In order to explain the technical means described in the present application, the following description will be given by way of specific examples.
Referring to fig. 1, fig. 1 is a first flowchart of a method for managing and controlling a block chain state according to an embodiment of the present application. As shown in fig. 1, a method for managing a blockchain state includes the following steps:
The current chain state may be any one of an initial state, a chain available, a chain unavailable, a chain deleted.
In the initial state, corresponding to the situation that no chain is established in the block chain platform, a new operation on the chain can be executed at this time. And in the chain available state, the chain can be restarted, stopped, deleted and the like. In the state that the chain is unavailable, operations such as deleting and enabling the chain can be carried out.
The management and control method is realized by setting a chain drive, the chain drive is a middleware for judging the state of the chain according to the state of the node, has the functions of collecting the state of the node, judging the state of the chain and setting the state of the chain, plays an important role in maintaining the relationship between the chain and the node, and can realize scientific synchronization of the states of the chain and the node.
Specifically, in the subsequent process, the control of the states of the nodes and the chain can be realized by setting a state machine, the chain driver acquires the changed node states related to the processing actions triggered by the user on the basis of the state machine, and the states of the chain to which the nodes belong are set on the basis of the changed node states.
The state machine is a directed graph and consists of a group of nodes and corresponding transfer functions. Nodes of the state machine represent the state of the target object and by running a transfer function in response to an event, proceed from one node to the next. Referring to fig. 2, a block chain lifecycle management state machine flow diagram is shown.
The state machine of the block lifecycle management has states including: "initial state/existing chain", "chain available", "in chain processing", "chain unavailable", "chain deleted", "node available", "in node processing", "node unavailable", "node deleted". Wherein "initial state/existing chain" is the initial state and "chain deleted" is the terminal state.
Events that have (i.e., the user triggers the processing action performed by the system) include: the method comprises the steps of creating a chain, adding a node, deactivating the chain, restarting the chain, starting the chain, deleting the chain, deactivating the node, restarting the node, starting the node and deleting the node. These events correspond to different state transition logic.
The conditions for each state transition are the user input parameters, system environment variables, and the operating software and hardware environment during the actual operation of the system, and will generally be reflected in the outcome of whether the action was successfully performed while in "chain processing" or "node processing", which is either "chain available" or "chain unavailable" for the chain and "node available" or "node unavailable" for the node. And the chain drive acquires the result states of whether the actions are successful or not, and determines the chain state according to the node states after the actions are executed.
Here, the user may be given the trigger for different processing actions in different chain states. For example, in the initial state, corresponding to the situation that no chain is established in the blockchain platform, a new operation on the chain can be performed at this time. In the chain available state, operations such as restarting, deactivating and deleting can be carried out on the chain. In the state that the chain is not available, operations such as deleting and enabling the chain can be carried out.
Since a chain has an inclusion-contained relationship with a node, a change in the state of the node is caused after a processing action is executed, regardless of whether the processing action is a user-triggered processing action on the chain or a processing action on the node.
And acquiring the state of the subsequent chain by acquiring the final state of the nodes in the subsequent chain after the processing action is executed.
Specifically, in the process of collecting node states by the chain driver, when a certain node enters the states of "node available", "node unavailable", and "node deleted", the state is fed back to the chain driver. The chain driver records the state into the final state of the node in the action.
As an optional implementation manner, if the user side triggers a processing action of a chain or a node in the chain in the block chain platform based on the current chain state, after the processing action is completed, acquiring a final state of the node fed back by the node in the processing action, including:
and if the current link state is the initial state, the user side triggers the creation action of the link based on the initial state, and after the creation action of the link is processed, the final state of the node after the creation action of each node related in the created link is executed is obtained.
The node end state includes any one of node available, node unavailable, and node deleted.
If a chain has not been created in the system, then the chain state is considered to be the initial state, and the action of creating a chain may be performed. After the action of creating the chain is executed, the chain in the state machine enters a 'chain processing' state, and all nodes in the chain enter a 'node processing' state. If a certain node in the chain is successfully established, the node enters a node available state and feeds back the state to the chain driver; if the creation fails, a 'node unavailable' state is entered and the state is fed back to the chain driver.
Differently, as another optional implementation manner, if the user side triggers a processing action of a chain or a node in the chain in the block chain platform based on the current chain state, after the processing action is completed, acquiring a final state of a node fed back by the node in the processing action, including:
And if the current link state is the link available state or the link unavailable state, the user side triggers the node adding action in the link based on the current link state, and after the node adding action is processed, the node adding action is obtained, and the final state of the node which is added in the link and the node which is originally in the link is obtained.
Wherein the node final state comprises any one of node available, node unavailable and node deleted.
If the current chain state is a chain available state or a chain unavailable state, which indicates that a created chain exists in the system, namely, the chain is in an 'existing chain' state, the action of adding a node in the chain can be executed. After the action of the new node is executed, the new node in the state machine enters a node processing state, and the state of the existing node in the chain is unchanged. If the node is successfully added after the node addition action is processed, the node enters a node available state and feeds back a node state corresponding to the processing result to the chain drive; and if the new addition fails, the node enters a 'node unavailable' state, and feeds back a node state corresponding to the processing result to the chain drive. Here, in order to subsequently determine the link state, it is necessary to obtain the final state of the node of the existing node in the link at the same time.
Differently, as another optional implementation manner, if the user side triggers a processing action of a chain or a node in the chain in the block chain platform based on the current chain state, after the processing action is completed, acquiring a final state of a node fed back by the node in the processing action, including:
if the current chain state is the chain available state, the user side triggers the restarting or stopping action of the chain based on the chain available state, the node state in the chain is determined to be a first target node available for the node, and after the restarting or stopping action of the chain is processed, the final state of the node after the first target node executes the restarting or stopping action is determined.
Wherein the node final state comprises any one of node available, node unavailable and node deleted.
When restarting or deactivating a chain, a target node in the chain, the state of which is available to the node, needs to be restarted or deactivated correspondingly.
If the chain is in a "chain available" state in the system, an action to deactivate the chain or restart the chain may be performed. And executing the actions of stopping the chain or restarting the chain, wherein the chain in the state machine enters a 'chain processing' state, and meanwhile, the state machine sets all nodes to enter a 'node processing' state. And correspondingly executing actions of stopping the nodes or restarting the nodes by the target nodes of the nodes in the usable node state in the chain. Performing a deactivate node or restart node action, the node will enter a "node in progress" state. If the deactivation of a certain node is successful, the node enters a 'node unavailable' state and feeds back the state to a chain driver; if the deactivation fails, a "node available" state is entered and the state is fed back to the chain drive. If a certain node is restarted successfully, the node enters a node available state and feeds back the state to a chain drive; and if the restart fails, entering a 'node unavailable' state and feeding back the state to the chain driver.
Differently, as another optional implementation manner, if the user side triggers a processing action of a link or a node in the link in the block chain platform based on the current link state, after the processing action is completed, acquiring a final state of the node fed back by the node in the processing action, including:
and if the current link state is the link unavailable state, the user side triggers the starting action of the link based on the link unavailable state, then the node state in the link is determined to be a second target node with the node unavailable, and after the starting action of the link is processed, the final state of the node after the starting action is executed by the second target node is determined.
Wherein the node final state comprises any one of node available, node unavailable and node deleted.
If a chain is in a "chain unavailable" state in the system, an action to enable the chain may be performed. The enable chain action is performed and the state machine sets the chain to the "in chain processing" state and sets all nodes to enter the "in node processing" state. And correspondingly executing the action of enabling the node by the target node of the node in the 'node unavailable' state in the chain. An enable node action is performed and the node will enter a "node in progress" state. If a certain node is successfully started, the node enters a 'node available' state and feeds back the state to a chain drive; and if the node fails to be enabled, entering a 'node unavailable' state and feeding back the state to the chain driver.
Differently, as a further optional implementation manner, if the user side triggers a processing action of a link or a node in the link in the block chain platform based on the current link state, after the processing action is completed, acquiring a final state of the node fed back by the node in the processing action, including:
and if the current link state is the link available state or the link unavailable state, the user side triggers the deletion action of the link based on the current link state, and after the deletion action of the link is processed, the final state of the nodes of all the nodes related in the link is set to be the deleted state of the nodes.
If the current chain state is a chain available state or a chain unavailable state, which indicates that a created chain exists in the system, namely, the chain is in an 'existing chain' state, an action of deleting the chain can be executed. And executing the action of deleting the chain, and simultaneously executing the action of deleting the nodes in the chain, wherein the nodes enter a 'node deleted' state and feed back the state to the chain drive.
And 103, determining the final chain state in the block chain platform based on the consensus algorithm in the block chain platform according to the final state of the node.
And the chain drive collects the state fed back by the node and combines the states of other existing nodes, judges whether the chain state is available according to the consensus algorithm of the block chain, sets the chain state as 'chain available' if the chain state is available, and sets the chain state as 'chain unavailable' if the chain state is unavailable.
Specifically, for a certain action, after the chain driver records enough final states of the nodes (the final states of the nodes are "node available", "node unavailable", and "node deleted"), the final state of the chain is determined according to the type of the consensus algorithm of the current chain.
If more information about the node (which refers to information other than the node state, such as the type of the node) needs to be utilized in the determination process, the node also needs to feed back the information when feeding back the state. Whether more information is fed back depends on the consensus algorithm of the current chain, so that the chain-driven judgment process can be different for different chains and different consensus algorithms.
And step 104, setting the current chain state of the block chain platform as the final chain state.
Wherein the final chain state includes any one of chain available, chain unavailable, and chain deleted.
When the chain state is set, the chain drive determines the final state of the chain for a certain processing operation, and then sets the state of the chain to the final state (the final state of the chain is "chain available", "chain unavailable", or "chain deleted").
In the process, the state machine is used, so that the process of block chain life cycle management is coherent and clear, and the maintenance is easy. If the 'chain unavailable' or 'node unavailable' state is entered due to failure when a certain action is executed, the action can be executed again at regular time, the original state flow is repeated, and other functions such as automatic recovery and the like are easily realized. And the state machine is combined with two technical means of a mechanism for setting node states by a chain and chain driving, and the relationship between two objects of the chain and the nodes is scientifically maintained. When the user operates the nodes, all the nodes can immediately respond, and when the user operates the nodes, the change of the chain can be correctly and timely sensed.
In the embodiment of the application, the current chain state in the block chain platform is output to the user terminal, if the user terminal triggers the processing action of the chain or the nodes in the chain in the block chain platform based on the current chain state, after the processing action is finished, the final state of the nodes fed back by the nodes in the processing action is obtained, the final chain state in the block chain platform is determined according to the final state of the nodes and based on the consensus algorithm in the block chain platform, the current chain state of the block chain platform is set as the final chain state, the process introduces a chain drive as a middleware for judging the chain state according to the state of the nodes in the block chain, the functions of collecting, judging and setting the chain state of the nodes are realized in each processing action of the block chain, the function of maintaining the relationship between the chain and the nodes is realized, the scientific synchronization of the chain and the node state is realized, and the user can timely sense the cooperative change of the states between the nodes and the chain, and the state control effect of the block chain platform is improved.
Different embodiments of the block chain state management and control method are also provided in the embodiment of the application.
Referring to fig. 3, fig. 3 is a second flowchart of a block chain state management and control method provided in the embodiment of the present application. As shown in fig. 3, a method for managing and controlling a block chain state includes the following steps:
The implementation process of this step is the same as that of step 101 in the foregoing embodiment, and is not described here again.
The implementation process of this step is the same as that of step 102 in the foregoing embodiment, and is not described here again.
And step 303, judging whether the number of nodes corresponding to the final states of different nodes in the chain is greater than a threshold value or not based on a consensus algorithm in the block chain platform according to the final states of the nodes.
Different nodes in a chain may have different node states, such as some processing nodes in an available state and some nodes in an unavailable state. And counting the number of nodes in different node states so as to judge the state of a chain containing the nodes.
In step 304, if the number of nodes in the chain whose final state is the node available state is greater than the first threshold, it is determined that the final chain state in the block chain platform is the chain available state.
And counting the number of nodes in the node available state, and determining that the chain state is available when the number of the nodes is greater than a threshold value.
In step 305, if the number of nodes in the chain whose final state is the node unavailable state is greater than the second threshold, it is determined that the final chain state in the blockchain platform is the chain unavailable state.
And counting the number of nodes in the node unavailable state, and determining that the chain state is chain unavailable when the number of the nodes is greater than a threshold value.
In step 306, if the final state of the nodes in the chain is that the number of the nodes deleted by the nodes is greater than the third threshold, it is determined that the final state of the chain in the block chain platform is that the chain is deleted.
The third threshold is, for example, the value of the total number of nodes in the chain minus 1.
The implementation process of this step is the same as that of step 104 in the foregoing embodiment, and is not described here again.
The following describes an example of the above process, taking the processing action of creating a chain when the system is in the initial state as an example.
The user triggers the system to perform the action of creating the chain. The chain to be created is Hyperchain, and 4 VP-type nodes are created by adopting an RBFT (Redundant Byzantine Fault Tolerance) consensus algorithm to form a 1 chain; the state machine sets the chain to be in the 'chain processing' state, and sets 4 VP nodes to be in the 'node processing' state; the system installs 4 VP nodes of Hyperchain on a specified host according to the needs of a user. For a certain node, if the installation process is smoothly executed and the node is successfully established, the system sets the node to be in a 'node available' state and sends the node state to the chain drive through an HTTP request; if the installation process is wrong and the node is failed to be created, the system sets the node to be in a 'node unavailable' state and sends the node state to the chain driver through an HTTP request. Suppose that 3 nodes are successfully created during the installation, the node is in the state of being available, and 1 node is failed to be created, and the node is in the state of being unavailable.
After the chain driver receives the feedback states of all 4 nodes in sequence (namely 3 nodes are available and 1 node is unavailable), the chain state is judged according to the consensus algorithm of the block chain. The RBFT consensus algorithm of the block chain Hyperchain requires that: when the number of the available VP nodes is larger than or equal to 3/4 of the total number of the nodes, the chain is available; otherwise the chain is not available. In this case, the total node number is 4, and the available VP node number is 3, which satisfies the requirement, so the chain driver determines that the current chain is available. The chain drive sets the chain state to "chain available". The execution of the action of creating the chain ends.
In the embodiment of the application, the current chain state in the block chain platform is output to the user terminal, if the user terminal triggers the processing action of the chain or the nodes in the chain in the block chain platform based on the current chain state, after the processing action is finished, the final state of the nodes fed back by the nodes in the processing action is obtained, the relationship between the number of the nodes corresponding to the final states of different nodes in the chain and the threshold is judged based on the consensus algorithm in the block chain platform according to the final state of the nodes to determine the final chain state in the block chain platform, the current chain state of the block chain platform is set as the final chain state, the process introduces a chain drive as a middleware for judging the chain state according to the states of the nodes in the block chain, the functions of collecting the node states, judging the chain states and setting the chain states are realized in each processing action of the block chain, and the function of maintaining the relationship between the chain and the nodes is played, the state control method and the state control system realize scientific synchronization of the chain and the node state, enable a user to timely sense the cooperative change of the state between the node and the chain, and improve the state control effect of the block chain platform.
