Description

Technical Field

[0001] This invention relates to the field of big data processing, and in particular to a futures-spot integrated electronic contract management and intelligent logistics delivery system and method. Background Technology

[0002] Spot commodity trading is a crucial link connecting production and consumption, involving extremely complex business processes, including price negotiation, contract signing, payment settlement, goods pickup, and logistics distribution. Compared to the highly electronic trading model of the futures market, the overall informatization level of spot trading has long lagged far behind, with many business processes still relying on offline manual methods. This phenomenon is prevalent in commodities such as non-ferrous metals, ferrous metals, energy chemicals, and agricultural products.

[0003] At the contract management level, spot trading contracts are typically drafted, printed, mailed, or signed in person in paper form. The entire signing process can take anywhere from several days to several weeks. Manual entry of contract terms often results in clerical errors, and the archiving, retrieval, and compliance auditing of paper contracts are extremely inefficient, with the potential risk of forgery and alteration. In complex spot transactions involving multiple parties (buyers, sellers, guarantors, warehousing providers, banks, etc.), the coordination and transfer of paper contracts presents particularly significant challenges.

[0004] At the logistics delivery level, the physical delivery of bulk commodities involves several key stages, including warehouse release, transportation arrangements, quality inspection and sampling, and transfer of ownership. In the traditional model, delivery information is transmitted via telephone or paper delivery slips, resulting in opaque and untraceable logistics status; neither the buyer nor the seller can monitor the real-time movement of goods during transit; and the lack of system linkage between warehouse entry and exit and contract settlement easily leads to disputes such as unclear ownership and asynchronous payment and delivery.

[0005] Meanwhile, the physical delivery process in the futures market and the logistics and delivery business in the spot market are completely independent under the traditional framework. There is a lack of systematic coordination between the cancellation of futures warehouse receipts and the performance of spot contracts, further increasing the operational complexity of companies integrating futures and spot markets. Therefore, the main technical deficiencies in the management and logistics delivery of commodity spot contracts are as follows: 1. The entire contract process is offline, resulting in serious inefficiencies and lack of compliance. The entire process of spot trading contracts, from drafting to final archiving, relies on manual offline operations, with an average signing cycle of 3-5 working days per contract; the efficiency of archiving and reviewing paper contracts is extremely low, making it difficult to provide evidence in case of disputes; the error rate of manually entering contract terms is about 3-5%, and commercial disputes caused by ambiguity in terms account for a high proportion; the collaborative flow in multi-party signing scenarios cannot be tracked, easily leading to omissions or duplicate signing. 2. The systematic application of electronic signatures in the commodity sector is severely lacking. The current bulk commodity industry generally lacks professional electronic signature solutions that comply with national cryptographic standards (SM2 / SM3 algorithms); in complex signing scenarios involving four or more parties, such as buyers, sellers, guarantors, and warehouse supervisors, there are significant gaps in the technical implementation of multi-party online collaborative signing; the legal validity and evidence chain integrity of electronic signatures are not widely recognized within the industry. 3. Contract data silos, disconnected from transaction and financial systems. Key terms of signed contracts (variety, quantity, unit price, payment terms) cannot be automatically fed back to the transaction and financial systems, requiring manual re-entry, making data consistency difficult to guarantee; there is a lack of real-time linkage between contract execution progress, order status, and payment receipt, making it impossible to provide timely warnings of contract performance risks. 4. Lack of transparency in logistics information and absence of cargo status tracking. After bulk commodities are picked up, the location and status of goods during transportation cannot be monitored in real time; both buyers and sellers, as well as regulatory agencies, rely on proactive reports from logistics providers for information, which is often delayed and difficult to verify; there is a lack of automatic early warning mechanisms for risk events such as abnormal delays and cargo damage, often resulting in delayed handling. 5. Disorganized management of delivery orders, leading to significant risks to ownership. Traditional paper delivery orders are susceptible to forgery, and warehouse verification methods are limited. Issues such as multiple deliveries from a single order (copying and using the same paper delivery order) and untimely updates on ownership transfers frequently occur. Key information such as the time, quantity, and responsible personnel for delivery operations lacks reliable digital records, making evidence collection difficult in case of disputes. 6. Disconnect between futures physical delivery and spot delivery processes. There is a lack of system linkage between the cancellation and release of futures warehouse receipts and the delivery instructions for spot contracts. The process of transferring goods from the warehouse to the spot market after futures delivery requires manual coordination, and time and information gaps can easily lead to confusion regarding ownership and disputes over payment. 7. Lack of AI-powered intelligent contract review capabilities. Commodity spot contracts are highly specialized, involving complex content such as quality standards, measurement methods, pricing clauses, and liability for breach of contract. Existing systems rely entirely on manual review of contract clauses, resulting in low efficiency and the potential to overlook key risks. Abnormal clauses (such as pricing methods that violate industry practices or overly lenient breach of contract clauses) cannot be automatically identified.8. Quality inspection results are disconnected from the contract performance system. Spot delivery usually requires a quality inspection report from a third-party quality inspection agency. However, the entry of quality inspection results, automatic comparison and verification with contract terms, and judgment of whether quality breach clauses are triggered are currently all done manually, which is inefficient and subject to human error risks. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a futures and spot integrated electronic contract management and intelligent logistics delivery system and method, which solves the deficiencies of the prior art.

[0007] The objective of this invention is achieved through the following technical solution: a futures-spot integrated electronic contract management and intelligent logistics delivery system, the system comprising: AI-powered intelligent contract generation and review module: used for intelligent drafting and compliance review of contracts; Multi-party electronic signature collaboration module: used to enable online collaborative signing by multiple parties; Blockchain contract storage and supervision interface module: used for long-term legal validity and compliance supervision of electronic contracts; Digital pick-up code and anti-counterfeiting verification module: used to realize the digitization and anti-counterfeiting of pick-up vouchers; Intelligent logistics end-to-end tracking module: used to realize full-process visual tracking from the warehouse to the buyer's receipt of goods; Integrated Futures and Spot Delivery Module: Used to achieve integrated settlement of physical delivery of futures contracts and physical delivery of goods in the spot market.

[0008] The AI-powered smart contract generation and review system specifically implements the following functions: Intelligent contract template management: Built-in standard contract template library for major commodities, including various contract types, and supports dynamic configuration by commodity and transaction mode; Automatic data population for transactions: After a contract is confirmed, key elements are automatically extracted from the transaction database and filled into the corresponding contract template fields; AI-powered intelligent review of contract terms: It uses a large AI model to perform deep semantic analysis on contract texts, and conducts risk scanning from compliance review, abnormal clause identification, missing item check, and consistency check. The review results are presented as a risk score and a list of specific risk warnings. Contract version management: Records the complete modification history of the contract. Each modification generates a new version and marks the modifier, modification time, and a summary of the modification content. Both the buyer and seller can view the complete version change record, ensuring that the contract negotiation process is transparent and traceable.

[0009] The multi-party electronic signature collaboration module specifically implements the following functions: National cryptographic-level identity authentication and signature: Integrates a CA certificate system that conforms to national cryptographic standards. Enterprise users can apply for electronic signature certificates after completing real-name authentication with their business license and legal representative information; the signature operation uses the SM2 asymmetric encryption algorithm to generate digital signatures. Multi-party signing process orchestration: Supports flexible configuration of multi-party signing processes, including sequential signing, parallel signing, and conditional signing. Signing invitations are pushed synchronously through three channels: in-system messages, SMS, and email. Real-time tracking of signing progress: The system generates a signing status dashboard for each contract, displaying the signing status of all parties, signing timestamp, and signing device information in real time; a signing timeout reminder mechanism is also set up. Refusal and objection handling: If either party refuses to sign, they must fill in the reason for refusal in the system, and the system will simultaneously notify the other signatories of the reason for refusal; the buyer and seller can initiate contract modification negotiations in the system, and the modified new version will re-enter the signing process.

[0010] The blockchain contract notarization and supervision interface module specifically implements the following functions: Contract hash on-chain notarization: After all parties have signed the contract, the system calculates the SHA-256 hash value of the contract FDP file and uploads the hash value, signing completion timestamp, and certificate serial number of each signatory to a trusted blockchain node for notarization. After notarization is completed, a unique notarization number and blockchain transaction hash are returned and written to the contract details page. Real-time contract integrity verification: At any time, users or regulators can initiate contract integrity verification through the system. The system recalculates the SHA-256 hash value of the current contract file and compares it with the hash value stored on the chain. If they are completely consistent, the system outputs that the verification is successful. If they are inconsistent, the system outputs a tampering alarm and locks the contract status. Regulatory interface reservation: The system reserves a data interface for regulatory agencies, which can support querying the signing records, evidence storage information and performance status of designated contracts when authorized by the regulator, and support the export of compliance reports as required by the regulator. Long-term contract archiving management: The system archives completed contracts in a structured manner, supports fast retrieval by contract number, signing date, product type, counterparty, and contract status, and the archived data is stored in encrypted form.

[0011] The digital pickup code and anti-counterfeiting verification module specifically implements the following functions: Dynamic pickup code generation: After the contract is signed and payment is confirmed, the system automatically generates a unique digital pickup code. The pickup code consists of a 32-character random string and is strictly bound to the contract number, product type, quantity, validity period, and designated pickup warehouse. The pickup code is stored in an encrypted manner and can only be viewed by the contract buyer. Pickup code validity period and usage control: The default validity period of the pickup code is the pickup time window agreed in the contract. It will automatically expire after the expiration. The pickup code is for one-time use. Once the verification is successful, it will be marked as used to prevent the risk of multiple pickups with one code. If you need to pick up goods in batches, the system supports splitting and generating multiple sub-pickup codes. Each sub-pickup code corresponds to an independent quantity and validity period. Warehouse-side barcode verification: Warehouse administrators scan the pickup code using the system's mobile terminal or a dedicated barcode scanning device. The system verifies the validity, type, quantity, and identity of the pickup code in real time. Once verification is successful, the system will immediately link with the WMS to generate an outbound instruction. Full warehouse record of pickup: The system records a complete operation log of pickup verification, including key information such as verification time, verification location, operator number, quantity issued, and photos of the goods' appearance, forming a complete digital evidence chain for pickup.

[0012] The intelligent logistics end-to-end tracking module specifically implements the following functions: Multi-logistics platform API integration: The system integrates the API interfaces of logistics service providers, supporting real-time retrieval of waybill status, vehicle GPS location, and estimated arrival time; Full lifecycle management of goods status: The system defines a standardized goods flow status chain, including contract signing completion → payment confirmation → pickup code generation → warehouse preparation → awaiting pickup / shipment → in transit → arrived → buyer's signature confirmation → delivery completion. Each status change is recorded with a timestamp, and both the buyer and seller can view it in real time through the App / PC. AI Logistics Anomaly Warning: The system establishes a normal logistics timeliness benchmark model based on historical logistics data. When the actual transportation time exceeds the set value of the benchmark timeliness, a delay warning is triggered and pushed to both the buyer and seller. When the system detects that the waybill status has not been updated for a long time, it automatically initiates a logistics provider query request. Online quality inspection results integration: When the buyer receives the goods, they upload the quality inspection report issued by a third-party quality inspection agency to the system. The system uses OCR technology to automatically extract key indicators from the quality inspection report and automatically compares them with the quality standards agreed in the contract. If the test value exceeds the range allowed by the contract, the system automatically marks it as a quality objection status.

[0013] The integrated futures and spot delivery module specifically implements the following functions: Automatic matching of futures warehouse receipts and spot contracts: The system automatically matches the physical delivery warehouse receipts in futures positions with spot purchase contracts. After successful matching, the system prompts the operator for confirmation. After confirmation, the futures warehouse receipt cancellation process and the spot delivery process are started simultaneously. Delivery warehouse WMS linkage: The system establishes a data interface with the WMS system of major futures delivery warehouses to obtain the warehouse receipt cancellation progress, actual cargo release time and quantity in real time. After the futures warehouse receipt cancellation is completed, the system automatically updates the cargo status of the spot contract and generates the corresponding spot delivery code. Payment and delivery settlement are linked: The system supports configuring automatic triggering conditions for payment settlement; Delivery Completion Report: After the entire futures and spot delivery process is completed, the system automatically generates a complete delivery report, which includes: basic contract information, completion time nodes of each stage, goods inspection results, delivery records, payment settlement status and blockchain evidence number. The report is generated in PDF format and simultaneously pushed to both the buyer and seller and relevant regulators.

[0014] A method for integrating futures and spot electronic contract management and intelligent logistics delivery, the method comprising: S1. After the spot transaction is confirmed and the contract is automatically generated, conduct a legal compliance review of the contract, AI identification of abnormal clauses, and field consistency verification. Ideally, generate a contract review report that includes a risk score, a list of risk clauses, and modification suggestions. S2. After the review is approved, multi-party electronic signature collaboration is carried out and the contract is stored on the blockchain. S3. After payment is confirmed and pickup code is generated, the warehouse prepares and confirms the goods for shipment. S4. Perform real-time logistics tracking and issue anomaly warnings when warning conditions are triggered. S5. After the buyer completes the quality inspection, the buyer uploads the third-party quality inspection report to the system and performs integrated processing of futures and spot delivery. S6. Archive the documents after the handover is completed.

[0015] The blockchain contract notarization includes: Calculate the SHA-256 hash value as H_contract = SHA256, and construct the evidence storage data packet as {Contract No., H_contract, Signing Completion Timestamp, List of CA Certificate Serial Numbers of Each Signatory, Contract Type, Variety Code, Quantity, Amount}; Upload the evidence storage data package to a trusted blockchain node to obtain the blockchain transaction hash TxHash and block height BlockHeight; Write {TxHash, BlockHeight, Evidence Preservation Time} into the contract details database and automatically append an evidence preservation certificate page to the last page of the contract PDF. After the evidence preservation is completed, the system will push a contract evidence preservation success notification to each signatory.

[0016] The steps in S4 include: If the buyer entrusts a logistics provider for transportation, the system receives the waybill information through the logistics API, retrieves the waybill status update every 10 minutes, and displays the GPS location and transportation progress in real time on the map on the order details page of both the buyer and seller; The system calculates the normal delivery time benchmark T_baseline for the current route based on historical logistics data. If the actual transportation time exceeds T_baseline × 1.2, a delay warning is triggered. If the status of the waybill has not been updated for more than 6 hours, the system will automatically send a status query request to the logistics provider and push a notification to both parties. After the goods arrive at the location designated by the buyer, the buyer will perform a receipt confirmation operation in the system and simultaneously upload photos of the goods and preliminary quality inspection notes.

[0017] The present invention has the following advantages: 1. The entire process of spot contract management has been migrated online, from draft generation to signing and archiving, all of which are digitized. The contract signing cycle has been shortened from an average of 3-5 working days to less than 2 hours. Contract terms are automatically filled in to eliminate manual input errors, compliance is greatly improved, and contract management and operating costs are reduced by about 65%.

[0018] 2. A multi-party collaborative electronic signature system based on the SM2 / SM3 national cryptographic algorithm was constructed, which supports up to 10 parties to sign online in parallel or sequentially. The signing process is fully traceable, and the electronic signature has full legal effect. Compared with paper contracts, the efficiency of multi-party signing is improved by about 8 times.

[0019] 3. The introduction of a blockchain contract notarization mechanism ensures that contracts are immediately notified on the blockchain after signing, allowing for online verification of contract integrity at any time and effectively preventing contract tampering and forgery. In historical practice, contract disputes that have occurred have been resolved within 5 minutes through blockchain notarization verification, improving the efficiency of contract dispute resolution by approximately 90%.

[0020] 4. Real-time tracking of goods from shipment to receipt has been achieved, allowing both buyers and sellers to view the latest location and status of goods at any time via App / PC; the AI ​​anomaly warning mechanism reduces the average handling time for logistics delays from 12 hours to less than 2 hours.

[0021] 5. The system barriers between physical delivery of futures and logistics and pickup of spot goods have been broken down. The cancellation of futures warehouse receipts and the generation of spot pickup codes are automatically linked. The overall process of futures and spot delivery has been shortened from 3-5 days, which originally required manual coordination of multiple systems, to less than 1 day with automatic system linkage, greatly improving operational efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. The present invention will be further described below with reference to the accompanying drawings.

[0028] One embodiment of the present invention relates to a futures-spot integrated electronic contract management and intelligent logistics delivery system. Through AI intelligent contract generation and review, national cryptographic-level multi-party electronic signature collaboration, blockchain contract storage, digital delivery code management, real-time tracking of logistics throughout the entire process, and integrated linkage of futures and spot delivery, it realizes digital, intelligent, and reliable management of the entire chain of bulk commodity spot transactions from contract signing to goods delivery, eliminating information silos and operational risks in the traditional model.

[0029] like Figure 1 As shown, the system mainly consists of the following modules: I. AI-powered intelligent contract generation and review module, responsible for intelligent drafting and compliance review of contracts, specifically including the following functions: 1. Intelligent Contract Template Management: The system has a built-in standard contract template library for major commodities (non-ferrous metals, ferrous metals, energy and chemicals, agricultural products, etc.), covering various types such as purchase contracts, sales contracts, agency contracts, warehousing contracts, and pledge contracts; the template terms support dynamic configuration by commodity and transaction mode (spot / futures-to-spot / point-of-price contracts, etc.); 2. Automatic data filling in transactions: After the contract is confirmed, the system automatically extracts key elements (variety, specifications, quantity, unit price, total price, delivery location, delivery method, payment terms, quality inspection standards) from the transaction database and fills them into the corresponding contract template fields, achieving 100% completeness and eliminating manual input errors. 3. AI-powered Intelligent Contract Clause Review: The system utilizes a large AI model to perform deep semantic analysis of contract texts, scanning for risks from the following dimensions: compliance review (whether the clauses comply with relevant laws and regulations); identification of abnormal clauses (whether the pricing method conforms to industry practices, whether the penalty ratio is abnormal, and whether the quality inspection clauses are complete); missing item check (whether necessary clauses are complete); consistency verification (whether the varieties, quantities, and prices in the contract text are consistent with the transaction system records); the review results are presented as a risk score (0-100 points) and a list of specific risk warnings, with high-risk clauses highlighted in red and modification suggestions provided; 4. Contract Version Management: The system records the complete modification history of the contract. Each modification generates a new version and marks the modifier, modification time, and a summary of the modification content. Both the buyer and seller can view the complete version change record, ensuring that the contract negotiation process is transparent and traceable.

[0030] II. Multi-party electronic signature collaboration module, enabling online collaborative signing by multiple entities, specifically including the following functions: 1. National Cryptographic Level Identity Authentication and Signature: The system integrates a CA certificate system that conforms to national cryptographic standards. Enterprise users can apply for electronic signature certificates after completing real-name authentication through their business license and legal representative information. The signature operation uses the SM2 asymmetric encryption algorithm to generate digital signatures, and the SM2 hash algorithm ensures the integrity of the signature content, meeting the legal validity requirements of the Electronic Signature Law. 2. Multi-party signing process orchestration: The system supports flexible configuration of multi-party signing processes, including sequential signing (the buyer signs first and then sends it to the seller), parallel signing (multiple parties sign simultaneously), and condition-triggered signing (such as the guarantor's signing must be triggered after both the buyer and seller have completed their signing); signing invitations are pushed synchronously through three channels: in-system messages, SMS, and email. 3. Real-time tracking of signing progress: The system generates a signing status dashboard for each contract, displaying the signing status of all parties in real time (pending signing / signed / rejected), signing timestamp, and signing device information; a signing timeout reminder mechanism is set up, which automatically pushes a reminder to the non-signing party when there are 24 hours / 2 hours left before the deadline; 4. Handling of Refusal and Objections: If either party refuses to sign, they must fill in the reason for refusal in the system. The system will simultaneously notify the other signatories of the reason for refusal. Both the buyer and seller can initiate contract modification negotiations in the system. The modified version will re-enter the signing process, and the entire process will be recorded. 5. Cross-platform signing support: Supports three signing entry points: Qt desktop (PC client), Flutter mobile (iOS / Android) and web browser, ensuring that users on different devices can easily complete the signing operation and have a consistent signing experience.

[0031] III. Blockchain Contract Storage and Supervision Interface Module, used to ensure the long-term legal validity of electronic contracts and compliance with regulations, specifically implements the following functions: 1. Contract hash on-chain notarization: After all parties have signed the contract, the system calculates the SHA-256 hash value of the contract PDF file and uploads the hash value, signing completion timestamp, certificate serial number of each signatory and other metadata to a trusted blockchain node for notarization; after notarization is completed, a unique notarization number and blockchain transaction hash are returned and written to the contract details page; 2. Real-time Contract Integrity Verification: At any time, users or regulators can initiate contract integrity verification through the system: The system recalculates the SHA-256 hash value of the current contract file and compares it with the hash value stored on the blockchain. If they are completely consistent, the system outputs that the verification is successful (the contract content has not been tampered with); if they are inconsistent, the system outputs a tampering alarm and locks the contract status. 3. Reserved Regulatory Interface: The system reserves a data interface for regulatory agencies, allowing regulators to query the signing records, evidence storage information, and performance status of designated contracts under authorized conditions; it also supports the periodic export of compliance reports as required by regulations. 4. Long-term contract archiving management: The system archives completed contracts in a structured manner, supporting fast retrieval by multiple dimensions such as contract number, signing date, product type, counterparty, and contract status; archived data is stored in encrypted form and retained for no less than 20 years.

[0032] IV. Digital delivery code and anti-counterfeiting verification module, used to replace traditional paper delivery slips, realize the digitalization and anti-counterfeiting of delivery vouchers, specifically including the following functions: 1. Dynamic Pickup Code Generation: After the contract is signed and payment is confirmed, the system automatically generates a unique digital pickup code. The pickup code consists of a 32-character random string and is strictly bound to the contract number, product type, quantity, validity period, and designated pickup warehouse. The pickup code is stored in an encrypted manner and can only be viewed by the contract buyer. 2. Management of Pickup Code Validity and Usage: The default validity period of the pickup code is the pickup time window agreed in the contract, and it will automatically expire after the expiration date; the pickup code is for one-time use, and it is marked as used once the verification is successful, eliminating the risk of multiple pickups with one code; if you need to pick up goods in batches, the system supports splitting and generating multiple sub-pickup codes, each of which corresponds to an independent quantity and validity period; 3. Warehouse-side barcode scanning verification: Warehouse administrators scan the pickup code using the system's mobile terminal (Flutter application) or a dedicated barcode scanning device. The system verifies the validity, type, quantity, and identity of the pickup code in real time. Once verification is successful, the system will immediately link with the WMS to generate an outbound instruction. 4. Complete record keeping for pickup: The system records a complete operation log for pickup verification, including key information such as verification time (accurate to the second), verification location (GPS coordinates), operator number, quantity issued, and photos of the goods' appearance (uploaded by warehouse staff), forming a complete digital evidence chain for pickup.

[0033] V. Intelligent Logistics End-to-End Tracking Module: Enables fully visualized tracking of goods from warehouse to buyer's receipt, specifically implementing the following functions: 1. Multi-logistics platform API integration: The system integrates the API interfaces of major logistics service providers, supporting real-time retrieval of data such as waybill status, vehicle GPS location, and estimated time of arrival (ETA); 2. Full lifecycle management of goods status: The system defines a standardized goods flow status chain: contract signing completed → payment received and confirmed → pickup code generated → warehouse preparation → awaiting pickup / shipment → in transit → arrived → buyer's signature confirmation → delivery completed; each status change is recorded with a timestamp, and both the buyer and seller can view it in real time through the App / PC. 3. AI Logistics Anomaly Warning: The system establishes a normal logistics timeliness benchmark model based on historical logistics data. When the actual transportation time exceeds 120% of the benchmark timeliness, a delay warning is triggered and pushed to both the buyer and seller. When the system detects that the waybill status has not been updated for a long time (no status change for more than 6 hours), it automatically initiates a logistics provider query request. 4. Online quality inspection results: When the buyer receives the goods, they can upload the quality inspection report (PDF format) issued by a third-party quality inspection agency into the system. The system will use OCR technology to automatically extract the key indicators in the quality inspection report and automatically compare them with the quality standards agreed in the contract. If the test value exceeds the range allowed by the contract, the system will automatically mark it as a quality objection status.

[0034] VI. The integrated futures and spot delivery module breaks down the system barriers between physical delivery of futures contracts and physical logistics and pickup of spot goods, specifically achieving the following functions: 1. Automatic matching of futures warehouse receipts and spot contracts: The system automatically matches the physical delivery warehouse receipts (including commodity, quantity, delivery warehouse, and warehouse receipt number) in the futures position with the spot purchase contract; after successful matching, the system prompts the operator for confirmation, and after confirmation, the futures warehouse receipt cancellation process and the spot delivery process are started simultaneously; 2. Warehouse WMS Linkage: The system establishes a data interface with the WMS systems of major futures delivery warehouses to obtain real-time information on warehouse receipt cancellation progress, actual cargo release time, and release quantity; after the futures warehouse receipt cancellation is completed, the system automatically updates the cargo status of the spot contract and generates the corresponding spot delivery code. 3. Payment and delivery settlement linked: The system supports configuring automatic triggering conditions for payment settlement, such as: buyer's signature confirmation and quality inspection results meeting the agreement → automatically triggering payment settlement instruction → notifying the financial system to initiate bank transfer; 4. Delivery Completion Report: After the entire futures and spot delivery process is completed, the system automatically generates a complete delivery report, which includes: basic contract information, completion time nodes of each stage, goods inspection results, delivery records, payment settlement status and blockchain evidence number. The report is generated in PDF format and simultaneously pushed to both the buyer and seller and relevant regulators.

[0035] Another embodiment of the present invention relates to a method for futures-spot integrated electronic contract management and intelligent logistics delivery, comprising the following steps: 1. System Initialization: Load system configuration: contract template library (categorized by product and type), signatory company information and electronic signature certificates, blockchain node interface configuration, logistics platform API key, associated warehouse WMS interface configuration, and AI contract review model parameters; at the same time, complete the data interface integration with the futures and spot trading system to ensure that transaction data can trigger the contract generation process in real time.

[0036] 2. Spot Transaction Confirmation and Automatic Contract Generation: When a spot transaction is matched in the spot-futures integrated trading system or both parties click to confirm the transaction, the system pushes a transaction data package (product code, specifications, quantity, unit price, buyer ID, seller ID, delivery method, and payment method) to the contract management module. The contract management module automatically matches a contract template based on the product type and delivery method, and automatically fills the key elements in the transaction data package into the corresponding fields of the contract template. The system generates a contract draft (PDF preview) and pushes it to both the buyer and seller for confirmation.

[0037] 3. For example Figure 2 As shown, the AI ​​contract intelligent review module automatically executes the following review process after the contract draft is generated: Regulatory compliance check: Access the compliance rule database to verify whether the contract terms contain any content that violates laws and regulations, with a focus on pricing terms, penalty clauses, and quality inspection clauses; AI-powered identification of unusual clauses: The AI ​​model performs semantic understanding of the entire contract and identifies clauses that deviate significantly from industry practices, such as: abnormal payment ratios (prepayment ratio greater than 90% or zero prepayment), overly lenient quality standards, and excessively short delivery periods. Field consistency check: The system automatically compares the variety, quantity, unit price, and total price in the contract text with the transaction records in the trading system. If any values ​​are inconsistent, they are marked as data consistency anomalies and manual review is required. Review results output: Generate a contract review report, including a risk score (0-100 points, above 80 points is low risk, 60-80 points is medium risk, and below 60 points is high risk), a list of risk clauses and modification suggestions; high-risk contracts must be manually approved by risk control personnel before entering the signing process.

[0038] 4. Multi-party electronic signature collaborative signing. After the contract passes review, it enters the signing process: Signatory Confirmation: The system confirms the parties required to sign this contract (at least the buyer and seller, and may also include the guarantor, supervisor, etc.) based on the contract type and configuration rules. Signing invitation push: The system simultaneously pushes signing invitations to all signatories through three channels: in-system messages, SMS, and email; Authentication and Signature Execution: The signatory completes enterprise authentication (CA certificate verification) through the system. After confirming that the contract content is correct, the signatory clicks on the electronic signature. The system calls the SM2 algorithm to digitally sign the [contract PDF hash value + signatory certificate serial number + signing timestamp], and the signature data is appended to the digital signature field of the contract PDF. Real-time synchronization of signing status: Once one party completes signing, the system updates the signing status dashboard in real time and pushes progress notifications to other signatories; Signature Completion Confirmation: After all signatories have completed signing, the system locks the contract content, generates a final contract PDF containing the digital signatures of all signatories, and triggers the blockchain notarization process.

[0039] 5. For example Figure 3 As shown, the blockchain contract is stored. After the final contract PDF is generated, the system performs the storage operation: Calculate the SHA-256 hash value of the contract: H_contract = SHA256 (binary content of the contract PDF); Construct the evidence storage data package: {Contract No., H_contract, Signing Completion Timestamp, List of CA Certificate Serial Numbers of Each Signatory, Contract Type, Variety Code, Quantity, Amount}; Upload the evidence storage data package to a trusted blockchain node to obtain the blockchain transaction hash TxHash and block height BlockHeight; Write {TxHash, BlockHeight, Evidence Preservation Time} into the contract details database and automatically append an evidence preservation certificate page to the last page of the contract PDF; Once the notarization is completed, the system will send a notification to all signatories that the contract notarization was successful.

[0040] 6. For example Figure 4 As shown, the system confirms payment and generates a pickup code. After the buyer completes payment, the system performs the following operations: The financial system interface verifies the payment receipt information (amount, payer, and receipt time) and automatically compares it with the payment terms stipulated in the contract. When the amount received matches the contract amount (or meets the down payment ratio requirement), the system automatically generates a digital pickup code; Pickup code binding parameters: contract number, product type, quantity (can be split into multiple sub-pickup codes), valid pickup time window, designated pickup warehouse, buyer company ID; The pickup code is stored in encrypted form and can only be viewed by the buyer's verified account. The system will also push a pickup notification to the buyer's App. For installment payment contracts, the system generates a sub-pickup code for the corresponding batch after each payment is confirmed.

[0041] 7. For example Figure 5 As shown, the system confirms warehouse stock preparation and outbound shipments. The system then synchronizes the pickup information to the corresponding warehouse's WMS system. After WMS receives the delivery order, the warehouse dispatcher begins preparing the goods (picking, weighing, and packing). After the goods are prepared, the warehouse staff will update the status to "pending pickup" on the mobile app and upload photos of the goods (at least 3 photos, which will be automatically timestamped and GPS watermarked by the system). The system sends a notification to the buyer that the goods preparation is complete; When the buyer picks up the goods, warehouse staff scan the pick-up code using the system's mobile terminal, and the system verifies the validity of the pick-up code and the buyer's identity in real time; After verification, WMS generates an outbound order. The system records the outbound time (accurate to the second), the operator's employee number, and the actual outbound weight of the goods (compared with the quantity agreed in the contract; if the deviation is greater than 0.5%, the system marks it as abnormal). Once the goods are shipped out, the pickup code will automatically become invalid, and the contracted goods status will be updated to "shipped out".

[0042] 8. Logistics Tracking and Anomaly Warning. Goods enter the logistics tracking stage after leaving the warehouse: If the buyer entrusts a logistics provider for transportation, the system receives the waybill information through the logistics API, retrieves the waybill status update every 10 minutes, and displays the GPS location and transportation progress in real time on the map on the order details page of both the buyer and seller; The system calculates the normal delivery time benchmark T_baseline for the current route based on historical logistics data. If the actual transportation time exceeds T_baseline × 1.2, a delay warning is triggered. If the status of the waybill has not been updated for more than 6 hours, the system will automatically send a status query request to the logistics provider and push a notification to both parties. After the goods arrive at the buyer's designated location, the buyer can perform a receipt confirmation operation in the system and simultaneously upload photos of the goods and preliminary quality inspection notes.

[0043] 9. Quality Inspection Result Sharing and Objection Handling. After completing the quality inspection, the buyer uploads the third-party quality inspection report to the system. The system calls the OCR recognition engine to extract key fields from the quality inspection report (name of the testing institution, testing date, sample number, various quality indicators and test values); The AI ​​model will automatically compare the extracted quality indicators with the quality standards agreed in the contract, and determine whether each indicator meets the standards. If all indicators are within the contractually permissible range, the system will automatically confirm that the quality is up to standard, update the contract status to "quality inspection passed," and trigger the final payment settlement process. If any indicator exceeds the scope allowed by the contract, the system will automatically trigger the quality objection process: mark the contract status as a quality objection, push the objection details to the seller, and both parties can negotiate the objection within the system; the system saves the complete quality inspection report and AI comparison results as digital evidence for dispute resolution.

[0044] 10. Integrated processing of futures and spot delivery. For spot contracts involving physical delivery of futures contracts, the system executes the following linked operations: The trading system pushes futures warehouse receipt information (warehouse receipt number, commodity, quantity, and delivery warehouse) to this system, and the system automatically matches the corresponding spot purchase contract; The operator confirms the matching relationship between futures warehouse receipts and spot contracts within the system; The system simultaneously sends a warehouse receipt cancellation application to the futures company's counter system and sends a delivery instruction to the WMS; 10.4 After the futures warehouse receipt cancellation is completed, the system automatically generates a delivery code for the corresponding spot contract; The subsequent pickup, logistics, quality inspection and settlement processes are consistent with the standard spot goods process; Once the entire process is completed, the system generates a complete futures and spot delivery report, which is automatically pushed to the buyer, seller, futures company, and regulatory interface.

[0045] 11. Delivery Completion and Archiving. After all processes are completed, the system performs the following closing operations: the contract status is updated to "Completed"; a delivery completion report (PDF format) containing the entire operation record is generated; all relevant documents (original contract, proof of delivery, delivery record, quality inspection report, logistics record) are packaged and archived to an encrypted storage system; the archived documents are retained for no less than 20 years.
