Detailed Description
The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts steps as a sequential process, many of the steps may be implemented in parallel, concurrently, or with other steps. Furthermore, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example 1
Fig. 1 is a flowchart of a blockchain transaction query method according to an embodiment of the present application, where the embodiment is applicable to a scenario of querying transaction information occurring in a blockchain, and the method may be performed by a blockchain transaction query device according to an embodiment of the present application, where the device may be implemented by software and/or hardware, and may be integrated in an electronic device.
As shown in fig. 1, the query method of the blockchain transaction includes:
s110, acquiring a transaction inquiry request sent by a client according to a transaction number through the current node; the transaction numbers are pre-generated according to a monotonically increasing rule, and transaction information is stored in the account book of each node of the blockchain based on the transaction numbers.
The method is performed by a blockchain link point, wherein the blockchain comprises at least two nodes, and at least one current node connected with a client and other nodes except the current node are included in the at least two nodes.
It will be appreciated that the blockchain may be considered an entity, each of which may be located at different locations depending on the needs or configuration of the actual scenario. The node connected with the client currently making the query can be used as the current node, and the nodes other than the node connected with the client can be used as other nodes.
In this scheme, the client may connect with only one node of the blockchain. This avoids the complexity of the network connection. Meanwhile, through the transaction information query mechanism of the scheme, a mode that the current node can obtain accurate transaction information without constructing a client to be connected with all nodes in a network can be realized.
The transaction numbers used in the inquiry in the scheme can be pre-generated, and unique transaction numbers are set for each transaction. The transaction number may be generated by monotonously increasing, for example, 1,3,5,6,7, or may be generated by monotonously continuously increasing, for example, 1,2,3,4,5, for the sake of convenience in counting. This makes it possible to determine how many transactions have been based on the transaction number, facilitating further processing.
The transaction information may be information related to the transaction, such as a transaction number and transaction content. The transaction information may be plaintext information or encrypted information, such as information obtained by encryption with a key. Further, a hash value of the transaction content may be obtained by hash calculation. This arrangement ensures both the security of the transaction and the globally unique processing of each transaction message.
In this scheme, based on the connection relationship between the client and the current node, the client may issue a transaction inquiry request according to the transaction number. The transaction inquiry request can be a specific transaction number or a number section. Such as 0330-0350. That is, the 21 transaction information with transaction numbers 0330 to 0350 need to be queried, or one or more of the 21 transaction information need to be queried.
S120, determining whether transaction information corresponding to the transaction inquiry request exists in the account book of the current node.
Wherein, it can be known that each node is provided with an account book, and the account book is used for recording transaction information of each node on the blockchain and storing the transaction information in the account book after passing through the consensus protocol. Therefore, after the current node receives the query request, it can preferentially check whether the transaction information corresponding to the transaction query request exists in the local ledger. The query may be made, for example, by whether a transaction number or a number segment of a transaction number in the transaction query request is covered by a transaction number present in the ledger.
And S130, if the transaction information does not exist, initiating a transaction information acquisition request to other nodes of the blockchain through the current node so as to receive the transaction information returned by the other nodes and return the transaction information to the client.
When the current node does not have the transaction information, a transaction information acquisition request needs to be initiated to other nodes through the current node, and the acquisition request can be sent based on a transaction number. It can be appreciated that the current node and other nodes can be directly connected, or belong to different organizations or institutions, and information interaction can be performed through the connection relation of each node in the predetermined blockchain. In the scheme, the current node can acquire the transaction information returned by other nodes in a broadcasting mode and can return to the client.
It can be understood that in order to avoid the bayer attack, after receiving the transaction information returned by each node, confirmation of a consensus mechanism may be performed on the received transaction information returned by each other node, and when the consensus is successful, the information may be considered to be accurate, and stored in a local ledger and returned to the client.
In this solution, it should be understood that, in each process of broadcasting to return information, a problem that an individual node is disconnected due to a network or a device failure is not excluded, so each node in this solution may be understood as each node that is online and capable of receiving broadcasting or returning information, and is not limited to all other nodes.
According to the technical scheme provided by the embodiment of the application, the current node is used for acquiring a transaction inquiry request sent by a client according to a transaction number; the transaction numbers are pre-generated according to a monotonically increasing rule, and transaction information is stored in the account book of each node of the blockchain based on the transaction numbers; determining whether transaction information corresponding to the transaction inquiry request exists in an account book of the current node; if the transaction information is not available, a transaction information acquisition request is initiated to other nodes of the blockchain through the current node so as to receive the transaction information returned by the other nodes and return the transaction information to the client. By means of the scheme, the effect of ensuring the authenticity of the acquired data can be achieved without connecting the client with all nodes of the blockchain.
Example two
Fig. 2 is a flowchart of the process of generating the transaction number and storing the transaction information in the second embodiment of the present invention, and the present embodiment is optimized based on the above embodiment. The concrete optimization is as follows: the generation of the transaction number and the storage process of the transaction information comprise the following steps: generating a transaction number for each transaction in the blockchain according to a monotonically increasing sequence through a designated node, and broadcasting the transaction number to a receiving node of the blockchain; if the number of the generated transaction numbers meets the preset number, each node carries out hash operation on the transaction information of the preset number to obtain a hash value; each node signs the hash value by adopting the node key to obtain a signature value; each node uses the hash value, the transaction number range corresponding to the preset number and the signature value as broadcasting contents to broadcast to the nodes on the chain; and receiving hash values broadcasted by nodes on a chain, presetting transaction number ranges corresponding to the number as receiving contents; and if the broadcast content and the received content meet the preset conditions, storing the hash value, the transaction number range and the signature value into the account book of each node.
It can be appreciated that the execution of the present solution may be before, during or after the execution of the first solution of the embodiment, and thus, the trigger mechanism of the present solution triggers based on occurrence of transaction information, which may not conflict with the execution of the first solution of the embodiment.
As shown in fig. 2, the method of this embodiment specifically includes the following steps:
s210, generating a transaction number for each transaction in the blockchain according to a monotonically increasing sequence through a designated node, and broadcasting the transaction number to a receiving node of the blockchain.
The designated node may be one node in the blockchain, or may be a plurality of nodes, and which node is the designated node may be predetermined. The determining mode of the designated node can be determined according to the running stability of the node, and can also be determined according to the network transmission capacity of each node. In addition, the determination may be based on the node position of each node in the blockchain, for example, the node with the most connection to each organization or organization in the blockchain may be used as the designated node.
The designated node may generate a transaction number for each transaction of the blockchain in a sequential order. For example, in time series, a monotonically increasing sequence is used to generate the transaction number. Wherein the transaction number is preferably in a continuous manner. After the transaction number is obtained, the generated result of the transaction number can be carried with other receiving nodes of the blockchain of the transaction information broadcast.
S220, if the generated transaction number meets the preset number, each node carries out hash operation on the transaction information of the preset number to obtain a hash value.
The preset number may be the number of batches as hash operations, for example, every 100, 200, or every 2000, or the like. When the number of the generated transaction numbers reaches the preset number, the hash value of the current transaction information of the number can be obtained through a hash operation mode. It will be appreciated here that the nodes are still online and can perform hash operations normally.
And S230, each node signs the hash value by adopting the node key to obtain a signature value.
For example, after each node calculates its own hash value for the amount of transaction information, the key of the node, that is, the private key, may be used to sign the hash value, thereby obtaining a signed value. It can be understood that the scheme can use a private key signature, and the public key authentication mode can determine which node generates each hash value, so that the method can be used as a judging standard of whether the node is attacked. For example, by consensus, when the hash value obtained by a certain node is inconsistent, it can be determined that the node may be attacked or caused by other reasons such as data loss.
In this embodiment, optionally, the signature value includes the following contents: hash value, start transaction number and stop transaction number.
For example, the signature value is obtained by concatenating a hash value, a character string of a start transaction number and a stop transaction number, and other representations can be included, or a connection is performed between the several by fixed characters, so as to improve the readability of the signature value. By carrying the initial transaction number and the final transaction number in the signature value, it is possible to determine which transaction numbers the hash value corresponds to.
S240, each node uses the hash value, the transaction number range corresponding to the preset number and the signature value as broadcasting contents, and broadcasts the broadcasting contents to the nodes on the chain; and receiving the hash value broadcasted by the node on the chain, presetting a transaction number range corresponding to the number as the received content.
After each node obtains the hash value, the transaction number range corresponding to the preset number and the signature value, the hash value can be broadcasted to the nodes on the chain, and each piece of information broadcasted by the nodes on the face can be received.
And S250, if the broadcast content and the received content meet the preset conditions, storing the hash value, the transaction number range and the signature value into account books of all nodes.
For each node, if the broadcast content and the received content meet the consensus mechanism, it may be determined that a preset condition is met, and further, the hash value, the transaction number range, and the signature value may be stored.
It will be appreciated that each node may store the correct hash value, transaction number range, and signature value in a local ledger.
According to the technical scheme provided by the embodiment of the application, after the transaction information reaches a certain quantity, each node respectively generates the hash value and performs signature processing, and finally the transaction information with the hash value, the transaction number range and the signature value is stored in the account book of each node, so that the common storage of the transaction information can be completed. After the arrangement, the transaction information of each batch can be stored according to the transaction numbers, when the client needs to inquire the transaction information, the inquiry of the information can be realized without connecting all nodes of the whole blockchain, the information inquiry efficiency is improved, and the complexity of network connection and the network load consumption caused by network data transmission can be effectively avoided.
On the basis of the above embodiments, optionally, the step of initiating, by the current node, a transaction information acquisition request to other nodes of the blockchain to receive transaction information returned by the other nodes includes:
And initiating a transaction information acquisition request to other nodes of the blockchain through the current node so that the other nodes can query the transaction information recorded in the account book of the node, determine target transaction information and return the target transaction information to the current node.
In one case, the current node initiates a transaction information acquisition request to other nodes of the blockchain, and if the transaction information exists in the account book of the other nodes, the target transaction information can be directly acquired from the account book of the other nodes, and returned to the current node, and returned to the client by the current node. Therefore, the response speed is high, the client is not required to be connected with other nodes, and the method is simple and efficient.
On the basis of the above embodiments, optionally, the step of initiating, by the current node, a transaction information acquisition request to other nodes of the blockchain to receive transaction information returned by the other nodes includes:
initiating a transaction information acquisition request to other nodes of a blockchain through the current node so that other nodes can carry out hash operation on transaction information containing a transaction number range of the transaction number to obtain a target hash value, and signing the target hash value to obtain a target signature value;
Receiving received contents which are returned by other nodes and comprise a target hash value, a transaction number range and a target signature value, and if the received contents meet preset conditions, storing the received contents into an account book.
In another case, if the transaction information does not exist in other nodes or the other nodes have the capability of regenerating the transaction information by calculating the hash value, the hash operation can be performed again through each node to obtain the target hash value, and the respective calculated target hash values are signed respectively to obtain the target signature value. Therefore, the received content which is returned by other nodes and contains the target hash value, the transaction number range and the target signature value can be received, the judgment of the consensus mechanism is carried out, if the requirement of the consensus mechanism is met, the preset condition is determined to be met, and the received content can be stored in the account book of the current node.
By the arrangement, when the current node does not have relevant transaction information, the relevant transaction information can be obtained through recalculation. By the arrangement, network connection between the client and other nodes can be avoided while the safety of transaction information is ensured, and the method is efficient and easy to implement.
In this aspect, optionally, before initiating a transaction information acquisition request to other nodes of the blockchain through the current node, the method further includes:
determining a maximum transaction number currently generated in the blockchain;
and if the transaction number of the transaction inquiry request is smaller than the maximum transaction number, determining that the phenomenon of transaction information missing exists in the current node.
In the scheme, the relation between the transaction number which is required to be obtained currently and the largest transaction number in the blockchain or the relation between the number segment to which the transaction number which is required to be obtained currently belongs and the largest transaction number can be determined by acquiring the request sent by the client. If the transaction number is smaller than the maximum transaction number, determining that the phenomenon of transaction information missing exists in the current node. The cause of the transaction information loss phenomenon may be network disruption, power outage, or other more complex cause for the current node. Through the arrangement, the method and the device can assist in determining whether the current node operates stably or not, and meanwhile, the accurate and effective transaction information can be ensured when the returned transaction information is processed.
In the above solution, optionally, after determining that the current node has the transaction information missing phenomenon, the method further includes:
And determining a missing number segment according to all transaction number ranges stored in the account book of the current node, and determining a transaction information acquisition request based on the missing number segment.
After the phenomenon of missing transaction information occurs, the missing number segment can be determined according to the transaction number range stored in the account book. For example, if each hash value is generated in a batch of 2000, the missing number segment range may be determined according to the number segment range of the transaction information stored in the ledger, for example, if two number segments are found to be missing, a transaction information acquisition request may be further generated based on the missing number segments, so as to broadcast the request to other nodes.
By the arrangement, the method and the device can search the range of the local real number segment together and complement the result returned by other nodes while returning the transaction information, thereby being beneficial to the subsequent response capability of searching the transaction information of the current node.

Fig. 3 is a functional schematic diagram of a module in a query process of a blockchain transaction in the third embodiment of the present invention, as shown in fig. 3, each module may cooperate and have the following functions:
The block generation module:
a unique, continuous ID is generated for each transaction in the block, which requires continuous self-increment. For example, if the last transaction in the previous block has an ID of 3344, the transaction ID of the current block starts from 3345.
A transaction set Hash algorithm generation module:
judging whether the latest transaction number N meets a certain condition (for example, whether N is equal to a specific value or the remainder is equal to a certain value), and if so, carrying out a Hash algorithm calculation flow.
Calculating a Hash value H1 for a transaction of a specified transaction number, and signing the Hash value and a transaction ID range by using the node key to obtain a signature value Sign1, wherein a signature original is formed, including but not limited to a format of hash=xxx & idbegin=xxx & idend=xxx.
Hash result broadcasting and receiving module:
and broadcasting the generated Hash value H1, ID range and signature information Sign1 to other nodes of the block chain network, and simultaneously receiving H1, ID range and Sign1 broadcasted by other nodes.
The Hash result processing module:
the Hash value H1, the ID range and the signature information Sign1 are stored in the blockchain ledger L1, and when the collected results are consistent and exceed a certain proportion from the blockchain network, the result is marked as a final result.
The scheme provides inquiry capability for the client, and the client can inquire whether the transaction exists in the blockchain ledger L1 according to the transaction ID number. When a certain ID range is always in a missing state, hash calculation, signature and broadcasting flow of the certain ID range can be restarted in the blockchain network.
Specifically, the blockchain transaction inquiry method comprises three sub-processes, and the three sub-processes use the modules to cooperatively finish the transaction inquiry method of the scheme:
1. and generating a query result flow.
Fig. 4 is a schematic diagram of a flow of generating a query result in the third embodiment of the present invention, as shown in fig. 4, mainly including the following steps:
step 1, the new generation block contains a large number of transactions, the transaction ID of the last number is obtained, the preset condition is met, the next flow is entered, and otherwise, the process is not carried out.
And 2, after meeting the conditions, carrying out Hash calculation on all transactions from the last transaction ID of the last calculation Hash to the last transaction ID of the current calculation Hash to generate a Hash result H1, and signing the H1 and the transaction ID range by using a node secret key.
And 3, broadcasting the Hash result H1, the transaction ID range and the transaction signature to other nodes.
And 4, the node receives the transaction results broadcast by other nodes.
And 5, the node stores and compares the transaction result information broadcast by each node, and if the data of each node is consistent and exceeds a certain node number, the node indicates that the data result is consistent. And records the result to the ledger.
2. The client queries the transaction flow.
Fig. 5 is a schematic diagram of a client query transaction flow in the third embodiment of the present invention, as shown in fig. 5, mainly including the following steps:
step 1, a client queries a certain transaction detail information according to a transaction number.
And 2, searching the node account information by the Hash result processing module, and storing a consistency result. And if the Hash calculation result broadcast by each node exists, sending the Hash calculation result broadcast by each node to the client.
And step 3, if the account book does not exist, initiating a process of generating the query result, acquiring the query result and sending the query result to the client.
3. Hash generation retry flow.
Fig. 6 is a schematic diagram of a Hash generation retry flow in the third embodiment of the present invention, if a node is disconnected, the broadcasted Hash result information may be missed. Therefore, the scheme provides a retrieval mode of the Hash result. As shown in fig. 6, mainly comprises the following steps:
step 1, if the number of the last transaction of the current highest block is M, but the Hash result with the ID of p-q range is lacking locally.
And 2, broadcasting a Hash result generation request to other nodes by the node.
And step 3, after receiving the request, other nodes execute a Hash generation flow and send a Hash result to the requesting node. The request node receives the Hash results of all the nodes, and if the Hash results are consistent and exceed a certain proportion, the results are considered to be consistent.
By the arrangement, the transaction information can be quickly and efficiently inquired. The transaction hash generation flow is executed once every N transactions, and the multi-party inquiry is not performed by the transaction inquiry request, and only the transaction result condition of the node is required to be inquired when the transaction inquiry request is issued, so that the transaction inquiry time is shortened, and the inquiry efficiency is improved. In addition, the scheme can solve the problem of complex network limitation, does not need a client to access all the blockchain nodes for inquiring, ensures consistency of inquiry results and prevents Bayesian attack. In addition, the scheme stores ID information, hash information and signature information of the transaction set, transaction content and query requests are not required to be stored, and meanwhile, a plurality of transaction IDs generate one Hash and signature, so that the storage space is less in loss.
