Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
Referring to fig. 1, fig. 1 is a flowchart of a method for confirming a block chain operation according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
In the embodiment of the present invention, the blockchain operation may be an operation that can be performed using a blockchain, such as a transaction, a lottery, an auction, and the like. The target block in which the above-mentioned blockchain operation is located may be a block in which the blockchain operation is performed, or may be referred to as a block in which data of the blockchain operation is recorded.
The obtaining of the risk state of the blockchain operation may be obtaining the risk state by obtaining parameters of all or part of blockchain operations on the blockchain, or may be obtaining the risk state by monitoring all or part of nodes of the blockchain. In addition, the risk status may indicate whether a risk exists for the blockchain operation or may indicate a risk level of the blockchain operation.
And 102, if the risk state meets a preset state condition, confirming the block chain operation.
The preset state condition may be set before step 102 is executed, and the preset state condition may be that no risk exists or that the risk level is lower than the preset risk level.
The operation of confirming the blockchain operation may be to confirm the result of the blockchain operation, for example: and determining that the operation is successful. In addition, after step 102, a confirmation result of the confirmation operation may also be output, for example: and returning an operation confirmation result to the user or the server.
The operation of confirming the blockchain operation may be to confirm the blockchain operation before the blockchain generates a next block of the target block. Or, when the risk state is judged to meet the preset state condition, the block chain operation is confirmed.
It should be noted that, in the embodiment of the present invention, if the risk state does not satisfy the preset state condition, the method may perform a confirmation operation on the blockchain operation when at least one block is generated after the target block is generated by the blockchain. For example: in the case of regenerating 5 or 6 blocks, a confirm operation is performed on the block chain operation.
It should be noted that the block chain operation confirmation method provided in the embodiment of the present invention may be applied to an electronic device capable of operating based on a block chain, for example: the electronic device may be a node of the block chain, such as a server, a computer, a mobile phone, a tablet computer, and the like.
In the embodiment of the invention, under the condition that a target block where a block chain operation is generated is located, the risk state of the block chain operation is obtained; and if the risk state meets a preset state condition, confirming the block chain operation. Therefore, under the condition that the risk state meets the preset state condition, the block chain operation is confirmed, and therefore working efficiency can be improved.
Referring to fig. 2, fig. 2 is a flowchart of another block chain operation confirmation method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:
In an embodiment, the acquiring the risk state of the blockchain operation may be a risk state sent by a risk control node that receives a blockchain, that is, in the embodiment of the present invention, a risk control node may be added to a blockchain network, and the node may monitor all operations in the entire blockchain network and each node in the blockchain network in real time. Therefore, the block chain network can be safer and more reliable through the risk control node.
For example: taking a blockchain as a hundred-degree hyperlink, the blockchain operation is exemplified as a transaction, as shown in fig. 3, a plurality of nodes of the blockchain are exemplified by a node 1 and a node n in the figure, and each node stores a plurality of blocks and an intelligent contract. The risk control node monitors all operations and nodes in the blockchain network, for example: when the risk control node finds the behavior with high risk, the risk level of the system or the user is raised, the monitored risk state is fed back to the transaction system, and the transaction system executes corresponding confirmation operation according to the fed-back network state.
It should be noted that, in the embodiment of the present invention, the rule (e.g., the transaction rule) of the area chain operation may be written into the intelligent contract, so that the intelligent contract is public, and thus the public and fair operation can be ensured. In addition, data of block chain operation (for example, transaction data generated by a transaction system based on a hundred degree super chain) may be stored in the block chain, and in the embodiment of the present invention, a consensus mechanism of the block chain may be a released Proof of ownership (DPOS), and further, a Time-based released Proof of ownership (TDPOS) mechanism may be used, so that each node flows out blocks according to the consensus mechanism, and forking is avoided as much as possible, thereby improving the operation performance of the block chain.
In another embodiment, the operation and/or the node in the blockchain network are monitored to obtain the risk state of the blockchain operation, that is, in this embodiment, a monitoring function may be added to an existing node in the blockchain network instead of adding a special risk monitoring node to reduce the complexity of the network.
In this embodiment, multiple risk levels may be preconfigured, for example: high risk level and low risk level, etc. The preset risk level may be a high risk level, that is, when the preset risk level is lower than the preset risk level, the blockchain operation is considered as a low risk, and thus the blockchain operation may be directly confirmed.
In an embodiment, if the risk status satisfies a first condition, a second condition, or a third condition, the risk level represented by the risk status is equal to the preset risk level;
wherein the first condition is that a new node is added into the block chain;
the second condition is that the interval duration of block chain operations which are continuously performed twice in the block chain by a user corresponding to the block chain operation is less than a preset time threshold;
the third condition is that an operand value corresponding to the block chain operation exceeds an average operand value, where the average operand value is an average of operand values of a user corresponding to the block chain operation within a preset time.
In an embodiment, if the risk status satisfies a first condition, a second condition, or a third condition, the risk level represented by the risk status is higher than the preset risk level;
wherein the first condition is that a new node is added into the block chain;
the second condition is that the interval duration of block chain operations which are continuously performed twice in the block chain by a user corresponding to the block chain operation is less than a preset time threshold;
the third condition is that an operand value corresponding to the block chain operation exceeds an average operand value, where the average operand value is a mean value of operand values of a user corresponding to the block chain operation within a preset time.
Wherein, if there is a risk that exists when a new node is added in the block chain, the risk is determined to exist when the first condition is satisfied; if the interval duration is less than the predetermined time threshold, the blockchain operation may be risky, for example: repeating the operation or stealing the product by others, and thus, when the second condition is met, confirming that the risk exists; if the operand value corresponding to the blockchain operation exceeds the average operand value, this indicates that the operation may be abnormal, for example: the user's transaction amount exceeds the average value of the transaction amount for a certain period of time, and thus the risk is determined to exist when the third condition is satisfied.
Further, in a case where the risk state does not satisfy any of the first condition, the second condition, and the third condition, the risk level represented by the risk state is lower than a preset risk level. For example: and if the risk state indicates that no new node is added in the block chain, the risk state indicates that the interval duration of the block chain operation of the user corresponding to the block chain operation continuously performed twice in the block chain is greater than or equal to a preset time threshold, and the risk state indicates that the operand value corresponding to the block chain operation does not exceed the average operand value, the risk level represented by the risk state is lower than a preset risk level.
In the above embodiment, the risk level can be judged by whether a new node is added, the interval duration and the operand value, so that the safety of the block chain operation is higher. For example: if a new node is added into the block chain network, all transactions within a certain time are considered to have high risk, and the new node is prevented from doing harm; or, if the interval time between two transactions of the same user is less than 24 seconds, the risk of the second transaction is considered to be high; or, the transaction amount of a user exceeds the average value of the transaction amount of the user within a certain time, the risk is considered to be high.
It should be noted that, in the embodiment of the present invention, it is not limited to determine the risk level by whether a new node is added, an interval duration, and an operand, for example: the operand value corresponding to the blockchain operation may also be compared with the historical highest value to determine the risk level.
It should be noted that the present embodiment can also be applied to the embodiment shown in fig. 1, for example: if the risk state does not satisfy any of the first condition, the second condition, and the third condition, the risk state satisfies the preset state condition, and the same beneficial effect can be achieved.
As an optional implementation manner, in a case that at least one block is generated after the block chain generates the target block, performing a confirmation operation on the block chain operation includes:
and under the condition that N blocks are generated after the target block is generated by the block chain, confirming the block chain operation, wherein N corresponds to the risk level represented by the risk state, and the value of N is positively correlated with the risk level.
The value of N is positively correlated with the risk level, wherein the value of N is larger when the risk level is higher, and the value of N is smaller when the risk level is lower. Therefore, the value of N can be flexibly configured according to the risk level, so that the working efficiency is improved and the operation risk is reduced under the condition that the risk level is equal to or higher than the preset risk level. Preferably, the value range of N is 1 to 6, that is, the value of N can be determined in 1 to 6 according to the risk level.
In this embodiment, a plurality of risk levels including the preset risk level may be preset, and when the risk level indicated by the risk state is a certain risk level of the plurality of risk levels, the risk is considered to be high, and the block chain operation needs to be confirmed after the block chain is regenerated into another block, so as to ensure that the operation is not rolled back, thereby reducing the risk.
In this embodiment, the block chain operation can be confirmed under the condition that the risk level is lower than the preset risk level through the above method, so that the confirmation operation can be quickly performed under the condition of low risk, and the working efficiency can be improved.
