[0040] Figure 1 It is a general system architecture design diagram for blockchain-based personalized customization;

[0041] Figure 2 It is a general system logic operation diagram for blockchain-based personalized customization. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those of ordinary skill in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0043] Embodiment:

[0044] As Figure 1 , the present invention provides a personalized customization general system based on blockchain, including: a user layer, an interface layer, an application service layer, a privacy computing layer, and a blockchain service layer.

[0045] The user layer is used to implement the interaction between the customer and the system, including functional units such as user registration and login, personal information management, order book display, demand tags, and business tracking.

[0046] The order book display unit displays information such as the products of the intended customization plan, the quotes and the current queue order quantities of the associated customization plan products and the lowest-price customization plan products. The products of the intended customization plan refer to the unique quotes provided by the enterprise based on the product customization plan selected by the user, as well as the input customization period and customization quantity. The associated customization plan products refer to the quotes and the current order quantities of the similar product customization plans provided by the enterprise around the product customization plan selected by the user from three dimensions: customization parameters, customization period, and customization quantity. The quotes are centered on the quote of the products of the intended customization plan, showing five price levels higher than the quote of the products of the intended customization plan, the current queue order quantity, and the corresponding customization plans upwards, and showing five price levels lower than the quote of the products of the intended customization plan, the current queue order quantity, and the corresponding customization plans downwards. The lowest customization plan products refer to the current lowest product price, the current order quantity, and the corresponding customization plan provided by the enterprise according to the input customization period and customization quantity of the user.

[0047] The demand tag unit classifies the user's demands into three types: large batch with few varieties, small batch with many varieties, and small workshop-style single-piece customization through knowledge graph technology and clustering analysis algorithm according to the product customization varieties and quantities submitted by the user, and assigns class keys. The large batch with few varieties means that the user's customized varieties are all within the existing variety range of the manufacturer, and the quantity of the customized products exceeds the minimum order quantity set by the company itself. The small batch with many varieties means that some or all of the user's customized varieties are outside the existing variety range of the manufacturer, and the quantity of the customized products does not exceed the minimum order quantity of the company's standard products. The small workshop-style single-piece customization means that the user completes the product design and purchases once or piece by piece.

[0048] The interface layer realizes the interaction between external organizations and the system, ensures the basic communication for business implementation and promotion by docking external IT systems, improves the auxiliary functions for users and relevant parties to use the system, and also avoids duplicate development of functional modules. It includes interface units such as production management, information authentication, and monitoring and supervision.

[0049] The production management interface unit refers to the interfaces related to the core links of project production management, including but not limited to industrial Internet platform interfaces, product data management systems, distributor management systems, enterprise resource planning systems, and manufacturing execution systems, etc.

[0050] The information authentication interface unit refers to the interfaces related to the trusted data provided by third parties, including but not limited to electronic signature anti-counterfeiting interfaces, timestamp anti-counterfeiting interfaces, qualification authentication interfaces, qualification level interfaces, other information source interfaces, etc.

[0051] The monitoring and supervision interface unit refers to the interfaces related to the business tracking permissions of relevant participants, including data deposit interfaces, service monitoring interfaces, data sharing interfaces, feedback query interfaces, and deposit chain query interfaces.

[0052] The application business layer implements the core functions of different business scenarios. Based on the key values of the demand tags determined by the user layer, it jumps to application modules such as large batch production with few varieties, small batch production with many varieties, and single-piece customization in small workshops.

[0053] The large batch production with few varieties application module, based on the specific needs of the user's "large batch production with few varieties" personalized customization, determines the optimal customizable product system and the minimum order quantity through quality matrix expansion technology and minimum order quantity algorithm, avoids customer default from both legal and financial aspects through RSA encryption and decryption algorithm and KYC authentication technology, sets up a customized product crowdfunding and price dynamic adjustment mechanism, and realizes the fixed evidence storage and secure sharing of key information and key behaviors in the whole process.

[0054] The small batch production with many varieties application module, based on the specific needs of the user's "small batch production with many varieties" personalized customization, builds a cloud production platform with a strict information flow control mechanism, optimizes the production enterprise's scheduling plan based on knowledge graph technology, determines the optimal customization plan based on user needs through white list and peer bidding mechanisms, avoids customer default from both legal and financial aspects, and promotes customer demand matching and confirmation through mechanisms such as KYC authentication, RSA encryption and decryption, feedback signing, and agile development.

[0055] The single-piece customization in small workshops application module, based on the specific needs of the user's "single-piece customization in small workshops" personalized customization, constructs a management authority price composed of "sponsor, nominator, supervisor, and organizer", matches the needs and resources at all levels through natural language processing technology and clustering analysis algorithm, realizes the bidding of all life cycle nodes of the product through the "candle auction" mechanism on the blockchain, and realizes the customer privacy protection under the participation of multiple parties through technologies such as zero-knowledge proof.

[0056] The privacy computing layer encrypts the underlying data and realizes the full life cycle protection of privacy information during multi-party collaboration, including functional modules such as data sharing and data calculation.

[0057] The data sharing module provides a data sharing solution with a privacy protection mechanism, and realizes secure data sharing and use in different application scenarios through technologies such as public key encryption, PRE, ABE, and homomorphic encryption, ensuring that sensitive data can be used with authorization.

[0058] The data calculation module, through technologies such as secure multi-party calculation, homomorphic encryption, PSI, zero-knowledge proof, TEE, and threshold signature, ensures data privacy when distributing, executing, verifying, and tracing data calculation tasks among one or more parties.

[0059] The blockchain service layer provides the basic functions of decentralized services, including node management, enterprise permission management, blockchain monitoring, blockchain browser, contract management, log / audit, private key custody, trusted data source, deposit service, alliance management, link-in management, private key recovery and other functional units.

[0060] The deposit service, taking advantage of the characteristics of the blockchain that information on the chain cannot be tampered with and is traceable, provides functions such as data storage and registration, data query and verification, data statistics and analysis. It collects all electronic data related to the user's confirmed order, calculates the hash digest of the key electronic data, uses a timestamp for electronic signature, constructs electronic evidence of the user's key behavior information and key data, and the national authorized electronic certification service institution conducts strict authenticity review on the order electronic data in the evidence chain according to the Electronic Signature Law and judicial logic. For the electronic data that passes the review, a third-party witness special seal is used for evidence fixation to generate reliable electronic evidence of the user's confirmed order. The key elements of the fixed electronic evidence are chained and stored on the blockchain, and are shared and traceable among nodes such as enterprises, trading platforms, official certification institutions, third-party testing institutions, and fund custody institutions.

[0061] Such as Figure 2 , during the operation of the blockchain-based personalized customization general system, its system operation logic is as follows:

[0062] The user layer collects the user's initial requirements, provides the corresponding order book display, and generates a requirement label key value after prompting the user to confirm the final requirements.

[0063] The application business layer determines the type of the user's single business according to the key value result passed by the user layer, and the optional items include large quantities of few varieties, small quantities of many varieties, and single-piece small workshops.

[0064] When the application business layer receives the key value of "few varieties in large quantities", it calls the internal functional units and external APIs to implement the process management of signing, design, production, and after-sales. Among them, the internal functional units called by the system are implemented in sequence according to the information flow: user KYC authentication, customized solution crowdfunding and dynamic adjustment mechanism, secondary user identity authentication, electronic signature, signature receipt, and payment of the deposit.

[0065] When the application business layer receives the key value of "many varieties in small quantities", it calls the internal functional units and external APIs to implement the process management of signing, design, production, and after-sales. Among them, the internal functional units called by the system are implemented in sequence according to the information flow: entering the white list, determining the customized solution based on the bidding mechanism, user confirmation form based on KYC and RSA, cloud production based on strict information flow control, project management based on agile production, and intelligent production scheduling based on the knowledge graph.

[0066] When the application business layer receives the key value of "single-piece production in small workshops", it calls the internal functional units and external APIs to implement the process management of signing, design, production, and after-sales. Among them, the internal functional units called by the system are implemented in sequence according to the information flow: building a decentralized autonomous organization, decomposing, classifying, and resource matching of requirements, bidding based on the "candle auction" mechanism, overall personalized customization solution, electronic signature, micro-opinion, external review, and user acceptance.

[0067] When communicating between the application business layer and the external API, all original data and return results need to be encrypted by the privacy computing layer.

[0068] All key data involved in the user layer, interface layer, and application business layer are summarized and transmitted to the blockchain service layer.

[0069] The blockchain service layer uploads the collected key data to the blockchain. The specific process includes: electronic data collection, hash digest calculation, timestamp, electronic signature, authenticity review, signature fixation, and distributed storage on the chain.

[0070] After the user layer generates demand tags, all process nodes of the personalized customization service are visually displayed in the user layer to facilitate users to synchronously track.
