Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
The cross-chain logistics business management method, device and electronic equipment of the present invention are described below with reference to fig. 1 to 6.
The cross-chain logistics business management method provided by the embodiment of the invention can be applied to the block chain link point corresponding to the source block chain corresponding to the business order management mechanism. The block link point corresponding to the source block chain corresponding to the service order management mechanism may be a server or a processor, and may be disposed in a virtual network device or a physical network device. The nodes corresponding to different blockchains may be disposed on different servers.
The block chain is a chain composed of a plurality of blocks. Each block holds certain information, which are linked in a chain according to a respective generated time sequence. This chain is maintained in all servers, and as long as one server can work in the entire system, the entire blockchain is secure. In this case, the servers act as blockchain nodes in the blockchain system, which provide storage space and computational support for the entire blockchain system.
If the information in the block chain is to be modified, more than a certain number of nodes must be agreed and the information in all the nodes must be modified, and the nodes are usually held in different subjects, so that the information in the block chain is extremely difficult to tamper with. Compared with the traditional network, the block chain has two core characteristics: firstly, data is difficult to tamper, and secondly, centralization is carried out.
On this basis, the blockchain becomes a novel application mode of computer technologies including distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like, and is essentially a decentralized database. The block chain can be composed of a plurality of series transaction records (also called blocks) which are connected in series by cryptography and protect the contents, and the distributed accounts connected in series by the block chain can effectively record the transaction by multiple parties and permanently check the transaction.
The cross-chain logistics service management method provided by the embodiment of the invention is based on a block chain technology, is applied to a block chain node corresponding to a source block chain corresponding to a service order management mechanism, and can simultaneously perform cross-chain operation on a plurality of sub-block chains based on the source block chain.
In some embodiments, the sub-block chain includes at least one of a first sub-block chain corresponding to a logistics transportation and supervision organization, a second sub-block chain corresponding to a financial management organization, and a third sub-block chain corresponding to a logistics warehouse management organization, so that an effect that a source chain automatically sends information to a sub-chain in a cross-chain operation to reduce network load is achieved.
It can be understood that in the field of logistics management, especially in the field of cold-chain logistics management, the source block chain corresponding to the business order management authority, the first sub-block chain corresponding to the logistics transportation and supervision authority, the second sub-block chain corresponding to the financial management authority, and the third sub-block chain corresponding to the logistics warehouse management authority may be included.
As shown in fig. 1, the method for managing logistics service across chains in the embodiment of the present invention mainly includes step 110 and step 120.
It will be appreciated that the information query request is determined based on the information query input to the business order by the target object. And the service mechanism corresponding to the sub-block chain is associated with the service order management mechanism of the source block chain in the logistics service. The business order management mechanism can correspond to the source block chain, the logistics transportation and supervision mechanism can correspond to the first sub-block chain, the financial management mechanism can correspond to the second sub-block chain, and the logistics warehouse management mechanism can correspond to the third sub-block chain.
The target object can be a person of a business order management organization, and the target object can inquire and manage signing information, logistics transportation and supervision information, financial information and logistics warehouse information of a business order.
The order information may include time of order, party, specific logistics transportation item, transportation time, and transportation contract of the business order, and the like. The logistics transportation and supervision information can comprise the selection of logistics parties, logistics modes, logistics paths, logistics process supervision contents and the like. The financial information may include revenue, expenditure, deductions, and rewards for each of the transactions of the order. The logistics warehouse information may include information regarding the warehouse storage of items to be shipped in various links.
The target object can realize the information inquiry input of the service order through the terminal equipment or other equipment.
Various information types of the business orders to be inquired by the target object are not limited, and the input mode of the information inquiry request is not limited.
In this embodiment, the information query request is sent to each other module corresponding to the logistics service through the source block chain corresponding to the service order management mechanism, and the source block chain can directly initiate information transfer to each sub-block chain.
And step 120, receiving the query feedback information sent by the second blockchain node.
It can be understood that after receiving the query request sent by the first block chain node corresponding to the source block chain, the second block chain node corresponding to the sub-block chain can send query feedback information to the first block chain node corresponding to the source block chain according to the corresponding intelligent contract, which is convenient for the target object to determine the queried content.
It should be noted that each sub-chunk chain may implement its respective function based on the corresponding intelligent contract.
For example, the functions of data collection, data judgment, early warning processing, event transmission, event reception, tracing verification and the like can be realized by the second block link point corresponding to the first block chain corresponding to the logistics transportation and supervision mechanism, and the functions of each block chain are not limited herein.
In this embodiment, the sub-block chain may generate first metadata corresponding to the first block link node sending the information query request, and send query feedback information to the first block link node, where the first metadata is used to indicate that the source block chain has performed information query on the sub-block chain.
It should be noted that the metadata can effectively help technicians and service personnel to understand, supervise and manage information such as data sources, conversion rules, data change management and the like for descriptive information of data flow direction and information resources in the cross-link operation, thereby improving the working efficiency.
In this embodiment, by determining the first metadata, the information query request of the source block chain can be conveniently recorded, and the first metadata is actively used for performing uplink certificate storage on the sub-block chain, so that the certificate storage of the data is realized.
According to the cross-chain logistics service management method provided by the embodiment of the invention, the transmission and information query request is actively initiated to the sub-block chain through the source block chain, so that cross-chain information interaction of the source block chain is realized, the sub-block chain is not required to continuously send event information to the source block chain in a passive polling mode, and data is only sent to the source chain under the condition that the source chain has the information transmission requirement to the corresponding sub-chain, so that the data transmission quantity and the required computing capacity are reduced, and the network burden and the transmission cost in the cross-chain transmission process are reduced.
In the embodiment of the present invention, as shown in fig. 2, an active multiplexing method can help one source block chain to simultaneously call multiple different service sub-chains, and multiple different sub-chains can simultaneously initiate call-back to a main chain, which is different from a traditional passive event monitoring method based on polling, thereby greatly reducing communication cost.
The block chain link points of the sub-block chain can generate a section of data packet to be sent, namely query feedback information, according to the query result hash value and the time stamp encrypted by the private key, and the digital signature of the data packet is the content encrypted by the private key.
And calculating the abstract of the data packet by using the hash algorithm with the same encryption process at the block chain node of the source block chain for receiving the query feedback information, encrypting the abstract by using the public key of the second block chain node of the sub-block chain, decrypting the digital signature, and comparing the two to realize signature verification.
In the embodiment, the query result is encrypted, so that the safety in the data transmission process can be ensured, the first metadata comprises the hash value of the query result, the timestamp for sending the information query request to the second block link node by the source block chain is also included, all information of the cross-chain operation can be recorded, and the tracing and the auditing of the whole-chain node are ensured.
Taking temperature query in the cold chain logistics supervision process as an example, the target object may send a temperature information query request to a first block link point of a first sub-block chain corresponding to the logistics transportation and supervision authority according to an intelligent contract of the source block chain.
The intelligent contract corresponding to the first block link point of the first sub-block chain can regularly send a supervision request to the temperature sensor equipment in the cold-chain logistics transport vehicle, and the temperature sensor equipment collects environmental data after receiving the request, uploads the temperature data to the block chain platform through the node corresponding to the data collection function, and stores the temperature data in the first sub-block chain.
The data judgment corresponding to the block link point in the first sub-block chain compares the collected data with a corresponding reasonable temperature threshold set by the system. And if the result is in a reasonable range, signing the processed data and the node corresponding to the result through traceability verification, transmitting the signed data and the node corresponding to the data uplink into a file system, and performing hash value uplink on the data to realize the traceability of the data.
If the result is not within the reasonable range of values, the data is linked up by extracting the hash value after the batch of products is marked as temperature anomaly while the file system stores the data. And finally, the node corresponding to the early warning processing can early warn the relevant processing node through an early warning function to inform the relevant processing node to process the data abnormity.
After the processing, the first sub-block chain may send the processing result to a source block chain corresponding to the business order management organization for filing, and the source block chain synchronizes the related data to a second sub-block chain corresponding to the financial management organization, so that the second sub-block chain performs related operations according to the corresponding intelligent contract.
According to the early warning condition, the second sub-block chain can deduct the guarantee fund of the specified quantity of the corresponding responsible nodes according to the intelligent contract, wherein each time of chain crossing operation can generate a signature and a related data block for chain linking, and the source tracing and the auditing of the full-chain nodes are guaranteed.
In some embodiments, before sending the information query request to the second block link node corresponding to the sub-block chain, the method for managing logistics services across chains in an embodiment of the present invention further includes: and under the condition of determining the sign of the service order, packaging the data required by the sub-block chain corresponding to the service order, extracting the hash value of the service order data from the data required by the sub-block chain corresponding to the service order, and generating a data packet corresponding to the service order after digital signature.
It can be understood that for each uplink service order, the service order will be placed in the source block chain.
Of course, the source blockchain initializes the address and key information of each node of the organization in a cross-chain environment prior to order sign-in. Then, after the order service is signed and linked, the order management chain node distributes contracts to each sub-chain and stores the invoked metadata.
In this case, second metadata for transmitting a data packet corresponding to the service order to the second block link point corresponding to the service order is generated.
The data packet corresponding to the service order can be signing information, logistics transportation and supervision information, financial information, logistics warehouse information and the like of the service order.
After each sub-block link receives the data packet corresponding to the service order, each piece of information can be updated according to the respective corresponding intelligent contract.
And the second metadata is used for indicating that the block link point corresponding to the source block chain sends the data packet corresponding to the service order to the second block link point corresponding to the service order.
In some embodiments, the second metadata may be determined in the following manner.
It is to be understood that the second blockchain node corresponding to the service order may be determined based on the intelligent contract corresponding to the source blockchain, that is, the second blockchain node of the subblockchain corresponding to the service order is determined from a plurality of nodes of the plurality of subblockchains.
In this case, the second metadata is determined based on the timestamp of sending the data packet corresponding to the service order to the second block link point corresponding to the service order and the hash value of the service order data. The service order data hash value may be set at the end of the data packet.
It is to be understood that the second metadata includes IP addresses of nodes corresponding to the data sender and the data receiver.
In this embodiment, the second metadata includes a timestamp for sending data from the source block chain to the sub-block chain and a hash value of the service order data, so that accuracy, security, and traceability of a data packet corresponding to the service order are ensured.
In this case, the second metadata uplink is stored, and the data packet corresponding to the service order is sent to the second block link point.
In this embodiment, the source blockchain actively sends a data packet to each subchain, so that automatic sending of relevant data required by the subchain is realized, a request of the subchain is also not required, and the success of calling is confirmed by using a callback function after the subchain receives information and successfully verifies the information.
In some embodiments, after sending the data packet corresponding to the service order to the second block link point corresponding to the service order, the method for managing logistics services across chains according to the embodiments of the present invention further includes verifying the received data.
In this embodiment, the second block link point corresponding to the service order may perform signature verification and integrity verification on the hash value of the service order data in the data packet corresponding to the service order.
And calculating the abstract of the data packet by using a Hash algorithm with the same encryption process at the block chain link points of the source block chain, encrypting the abstract by using the public key of the second block chain link point through the client corresponding to the second block chain link point, decrypting the digital signature, and comparing the two to realize signature verification.
Under the condition, the integrity verification is continuously carried out on the service order data hash value, and under the condition that the signature verification and the integrity verification pass, the data packet corresponding to the service order is stored in an uplink manner, so that the integrity and the safety of the data received by the sub-chain are ensured.
In the verification of the received data, a joint verification mode is adopted, namely, the transmission node self-verifies the integrity and the anti-counterfeiting performance of the data by utilizing a hash mechanism and a signature mechanism, and other verification nodes verify the correctness of the hash value through corresponding organization node request source block chain nodes.
Meanwhile, the one-to-many cross-link communication model reduces the storage pressure, solves the problem that the traditional single-machine multi-link operation memory occupies, and performs business data classification management.
After the data packet is uplinked, if the other sub-blockchain nodes want to perform verification of authenticity or operation, the other sub-blockchain nodes can perform cross-chain verification with the corresponding source blockchain node.
In the cross-link logistics service management method of the embodiment of the invention, an active multiplex cross-link calling method service model is adopted, a block link cross-link technology and a joint verification mode are utilized to ensure the isolation, supervision decentralized, safety and non-tamper property of block link data, and a multiplex method is utilized to improve the efficiency of inter-link interaction and the utilization rate of a network.
As shown in fig. 3, an embodiment of the present invention further provides a cross-chain logistics business management method, which mainly includes step 310, step 320, and step 330.

In this embodiment, the first metadata is used to indicate that the source blockchain has performed an information query to the child blockchain.
It should be noted that the metadata can effectively help technicians and service personnel to understand, supervise and manage information such as data sources, conversion rules, data change management and the like for descriptive information of data flow direction and information resources in the cross-link operation, thereby improving the working efficiency.
It should be noted that, after receiving the query request sent by the first blockchain node corresponding to the source blockchain, the second blockchain node may generate first metadata, and store the first metadata in the corresponding blockchain, so as to serve as a credential.
In the embodiment, by generating the first metadata, the information query request of the source block chain can be conveniently recorded, and the first metadata is stored in the sub-block chain, so that the storage is left while the callback of the data is realized.

In some embodiments, generating the first metadata includes the following processes.
In this embodiment, the query result corresponding to the information query request may be determined by the intelligent contract corresponding to the sub-chunk chain, and then the hash value of the query result is calculated to obtain the hash value of the query result.
In some embodiments, the query result may be hashed to generate a digest, i.e., a query result hash value. The query result hash value may be encrypted by the private key of the node.
On the basis, the first metadata can be determined based on the hash value of the query result and the timestamp corresponding to the information query request sent to the current node.
It is understood that the first metadata further includes the query index, the IP addresses of the nodes corresponding to the data sender and the data receiver.
The block chain link points of the sub-block chain can generate a section of data packet to be sent, namely query feedback information, according to the query result hash value and the time stamp encrypted by the private key, and the digital signature of the data packet is the content encrypted by the private key.
And calculating the abstract of the data packet by using the hash algorithm with the same encryption process at the block chain node of the source block chain for receiving the query feedback information, encrypting the abstract by using the public key of the second block chain node of the sub-block chain, decrypting the digital signature, and comparing the two to realize signature verification.
