Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations or operations have not been shown or described in detail to avoid obscuring aspects of the invention.
The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.
The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
Fig. 1 schematically shows a flowchart of a management method of a blockchain network according to a first embodiment of the present invention, and an execution subject of the management method may be a server or a terminal device or the like as a blockchain node.
As shown in fig. 1, the management method of the blockchain network according to the first embodiment of the present invention includes the following steps S110, S120, and S130, which are described in detail below:
in step S110, the number N of blocks and the number N of block link points in the block chain network are obtained.
In one embodiment of the present invention, the number of blockchain nodes may be obtained by obtaining a common configuration parameter in the blockchain network. Meanwhile, when one blockchain node is added into the blockchain network, the existing number of blocks in the blockchain network can be acquired, and when a new block is generated, each blockchain node can acquire the newly generated block due to broadcasting in the blockchain network, so that the number of blocks in the blockchain network can be determined.
In step S120, determining the number P of blocks to be stored in each block link point according to the number N of blocks in the block chain network and the number N of block link points, where P is the number of blocks to be stored in each block link point
In an embodiment of the present invention, since the number of blocks in the blockchain network varies, the number of blocks that each blockchain node needs to store may be determined at intervals, or the number of blocks that each blockchain node needs to store may be determined again after a new block is generated in the blockchain network.
In step S130, according to the number of blocks that need to be stored in each block link point, P blocks are selected from the block chain network and stored in the storage space corresponding to the block link point.
In an embodiment of the present invention, each block link point may randomly select P blocks from the block link network to be stored in the storage space corresponding to the block link point. The storage space corresponding to the block link point may be a local storage space and/or a non-local storage space (e.g., a cloud storage space, etc.).
According to the technical scheme of the embodiment shown in fig. 1, each block link point does not need to store one copy of finished block chain data, so that the storage pressure of the block chain nodes is effectively reduced, and the storage efficiency can be improved. At the same time, the number of P blocks stored by each block chain node is larger than that of the other blocks
Thus is arbitrary
The block quantity stored by each block chain node can cover the blocks in the whole block chain network, and further, when the transaction data is authenticated based on the consensus mechanism, only the transaction data needs to be authenticated
The validity of the block data can be confirmed by the random combination of the block chain nodes, and the block data is compared without all the block chain nodes participating in operation, so that the authentication efficiency of the block data in a block chain network is improved, and the overall information processing pressure of the block chain nodes can be reduced.
Based on the technical solution of the embodiment shown in fig. 1, as shown in fig. 2, the management method of the blockchain network according to the second embodiment of the present invention includes the following steps S210, S220, and S230, which are described in detail as follows:
in step S210, the acquired transaction data is stored in the first blockchain network.
In one embodiment of the invention, the transaction data may be data generated internally within a company or enterprise that needs to be stored in the blockchain network.
In one embodiment of the invention, the transaction data generated internally within the company or enterprise may be obtained in real time or periodically (fixed or variable periodically).
In step S220, the transaction data stored in the first blockchain network is periodically broadcasted to the second blockchain network.
In the embodiment of the present invention, the step S220 periodically broadcasts the transaction data stored in the first blockchain network to the second blockchain network, which mainly includes the following two specific embodiments:
example 1:
in one embodiment of the invention, the transaction data stored in the first blockchain network for the predetermined period of time may be broadcast to the second blockchain network every predetermined period of time. If the generation frequency of the transaction data is higher, the frequency of storing the transaction data into the first blockchain network is also higher, so that the transaction data stored into the first blockchain network can be broadcasted into the second blockchain network at a short time interval; conversely, if the generation frequency of the transaction data is small, the frequency of storing the transaction data into the first blockchain network is also small, so that the transaction data stored into the first blockchain network can be broadcasted into the second blockchain network at a longer time interval, that is, the predetermined time length and the generation frequency of the transaction data are in an inverse correlation relationship.
Example 2:
in one embodiment of the invention, a data amount of transaction data stored into a first blockchain network may be detected; if the data volume of the transaction data stored in the first blockchain network in any time period is detected to reach a data volume threshold value, the transaction data stored in the first blockchain network in the time period is broadcasted to the second blockchain network. The technical scheme of the embodiment enables the transaction data to be broadcast to the second blockchain network every time a certain amount of transaction data is stored in the first blockchain network.
In step S230, after the block link points in the second blockchain network agree on the transaction data, the transaction data is stored in the second blockchain network.
In one embodiment of the invention, the first blockchain network shown in fig. 2 may be a private chain network of an enterprise and the second blockchain network may be a federation chain network. Because the private chain only limits the access and transaction of users in an enterprise, an organization and an organization, and the nodes in the private chain are limited and controllable, the private chain can have extremely high transaction speed, better privacy protection, lower transaction cost, is not easy to be attacked maliciously, and can perform identity authentication, thereby effectively preventing the problem that a single node in the enterprise, the organization or the organization intentionally hides or tampers with data. Meanwhile, the transaction data stored in the private chain network can be broadcasted to the alliance chain network, so that the transaction data in the private chain network can be authenticated by the public alliance chain network.
It should be noted that the block link points in the first block chain network and the second block chain network shown in fig. 2 can store blocks according to the technical solution of the embodiment shown in fig. 1.
In an embodiment of the present invention, the transaction data stored in the first blockchain network and/or the second blockchain network may include a file, such as a claim evidence file, and since the data volume of such a file is large, direct storage into a block may cause problems of low storage efficiency and excessive block information volume, for the storage manner of such a file, in an embodiment of the present invention, a link address of such a file may be generated, and then the link address may be stored into a block of the blockchain network, and the file itself may be stored into a designated storage space outside the block, such as into a cloud storage space, or into a local storage space of a blockchain node.
In an embodiment of the present invention, when generating the link address of the file, the file may be encrypted by a hash algorithm to obtain a hash value, and then the hash value is used as a link value to generate the link of the claim evidence file.
In addition, in an embodiment of the present invention, the file may be subjected to redundancy encoding processing, and then the file subjected to redundancy encoding processing is stored in a designated storage space outside the block, so that the reliability of file storage may be improved.
According to the technical scheme of the embodiment, the link of the file is stored in the block of the block chain network, and the file is stored in the designated storage space except the block, so that the condition that the stored link address cannot be tampered is ensured, and the problems of low storage efficiency and overlarge block information caused by storing the file with large data volume into the block can be avoided.
The implementation details of the embodiment of the present invention are described in detail below with reference to fig. 3 to 4:
as shown in fig. 3, a management method of a blockchain network according to a third embodiment of the present invention includes the following steps:
step S310, building a blockchain node and a blockchain network.
In one embodiment of the invention, after the blockchain node is selected, a blockchain network may be constructed based on the selected blockchain node. For example, a blockchain network may be constructed with insurance company base business as a minimum node and based on the participation of one or more insurance groups/companies.
Step S320, store the transaction data based on the data structure and storage method in the embodiment of the present invention.
In one embodiment of the invention, the transaction data may be insurance transaction information including inputs to the transaction and outputs from the transaction. The input of the transaction can be an application record, the material provided by claim payment and the public key and signature of the transaction acceptors; the output of the transaction may be the amount of the check claim to the insurable beneficiary, the public key of the beneficiary, etc. Alternatively, the data structure of the insurance transaction information may be as shown in table 1:
TABLE 1
In the data structure shown in table 1, since the claim proof material usually includes some information with a relatively large data volume, such as images and documents, in order to improve the storage efficiency and solve the problem of excessive block information, in the embodiment of the present invention, a relatively large underwriting evidence file, such as an image, may be stored in a block in a linked form, where the linked value is a hash value obtained by encrypting the underwriting evidence file through a hash function, such as SHA1, and the way of obtaining a pointer link through the hash function can ensure that the content cannot be tampered. The actual underwriting evidence file can be stored in the local storage device of the block chain node and can also be stored in a cloud storage mode. Meanwhile, in order to ensure high reliability of storage of the proof document of the nuclear protection, the proof document of the nuclear protection may be stored by using a redundant coding method, for example, RS coding (Reed-Solomon codes, which is a forward error correction channel coding that is effective for a polynomial generated by correcting oversampled data) or LDPC (Low Density Parity Check Code) coding method, etc. may be used to perform redundant coding processing on the proof document of the nuclear protection.
And step S330, information storage is carried out through the combination of the private chain and the public alliance chain.
In an embodiment of the present invention, transaction information generated in real time inside an enterprise may be stored in a private chain of the enterprise according to a format shown in table 1, and at a time interval T, the enterprise transaction information occurring in the time interval is sent to a public alliance chain in a broadcast manner, and a node in the alliance chain verifies the validity of the transaction and completes the recording of the transaction. The time interval T can be adjusted according to the frequency of the occurrence of the transaction, and if the frequency of the occurrence of the transaction is high in a certain period of time, the T is reduced; otherwise, T is increased. Because the private chain only limits the access and transaction of users in an enterprise, an organization and an organization, and the nodes in the private chain are limited and controllable, the private chain can have extremely high transaction speed, better privacy protection, lower transaction cost, is not easy to be attacked maliciously, and can perform identity authentication, thereby effectively preventing the problem that a single node in the enterprise, the organization or the organization intentionally hides or tampers with data. Meanwhile, the transaction data stored in the private chain network can be broadcasted to the alliance chain network, so that the transaction data in the private chain network can be authenticated by the public alliance chain network.
In step S340, multiple nodes are randomly combined to perform authentication processing.
In one embodiment of the present invention, assuming that the number of blocks in a blockchain network (such as the aforementioned private chain and public alliance chain) is N, and the number of nodes in the blockchain network is N, for any node, P blocks from the N blocks can be randomly selected to be stored locally, so that P satisfies P
Because each block chain node only stores P blocks, and P is less than the number N of the blocks in the block chain network, each block chain link node does not need to store one copy of finished block chain data, the storage pressure of the block chain node can be effectively reduced, and the storage efficiency can be improved. At the same time, the number of P blocks stored by each block chain node is larger than that of the other blocks
Thus is arbitrary
Number of blocks stored by block link pointThe block in the whole block chain network can be covered, and then when the transaction data is authenticated based on the consensus mechanism, only the block is needed to be covered
The validity of the block data can be confirmed by the random combination of the block chain nodes, and the block data is compared without all the block chain nodes participating in operation, so that the authentication efficiency of the block data in a block chain network is improved, and the overall information processing pressure of the block chain nodes can be reduced.
In step S350, the optimized system parameters are continuously updated through system evaluation.
In an embodiment of the invention, whether the business requirements are met or not can be evaluated by detecting the transaction throughput (i.e. the highest number of transactions that can be completed in a unit time) of the blockchain network, and various parameters of the optimization system are continuously updated based on the evaluation result, so that the efficiency and reliability of system information storage and information authentication are continuously improved.
The technical scheme of the embodiment shown in fig. 3 can greatly improve the efficiency of information storage and authentication in the blockchain network, thereby greatly improving the efficiency of operations such as transaction and confirmation of the whole blockchain network, and being capable of promoting the application of the blockchain technology in blockchain network nodes with relatively limited storage and processing capabilities.
Embodiments of the apparatus of the present invention are described below with reference to the accompanying drawings.
Fig. 4 schematically shows a block diagram of a system for storing and authenticating information in a blockchain network according to an embodiment of the present invention.
Referring to fig. 4, a system for storing and authenticating information in a blockchain network according to an embodiment of the present invention includes: a blockchain network building subsystem 410, a data format definition subsystem 420, a private chain and public alliance chain combining subsystem 430, a multi-node random combination authentication subsystem 440, and an information storage and information authentication evaluation subsystem 450.
The blockchain network building subsystem 410 is responsible for building, updating and maintaining the blockchain nodes and the blockchain network. For example, a blockchain network may be constructed with insurance company base business as a minimum node and based on the participation of one or more insurance groups/companies.
Data format definition subsystem 420 may store transaction data according to the data structure shown in table 1 above. For example, the transaction data may be insurance transaction information including inputs to the transaction and outputs from the transaction. The input of the transaction can be an application record, the material provided by claim payment and the public key and signature of the transaction acceptors; the output of the transaction may be the amount of the check claim to the insurable beneficiary, the public key of the beneficiary, etc.
The private chain and public alliance chain combining subsystem 430 can store transaction information generated in real time in an enterprise into the private chain of the enterprise according to a format shown in table 1, and at the same time, at a certain time interval T, send the enterprise transaction information generated in the certain time period to the public alliance chain in a broadcasting mode, verify the validity of the transaction by a node in the alliance chain, and complete the recording of the transaction. The time interval T can be adjusted according to the frequency of the occurrence of the transaction, and if the frequency of the occurrence of the transaction is high in a certain period of time, the T is reduced; otherwise, T is increased.
The multi-node random combination authentication subsystem 440 is configured to control the number of blocks stored in a node, for example, the number of blocks in a blockchain network (such as the aforementioned private chain and public alliance chain) is N, and the number of nodes in the blockchain network is N, so that for any node, P blocks from the N blocks can be randomly selected to be stored locally, so that P satisfies P
Because each block chain node only stores P blocks, and P is less than the number N of the blocks in the block chain network, each block chain link node does not need to store one copy of finished block chain data, the storage pressure of the block chain node can be effectively reduced, and the storage efficiency can be improved. At the same time, the number of P blocks stored by each block chain node is larger than that of the other blocks
Thus is arbitrary
The block quantity stored by each block chain node can cover the blocks in the whole block chain network, and further, when the transaction data is authenticated based on the consensus mechanism, only the transaction data needs to be authenticated
The validity of the block data can be confirmed by the random combination of the block chain nodes, and the block data is compared without all the block chain nodes participating in operation, so that the authentication efficiency of the block data in a block chain network is improved, and the overall information processing pressure of the block chain nodes can be reduced.
The information storage and authentication subsystem 450 may detect the transaction throughput (i.e., the highest number of transactions that can be completed in a unit time) of the blockchain network to evaluate whether the transaction throughput meets the enterprise requirements, and continuously update and optimize various parameters of the system based on the evaluation result to continuously improve the efficiency and reliability of system information storage and authentication.
