[0084] based on Figure 1 With reference to the hardware structure shown, the first embodiment of the present invention provides a method for processing sports transfer transactions.

[0085] Reference Figure 2 , Figure 2 It is a flowchart diagram of the first embodiment of the sports transfer transaction processing method of the present invention.

[0086] The embodiment of the present invention provides an embodiment of a method for processing a sports transfer transaction. It should be noted that although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than that shown here. Specifically, the method for processing a sports transfer transaction in this embodiment includes:

[0087] Step S10: upon receiving an encrypted transfer request carrying a third-party ID sent by a third-party sports club chain through the blockchain node, decrypting the encrypted transfer request according to a first key matched by the third-party sports club chain to obtain the third-party ID;

[0088] It should be noted that the sports transfer transaction processing method proposed in the present invention is applied to a sports club chain in a sports management system based on blockchain, wherein the sports management system based on blockchain includes multiple third-party sports club chains in addition to the sports club chain involved in the present invention, and the sports club chain includes blockchain nodes corresponding to each third-party sports club chain. In addition, it should be further noted that the above-mentioned sports management system based on blockchain runs on Ethereum, and the third-party sports club chains in the above-mentioned sports management system based on blockchain exchange information and store and record information based on Ethereum's blockchain technology, thereby ensuring the authenticity and privacy of the information.

[0089] Specifically, the sports club chain is a blockchain system composed of multiple nodes, wherein the sports club chain includes blockchain nodes corresponding to each third-party sports club chain, sports operation nodes, athlete nodes, athlete training nodes, investor nodes, and decision-making nodes for participating in the approval of any matter, etc. It is easy to understand that in the process of transfer transactions between clubs, there may be a risk of information leakage in the transfer transaction information. For example, when the two clubs are conducting face-to-face negotiations, they are known by entertainment reporters and disclosed in advance, thereby causing some adverse effects such as damage to the mentality of the athletes involved in the transfer transaction or damage to the club's investment. At present, in order to solve the risk of information leakage in transfer transaction information, some clubs use remote encrypted transaction methods such as encrypted emails or encrypted calls to negotiate instead of face-to-face negotiations, so as to ensure the privacy of transfer transactions. However, the current information cracking technology is becoming more and more mature. Even if the transfer transaction is conducted through encrypted emails, there is still a risk of being cracked by malicious cracking software, which causes serious troubles to the clubs that need to conduct transfer transactions. Therefore, in this embodiment, in order to improve the security of encrypted transfer transactions, the information interaction between multiple sports clubs is linked together through blockchain, thereby ensuring the security of transfer transactions.

[0090] In addition, it is easy to understand that since the sports club chains are connected to each other through blockchain nodes, when a third-party sports club chain needs to conduct a transfer transaction of a professional athlete, a transfer transaction request can be sent through the blockchain node corresponding to the third-party sports club chain. In addition, in order to ensure the authenticity of the information and the privacy of the transaction information, when sending a transfer transaction request, there is no need to directly disclose specific transaction information, such as the athlete information corresponding to the transfer transaction. In this embodiment, the transfer transaction is performed in a ciphertext manner using an ID identifier. Specifically, the above-mentioned third-party ID identifier refers to the information code of the third-party athlete, such as the number of the third-party athlete in the club or the storage address for storing the third-party athlete information, etc. Preferably, in this embodiment, the ID identifier refers to the storage address where the user stores the athlete information or transaction information, wherein the transaction information includes the athlete information and transaction plan corresponding to the transfer transaction, etc.

[0091] In addition, in some embodiments, during the transfer transaction using the ciphertext method of the ID identifier, the ID identifier may be in danger of being cracked. Therefore, in this embodiment, before sending the transfer request carrying the third-party ID identifier, the third-party sports club encrypts the transfer request carrying the third-party ID identifier using the first key of the third-party sports club chain, and sends the encrypted transfer request. Specifically, the above-mentioned first key refers to the private key in the key pair randomly generated by the third-party sports club chain. In addition, it should be noted that in order to ensure the executability of data encryption interaction based on the key, in this embodiment, both parties to the transfer transaction store the other party's key pair, that is, the sports club chain involved in this embodiment stores not only the locally generated key pair, but also the other party's key pair for encrypted information interaction.

[0092] Specifically, for ease of understanding, before the step of receiving the encrypted transfer request carrying the third-party ID sent by the third-party sports club chain through the blockchain node, the step further includes:

[0093] Randomly generate a local key pair, and send a key exchange notification message to the third-party sports club chain through the blockchain node corresponding to the third-party sports club chain to obtain the first key fed back by the third-party sports club chain;

[0094] Generate a first encrypted key exchange response message carrying the local key pair according to the first key, and send the first encrypted key exchange response message through the blockchain node corresponding to the third-party sports club chain, wherein the third-party sports club chain decrypts the first encrypted key exchange response message according to a second key matched with the first key to obtain the local key pair, and generates and feeds back a second encrypted key exchange response message carrying the second key according to the local public key in the local key pair;

[0095] The key exchange response second encrypted message is received, and the key exchange response second encrypted message is decrypted by using a local private key in the local key pair to obtain the second key.

[0096] In this step, before sending a request carrying a third-party ID, the third-party sports club chain may first send a transfer transaction notification message so that both parties can obtain each other's keys through the transaction notification message. Specifically, after receiving the transfer transaction notification message sent by the third-party sports club chain, a local key pair is randomly generated, and after the local key pair is randomly generated, a key exchange notification message is sent to the third-party sports club chain to notify the other party that key exchange can be carried out.

[0097] Step S20: Obtain the total IP value of the third-party athlete whose third-party ID matches the third-party athlete from the blockchain, and obtain the degree of fit between the total IP value of each local athlete and the total IP value of the third-party athlete, so as to determine the target local athlete through the degree of fit;

[0098] Specifically, the above-mentioned total value of the athlete's IP refers to the total value of the IP composed of the athlete's sports attributes (for example, for a basketball player, whether he belongs to a forward, center or guard), competition ability (for example, for a power forward, his success rate in rebounding), and the commercial value that the athlete can bring. The above-mentioned degree of fit refers to the value ratio of the total value of the local athlete's IP to the total value of the third-party athlete's IP. In addition, in this embodiment, in order to ensure the authenticity of the information, the total value of the athlete's IP and the athlete's information are all recorded in the blockchain.

[0099] In addition, for ease of understanding, this embodiment specifically describes the above-mentioned solution of determining the target local athlete through the degree of fit:

[0100] Selecting the local athlete corresponding to the maximum degree of fit as the first transfer transaction object, and determining the voting result corresponding to the first transfer transaction object according to the preset smart contract;

[0101] If the voting result meets the preset result requirement, determining the first transfer transaction object as the target local athlete; and,

[0102] If the voting result does not meet the preset result requirements, a second transfer transaction object is selected based on a gradient descent method of fit, and a target compensation plan matching the second transfer transaction object is generated until it is determined according to the preset smart contract that the voting results corresponding to the second transfer transaction object and the target compensation plan meet the preset result requirements, and the second transfer transaction object corresponding to the voting results that meet the preset result requirements is used as the target local athlete.

[0103] In this step, the above-mentioned preset smart contract is a smart contract specified when the sports club chain is constructed, such as which nodes in the sports club chain have voting rights and voting mechanisms. In this embodiment, it is preferred to first select the local athlete corresponding to the maximum fit as the first transfer transaction object. If the voting result corresponding to the first transfer transaction object is determined to meet the preset result requirements according to the preset smart contract, otherwise, the second transfer transaction object is selected by a gradient descent of fit, and a corresponding compensation plan is generated until the voting result meets the preset result requirements.

[0104] Step S30: Generate an encrypted transaction request carrying the target local ID according to the second key;

[0105] Step S40: sending the encrypted transaction request to the third-party sports club chain through the blockchain node, and receiving the transaction result fed back by the third-party sports club chain;

[0106] Step S50: If the transaction result is approval of the transfer transaction, the transfer transaction certificate is generated in collaboration with the third-party sports club chain, and the transfer transaction certificate is recorded in the blockchain according to the third-party ID identifier and the target local ID identifier.

[0107] Specifically, the above-mentioned target local ID identifier refers to the storage address used to store local athlete information corresponding to the transfer transaction and specific transaction details such as the transaction agreement, and the above-mentioned transfer transaction certificate refers to the certificate that records the specific transaction details, such as the transaction contract, transaction object, etc.

[0108] That is, in this embodiment, when conducting a transfer transaction, there is no need to directly disclose specific transaction information, such as the athlete information corresponding to the transfer transaction. In this embodiment, the transfer transaction is conducted in a ciphertext manner using an ID identifier. Since the security of the transfer transaction is ensured, further, in this embodiment, when the transfer transaction is completed, that is, the transaction result fed back by the third-party sports club chain is the agreement to the transfer transaction, a transfer transaction voucher will be generated. Therefore, before the transaction is completed, other parties cannot know the specific transaction process of the entire transaction, and the transfer transaction voucher is recorded in the blockchain to ensure that it can be traced back when problems arise in subsequent transactions, thereby improving the security of the encrypted transaction process.

[0109] It should be understood that the above is only an example and does not constitute any limitation to the technical solution of the present invention. Those skilled in the art can make settings based on needs in actual applications, and they are not listed one by one here.

[0110] In this embodiment, when an encrypted transfer request carrying a third-party ID identifier is received from a third-party sports club chain through the blockchain node, the encrypted transfer request is decrypted according to a first key matched by the third-party sports club chain to obtain the third-party ID identifier; the third-party athlete IP total value of the third-party athlete matched by the third-party ID identifier is obtained from the blockchain, and the degree of fit between the total IP value of each local athlete and the total IP value of the third-party athlete is obtained to determine the target local athlete through the degree of fit; an encrypted transaction request carrying the target local ID identifier is generated according to a second key; and the encrypted transaction request is sent to the third-party sports club chain through the blockchain node. Club chain, and receive the transaction result fed back by the third-party sports club chain; if the transaction result is to agree to the transfer transaction, then cooperate with the third-party sports club chain to generate a transfer transaction certificate, and record the transfer transaction certificate into the blockchain according to the third-party ID identifier and the target local ID identifier. Compared with the technical solution of the encrypted transaction method through encrypted email or encrypted phone in the prior art, the present invention uses the ciphertext information transmission method of ID identifier and combines with decentralized blockchain technology to perform encrypted transactions. Therefore, the specific transaction certificate is generated after the entire transaction is completed, that is, other parties cannot know the specific transaction process of the entire transaction before the transaction is completed, thereby improving the security of the encrypted transaction process.

[0111] Furthermore, based on the first embodiment of the sports transfer transaction processing method of the present invention, a second embodiment of the sports transfer transaction processing method of the present invention is proposed.

[0112] Reference Figure 3 , Figure 3 It is a flow chart of a second embodiment of a sports transfer transaction processing method of the present invention;

[0123] The total value of the local athlete IP corresponding to the local ID is adjusted according to the audience preference value and the operating income, and the adjusted total value of the local athlete IP is stored in the blockchain according to the local ID.

[0124] It should be noted that the above-mentioned sports club chain includes event nodes corresponding to the event alliance chain, wherein the event alliance chain includes event audience nodes and event operation nodes, wherein the above-mentioned audience favorite value refers to audience support, for example, there are 2,000 spectators in the current event who buy tickets to watch the athletes matched by athlete node a in sports club chain A, and the current event has 20,000 spectators, then the audience favorite value of athlete node a is 10%, in addition, it should be noted that when the event audience node in the event alliance chain of the present invention purchases the admission ticket corresponding to the event node, in addition to the ticket purchase window, the ticket purchase platform may also include a ticket purchase reason window, wherein the ticket purchase reason window is provided with a check box for athletes participating in the event, in which users can check the athletes they support, thereby obtaining the audience favorite value, in addition, the above-mentioned operating income refers to the ticket income, derivative income and advertising investment income brought by the athlete node in the current event.

[0125] In this embodiment, in addition to evaluating the total IP value of the athlete based on the initial value, training value and investment value of the local athlete in the sports club chain, the total IP value of the athlete is also adjusted by the audience preference value fed back by the event audience node corresponding to the local athlete node in the event alliance chain and the operating income fed back by the event operation node, thereby ensuring the comprehensiveness of the total IP value of the athlete, and executing the above process through blockchain technology to ensure the authenticity of the information.
