Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a blockchain-based logistics management method, device and electronic equipment. Background Art

[0002] With the rapid development of Internet technology, the logistics industry, as an indispensable bridge connecting production and consumption, has become the focus of attention both inside and outside the industry in terms of its operational efficiency and data security.

[0003] Traditional logistics management systems are limited by a centralized architecture. This model has significant obstacles in promoting information sharing among various participants (such as manufacturers, carriers, distributors and consumers), forming information islands and seriously restricting the smoothness and efficiency of logistics processes. In terms of data security, traditional systems are often the target of cyber attacks. Once their centrally stored databases are invaded, sensitive logistics information may be leaked or maliciously tampered with, which not only harms corporate interests but also poses a threat to consumer privacy. In addition, due to the lack of an effective traceability mechanism, traditional logistics management systems are unable to track and trace goods. When delays, damage or loss occur during the logistics process, it is difficult to quickly and accurately locate the responsible party, which increases the complexity and time cost of dispute resolution.

[0079] Figure 1 A schematic diagram of the principle of a blockchain-based logistics control method provided in an embodiment of this specification, the method may include:

[0080] S110: The transaction request node publishes the logistics transaction information to the blockchain logistics management and control platform;

[0081] In the specific implementation of this specification, the transaction information includes commodity information, consignee and consignor information, transportation method, etc., and also includes the identification information of the regulatory agency directly involved in the review of the transaction.

[0082] S120: The technical compliance node and the business compliance node respectively conduct compliance review on the logistics transaction information through the blockchain logistics management and control platform;

[0083] In the specific implementation of this specification, the regulatory agency (e.g., bank) node designated by the exchange will be responsible for receiving and carefully reviewing the transaction. If the transaction successfully passes the review process, the transaction will be securely forwarded to the consensus node for subsequent processing; on the contrary, if the transaction fails to meet the review standards, a rigorous regulatory processing mechanism will be immediately triggered to ensure the compliance and security of the trading environment.

[0084] S130: When all audits are in compliance, a preset number of candidate consensus nodes are selected as actual consensus nodes based on the blockchain logistics management and control platform, and the actual consensus nodes perform transaction consensus verification on the logistics transaction information through the blockchain logistics management and control platform;

[0085] Optionally, the S130 includes:

[0086] Determine the reputation value of the candidate consensus node based on the comprehensive consensus reputation value, smart contract performance reputation value, and freight volume reputation value of the candidate consensus node;

[0087] A preset number of candidate consensus nodes are selected as the actual consensus nodes based on the candidate consensus node reputation values.

[0088] In the specific implementation of this specification, the workflow of the regulatory node specifically includes the following three core steps: First, the regulatory node will accurately obtain regulatory indicators that match the established regulatory rules. These indicators are the benchmark for the audit work; then, the node will deeply identify various regulatory factors in the original transaction information to ensure that there are no omissions; finally, the actual value of the regulatory factor is carefully compared with the threshold set by the regulatory indicator, and based on the comparison results, the corresponding regulatory processing mechanism is decisively and accurately executed.

[0089] The content of the regulatory review is comprehensive and in-depth, covering multiple key dimensions: 1) Account review: This link requires the node to actively submit its blockchain address to the regulatory node. The regulatory node can quickly locate and verify the corresponding account information with the address to ensure the authenticity and compliance of the account. 2) Transaction content security and privacy review: In this step, the regulatory node will strictly review the transaction information to ensure that it does not contain any Trojans or virus programs that may pose a threat to the security of blockchain information, and at the same time check whether there is sensitive information that leaks personal privacy to ensure the security of the transaction environment and the privacy rights of users. 3) Transaction content legality review: The regulatory node will carefully judge the legality of the transaction information, including but not limited to whether the transaction goods belong to the category of contraband, and whether the transportation methods, warehousing, packaging, handling and other links involved in the transaction comply with the provisions and requirements of relevant laws and regulations to ensure that every link of the transaction is legal and compliant. 4) Transaction content compliance review: In addition, the regulatory node will also carefully evaluate the compliance of the transaction content, such as the accurate classification of products and the compliance of letters of credit, to ensure that the transaction behavior complies with industry norms and regulatory requirements.

[0090] It is worth noting that according to the specific needs of the audit tasks and the differences in supervision intensity, the audit content of the supervision node can be flexibly adjusted. It can not only comprehensively cover all the above dimensions, but also selectively include one or more of the audit contents according to specific needs, so as to achieve efficient and accurate supervision.

[0091] Optionally, determining the comprehensive consensus reputation value of the candidate consensus node includes:

[0092] Based on the historical node reputation value and the node reputation value of the most recent consensus cycle of the candidate consensus node, the comprehensive consensus reputation value of the candidate consensus node is determined.

[0093] Optionally, the process of determining the historical node reputation value of the candidate consensus node and the node reputation value of the candidate consensus node in the most recent consensus cycle includes:

[0094] The process of determining the historical node reputation value of the candidate consensus node specifically includes:

[0095]

[0096] in, is the historical node reputation value of the candidate consensus node, T is the current consensus cycle, They represent the total number of malicious votes and the total number of good faith votes of node i (i=1,2,…n) participating in the consensus verification process from joining the blockchain logistics control platform to the Tth consensus cycle, h is the historical performance, and β≥1 is the reputation coefficient of the historical consensus performance of the candidate consensus node;

[0097] The process of determining the node reputation value of the candidate consensus node in the most recent consensus cycle specifically includes:

[0098]

[0099] in, is the node reputation value of the candidate consensus node in the most recent consensus cycle, It represents the number of malicious votes and good faith votes of node i in the consensus process in the previous consensus cycle T-1, and ω≥1 is the penalty factor.

[0100] In a specific implementation of the present specification, the system adjusts the reputation coefficient at any time according to the size of the node reputation value, that is, it decreases as the node reputation value increases, so as to avoid the node reputation value growing too fast.

[0101] ω≥1 is the penalty factor. The larger its value is, the less tolerant the system is to malicious voting.

[0102] Optionally, determining the comprehensive consensus reputation value of the candidate consensus node based on the historical node reputation value and the node reputation value of the most recent consensus cycle of the candidate consensus node includes:

[0103]

[0104] in, is the comprehensive consensus reputation value of the candidate consensus node, and It is divided into weight coefficients representing the reputation value of historical nodes and the reputation value of nodes in the most recent consensus cycle.

[0105] In a specific implementation of this specification, the process of determining the smart contract performance reputation value of the candidate consensus node includes:

[0106]

[0107] in, is the smart contract performance reputation value of the candidate consensus node, q ′ , It represents the number of times the smart contract has been fulfilled normally and the number of times it has defaulted since node i joined the blockchain logistics management and control platform to the Tth consensus cycle. is the total number of smart contracts that node i has executed, and δ≥1 represents the system's reward coefficient for normal performance. The system adjusts the reward coefficient at any time based on the node's reputation value, that is, it decreases as the node's reputation value increases. Once a smart contract is deployed, it cannot be modified. Therefore, for nodes that have completed performance normally, the node reputation value is calculated mainly in a reward-based manner.

[0108] The process of determining the freight volume reputation value of the candidate consensus node includes:

[0109]

[0110] in, is the freight volume reputation value of the candidate consensus node, σ is the reputation value conversion factor of the historical cumulative freight volume, is the historical cumulative freight volume of node i.

[0111] The process of determining the reputation value of a candidate consensus node includes:

[0112]

[0113] in, is the reputation value of the candidate consensus node, l1, l2, l3 are the weight factors of the comprehensive consensus reputation value, smart contract performance reputation value, and freight volume reputation value, and l1+l2+l3=1. l4 is the number of times that node i has been found to be incorrect in the signature verification process when it packages non-compliant or illegal transactions into blocks and broadcasts them to the entire network during the consensus process from the time when node i joined the blockchain logistics control platform to the Tth consensus cycle. γ≥1 is the penalty factor set by the system. The larger γ is, the less tolerance the system has for non-compliant or illegal transactions on the chain. In order to consider the reputation loss mechanism of business compliance, when a node participates in non-compliant or illegal transactions on the chain, its reputation value will be greatly reduced. This increases the cost of nodes doing evil, ensures the compliance and legality of on-chain transactions, and maintains the stable operation of the blockchain system. The weight factor can be adjusted at any time according to the business type and system status. By adjusting the reputation weight factor, different types of nodes can have the opportunity to participate in the blockchain consensus, that is, the emphasis is placed on the consensus performance of the node, the accumulated business volume, or the performance of the node. At the same time, the system sets the maximum value of the node reputation value. When the node reputation value grows to the maximum value, the node reputation value will no longer grow. The reputation value growth in this consensus mechanism is nonlinear. The higher the reputation value, the slower the growth rate, to avoid the situation where the node reputation value is too high and affects the decentralization of the blockchain.

[0114] S140: When the transaction consensus verification is passed, the block packaging node packages the logistics transaction information with other logistics transaction information within the preset time interval to generate block information, and broadcasts it to the actual consensus node through the blockchain logistics management and control platform;

[0115] S150: The actual consensus node performs block consensus verification on the block information through the blockchain logistics management and control platform;

[0116] In the specific implementation of this specification, the determined consensus nodes pay certain consensus resources to participate in consensus verification, where consensus verification includes transaction verification, digital signature of the transaction after successful verification, and sending the verification success message to other consensus nodes. Consensus resources refer to the combination of node computing resources (resource consumption such as encryption and decryption, protocol parsing, etc.), network resources (such as broadband and traffic resources), storage resources (such as hard disk or memory resources) and equity resources.

[0117] S160: When the block consensus verification is passed, the logistics transaction information is put on-chain for management and control.

[0118] Optionally, the transaction consensus verification is achieved by including a preset proportion of the actual consensus nodes agreeing to put the logistics transaction information on the chain.

[0119] Optionally, the preset proportion of the actual consensus nodes agreeing to upload the logistics transaction information to the chain includes:

[0120] The consensus verification algorithm includes a Byzantine fault-tolerant consensus algorithm;

[0121] The preset proportion of the actual consensus nodes agrees to put the logistics transaction information on the chain, specifically:

[0122] N ≥ 3f + 1

[0123] Wherein, N is the total number of nodes in the network, and f is the actual consensus node agreed upon.

[0124] In the present invention, the compliance of information is ensured through the dual review of technical compliance and business compliance, and the immutability of blockchain technology strengthens the security of data. The automated processing of smart contracts and the dynamic node selection mechanism (based on the comprehensive consensus reputation value, smart contract performance reputation value and freight volume reputation value) not only speed up the transaction process, but also enhance the stability and reliability of the blockchain network. In addition, the Byzantine fault-tolerant consensus algorithm and the consensus node consent mechanism with a preset ratio further enhance the fault tolerance of the system and ensure stable operation in complex environments. At the same time, the data traceability and auditability on the blockchain provide the logistics industry with powerful supervision and dispute resolution capabilities.
