The invention provides an information query method.

Referring to Figure 2, Figure 2 is a schematic flow chart of the first embodiment of the present invention.

In a first embodiment, the method may include:

S10: When receiving the query command, parse the query command and obtain the target Hash;

This step aims to parse the query instructions to obtain the target Hash. Specifically, when the user needs to query data interaction information, he or she can input a query instruction based on the corresponding terminal device. The query instruction is appended with the Hash value of the data interaction information that the user needs to query, that is, the above-mentioned target Hash. Among them, the target Hash is generated when both parties perform data interaction to generate data interaction information. Each piece of data interaction information has its unique corresponding Hash, which is equivalent to the unique identification of the data interaction information. Therefore, it can be implemented based on Hash Query corresponding data interaction information. Furthermore, by parsing the obtained query instructions, the target Hash can be obtained. For the specific implementation process of the parsing operation, please refer to the existing technology, which will not be described in detail here.

S11: Use the target Hash to retrieve the corresponding target data interaction information;

This step aims to obtain the target data interaction information. The target data interaction information is the data interaction information that the user needs to query, that is, the data interaction information corresponding to the target Hash. Since each piece of data interaction information has and has only one corresponding Hash , therefore, the corresponding target data interaction information can be obtained based on the target Hash. Specifically, when the two parties perform data interaction and generate target data interaction information, the target data interaction information can be stored in the corresponding storage space together with the corresponding generated target Hash. Thus, the target Hash is obtained based on the query instruction. Then, the corresponding target data interaction information can be queried from the storage space according to the target Hash. The specific type of data interaction information does not affect the implementation of this technical solution. This application does not specifically limit this. For example, it can be transaction information generated during a refund transaction on the blockchain, etc.

Preferably, the above method of using the target Hash to retrieve the corresponding target data interaction information may include: using the target Hash to retrieve the target data interaction information in a KV storage database (Key-Value, key-value storage database).

The embodiment of this application provides a more specific storage method for various types of data information, that is, data storage based on KV storage database, that is, each data interaction information and its corresponding hash and index information are correspondingly stored in the KV storage database. Among them, the KV storage database is a NoSQL (non-relational database) model, in which data information can be organized, indexed and stored in the form of key-value pairs, and has high read and write performance.

Preferably, the above-mentioned use of the target Hash to retrieve the target data interaction information in the KV storage database may include: parsing the query instructions to obtain the target interaction type of the target data interaction information; in the KV storage database, using the target Hash to retrieve the target data interaction information in the KV storage database. The target data interaction information is retrieved from the target storage path corresponding to the type.

Specifically, various types of data information can be classified and stored in the KV storage database. For example, transfer data information and refund data information are stored in different storage paths respectively, or data interaction information of different types of customers are stored in different storage paths respectively. Next, further, the query command input by the user may also include target interaction type information, so as to determine the target interaction type corresponding to the target data interaction information through data analysis, and then retrieve the target data interaction information from the corresponding target storage path.

S12: Obtain the target index information corresponding to the target data interaction information; wherein, the target index information includes the data interaction source identifier and the lower-layer data interaction identifier;

This step aims to achieve the acquisition of target index information, which corresponds to the target data interaction information. Specifically, when the target data interaction information is generated, target index information can be created for it, including the data interaction source identifier and the underlying data interaction identifier corresponding to the target data interaction information; further, during the information storage process, the target index information The target data interaction information and the target Hash are correspondingly stored in the storage space. Therefore, after obtaining the target data interaction information, the corresponding target index information can be obtained quickly and conveniently. Among them, the data interaction source identifier is the relevant identification information of the upper-layer data interaction information corresponding to the target data interaction information, and the lower-layer data interaction identifier is the relevant identification information of the lower-layer data interaction information corresponding to the target data interaction information. Based on this identification, it can be conveniently and quickly queried. to other data interaction information related to the target data interaction information.

S13: Use the data interaction source identifier and the underlying data interaction identifier to query to obtain all data interaction information related to the target data interaction information.

This step aims to implement the query of data interaction information, that is, to obtain all data interaction information related to the target data interaction information based on the query of the data interaction source identifier and the underlying data interaction identifier. Taking transaction information query as an example, after obtaining the target transaction information by specifying the Hash and obtaining the corresponding target index information, the parent transaction information that generated the target transaction information (corresponding to the target data interaction generated) can be obtained based on the data interaction source identifier. The upper-layer data interaction information of the information), based on the lower-layer data interaction identifier, the sub-transaction information generated by the target transaction information is obtained (corresponding to the lower-layer data interaction information generated by the target data interaction information), thus, all transactions with the target can be obtained All transaction information related to the information ensures the integrity of the transaction information.

As a preferred embodiment, each data interaction terminal that generates each data interaction information is a node that forms a blockchain network, and each data interaction terminal is deployed in different partitions of the blockchain network.

Specifically, the data interaction information is generated by the data interaction terminal. In the embodiment of the present application, each data interaction terminal can be a node that forms a blockchain network to realize data interaction on the blockchain chain; further , each data interaction terminal can be deployed in different partitions of the blockchain network in the blockchain network. Specifically, the regions can be divided according to their own address information, etc., thus enabling intra-partition data interaction and cross-partition data interaction. Among them, cross-partition data interaction can be divided into cross-in data interaction and cross-out data interaction, thereby realizing various forms of data interaction based on data interaction terminals.

The information query method provided by this embodiment establishes corresponding index information in advance when the data interaction information is generated. In addition, each piece of data interaction information will generate a corresponding Hash when it is generated. When storing the information, the three can be Stored correspondingly to each other, therefore, when performing information query, the corresponding data interaction information can be queried based on the specified Hash, and then the index information can be obtained, because the index information includes the data interaction source identifier corresponding to the data interaction information and the lower layer Data interaction identifier, therefore, all data interaction information related to the data interaction information can be queried based on the data interaction source identifier and the underlying data interaction identifier; further, when transaction information is queried based on this information query method, it can be queried based on The specified transaction information is queried to find all transaction information associated with the transaction information, including the parent transaction information that generated the transaction information and the child transaction information generated by the transaction information, effectively ensuring the integrity of the transaction information query results.

The invention provides an information storage method.

Referring to Figure 3, Figure 3 is a schematic flow chart of a second embodiment of the present invention.

In a second embodiment, the method may include:

S20: When the data interaction information is obtained, index information is established for the data interaction information; where the index information includes a data interaction source identifier and a lower-layer data interaction identifier;

S21: Obtain the Hash of the data interaction information, and store the data interaction information, index information and Hash correspondingly to the preset storage space.

Based on the information query method of the previous embodiment, this embodiment of the present application introduces in detail the storage process of each data interaction information.

Specifically, after the data interaction terminal generates data interaction information through data interaction, corresponding index information can be directly established for it, and its corresponding Hash can be generated at the same time, and then the data interaction information, index information and Hash can be correspondingly stored in a pre-established In the storage space, that is, the above-mentioned default storage space. Among them, the above-mentioned index information established for the data interaction information may include a data interaction source identifier and a lower-layer data interaction identifier. Furthermore, during subsequent information query, a certain generated data can be queried in the preset storage space based on the data interaction source identifier. Various types of upper-layer data interaction information of data interaction information, and various types of lower-layer data interaction information generated by querying the data interaction information according to the lower-layer data interaction identification. Therefore, all the data related to the data can be queried based on the index information based on the data interaction information. All data interaction information related to interaction information.

Furthermore, based on the above information storage method, transaction information is stored, and all transaction information with associated relationships can be easily queried using index information, achieving high efficiency in transaction information query, and making later reconciliation more convenient.

The present invention provides a more specific information query method. This embodiment takes the storage and query of transaction information as an example. The specific implementation process is as follows:

First, for each transaction information generated by both parties to the transaction, that is, the above-mentioned data interaction information, corresponding index information can be established. For example, the structure of the index information can be of the following type (not unique):

Among them, TxEntry is the index information. The index information includes block Hash, block height, transaction source, transaction partition, transaction sorting position in the block, and sub-transaction array. Among them, the sub-transaction array ChildTxs is the above The underlying data interaction identifier may include one or more sub-transactions ChildTx;

Among them, the transaction source TxRole is the above-mentioned data interaction source identifier, which can specifically include: this partition initiates TxLocal, other partitions cross into TxCrossIn, and this partition crosses into other partitions TxCrossOut;

Among them, the Zone ID of the exchange is specifically: the outgoing transaction is the zone ID where the To address is located, the incoming transaction is the zone ID where the parent exchange is located, and the local transaction is the zone ID where the From address is located;

Among them, ChildTx can specifically include the following information:

TxType (sub-transaction type, identifying RefundTx, ContractTx and other types of sub-transactions)

TxHash (sub-transaction Hash)

ZoneID (the zone ID where the sub-exchange is located)

In addition, for the above TxRole, if a transaction Tx, its transfer address (From address) is divided into the current zone (assumed to be Zone0), and the receiving address (To address) is divided into another partition (assumed to be Zone1), then The transaction Tx can be packaged into a new transaction Tx1 (the Hash is different from the Hash of Tx) and forwarded to Zone1. The TxRole of Tx in Zone0 is TxLocal, and the TxRole of the generated Tx1 is TxCrossOut, which means that Tx1 is to be executed in Zone1. The TxRole of Tx1 on Zone1 is TxCrossIn, which means that Tx1 is executed from the Zone0 partition to Zone1; if the From address and To address of a transaction are both in the current partition, the TxRole is TxLocal, and no additional cross-partition transactions are generated.

Furthermore, you can also construct the TxEntryHash of the index information based on the TxHash of the transaction, and then store the index information in KV (TxEntryHash->TxEntry). Of course, just store the corresponding transaction information and its hash in the KV storage database at the same time.

Further, please refer to Figure 4. Figure 4 is a flow diagram of a cross-zone transaction in a blockchain provided by the present invention. Specifically, a transaction Tx01 on zone0 (packaged in block Block0 of zone0) needs to be cross-zone. Execute on zone1, convert it to Tx on zone0 and send it to zone1 for execution (packaged in Block1 of zone1). The originHash of Tx is Hash (Tx01); after the execution of Tx, the unconsumed gas will be returned to the Tx01 transaction. The initiator generates a RefundTx for gas refund and executes it on zone0. The originHash of the RefundTx is Hash(Tx). Correspondingly, index information is created for the corresponding transactions on the respective partitions:

1. Transaction index on Zone0:

(1) TxEntry of Tx01:

{TxRole:TxRoleLocal, ZoneID:0, ChildTx:{TxHash:Hash(Tx), ZoneID:1}}

It can be seen that the main index information is Block0Hash, Block0Height, ZoneID is 0, TxRole=TxLocal, and the information that generates a sub-transaction Tx is: TxHash=Hash(Tx), ZoneID=1, which specifically means that Tx01 is packaged in partition 0 Block0 of Block0 contains a transaction Tx that needs to be executed in partition 1;

(2) TxEntry of Tx:

{TxRole:TxRoleCrossOut, ZoneID:1, ChildTx:[]}

It can be seen that the main index information is Block0Hash, Block0Height, ZoneID is 1, TxRole = TxCrossOut, which specifically means that Tx needs to go out to partition 1 for execution;

(3)TxEntry of RefundTx:

{TxRole:TxRoleCrossIn, ZoneID:1, ChildTx:[]}

It can be seen that the main index information is that ZoneID is 1 and TxRole=TxCrossIn, which specifically means that RefundTx crosses from partition 1 to partition 0;

2. Transaction index on Zone1:

(1) TxEntry of Tx:

{TxRole:TxRoleCrossIn, ZoneID:0, ChildTx:{TxHash:Hash(RefundTx), ZoneID:0}}

It can be seen that the main index information is Block1Hash, Block1Height, ZoneID is 0, TxRole=TxCrossIn, and the information that generates a sub-transaction RefundTx is: TxHash=Hash (RefundTx), ZoneID=0, specifically indicating that Tx is entered from partition 0. Partition 1, and is packaged in Block 1 of partition 1, and the transaction generates a RefundTx that needs to be crossed back to partition 0;

(2) TxEntry of RefundTx:

{TxRole:TxRoleCrossOut, ZoneID:0, ChildTx:[]}

It can be seen that the main index information is Block1Hash, Block1Height, ZoneID is 0, TxRole=TxCrossOut, which specifically means that RefundTx crosses from partition 1 to partition 0.

In this way, when querying transaction information later, without changing the original transaction, the transaction information and the index information of the transaction can be quickly obtained based on the transaction type and transaction Hash, and then the parent transaction corresponding to the transaction information can be found based on the index information. Information, transaction source partition, block information of the partition, generated sub-transaction information, etc., that is, all transaction information related to this transaction is deduced, which is more convenient for development, testing and reconciliation of transactions in the production environment. , query and other needs.

It can be seen that the information query method provided by this embodiment establishes corresponding index information in advance when the data interaction information is generated. In addition, each piece of data interaction information will generate a corresponding Hash when it is generated. When the information is stored, it can be The three are stored corresponding to each other. Therefore, when performing information query, the corresponding data interaction information can be queried based on the specified Hash, and then the index information can be obtained, because the index information includes the data interaction source identifier corresponding to the data interaction information. and the lower-layer data interaction identifier. Therefore, all data interaction information related to the data interaction information can be queried according to the data interaction source identifier and the lower-layer data interaction identifier; further, when the transaction information is queried based on this information query method, that is All transaction information associated with the transaction information can be queried based on the specified transaction information, including the parent transaction information that generated the transaction information and the child transaction information generated by the transaction information, effectively ensuring the integrity of the transaction information query results.
