Background Art

[0002] As a new type of data sharing technology, blockchain has promoted the construction of energy Internet with its unique trust building mechanism, formed a decentralized interactive mode of energy flow, information flow and value flow, and realized point-to-point value transfer without the need for a third-party trust mechanism. At the same time, the smart contract function based on blockchain technology makes the execution of programs such as energy trading, demand response, and e-commerce more intelligent and automated. The consensus mechanism is the core of the blockchain, and its role is to verify the authenticity and consistency of data in a decentralized distributed network environment. The consensus mechanism ensures that all nodes make all transactions in a reliable manner without relying on central coordination.

[0003] Among them, the RAFT consensus mechanism is an algorithm that can achieve strong consistency in distributed systems and is very suitable for application scenarios where blockchain nodes change dynamically. However, in the RAFT consensus mechanism currently used by the power blockchain, all nodes need to participate in the process of selecting the leader node and count the number of votes.

[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] The leader node determination method of the power transaction blockchain based on the RAFT consensus mechanism and the information processing method of the power transaction blockchain based on the RAFT consensus mechanism provided in the embodiment of the present application can be applied to the power transaction blockchain based on the RAFT consensus mechanism, and executed by the corresponding nodes in the power transaction blockchain. Computer devices such as terminals and servers can constitute nodes of the power transaction blockchain. Among them, the terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, and portable wearable devices, and the server can be implemented as an independent server or a server cluster composed of multiple servers.

[0042] The method provided in this application is described in detail below in conjunction with embodiments and corresponding drawings.

[0043] In one embodiment, Figure 1 As shown, a method for determining a leader node of a power trading blockchain based on a RAFT consensus mechanism is provided, comprising the following steps:

[0044] Step S101, in response to the triggering of the leader election event, sends a voting request and the current reliability assessment value of the node to other nodes of the power trading blockchain, so that other nodes that receive the voting request can compare their current reliability assessment value with the current reliability assessment value of the node.

[0045] Among them, for the triggering of the leader election event, specifically, in the power trading blockchain based on the RAFT consensus mechanism, if the follower node does not receive the heartbeat signal from the leader node within the set timeout period, the follower node may consider that some changes have occurred in the server cluster network at this time. Possible situations include the server crash of the leader node, network failure, the end of the term of the leader node and the new leader node has not yet been determined. At this time, the follower node can determine that the leader election event has been triggered. The follower node responds to the triggering of the leader election event, actively initiates a leader election, increases the current term (term), and can change the identity of this node to a candidate node. Then, this node can send voting requests and the current reliability assessment value of this node to other nodes in the power trading blockchain in parallel. Other nodes that receive the voting request compare their current reliability assessment value with the received current reliability assessment value of the aforementioned node.

[0046] The reliability evaluation value of each node in the power transaction blockchain is calculated based on the cumulative value of the historical successful transaction volume of each node, the node stability factor, the cumulative value of the historical error transaction volume, and the node penalty factor. Specifically, for the reliability evaluation value of each node, in one embodiment, before sending a voting request and the current reliability evaluation value of the node to other nodes in the power transaction blockchain in step S101, the reliability evaluation value can be calculated by the following steps, specifically including:

[0047] Obtain the historical cumulative value of successful transaction volume, node stability factor, historical cumulative value of error transaction volume and node penalty factor of this node; calculate the positive integral part of reliability according to the product of the cumulative value of historical successful transaction volume and the node stability factor, and calculate the negative integral part of reliability according to the product of the cumulative value of historical error transaction volume and the node penalty factor; calculate the current reliability assessment value of this node according to the positive integral part of reliability and the negative integral part of reliability.

[0048] In this embodiment, the reliability evaluation value of this node is calculated by two parts, one is the positive integral part of reliability, and the other is the negative integral part of reliability. The positive integral part of reliability is calculated based on the product of the cumulative value of the historical successful transaction volume of this node and the node stability factor, and the negative integral part of reliability is calculated based on the product of the cumulative value of the historical error transaction volume of this node and the node penalty factor. They can be expressed by the following formulas:

[0049] R i =αV s -βV w

[0050] Among them, R i represents the current reliability evaluation value of the i-th node in the power transaction blockchain, αV s Represents the positive integral of reliability, βV w Represents the negative integral of reliability, α and V s Represent the node stability factor and the cumulative value of historical successful transactions, β and V respectively w They represent the node penalty factor and the cumulative value of historical error transactions, respectively. The cumulative value of historical successful transactions is the cumulative historical transaction volume of successful transactions of the node, and the cumulative value of historical error transactions is the cumulative transaction volume involved in the node due to error information. The node stability factor is used to characterize the stability of the node, and the node penalty factor is used to characterize the corresponding penalty level when the node generates an error behavior. Using the above formula, each node in the power transaction blockchain can calculate its current reliability assessment value and use it for comparison between nodes.

[0051] Further, for the calculation of the reliability evaluation value as described above, in some embodiments, the node stability factor is determined according to the ratio of the normal transaction duration of the node to the total transaction duration of the power transaction blockchain. Specifically, in this embodiment, the node stability factor α can be expressed by the following formula:

[0052]

[0053] Among them, N i It represents the normal transaction duration of the node i (such as the number of days that the node i participates in the electricity market transaction in the blockchain and does not exit due to failures, etc.), and N represents the total transaction duration of the electricity transaction blockchain (such as the total number of days that the electricity transaction blockchain has participated in the electricity market transaction).

[0054] Further, for the calculation of the reliability evaluation value as described above, in some embodiments, the node penalty factor is determined according to the preset evaluation value interval in which the historical reliability evaluation value of the node is located. Specifically, in this embodiment, the node penalty factor β can be expressed in the form of a piecewise function based on the historical reliability evaluation value, that is, each preset evaluation value interval corresponds to a node penalty factor β, and when a node with a high historical reliability evaluation value generates an erroneous behavior, the corresponding penalty factor is also large. The historical reliability evaluation value can specifically be the previous reliability evaluation value of the node, which can be specifically expressed as:

[0055]

[0056] Among them, β1,…,β j For each preset evaluation value interval ([0,R1],…,[R j-1 ,R j ]) The corresponding node penalty factor is generally β1<…,<β j , R1<…,<R j is the boundary value of the corresponding evaluation value interval.

[0057] Step S102, when receiving a comparison result from other nodes that their current reliability evaluation values ​​are lower than the current reliability evaluation value of the current node, determining to vote for the current node;

[0058] In this step, this node can receive the reliability evaluation value comparison results fed back by other nodes. If the other node finds that the current reliability evaluation value of the aforementioned node (the node that sends the voting request) is higher than the current reliability evaluation value of the other node itself, the other node will feedback the comparison result to the aforementioned node, and the other node will withdraw from this round of leader node election and become a follower node. When this node receives the comparison result fed back by other nodes that its current reliability evaluation value is lower than the current reliability evaluation value of this node, it will vote for itself, thereby continuously accumulating votes.

[0059] Step S103, determining the number of votes of the node;

[0060] In this step, the node can determine its own number of votes after receiving the comparison results fed back by other nodes.

[0061] Step S104: If this node is the only node with the highest number of votes in this round of leader election, or if this node is one of the nodes with the highest number of votes in this round of leader election and the time of determining the number of votes is the earliest, then this node is determined as the leader node of the power trading blockchain.

[0062] In this step, the leader node of the power trading blockchain can be finally determined by the number of votes. If this node is the only node with the highest number of votes in this round of leader election, then this node will be determined as the leader node of the power trading blockchain; if there are multiple nodes with the highest number of votes in this round of leader election, if this node belongs to one of them and the number of votes is determined the earliest, then this node will be determined as the leader node of the power trading blockchain. Once the leader node in the power trading blockchain is determined, it will send confirmation information to other nodes, the leader node selection process ends, and other nodes will switch to follower status.

[0063] The above-mentioned method for determining the leader node of the power trading blockchain based on the RAFT consensus mechanism responds to the triggering of the leader election event, sends a voting request and the current reliability evaluation value of the node to other nodes of the power trading blockchain, so that other nodes that receive the voting request compare their current reliability evaluation value with the current reliability evaluation value of the node, which is calculated according to the historical successful transaction volume accumulation value, node stability factor, historical error transaction volume accumulation value and node penalty factor of each node, and then when receiving the comparison result that the current reliability evaluation value of the node is lower than the current reliability evaluation value of the node, it is determined to vote for the node, and then the number of votes of the node is determined. If the node belongs to the only node with the highest number of votes in this round of leader election or the node belongs to one of the nodes with the highest number of votes in this round of leader election and the number of votes is determined the earliest, the node is determined as the leader node of the power trading blockchain. The scheme reliably simplifies the leader node election process of the power trading block through reliability evaluation, comparison and self-voting, improves the efficiency of determining the leader node in the RAFT consensus mechanism, and can also avoid the election failure of the leader node in the traditional technology due to the significant increase in complexity.

[0064] In one embodiment, Figure 2 As shown, a method for processing information of a power transaction blockchain based on a RAFT consensus mechanism is provided, which can be applied to the auditor node of the power transaction blockchain as described above, and the method includes the following steps:

[0065] Step S201, obtaining information related to the leader node in the power transaction blockchain as information to be reviewed; the power transaction blockchain determines the leader node according to the method described above;

[0066] Step S202: If the audit result of the information to be audited is failure to pass the audit, the node related to the information to be audited in the power trading blockchain is determined as a malicious node and the reliability evaluation value of the malicious node is updated, and a new round of leader election event is triggered and the malicious node is withdrawn from the new round of leader election.

[0067] Specific, combined Figure 3This embodiment is explained. After the leader node in the power transaction blockchain is determined, the consensus work begins. Among them, when the power market transaction is completed, the transaction information can be entered first and reviewed by the reviewer node (the transaction information can correspond to the information related to the leader node), and the reviewer node sends it to the leader node after verification; among them, for the completed log information sent by the leader node to the follower node and the currently submitted new log information (these log information can correspond to the information related to the leader node), it is also necessary to be verified by the reviewer node according to the timestamp. If the information is consistent with the previous verified information of the same transaction, the reviewer node submits the new log entry to the audit node log directory. If the information is inconsistent, that is, the audit result is that the audit fails, the transaction process and results of the entry log need to be further verified and processed, and at the same time, the nodes in the power transaction blockchain related to the information to be audited, that is, The leader node is determined to be a malicious node, and the reliability of the malicious node is evaluated in the manner disclosed in the aforementioned embodiment, and a new round of leader election events is triggered, and the malicious node is withdrawn from the new round of leader election; wherein, the storage log content of the elected leader node also needs to be checked by the auditor node as information related to the leader node, and the auditor node checks according to the timestamp, term of office and transaction results. If there are inconsistent entries, that is, the audit result is failure to pass the audit, then the auditor node determines that the current leader node election is invalid, and determines the current leader node as a malicious node. At the same time, the reliability of the malicious node is evaluated in the manner disclosed in the aforementioned embodiment, and a new round of leader election events is triggered, and the malicious node is withdrawn from the new round of leader election.

[0068] The scheme of the above-mentioned embodiment adds an auditor node in the power trading blockchain to verify information such as information copied to the leader node and information copied from the leader node to the follower node, so as to prevent the influence of malicious nodes, thereby overcoming the defects of the original RAFT consensus mechanism that cannot adapt well to the consensus requirements of the existence of malicious nodes and lacks the prevention and processing of malicious nodes. It is conducive to giving full play to its advantages in participating in power trading, promoting the application of blockchain technology in power trading, and helping to deepen the reform of the power market.

[0069] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
