Figure 2 is a flow chart of a data verification method according to an embodiment of the present application. It is specifically a schematic diagram of the interaction process between the anchor cell and the control platform. The steps performed by the anchor cell in the flow chart can be arbitrarily modified. An anchor cell is implemented. As shown in Figure 2, the data verification method can include:

S201. The control platform sends a secondary node group request to the anchor cell.

S202: The anchor cell receives the secondary node group request sent by the control platform, and the secondary node group request includes the candidate secondary node group corresponding to the anchor cell.

The auxiliary node group request may include a auxiliary node group list, and the auxiliary node group list includes a plurality of candidate auxiliary node groups with the highest order of the auxiliary node group weight values.

The control platform selects multiple candidate secondary node groups with higher order of secondary node group weight values from all candidate secondary node groups, and uses the above-selected multiple candidate secondary node groups as candidate secondary node groups in the secondary node group list. .

For example, there are K candidate secondary node groups in the secondary node group list in the secondary node group request, and the terminal secondary node in each candidate secondary node group corresponds to the same anchor cell. That is, K anchor cells correspond to K candidate secondary node groups one-to-one. The control platform sends secondary node group requests to the K anchor cells corresponding to the K candidate secondary node groups respectively.

The control platform selects terminal auxiliary nodes based on auxiliary node groups. For example, each secondary node group contains ni terminal secondary nodes, and the ni terminal secondary nodes belong to the same cell. This cell is called the anchor cell corresponding to the above ni terminal secondary nodes.

As a possible implementation method, the control platform identifies the assistant node group through the assistant node group ID (Assistant Node GroupIDentity, ANG-ID). When the terminal auxiliary node moves or its position changes, the auxiliary node group list also needs to update the auxiliary node group in real time according to the mobile position of the terminal auxiliary node. Among them, each secondary node group contains the following information: secondary node group identification, anchor cell identification, contractor identification, and secondary node group list information. Among them, the contractor ID is used to represent the builder of the anchor cell base station. For example, in AB co-construction and sharing, the ID of contractor A is 00, and the ID of the base station of contractor B is 01.

S203. The anchor cell responds to the request of the secondary node group and determines whether the candidate secondary node group has the consensus confirmation capability by confirming whether the number of terminal secondary nodes with data verification qualifications in the candidate secondary node group meets the preset number.

It should be noted that the anchor cell responds to the secondary node group request and determines whether the candidate secondary node group has the ability to confirm consensus by determining the number of terminal secondary nodes with data verification qualifications in the candidate secondary node group. Specifically, the process of executing the above step S203 can be implemented through steps S301 to S305 as shown in FIG. 3 .

S204. If the anchor cell confirms that the number of terminal auxiliary nodes with data verification qualifications in the candidate auxiliary node group meets the preset number, it sends auxiliary node group confirmation information to the control platform. The auxiliary node group confirmation information is used to characterize the candidate auxiliary node. The group has the above-mentioned ability to confirm consensus.

Among them, when the anchor cell determines that the candidate secondary node group has the ability to confirm consensus, it sends secondary node group confirmation information to the control platform to indicate that the candidate secondary node group included in the secondary node group request sent by the control platform has the confirmation capability. Consensus ability.

S205: The control platform receives the secondary node group confirmation information sent by the anchor cell, and determines the candidate secondary node group corresponding to the secondary node group confirmation information in the secondary node group list as the secondary node group.

It should be noted that after receiving the secondary node group confirmation information sent by the anchor cell, the control platform determines the candidate secondary node group with the ability to confirm consensus and the anchor cell corresponding to the candidate secondary node group, and continues to store the information. In the secondary node group list, the candidate secondary node group is determined as the secondary node group.

S206. If the anchor cell confirms that the number of terminal secondary nodes with data verification qualifications in the candidate secondary node group does not meet the preset number, it sends secondary node group rejection information to the control platform. The secondary node group rejection information is used to characterize the candidate secondary node group. Inability to confirm consensus.

It should be noted that the anchor cell determines whether the candidate secondary node group has the ability to confirm consensus based on the number of terminal secondary nodes that are qualified for data verification included in each candidate secondary node group. In detail, if the number of terminal auxiliary nodes with data verification qualifications is less than the preset number, it is determined that the candidate auxiliary node group does not have the ability to confirm consensus. If the number of terminal auxiliary nodes with data verification qualifications is greater than or equal to the preset number, then It is determined that the candidate secondary node group has the ability to confirm consensus. Further, when the anchor cell determines that the candidate secondary node group does not have the ability to confirm consensus, it sends secondary node group rejection information to the control platform to indicate that the candidate secondary node group is included in the secondary node group request sent by the control platform. Inability to confirm consensus.

S207: The control platform receives the secondary node group rejection information sent by the anchor cell.

S208: The control platform updates and replaces the secondary node group corresponding to the secondary node group rejection information and the corresponding anchor in the secondary node group list based on the candidate secondary node group with the highest weight value among other secondary node groups other than the secondary node group list. Point community.

It should be noted that after receiving the secondary node group rejection information sent by the anchor cell, the control platform determines the secondary node group that does not have the ability to confirm consensus and the anchor cell corresponding to the secondary node group. From the secondary node deleted from the group list, and the candidate secondary node group with the highest weight value among other secondary node groups other than the secondary node group list is determined as the candidate secondary node group in the secondary node group list.

Among them, the list of secondary node groups is determined by the control platform based on the weight value of the secondary node group. Specifically, K candidate auxiliary node groups with the highest order of auxiliary node group weight values among all candidate auxiliary nodes are selected as candidate auxiliary node groups in the auxiliary node group list.

For example, step S208 will be described in detail, taking the list of secondary node groups including K candidate secondary node groups as an example. The auxiliary node group list includes K candidate auxiliary node groups. It can be understood that before the K candidate auxiliary node groups corresponding to the K anchor cells are verified for consensus capability, the auxiliary node group list includes K Candidate auxiliary node groups, where the K candidate auxiliary node groups are the K candidate auxiliary node groups with the highest order of the auxiliary node group weight values. If after confirming the consensus capability verification of the K candidate secondary node groups corresponding to K anchor cells, a secondary node group rejection message is received, the control platform will The candidate secondary node group is updated to the (K+1)th candidate secondary node group whose weight order of the candidate secondary node group is (K+1), and the candidate secondary node group corresponding to the secondary node group rejection information is removed from the secondary node group Delete from the list, and re-update the order of the weights of all candidate sub-section groups.

As a possible implementation, the weight value of the auxiliary node group is determined by the following formula (1):

Wgi＝[Wn×Ln+Wo×Lo+Ws×Ls]×Io, formula (1)

Among them, Wgi represents the weight value of the auxiliary node group, Wn represents the weight of the terminal auxiliary node, Ln represents the number level of the terminal auxiliary node, Wo represents the anchor cell resource occupancy rate weight, Lo represents the idle time occupancy level of the anchor cell, and Ws represents the terminal auxiliary node level. Node responsibility weight, Ls represents the historical responsibility level of the terminal auxiliary node, Io represents the anchor cell resource occupancy indicator, Wn, Ln, Wo, Lo, Ls and Io are all greater than or equal to 0, Ws is an integer greater than or equal to 1.

As a possible implementation manner in the above embodiment, Ln is related to the number ni of terminal secondary nodes. If the number of terminal auxiliary nodes ni is located in different intervals, the Ln value will be different. The more terminal auxiliary nodes (i.e. ni) the auxiliary node group contains, the larger Ln is. For example, ni<50, Ln=0, 50≤ni<100, Ln=1, 100≤ni<150, Ln=2 , ni≥150, Ln=3.

In detail, Lo is the idle time occupancy level of the anchor cell. It can be understood that the anchor cell is divided according to its idle time resource occupancy, and its resource occupancy is located in different intervals with different Lo values. In the interval with the highest resource usage, Lo takes 0. For example, if the anchor cell's idle time occupancy is greater than 70%, L0=0, the anchor cell's idle time occupancy level is between 50% and 70%, Lo=1, and the anchor cell's idle time occupancy level is less than 50%, Lo= 2.

Among them, the initial value of Ls is 0, and Io represents the anchor cell resource occupancy indication. It can be understood that when Lo is equal to 0, Io=0, and when Lo is not equal to 0, Io=1. The purpose of the above Io value is to temporarily not select the anchor cell as the secondary node group when the load of the anchor cell is high, so as to avoid further increasing the load of the anchor cell.

Furthermore, WS is greater than (Wn×Lnmax+Wo×Lomax), and Lnmax and Lomax are the maximum values that Ln and Lo can take.

Furthermore, when Ln, Lo or Ls changes, the value of Wgi also changes. Among them, Ln and Lo are sent to the control platform by the anchor cell, and the anchor cell periodically updates the values of Ln and Lo.

It should be noted that the control platform in this application can also process the received secondary node group confirmation information or secondary node group rejection information one by one as in the above embodiment, or can also process all secondary node group confirmation information or secondary node group rejection information. processed simultaneously.

For example, after verifying the confirmation consensus capabilities of K candidate secondary node groups, if (K-n) secondary node group confirmation information and n secondary node group rejection information are received, then the secondary node group rejection information will correspond to The n candidate auxiliary node groups are updated to the (K+n)th candidate auxiliary node group whose weight order of the candidate auxiliary node group is located at (K+n), and n corresponding to the rejection information of the n auxiliary node groups are The candidate auxiliary node group is deleted from the auxiliary node group list, and the order of the weights of all candidate auxiliary node groups is re-updated. This application does not limit the order in which the control platform processes the secondary node group confirmation information or the secondary node group rejection information and the number of simultaneous processes.

It can be understood that after one or more candidate secondary node groups corresponding to the secondary node group list are updated, if the corresponding candidate secondary node group in the secondary node group list needs to be deleted or added, the secondary node group request includes One or more candidate secondary node groups and corresponding anchor cells included in the secondary node group list will be updated, and an updated secondary node group request is sent to the updated anchor cell to determine the updated candidate secondary node group. The ability to confirm consensus.

It can be seen from the above embodiments that in the data verification method provided by the embodiments of the present application, the control platform first determines multiple candidate auxiliary node groups through the order of the weight values of the auxiliary node groups. Among them, multiple candidate secondary node groups each correspond to an anchor cell one-to-one. Each anchor cell then confirms the consensus capability of the corresponding candidate secondary node group, thereby determining the secondary node group. Therefore, the auxiliary node group and the terminal auxiliary node corresponding to the anchor cell determined based on the above data verification method of this application ensure the consensus confirmation ability of the auxiliary node group participating in the data verification consensus, that is, ensuring that the auxiliary node group corresponds to The anchor cell can contain a sufficient number of terminal secondary nodes qualified for data verification, thereby ensuring the reliability of the data verification process.

Figure 3 is a flow chart of a data verification method according to an embodiment of the present application. As shown in Figure 3, the data verification method is executed by the anchor cell, and may specifically include:

S301: From the M terminal auxiliary nodes included in the candidate auxiliary node group, determine the N terminal auxiliary nodes with the highest weight order of the terminal auxiliary nodes.

S302: Send terminal auxiliary node requests to N terminal auxiliary nodes to confirm that the terminal auxiliary node is qualified for data verification based on whether the terminal auxiliary node returns a confirmation result within a preset time. Among them, the terminal auxiliary node request is generated by the anchor cell according to the auxiliary node group request sent by the control platform, and the terminal auxiliary node request also includes preset wireless signal quality parameters. The preset wireless signal quality parameters are used to test whether the terminal auxiliary node Have data verification capabilities. Specifically, for a description of how the preset wireless signal quality parameters are used to test whether the terminal secondary node has the data verification capability, please refer to the specific implementation description of step S402 below.

It should be noted that when the preset number is N, after obtaining the terminal auxiliary node weights of all terminal auxiliary nodes in the candidate auxiliary node group, the anchor cell first determines from all terminal auxiliary nodes (i.e., M terminal auxiliary nodes). Output the N terminal auxiliary nodes with the highest weight order. The terminal auxiliary node request is then sent to the N terminal auxiliary nodes, so that the N terminal auxiliary nodes determine the data verification qualifications of their respective terminal auxiliary nodes.

Among them, the preset number N can be set according to needs. And in any implementation, when it is determined that the number M of terminal secondary nodes included in the candidate secondary node group is less than N, secondary node group rejection information is sent to the control platform.

As a possible implementation manner, the preset number N of terminal auxiliary nodes can be understood as the number of terminal auxiliary nodes that actually assume the function of the auxiliary node each time is N. N is obtained according to the following formula:

N=round up (b/K)+M0, formula (2)

Among them, b is the total number of auxiliary nodes required to participate in the data verification consensus each time, K is the number of auxiliary node groups required to participate in the data verification consensus each time, and M0 is the required terminal auxiliary node margin. The preset number N obtained through this method can prevent the terminal secondary node from moving to other anchor cells during the data verification consensus process and being unable to directly establish a connection with the anchor cell.

S303b. If it is confirmed that N1 terminal auxiliary nodes have data verification qualifications, and N1 is equal to N, it is determined that the candidate auxiliary node group has the ability to confirm consensus.

It should be noted that if the anchor cell receives the confirmation results returned by N terminal secondary nodes within the preset time, it means that the candidate secondary node group has the ability to confirm consensus, that is, the anchor cell can send the secondary node group to the control platform Confirm the message. If the anchor cell does not receive the confirmation results returned by N terminal secondary nodes within the preset time, it means that the candidate secondary node group does not have the ability to confirm consensus, that is, the anchor cell can send the secondary node group rejection message to the control platform.

S303a, if it is confirmed that N1 terminal secondary nodes are qualified for data verification, and N1 is less than N, determine whether the current number of requests is less than the preset number.

The number of requests refers to the number of times a terminal secondary node request is sent to multiple terminal secondary nodes at the same time.

S304. If the current number of requests is less than the preset number, determine the (N-N1) terminal auxiliary nodes with the highest weight order from the terminal nodes in the candidate auxiliary node group except the N terminal auxiliary nodes. and sends terminal secondary node requests to (N-N1) terminal secondary nodes.

S305, update N1 based on the number of terminal auxiliary nodes with data verification qualifications among the (N-N1) terminal auxiliary nodes, until the number of requests is equal to the preset number, or N1 is equal to N, or the terminal has been sent to all terminal auxiliary nodes. Secondary node request.

It should be noted that when the anchor cell receives a confirmation result returned by the terminal secondary node at the preset time and the number is less than the preset number N, the current anchor cell sends a terminal secondary node request to multiple terminal secondary nodes. Count the total number of requests to determine whether the total number of requests (i.e., the current request) has reached the preset number. If the current number of requests is greater than or equal to the preset number, it means that the candidate secondary node group does not have the ability to confirm consensus, that is, the anchor cell can send the secondary node group rejection message to the control platform.

Specifically, if the current number of requests is less than the preset number, and among the terminal nodes that can be excluding N terminal auxiliary nodes from the candidate auxiliary node group, select the (N-N1) terminal auxiliary nodes with the highest weight order In the case of terminal secondary nodes, send terminal secondary node requests to (N-N1) terminal secondary nodes, and update N1 and update based on the number of terminal secondary nodes among the (N-N1) terminal secondary nodes that are qualified for data verification. Number of requests. And judge the updated N1 and N as well as the updated number of requests and the preset number of times.

Specifically, if the current number of requests is less than the preset number, and the (N-N1) terminal nodes with the highest terminal auxiliary node weight order cannot be selected from the terminal nodes in the candidate auxiliary node group except N terminal auxiliary nodes, In the case of a secondary node, it means that the candidate secondary node group does not have the ability to confirm consensus, that is, the anchor cell can send the secondary node group rejection message to the control platform.

Among them, according to the number of terminal auxiliary nodes with data verification qualifications among the (N-N1) terminal auxiliary nodes, updating N1 can be understood as, if there are 2 terminal auxiliary nodes with data verification qualifications among the (N-N1) terminal auxiliary nodes. If the number is b, N1 is updated to (N1+b).

For example, if the anchor cell receives N confirmation results returned by N terminal secondary nodes among the candidate secondary nodes within the preset time Taw1, it will reply the secondary node group confirmation information to the control platform to confirm the N of the candidate secondary node group. A terminal auxiliary node serves as a terminal auxiliary node in this data verification consensus.

If the anchor cell only receives N1 secondary node confirmation messages in Taw1 (N1<N), then among the N terminal secondary nodes of the anchor cell, the terminal secondary node that replies with a rejection result and the terminal secondary node that does not have any reply will be Give up, that is, it cannot serve as the terminal's secondary node function (even if the subsequent process receives the secondary node confirmation message sent by the terminal, the process will be given up). This can be done by sending a terminal secondary node cancellation message to the terminal secondary node that is doing the abandonment process.

At the same time, the anchor cell selects the (N-N1) terminal auxiliary nodes with the highest weight order of the terminal auxiliary nodes according to the weight Wui of the terminal auxiliary node, and sends terminal auxiliary node requests to the (N-N1) terminal auxiliary nodes. And the counter Ci1 increases by 1, waiting for Taw1 to collect reply messages from (N-N1) terminal secondary nodes. If (N-N1) secondary node confirmation information is not collected, that is, the total number of secondary node confirmation messages received does not reach N. , then repeat the above steps of sending terminal auxiliary node requests to (N-N1) terminal auxiliary nodes and the determination steps after this step, continue to find alternative terminal auxiliary nodes according to the terminal auxiliary node weight Wui, and the counter round number Ci1 is increased by 1, Until N secondary nodes are found, a secondary node group confirmation message is returned to the control platform. Among them, Ci1 is the number of rounds of the anchor cell's terminal auxiliary node search counter, and the initial value is 0. Ci1 can be understood as the number of rounds used to record the anchor cell's search for the terminal auxiliary node.

Further, if the Ci1 value reaches the preset number of times, N secondary node terminals have not been found, or the anchor cell has sent terminal secondary node requests to all terminal secondary nodes in the candidate secondary node group, but has not received N secondary node terminals. The secondary node confirmation information, or the number of terminal secondary nodes in the secondary node group list under the candidate secondary node group is less than N, then the anchor cell corresponding to the candidate secondary node group sends secondary node group rejection information to the control platform.

Further, when the control platform receives the secondary node group rejection message sent by the secondary node anchor cell, the control platform sends the secondary node group rejection message to the candidate secondary node group, and reselects the candidate secondary node group according to the secondary node group weight value Wgi. , and sends a secondary node group request message to the updated candidate secondary node group.

Further, the control platform receives the secondary node group confirmation information sent by all candidate secondary node groups, and uses all candidate secondary node groups corresponding to the secondary node group confirmation information as all secondary node groups to complete the secondary node group and terminal secondary node assistance. Select.

Further, the control platform sends the determined secondary node group to the anchor cells corresponding to all secondary node groups in the secondary node group list. The list of secondary node groups includes the secondary node group IDs and anchor cell IDs of all secondary node groups participating in the data verification consensus work this time.

Figure 4 is a flow chart of a data verification method shown in this application according to an exemplary embodiment, which is specifically a schematic diagram of the interaction process between the anchor cell and the terminal secondary node. As shown in Figure 4, the data verification method may include:

S401: The anchor cell sends terminal secondary node requests to N secondary terminal nodes.

S402: The terminal auxiliary node determines whether the terminal auxiliary node has data verification qualifications.

S403: The terminal secondary node sends a confirmation result confirming that the terminal secondary node has data verification qualifications to the anchor cell.

S404: The anchor cell confirms whether the terminal auxiliary node is qualified for data verification based on the confirmation result returned by the terminal auxiliary node within a preset time.

Wherein, the terminal auxiliary node request includes preset wireless signal quality parameters, and the preset wireless signal quality parameters are used to test whether the terminal auxiliary node has data verification capabilities.

It can be seen from the above embodiments that the specific interaction process between the anchor cell and the terminal auxiliary node in the data verification method from step S302 to step S304 in the embodiment of the present application. With reference to Figure 3 and Figure 4, the embodiment of the present application determines whether N candidates in the candidate secondary node group have data verification qualifications by interacting between the anchor cell and the terminal secondary node through the terminal secondary node request and confirmation results. Terminal auxiliary node to determine whether the candidate auxiliary node group has the ability to confirm consensus.

Specifically, the anchor cell summarizes the confirmation results sent by the terminal secondary node, and determines the number of summarized confirmation results. Each time the anchor cell determines that the number of confirmation results is less than the preset number N, it re-determines the number of terminal auxiliary nodes and the number of terminal auxiliary nodes to which the terminal auxiliary node request is sent again based on the auxiliary node weights of the remaining terminal auxiliary nodes. If the number of confirmation results does not reach N, the above-mentioned process of determining the number of confirmation results, the number of requests, and sending requests to the terminal secondary node will continue until the number of requests equals the preset number, or the number of aggregated confirmation results equals N, or all requests have been sent to all The terminal secondary node has sent a terminal secondary node request.

As a possible implementation manner, the above step S402 can be implemented in the following manner. The preset wireless signal quality parameters are set to the preset signal receiving power and the preset signal to interference plus noise ratio, where the preset signal to interference plus noise ratio refers to the prestored strength of the received useful signal and the received interference The ratio of signal (noise and interference) strengths. At any terminal auxiliary node, it is determined that the reference signal receiving power corresponding to any terminal auxiliary node is greater than or equal to the preset signal receiving power, and the signal to interference plus noise ratio corresponding to any terminal auxiliary node is greater than or equal to the preset signal to interference plus noise ratio. In the case of , the terminal secondary node sends the confirmation result to the anchor cell. When any terminal auxiliary node determines that the reference signal received power corresponding to any terminal auxiliary node is less than the preset signal reception power, or the ratio of the signal to interference plus noise corresponding to any terminal auxiliary node is less than the preset signal to interference plus noise ratio Under this condition, the terminal secondary node does not send a reject message to the anchor cell.

It should be noted that the above terminal secondary node does not send a rejection message to the anchor cell, which can be understood as sending neither a confirmation result nor a rejection result to the anchor cell.

Figure 5 is a flow chart of a data verification method shown in this application according to an exemplary embodiment, which is specifically a schematic diagram of the interaction process of the control platform, anchor cell, terminal auxiliary node and master node. As shown in Figure 5, the data Verification methods can include:

S501. The control platform sends a data verification request to the anchor cell and the master node.

The data verification request may be a data verification request generated by the control platform based on the data to be verified. The data to be verified may be network quality data formed by the control platform summarizing measurement reports within a certain period of time.

For example, a data verification request may be formed based on the network quality data and the recorded timestamp data related to the network quality data.

S502: The master node receives the data verification request sent by the control platform, and verifies the data to be verified to generate a third verification result.

S503. The master node generates a third verification confirmation request based on the third verification result.

It should be noted that the control platform sends data verification requests to all master nodes so that all master nodes can verify the data to be verified. Among them, the data verification request includes data to be verified.

As a possible way, steps S502 and S503 can be implemented in the following specific ways. The master node performs data verification and block packaging on the information in the data verification request, and generates a third verification confirmation request with the block data, block summary, timestamp, block serial number and block information after block packaging and verification. .

In some embodiments, the third verification confirmation request is encrypted before being sent.

S504. The first anchor cell receives the data verification request sent by the control platform.

Among them, the first anchor cell is the anchor cell corresponding to any secondary node group.

S505: The first anchor cell sends the data verification request to the terminal secondary node corresponding to the first anchor cell.

It can be understood that the control platform does not directly send the data verification request to the terminal auxiliary node, but forwards it to the terminal auxiliary node corresponding to the first anchor cell through the first anchor cell, thereby reducing the time for the control platform to send data to be verified. frequency.

S506: The terminal secondary node receives the data verification request sent by the first anchor cell.

S507: The terminal auxiliary node verifies the data to be verified in the data verification request and generates the first verification result.

S508: The terminal secondary node sends the first verification result to the first anchor cell.

S509: The first anchor cell receives the first verification result returned by the terminal secondary node corresponding to the first anchor cell to determine the first verification confirmation request.

It can be understood that each anchor cell obtains the first verification confirmation request after summarizing the verification results returned by all corresponding terminal secondary nodes. For example, when a first anchor cell includes N terminal auxiliary nodes, after the N terminal auxiliary nodes verify the to-be-verified data, the N terminal auxiliary nodes then send their respective verification results to the corresponding first anchor point. Cell, the first anchor cell obtains the first verification confirmation request after summarizing the N verification results returned by the N terminal secondary nodes. The first verification confirmation request includes the first verification result.

In some embodiments, the first verification result includes block data, block digest, timestamp, block sequence number and block information formed after the terminal auxiliary node packages and verifies the data block.

Optionally, the first verification result may include encrypted information for the first verification result.

S510: The first anchor cell sends the first verification confirmation request to the terminal secondary node corresponding to the first anchor cell.

S511. The first anchor cell sends the first verification confirmation request to the master node.

S512. The master node confirms the consensus on the first verification result in the first verification confirmation request.

S513. The terminal secondary node confirms consensus on the first verification result in the first verification confirmation request.

It can be understood that the first anchor cell obtains the first verification confirmation request based on aggregating the verification results of all terminal secondary nodes corresponding to the first anchor cell. And the first verification confirmation request is sent to the master node and the terminal slave node to complete the confirmation consensus of the first verification result between the master node and the terminal slave node.

It should be noted that data transmission between terminal secondary nodes corresponding to each anchor cell is also forwarded through the anchor cell. In detail, the first anchor cell sends the first verification confirmation request to the second anchor cell, all primary nodes and the terminal secondary nodes corresponding to the first anchor cell, so that all terminal secondary nodes and all primary nodes respond to the first The verification result confirms the consensus, in which the first anchor cell is the anchor cell corresponding to any secondary node group, and the second anchor cell is any anchor cell except the first anchor cell. The first anchor cell receives the second verification confirmation request sent by the second anchor cell, and the second verification confirmation request contains the second verification result of the to-be-verified data of the terminal secondary node corresponding to the second anchor cell; the first anchor cell will The second verification confirmation request is sent to the terminal auxiliary node corresponding to the first anchor cell, so that the terminal auxiliary node corresponding to the first anchor cell confirms consensus on the second verification result.

S514. The master node sends the third verification confirmation request to the first anchor cell.

It should be noted that the master node also sends the third verification confirmation request to the second anchor cell, so that the terminal secondary node corresponding to the second anchor cell confirms consensus on the third verification result in the third verification confirmation request. In other words, the master node sends the third verification confirmation request to all anchor cells, and all anchor cells are composed of the first anchor cell and the second anchor cell.

S515. The first anchor cell receives the third verification confirmation request sent by the master node.

S516: The first anchor cell sends the third verification confirmation request to the terminal secondary node corresponding to the first anchor cell.

S517: The terminal secondary node confirms the consensus on the third verification result in the third verification confirmation request.

The master node may send the third verification confirmation request to all anchor cells participating in data verification, that is, the first anchor cell and the second anchor cell.

It should be noted that the master node reduces the number of data transmissions by the master node by sending the third verification confirmation request to the anchor cell.

Wherein, when there are multiple master nodes, the master node forwards the third verification confirmation request of the master node to other master nodes, so that the other master nodes confirm the consensus on the third verification result in the third verification confirmation request.

For example, as shown in Figure 6 and Figure 7. Figure 6 is a schematic diagram of data links between nodes in the related art. Figure 7 is a schematic diagram of data links between nodes in this embodiment of the present application. Take Figure 6 and Figure 7, both of which have 2 primary nodes and 6 terminal secondary nodes, as an example. Among them, the main nodes in Figure 6 are Z1’ and Z2’, and the terminal auxiliary nodes are F1’, F2’, F3’, F4’, F5’ and F6’. In Figure 7, the main nodes are Z1 and Z2, the terminal auxiliary nodes are F1, F2, F3, F4, F5 and F6, and the anchor cells M1 and M2. In the data verification consensus process, when confirming the consensus on the verification result of the master node Z1' in the related technology, a verification confirmation request needs to be sent to each secondary node and each master node, that is, it has to be sent 7 times, and similarly, During the data verification consensus process, each node Z1', Z2', F1', F2', F3', F4', F5' and F6' sends verification result confirmation requests 7 times before all other nodes can complete the verification of the node. Confirmation consensus process of verification results. In the embodiment of this application, the master nodes are Z1 and Z2, and they only need to send three verification confirmation requests to complete the confirmation consensus of the verification results of the master node by the other nodes. And in the embodiment of this application, the auxiliary nodes F1, F2, F3, F4, F5 and F6 only need to send a verification confirmation request to complete the verification results of the node by all other nodes (all nodes except this node). Confirm consensus. It can be seen from this that the data verification method provided by this application can reduce the number of communications between each auxiliary node and the master node in the data verification consensus process to receive and send data, reduce the complexity of the data verification consensus process, thereby reducing the terminal Power consumption and latency of the data consensus process.

It should be noted that, in this embodiment, the anchor cell and the terminal secondary node corresponding to the anchor cell can pass steps S201 to step S208 and/or steps S301 to step S305 and/or steps in the above data verification method provided. Obtained from S401 to step S404. This is to further ensure that the anchor cell participating in data verification has the ability to confirm consensus, and that the terminal auxiliary node corresponding to the anchor cell has the ability to verify data.

In some embodiments, the main node is jointly built by operators and is responsible for block generation and block storage. The terminal auxiliary node selects terminals with terminal affordability in the network, that is, based on terminal capabilities, terminal willingness, terminal power and historical participation. Comprehensive selection based on circumstances and other factors. The selected terminal auxiliary node participates in the data block generation verification in the data verification process. Through the cooperation of the main node and the terminal auxiliary node, trusted storage of co-constructed and shared network quality information is realized.

It should be noted that in the above embodiments, after all master nodes and terminal auxiliary nodes generate a consensus on the verification results in the verification confirmation request, they generate corresponding confirmation consensus results and send them directly to the control platform. Among them, the confirmation consensus result corresponding to each node is recorded as Cji, and the node is any master node and any terminal auxiliary node. The verification confirmation request includes the first verification confirmation request generated by the first anchor cell based on the first verification result, The second anchor cell generates a second verification confirmation request based on the second verification result, and the master node generates a third verification confirmation request based on the third verification result. The second anchor cell is any anchor cell except the first anchor cell. .

In some embodiments, after executing steps S510 to S517, the control platform determines the target consensus result based on the received confirmation consensus results sent by all terminal secondary nodes and all master nodes.

For example, after receiving the confirmed consensus results sent by all master nodes and terminal auxiliary nodes, the control platform verifies the verification results of other nodes by each node to generate a confirmed consensus result set {Cij} (where Cji is the node The confirmed consensus result of j on node i, and j≠i). Based on the verification set {Cij} sent by each node, the control platform determines the master node with the largest sum of confirmation consensus results for the master node from other nodes in each master node, and sets the verification result corresponding to the largest master node as The target consensus result, and the control platform broadcasts the target consensus result to all master nodes, so that all master nodes store the target consensus result. In some embodiments, the target consensus result is typically used as the best block data.

Through the above embodiment, after the control platform generates a data verification request based on the data to be verified, it sends the generated data verification request to all anchor cells and all master nodes. All anchor cells will then receive the data verification request and forward it to all terminal secondary nodes corresponding to the respective anchor cells. This completes the verification that all terminal secondary nodes and all primary nodes have data to be verified. After the verification is completed, on the one hand, the master node will send the verification results generated by the verification of the data to be verified to other master nodes and all anchor cells to complete the confirmation of the verification results of all master nodes by all master nodes and all terminal secondary nodes. consensus. At the same time, all terminal auxiliary nodes send the verification results generated by their own data verification to be verified to their corresponding anchor cells. On the other hand, each anchor cell summarizes all verification results sent by all terminal secondary nodes corresponding to the received anchor cell, thereby determining the verification determination request corresponding to each anchor cell. All anchor cells then send their corresponding verification confirmation requests to other anchor cells, all primary nodes, and all terminal secondary nodes corresponding to the anchor cells to complete the verification of all primary nodes and all terminal secondary nodes on all terminal secondary nodes. Confirm consensus of verification results.
