Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
FIG. 1 is an application environment diagram of a blockchain-based information processing method in one embodiment. Referring to fig. 1, the blockchain-based information processing method is applied to a blockchain-based information processing system. The blockchain-based information processing system involves two blockchains, including: one or more first blockchain nodes 110 of a first blockchain, one or more second blockchain nodes 120 of a second blockchain, the first blockchain nodes 110 and the second blockchain nodes 120 being connected by a network. When the first block chain node receives information to be stored to be processed, the information to be processed is stored into a block of the first block chain, the block is marked as a target block, and a block characteristic value of the target block is obtained and sent to the second block chain node for storage. In other embodiments, the blockchain-based information processing system described above also relates to the terminal 130, in which embodiments the node 110 of the first blockchain obtains the information to be processed from the terminal 130.
Wherein, the first blockchain node 110 may be a terminal or a server responsible for maintaining the operation of the first blockchain, and the second blockchain node 120 may be a terminal or a server responsible for maintaining the operation of the second blockchain; the terminal 130 may be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The server may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers.
As shown in FIG. 2, in one embodiment, a blockchain-based information processing method is provided. The present embodiment is mainly illustrated by the application of the method to the first blockchain node 110 in fig. 1. Referring to fig. 2, the blockchain-based information processing method specifically includes steps S210 to S230.
Step S210, obtaining information to be processed.
The information to be processed is information to be stored in the block chain; the information to be processed may be any information that the user wishes to store through the blockchain, such as transaction information, electronic evidence information, creative work, and so forth. In a specific embodiment, when a user needs to store information into a blockchain, the information to be processed is written into a specific field through an information storage interface of a first blockchain provided by a first blockchain node, namely, a process of acquiring the information to be processed corresponding to the first blockchain node.
Step S220, the information to be processed is stored in the target block of the first block chain, and the characteristic value of the target block is obtained.
When the node of the first blockchain acquires the information to be processed, the information to be processed is stored in a block of the first blockchain, specifically, after the information to be processed is verified, the information to be processed is written into a block body of the block in the first blockchain; in this embodiment, the block is designated as the target block; it will be appreciated that the target block should be the most recent block in the first blockchain at the current time.
After the information to be processed is written into the target block of the first blockchain, the first blockchain generates a unique identifier of the target block, and in this embodiment, the unique identifier of the target blockchain generated by the first blockchain is recorded as a target block characteristic value of the target block. In one embodiment, the target block characteristic value may be a block hash value of the target block; further, the chunk hash value of the target chunk may be determined in any manner that may be implemented. For example, a block hash value of the target block may be obtained by performing a hash operation on the target block by calling a hash function. The hash function is a function of compressing an input message of an arbitrary length to a message digest of a certain fixed length; and inputting the message needing to be subjected to hash operation into a hash function to obtain a message digest with a fixed length. Common hash algorithms include MD4 (Message Digest4 ), MD5 (Message Digest5, message Digest 5), SHA (Secure Hash Standard, secure hash standard algorithm), and the like.
Step S230, generating a first information storage request based on the characteristic value of the target block, and sending the first information storage request to the node of the second block chain; the first information storage request is for a node of the second blockchain to store the characteristic value of the target block in the second blockchain.
Wherein, a node of a blockchain may refer to each client or server sharing data in the blockchain. Each node may receive input information while operating normally and maintain data shared in the blockchain based on the received input information. In order to ensure the information intercommunication of all nodes in the block chain, information connection can exist between every two nodes in the block chain, and the nodes can transmit information through the information connection. For example, when any node in the blockchain receives input information, other nodes in the blockchain acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the same blockchain are consistent.
For each node in the same blockchain, the node identification corresponding to the node is provided, and each node in the blockchain can store the node identifications of other nodes in the blockchain so as to broadcast the generated blocks to other nodes in the data sharing system according to the node identifications of the other nodes. Each node can maintain a node identification list, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an IP (Internet Protocol, protocol interconnecting between networks) address, or any other information that can be used to identify the node.
In this embodiment, the node of the first blockchain may be any node in the first blockchain, and any node of the first blockchain may store information in the first blockchain; similarly, the node of the second blockchain may be any node in the second blockchain. In one embodiment, a node of one first blockchain may only remain in communication with nodes of one or more second blockchains; in another embodiment, the nodes of one first blockchain are in communication with the nodes of all second blockchains.
In the embodiment of the application, after information is stored in the first blockchain, the block characteristic value corresponding to the block (target block) stored in the information in the first blockchain is stored in the second blockchain, so that in the embodiment, after the node of the first blockchain acquires the block characteristic value of the target block generated by the first blockchain, an information storage request is generated according to the target block characteristic value, and is recorded as the first information storage request in the embodiment, and the first information storage request is sent to the node of the second blockchain to request the node of the second blockchain to store the target block characteristic value in the second blockchain. The generated first information storage request carries the characteristic value of the target block.
According to the information processing method based on the block chain, the received information to be processed is stored in the block of the first block chain, the characteristic value of the block is sent to the node of the second block chain, and the node of the second block chain stores the characteristic value of the block stored with the information to be processed in the second block chain; according to the method, whether the information stored in the first block chain is tampered or not can be verified through the block characteristic values stored in the second block chain, the difficulty of tampering the information is improved, and therefore the public confidence of the information is improved.
In one embodiment, the blockchain-based information processing method further includes the steps of:
receiving a second information storage request sent by a node of a second block chain; the second information storage request carries the block characteristic value of the block in the second block chain; and storing the block characteristic values of the blocks in the second block chain into the first block chain according to the second information storage request.
The second blockchain is used for storing the block characteristic value of the target block after the information to be processed is stored in the target block of the first blockchain in the above embodiment. In this embodiment, the node of the first blockchain receives an information storage request (second information storage request) sent by the node of the second blockchain, and stores the block characteristic value in the second blockchain stored in the second information storage request into the first blockchain. That is, in this embodiment, not only the block characteristic value generated in the first block chain is stored in the second block chain, but also the block characteristic value of the block generated in the second block chain is stored in the first block chain, so that the two block chains are bound to each other, if the information stored in the target block in the first block chain is tampered, the block characteristic value of the target block will also change, at this time, the block characteristic value corresponding to the target block cannot be found in the second block chain, so that the difficulty of tampering is increased for the information stored in the first block chain, and similarly, the block characteristic value of the block generated in the second block chain is also stored in the first block chain, so that the difficulty of tampering of the information stored in the second block chain can also be increased.
In the above information processing method based on the blockchain, the first blockchain and the second blockchain may be respectively used as different service directions to provide services for different users, for example, two blockchains are respectively a blockchain a owned by the enterprise 1 and a blockchain B owned by the enterprise 2, in one embodiment, the blockchain a may be the first blockchain in the embodiment of the present application, and the blockchain B is the second blockchain; in another embodiment, the first blockchain may also be blockchain B and the second blockchain a. That is, in the present application, the first blockchain and the second blockchain are bound, the block characteristic value corresponding to the target block where the information stored in the first blockchain is located is stored in the second blockchain, and the block characteristic value of the block where the information stored in the second blockchain is located is stored in the first blockchain, so that the difficulty of tampering the stored information in the first blockchain and the second blockchain is increased, and the public confidence of the information stored in the first blockchain and the second blockchain is improved.
Further, in one embodiment, when the first blockchain and the second blockchain receive the blockfeature value sent by the opposite node, the blockfeature value in the opposite blockchain is actually used as information to be stored in the blockchain, and the information is stored in a block in each blockchain separately. In one embodiment, a node of a first blockchain determines a store operation based on the source of information to be stored (either the information to be processed or a blocky characteristic value in a second blockchain) upon receipt of the information. For example, when the node of the first blockchain obtains the information to be processed, determining that the source of the information to be processed is the information directly uploaded by the user, or determining that the information to be processed is the information which is not sent by the node of the second blockchain, after storing the information to be processed into the target block of the first blockchain, the method further comprises the steps of obtaining the target block characteristic value of the target block, generating an information storage request according to the target block characteristic value, and sending the request to the node of the second blockchain; when the node of the first blockchain receives the information to be stored (the block characteristic value of the second blockchain) and determines that the source of the information to be stored is the node of the second blockchain, the block characteristic value of the second blockchain is stored in the latest block of the first blockchain.
In other embodiments, when the node of the first blockchain receives the new information to be stored, the node may also determine the save operation to be executed according to the information content to be stored, that is, when the first blockchain receives the information to be processed and receives the block feature value in the second blockchain, the node executes the different save operation according to the information content; for example, when the node of the first blockchain generates a first information storage request according to the target blockfeature value, the first information storage request carries a blockfeature value identifier, so that when the second blockchain link point receives the information storage request carrying the blockfeature value identifier, only the blockfeature value carried in the second blockchain is stored in the block of the second blockchain; similarly, when the first blockchain node receives the identifier of the blockfeature value carried in the second information storage request, the first blockchain node only stores the blockfeature value in the second blockchain carried in the second information storage request into the first blockchain. It can be appreciated that in this embodiment, when the first blockchain node receives the information to be processed that does not carry the identifier of the blockfeature value, the first blockchain node stores the information to be processed, and sends the blockfeature value of the target block storing the information to be processed to the second blockchain for storing.
By the information processing method based on the blockchain, in the embodiment that each new block is generated in the first blockchain, the block characteristic value of the new block is stored in the second blockchain, the problem that after the first blockchain stores the block characteristic value of the second blockchain, the characteristic value corresponding to the block storing the block characteristic value of the second blockchain is stored in the second blockchain again can be avoided.
Alternatively, in another embodiment, generating the first information storage request based on the target block characteristic value includes: and acquiring target block characteristic values of each target block generated between the current moment and the last moment every preset time, and generating a first information storage request based on the characteristic values of each target block.
In this embodiment, after storing information (information to be processed or a second blockchain node) in the first blockchain, the node of the first blockchain stores the block characteristic value of the new block in the second blockchain, but stores the block characteristic value of the new block generated in the first blockchain in the second blockchain at intervals. The method specifically comprises the following steps: and acquiring target block characteristic values of each target block generated between the current moment and the last moment in the first block chain at intervals of preset time, and initiating a first information storage request to the second block chain according to each target block characteristic value. In one embodiment, a node of the second blockchain receives a first information storage request, detects that the node carries a plurality of target block characteristic values, and stores the plurality of target block characteristic values into one block in the second blockchain. Further, storing the plurality of target block feature values into one block may be achieved by any of the methods.
In one embodiment, the above-mentioned information processing method based on a blockchain further includes the steps of, after generating the first information storage request based on the characteristic value of each target block: setting a stored identifier for the target block and a timer for a predetermined time; when the timer is detected to be overtime, starting to traverse forward from the first target block generated at the current moment until the first second target block with the stored identifier is found; at this time, block characteristic values of all blocks between a target block (first target block) generated at the current time and a target block (second target block) at the previous time are acquired, and a first information storage request is generated according to the block characteristic values and sent to a node of the second blockchain. It will be appreciated that the predetermined time may be set according to the actual situation. The last time represents the time when the first information storage request is generated based on the characteristic value of the target block and the first information storage request is initiated to the node of the second block chain.
It may be understood that, in the nodes of the second blockchain, the block characteristic values of the new blocks generated in the second blockchain may be packaged and stored in the first blockchain at intervals of a predetermined time, that is, the nodes of the first blockchain receive the second information storage request sent by the nodes of the second blockchain at intervals of a predetermined time, and store the block characteristic values in each second blockchain carried in the second information storage request in the first blockchain. In one embodiment, the predetermined times set in the first and second blockchains may or may not be the same.
In another embodiment, generating a first information storage request based on each target block characteristic value includes: integrating the characteristic values of all target blocks into a characteristic value file; generating a first information storage request based on the eigenvalue file; the first information storage request is for a node of the second blockchain to store a characteristic value file in the second blockchain.
In this embodiment, the block characteristic values of the new target blocks generated in the first block chain are stored in the second block chain at intervals, and in this embodiment, after the node of the first block chain obtains the target block characteristic values of each target block generated between the current time and the previous time, the node integrates the target block characteristic values into a characteristic value file, and then generates a first information storage request according to the characteristic value file and sends the first information storage request to the node of the second block chain, so that the node of the second block chain stores the characteristic value file in the second block chain.
In the information processing method based on the blockchain, the block characteristic value of the target block in the first blockchain is stored in the second blockchain at intervals of preset time, so that the problem of waste of block storage resources caused by the fact that one block is only used for storing the block characteristic value in the opposite blockchain can be avoided; meanwhile, in the embodiment, the blockchain node only needs to execute the operation of sending the blockcharacteristic value to the second blockchain storage once in the preset time, and only receives the blockcharacteristic value in the opposite blockchain for storage in the preset time, so that the workload of the blockchain node can be reduced to a certain extent.
In one embodiment, the above-mentioned information processing method based on blockchain, as shown in fig. 3, further includes steps S310 to S350.
Step S310, receiving an information verification request; the information verification request carries key information of the information to be verified.
After storing the information in the blockchain, the blockchain may provide a function of checking the information, which in this embodiment is a process of verifying the information stored in the first blockchain.
The user may send an information verification request carrying information to be verified to a node of the first blockchain to request verification of authenticity of the information to be verified. The key information of the information to be verified can be a key word of the information to be verified, or can represent a unique identifier of the information to be verified, and it can be understood that a certain corresponding relation exists between the key information of the information to be verified and the information to be verified, if the information to be verified is already stored in the first blockchain, the corresponding stored information can be found in the first blockchain according to the key information of the information to be verified.
Step S320, searching whether stored information corresponding to key information of the information to be verified exists in the first blockchain, and obtaining a first information searching result.
The node of the first blockchain searches in the first blockchain according to the key information carried in the information verification request, and obtains an information searching result according to whether the corresponding information is searched, and in this embodiment, the result of searching information in the first blockchain is recorded as a first information searching result. As can be appreciated, when the stored information corresponding to the key information of the information to be verified is found in the first blockchain, a first information search result is obtained, wherein the search is successful; and when the stored information corresponding to the key information of the information to be verified is not searched in the first blockchain, obtaining a first information searching result of searching failure. Further, in one embodiment, when the first information search result of the search failure is obtained, a response of the verification failure is returned. The stored information represents information found in the first blockchain based on key information of the information to be verified.
Step S330, when the first information searching result is that searching is successful, a first eigenvalue inquiry request is generated according to the block eigenvalue corresponding to the stored information.
The node of the first blockchain obtains a first information searching result of successful searching, which means that the stored information corresponding to the key information of the information to be verified is searched in the first blockchain, but whether the stored information is tampered or not can not be determined, so in the embodiment, a first characteristic value inquiry request is generated according to the block characteristic value of the block where the searched stored information is located, and whether the stored block characteristic value is corresponding to the searched second blockchain or not is searched. In this embodiment, a eigenvalue query request sent by a node of a first blockchain to a second blockchain is denoted as a first eigenvalue query request.
Step S340, a first eigenvalue query request is sent to a node of a second blockchain; the first eigenvalue inquiry request is used for enabling the node of the block chain to search whether the block eigenvalue corresponding to the stored information exists in the second block chain or not, and obtaining a first eigenvalue searching result.
And sending the first characteristic value query request to a node of the second blockchain, so that the node of the second blockchain searches whether the block characteristic value corresponding to the storage information exists in the second blockchain according to the request. The node of the second block chain obtains a first characteristic value searching result according to whether the corresponding block characteristic value is searched; it can be understood that when the block characteristic value corresponding to the stored information is found in the second blockchain, a first characteristic value finding result of successful finding is obtained, and when the block characteristic value corresponding to the stored information is not found in the second blockchain, a first characteristic value finding result of failed finding is obtained.
Step S350, when the first characteristic value searching result returned by the node receiving the second blockchain is searching success, a verification success response is returned.
When the node of the second blockchain returns a second characteristic value searching result of successful searching, the successful verification of the key information in the first blockchain and the second blockchain according to the information to be verified is judged, and therefore a response of successful verification is returned to the equipment sending the information verification request. It will be appreciated that when the second eigenvalue search result returned by the node that receives the second blockchain is a search failure, it indicates that verification fails, and a response of verification failure is returned to the device that sent the information verification request.
In the above embodiment, if the information to be verified has a storage record in the first blockchain, the corresponding storage information may be found in the first blockchain through the key information of the information to be verified; meanwhile, if the stored information is not tampered in the first block chain, the block characteristic value corresponding to the stored information can be found in the second block chain; by the method, whether the information to be verified is stored in the first block chain or not and whether the information to be verified is tampered or not can be verified. Similarly, information stored in the second blockchain may also be verified in the first blockchain as to whether it has been tampered with.
In one embodiment, as shown in fig. 4, the above-mentioned blockchain-based information processing method further includes steps S410 to S430.
In step S410, a second eigenvalue query request sent by the node of the second blockchain when the second information search result is that the search is successful is received.
Wherein the second eigenvalue query request carries block eigenvalues of blocks in the second blockchain; and the second information searching result is a result of searching whether information corresponding to the second information verification request exists in the second blockchain when the node of the second blockchain receives the second information verification request.
In this embodiment, the same as searching information in the first blockchain, because the block characteristic value corresponding to the information stored in the second blockchain is stored in the first blockchain, when the authenticity of the stored information is expected to be verified in the second blockchain, the node of the second blockchain receives the second information verification request, and the node of the second blockchain searches whether the corresponding stored information exists in the second blockchain according to the second information verification request, so as to obtain a second information searching result; and when the second information searching result is that searching is successful, the node of the second blockchain sends a second characteristic value inquiry request to the node of the first blockchain.
Step S420, searching whether the block characteristic value of the block in the second block chain exists in the first block chain according to the second information storage request, and obtaining a second characteristic value searching result.
When a node of the first block chain receives a second characteristic value query request sent by the node of the first block chain, searching whether a block characteristic value of a block in the second block chain carried by the second information query request exists in the first block chain or not, and obtaining a second characteristic value search result; as can be appreciated, when the block feature value of the block in the second blockchain is found in the first blockchain, a second feature value search result is obtained, wherein the search is successful; and when the block characteristic values of the blocks in the second block chain are not found in the first block chain, obtaining a second characteristic value searching result of searching failure.
Step S430, returning the second eigenvalue lookup result to the node of the second blockchain.
And returning the obtained second characteristic value searching result to the node of the second block chain by the node of the first block chain, so that the node of the second block chain determines a verification response corresponding to the second information inquiry request according to the second characteristic value searching result.
Further, in one embodiment, after returning the verification success response, the blockchain-based information processing method further includes: when an information acquisition request for acquiring information to be verified is received, acquiring storage information corresponding to key information of the information to be verified; and returning the storage information corresponding to the key information of the information to be verified.
When a response of successful verification is returned to the terminal that initiates the first information verification request, an information acquisition request initiated by the terminal may also be received, where in this embodiment, the information acquisition request is used to retrieve storage information (corresponding to key information of the information to be verified) from the first blockchain for viewing by the user. If the information stored in the blockchain has privacy, it is usually selected to cooperate with a public agency (such as a judicial authentication center, a worker, etc.), and the user can only check or verify the information in the first blockchain (or the second blockchain) through the public agency.
In one embodiment, taking information stored in the blockchain as an example, fig. 5 is a schematic diagram of storing information in the blockchain in this embodiment, the evidence a (i.e. the information to be processed) is sent to the first blockchain for storing, and the block characteristic value of the target block in which the evidence a is stored is sent to the second blockchain for storing. Similarly, when evidence B (i.e., information to be processed) is stored in the second blockchain, the blockfeatures of the target blockchain in which evidence B is stored are sent to the first blockchain for storage. Evidence a may be any information that is desired to ensure authenticity, such as a bank's bond, a creative work, etc.
According to the information processing method based on the blockchain, by adopting the mode of mutually binding and mutually authenticating a plurality of blockchains, once the stored data on one blockchain is modified, the characteristic value of the block storing the stored data is changed, so that the difficulty of tampering the stored information in the blockchain is further increased, and the accuracy and the public confidence of the information stored in the blockchain are improved; the problem that stored information lacks public confidence caused by the fact that any party falsifies the stored information in the blockchain can be avoided.
FIGS. 2-4 respectively correspond to a flow diagram of a blockchain-based information processing method in an embodiment.
