Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 is a schematic configuration diagram of an implementation environment according to an embodiment of the present application. As shown in FIG. 1, the implementation environment may include: a pre-established blockchain 10, and at least two management nodes 20, e.g., 3 management nodes 20 are shown in fig. 1, which establish a communication connection with the blockchain 10. Each management node 20 may establish a communication connection with the blockchain 10 in a wired or wireless manner. Each management node 20 may manage the blockchain 10 through the communication connection, for example, issue an intelligent contract, that is, each management node 20 has a management right for the blockchain 10.
Wherein the blockchain 10 may include a plurality of nodes, for example, only 6 nodes (node 101 to node 106) are shown in fig. 1. The plurality of nodes can establish communication connection through a wired network or a wireless network, and synchronize data through the communication connection. When any node receives data, the data may be broadcast to all nodes in the entire blockchain 10 (i.e., broadcast to the blockchain 10) so that other nodes in the blockchain 10 may receive and store the data. Any two management nodes 20 of the at least two management nodes 20 may also establish a communication connection in a wired or wireless manner, and may synchronize management operation data for the blockchain 10 based on the communication connection. The management operation data is data obtained by performing management operation on the block chain.
In the embodiment, each management node 20 of the at least two management nodes 20 and each node of the block chain 10 may be an electronic device. Optionally, the electronic device may be a smart phone, a tablet computer, a notebook computer, a desktop computer, a Moving Picture expert Audio Layer Iv (MP 4) player or a server, and the like.
It should be noted that, among the plurality of nodes included in the blockchain 10, there are at least two nodes deployed by different organizations, for example, referring to fig. 1, the 6 nodes may be nodes deployed by three different organizations. Each organization has an Internet Data Center (IDC) that may include a plurality of nodes, at least one of which is deployed in the blockchain 10 and at least one of which is a management node 20 of the blockchain 10. Accordingly, the 3 management nodes shown in fig. 1 are nodes in IDCs of 3 different organizations.
For example, referring to fig. 1, node 101 and node 102 in blockchain 10 may be the first enterprise deployed node, i.e., also the node in IDC 1; node 103 and node 104 in blockchain 10 may be nodes deployed by a second organization, i.e., also nodes in IDC 2; nodes 105 and 106 in blockchain 10 may be nodes deployed by a third organization, i.e., also nodes in IDC 3.
The embodiment of the application provides a method for managing block chain resources, which can be applied to a block chain resource management device. Referring to fig. 2, the method may include:
step 301, acquiring resource locking information of a target management node of a block chain.
The resource locking information is used for indicating a target resource in a locking block chain. The target resource refers to any one of a plurality of shared resources in the block chain, and the target management node may perform a target management operation on the block chain based on the target resource. The block chain is provided with at least two management nodes, and the target management node is any one of the at least two management nodes.
Optionally, the resource locking information may carry an identifier of the target resource.
Step 302, determine whether the target resource is locked.
In the embodiment of the present application, the corresponding relationship between the identifier of the shared resource and the locking flag of the shared resource is recorded in the blockchain resource management device. When acquiring the resource locking information of the target management node, the blockchain resource management device may determine whether the target resource is already locked according to the identifier of the target resource carried in the resource locking information, and the corresponding relationship between the identifier of the shared resource and the locking flag of the shared resource.
Step 303, when the target resource is not locked, sending resource locking information to other management nodes except the target management node of the block chain.
Alternatively, the blockchain resource management device may send the resource locking information to other management nodes of the blockchain except for the target management node based on a consensus algorithm.
To sum up, the embodiment of the present application provides a method for managing resource of a block chain, where the method may obtain resource locking information of a target management node of the block chain, where the resource locking information is used to indicate that a target resource in the block chain is locked, and send the resource locking information to other management nodes of the block chain except the target management node when the target resource is not locked. When determining that the target resource is not locked, the blockchain resource management device can send resource locking information to other management nodes except the target management node of the blockchain, so that the target resource can be ensured not to be occupied by other management nodes when being occupied by the target management node, and the phenomenon of management operation failure caused by incapability of guaranteeing atomicity of management operation when a plurality of management nodes simultaneously manage and operate the blockchain based on the target resource is avoided.
In the embodiment of the present application, referring to fig. 3, each management node 20 of the blockchain may include a management component 201 and an auxiliary component 202 (also referred to as a multi-party administration plug-in), and the method for managing blockchain resources provided by the embodiment of the present application may be applied to the auxiliary component of the target management node. The following description will be made by taking the application of the blockchain resource management method to an auxiliary component of a target management node as an example. Referring to fig. 3, the method may include:
step 401, obtaining resource locking information sent by a management component in a target management node.
The resource locking information is used for indicating a target resource in a locking block chain. The target resource refers to any one of a plurality of shared resources in the block chain, and the target management node may perform a target management operation on the block chain based on the target resource. The block chain is provided with at least two management nodes, and the target management node is any management node of the block chain.
Optionally, the resource locking information may carry an identifier of the target resource.
Step 402, determine if the target resource has been locked.
In the embodiment of the present application, the auxiliary component of each management node records a correspondence between an identifier of a shared resource and a lock flag of the shared resource. When the auxiliary component of the target management node acquires the resource locking information, whether the target resource is locked or not can be determined according to the identifier of the target resource carried in the resource locking information, the recorded identifier of the shared resource and the corresponding relation of the locking mark of the shared resource.
If the target resource has been locked, step 403 may be performed. If the target resource is not locked, step 404 may be performed.
And step 403, sending locking prompt information to a management component in the target management node.
The locking prompt message is used for indicating that the target resource is locked and cannot be acquired.
Step 404, sending the resource locking information to auxiliary components in other management nodes except the target management node of the blockchain.
In this embodiment, the auxiliary component of the target management node may synchronize the resource locking information to auxiliary components in other management nodes of the blockchain except the target management node based on a consensus algorithm, so as to ensure consistency of the resource locking information received by each of the other management nodes.
Optionally, the consensus algorithm may include: a Practical Byzantine Fault Tolerant (PBFT) algorithm, or a RAFT algorithm.
When the auxiliary component of the target management node determines that the target resource is not locked, the auxiliary component of the target management node can send the resource locking information to the auxiliary components in other management nodes except the target management node, so that the auxiliary components in the other management nodes update the recorded corresponding relation between the identifier of the shared resource and the locking mark of the shared resource according to the resource locking information, thereby ensuring that the other management nodes do not repeatedly occupy the target resource, realizing the locking of the target resource, further ensuring the atomicity of the management operation of the target management node on the block chain based on the target resource, and ensuring that the management operation of the target management node on the block chain is not interrupted.
Fig. 5 is a schematic structural diagram of an auxiliary assembly provided in an embodiment of the present application. Referring to fig. 5, the auxiliary component 202 of each management node may include a consensus module 2021, and the auxiliary component 202 of the target management node may synchronize the resource lock information to the consensus module 2021 of other management nodes through the consensus module 2021, so that the other management nodes may obtain the resource lock information. Optionally, the consensus module may be developed based on a RAFT algorithm, for example, the consensus module may be an ETCD. Among them, the ETCD is a highly available key-value storage system, and is mainly used for shared configuration and service discovery.
It should be noted that the auxiliary component in each management node of the block chain may form the sub-block chain, that is, the auxiliary component in each management node is a node in the sub-block chain. The target management node may broadcast the resource lock information in the sub-block chain when determining that the target resource is not locked, so that each node (i.e., the auxiliary component) in the sub-block chain may acquire the resource lock information.
Because the block chain has the property of tamper resistance, and each auxiliary component is a node in the sub-block chain, the credibility of the synchronous resource locking information can be effectively ensured, and the atomicity of the target management operation of the target management node on the block chain based on the target resource is further ensured after the target management node occupies the target resource.
The auxiliary component can determine the locking state of the target resource by performing the above steps 401 to 404, and lock the target resource when the target resource is not locked.
In this embodiment of the application, a management component of a target management node may obtain management operation data (that is, data to be stored described below) for a block chain, and after obtaining the management operation data, the target management node may synchronize the management operation data to other management nodes, so that the other management nodes perform subsequent management operations.
Because the management components of the management nodes of the block chain are mutually independent, the auxiliary components of the management nodes are communicated, and the management component and the auxiliary component of each management node are in communication connection, the management component of the target management node can communicate with the management components of other management nodes through the auxiliary components, so that data synchronization is performed. In order to ensure consistency of Data written into the databases of the management nodes of the block chain, the management component may write the acquired management operation Data into its database (Data Base, DB) through the auxiliary component. In the process of writing the management operation data into the database through the auxiliary component, if the management operation data can be written into the database, the management operation data can be synchronized to the auxiliary components of other management nodes. If the management operation data cannot be written into the database, the management operation data cannot be synchronized to the auxiliary components of other management nodes.
Step 405, acquiring data to be stored sent by the management component.
When the target management node acquires the data to be stored, the data to be stored can be sent to the auxiliary component, and correspondingly, the auxiliary component can acquire the data to be stored sent by the management component.
The data to be stored may be management operation data of the block chain by the management component described above. For example, the data to be stored may be an intelligent contract installed on a certain node of the blockchain for the management component. An intelligent contract is a contract program that executes automatically according to certain conditions.
And step 406, storing the data to be stored in the database of the target management node.
The auxiliary component may write the data to be stored into the database of the target management node, that is, store the data to be stored into the database of the target management node.
In this embodiment, referring to fig. 5, each auxiliary component of the management node may include an interface module 2022, where the interface module 2022 may provide a service for writing data to be stored in the database to the management component. That is, the interface module 2022 may be a channel (also referred to as an interface) for writing data between the management component and the database of the management node. Optionally, the interface module may be a Hypertext Transfer Protocol (HTTP) interface module.
For example, referring to fig. 6, after the management component of the target management node acquires the data to be stored, step a may be performed, that is, the data to be stored is sent to the interface module 2022 of the auxiliary component 202. Accordingly, the interface module 2022 may obtain the data to be stored, and may perform step b, that is, directly write the data to be stored into the database DB of the target management node, even if the data to be stored falls to the database DB of the target management node 20.
It should be noted that the database is provided with a task monitor, and the task monitor can monitor whether new data is written in the database in real time (i.e. whether new data exists in the database). And if the task monitor detects that new data is written in the database, the task monitor can send prompt information to prompt the auxiliary component to synchronize the newly added data to other management nodes. In this way, consistency between the data written in the database of the target management node and the data written in the database of the other management node can be ensured. The newly added data refers to data to be stored written into the database of the management node.
Step 407, sending the data to be stored to the auxiliary components of other management nodes except the target management node of the block chain.
After writing the data to be stored into the database, the auxiliary component of the target management node may acquire the data to be stored from the database, and may send the data to be stored to the auxiliary components of other management nodes except the target management node.
In this embodiment, referring to fig. 5, the auxiliary component of each management node may further include: a write (writer) module 2023, which writer module 2023 can monitor in real time whether a task monitor that manages the database of the node issues a prompt message. If the prompt message is sent, the writer module 2023 may determine that new data (at this time, the new data may also be referred to as data to be synchronized) exists in the database of the target management node, that is, the new data may be read from the database and written into the consensus module 2021 of the auxiliary component. That is, the writer module 2023 may read the data to be stored written to the database and asynchronously write it to the consensus module 2021. The consensus module 2021 may then synchronize the new data into the auxiliary components of other management nodes based on a consensus algorithm. Accordingly, other management nodes can obtain the newly added data.
For example, when the writer module 2023 detects that there is prompt information in the database, as shown in fig. 6, step c may be performed, that is, new data in the database DB is read, and then step d may be performed, that is, the read new data is written into the consensus module 2021. The consensus module 2021 may then perform step e, synchronizing the newly added data to the auxiliary component 202 of the other management node.
The auxiliary component can implement data synchronization between the target management node and other management nodes by performing the above steps 405 to 407. Moreover, according to the above data synchronization process, after writing the data to be stored in the database of the management node, the auxiliary component can write the data to be stored written in the database into the consensus module, thereby effectively ensuring atomicity of two-step write operations (i.e., writing the data to be stored in the database of the management node and writing the data to be stored in the database into the consensus module), ensuring that the data to be stored written in the database of the management node can be written in the consensus module, and then synchronizing to the databases of other management nodes through the consensus module, thereby ensuring consistency between the data written in the database of the target management node and the data written in the databases of other management nodes.
And step 408, acquiring the resource unlocking information sent by the management component.
The resource unlocking information is used for indicating the unlocking target resource.
In the embodiment of the present application, if the management component determines that the management operation based on the target resource is completed, the resource unlocking information may be sent to the auxiliary component, and accordingly, the auxiliary component may obtain the resource unlocking information.
Step 409, sending the resource unlocking information to the auxiliary components of other management nodes except the target management node of the block chain.
The auxiliary component may synchronize the resource unlocking information to auxiliary components in other management nodes of the block chain except the target management node based on a consensus algorithm, so as to ensure consistency of the resource unlocking information received by each of the other management nodes.
After the auxiliary component of the target management node determines that the management operation based on the target resource is completed, the auxiliary component can send the resource unlocking information to the auxiliary component, so that the auxiliary component in other management nodes can update the recorded corresponding relation between the identifier of the shared resource and the locking mark of the shared resource according to the resource unlocking information, and therefore it is ensured that other management nodes can obtain the target resource later, namely, the target resource is unlocked.
For example, the auxiliary component may synchronize the resource unlocking information to the common identification modules of the other management nodes through the common identification modules thereof, so that the other management nodes can obtain the resource unlocking information.
It should be noted that, in the embodiment of the present application, a timer may be set in each auxiliary component of the management node, and each auxiliary component stores a resource unlocking period. When the auxiliary component of the target management node sends the resource locking information to the auxiliary components in other management nodes except the target management node of the block chain, the timer is started and starts timing, if the auxiliary component does not receive the resource unlocking information sent by the management component in the resource unlocking period, the auxiliary component can generate resource unlocking information according to the identifier of the target resource and send the resource unlocking information to the auxiliary components of other management nodes, namely, the target resource is forcibly unlocked.
Fig. 7 is a flowchart of another method for managing blockchain resources according to an embodiment of the present application, where the method may be applied to a blockchain resource management apparatus, and the apparatus may be disposed in an auxiliary component of a target management node, or the apparatus may be an auxiliary component of the target management node. Referring to fig. 7, the method may include:
and step 410, receiving data to be stored sent by auxiliary components of other management nodes except the target management node of the block chain.
