selling price according to the option purchasing price set by the option purchaser.

And S104, identifying candidate options matched with the option trading data from at least one candidate option, taking the candidate options as target options, and transferring the target options 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 that matches the option trade data among the at least one candidate option. For example, when the option trading data includes the value a1 of the electronic resource to be paid out for acquiring the unit number of options and the number b1 of the options to be acquired, the target option may be a candidate option in which the value a2 of the electronic resource to be paid out for transferring the unit number of options is less than or equal to the value a1 of the electronic resource to be paid out for acquiring the unit number of options, and the number b1 of the options to be acquired is less than or equal to the number b2 of any one candidate option.

For example, the acquisition of the target option is described, for example, the option trading data includes that the value of the electronic resource to be paid out for acquiring the unit number of options is 12 yuan, the number of the options to be acquired is 10, the values of the electronic resources to be paid out for transferring the unit number of 3 kinds of candidate options, that is, the candidate option c1, the candidate option c2, and the candidate option c3 are 12 yuan, 13 yuan, and 14 yuan, respectively, and the corresponding numbers of the candidate option c1, the candidate option c2, and the candidate option c3 are 10, 20, and 30, respectively, 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 unit number of options is less than or equal to the value a1 of the electronic resource required to be paid out for acquiring the unit number of options, and the number b1 of the options required to be acquired is greater than the number b2 of any one candidate option, the candidate option with the number b2 is used as the first target option, and the candidate options with the numbers b1 to b2 and the smallest a3 are determined from the remaining candidate options, and are used as the second target option, and the target options include the first target option and the second target option.

For example, the option trading data includes that the value of the electronic resource required to pay out the option in the unit number is 12, the number of the options required to be acquired is 10, the values of the electronic resources required to pay out the unit number of the 3 candidate options, that is, the candidate option c1, the candidate option c2, and the candidate option c3 are 12, 13, and 14, respectively, and the corresponding numbers of the candidate option c1, the candidate option c2, and the candidate option c3 are 5, 10, and 30, respectively, then the candidate option c1 is used as the first target option, and the 5 candidate option c2 is used as the second target option, the target option includes 5 candidate options c1 and 5 candidate options c2, and the 5 candidate options c1 and 5 candidate options c2 are transferred to the first terminal. Alternatively, the target option may only include the first target option, that is, only 5 candidate options c1 are transferred to the first terminal, and indication information for prompting the first terminal that the current electronic resource is not enough to acquire b1 is output to prompt the first terminal to select other candidate options for subsequent purchase, and so on.

In the embodiment of the application, option trading data is acquired, and the option trading data is used for acquiring an option from a blockchain by a first terminal; option transaction data may include, for example, the number of options to be acquired and the electronic resources to be paid for acquiring a unit number of options. Verifying the validity of the first terminal according to the option transaction data; whether the first terminal is legitimate may be determined by verifying whether the number of options required to be acquired meets a specification and whether the electronic resource to be paid for acquiring a unit number of options meets a specification. If the first terminal has validity, reading at least one candidate option for trading from the blockchain; candidate options matching the option trade data are identified from the at least one candidate option as target options, and the target options are transferred to the first terminal. For the first terminal, the target option matched with the option trading data can be obtained only by uploading the option trading data of the first terminal, and the option trading steps can be simplified without selecting which candidate options to buy by the first terminal, so that the option trading efficiency is improved; by uploading option transaction data to the block chain, the option transaction can be prevented from being tampered by an illegal user, the authenticity of the transaction can be ensured, and the safety of the option transaction can be improved; and, because the blockchain has the transparent characteristic, the option trading parties can inquire the trading, so that the fairness of the option trading can be ensured.

In one embodiment, the step S104 includes the following steps S11-S14.

s11, the terminal to which the target option belongs is acquired as the second terminal.

Here, the second terminal may be a terminal held by the user who transfers (i.e., sells) the target option.

s12, reading the branch 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 the value of the electronic resource required to be paid out for transferring the target option equal to the number of options in the option trading data, that is, the first value is the product of the value of the electronic resource required to be indicated for transferring the unit number of the target option and the number of options in the option trading data. The first value of the electronic resource to be expended to transfer the target option refers to the amount of funds to purchase the target option.

s13, transferring the first value of the electronic resource from the first terminal to the second terminal.

Here, the electronic resource means a fund for purchasing a target option, which may include at least a french coin, electronic money, and the like; the legal currency is a currency which is given to the legal currency for forced circulation, such as RMB, USD and the like; electronic money is money that is stored in electronic form in an electronic wallet held by a user. The first value is a value of electronic resources required to be paid out by the first terminal to obtain the target option. The first value may be a specific value, for example, a natural number greater than zero, which is not limited in this embodiment. Transferring the first value of the electronic resource from the first terminal to the second terminal: and transferring the electronic resource with the first numerical value from the account corresponding to the first terminal to the account corresponding to the second terminal. Therefore, 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 decreased 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.

s14, change information of attribution of the target option is recorded in the blockchain, and the change information of attribution is used to instruct the change of attribution of the target option to the first terminal.

In steps s 11-s 14, 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 the target options, and the terminal to which the target option belongs; the computer device may acquire the terminal to which the target option belongs, i.e., the second terminal, from the blockchain, read the transfer condition of the target option, i.e., the first value of the electronic resource that needs to be paid out to transfer the target option, transfer the electronic resource of the first value from the first terminal to the second terminal, and change the terminal to which the target option belongs to the blockchain into the first terminal. The electronic resource with the first value is transferred to the second terminal, the transaction of the target option can be realized, and the ownership change information of the target option is recorded in the blockchain, so that the ownership information of the target option can be checked by a user holding the first terminal, a user holding the second terminal and a management user of an organization where the first terminal is located, and the management of the target option is facilitated.

In one embodiment, the method may further include the following steps s 21-s 22.

And s21, receiving the verification result of the option to be uploaded sent by the data server to the second terminal.

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 the verification passing is used for indicating the data server to determine that the option to be uploaded has validity according to the first attribute information of the option to be uploaded.

The first attribute information of the option to be uploaded may include a second value of the electronic resource to be paid out for acquiring a unit number of the option to be uploaded, a 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, it may be indicated that the second number of the electronic resources that need to be paid out to acquire the unit number of the option to be uploaded is less than or equal to the number threshold, the first number of the option to be uploaded is less than or equal to the number threshold, and the terminal to which the option to be uploaded belongs is the second terminal, where the number threshold is the total number of the options belonging to the second terminal.

In steps s 21-s 22, before the option to be transferred is uploaded to the blockchain by the second terminal, 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 out for acquiring the unit number of options to be uploaded is less than or equal to a value threshold, whether the first number of options to be uploaded is less than or equal to a number threshold, and whether the terminal to which the options to be uploaded belong is the second terminal. And under the condition that the second value of the electronic resources required to be paid out for acquiring the unit number of the options to be uploaded is smaller than or equal to the value threshold, the first number of the options to be uploaded is smaller than or equal to the number threshold, and the terminal to which the options to be uploaded belong is the second terminal, the data server sends a verification result aiming at the options to be uploaded sent by the second terminal, and when the computer equipment receives the verification result indicating that the options to be uploaded pass the verification, the computer equipment indicates that the options to be uploaded have validity. 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 greater than zero and corresponding to the unit number of options specified in the option deal, for example, if the value corresponding to the unit number of options specified in the option deal is 30, the value threshold may be any one of values in the interval (0, 30).

In a possible implementation manner, the manner in which the data server can verify the option information corresponding to the option to be transferred and uploaded by the second terminal includes: and verifying whether the second value of the electronic resource required to be paid out by acquiring the unit number of the options to be uploaded is less than or equal to a value threshold, whether the first number of the options to be uploaded is less than or equal to a number threshold, and whether the terminal to which the options to be uploaded belong is one or more of a second terminal. 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 options to be uploaded is less than or equal to the value threshold, the first number of the options to be uploaded is less than or equal to the number threshold, and the terminal to which the option to be uploaded belongs is one or more of the second terminals.

For example, the second value of the unit quantity of electronic resources to be paid out for the option to be uploaded is acquired to be less than or equal to the 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, the second number of the electronic resources which need to be paid out for obtaining the unit number of options to be uploaded is smaller than or equal to the number threshold, and the first number of the options to be uploaded is smaller than or equal to the number threshold; or the first number of options to be uploaded is less than or equal to the number threshold, and the terminal to which the option to be uploaded belongs is the second terminal; or, when the second value of the electronic resource to be paid out for the unit number of options to be uploaded is less than or equal to the value threshold and the terminal to which the option to be uploaded belongs is the second terminal, the option to be uploaded is considered to be legal.

In the embodiment of the application, for the option seller, that is, the user holding the second terminal, since the buyer in the option trading mode, that is, the user holding the first terminal may be a company management user or may be other employees of the company, it is possible to avoid that the benefit of the option seller is damaged due to low-price option recovery when the option buyer is only a company management user, and it is possible to maintain the benefit of the option seller and ensure the openness and fairness of the trading; in addition, because the candidate options, namely the options to be uploaded can be the options of the staff belonging to the institution, the option trading freedom among the staff can be realized, and the liquidity of the option trading is improved.

In one embodiment, the block link point system may perform secondary verification on the option to be uploaded, and the method of secondary verification may include the following steps s 31-s 33.

s31, obtaining the 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 verified option to be uploaded as at least one candidate option.

In a possible implementation manner, the second attribute information may be the same as the first attribute information, that is, the second attribute information may include a second value of the electronic resource to be paid out to acquire a unit number of options to be uploaded, a 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 a unit number of electronic resources which need to be paid out for options to be uploaded and have a second value smaller than or equal to a numerical threshold, obtaining a unit number of electronic resources which need to be paid out for options to be uploaded and have a first number smaller than or equal to a number threshold, and obtaining a terminal to which the options to be uploaded belong as a second terminal, wherein the number threshold is one or more of the total number of options belonging to the second terminal, and therefore the options to be uploaded are determined to be legal. The accuracy of option verification can be improved by verifying the option to be uploaded through the data server and verifying the option to be uploaded for the second time through the block link point system.

In another possible implementation manner, the second attribute information may be different from the first attribute information, for example, the second attribute information includes the 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 number and the second number of the options to be uploaded is less 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 may 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 number and the second number of the options to be uploaded is less than or equal to the total number of the options, determining that the options to be uploaded have validity. The option to be uploaded is verified from different dimensions by the data server and the block link point system, so that the option verification is more comprehensive, and the accuracy of the option verification is improved.

If the option is an option transfer within a certain organization, for example, a stock transfer of the organization, the first terminal, the second terminal, and the third terminal are terminals within the organization, that is, the user holding the first terminal, the user holding the second terminal, and the user holding the third terminal are different employees of the same organization, and the option transaction is an option transaction performed between employees within the organization. The total number of options belonging to the institution to which the second terminal belongs is the total number of options of the institution, that is, the total number of options belonging to the second terminal and the number of options belonging to the third terminal. The third terminal belongs to the mechanism 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 requiring no transfer.

Here, if the sum of the first number and the second number of options to be uploaded is less than or equal to the total number of options, which indicates that the first number of options to be uploaded by the second terminal has authenticity, the step of determining the validated options to be uploaded as at least one candidate option is performed. The first number of options to be uploaded to be authentic 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 case where the data server is tampered such that the number of options actually belonging to the second terminal is smaller or larger than the number of options belonging to the second terminal after the tampering. For example, if the number of options actually belonging to the second terminal is 20, and the number of options belonging to the second terminal after falsification is 30, but the number of options belonging to the second terminal is only 20, it is considered that the first number of options to be uploaded by the second terminal is not authentic.

In the embodiment of the application, the option to be uploaded is verified through the data server, so that the option to be uploaded meets the selling regulations (for example, the price of the option to be sold, the number of the option to be sold, the terminal to which the option to be sold belongs, and the transferable state of the option to be sold all meet the regulations), and the option to be uploaded is verified secondarily through the block link node system, so that an illegal user can be prevented from tampering the option of the second terminal, the accuracy of 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 the data server to verify the option to be uploaded sent by the second terminal and send the verification result to the blockchain node system for secondary verification may refer to fig. 6, where fig. 6 is a schematic flow diagram of a data processing method based on a blockchain provided in this embodiment of the present application, 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 the option to be uploaded to the data server.

S202, the data server verifies the option to be uploaded.

S203, if the verification result indicates that the option to be uploaded passes the verification, sending the option to be uploaded and the verification result for the option to be uploaded to the block link point system.

And S204, after the block link point system passes the secondary verification of the option to be uploaded, determining the option to be uploaded as a candidate option.

Here, the manner of verifying the option to be uploaded by the data server may refer to the manner of steps s21 to s22, and the manner of verifying the option to be uploaded by the block link point system may refer to the manner of steps s31 to s33, which is not described herein again.

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 meets the selling regulations, when the option to be uploaded is verified to pass through by the data server, the option to be uploaded and the verification result are sent to the block chain node system, the block chain node system conducts secondary verification on the option to be uploaded, after the secondary verification is passed, the option to be uploaded is determined as a candidate option, the candidate option matched with the option transaction data is conveniently identified according to the option transaction data of the first terminal, and therefore the first terminal can purchase the candidate option.

In one embodiment, the step S104 includes the following steps S41-S44.

s41, reading the trade status of at least one candidate option from the blockchain.

s42, selecting the candidate option with the trade status in the non-locked status from the at least one candidate option as the option to be selected.

s43, identifying the option to be selected matching the option trade data from the options as the target option.

In steps s 41-s 43, the trading status of the candidate option includes a locked status and an unlocked status, and the trading status of the candidate option is a locked status for indicating: if there is a terminal other than the first terminal that needs to acquire the candidate option and the terminal is waiting to transfer or is transferring the electronic resource to the second terminal, the first terminal may not acquire the candidate option. The trading status of the candidate option is an unlocked status indicating: if no terminal other than the first terminal needs to acquire the candidate option, the first terminal may acquire the candidate option. Optionally, the lock state may be that a duration for locking the candidate option satisfies a duration threshold, and if the current duration reaches the duration threshold, and the terminal other than the first terminal does not finish obtaining the candidate option, the lock state of the candidate option is changed to a non-lock state, so that the first terminal or another subsequent terminal can obtain the candidate option conveniently.

The computer device reads the trading state of at least one candidate option from the blockchain, screens out candidate options with the trading state in a non-locked state from the at least one candidate option as candidate options, and identifies the candidate options matched with the option trading data from the candidate options as target options. That is, the computer device reads from the block chain whether the trading state of at least one candidate option is a locked state, and identifies an option to be selected that matches the option trading data from among options in non-locked states as a target option, thereby implementing option trading.

In this embodiment, the option trading data includes a third value of the electronic resource for acquiring the unit amount of option pre-payout, and the step s43 includes the following steps s 51-s 53.

s51, reading the transfer condition of the option to be selected from the blockchain, wherein the transfer condition comprises a fourth value of the electronic resource required to be paid out for transferring the option with unit number.

And s52, selecting the option to be selected with the smallest fourth value from the options to be selected as the first option to be selected.

s53, if the third value is greater than the fourth value corresponding to the first option to be selected, then the first option to be selected is determined as the target option.

In steps s51 to s53, the computer device selects the option to be selected that corresponds to the smallest fourth value from the options to be selected as the first option by reading the transfer condition of the option to be selected, that is, reading the fourth value of the electronic resource that needs to be paid out to transfer the unit number of options from the blockchain, and determines the first option to be selected as the target option if the third value is greater than the fourth value corresponding to the first option.

For example, the process of the above steps s51 to s53 is described, for example, the option trading data includes that the third value of the electronic resource to be paid out in advance for acquiring the option in unit quantity is 12.8 yuan, the fourth values of the electronic resource to be paid out for transferring the option in unit quantity corresponding to the 3 options are 12.5 yuan, 13 yuan and 13.5 yuan, respectively, the option d1, the option d2 and the option d3 are 12.5 yuan, 13 yuan and 13.5 yuan, respectively, the first option is to select the option with the smallest fourth value from the 3 options, that is, the option d1, and the third value 12.8 is greater than 12.5, and then the option d1 is determined as the target option. And determining the option to be selected matched with the option trading data by comparing the size relationship between the third value of the electronic resource pre-paid by the unit number of options acquired in the option trading data and the fourth value of the electronic resource required to be paid by the unit number of options transferred in the transfer condition of the option to be selected, thereby realizing the trading of the option data.

In one embodiment, the method may further include the following steps s 61-s 63.

s61, creating a target tile in the tile chain.

s62, generating pause transition instruction information of the target block, the pause transition instruction information being used for instructing to pause the transition of the target option before receiving the uploading request of the first terminal for the target option.

s63, recording pause transition indication information into the target block.

In steps s 61-s 63, in the case of completing the option transaction, that is, in the case where the first terminal acquires 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 block chain, the computer device establishes the target block in the block chain, in which the information of the target option may be included, for example, the information of the terminal to which the target option belongs, the time of change of the attribution of the target option, and the first value of the electronic resource paid out for acquiring the target option, and so on. The computer device may cause the transfer of the target option to be suspended and record the suspend transfer instruction information into the target block before receiving an upload request of the first terminal for the target option, by generating suspend transfer instruction information of the target block. That is, after the suspend transfer instruction information of the target block is generated and before the upload request of the first terminal for the target option is received, the target option is suspended, that is, the terminal to which the target option belongs does not change any more during the time period.

In a possible implementation manner, as shown in fig. 4, for example, if the target option is option 1, after the first terminal acquires the target option, canceling the target option acquired by the first terminal shown in the display interface, and the display interface may be as shown in 7a in fig. 7, where fig. 7 is a schematic view of the display interface of the option to be transferred provided in the 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 shown in the showing interface, changing the number of the options 1 in the showing interface to be the difference between the number of the options 1 shown in the showing 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 presentation interface is 13.4K, and the number of options 1 in the presentation interface after the change is 13.4K-12.4K, which is 1K, the presentation interface may be as shown in fig. 7 b.

After the option trading is completed, the target block is established in the block chain, and the pause transfer indication information of the target block is generated, so that the problem that the option trading is disordered due to the fact that other terminals repeatedly acquire the target option can be avoided, and the efficiency of the option trading can be improved.

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.

s71, a transfer option number is acquired, which is an option number belonging to a mechanism corresponding to the second terminal and in a state to be transferred.

s72, if the third number is less than the transfer option number, determining that the first terminal is legitimate.

In steps s71 to s72, the computer device determines whether the first terminal is legitimate by acquiring the number of transfer options belonging to the institution corresponding to the second terminal and being in the state to be transferred, and by verifying whether the third number of options acquired by the first terminal in the option trade data is smaller than the number of transfer options. And if the third number of options acquired by the first terminal is smaller than 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. And if the third number of options acquired by the first terminal is larger than 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 does not have legality. 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 being in the state to be transferred, it is determined that the first terminal has validity. That is, the computer device determines whether the first terminal is legal by first acquiring the number of options that the institution corresponding to the second terminal currently needs to transfer, and by comparing the size between the number of options that the first terminal needs to acquire and the number of options that the institution needs to transfer. Optionally, it may also be determined whether the time in the option transaction data is consistent with the current time of the computer device, and so on, to determine that the first terminal is legitimate.

Optionally, before the block-link node system acquires the option trading data, the data server may verify the option trading data, to verify whether the terminal to which the option acquired by the first terminal belongs is the second terminal, whether the option acquired 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 whether the value of the electronic resource required to be paid out by the unit quantity of options acquired by the first terminal is greater than or equal to a second value of the electronic resource required to be paid out by the unit quantity of options acquired from the option information to be uploaded by the second terminal. The option that the first terminal needs to purchase is verified by the data server, so that the option purchased by the second terminal meets the specification, for example, the terminal to which the option purchased by the first terminal belongs may be legal, the purchased option is a saleable option, and electronic resources for the option purchased by the first terminal are sufficient, and the like. The option trading data of the first terminal is verified for the second time through the block link point system, so that the validity of the option trading data of the first terminal and the accuracy of option trading can be improved.
