Step S101, each conventional node selects one conventional node from a plurality of conventional nodes as a packing node of the next block according to the block content of the latest block in the block chain and the mobile phone number broadcasted to the block chain network.
The packing node of the next block is obtained by selecting a plurality of conventional nodes in the block chain network, and is acknowledged by the conventional nodes in the block chain network, so that each conventional node in the block chain network can select one conventional node from the conventional nodes as the packing node of the next block according to the block content of the latest block in the block chain and the mobile phone number broadcasted to the block chain network, the workload is simplified, and the problem of resource waste caused by competition of the packing right of the block among the nodes through workload certification in the prior art is solved.

Fig. 2 is a flowchart illustrating a method for selecting a packing node based on a mobile phone number according to another embodiment of the present invention. The method is applied to a blockchain network, wherein the blockchain network comprises a plurality of conventional nodes, as shown in fig. 2, and the method comprises the following steps:
and step S200, each conventional node signs the mobile phone number by using the private key of the node, broadcasts the mobile phone number and the signature to the block chain network in a transaction mode and writes the mobile phone number and the signature into the block chain.
Specifically, each conventional node needs to register a mobile phone number, an association relationship between the mobile phone number and the node is established after registration, the private key has uniqueness, the mobile phone number is signed by using the private key of the node, other conventional nodes in the block chain network can conveniently verify the ownership of the mobile phone number, the mobile phone number is signed by using the private key of the node, and the mobile phone number and the signature are broadcasted to the block chain network in a transaction mode and written into the block chain.
Step S201, each conventional node traverses the query block chain, and generates a list for recording the mapping relationship between the node and the mobile phone number.
Each regular node may traverse the query blockchain, obtain the association relationship between the node and the mobile phone number from the blockchain, and then generate a list recording the mapping relationship between the node and the mobile phone number, for example, the list may be as shown in table 1, which is only an example and does not have any limiting effect.
Table 1:
specifically, in the embodiment of the present invention, the packing node of the next block may be selected by the method defined in step S202 to step S204:
in step S202, each regular node performs hash processing on the block content of the latest block in the block chain by using a preset hash algorithm to obtain a first hash value.
Each regular node may obtain the tile content of the latest tile in the tile chain, and then hash the obtained tile content of the latest tile by using a preset hash algorithm, for example, MD2, MD4, MD5, SHA-1, to obtain a first hash value corresponding to the tile content of the latest tile, where a few hash algorithms are simply listed here, and a person skilled in the art may select a corresponding hash algorithm according to actual needs, and the hash algorithms are not listed here.
Step S203, each conventional node performs hash processing on the plurality of mobile phone numbers by using a preset hash algorithm to obtain a plurality of second hash values.
Specifically, each conventional node may obtain a mobile phone number from the generated list, and then perform hash processing on each mobile phone number by using a preset hash algorithm, for example, MD2, MD4, MD5, and SHA-1, to obtain a second hash value corresponding to each mobile phone number, where the hash algorithm used when performing hash processing on the tile content of the latest tile by each conventional node is the same as the hash algorithm used when performing hash processing on the mobile phone number.
In the present invention, the execution sequence of step S202 and step S203 is not limited, and step S202 may be executed before or after step S203, or step S202 and step S203 may be executed simultaneously.
Step S204, selecting a second hash value with the smallest difference from the first hash value from the plurality of second hash values according to the first hash value, and using a conventional node corresponding to the mobile phone number corresponding to the second hash value as a packing node of the next block.
After the first hash value and the plurality of second hash values are obtained, the difference value between each second hash value and the first hash value can be calculated respectively, the difference values can be sorted in an ascending order or a descending order, the second hash value with the minimum difference value with the first hash value is determined, the corresponding mobile phone number is determined according to the second hash value, the list is inquired according to the mobile phone number, the conventional node corresponding to the mobile phone number is obtained, and the conventional node is used as the packing node of the next block.
In step S205, each regular node selects a first preset number of regular nodes from the plurality of regular nodes as verification nodes for verifying the packed block according to the block content of the latest block in the block chain and the mobile phone number broadcasted to the block chain network.
In order to prevent the selected packing node from cheating, in the embodiment of the present invention, a first preset number of regular nodes are further required to be selected from the plurality of regular nodes as verification nodes for verifying the packing block, where the first preset number may be set according to actual needs, for example, three regular nodes may be selected as verification nodes for verifying the packing block, which is only an example and does not have any limiting function.
Specifically, the verification node may be selected by the following method: and each conventional node performs hash processing on the block content of the latest block in the block chain by using different hash algorithms according to the number of verification nodes to be selected to obtain a plurality of third hash values, each conventional node performs hash processing on a plurality of mobile phone numbers by using a corresponding hash algorithm to obtain a plurality of fourth hash values, for each third hash value, one fourth hash value with the minimum difference value with the third hash value is selected from the plurality of fourth hash values according to the third hash value, and the conventional node corresponding to the mobile phone number corresponding to the selected fourth hash value is used as the verification node for verifying the packed block.
Supposing that three verification nodes are to be selected, each conventional node performs hash processing on the block content of the latest block in the block chain by using three different hash algorithms to obtain three third hash values, each conventional node can also perform hash processing on the mobile phone numbers in the list by using the corresponding hash algorithm to obtain a plurality of fourth hash values, the difference value between each fourth hash value and each third hash value can be calculated for each third hash value, then the difference values are sorted in an ascending order or a descending order to determine the fourth hash value with the minimum difference value with the third hash values, the corresponding mobile phone number is determined according to the fourth hash value, the list is queried according to the mobile phone numbers to obtain the conventional node corresponding to the mobile phone number, and the conventional node is used as the verification node, so that the three conventional nodes are selected to be used as the verification nodes. The hashing algorithm used here is different from the hashing algorithm used when selecting packing nodes.
And step S206, the verification nodes respectively send verification codes to the mobile phone numbers corresponding to the packaging nodes in a short message mode, and the hash values of the verification codes are broadcast to the block chain network.
Each verification node can randomly generate a verification code, the verification code is sent to a mobile phone number corresponding to the packaging node in a short message mode, then the verification nodes perform Hash processing on the verification code by using a preset Hash algorithm to obtain a Hash value corresponding to the verification code, the Hash value of the verification code is broadcasted to a block chain network, if the verification nodes broadcast the verification code directly, the packaging node can cheat easily under the condition that the verification code is acquired, and the Hash value of the broadcast verification code can avoid cheating of the packaging node.
Step S207, the packaging node packages the transactions in the transaction pool into a block, and broadcasts the block and the received verification code to the blockchain network.
After the conventional node selected as the packing node acquires the packing right, the transaction in the transaction pool is packed into a block, the block and the received verification code are broadcasted to the block chain network, and the block is verified by other unselected conventional nodes in the block chain network.
And S208, verifying the packaging node by other unselected conventional nodes in the block chain network according to the hash value of the verification code broadcast by the verification node, and if the verification code broadcast by the packaging node is matched with the hash value of the verification code broadcast by the verification node and the number of the verification codes broadcast by the packaging node is greater than or equal to a second preset number, confirming that the packaging node obtains the packaging right of the next block, and adding the block into the block chain copy of the node.
The verification of the block by other non-selected conventional nodes in the block chain network mainly includes verifying whether the verification code sent by the packing node is consistent with the verification code sent by the verification node, and whether the number of the verification codes broadcast by the packing node meets the requirement, that is, whether the number of the verification codes is greater than or equal to a second preset number, for example, if three verification nodes are selected in step S205 to verify the block, the second preset number may be set to 2, that is, the number of the verification codes broadcast by the packing node into the block chain network needs to be greater than or equal to 2 to meet the number requirement.
Specifically, after acquiring the verification codes broadcasted by the packing nodes to the blockchain network, other non-selected conventional nodes in the blockchain network may first determine whether the number of the verification codes broadcasted by the packing nodes is equal to or less than a second preset number, and if not, the packing nodes may be determined not to obtain the packing right, and the broadcasted blocks are not verified and cannot be added to the blockchain copy; if the verification code broadcasted by the packaging node is consistent with the hash value of the verification code broadcasted by the verification node, the packaging node can be considered to obtain the packaging right, and the block is added into the block chain copy of the node.
After the block verification passes, a certain reward can be distributed to the conventional nodes as the packaging node and the verification node for rewarding the labor of the conventional nodes.
The scheme provided by the embodiment of the invention utilizes the uniqueness of the mobile phone number and the characteristic of difficult forgery of short message verification, and takes the mobile phone number as the basis of the distribution of the packing right, thereby realizing the effect of reasonably and fairly selecting the packing node by each conventional node in a block chain network, avoiding the resource waste caused by workload certification and saving the time required by packing the transaction into blocks.
Fig. 3 is a flowchart illustrating a method for selecting a packing node based on a mobile phone number according to another embodiment of the present invention. The method is applied to a blockchain network, wherein the blockchain network comprises a plurality of conventional nodes, as shown in fig. 3, and the method comprises the following steps:
in step S300, each regular node broadcasts the association of the mobile phone number corresponding to the node to the blockchain network.
Specifically, each conventional node needs to register a mobile phone number, an association relationship between the mobile phone number and the node is established after registration, and then the mobile phone number corresponding to the node is broadcast to the blockchain network in an associated manner. By broadcasting the mobile phone number corresponding to the node into the blockchain network, the conventional node in the blockchain network can select a verification node for verifying the mobile phone number of the node conveniently according to the mobile phone number.
Step S301, each conventional node performs hash processing on the mobile phone number of the node by using different hash algorithms according to the number of verification nodes to be selected, so as to obtain a plurality of fifth hash values.
The mobile phone number of each conventional node in the blockchain network needs to be verified, and if three verification nodes need to be selected, each conventional node performs hash processing on the registered mobile phone numbers respectively by using three different hash algorithms, for example, MD4, MD5, and SHA-1, to obtain three fifth hash values.
Step S302, each regular node performs hash processing on other mobile phone numbers broadcasted to the blockchain network by using a corresponding hash algorithm, so as to obtain a plurality of sixth hash values.
Each conventional node may also acquire other mobile phone numbers broadcasted to the blockchain network, and after acquiring other mobile phone numbers in the blockchain network, may perform hash processing on the acquired other mobile phone numbers by using a corresponding hash algorithm, for example, MD4, MD5, and SHA-1, to obtain a plurality of sixth hash values. The embodiment of the invention carries out hash processing on the mobile phone number, and is convenient for selecting the verification node according to the hash value in the follow-up process.
Step S303, for each fifth hash value, selecting a sixth hash value having the smallest difference from the fifth hash values according to the fifth hash value, and using a regular node corresponding to the mobile phone number corresponding to the selected sixth hash value as a verification node.
After the fifth hash value and the plurality of sixth hash values are obtained, the difference between each sixth hash value and the fifth hash value can be respectively calculated, the differences can be sorted in an ascending order or a descending order, the sixth hash value with the smallest difference with the fifth hash value is determined, the corresponding mobile phone number is determined according to the sixth hash value, the conventional node corresponding to the mobile phone number is determined, and the conventional node is used as a verification node.
And step S304, the verification nodes respectively send verification codes to the mobile phone numbers corresponding to the conventional nodes in a short message mode, and the hash values of the verification codes are broadcast to the block chain network.
Each verification node can randomly generate a verification code, the verification code is sent to a mobile phone number corresponding to the conventional node in a short message mode, then the verification nodes perform hash processing on the verification code by using a preset hash algorithm to obtain a hash value corresponding to the verification code, the hash value of the verification code is broadcasted to the block chain network, if the verification nodes broadcast the verification code directly, the conventional node can cheat easily under the condition that the verification code is obtained, and the broadcast hash value of the verification code can avoid cheating of the conventional node.
In step S305, the regular node broadcasts the received verification code to the blockchain network.
Step S306, other conventional nodes which are not selected in the block chain network verify the conventional node according to the hash value of the verification code broadcast by the verification node, and if the verification code broadcast by the conventional node is matched with the hash value of the verification code broadcast by the verification node and the number of the verification codes broadcast by the conventional node is greater than or equal to a second preset number, the conventional node is confirmed to pass verification.
For example, if three verification nodes are selected in step S303 to verify the conventional node, the second preset number may be set to 2, that is, the number of the verification codes broadcast by the conventional node to the blockchain network needs to be greater than or equal to 2 to meet the number requirement.
Specifically, after acquiring the verification code broadcasted by the regular node to the blockchain network, other non-selected regular nodes in the blockchain network may first determine whether the number of the verification codes broadcasted by the regular node is equal to or less than a second preset number, and if not, the regular node may be determined to be not verified and cannot be selected as a packing node in the subsequent steps; if so, performing hash processing on the verification code broadcasted by the conventional node by using a preset hash algorithm to obtain a hash value corresponding to the verification code broadcasted by the conventional node, matching the hash value corresponding to the verification code broadcasted by the conventional node with the hash value of the verification code broadcasted by the verification node, and if the hash values are consistent, determining that the conventional node passes verification to obtain the qualification of becoming a packaging node.
Step S307, each regular node broadcasts the node and the cell phone number corresponding to the node to the blockchain network in an associated manner, and writes the node and the cell phone number into the blockchain.
Step S308, each conventional node traverses the query block chain to generate a list for recording the mapping relation between the nodes and the mobile phone numbers.
Each regular node may traverse the query blockchain, obtain the association relationship between the node and the mobile phone number from the blockchain, and then generate a list recording the mapping relationship between the node and the mobile phone number, where the list is shown in table 1 for example, and this list is only an example and does not have any limitation.
Table 1:
| conventional node 1 | 13365985655 |
| Regular node 2 | 15682884558 |
| Regular node 3 | 17758956895 |
| Regular node 4 | 18625634598 |
In step S309, each conventional node selects one conventional node from the plurality of conventional nodes as a packing node of the next block according to the block content of the latest block in the block chain and the mobile phone number broadcasted to the block chain network.
Specifically, the following method may be adopted to select a conventional node as the packing node of the next block:
each regular node may obtain the tile content of the latest tile in the tile chain, and then perform hash processing on the obtained tile content of the latest tile by using a preset hash algorithm, for example, MD2, MD4, MD5, SHA-1, to obtain a first hash value corresponding to the tile content of the latest tile.
Each conventional node may obtain a mobile phone number from the generated list, and then perform hash processing on each mobile phone number by using a preset hash algorithm, for example, MD2, MD4, MD5, and SHA-1, to obtain a second hash value corresponding to each mobile phone number, where the hash algorithm used when performing hash processing on the tile content of the latest tile by each conventional node is the same as the hash algorithm used when performing hash processing on the mobile phone number. The hash algorithms are only briefly listed here, and those skilled in the art can select the corresponding hash algorithm according to actual needs, which is not listed here.
After the first hash value and the plurality of second hash values are obtained, the difference value between each second hash value and the first hash value can be calculated respectively, the difference values can be sorted in an ascending order or a descending order, the second hash value with the minimum difference value with the first hash value is determined, the corresponding mobile phone number is determined according to the second hash value, the list is inquired according to the mobile phone number, the conventional node corresponding to the mobile phone number is obtained, and the conventional node is used as the packing node of the next block.
In step S310, the packaging node packages the transactions in the transaction pool into a block and broadcasts the block to the blockchain network.
After the conventional node selected as the packing node obtains the packing right, the transaction in the transaction pool is packed into a block, the block is broadcasted to the block chain network, and other conventional nodes which are not selected in the block chain network add the block into the block chain copy of the node.
In step S311, after receiving the broadcasted block, other regular nodes that are not selected in the blockchain network add the block to the blockchain copy of the node itself.
Here, other conventional nodes in the blockchain network that are not selected will not verify that the packet node broadcasts to the blocks in the blockchain network.
The embodiment of fig. 3 differs from the embodiment of fig. 2 in that the embodiment of fig. 3 verifies the cell phone number before broadcasting the association of the node and the cell phone number to the blockchain network, so that after determining the packing node, no further verification is required.
In an optional embodiment of the present invention, the packing node and the verification node may be determined according to the serial numbers by numbering the mobile phone numbers in the list, and specifically, the following method may be adopted:
sequentially numbering mobile phone numbers in a list for recording the mapping relation between the nodes and the mobile phone numbers, and performing hash processing on the block content of the latest block in the block chain by each conventional node by using a preset hash algorithm to obtain a seventh hash value; and taking the conventional node corresponding to the mobile phone number corresponding to the number value matched with the seventh hash value in the list as the packing node of the next block.
Each conventional node respectively performs hash processing on the block content of the latest block in the block chain by using different hash algorithms according to the number of verification nodes to be selected to obtain a plurality of eighth hash values; and regarding each eighth hash value, taking a conventional node corresponding to the mobile phone number corresponding to the number value matched with the eighth hash value in the list as a verification node for verifying the packaging block.
In an optional embodiment of the present invention, in order to prevent the problem of block packing blocking caused by that the selected regular node does not respond to information in time, other regular nodes that are not selected in the block chain network may set a blacklist mechanism according to a time required for block packing, and add the regular nodes that are not packed or verified for many times to a blacklist, specifically, the method may be implemented by:
and detecting whether the selected group of packing nodes and verification nodes finish block packing within preset time by other conventional nodes which are not selected in the block chain network, and if not, reselecting the group of packing nodes and verification nodes to pack the next block.
The other non-selected conventional nodes in the block chain network detect whether the number of times that the selected packing node is not packed within a preset time period after receiving the verification code is greater than or equal to a first preset threshold, and if so, add the conventional node selected as the packing node to a blacklist, wherein the first preset threshold may be set according to actual needs, for example, set to 3 times, which is only an example and does not have any limiting effect.
Other conventional nodes which are not selected in the block chain network detect whether the number of times that the selected verification node is not checked is greater than or equal to a second preset threshold, if so, the conventional node which is selected as the verification node is added to a blacklist, wherein the second preset threshold can be set according to actual needs, for example, set to 5 times, which is only an example and does not have any limiting effect.
The scheme provided by the embodiment of the invention utilizes the uniqueness of the mobile phone number and the characteristic of difficult forgery of short message verification, and takes the mobile phone number as the basis of the distribution of the packing right, thereby realizing the effect of reasonably and fairly selecting the packing node by each conventional node in a block chain network, avoiding the resource waste caused by workload certification and saving the time required by packing the transaction into blocks.
