Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it should be understood that the described embodiments are a part of the embodiments of the present application, and not all of the embodiments, and the present application is not limited by the embodiments described below.
In the specification and drawings, elements are described in singular or plural according to embodiments. However, the singular and plural forms are appropriately selected for the proposed cases only for the sake of explanation without intending to limit the present application thereto. Thus, the singular may include the plural and the plural may also include the singular, unless the context clearly dictates otherwise.
Embodiments of the present application relate to blockchain and cross-chain technologies, and some concepts related to the embodiments of the present application will be described below for the sake of understanding.
Block chains: the block chain data structure takes blocks (blocks) confirmed by a consensus mechanism as basic units, data in the block chain are distributed in the blocks which are connected in time, the Hash (Hash) value of the previous block is recorded in the next block, whether each block (and transaction in the block) is legal or not can be quickly checked in a way of calculating the Hash value, and the block chain data structure has the characteristics of being not falsifiable, open and transparent.
And (3) deposit and certificate transaction: the real data generated by the physical world by the nodes in the block chain can be constructed into a standard transaction format supported by the block chain, then the real data is issued to the block chain, the received transaction is subjected to consensus processing by the nodes in the block chain, after consensus confirmation is achieved, the transaction is packaged (namely stored) into the block by the accounting nodes in the block chain, and persistent evidence is stored in the block of the block chain.
Accounting node/mining node (validator/miner): the nodes participating in consensus in the blockchain contribute strength to achieving consensus.
Consensus: typical consensus mechanisms of the algorithms for achieving consistency in the distributed system include proof of work (pow), proof of stop (pos), Byzantine Fault Tolerance (BFT), and the like.
And (3) hash value: also called information characteristic value or characteristic value, a hash value is generated by converting input data of an arbitrary length into a password by a hash algorithm and fixedly outputting, and original input data cannot be retrieved by decrypting the hash value, which is a one-way encryption function. In a blockchain, each block (except the original block) contains the hash value of the previous block, which is referred to as the parent block of the current block. Hash values are the core foundation and most important aspect of the potential in blockchain technology, which preserves the authenticity of the record and view data, as well as the integrity of the blockchain as a whole.
And (3) chain crossing: and the communication among different block chains is realized through intermediate equipment such as a cross-chain gateway, a cross-chain relay and the like. Fig. 1 is a schematic structural diagram of a chain crossing system, which includes: a blockchain 10 constructed from a number of nodes 12 (illustrated as 3), a blockchain 20 of a number of nodes 22 (illustrated as 3), a cross-chain gateway 11 that can communicate with nodes 12 in blockchain 10, and a cross-chain gateway 21 that can communicate with nodes 22 in blockchain 20. The cross-chain gateway 11 is connected with the cross-chain gateway 21 in a communication mode. In the cross-chain system, any node 12 of the blockchain 10 can participate in consensus verification of the blockchain 10, synchronize a shared book of the blockchain 10, and communicate with the cross-chain gateway 11 at an application layer, and communicate with a certain node or nodes of the blockchain 20 through the cross-chain gateway 11 and the cross-chain gateway 21. Similarly, any node 22 of the blockchain 20 may participate in consensus verification of the blockchain 20, synchronize the shared book of the blockchain 20, and communicate with the cross-chain gateway 21 at the application layer, and communicate with one or some nodes of the blockchain 10 through the cross-chain gateway 21 and the cross-chain gateway 11. The application layer is a layer isolated from the block chain underlying technology, belongs to the application layer of computer software, and can also be called as an application entity (abbreviated as "AE"), and is composed of a plurality of specific application service elements (abbreviated as "SASE") and one or more common application service elements ("CASE"), and provides specific application services for the SASE.
It should be noted that the structure of the cross-chain system shown in fig. 1 is merely an illustration, and does not constitute a structural limitation of the cross-chain system applied in the present application.
Fig. 2 is a schematic flow chart of a cross-link evidence storing method provided in the present application, including:
in this embodiment of the present application, a cross-link credentialing device (for example, a cross-link gateway) connected to a target blockchain may monitor a credentialing transaction on the target blockchain, specifically, step 101 may include: monitoring whether a new evidence storing transaction is stored in a block (namely, a block of the target block chain) of the target block chain, determining to monitor the evidence storing transaction on the target block chain when the new evidence storing transaction is stored in the block of the target block chain, and otherwise, immediately or after waiting for a preset time, continuing to execute the monitoring action of the step 101.
In practical applications, one cross-chain evidence storing device may connect one or more than two blockchains, and when the cross-chain evidence storing device connects only one blockchain, the blockchain may be used as a target blockchain by default to execute the cross-chain evidence storing method shown in fig. 2. When the inter-chain evidence storing device connects more than two block chains, each block chain connected with the inter-chain evidence storing device can be used as a target block chain, so as to respectively execute the inter-chain evidence storing method shown in fig. 2 for each target block chain; alternatively, the inter-chain evidence storing device takes some, or all of the blockchains connected to the inter-chain evidence storing device as the target blockchain based on the setting or indication of the user, which is not limited herein.
when the evidence storing transaction on the target block chain is monitored, further judging whether the monitored evidence storing transaction meets a preset cross-chain evidence storing condition, if so, executing the step 103; otherwise, step 103 is not executed, and the process returns to step 101 immediately or after waiting for a preset time.
In this embodiment of the application, the determination action performed in step 102 may be performed by the cross-chain evidence storing device, or may also be triggered by the cross-chain evidence storing device to perform and acquire a determination result of another device in communication connection therewith, which is not limited herein.
103, performing cross-link evidence storing processing on the evidence storing transaction so as to store the relevant information of the evidence storing transaction into a block chain linked with the target block chain;
in this embodiment, the evidence storing transaction may be stored in any block chain or any plurality of block chains linked to the target block chain through cross-chain evidence storing processing, or the evidence storing transaction may be stored in a default block chain linked to the target block chain through cross-chain evidence storing processing, or the evidence storing transaction may be stored in a block chain linked to the target block chain and associated with the cross-chain evidence storing condition through cross-chain evidence storing processing, which is not limited herein. Two application scenarios provided by the present application are further explained below:
in one application scenario, the cross-chain warranty condition is associated with at least one blockchain. Step 103 may be embodied as: and performing cross-chain evidence storage processing on the evidence storage transaction based on the block chain associated with the preset cross-chain evidence storage condition so as to store the related information of the evidence storage transaction into the block chain which is linked with the target block chain and is associated with the preset cross-chain evidence storage condition. For example, if the target blockchain is set as blockchain a, the preset cross-chain evidence storing condition is associated with blockchain B and blockchain C, and blockchain a is linked with blockchain B and blockchain C, respectively, in step 103, the evidence storing transaction can be stored into blockchain B and blockchain C from blockchain a in a cross-chain manner.
In another application scenario, one or more block chains linked to the target block chain may be set as a default block chain, and step 103 may be specifically expressed as: and performing cross-link evidence storage processing on the evidence storage transaction based on a default block chain linked with the target block chain so as to store the relevant information of the evidence storage transaction into the default block chain. For example, if the target block chain is a block chain a, the block chain B and the block chain C are respectively linked with the block chain a, and the block chain B is set as a default block chain, in step 103, the deposit transaction may be stored in the block chain B from the block chain a in a chain-crossing manner.
It can be seen from the above that, the technical scheme of this application is through monitoring the deposit certificate transaction on the target block chain, when the deposit certificate transaction that monitors satisfies the preset cross-chain deposit certificate condition, deposit certificate transaction to this and cross the chain and deposit certificate processing to this has realized the automation of cross-chain deposit certificate, because whole process need not the user additionally to initiate and cross the chain and deposit certificate request, so can improve the efficiency of cross-chain deposit certificate to a certain extent.
In this embodiment of the present application, the cross-chain evidence storing condition may be set by a user in a customized manner, for example, the cross-chain evidence storing condition may be: if the evidence storing transaction is related to a designated company (e.g., company C1), in step 102, determining whether the monitored evidence storing transaction on the target block chain is related to the designated company, if so, determining that the determination result is satisfied (i.e., the monitored evidence storing transaction satisfies a preset cross-link evidence storing condition), otherwise, determining that the determination result is not satisfied (i.e., the monitored evidence storing transaction does not satisfy the preset cross-link evidence storing condition); alternatively, the cross-chain evidence storing condition may be: if the evidence storing transaction occurs in a specific time period and is related to a designated company, in step 102, judging whether the monitored evidence storing transaction on the target block chain occurs in the specific time period and is related to the designated company, if the evidence storing transaction occurs in the specific time period and is related to the designated company, determining that the judgment result is satisfied, otherwise, determining that the judgment result is not satisfied; alternatively, the cross-chain evidence storing condition may be: if the block height of the block related to the evidence storing transaction is within the preset block height interval, in step 102, determining whether the monitored block height of the block related to the evidence storing transaction on the target block chain is within the block height interval, if so, determining that the determination result is satisfied, and if not, determining that the determination result is not satisfied; alternatively, the cross-chain evidence storing condition may be: if the block height of the block related to the evidence storing transaction is within the preset block height interval and is related to the designated company, in step 102, it is determined whether the monitored block height of the block related to the evidence storing transaction on the target block chain is within the block height interval and is related to the designated company, if so, the determination result is determined to be satisfied, and if not, the determination result is determined to be not satisfied.
In practical application, a user can trigger the update of the cross-chain evidence storing condition by sending cross-chain update information. Specifically, on the basis of the cross-chain evidence storing method shown in fig. 2, as shown in fig. 3, the cross-chain evidence storing method further includes:
wherein the cross-chain update information includes: block height and cross-link warranty conditions.
In the embodiment of the present application, an application programming interface (i.e., API interface) for updating the cross-link evidence storing condition may be provided for the user, and the API interface needs to specify two parameters: cross-chain warranty conditions and block height. The user may input a new cross-link warranty condition and a block height through the API interface to generate cross-link update information, so that step 201 receives the cross-link update information input based on the API interface.
in the embodiment of the application, when the block height of the target block chain reaches the block height in the cross-chain updating information, updating of the cross-chain evidence storing condition is triggered, that is, a preset cross-chain evidence storing condition is updated to the cross-chain evidence storing condition in the cross-chain updating information, and then the monitored evidence storing transaction is judged and screened according to the updated cross-chain evidence storing condition.
It should be noted that step 201 and step 202 may occur before or after any of the steps shown in fig. 2, that is, the user may trigger the update of the cross-chain evidence storing condition by inputting the cross-chain update information at any time.
In the embodiment of the application, by setting the chain-crossing evidence storage condition, a user can control data needing chain-crossing evidence storage in a finer granularity, and waste caused by chain-crossing of useless data can be reduced to a certain extent. And the hot update of the cross-chain evidence storage condition can be carried out on the premise of not restarting equipment (such as a cross-chain gateway device), so that the method is more friendly to users.

Then, the user U1 initializes the cross-chain gateway 1 for cross-chain credentialing transfer, and during the initialization, the initialized cross-chain credentialing condition can be specified by configuration, and then the cross-chain gateway 1 is started.
When the evidence storing transaction monitored by the cross-link gateway 1 meets the currently set cross-link evidence storing condition, the cross-link gateway 2 performs cross-link evidence storing processing on the evidence storing transaction, so that the related information of the stored transaction is stored in the block chain B.
Further, the cross-link gateway 1 provides an API interface for updating the cross-link credential condition. User U1 needs to update the cross-link credential condition at some point, either for business or other reasons. User U1 inputs a new cross-chain credit condition F' and tile height H by re-entering the API interface to generate cross-chain update information. And when the block height of the block chain A reaches the block height H, the cross-chain gateway updates the current cross-chain evidence storing condition F to F ', and then the evidence storing transaction occurring on the block chain A is screened according to F'.
