Detailed Description
For the purpose of making 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 apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes a method, a device and an electronic device for managing cross-chain logistics business with reference to fig. 1 to 6.
The cross-chain logistics service management method can be applied to the block chain nodes corresponding to the source block chains corresponding to the service order management mechanism. The blockchain node corresponding to the source blockchain corresponding to the service order management mechanism may be a server or a processor, and may be disposed in a virtual network device or an entity network device. Nodes corresponding to different blockchains can be arranged on different servers.
A blockchain is a chain that is made up of a plurality of blocks. Each block holds certain information which is linked in a chain according to the time sequence of their respective generation. This chain is kept in all servers, and the entire blockchain is secure as long as one server in the entire system can work. In this case, the servers act as blockchain nodes in the blockchain system, providing storage space and computational support for the entire blockchain system.
If the information in the blockchain is to be modified, it is necessary to sign consent of more than a certain number of nodes and modify the information in all nodes, which are usually held in different subject hands, so it is an extremely difficult thing to tamper with the information in the blockchain. Compared with the traditional network, the blockchain has two main core characteristics: firstly, the data is difficult to tamper, and secondly, the data is decentralised.
Based on this, blockchain is a new application mode of computer technology including distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc., which is essentially a de-centralized database. The blockchain may be composed of a plurality of serial transaction records (also known as blocks) that are cryptographically concatenated and protected against content, and the distributed ledgers concatenated by the blockchain enable multiple parties to effectively record transactions and permanently verify the transactions.
The cross-chain logistics service management method is applied to the block chain nodes corresponding to the source block chains corresponding to the service order management mechanism based on the block chain technology, and can simultaneously perform cross-chain operation on a plurality of sub-block chains based on the source block chains.
In some embodiments, the sub-blockchains include at least one of a first sub-blockchain corresponding to a logistics transportation and supervision organization, a second sub-blockchain corresponding to a financial management organization, and a third sub-blockchain corresponding to a logistics warehouse management organization, so as to achieve the effect that a source chain automatically sends information to the sub-chains in a cross-chain operation, thereby reducing network burden.
It will be appreciated that in the field of logistics management, and in particular cold chain logistics management, there may be included a source blockchain corresponding to a business order management entity, a first sub-blockchain corresponding to a logistics transportation and supervision entity, a second sub-blockchain corresponding to a financial management entity, and a third sub-blockchain corresponding to a logistics warehouse management entity.
As shown in fig. 1, the method for managing cross-link logistics business according to 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 of the target object to the business order. The service organization corresponding to the sub-blockchain is associated with the service order management organization of the source blockchain in the logistics service. The business order management organization may correspond to a source blockchain, the logistics transportation and administration organization may correspond to a first sub-blockchain, the financial management organization may correspond to a second sub-blockchain, and the logistic warehouse management organization may correspond to a third sub-blockchain.
The target object may be a person of a business order management organization, and may query and manage the signing information, logistics transportation and administration information, financial information, and logistic warehouse information of the business order.
The endorsement information may include the time of endorsement of the business order, the endorser, the specific logistics transportation items, the transportation time, the transportation contract, etc. The logistics transportation and supervision information can comprise logistics party selection, logistics mode, logistics path, logistics process supervision content and the like. The financial information may include information such as revenue, expense, deduction, and rewards for each of the money of the business order. The logistical warehouse information may include information related to warehouse storage of the items to be transported for each link.
The target object can realize information query input of the service order through terminal equipment or other equipment.
The various information types of the service order to be queried by the target object are not limited, and the input mode of the information query request is not limited.
In this embodiment, the source blockchain corresponding to the service order management mechanism sends the information query request to each other module corresponding to the logistics service, so that the source blockchain can directly initiate information transfer to each sub-blockchain.
It can be appreciated that after receiving the query request sent by the first blockchain node corresponding to the source blockchain, the second blockchain node corresponding to the sub-blockchain can send the query feedback information to the first blockchain node corresponding to the source blockchain 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-block chain may implement a respective function based on a corresponding smart contract.
For example, the logistics transportation and the supervision mechanism correspond to the first sub-blockchain node, which can realize the functions of data collection, data judgment, early warning processing, event transmission, event receiving, traceability verification and the like, and the functions on each sub-blockchain are not limited herein.
In this embodiment, the sub-block chain may generate first metadata corresponding to the information query request sent by the first block link, and send the query feedback information to the first block link, that is, the first metadata is used to indicate that the source block chain has queried information to the sub-block chain.
It should be noted that, the metadata can effectively help technicians and business personnel understand, supervise and manage the information such as the source of data, conversion rules, data change management and the like, so as to improve the working efficiency.
In this embodiment, by determining the first metadata, it is possible to record the information query request of the source blockchain conveniently, and actively perform the uplink certification on the sub-blockchain by using the first metadata, thereby implementing the certification of the data.
According to the method for managing the cross-chain logistics business, the source block chain actively initiates transmission and information inquiry requests to the sub-block chains, so that the cross-chain information interaction of the source block chain is realized, event information is not required to be continuously sent to the source block chain by the sub-block chain in a passive polling mode, data is sent to the source chain only when the source chain has information transmission requirements to the corresponding sub-chain, data transmission quantity and required computing capacity are reduced, and network burden and transmission cost in the cross-chain transmission process are reduced.
In the embodiment of the invention, as shown in fig. 2, the active multiplexing method can help one source block chain to call a plurality of different service sub-chains at the same time, and the plurality of different sub-chains can initiate callback to the main chain at the same time, which is different from the traditional passive event monitoring method based on polling, and greatly reduces the communication cost.
The blockchain node of the sub-blockchain can generate a section of data packet to be sent, namely inquiry feedback information, by using the hash value and the time stamp of the inquiry result encrypted by the private key, and the digital signature is the content encrypted by the private key.
The block chain node of the source block chain receiving the query feedback information calculates the abstract of the data packet by using a hash algorithm with the same encryption process, encrypts the abstract by the public key of the second block chain node of the sub block chain, decrypts the digital signature, and compares the two to realize signature verification.
In this embodiment, by encrypting the query result, security in the data transmission process can be ensured, and the first metadata includes not only the hash value of the query result, but also a timestamp that the source block chain transmits the information query request to the second block chain link, and all information of the cross-chain operation can be recorded, so that tracing and auditing of the full-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 blockchain node of a first sub-blockchain corresponding to a logistics transportation and supervision mechanism according to an intelligent contract of a source blockchain.
The intelligent contract corresponding to the first blockchain node of the first sub-blockchain can send a supervision request to the temperature sensor equipment in the cold chain logistics transportation vehicle at regular time, the temperature sensor equipment collects environmental data after receiving the request and uploads the temperature data to the blockchain platform through the node corresponding to the data collection function, and the temperature data is stored in the first sub-blockchain.
The blockchain node corresponding to the data judgment in the first sub-blockchain compares the collected data with a reasonable temperature threshold corresponding to the system setting. If the result is in a reasonable range, signing the processed data and the result by the nodes corresponding to the traceability verification, transmitting the data and the result into a file system by the nodes corresponding to the data uplink, and taking the hash value for uplink, so that the data can be stored in traceability.
If the result is not within the reasonable range of values, the data extraction hash value is wound up after the batch of products is marked as temperature anomaly while the file system stores the data. And finally, the corresponding node for early warning processing can early warn the related processing node through an early warning function for data abnormality, and inform the related processing node to process.
After processing, the first sub-blockchain may send the processing result to a source blockchain corresponding to the service order management mechanism for recording, and the source blockchain synchronizes the related data to a second sub-blockchain corresponding to the financial management mechanism, so that the second sub-blockchain performs related operations according to the corresponding intelligent contract.
According to the early warning condition, the second sub-blockchain can deduct the amount of guarantee money corresponding to the responsible nodes according to the intelligent contract, wherein each time of cross-chain operation can generate a signature and related data blocks to carry out uplink, and the tracing and auditing of all-chain nodes are guaranteed.
In some embodiments, before sending an information query request to a second block link corresponding to the sub-block chain, the method for managing a cross-chain logistics service according to the embodiment of the present invention further includes: under the condition that the business order is confirmed to be signed, data required by the sub-block chain corresponding to the business order is packed, the hash value of the business order data is extracted from the data required by the sub-block chain corresponding to the business order, and a data packet corresponding to the business order after digital signature is generated.
It will be appreciated that for each uplink service order, the service order is placed in the source blockchain.
Of course, the source blockchain initializes the address and key information of the nodes of the organization in a cross-chain environment prior to order placement. Then, after the order service is signed and up, the order management chain node distributes contracts to each sub-chain and saves the invoked metadata.
In this case, second metadata is generated that sends the data packet corresponding to the service order corresponding second blockchain node.
The data packet corresponding to the service order may be signing information, logistics transportation and supervision information, financial information, logistic warehouse information, etc. of the service order.
After each sub-block chain receives the data packet corresponding to the service order, each piece of information can be updated according to the corresponding intelligent contract.
The second metadata is used for indicating that the blockchain node corresponding to the source blockchain sends a data packet corresponding to the service order to the second blockchain node corresponding to the service order.
In some embodiments, the second metadata may be determined in the following manner.
It will be appreciated that the second blockchain node corresponding to the service order may be determined based on the intelligent contract corresponding to the source blockchain, i.e., the second blockchain node of the sub-blockchain corresponding to the service order may be determined from a plurality of nodes of the plurality of sub-blockchains.
In this case, the second metadata is determined based on the timestamp of the data packet corresponding to the service order sent to the service order corresponding second blockchain node and the service order data hash value. The service order data hash value may be set at the end of the data packet.
It is 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 of the source blockchain sending data to the sub-blockchain and a hash value of the service order data, so that accuracy, security and traceability of the data packet corresponding to the service order are ensured.
In this case, the second metadata is stored upstream and the data packet corresponding to the service order is sent to the second blockchain node.
In this embodiment, the source blockchain actively sends a data packet to each sub-blockchain, so that the automatic sending of related data required by the sub-chain is realized, the request of the sub-chain is not required, and when the sub-chain receives information and verifies that the sub-chain is successful, callback function is utilized to confirm that the call is successful.
In some embodiments, after sending the data packet corresponding to the service order to the second blockchain node corresponding to the service order, the cross-chain logistics service management method of the embodiment of the present invention further includes verification of the received data.
In this embodiment, signature verification and integrity verification may be performed on the hash value of the service order data in the data packet corresponding to the service order by the second blockchain node corresponding to the service order.
And the block chain node of the source block chain calculates the digest of the data packet by using a hash algorithm with the same encryption process, encrypts the digest by adopting a public key of a second block chain node through a client corresponding to the second block chain node, decrypts the digital signature, and compares the two to realize signature verification.
Under the condition, the integrity verification is continuously carried out on the hash value of the service order data, and under the condition that the signature verification and the integrity verification are both passed, the data packet corresponding to the service order is stored in a uplink mode, so that the integrity and the safety of the data received by the sub-link 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 property of the data by utilizing a hash mechanism and a signature mechanism, and other verification nodes request the source blockchain node to verify the correctness of the hash value through the corresponding organization node.
Meanwhile, the one-to-many cross-link communication model reduces the storage pressure, solves the problem of occupation of the traditional single-machine multi-link operation memory, and realizes the classified management of service data.
After the data packet is uplink, if other sub-block chain nodes want to perform authentication or operation, the other sub-block chain nodes can perform cross-chain authentication with the corresponding source block chain nodes by themselves.
In the cross-chain logistics service management method, an active multiplexing cross-chain calling method service model is adopted, isolation, supervision decentralization, safety and non-tamper-resistance of block chain data are guaranteed by using a block chain cross-chain technology and a joint verification mode, and the efficiency of inter-chain interaction and the utilization rate of a network are improved by using a multiplexing method.
As shown in fig. 3, the embodiment of the present invention further provides a method for managing a cross-link logistics service, which mainly includes steps 310, 320 and 330.
In this embodiment, the cross-chain logistics service management method is applied to the second blockchain node corresponding to the sub-blockchain corresponding to the service organization associated with the service order management organization in the logistics service, for example, the second blockchain node corresponding to the first sub-blockchain corresponding to the logistics transportation and supervision organization, the second sub-blockchain corresponding to the financial management organization, the third sub-blockchain corresponding to the logistic warehouse management organization, and the like.
It will be appreciated that the information query request is determined based on the information query input of the target object to the service order, and the service organization corresponding to the source blockchain is a service order management organization.
In this embodiment, the source blockchain corresponding to the service order management mechanism sends the information query request to each other module corresponding to the logistics service, so that the source blockchain can directly initiate information transfer to each sub-blockchain.
It can be appreciated that after receiving the query request sent by the first blockchain node corresponding to the source blockchain, the second blockchain node corresponding to the sub-blockchain can send the query feedback information to the first blockchain node corresponding to the source blockchain according to the corresponding intelligent contract, so that the target object can determine the queried content conveniently.
In this embodiment, the first metadata is used to indicate that the source blockchain has queried information for the sub-blockchain.
It should be noted that, the metadata can effectively help technicians and business personnel understand, supervise and manage the information such as the source of data, conversion rules, data change management and the like, so as to improve the working efficiency.
And 330, performing uplink certification on the first metadata.
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 sub-blockchain as the credential.
In this embodiment, by generating the first metadata, it is possible to record the information query request of the source blockchain conveniently, and store the first metadata in the sub-blockchain, so that the callback of the data is realized, and at the same time, the storage is left.
According to the method for managing the cross-chain logistics business, the source block chain actively initiates transmission and information inquiry requests to the sub-block chains, so that the cross-chain information interaction of the source block chain is realized, event information is not required to be continuously sent to the source block chain by the sub-block chain in a passive polling mode, data is sent to the source chain only when the source chain has information transmission requirements to the corresponding sub-chain, data transmission quantity and required computing capacity are reduced, and network burden and transmission cost in the cross-chain transmission process are reduced.
In some embodiments, the first metadata is generated, including the following process.
In this embodiment, the query result corresponding to the information query request may be determined by the intelligent contract corresponding to the sub-blockchain, and then the hash value is calculated on the query result 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 hash value of the query result. The query result hash value may be encrypted by the private key of the node.
On this basis, the first metadata may be determined based on the query result hash value and a 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 address of the node corresponding to the data sender and the data receiver.
The blockchain node of the sub-blockchain can generate a section of data packet to be sent, namely inquiry feedback information, by using the hash value and the time stamp of the inquiry result encrypted by the private key, and the digital signature is the content encrypted by the private key.
The block chain node of the source block chain receiving the query feedback information calculates the abstract of the data packet by using a hash algorithm with the same encryption process, encrypts the abstract by the public key of the second block chain node of the sub block chain, decrypts the digital signature, and compares the two to realize signature verification.
