The control platform 12 is capable of performing the following steps in the data verification method: step S201, step S206, step S209 to step S211 in the data verification method shown in fig. 2, all of step S301 to step S305 shown in fig. 3, and step S501 shown in fig. 5. The data verification device may be, for example, a management layer software integrated system for implementing different functional control requirements.

In some embodiments, the terminal auxiliary node 13 may be a data verification device configured to perform the data verification method as shown in fig. 10 provided by the embodiment of the present application. The terminal auxiliary node 13 can execute the following steps in the data verification method: step S402 and step S404 in the data verification method shown in fig. 4, step S506 to step S508, step S513, step S517 shown in fig. 5.

The master node 14 is capable of performing the following steps in the data verification method: as shown in fig. 5, step S502, step S503, step S512, and step S514 in the data verification method. The data verification device may specifically be a device that is commonly set up by a plurality of operators and is capable of taking charge of data block generation and data block storage.

Fig. 2 is a flowchart of a data verification method according to an embodiment of the present application, which is specifically a schematic diagram of an interaction process between an anchor cell and a control platform, wherein steps performed by the anchor cell in the flowchart may be performed by any one of the anchor cells. As shown in fig. 2, the data verification method may include:

s201, the control platform sends a secondary node group request to the anchor point cell.

S202, the anchor point cell receives an auxiliary node group request sent by the control platform, wherein the auxiliary node group request comprises candidate auxiliary node groups corresponding to the anchor point cell.

Wherein the secondary node group request may include a secondary node group list including a plurality of candidate secondary node groups with a leading bit order of secondary node group weight values.

The control platform selects a plurality of candidate auxiliary node groups with the front bit sequence of the auxiliary node group weight value from all the candidate auxiliary node groups, and takes the selected plurality of candidate auxiliary node groups as candidate auxiliary node groups of an auxiliary node group list.

Illustratively, the auxiliary node group list in the auxiliary node group request has K candidate auxiliary node groups, and the terminal auxiliary node in each candidate auxiliary node group corresponds to the same anchor cell. That is, the K anchor cells are in one-to-one correspondence with the K candidate secondary node groups. And the control platform respectively sends auxiliary node group requests to K anchor point cells corresponding to the K candidate auxiliary node groups.

And the control platform selects the terminal auxiliary node by taking the auxiliary node group as a unit. For example, each auxiliary node group includes ni terminal auxiliary nodes, and the ni terminal auxiliary nodes belong to the same cell, which is called an anchor cell corresponding to the ni terminal auxiliary nodes.

As one possible implementation, the control platform identifies the secondary node group by a secondary node group identification (Assistant Node Group IDentity, ANG-ID). When the terminal auxiliary node moves, namely the position changes, the auxiliary node group list also needs to update the auxiliary node group in real time according to the moving position condition of the terminal auxiliary node. Wherein each secondary node group contains the following information: auxiliary node group identification, anchor point cell identification, contractor identification and auxiliary node group list information. The contractor identifier is used for characterizing the constructor of the anchor cell base station, for example, in the AB co-construction sharing, the A contractor identifier is 00, and the B contractor base station identifier is 01.

S203, the anchor point cell responds to the auxiliary node group request and determines whether the candidate auxiliary node group has the capability of confirming consensus by confirming whether the number of terminal auxiliary nodes with data verification qualification in the candidate auxiliary node group meets the preset number.

It should be noted that, in response to the secondary node group request, the anchor cell determines whether the candidate secondary node group has a capability of confirming consensus by determining the number of terminal secondary nodes with data verification qualification in the candidate secondary node group. Specifically, the process of executing the above step S203 may be realized by steps S301 to S305 as shown in fig. 3.

S204, if the anchor point cell confirms that the number of the terminal auxiliary nodes with data verification qualification in the candidate auxiliary node groups meets the preset number, auxiliary node group confirmation information is sent to the control platform, and the auxiliary node group confirmation information is used for representing that the candidate auxiliary node groups have the confirmation consensus capability.

And the anchor point cell sends auxiliary node group confirmation information to the control platform under the condition that the candidate auxiliary node group has the confirmation consensus capability, so as to indicate that the candidate auxiliary node group contained in the auxiliary node group request sent by the control platform has the confirmation consensus capability.

S205, the control platform receives the auxiliary node group confirmation information sent by the anchor point cell, and determines candidate auxiliary node groups corresponding to the auxiliary node group confirmation information in the auxiliary node group list as auxiliary node groups.

After receiving the auxiliary node group confirmation information sent by the anchor point cell, the control platform determines a candidate auxiliary node group with confirmation consensus capability and an anchor point cell corresponding to the candidate auxiliary node group from the anchor point cell, and continuously stores the candidate auxiliary node group and the anchor point cell in an auxiliary node group list, namely, determines the candidate auxiliary node group as an auxiliary node group.

S206, if the anchor point cell confirms that the number of the terminal auxiliary nodes with data verification qualification in the candidate auxiliary node group does not meet the preset number, sending auxiliary node group rejection information to the control platform, wherein the auxiliary node group rejection information is used for representing that the candidate auxiliary node group does not have the capability of confirming consensus.

It should be noted that, the anchor cell determines whether each candidate auxiliary node group has the capability of confirming consensus according to the number of terminal auxiliary nodes with data verification qualification included in the candidate auxiliary node group. In detail, if the number of the terminal auxiliary nodes with the data verification qualification is smaller than the preset number, the candidate auxiliary node group is determined to have no capability of confirming the consensus, and if the number of the terminal auxiliary nodes with the data verification qualification is larger than or equal to the preset number, the candidate auxiliary node group is determined to have the capability of confirming the consensus. Further, if the anchor cell determines that the candidate auxiliary node group does not have the capability of confirming the consensus, auxiliary node group rejection information is sent to the control platform to indicate that the candidate auxiliary node group contained in the auxiliary node group request sent by the control platform does not have the capability of confirming the consensus.

S207, the control platform receives auxiliary node group rejection information sent by the anchor point cell.

And S208, the control platform updates and replaces the auxiliary node group corresponding to the auxiliary node group rejection information and the corresponding anchor point cell in the auxiliary node group list according to the candidate auxiliary node group with the forefront auxiliary node group weight value bit sequence except the auxiliary node group list.

After receiving the auxiliary node group rejection information sent by the anchor point cell, the control platform determines an auxiliary node group which does not have the capability of confirming consensus and an anchor point cell corresponding to the auxiliary node group from the anchor point cell, deletes the auxiliary node group from the auxiliary node group list, and determines one candidate auxiliary node group with the forefront auxiliary node group weight value bit sequence except the auxiliary node group list as a candidate auxiliary node group in the auxiliary node group list.

The auxiliary node group list is determined by the control platform according to the auxiliary node group weight value. Specifically, K candidate auxiliary node groups with the front bit sequence of the auxiliary node group weight value in all the candidate auxiliary nodes are selected as candidate auxiliary node groups in the auxiliary node group list.

Illustratively, step S208 is described in detail taking the example that the auxiliary node group list includes K candidate auxiliary node groups. The auxiliary node group list includes K candidate auxiliary node groups, which may be understood as including K candidate auxiliary node groups in the auxiliary node group list before performing confirmation and consensus capability verification on K candidate auxiliary node groups corresponding to the K anchor point cells, where the K candidate auxiliary node groups are K candidate auxiliary node groups with a front bit sequence of an auxiliary node group weight value. If 1 auxiliary node group rejection information is received after the confirmation consensus capability verification is performed on K candidate auxiliary node groups corresponding to the K anchor point cells, the control platform updates the candidate auxiliary node groups corresponding to the auxiliary node group rejection information in the auxiliary node group list to be the (K+1) th candidate auxiliary node group with the candidate auxiliary node group weight bit sequence being positioned in (K+1), and deletes the candidate auxiliary node groups corresponding to the auxiliary node group rejection information from the auxiliary node group list and updates the bit sequences of all the candidate auxiliary node group weights again.

As one possible implementation, the secondary node group weight value is determined by the following formula (1):

wgi = [ Wn×Ln+Wo×Lo+Ws×ls ] ×Io, equation (1)

Wherein Wgi represents an auxiliary node group weight value, wn represents a terminal auxiliary node weight, ln represents a terminal auxiliary node number grade, wo represents an anchor point cell resource occupancy weight, lo represents an anchor point cell idle occupancy grade, ws represents a terminal auxiliary node acting weight, ls represents a terminal auxiliary node historical bearing condition grade, io represents an anchor point cell resource occupancy indication, both Wn, ln, wo, lo, ls and Io are greater than or equal to 0, and Ws is an integer greater than or equal to 1.

As a possible implementation of the above embodiment, ln is related to the number ni of terminal auxiliary nodes. And if the number ni of the auxiliary nodes of the terminal is in different intervals, ln values are different. The greater the number of terminal secondary nodes (i.e., ni) contained by the secondary node group, the greater Ln, 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 rate level of the anchor cell, which can be understood as dividing according to the idle time resource occupancy rate of the anchor cell, where the resource occupancy rates are located in different intervals and have different Lo values. And when the resource occupancy rate is the highest, lo takes 0. For example, the occupancy rate of the anchor cell is greater than 70% when the anchor cell is idle, l0=0, the occupancy rate level of the anchor cell is between 50% and 70%, lo=1, the occupancy rate level of the anchor cell is less than 50%, lo=2.

Where Ls has an initial value of 0, io represents an anchor cell resource occupancy indication, and it can be understood that io=0 when Lo is equal to 0 and io=1 when Lo is not equal to 0. The purpose of the Io value is to temporarily not select the anchor cell as the auxiliary node group when the load of the anchor cell is high, so as to avoid further increasing the load of the anchor cell.

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

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

In the embodiment of the present application, the control platform may process the received auxiliary node group acknowledgement information or auxiliary node group rejection information one by one, or may process all auxiliary node group acknowledgement information or auxiliary node group rejection information simultaneously.

Illustratively, after verifying the confirmation consensus capability of the K candidate auxiliary node groups, if (K-n) auxiliary node group confirmation information and n auxiliary node group rejection information are received, updating the n candidate auxiliary node groups corresponding to the auxiliary node group rejection information to the (k+n) th candidate auxiliary node group with the candidate auxiliary node group weight bit sequence located at (k+n), and deleting the n candidate auxiliary node groups corresponding to the n auxiliary node group rejection information from the auxiliary node group list and updating the bit sequences of all the candidate auxiliary node group weights again. The application does not limit the sequence of processing the auxiliary node group acknowledgement information or auxiliary node group rejection information by the control platform and the number of simultaneous processing.

It may be appreciated that after updating the corresponding one or more candidate auxiliary node groups in the auxiliary node group list, if the corresponding candidate auxiliary node group in the auxiliary node group list needs to be deleted or added, one or more candidate auxiliary node groups and corresponding anchor cells included in the auxiliary node group list included in the auxiliary node group request are updated, and the updated anchor cells are sent to the updated auxiliary node group request to determine the confirmation consensus capability of the updated candidate auxiliary node groups.

In the data verification method provided by the embodiment of the present application, the control platform determines a plurality of candidate auxiliary node groups through the bit sequence of the auxiliary node group weight value. Wherein, a plurality of candidate auxiliary node groups are respectively corresponding to one anchor point cell one by one. And each anchor point cell confirms the confirmation consensus capacity of the corresponding candidate auxiliary node group respectively, so as to determine the auxiliary node group. Therefore, the auxiliary node group and the terminal auxiliary node corresponding to the anchor point cell determined based on the data verification method ensure the confirmation and consensus capability of the auxiliary node group participating in the data verification consensus, namely, ensure that the anchor point cell corresponding to the auxiliary node group can contain enough terminal auxiliary nodes with data verification qualification, thereby ensuring the reliability in the data verification process.

Fig. 3 is a flowchart of a data verification method according to an embodiment of the present application, and as shown in fig. 3, the data verification method is performed by an anchor cell, and may specifically include:

s301, determining N terminal auxiliary nodes with the front weight bit sequence of the terminal auxiliary node from M terminal auxiliary nodes included in the candidate auxiliary node group.

S302, sending terminal auxiliary node requests to N terminal auxiliary nodes to confirm whether the terminal auxiliary nodes have data verification qualification according to a confirmation result returned by the terminal auxiliary nodes in a preset time. The terminal auxiliary node request is generated by the anchor point cell according to the auxiliary node group request sent by the control platform, and the terminal auxiliary node request also comprises a preset wireless signal quality parameter, wherein the preset wireless signal quality parameter is used for testing whether the terminal auxiliary node has data verification capability or not. Specifically, the description of the preset wireless signal quality parameter for testing whether the terminal auxiliary node has the data verification capability is described in detail below for the specific implementation of step S402.

When the preset number is N, the anchor cell determines N terminal auxiliary nodes with the front terminal auxiliary node weight bit sequence from all the terminal auxiliary nodes (i.e., M terminal auxiliary nodes) after acquiring the terminal auxiliary node weights of all the terminal auxiliary nodes in the candidate auxiliary node group. And sending the terminal auxiliary node request to N terminal auxiliary nodes so that the N terminal auxiliary nodes respectively determine the data verification qualification of the respective terminal auxiliary nodes.

The preset number N may be set according to the requirement. In any implementation, if the number M of the terminal auxiliary nodes included in the candidate auxiliary node group is less than N, auxiliary node group rejection information is sent to the control platform.

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

n=round up (b/K) +m0, equation (2)

Wherein b is the total number of auxiliary nodes required by each participation in the data verification consensus, K is the number of auxiliary node groups required by each participation in the data verification consensus, and M0 is the required terminal auxiliary node allowance. The preset number N acquired by the method can prevent the terminal auxiliary node from moving to other anchor cells in the data verification consensus process, and can not directly establish connection with the anchor cells.

S303b, if the N1 terminal auxiliary nodes are confirmed to have data verification qualification, and N1 is equal to N, determining that the candidate auxiliary node group has the confirmation consensus capability.

If the anchor point cell receives the confirmation results returned by the N terminal auxiliary nodes within the preset time, it is indicated that the candidate auxiliary node group has the capability of confirming and consensus, that is, the anchor point cell can send auxiliary node group confirmation information to the control platform. If the anchor point cell does not receive the confirmation results returned by the N terminal auxiliary nodes within the preset time, the candidate auxiliary node group is not provided with the confirmation consensus capability, namely the anchor point cell can send auxiliary node group rejection information to the control platform.

S303a, if the fact that N1 terminal auxiliary nodes have data verification qualification is confirmed, and N1 is smaller than N, judging whether the current request times are smaller than preset times or not.

The request times refer to the times of simultaneously sending terminal auxiliary node requests to a plurality of terminal auxiliary nodes.

S304, if the current request times are smaller than the preset times, determining (N-N1) terminal auxiliary nodes with the front weight bit sequence of the terminal auxiliary node from the terminal nodes except the N terminal auxiliary nodes in the candidate auxiliary node group, and sending terminal auxiliary node requests to the (N-N1) terminal auxiliary nodes.

And S305, updating N1 according to the number of the terminal auxiliary nodes with data verification qualification in the (N-N1) terminal auxiliary nodes until the request times are equal to the preset times, or N1 is equal to N, or the terminal auxiliary node requests are sent to all the terminal auxiliary nodes.

When the number of the acknowledgement results received by the terminal auxiliary node in the preset time is smaller than the preset number N, the total number of times that the current anchor cell sends the terminal auxiliary node requests to the plurality of terminal auxiliary nodes is counted, and whether the total number of times (i.e. the current requests) reaches the preset number of times is judged. If the current request times are greater than or equal to the preset times, the candidate auxiliary node group is not provided with the capability of confirming consensus, namely the anchor point cell can send auxiliary node group rejection information to the control platform.

Specifically, if the current request times are smaller than the preset times, and if the (N-N1) terminal auxiliary nodes with the front weight bit sequence of the terminal auxiliary node can be selected from the terminal nodes except the N terminal auxiliary nodes in the candidate auxiliary node group, sending terminal auxiliary node requests to the (N-N1) terminal auxiliary nodes, and updating N1 and the update request times according to the number of the terminal auxiliary nodes with data verification qualification in the (N-N1) terminal auxiliary nodes. And judging the updated N1 and N, the updated request times and the preset times.

Specifically, if the current request times are smaller than the preset times and the (N-N1) terminal auxiliary nodes with the front terminal auxiliary node weight bit sequence cannot be selected from the terminal nodes except the N terminal auxiliary nodes in the candidate auxiliary node group, the candidate auxiliary node group is not provided with the capability of confirming consensus, that is, the anchor point cell can send auxiliary node group rejection information to the control platform.

Wherein, according to the number of the terminal auxiliary nodes with data verification qualification in the (N-N1) terminal auxiliary nodes, updating N1 can be understood as updating N1 to (N1+b) if the number of the terminal auxiliary nodes with data verification qualification in the (N-N1) terminal auxiliary nodes is b.

For example, if the anchor cell receives N acknowledgement results returned by N terminal auxiliary nodes in the candidate auxiliary nodes within the preset time Taw1, the anchor cell replies auxiliary node group acknowledgement information to the control platform, and confirms that the N terminal auxiliary nodes of the candidate auxiliary node group act as terminal auxiliary nodes in the data verification consensus.

If the anchor cell only receives N1 auxiliary node acknowledgement messages (N1 < N) in Taw1, the terminal auxiliary node replying the refusal result and the terminal auxiliary node without any reply are abandoned from the N terminal auxiliary nodes of the anchor cell, namely the anchor cell cannot act as the terminal auxiliary node function (even if the follow-up process receives the auxiliary node acknowledgement message sent by the terminal, the follow-up process is abandoned). The terminal auxiliary node cancel message may be transmitted to the terminal auxiliary node that performs the discard process.

Meanwhile, the anchor point cell selects (N-N1) terminal auxiliary nodes with the terminal auxiliary node weight bit sequence being forward according to the terminal auxiliary node weight Wui, sends terminal auxiliary node requests to the (N-N1) terminal auxiliary nodes, adds 1 to the counter Ci1, waits for Taw1 to collect reply messages of the (N-N1) terminal auxiliary nodes, and if the (N-N1) auxiliary node confirmation messages are not collected, namely the total number of the received auxiliary node confirmation messages does not reach N, repeats the steps of sending terminal auxiliary node requests to the (N-N1) terminal auxiliary nodes and judging steps after the steps, continues to search for alternative terminal auxiliary nodes according to the terminal auxiliary node weight Wui, adds 1 to the counter round number Ci1 until N auxiliary nodes are found, and replies auxiliary node group confirmation messages to the control platform. Wherein Ci1 is the round number of the searching counter of the terminal auxiliary node of the anchor point cell, the initial value is 0, and Ci1 can be understood as the round number used for recording the searching of the terminal auxiliary node of the anchor point cell.

Further, if the Ci1 value reaches the preset number of times, N auxiliary node terminals are not found yet, or the anchor point cell has issued a terminal auxiliary node request to all the terminal auxiliary nodes of the candidate auxiliary node group, but N auxiliary node acknowledgement information is not received, or the number of terminal auxiliary nodes in the auxiliary node group list under the candidate auxiliary node group is less than N, the anchor point cell corresponding to the candidate auxiliary node group sends auxiliary node group rejection information to the control platform.

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

Further, the control platform receives the auxiliary node group confirmation information sent by all candidate auxiliary node groups, and takes all candidate auxiliary node groups corresponding to the auxiliary node group confirmation information as all auxiliary node groups to finish auxiliary node group and terminal auxiliary node auxiliary selection.

Further, the control platform sends the determined auxiliary node group to anchor point cells corresponding to all auxiliary node groups in the auxiliary node group list. The auxiliary node group list comprises auxiliary node group identifiers and anchor point cell identifiers of all auxiliary node groups participating in the data verification consensus work at the time.

Fig. 4 is a flowchart of a data verification method according to an exemplary embodiment of the present application, which is specifically a schematic diagram of an interaction process between an anchor cell and a terminal auxiliary node, as shown in fig. 4, where the data verification method may include:

s401, the anchor point cell sends terminal auxiliary node requests to N terminal auxiliary nodes.

S402, the terminal auxiliary node determines whether the terminal auxiliary node has data verification qualification.

S403, the terminal auxiliary node sends a confirmation result with data verification qualification determination for the terminal auxiliary node to the anchor point cell.

S404, the anchor point cell confirms whether the terminal auxiliary node has data verification qualification according to a confirmation result returned by the terminal auxiliary node in a preset time.

The terminal auxiliary node request comprises preset wireless signal quality parameters, wherein the preset wireless signal quality parameters are used for testing whether the terminal auxiliary node has data verification capability or not.

From the above embodiments, it can be seen that, in the embodiments of the present application, the specific interaction procedure between the anchor cell and the terminal auxiliary node in the data verification method in steps S302 to S304. With reference to fig. 3 and fig. 4, in the embodiment of the present application, by means of interaction between the anchor cell and the terminal auxiliary node through the terminal auxiliary node request and the confirmation result, whether N terminal auxiliary nodes with data verification qualification in the candidate auxiliary node group are judged, so as to determine whether the candidate auxiliary node group has the confirmation consensus capability.

Specifically, the anchor point cell collects the acknowledgement result sent by the terminal auxiliary node, and determines the number of the collected acknowledgement results. And when the number of the confirmation results is smaller than the preset number N in each judgment, determining the number of the terminal auxiliary nodes and the terminal auxiliary nodes for retransmitting the terminal auxiliary node request according to the auxiliary node weights of the rest terminal auxiliary nodes. If the number of the confirmation results does not reach N, the process of judging the number of the confirmation results, the number of the requests and sending the requests of the terminal auxiliary nodes is carried out until the number of the requests is equal to the preset number, or the number of the summarized confirmation results is equal to N, or the requests of the terminal auxiliary nodes are sent to all the terminal auxiliary nodes.

As a possible implementation manner, the above step S402 may be implemented in the following manner. The preset wireless signal quality parameter is set to a preset signal receiving power and a preset signal to interference plus noise ratio, wherein the preset signal to interference plus noise ratio refers to a ratio of a pre-stored strength of a received useful signal to a strength of a received interference signal (noise and interference). And under the condition that any one of the terminal auxiliary nodes judges that the receiving power of the reference signal corresponding to any one of the terminal auxiliary nodes is larger than or equal to the receiving power of the preset signal, and the ratio of the signal corresponding to any one of the terminal auxiliary nodes to the interference plus noise is larger than or equal to the ratio of the preset signal to the interference plus noise, the terminal auxiliary node sends a confirmation result to the anchor point cell. And under the condition that any one of the terminal auxiliary nodes determines that the receiving power of the reference signal corresponding to any one of the terminal auxiliary nodes is smaller than the receiving power of the preset signal or the ratio of the signal corresponding to any one of the terminal auxiliary nodes to the interference plus noise is smaller than the ratio of the preset signal to the interference plus noise, the terminal auxiliary node does not send a rejection message to the anchor cell.

The above terminal auxiliary node does not send a rejection message to the anchor cell, and it can be understood that it sends neither an acknowledgement result nor a rejection result to the anchor cell.

Fig. 5 is a flowchart of a data verification method according to an exemplary embodiment of the present application, which specifically is an interaction process schematic of a control platform, an anchor cell, a terminal auxiliary node, and a master node, as shown in fig. 5, where the data verification method may include:

The data verification request may be a data verification request generated by the control platform according to the data to be verified. The data to be verified can be network quality data formed by summarizing measurement reports in a certain time period by a control platform.

For example, the data verification request may be formed from network quality data and recorded timestamp data associated with the network quality data.

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

S503, the master node generates a third verification confirmation request according to the third verification result.

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

As a possible way, step S502 and step S503 may be implemented in the following specific manner. And the master node performs data verification and block packing on the information in the data verification request, and generates a third verification confirmation request by the block data, the block abstract, the time stamp, the block serial number and the block information after block packing and verification.

In some embodiments, the third validation request is encrypted prior to transmission of the third validation request.

S504, the first anchor point cell receives a data verification request sent by the control platform.

The first anchor point cell is an anchor point cell corresponding to any one auxiliary node group.

And S505, the first anchor point cell sends the data verification request to the terminal auxiliary node corresponding to the first anchor point cell.

It can be understood that the control platform does not directly send the data verification request to the terminal auxiliary node, but forwards the data verification request to the terminal auxiliary node corresponding to the first anchor point cell through the first anchor point cell, so that the frequency of sending the data to be verified by the control platform is reduced.

S506, the terminal auxiliary node receives the data verification request sent by the first anchor point cell.

S507, the terminal auxiliary node verifies the data to be verified in the data verification request, and a first verification result is generated.

And S508, the terminal auxiliary node sends the first verification result to the first anchor point cell.

S509, the first anchor cell receives a first verification result returned by the terminal auxiliary node corresponding to the first anchor cell to determine a first verification confirmation request.

It can be understood that each anchor cell gathers the verification results returned by all the corresponding terminal auxiliary nodes to obtain the first verification confirmation request. When the first anchor cell includes N terminal auxiliary nodes, the N terminal auxiliary nodes verify the data to be verified, and then the N terminal auxiliary nodes send respective verification results to the corresponding first anchor cell, and the first anchor cell gathers the N verification results returned by the N terminal auxiliary nodes to obtain a first verification confirmation request. The first verification confirmation request includes a first verification result.

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

Alternatively, the first verification result may include encryption information for the first verification result.

S510, the first anchor point cell sends a first verification confirmation request to the terminal auxiliary node corresponding to the first anchor point cell.

S511, the first anchor cell sends a first authentication confirm request to the master node.

S512, the master node confirms consensus for the first verification result in the first verification confirmation request.

S513, the terminal auxiliary node confirms consensus for the first verification result in the first verification confirmation request.

And sending the first verification confirmation request to the master node and the terminal auxiliary node to complete the confirmation consensus of the master node and the terminal auxiliary node on the first verification result.

It should be noted that, data transmission between terminal auxiliary nodes corresponding to each anchor point cell is also forwarded through the anchor point cell. In detail, the first anchor point cell sends a first verification confirmation request to the second anchor point cell, all the main nodes and the terminal auxiliary nodes corresponding to the first anchor point cell, so that all the terminal auxiliary nodes and all the main nodes confirm the common recognition of the first verification result, wherein the first anchor point cell is the anchor point cell corresponding to any auxiliary node group, and the second anchor point cell is any anchor point cell except the first anchor point cell. The first anchor point cell receives a second verification confirmation request sent by a second anchor point cell, wherein the second verification confirmation request comprises a second verification result of the data to be verified, which corresponds to the second anchor point cell, of the terminal auxiliary node; the first anchor point cell sends a second verification confirmation request to the terminal auxiliary node corresponding to the first anchor point cell, so that the terminal auxiliary node corresponding to the first anchor point cell confirms consensus of the second verification result.

And S514, the master node sends a third verification confirmation request to the first anchor point cell.

It should be noted that, the master node further sends a third verification confirmation request to the second anchor cell, so that the terminal auxiliary node corresponding to the second anchor cell confirms the consensus of the third verification result in the third verification confirmation request. In other words, the master node sends the third verification confirmation request to all the anchor cells, and all the 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 point cell sends a third verification confirmation request to the terminal auxiliary node corresponding to the first anchor point cell.

S517, the terminal auxiliary node confirms consensus for the third verification result in the third verification confirmation request.

Wherein the master node may send a third authentication acknowledgement request to all anchor cells involved in data authentication, i.e. the first anchor cell and the second anchor cell.

It should be noted that, by sending the third verification confirmation request to the anchor cell, the primary node reduces the number of times the primary node transmits data.

When the master node is multiple, the master node forwards the third verification confirmation request of the master node to other master nodes, so that the other master nodes confirm consensus on the third verification result in the third verification confirmation request.

As illustrated in fig. 6 and 7. Fig. 6 is a schematic diagram of data links between nodes in the related art. Fig. 7 is a schematic diagram of data links between nodes according to an embodiment of the present application. Take as an example 2 primary nodes and 6 terminal secondary nodes in fig. 6 and 7. The primary nodes in fig. 6 are Z1 'and Z2', and the terminal secondary nodes are F1', F2', F3', F4', F5 'and F6'. In fig. 7, the primary nodes are Z1 and Z2, the terminal secondary nodes are F1, F2, F3, F4, F5 and F6, and the anchor cells M1 and M2. In the data verification consensus process, when the verification result of the master node Z1' is verified and consensus is performed in the related art, a verification confirmation request needs to be sent to each auxiliary node and each master node, namely 7 times, and in the same way, each node Z1', Z2', F1', F2', F3', F4', F5' and F6' in the data verification consensus process sends the verification result confirmation request 7 times, so that the verification consensus process of all other nodes on the verification result of the node can be completed. In the embodiment of the application, the master node Z1 and Z2 can complete the confirmation and consensus of the verification results of the master node by other nodes only by sending 3 verification confirmation requests. In the embodiment of the application, the auxiliary nodes F1, F2, F3, F4, F5 and F6 can complete the confirmation and consensus of the verification results of all other nodes (all nodes except the node) to the node by only sending a verification confirmation request once. Therefore, the data verification method provided by the application can reduce the communication times of receiving and transmitting data between each auxiliary node and the main node in the data verification consensus process, and reduce the complexity of the data verification consensus process, thereby reducing the power consumption of the terminal and the time delay of the data consensus process.

In this embodiment, the anchor cell and the terminal auxiliary node corresponding to the anchor cell may be obtained through steps S201 to S208 and/or steps S301 to S305 and/or steps S401 to S404 in the provided data verification method. The anchor point cell participating in data verification is further guaranteed to have the capability of confirming consensus, and the terminal auxiliary node corresponding to the anchor point cell has the capability of data verification.

In some embodiments, the master node is built by an operator together, and is responsible for the equipment of block generation and block storage, and the terminal auxiliary node selects a terminal with terminal bearing capacity in the network, namely comprehensively selects based on factors such as terminal capacity, terminal willingness, terminal electric quantity, historical participation and the like. The selected terminal auxiliary node participates in the data block generation verification in the data verification process. And the co-established shared network quality information is stored in a trusted way by matching the main node with the terminal auxiliary node.

It should be noted that, in the above embodiment, after all the master nodes and the terminal slave nodes generate the verification result confirmation consensus in the verification confirmation request, the corresponding confirmation consensus result is generated and then directly sent to the control platform. The method comprises the steps that a confirmation consensus result corresponding to each node is marked as Cji, the nodes are any one main node and any one terminal auxiliary node, the verification confirmation request comprises a first verification confirmation request generated by a first anchor point cell according to a first verification result, a second verification confirmation request generated by a second anchor point cell according to a second verification result, and a third verification confirmation request generated by the main node according to a third verification result, and the second anchor point cell is any anchor point cell except the first anchor point cell.

In some embodiments, after performing steps S510 to S517, the control platform determines the target consensus result according to the received acknowledgement consensus results sent by all the terminal auxiliary nodes and all the main nodes.

Illustratively, after receiving the confirmation consensus results sent by all the master nodes and the terminal auxiliary nodes, the control platform generates a confirmation consensus result set { Cij } for the verification of the verification results of other nodes by each node (wherein Cji is the confirmation consensus result of node j to node i, and j is not equal to i). The control platform determines the master node with the largest sum of the confirmation consensus results of other nodes in each master node to the master node based on the verification set { Cij } sent by each node, and takes the verification result corresponding to the largest master node as a target consensus result, and broadcasts the target consensus result to all the master nodes so that all the master nodes store the target consensus result. In some embodiments, the target consensus result is typically the best block data.

Through the above embodiment, after generating the data verification request according to the data to be verified, the control platform sends the generated data verification request to all anchor cells and all master nodes. And forwarding the received data verification request to all terminal auxiliary nodes corresponding to the anchor point cells. Thus, the verification of the data to be verified by all the terminal auxiliary nodes and all the main nodes is completed. After verification is completed, on one hand, the master node sends verification results generated by verifying the data to be verified to other master nodes and all anchor point cells respectively so as to complete confirmation and consensus of the verification results of all master nodes by all master nodes and all terminal auxiliary nodes. And simultaneously, all the terminal auxiliary nodes send verification results generated by respective verification of the data to be verified to respective corresponding anchor point cells. And on the other hand, each anchor cell gathers all verification results sent by all terminal auxiliary nodes corresponding to the received anchor cells, so as to determine verification determination requests corresponding to the anchor cells. And all the anchor point cells send the corresponding verification confirmation requests to other anchor point cells, all the main nodes and all the terminal auxiliary nodes corresponding to the anchor point cells so as to complete the confirmation consensus of the verification results of all the main nodes and all the terminal auxiliary nodes to all the terminal auxiliary nodes.
