[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure, but it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all the embodiments, and the schematic embodiments of the present disclosure and their descriptions are for interpreting the present disclosure, and do not unduly limit the present disclosure. All other embodiments that a person skilled in the art can obtain without creative efforts based on the embodiments of the present disclosure belong to the protection scope of the present disclosure.

[0029] It should be noted that in the specification, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another similar entity or operation, and do not necessarily require or imply any such actual relationship or order between those entities or operations. Furthermore, the terms "comprise", "comprises", or any other variant thereof are intended to cover a non-exclusive inclusion, whereby a process, method, article, or device that includes a set of elements includes not only those elements, but also other elements not expressly listed, or elements inherent in such process, method, article, or device. Unless further limited, an element limited by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0030] FIG. 1 is a flowchart of a blockchain-based transaction processing method according to an embodiment of the present disclosure. As shown in FIG. 1, the blockchain-based transaction processing method according to this embodiment is applied to a first client in a blockchain network, and the method includes steps S11 to S14.

[0031] In step S11, a live broadcast interface is entered by a trigger operation acting on the live broadcast link, and a user identifier is obtained.

[0032] In step S12, order information associated with the user identifier is obtained based on the live broadcast interface.

[0033] In step S13, multimedia data associated with the order information is determined.

[0034] In step S14, the order information and multimedia data are sent to each node in the blockchain network and recorded.

[0035] The transaction processing method according to this embodiment is applied to a live broadcast scene, and the first client may be a client applied to a buyer. When a user enters the client, the display interface of the client displays multiple live broadcast links to the user. When the user receives a trigger operation acting on a live broadcast link, the display interface jumps to a live broadcast interface corresponding to the live broadcast link, and a user identifier is obtained through the trigger operation, and the user identifier may be a user name, a user ID, etc.

[0036] In some implementations, obtaining order information related to the user identifier based on the live broadcast interface includes obtaining transaction information and a transaction time related to the user identifier, generating an order identifier based on the user identifier and the transaction time, determining a first order status based on the transaction information, and generating order information based on the order identifier and the first order status, where the first order status is awaiting shipment.

[0037] In some implementation methods related to step S13, it is necessary to first obtain a live broadcast video and target information related to the live broadcast video, divide the live broadcast video according to the target information, obtain at least one video clip, and store the divided video clips. Here, by dividing the live broadcast video according to the target information and reserving it in stages, a direct chain of evidence can be provided for handling issues such as subsequent disputes, and the processing efficiency is higher than that of the conventional technology of querying the live broadcast video.

[0038] It can be understood that the target information related to the live broadcast video may be product information, such as the number of products, the price of the product, etc. In this embodiment, the live broadcast video is divided according to the number of products, so that a video clip corresponding to each product in the live broadcast video is obtained, for example, a live broadcast video includes three products A, B, and C, and the live broadcast video is 30 minutes long, the video clips obtained by dividing the live broadcast video include video clip 1 of 0-10 minutes corresponding to product A, video clip 2 of 11-20 minutes corresponding to product B, and video clip 3 of 21-30 minutes corresponding to product C.

[0039] The step of determining multimedia data associated with the order information includes the steps of obtaining target object information listed in the order information, determining a target video clip corresponding to the target object information, obtaining communication data associated with a user identifier based on the target video clip, and obtaining multimedia data from the communication data and the target video clip.

[0040] In some implementation methods related to step S13, when determining a product in the order information, communication data related to the user ID is obtained from the video clip, and the communication data may be chat content, etc., and the communication data and the video clip are multimedia data.

[0041] In some implementations, the method according to this embodiment further includes the steps of: listening to first response information generated by the blockchain network invoking the first processing contract in the blockchain network; determining an order state in the order information based on the first response information; when the order state is a second order state and signature information is received, invoking the second processing contract to update the second order state in the order information to a third order state; and sending and recording the updated order information to each node in the blockchain network.

[0042] As can be understood, the first response information is triggered and generated by a seller client in the blockchain network, where the second order status is shipped, and the signature information is a user authentication signature, such as fingerprint authentication, face authentication, etc., and upon receiving the signature information, the second order status is changed to a third order status, and the third order status may be received.

[0043] In some implementations, the method of the present embodiment further includes the steps of obtaining complaint information; invoking a third processing contract based on the complaint information to update the third order state in the order information to a fourth order state; and sending and recording the complaint information and the updated order information to each node in the blockchain network.

[0044] As can be understood, the complaint information is the complaint information sent by the buyer's client after receiving the goods, and the fourth order status is Buyer Complaint.

[0045] In some implementations, the method of the present embodiment further includes: in the blockchain network, listening to second response information generated by the blockchain network invoking a fourth processing contract; determining a first processing result corresponding to the complaint information based on the second response information; when obtaining objection information fed back according to the first processing result, invoking a fifth processing contract according to the objection information to update the fourth order status in the order information to a fifth order status; and sending and recording the objection information and the updated order information to each node in the blockchain network.

[0046] It can be understood that the second response information is triggered and generated by the platform side of the blockchain network. If the buyer also has an objection to the first processing result, the buyer will again provide objection feedback based on the first processing result, and the fifth order state is in arbitration.

[0047] In some implementations, the method of this embodiment further includes a step of listening to third response information generated by the blockchain network invoking the sixth processing contract, in the blockchain network, and determining a second processing result corresponding to the objection information based on the third response information.

[0048] As can be understood, the third response information is triggered and generated by the arbitration institution in the blockchain network, and the second processing result is the final arbitration result sent by the arbitration institution.

[0049] FIG. 2 is a flowchart of a blockchain-based transaction processing method according to an embodiment of the present disclosure. As shown in FIG. 2, the blockchain-based transaction processing method according to this embodiment is applied to a second client in a blockchain network, and the method includes steps S21 to S24.

[0050] In step S21, listen to order information and multimedia data, including an order identifier and an order status, in the blockchain network.

[0051] In step S22, if the order status in the order information is a first order status, an imaging device is called to photograph a specified area to obtain photographic information, and a first processing contract is called to update the first order status in the order information to a second order status.

[0052] In step S23, a hash calculation is performed based on the order identifier to obtain an evidence identifier.

[0053] In step S24, electronic data evidence is generated based on the evidence identifier, the shooting information, the multimedia data, and the updated order information, and the electronic data evidence is sent to each node in the blockchain network for recording.

[0054] In some implementation methods related to step S22, calling an imaging device to photograph a specific area and obtain shooting information may be calling an imaging device to photograph an area where the product is packaged, and the shooting information is image information or video information when the product is packaged.

[0055] In some implementations related to step S23, a technology called digital summarization is adopted, which mainly adopts the HASH function, and the calculation process of this technology is as follows: input a string of a non-fixed length (i.e., the order identifier), perform calculations using the HASH function, and return a string of a fixed length (i.e., the evidence identifier).

[0056] Digital digests are used to convert a message of any length into a short message of a fixed length, and are similar to a function that uses the message as an independent variable, i.e., a hash function. Digital digests use a one-way hash function to "summarize" the plaintext that needs to be encrypted into a ciphertext of a fixed length (128 bits). This ciphertext is also called a digital fingerprint and has a fixed length. Also, if the plaintext that is digested into the ciphertext is different, the result will always be different, and if the plaintext is the same, the digest must be the same.

[0057] FIG. 3 is a flowchart of a blockchain-based transaction processing method according to an embodiment of the present disclosure. As shown in FIG. 3, the blockchain-based transaction processing method according to this embodiment is applied to a first processing terminal in a blockchain network, and the method includes steps S31 to S34.

[0058] In step S31, the blockchain network is listened to for complaint information containing an order identifier.

[0059] In step S32, a hash calculation is performed based on the order identifier to obtain a target evidence identifier.

[0060] In step S33, the local electronic data evidence is traversed to obtain the target electronic data evidence corresponding to the target evidence identifier.

[0061] In step S34, the complaint information is analyzed based on the target electronic data evidence, a processing result is obtained, and the processing result is sent to each node in the block chain network for recording.

[0062] In this embodiment, the complaint information may include complaint text, complaint pictures, complaint videos, and so on.

[0063] In some implementations related to step S32, a technology called digital summarization is adopted, which mainly adopts the HASH function, and the calculation process of this technology is as follows: input a string with a non-fixed length (i.e., the order identifier), perform calculations using the HASH function, and return a string with a fixed length (i.e., the target evidence identifier).

[0064] In some implementation means related to step S33, the target electronic data evidence corresponding to the target evidence identifier includes shooting information, multimedia data and updated order information, the shooting information includes video information or product images when packaging the complained-about product, the multimedia data includes live broadcast clips and communication data corresponding to the complained-about product, where the communication data may be text data.

[0065] In some implementation means related to step S34, a first comparison result can be obtained by comparing the multimedia information with the complaint picture or the complaint video, and a second comparison result can be obtained by comparing the complaint text with the communication data, and a final processing result is obtained from the first comparison result and the second comparison result.

[0066] In some implementation methods, a feature distance between the complaint picture and the product image included in the multimedia information is obtained, the feature distance being the distance between the features of the images, and based on the obtained feature distance, the image similarity between the complaint picture and the product image is determined as the first comparison result from a predetermined correspondence relationship between the feature distance and the image similarity.

[0067] Note that image similarity tends to decrease as the feature distance increases; when the feature distance is 0, the image similarity is 1, and when the feature distance tends to infinity, the image similarity tends to become 0.

[0068] In addition, when obtaining the second comparison result by comparing the complaint text with the communication data, a part-of-speech level analysis may be performed on the complaint text to determine a first emotion index, a part-of-speech level analysis may be performed on the communication data to determine a second emotion index, and the second comparison result may be obtained by comparing based on the first emotion index and the second emotion index.

[0069] As an understandable example, the complaint text is subjected to text preprocessing, sentence segmentation, and word segmentation using a word segmentation algorithm, the word segmentation text is obtained, the word segmentation sentence is input to a trained word vector model to obtain a first word vector, and a first sentiment index is determined by the first word vector, the communication data is subjected to text preprocessing, sentence segmentation, and word segmentation using a word segmentation algorithm, the word segmentation text is obtained, the word segmentation sentence is input to a trained word vector model to obtain a second word vector, and a second sentiment index is determined by the second word vector, where the sentiment index is calculated by performing weighted addition based on the part of speech of the word vector. Next, the first sentiment index and the second sentiment index are compared to obtain a sentiment difference, and the sentiment difference is used as a second comparison result.

[0070] In some implementations, when determining a processing result based on the first comparison result and the second comparison result, if the image phase velocity is smaller than a predetermined similarity and the emotional difference is larger than a predetermined threshold, it may be determined that the complaint information is valid, and corresponding processing measures may be taken according to the complaint information.

[0071] FIG. 4 is a flowchart of a blockchain-based transaction processing method according to an embodiment of the present disclosure. As shown in FIG. 4, the blockchain-based transaction processing method according to this embodiment is applied to a second processing terminal in a blockchain network, and the method includes steps S41 to S44.

[0072] In step S41, the order identifier is placed in the blockchain network, and objection information fed back from the first processing result is listened to.

[0073] In step S42, a hash calculation is performed based on the order identifier to obtain a target evidence identifier.

[0074] In step S43, the local electronic data evidence is traversed to obtain the target electronic data evidence corresponding to the target evidence identifier.

[0075] In step S44, the dispute information is analyzed based on the target electronic data evidence to obtain a second processing result, and the second processing result is sent to each node in the block chain network for recording.

[0076] In some implementations relating to step S41, the objection information may include complaint text, complaint picture, complaint video, and so on.

[0077] In some implementations related to step S42, a technology called digital summarization is adopted, which mainly adopts the HASH function, and the calculation process according to this technology is as follows: input a string with a non-fixed length (i.e., the order identifier) ​​and return a string with a fixed length (i.e., the target evidence identifier).

[0078] In some implementations related to step S43, a technology called digital summarization is adopted, which mainly adopts the HASH function, and the calculation process of this technology is as follows: input a string with a non-fixed length (i.e., the order identifier), perform calculations using the HASH function, and return a string with a fixed length (i.e., the target evidence identifier).

[0079] In some implementation means related to step S44, the analysis method in the above embodiment may be adopted as the analysis method when analyzing the objection information based on the target electronic data evidence, and the target electronic data evidence and the objection information may be sent to a designated terminal. By sending the target electronic data evidence and the objection information to the designated terminal, the examiner can make an analysis judgment and input the judgment result into the designated terminal, so it is also necessary to receive instruction information and determine the second processing result based on the instruction information.
