Detailed Description
Currently, in a federation chain application, data update issues between heterogeneous chains may be involved. For example, a chain a and a chain b are two heterogeneous chains in a federation chain, the two chains involve exchange of cross-chain data, the chain a needs to read partial information of the chain b, and the chain b needs to synchronize key information on the chain a. In some application scenarios, some information needs to be stored on both chain a and chain b, and the information needs to be kept consistent, and the information needs to be updated timely in order to keep the information consistent. If the asset transaction occurs in the chain a and the asset is transferred from one child node of the chain a to another child node of the chain a, the information needs to be updated synchronously on the chain b, and it is ensured that the information of the assets on the two chains is consistent and not tampered, the synchronous operation can be completed in time, and the situation that the transaction occurs in the chain a and the b cannot be synchronized cannot occur.
In the related technology, the notary node can be used for reading and writing data to complete the operation, if the notary completely reads and writes information to the heterogeneous chains, the problem of different data formats or different data processing interfaces exists between the heterogeneous chains, and the problem can be solved by the notary node being compatible with different data formats.
The notary node can usually select a third party which is trusted by each chain in the heterogeneous chain, and mainly plays a role of trusting the third party in data interaction; in one embodiment, the notary node may select a regulatory agency or related department.
In the process of synchronizing the data between the heterogeneous chains by the notary node, the notary node reads the data needing synchronization from one chain in the heterogeneous chains, and then synchronously writes the data into all nodes in the other chain in the heterogeneous chains. When the notary node synchronizes data between heterogeneous chains, the notary node needs to synchronously write the data into all nodes in another chain in the heterogeneous chains at the same time, which consumes long time and has high data throughput, resulting in low data reading and writing efficiency.
Therefore, the federation chain data processing method, the apparatus and the electronic device provided in the embodiment of the application ensure the final consistency of data through a data asynchronous updating method in a federation chain, and compared with a method for reading and writing data by a notary node in the related art, the method has lower performance requirements on the notary node, does not need the notary node to simultaneously store and read and write a large amount of information, can enable a node of a sub-chain to update data through a consensus algorithm, and keeps the data consistency of nodes in the sub-chain, and can achieve the final consistency state of data without synchronous writing operation of the notary node, and can ensure the safety and consistency of data with smaller calculation power. Asynchronization allows for possible data inconsistencies between chains and nodes in a federation chain system shortly after a transaction occurs, but the data will be guaranteed to be consistent after the transaction is completed.
Based on this, an embodiment of the present application provides a method and an apparatus for processing federation chain data, and an electronic device, where a notary node sends transfer information of resource information sent by a resource information receiving node to a write-in node of a sub-chain where the resource information is transferred, and updates a state of the resource information recorded on a node located on the same sub-chain as the write-in node through the write-in node, so that the state of the resource information recorded on a node located on the same sub-chain as the write-in node is updated through the write-in node, and it is not necessary for the notary node to write data into all nodes in the sub-chain synchronously at the same time, thereby reducing processing time of the notary node and improving read-write efficiency of the data.
For better explanation of the embodiments of the present application, first, the following description is made on an application scenario of a federation chain data processing method, an apparatus, and an electronic device provided in the embodiments of the present application:
the alliance link data processing method and device and the application scene of the electronic equipment provided by the embodiment of the application comprise the following steps: notary nodes and individual child chains in a federation chain.
Data interaction and updating are carried out among the heterogeneous chains through cross-chain nodes, and the consistency of the data among the heterogeneous chains is kept.
The cross-link node is used for representing a node which becomes a node of a heterogeneous chain of the sub-chain in the sub-chain.
Typically, node types and functions across chain nodes are consistent across heterogeneous chains. That is, when the node type of the node on the sub-chain is an uploading node, the node type of the node in the heterogeneous chain of the sub-chain should also be an uploading node, and the function of the uploading node in the heterogeneous chain of the uploading node is the same as the function of the uploading node on the sub-chain.
In the following embodiments of the present application, the data refers to resource information, and the resource information may be, but is not limited to: digital currency, virtual currency, or points.
When the resource information is transferred from one node of the sub-chain to another node in a transfer mode, the node from which the resource information is transferred out of the sub-chain is called a resource information sending node; the node to which the resource information on the child chain is transferred is called a resource information receiving node.
In the transfer process, only the transfer on the amount of the resource information exists, and the type of the resource information does not change in the transfer process.
The notary node, the resource information sending node, the resource information receiving node and other nodes in the alliance chain can all use a server.
The server may adopt any computing device capable of processing the alliance link data and maintaining data consistency in the prior art, which is not described in detail herein.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Example 1
Referring to a flowchart of a federation chain data processing method shown in fig. 1, the present embodiment provides a federation chain data processing method, including the following specific steps:
In step 100, the transition information and the status information of the resource information transmitted by the resource information receiving node are generated by the resource information transmitting node.
In order to generate the transition information and the state information of the resource information, the resource information transmitting node may perform the following steps (1) to (6):
(1) acquiring a resource information transfer command, wherein the resource information transfer command comprises: the second identification and the resource information transfer quantity;
(2) acquiring the first identifier and the data updating time length, and generating transfer information of the resource information by using the first identifier, the data updating time length, the second identifier and the transfer quantity of the resource information; signing the transfer information of the resource information by using the private key of the resource information sending node to obtain the transfer information of the resource information signed by the resource information sending node;
(3) updating the state of the resource information after the resource information transfer according to the first identifier, the second identifier and the resource information transfer number to obtain the updated state of the resource information, storing the updated state of the resource information in a block of the subchain where the resource information sending node is located, and acquiring the state information of the resource information in the current transfer period, wherein the state information of the resource information in the current transfer period comprises: the resource information transfer times of the subchain where the resource information sending node is located in the current transfer period, the transfer period identifier of the current transfer period and the block height;
(4) performing increment operation on the block height to obtain the block height after the increment operation, and performing update operation on the resource information transfer times to obtain updated resource information transfer times;
(5) generating state information of the resource information by using the transfer cycle identifier of the current transfer cycle, the block height after incremental operation and the updated resource information transfer times;
(6) and sending the transfer information and the state information of the resource information to a resource information receiving node, wherein the resource information receiving node signs the transfer information of the resource information by using a private key of the resource information receiving node to obtain the transfer information of the resource information with the signature of the resource information sending node and the signature of the resource information receiving node, and sends the state information of the resource information and the transfer information of the resource information after the signature to a notary node.
In the step (1), the resource information transfer command is triggered by a worker of the resource information sending node, and the worker inputs the second identifier, the resource information transfer number, and the address of the resource information receiving node to the resource information sending node.
The second identifier is used for representing the identifier of the resource information receiving node.
In the step (2), the first identifier and the data update duration are cached in the resource information sending node.
The first identifier is used for representing an identifier of a resource information sending node.
The data update duration is a piece of information of the data description cached in the resource information sending node.
And the data updating time length is used for indicating the time length of the asynchronous updating of the data by the nodes in the alliance chain. The initial time of the data updating time is the time point of the notary node broadcasting the transfer information of the resource information, the termination time is the set updating time, the data is not consistent after termination, and the transaction is determined to be invalid.
The data update duration may be set to any time length between 30 seconds and 100 seconds, and in one implementation, the data update duration may be set to 60 seconds.
In one embodiment, the first identifier is Ws(ii) a The second mark is Wd(ii) a The number of resource information transfers is 20; the data update duration is 60 seconds. The generated resource information should include the above four parameters.
And the private key of the resource information sending node is cached in the resource information sending node and is allocated to the resource information sending node by the main node of the alliance chain. The specific process of performing signature operation on the resource information by using the private key of the resource information sending node to obtain the transfer information of the resource information with the signature of the resource information sending node is the prior art, and is not described herein again.
In one embodiment, the resource information sending node signature may be 0 xAA.
In the step (3), the state information of the resource information in the current transfer period is used to record the state of the resource information after the last resource information transfer of the sub-chain where the resource information sending node is located.
The transfer period may be a time length in days, weeks, or months. When the transfer period is a unit time length of day, each day is a transfer period.
Therefore, the transfer period needs to be updated. When the transfer period changes, the notary node broadcasts a transfer period identifier in the alliance chain to update the transfer period of the alliance chain.
After each node in the alliance chain receives the transfer period identifier broadcast by the notary node, the received transfer period identifier is used for replacing the transfer period identifier stored by the node, and therefore the transfer period is updated.
In order to update the state of the resource information after the resource information transfer according to the first identifier, the second identifier and the resource information transfer number, and obtain the updated state of the resource information, the resource information sending node may perform the following steps (31) to (33):
(31) acquiring the state of the resource information recorded in the block for storing the data after the last resource information transfer; the state of the resource information records the corresponding relation between the identifier of each node and the quantity of the resource information owned by each node;
(32) inquiring the corresponding relation between the first identifier and the resource information quantity owned by the node corresponding to the first identifier according to the first identifier, and inquiring the corresponding relation between the second identifier and the resource information quantity owned by the node corresponding to the second identifier according to the second identifier;
(33) and subtracting the resource information transfer quantity from the resource information quantity in the corresponding relation of the resource information quantity owned by the node corresponding to the first identifier, and increasing the resource information transfer quantity by using the resource information quantity in the resource information quantity owned by the node corresponding to the second identifier and the second identifier to obtain the state of the updated resource information.
And caching the state information of the resource information in the current transfer period in the resource information sending node.
In the step (4), performing increment operation on the block height, that is, performing addition operation on the block height; and updating the resource information transfer times, namely adding one to the resource information transfer times.
And the block height is used for representing the number of blocks in the sub chain used by each node in the alliance chain. Since all nodes in the federation chain should be synchronized with respect to the state of the resource data, the updated block height of each node after each transfer of resource information should be the same.
In the step (6), the process that the resource information receiving node performs the signature operation on the transfer information of the resource information by using the private key of the resource information receiving node is the prior art, and is not described herein again.
In one embodiment, the resource information receiving node signature may be 0 xBB.
Then, the obtained transfer information of the resource information having the resource information sending node signature and the resource information receiving node signature may be represented as follows:
[Ws → 20 Wd, 1, 61, 0xAA]0xBB
and 102, determining a writing node on each sub-chain of the alliance chain by broadcasting the transfer information on the alliance chain, wherein the writing node is used for updating the state of the resource information recorded on the node which is positioned on the same sub-chain as the writing node, and after the state of the resource information recorded on the node which is positioned on the same sub-chain as the writing node is updated, the state information of the resource information after the state is updated can be obtained.
In the step 102, in order to determine the writing node on each sub-chain in the federation chain, the notary node may perform the following steps (1) to (2):
(1) broadcasting the transfer information on a alliance chain, after the nodes of all sub-chains on the alliance chain acquire the transfer information, decrypting the transfer information by using a public key stored by the nodes, and feeding back decryption success information to the notary node after decryption is successful;
(2) and determining a first node which sends decryption success information in each sub-chain in the alliance chain as a writing node on each sub-chain.
In the step (1), before the notary node broadcasts the transfer information, the notary node decrypts the transfer information by using the public key stored in the notary node itself to obtain the data update duration recorded in the transfer information, and starts timing from the time when the transfer information is broadcast on the alliance chain, so as to update the state of the resource information stored in the node on each sub chain in the alliance chain within the data update duration started at the time when the transfer information is broadcast.
The public key stored by the node is used by the master node when the node becomes a node in the alliance chain through the master node authentication.
The specific process of the node decrypting the transfer information by using the public key stored in the node is the prior art, and is not described herein again.
After the decryption operation, the node may obtain the first identifier of the resource information sending node, the second identifier of the resource information receiving node, the resource information transfer amount, and the data update duration, which are recorded in the transfer information.
The specific update process of the write node, which is configured to update the status of the resource information recorded on the node located in the same child chain as the write node, and after updating the status of the resource information recorded on the node located in the same child chain as the write node, obtaining the status information of the resource information after the status update may be as follows, where the process is described in steps (31) to (36):
(31) when the data updating time does not reach the data updating duration, the writing node obtains a first quantity of resource information on the resource information sending node and a second quantity of resource information on the resource information receiving node after the resource information is transferred according to a first identification of the resource information sending node, a second identification of the resource information receiving node and the resource information transfer quantity;
(32) updating the state of the resource information recorded by the writing node by using the first quantity and the second quantity, and storing the updated state of the resource information in the block of the sub-chain where the writing node is located;
(33) acquiring state information of resource information in a current transfer period, wherein the state information of the resource information in the current transfer period comprises: the resource information transfer times of the resource information sending node completed in the current transfer period, the transfer period identifier of the current transfer period and the block height;
(34) performing increment operation on the block height to obtain the block height after the increment operation, and performing update operation on the resource information transfer times to obtain updated resource information transfer times;
(35) generating state information of the resource information by using the transfer cycle identifier of the current transfer cycle, the block height after incremental operation and the updated resource information transfer times;
(36) and broadcasting the updated state of the resource information in the sub-chain where the writing node is located, updating the state of the resource information recorded on the node located on the same sub-chain as the writing node, and updating the state of the resource information recorded on the node located on the same sub-chain as the writing node to obtain the state information of the resource information after state updating.
In the step (31), the write node performs data format processing on the first identifier of the resource information sending node, the second identifier of the resource information receiving node, and the resource information transfer number in the transfer information of the resource information by using an intelligent contract stored in the write node itself before obtaining the first number of the resource information on the resource information sending node and the second number of the resource information on the resource information receiving node after the resource information transfer according to the first identifier of the resource information sending node, the second identifier of the resource information receiving node, and the resource information transfer number, so as to obtain the first identifier of the resource information sending node, the second identifier of the resource information receiving node, and the resource information transfer number that the write node can process.
The specific process of obtaining the first quantity of resource information on the resource information sending node and the second quantity of resource information on the resource information receiving node after the resource information is transferred is similar to the process described in the step (31) to the step (33) in the process of generating the transfer information and the state information of the resource information by the resource information sending node, and is not repeated here.
The first quantity is in the process described in the step (31) to the step (33) in the process of the resource information sending node generating the transfer information and the state information of the resource information: and subtracting the quantity value of the resource information transfer quantity from the quantity of the resource information in the corresponding relation of the quantity of the resource information owned by the node corresponding to the first identifier.
The second quantity is in the process described in the step (31) to the step (33) in the process of the resource information sending node generating the transfer information and the state information of the resource information: and increasing the quantity value of the resource information transfer quantity by utilizing the quantity of the resource information in the quantity of the resource information owned by the node corresponding to the second identifier and the second identifier.
In the step (35), after obtaining the state information of the resource information after the state update, the write node caches the obtained state information of the resource information after the state update.
In the step (36), after the status of the resource information recorded on the node located in the same child chain as the writing node is updated, the process of obtaining the status information of the resource information after the status update is similar to the process described in the step (33) to the step (35) of the writing node, and is not described again here.
When the data update time reaches the data update duration, the notary node stops the data update of each sub-chain in the alliance chain, and compares the state information of the resource information among the nodes in the alliance chain through the following step 104.
And 104, comparing the state information of the resource information among the nodes in the alliance chain to obtain a comparison result.
Here, comparing the state information of the resource information between the nodes in the federation chain refers to comparing whether the transfer cycle identifier of the current transfer cycle, the block height after the incremental operation, and the transfer frequency of the updated resource information in the state information cached by each node are consistent. And when the transfer cycle identifier of the current transfer cycle, the block height after the incremental operation and the updated resource information transfer times in the state information cached by each node are all consistent, obtaining a comparison result of consistency of the state information obtained by all nodes in the alliance chain. And proceeds to the following step 106.
And when the transfer cycle identifier of the current transfer cycle, the block height after the incremental operation or the updated resource information transfer times in the state information cached by each node are inconsistent, obtaining a comparison result of the inconsistency of the state information obtained by all the nodes in the alliance chain. And proceeds to the following step 108.
As can be seen from the above contents of step 104 to step 106, by comparing the state information of the resource information between the nodes in the federation chain, the data consistency on the federation chain is verified, so that the data consistency on the federation chain is ensured not to be tampered, and the data inconsistency between updated nodes due to delay or malicious nodes (intentionally writing wrong information) is prevented.
And 106, when the comparison result indicates that the state information obtained by all the nodes in the alliance chain is consistent, sending a resource information transfer instruction to the resource information sending node, so that the resource information sending node sends resource information of the resource information transfer quantity to the resource information receiving node, and completing the resource information transfer operation.
After the resource information transfer operation is completed, the notary node can send the resource information of the resource information reward quantity to the writing nodes of all the sub chains on the alliance chain according to the preset resource information reward quantity, so that the writing nodes are rewarded, and then the reward result is broadcasted in the alliance chain.
And 108, when the comparison result indicates that the state information obtained by all the nodes in the alliance chain is inconsistent, broadcasting a transaction failure instruction in the alliance chain, so that each node in the alliance chain withdraws the state of the asset information to be the state before the resource information is transferred.
In step 108, the node recalls the state of the asset information to be in the state before the resource information is transferred, which means that the node performs the state update and recall operation on the asset information and releases the block storing the state of the asset information after the update, so that the state of the asset information recorded in each node in the federation chain can be recalled to be in the state before the resource information is transferred.
Further, the notary node may generate a resource information punishment instruction according to a preset resource information punishment quantity, and send the resource information punishment instruction to the writing node which does not complete data synchronization in the alliance chain, so that the writing node which does not complete data synchronization in the alliance chain feeds back the resource information of the resource information punishment quantity to the notary node, and punishment is performed on the writing node which does not complete data synchronization.
It can be seen from the above contents of steps 106 to 108 that the write-in node that completes data synchronization on time can obtain resource information of resource information reward amount each time, and the write-in node that completes data synchronization over time does not complete data synchronization, and the resource information of resource information punishment amount is deducted, so that the node in the federation chain is prevented from doing malicious activities by the resource information punishment system, and meanwhile, the node is encouraged to become the write-in node, and the purpose of timely synchronizing data in the federation chain is achieved.
The above contents show that the notary node synchronizes data by adopting the transfer information of the resource information, and verifies whether the transaction is completely synchronized by utilizing the state information of the resource information, so as to achieve final consistency. When resource information transfer occurs on one chain, the resource information sending node generates transfer information and state information of the resource information, and the notary node reads and writes the transfer information and the state information of the resource information and broadcasts the transfer information of the resource information. And an intelligent contract is configured on the heterogeneous chain, so that nodes on the heterogeneous chain can read the transfer information of the resource information, and then the notary node determines a write-in node on the heterogeneous chain to complete data updating on each chain. After the data updating is completed, the notary node confirms whether to perform resource information transfer operation or not by comparing state information of the resource information generated by each node in the alliance chain, and the notary rewards the writing-in node of the heterogeneous chain after the resource information transfer is completed.
To sum up, in the federation link data processing method provided in this embodiment, the notary node sends the transfer information of the resource information sent by the resource information receiving node to the write-in node of the child chain where the node where the resource information is transferred is located, updating the state of resource information recorded on a node located on the same sub-chain as the writing node through the writing node, compared with the method that when the notary node synchronizes the data between the heterogeneous chains in the related art, the data needs to be synchronously written into all the nodes in the other chain in the heterogeneous chains at the same time, the state of the resource information recorded on the node which is positioned on the same sub-chain as the write-in node is updated through the write-in node, and the notary node is not required to write data into all nodes in the sub-chain synchronously, so that the processing time of the notary node is reduced, and the data reading and writing efficiency is improved; moreover, the consistency of the data on the alliance chain is verified by comparing the state information of the resource information among the nodes in the alliance chain, and the transfer operation of the resource information is completed when the state information obtained by all the nodes in the alliance chain is consistent, so that the consistency of the data on the alliance chain is ensured and the data on the alliance chain is not tampered.
